We've moved to Pueblo, Colorado, I have a lovely (and smart-as-a-whip) Grand-daughter, and a new cat (the two are, in fact, logically related), I'm no longer in PA practice (though trying to re-enter), the shop's in pieces from the move (still), and My Lady Wife is happily ensconced in a new position with BuR.</span><br />
<span style="font-family: Times, Times New Roman, serif; font-size: large;"><br /></span>
<span style="font-family: Times, Times New Roman, serif; font-size: large;">We love Pueblo, and always knew we'd end up in the southwest eventually, things just happened a little sooner . . . </span><span style="font-family: Times, 'Times New Roman', serif; font-size: large;">The new house has a lovely view of the mountains, but sometimes I miss my trees. </span><br />
<span style="font-family: Times, Times New Roman, serif; font-size: large;"><br /></span>
<span style="font-family: Times, Times New Roman, serif; font-size: large;">So, Gen has been after me to restart my blog for a while now, new moves, new friends, new hobbies, etc. and I knew I'd get around to it sooner or later, but now, tah-dah, <i>new information</i>!</span><br />
<span style="font-family: Times, Times New Roman, serif; font-size: large;"><br /></span>
<span style="font-family: Times, Times New Roman, serif; font-size: large;">Buried somewhere back in the dog cart posts I mentioned that the only extant primary source we have for a dog cart is an illumination in the 13th century <i>Decretals of Gregory</i> (the so called <i>Smithfield Decretals</i>). When I started the cart the British Museum had taken down the image from their web site. They sent me a very nice reply to an email back then saying basically, "we only have so much space on the server, and we decided to take that book down and have no plans to put it back up, but we'll happily sell you a copy of the image at an exorbitant price."</span><br />
<span style="font-family: Times, Times New Roman, serif; font-size: large;"><br /></span>
<span style="font-family: Times, Times New Roman, serif; font-size: large;">Kingdom A&S approaches in the Outlands and I've decided to finish the last tweaks, make a few re-dos, complete smithing the harness parts, and enter the Dog Cart. Step one was to recheck the British Museum's price for a copy of the pic, when, lo and behold! the manuscript's back up!</span><br />

<span style="font-family: Times New Roman, serif; font-size: large;">So, now that we have an image we can expand--where'd I go wrong? I still maintain a basket weave for the cart bed is a logical choice, but we can see in the illumination the sides are "clinker built" of over lapping boards clinch nailed at the overlap. We can also reasonably conjecture that the bed may have been built more like a coffer or palanquin and the poles do indeed mount central to the bed sides and were not extensions of the bed's frame.</span></div>

<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Times New Roman, serif; font-size: large;">From the harness we can see the straps that cross the near dog's shoulders are wider than is common in modern dog carting. Also the lead dog and second dog are not harnessed like a modern dog sled, but that the lead dog's leather strap traces run to a central point in the second dog's yoke, and the second dog's rope traces run to the poles, not the near dog's harness.</span></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Times New Roman, serif; font-size: large;"><br /></span></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Times New Roman, serif; font-size: large;">Interestingly, the pulling straps are only the yokes, there are no straps around the bodies of the dogs.</span></div>

<span style="font-family: Times, Times New Roman, serif; font-size: large;">The lead looks a little "hang dog' (pun intended) because this arrangement means he's doing most of the work. The unhappy looking guy in back is probably pushing because the happier looking near and second dogs are slacking off--or maybe he just thinks it's his turn to ride?</span></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Times, Times New Roman, serif; font-size: large;"><br /></span></div>
<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Times, Times New Roman, serif; font-size: large;">Another conjecture for the rational of a dog cart also occurred to me when I looked at this picture. The rider in the blue cote is winding a hunting horn. A dog cart would be useful for bringing in dressed game from a hunt for boar or stag.</span></div>
<div class="separator" style="clear: both; text-align: left;">

<div class="separator" style="clear: both; text-align: left;">
<span style="font-family: Times, Times New Roman, serif; font-size: large;">I'm really glad the British Museum elected to put this fascinating work back-up, and even gladder I hadn't made the harness.</span></div>

I'm on the road for a bit, so I'm sorting the big stack of pics for the oseberg cart, and some (a lot) of really crappily organized notes; but I'm working (perforce) with Horvendile (the laptop--man, I miss those two big monitors) and it's a pain, but we'll get there.<br /><br />So, I recently found out I'm going to be a grandfather... I'm alternating between happily bumfuzzled and "I'm too young to be a grandfather!"<br /><br />OK, logically, 53 isn't isn't exactly the first blush of youth, but as I often say: childhood is fleeting, but immaturity can last <em>forever.</em> (Gen pointedly agrees, sigh) Anyway, I've wanted to build a cradle for a while (I've got a measured drawing of a period one stashed somewhere). Grandkids, sheesh, I only graduated high school 35 years ago.... Well, maybe I'm not too old to be a granddad, but I'm certainly not mature enough; though I always wanted eccentric grandparents (mine were nice, don't get me wrong, but they were pretty staid), my daughters, OTOH have been blessed with a lovably eccentric grandmother (my mom, 78, red hat, screaming red sox fan, conducts a kazoo band--'nuff said).<br /><br />I'm thinking this could be fun...<br /><br />McKMcKennahttp://www.blogger.com/profile/06500140415090961892noreply@blogger.com0tag:blogger.com,1999:blog-1426182256452590355.post-35496830711365767402010-06-01T17:01:00.002-04:002010-06-01T17:07:50.309-04:00Zzzzzzaaapppp!So, that ozoney smell seems to be coming from a lightning-fried modem. Until the new one arrives from Amazon in a day or two I'm limited to a crappy little laptop. Trying to move all the pics and text from the Fafnir (the big computer) to Horvendile (the crappy little laptop) and edit a post is just too much bother with all the other stuff I have to get done before the in-laws arrive this weekend.<br /><br />Assuming all goes well, I'll have the posts finishing up the dog cart up on Friday, and Monday we'll be starting a new wagon (the oseberg).<br /><br />McKMcKennahttp://www.blogger.com/profile/06500140415090961892noreply@blogger.com0tag:blogger.com,1999:blog-1426182256452590355.post-91874229789255755902010-05-24T23:11:00.007-04:002010-05-27T12:35:14.509-04:00O what a tangled web we weave<div><div><div>So far we've cut down trees, chopped up wood, made poles, crossbars, wheels, and assembled the frame.

There are innumerable options for this stage. After a lot of thought I concluded the best way would be cross bars at the front and back with mortise and tenons to the poles, with the poles slid through mortises in the axle. Thus no fasteners required, and as the green wood shrinks it pulls all the joinery tighter together. Above is a view from the back with the wheels mounted on the axles.<div><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj1w3RI-B_ifEfNZSp4IrxfPl6DxqeKhcSPlMHWzdSc6fHcUccEyDBcVatDaRR8sbpFOz00VDL2hXSo6F5CJGLD8Ss69ipQMMfCsbQ5j1_Eeuqk0naykuZKRI6gjucJV6gPbqV2zSJG5_S6/s1600/Dsc04342.jpg"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj1w3RI-B_ifEfNZSp4IrxfPl6DxqeKhcSPlMHWzdSc6fHcUccEyDBcVatDaRR8sbpFOz00VDL2hXSo6F5CJGLD8Ss69ipQMMfCsbQ5j1_Eeuqk0naykuZKRI6gjucJV6gPbqV2zSJG5_S6/s320/Dsc04342.jpg" border="0" alt="" id="BLOGGER_PHOTO_ID_5474861809586127154" style="display: block; margin-top: 0px; margin-right: auto; margin-bottom: 10px; margin-left: auto; text-align: center; cursor: pointer; width: 320px; height: 240px; " /></a><br /></div><div>This is the right (starboard) pole passing through the axle tree.</div><div><br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg7UnLi8-mklkqjQVqK9oz8xxG4NUyVKxh4FW1i1XiWDMURvRqBozwLFSzuvd_Y6JCkhG8JS5isQgQasGoQI1EiJF3XY1V-_-ynwi2R4WltmxkLlvaXbMH_wuEQzqvNTjBA_mxy3qqtWc5I/s1600/Dsc04340.jpg"></a></div><div><br /></div><div><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg7UnLi8-mklkqjQVqK9oz8xxG4NUyVKxh4FW1i1XiWDMURvRqBozwLFSzuvd_Y6JCkhG8JS5isQgQasGoQI1EiJF3XY1V-_-ynwi2R4WltmxkLlvaXbMH_wuEQzqvNTjBA_mxy3qqtWc5I/s1600/Dsc04340.jpg"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg7UnLi8-mklkqjQVqK9oz8xxG4NUyVKxh4FW1i1XiWDMURvRqBozwLFSzuvd_Y6JCkhG8JS5isQgQasGoQI1EiJF3XY1V-_-ynwi2R4WltmxkLlvaXbMH_wuEQzqvNTjBA_mxy3qqtWc5I/s320/Dsc04340.jpg" border="0" alt="" id="BLOGGER_PHOTO_ID_5474861806383465730" style="text-align: left; display: block; margin-top: 0px; margin-right: auto; margin-bottom: 10px; margin-left: auto; cursor: pointer; width: 320px; height: 240px; " /></a><br /></div><div>This is the front cross bar tenoned into the starboard pole</div><div><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgjOJrTgnakXIVOAfnLUg84fXmrT7Wiq3Sb2ldKbdgDyzztaVf322QuadEdZfNf3HmsoGZFrFhlC_zEphs7bhe8MJFXuKi0p4P076klEQ-HCTNJU6w_UvXD1EsqXj_i8fbi58ONUkPSdvfh/s1600/frame+2.jpg"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgjOJrTgnakXIVOAfnLUg84fXmrT7Wiq3Sb2ldKbdgDyzztaVf322QuadEdZfNf3HmsoGZFrFhlC_zEphs7bhe8MJFXuKi0p4P076klEQ-HCTNJU6w_UvXD1EsqXj_i8fbi58ONUkPSdvfh/s320/frame+2.jpg" border="0" alt="" id="BLOGGER_PHOTO_ID_5474861801264092930" style="display: block; margin-top: 0px; margin-right: auto; margin-bottom: 10px; margin-left: auto; text-align: center; cursor: pointer; width: 320px; height: 240px; " /></a><br /></div><div>And here is the rear cross bar tenoned into the starboard pole.</div><div><br /></div><div>There's nothing exceptionally complicated about the crossbars. The poles were set parallel about the right distance to clear the dog's shoulders at the front and two boards were ripped to slightly longer than the width of the cart. The were then tenoned with the shoulders set to the inner distance between poles. The mortises were angled slightly so that the crossbars tilt out at their tops about 7 degrees.</div><div><br /></div><div>The Axletree though is much more complex.

The board cracked between the mortise and the end during the first try fitting. I spread the crack slightly, shot in glue, and then bolted the split end back together nice and strong.

This picture doesn't show it yet, but after the curved piece is mounted you should roll a piece of pipe so it comes to rest at the very 'bottom dead center' and make a reference mark.</span></span></span></span><div><span><span><span class="Apple-style-span" style="font-family:'times new roman';"><span class="Apple-style-span" style="font-size: medium;"><br /></span></span></span></span></div><div><span><span><span class="Apple-style-span" style="font-family:'times new roman';"><span class="Apple-style-span" style="font-size: medium;">The felloe then gets set in the jig like so:</span></span></span></span></div><div><span><span><span class="Apple-style-span" style="font-family:'times new roman';"><span class="Apple-style-span" style="font-size: medium;"><br /></span></span></span></span></div><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgsz_tkcRmHw-hwNNmWxlqy6PRvvDLN075sDoGoc_7J77p6UgH-laq7x9pFu1chKISKjxtbTHSBuNbQv-xCuv8ZCSa4_sim9aW2P3npgiVHwaZv0_LrVlQs6yYSfQbhkTs4LT1NotTiffxy/s1600/drilling+felloe.jpg"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgsz_tkcRmHw-hwNNmWxlqy6PRvvDLN075sDoGoc_7J77p6UgH-laq7x9pFu1chKISKjxtbTHSBuNbQv-xCuv8ZCSa4_sim9aW2P3npgiVHwaZv0_LrVlQs6yYSfQbhkTs4LT1NotTiffxy/s320/drilling+felloe.jpg" border="0" alt="" id="BLOGGER_PHOTO_ID_5474245928869301282" style="display: block; margin-top: 0px; margin-right: auto; margin-bottom: 10px; margin-left: auto; text-align: center; cursor: pointer; width: 320px; height: 240px; " /></a><div><p class="MsoNormal"><span class="Apple-style-span" style="font-family:'times new roman';"><span class="Apple-style-span" style="font-size: medium;"><o:p></o:p></span></span></p><p class="MsoNormal"></p><span><span><span class="Apple-style-span" style="font-family:'times new roman';"><span class="Apple-style-span" style="font-size: medium;">Let me back up a sec. Normally when you're cutting you make the cut a bit proud of the line and go back and shape later. The felloe pattern should be cut as close as possible to a tight fit on the spokes, and the felloes should be cut as exactly as possible so they fit the jig (and the wheel).</span></span></span></span></div><div><span><span><span class="Apple-style-span" style="font-family:'times new roman';"><span class="Apple-style-span" style="font-size: medium;"><br /></span></span></span></span></div><div><span><span><span class="Apple-style-span" style="font-family:'times new roman';"><span class="Apple-style-span" style="font-size: medium;">I also see I missed a step with the spokes.

Use clamps. When the saw is fired up the wheel is rotated and the dado blade trims the end of spokes so they are perfectly centered on the axle hole. The hub/spoke assembly is then returned to wheel jig</span></span></span></span></p></div><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj371WhbomaTpFDpA6bd1QzBmD9JHprahvgAg7169B169Ws6S9VtNWgXJCwJm07U1kCwv4WjlscpGwkNVerrXRpfp8RkDxWETC5gZcoN7Hfz6Q1nP2j3jhSNs8dLbiO4D9w1shcmaEBuJgl/s1600/Dsc04309.jpg"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj371WhbomaTpFDpA6bd1QzBmD9JHprahvgAg7169B169Ws6S9VtNWgXJCwJm07U1kCwv4WjlscpGwkNVerrXRpfp8RkDxWETC5gZcoN7Hfz6Q1nP2j3jhSNs8dLbiO4D9w1shcmaEBuJgl/s320/Dsc04309.jpg" border="0" alt="" id="BLOGGER_PHOTO_ID_5474248008854867650" style="display: block; margin-top: 0px; margin-right: auto; margin-bottom: 10px; margin-left: auto; text-align: center; cursor: pointer; width: 240px; height: 320px; " /></a><div><p class="MsoNormal"><span><span><span class="Apple-style-span" style="font-size: medium;"><span class="Apple-style-span" style="font-family:'times new roman';"></span></span></span></span></p><span><span><p class="MsoNormal"></p><span><span><span class="Apple-style-span" style="font-family:'times new roman';"><span class="Apple-style-span" style="font-size: medium;">and a combination square is used to set the distance from the tenon end to the shoulder.</span></span></span></span></span></span><p></p><p class="MsoNormal"><span><span><span><span><span class="Apple-style-span" style="font-family:'times new roman';"><span class="Apple-style-span" style="font-size: medium;">On one tenon I found the shoulder too far from the end (the others all required little or no trimming).</span></span></span></span></span></span></p></div><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiAARM71V9F2xgWKhfA5KFj3fyfaeH0-CL70eJMYV1xaOY13d9lJT17-6PWphOvtHFyD2JQVzreVwW_sxeMBEBqimhwy0P3QIGpUTfdtoeXwhkO9XhlZdr_qNQb-dh5HjWAY292Jq5yOm2w/s1600/Dsc04313.jpg"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiAARM71V9F2xgWKhfA5KFj3fyfaeH0-CL70eJMYV1xaOY13d9lJT17-6PWphOvtHFyD2JQVzreVwW_sxeMBEBqimhwy0P3QIGpUTfdtoeXwhkO9XhlZdr_qNQb-dh5HjWAY292Jq5yOm2w/s320/Dsc04313.jpg" border="0" alt="" id="BLOGGER_PHOTO_ID_5474249468640372178" style="display: block; margin-top: 0px; margin-right: auto; margin-bottom: 10px; margin-left: auto; text-align: center; cursor: pointer; width: 320px; height: 240px; " /></a><p class="MsoNormal"></p><span><span><span class="Apple-style-span" style="font-family:'times new roman';"><span class="Apple-style-span" style="font-size: medium;">This was fixed by gluing a wood "washer" in place and trimming with a coping saw and shaping with a Dremel to match the decorative cove of the spoke--the repair is unnoticeable.</span></span></span></span><div><span><span><span class="Apple-style-span" style="font-family:'times new roman';"><span class="Apple-style-span" style="font-size: medium;"><br /></span></span></span></span></div><div><span><span><span class="Apple-style-span" style="font-family:'times new roman';"><span class="Apple-style-span" style="font-size: medium;">Okay, back to that felloe we left sitting in the jig. Drill out a mortise deep enough to fit the tenon and go back and dry fit. Oh, yeah, make sure when you marked the felloe you marked which mortise goes to which spoke. Dry fit the felloes to the wheel. When every thing fits together well it's time to glue the felloes together. Some builders recommend a dowel or spline in the joint between felloes for alignment and support. Since this wheel is for such a light weight cart I didn't bother. Instead, I used "Gorilla Glue" which expands into the wood on both sides of a joint, and in the case of pine, makes a joint stronger than the surrounding wood.</span></span></span></span></div><div><span><span><span class="Apple-style-span" style="font-family:'times new roman';"><span class="Apple-style-span" style="font-size: medium;"><br /></span></span></span></span></div><div><span><span><span class="Apple-style-span" style="font-family:'times new roman';"><span class="Apple-style-span" style="font-size: medium;">I slathered on the glue put waxed paper over the joints, and then used a strap clamp (cargo strap with ratchet) to pull the felloes tight.

The waxed paper is to keep the squeezed out glue from gluing the strap and clamps to the wheel.</span></span></span></span><p class="MsoNormal"></p></div><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEijbt3zHAVFX_BaB7COEiTBBEhyphenhyphen8qkzW8eN8rsVh1bMSTvGWFAyPHR0DgycCjBinW9l2XQR4rSOk-wWUQ1T7MSZ3YBrp4NB1SjhFT2sBEcDpetJWUldQZkIWaqgqUr8zNaozzqTJ8N3h-qi/s1600/shaping+wheel.jpg"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEijbt3zHAVFX_BaB7COEiTBBEhyphenhyphen8qkzW8eN8rsVh1bMSTvGWFAyPHR0DgycCjBinW9l2XQR4rSOk-wWUQ1T7MSZ3YBrp4NB1SjhFT2sBEcDpetJWUldQZkIWaqgqUr8zNaozzqTJ8N3h-qi/s320/shaping+wheel.jpg" border="0" alt="" id="BLOGGER_PHOTO_ID_5474250663344033554" style="display: block; margin-top: 0px; margin-right: auto; margin-bottom: 10px; margin-left: auto; text-align: center; cursor: pointer; width: 320px; height: 240px; " /></a><p class="MsoNormal"></p><span><span><span class="Apple-style-span" style="font-family:'times new roman';"><span class="Apple-style-span" style="font-size: medium;">When all the glue is dry I popped the wheel in the workmate bench (a wonderfully useful tool) and sanded everything up nice and smooth.</span></span></span></span><div><span><span><span class="Apple-style-span" style="font-family:'times new roman';"><span class="Apple-style-span" style="font-size: medium;"><br /></span></span></span></span></div><div><span><span><span class="Apple-style-span" style="font-family:'times new roman';"><span class="Apple-style-span" style="font-size: medium;">If you look back to the first picture you see that between the spokes the wheel has been carved away a bit.

Time to step back and admire your handiwork. Let me mention again that making spoked wheels is a lengthy, finicky, tedious, irritating process. From the description here it sounds like you only dry fit a few times, in reality it's over and over and over and over. I respect anyone who goes to the trouble of making spoked wheels, but truly, for most SCA uses I wouldn't bother. Though another nifty aspect is that once you've made all these jigs later wheels are easier, and you can make spinning wheels, too.

First, the hubs.</p><p>Once again the hubs were mounted in the hub fiddle and given another light sanding. There was some light checking from unequal shrinkage of the drying wood. This was expected. Drying billets of wood without checking is virtually impossible. If the checking had split through at one of the spoke mortises I'd have been screwed, but luck held and the checks are all minor and cosmetic. Eventually they were filled with homemade wood putty--sawdust (really fine dusty stuff from the spindle sander) mixed with glue. I know this method has been used since at least the 1700s. Though I've never come across a reference to a period piece having been filled in such a manner, it seems to me logical that if a period woodworker was faced with filling such a gap he would either cut small wedges of wood and drive them in or just ignore the checks, or stuff some oakum mixed with hide glue in the crack. We do know that in <span class="blsp-spelling-error" id="SPELLING_ERROR_3">shipwrighting</span> checks were filled with oakum/pine tar. Not having any oakum, and not liking the stickiness of pine tar, I went with this.</p></div><span><span>Wheel hubs check, thus hub irons (hub bronzes?) were put on the hubs. We have many of these found in wagon graves from the bronze age. To make them I went to the scrap pile and pulled out some 3" bronze fittings still soldered to some old drain pipe I'd pulled. Some work with the torch and the fittings were off, then the hub of the fitting was cut off with an angle grinder with a metal cutting blade, and cleaned up on the wire wheel.</span></span></div><div><span><span><br /></span></span></div><div><span><span>Using the <span class="blsp-spelling-error" id="SPELLING_ERROR_4">dremel</span> with a coarse sanding bit I carved down the hub to slightly <span class="blsp-spelling-error" id="SPELLING_ERROR_5">oversized</span> (just enough bigger I had to use a hammer to start it). Then I took the hub outside, set the hub iron in place, put a piece of 2x6 over it and whaled away with a 10 pound sledge. Them suckers are on. Okay, were on. Some further shrinkage loosened one to the extent that I <span class="blsp-spelling-error" id="SPELLING_ERROR_6">resoldered</span> a piece of copper pipe in it, narrowing it and restoring the friction fit.The last thing to be done to prep the hubs for the spokes was to flatten a shoulder from the spoke to rest on (marked in red).</span></span><div id="ygrp-text"><p><span class="Apple-style-span" style="border-collapse: collapse; color: rgb(51, 51, 51); line-height: 18px; -webkit-border-horizontal-spacing: 2px; -webkit-border-vertical-spacing: 2px; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); line-height: normal; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; "><span class="Apple-style-span" style="font-family:'times new roman';"><span class="Apple-style-span" style="font-size:medium;"></span></span></span></span></p><p><span class="Apple-style-span" style="border-collapse: collapse; color: rgb(51, 51, 51); line-height: 18px; -webkit-border-horizontal-spacing: 2px; -webkit-border-vertical-spacing: 2px; "><span class="Apple-style-span" style="font-family:'times new roman';"><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); line-height: normal; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; font-family:Georgia, serif;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgkoNtcZii6x5ADBGlNP9TlCbAlJZuOKgSLXDh5nNck8ipPPb-HjmYvKh2W_Efx5a-ewR2ABfxo8rz4Km3AI5dzOr_QQ8iG3NBxWMp43qAjEnI8tjugxPy-RxxfYl0h2g4XDQseZG7HfSDm/s1600/spoke+shoulder+marked.jpg"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgkoNtcZii6x5ADBGlNP9TlCbAlJZuOKgSLXDh5nNck8ipPPb-HjmYvKh2W_Efx5a-ewR2ABfxo8rz4Km3AI5dzOr_QQ8iG3NBxWMp43qAjEnI8tjugxPy-RxxfYl0h2g4XDQseZG7HfSDm/s320/spoke+shoulder+marked.jpg" border="0" alt="" id="BLOGGER_PHOTO_ID_5473081667289908722" style="display: block; margin-top: 0px; margin-right: auto; margin-bottom: 10px; margin-left: auto; text-align: center; cursor: pointer; width: 320px; height: 240px; " /></a></span></span></span></p><span class="Apple-style-span" style="font-family:'times new roman';"><div id="ygrp-text"></div></span><p></p><p><span class="Apple-style-span" style="border-collapse: collapse; color: rgb(51, 51, 51); line-height: 18px; -webkit-border-horizontal-spacing: 2px; -webkit-border-vertical-spacing: 2px; "><span class="Apple-style-span" style="font-family:'times new roman';"><span class="Apple-style-span" style="font-size:medium;"></span></span></span></p><span><span>The mortises were labeled with roman numerals for the starboard hub and letters for the port. This is <i>essential</i> as the tenons are cut to fit a particular mortise perfectly, and when done will only fit that mortise. Once the hub irons were taken care of it was time to move on to the spokes. I mentioned earlier I had wanted to use green oak from a tree that came down in a storm, but the wood turned out to have been "beetled." So I eventually went with some seasoned oak from an old project. The first step was to cut out blanks (with extras). The center of one end was found and marked. </span></span></div><div id="ygrp-text"><span><span><br /></span></span></div><div id="ygrp-text"><span><span>I made a jig to hold the spokes upright and square in the drill press and using a plug cutting bit shaped the round tenon that will go into the mortise of the <span class="blsp-spelling-error" id="SPELLING_ERROR_7">felloes</span>.</span></span><p><span class="Apple-style-span" style="border-collapse: collapse; color: rgb(51, 51, 51); line-height: 18px; -webkit-border-horizontal-spacing: 2px; -webkit-border-vertical-spacing: 2px; "><span class="Apple-style-span" style="font-family:'times new roman';"><span class="Apple-style-span" style="font-size:medium;"></span></span></span></p></div><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhT7tP80ImB5Y4u3mg4KnFIQ9efY-WJL6r9GcJU-qdOJEcGOZ6BVtTlKgMklA-etX5UW0ooNbTZQi7jLpXjL5oXgyF6K05PztffAXEkau-ciMXsJp6rH28111r53shZQdVCnVdr_JJoTgaC/s1600/spoke+felloe+tenon+jig2.jpg"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhT7tP80ImB5Y4u3mg4KnFIQ9efY-WJL6r9GcJU-qdOJEcGOZ6BVtTlKgMklA-etX5UW0ooNbTZQi7jLpXjL5oXgyF6K05PztffAXEkau-ciMXsJp6rH28111r53shZQdVCnVdr_JJoTgaC/s320/spoke+felloe+tenon+jig2.jpg" border="0" alt="" id="BLOGGER_PHOTO_ID_5473088145601609698" style="display: block; margin-top: 0px; margin-right: auto; margin-bottom: 10px; margin-left: auto; text-align: center; cursor: pointer; width: 240px; height: 320px; " /></a><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhlPsIFSK3Cx8TSCKAsfaXDyEaQFdGQVoAbVYlUfuHJlBWFk_jKacuCbIhh7P8ij9MK4QSAv2mwsfdawZyWPH_lLlP9FdItBTbAqEAFnFEslIj3y1E-tOdP_lEFRFupt-7V34t7uFMAAiSe/s1600/spoke+felloe+tenon+jig.jpg"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhlPsIFSK3Cx8TSCKAsfaXDyEaQFdGQVoAbVYlUfuHJlBWFk_jKacuCbIhh7P8ij9MK4QSAv2mwsfdawZyWPH_lLlP9FdItBTbAqEAFnFEslIj3y1E-tOdP_lEFRFupt-7V34t7uFMAAiSe/s320/spoke+felloe+tenon+jig.jpg" border="0" alt="" id="BLOGGER_PHOTO_ID_5473091226479716690" style="display: block; margin-top: 0px; margin-right: auto; margin-bottom: 10px; margin-left: auto; text-align: center; cursor: pointer; width: 320px; height: 240px; " /></a><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEge9c-g68zAP08YyXD4hcTd8-FCdQCORkspp-_R79BHLd076XeLzjqfULjBvdvmuReP5-vWoFmWe2jdP59wz71I9-UmaKQGYln3tAhG2oTaegFnDckCvKXfCvlyfV8wt9Xx-Aa8IAH91zGY/s1600/cutting+spoke_felloe+tenon.jpg"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEge9c-g68zAP08YyXD4hcTd8-FCdQCORkspp-_R79BHLd076XeLzjqfULjBvdvmuReP5-vWoFmWe2jdP59wz71I9-UmaKQGYln3tAhG2oTaegFnDckCvKXfCvlyfV8wt9Xx-Aa8IAH91zGY/s320/cutting+spoke_felloe+tenon.jpg" border="0" alt="" id="BLOGGER_PHOTO_ID_5473091226268896530" style="display: block; margin-top: 0px; margin-right: auto; margin-bottom: 10px; margin-left: auto; text-align: center; cursor: pointer; width: 320px; height: 240px; " /></a>Once this was done the tenons were cut on the opposite end using the dado head on the table saw.

A woman who didn't just grow old gracefully, but exuberantly. She was well past sixty when I had her for English, History, Homeroom, and I count myself lucky to have known her. Silver-haired, clear eyed, with a tongue like an adze, a mind like a razor, and a zeal and zest for teaching. If you picture the heroine from "Titanic" as the old woman, combine her with the best of Peter O'Toole's "Mr. Chips," and add a dash Puck, that was Miss Diana Hill. When I was in 7th grade I took oil painting lessons, and Miss Diana Hill was another student in the artist's class, still trying new things.<br /><br />We say "kids these days don't know what it was like way back when;" a trite expression, but I truly regret my daughters never got to hear from her what WWI was like to a teenager, or how families came both together and apart in the great depression, about letters from former students from Anzio, and Truk, and Iwo, about Lindburgh and Apollo, and the first time a television came to town, and being faced with a mimeograph with no instructions--talk about the terrors of technology. So much of our past is vision that can't be shared; bright, personal images that are fleeting as soap bubbles.<br /><br />Anyway, this poem has been running through my head as I've cut trees, planed "white wood that cuts like cheese" and tried to get into the head of a 14th century joiner, whilst using 21st century tools.

When we bought our house 8 years ago shortly before our wedding I 'guesstimated' a five year renovation plan. Despite being a lifelong conservative there must be some Bolshevik in me as I haven't come close to meeting any five year plan yet. Sigh.<br /><p>The house had a very large 2.5 car garage. When we moved in I started out putting the McKennawerks in the garage, since it had nice 10' ceilings; but Gen, bless her, kept bugging me to move to the much larger basement area, even though it has a lower ceiling, insisting I would need the room. She was right, of course, as she almost always is. Having the extra floor space was needed. According to McKenna's Shop Law: the workshop always expands to fill the available space. This inevitably left a 25'x 26' garage to do something with. </p><p>A few years on we found a beautiful leaded glass front door with side lights and a palladian window at lowe's for $500, one tenth it's list price. It had been returned twice for being too large. When we spotted it on yet another Lowe's run Gen innocently said, "I wonder how much they want for that?" I logically responded, "Waaaay more than we can afford, that thing's <em>at least </em>3 grand, new." Despite my impeccable logic Gen went off to ask the manager how much. His response was, "If you <em>promise</em> not to bring it, back how does $500 sound?" Score!</p><p>Of course, even with 10' ceilings it was too tall, so emergency crash remodel project # 473 rip out 16' steel garage door, frame new opening, and reframe rafters to install a cathedral ceiling to clear the 11.5' palladian window. The decision was made to go with a "morrocan" decorating theme, and in fits and starts we've added storage, a raised section of floor enclosed for a laundry room and half bath, installed a wood burning stove, new wiring, new high "E" windows, ad exhausteum. </p><p>But now we've finally gotten close enough to finishing that Gen has declared that she wants one room totally, completely, absolutely, done -- or I walk the plank. </p><p>Anyway, to save life and limb I've been putting a lot of time into finishing the "Peacock Room," named for the subject of a huge beautiful stained glass window I brought back from Tijuana. In the course of the last month, between trying to get the dog-cart ready for Kingdom A&S I've been plumbing, wiring, installing track lighting, painting, taping sheetrock, and getting ready to venetian plaster the ceiling preparatory to tiling the floor (the tile has been 'aging' gracefully in storage since about a month after we bought the house--it was on sale at another Lowe's closing sale for about 10 cents/sq.ft.). </p><p>On the dog-cart project, much was done, but until about the last 9 days much of it was "more of the same." The second side pole was cut, shaped, steamed, and fortunately didn't split, the wheel hubs dressed, and parts cut for later assembly. Then once laundry room mostly done, and with deadlines fast approaching I declared that since the washer and dryer were once again working I was off to the McKennawerks--hold my calls.</p><p>After a marathon of flying sawdust I had only the paperwork left to do, and at the last minute the #&^$ing computer swallowed my file folder of documentation without a burp.

After many years of searching I finally came across an illustration of such a period use. So we can say that at least the concept was not totally foreign to a medieval person.</div><div> </div><div>It should be noted in the woodcut that one of the conventions Burgkmair employed in his woodcuts was to make the saint being portrayed "larger than life." Therefore, the cart should be regarded as proportional to the unfortunate leper, not to the 'heroically' sized St. Edward.</div><div> </div><div>The picture is found in "Bottoms Up!

As I mentioned, the colder the environment the quicker your workpiece looses plasticity; and since I'm using a propane camp stove as one of the heat sources the doors and windows need to be open for ventilation.<br /><br />News Flash: McKennawerks goes high-tech!<br /><br />Thanks to the technical expertise of Generica, My Lady Wife, I'm beginning blogging this from the laptop down in the bowels of the McKennawerks. Gen, with the able assistance of our computer guru friend Gregor, were finally able to get the wireless router to recognize the laptops, so we can compute while sitting in front of the warm woodstove, instead of at the main computer which lives in the coldest corner of the house. Apparently wireless routers don't like dial-up, and it took some doing to convince it that, yes, while we are still stuck in the middle ages courtesy of Verizon, we really do want to use more than one computer.<br /><br />I've also added a hit counter just for the heck of it. I looked at adding a guestbook as well, but after checking out some on other blogs it appears that the comments are mostly banal, off-topic, spam, or obscene. I'll just stick with google's comment widget. And of course you can email me at McKenna(one word)werksatgmaildotcom. I don't normally bring anything of a sensitive electronic nature down here due to the ever present dust and potential for (fragile and expensive) things to be accidentally knocked to the concrete floor, but we're in a holding pattern because we've started to steam.<br /><br />So it's time to talk about some of the specifics of steam bending wood. It requires one hour per inch thickness of wood, plus (in this case) bringing 3 gallons of water up to a rolling boil. Fine Woodworking has a good book on many different bending techniques. If you're interested in some in-depth knowledge about how the pros do it you should check it out. I've not steam bent anything in ages and ages, I much prefer cold lamination with glue for bending to steaming. The steaming part of steam bending is easy and straight forward: where the problems arise is in the bending part.<br /><br />To bend wood with steam we need:<br />--patience of the saints<br />--time<br />--safety equipment<br />--a source of steam<br />--wood to be bent<br />--a form to bend the wood over<br /><br />Patience. While wood, especially green wood, is flexible to an extent, it doesn't like to bend and stay bent. Depending on many factors, especially thickness and grain of the workpiece and amount of curve, you can expect a failure rate of 50% or more. This should elicit no more than a muted, "Darn." If breaking wood is going to send you into a cat-throwing, obscenity yelling, jumping-up-and-down rage, stick with lamination.<br /><br />Time. You need an hour per inch thickness of wood, and it doesn't start until a good head of steam is built up. Then you have to get the wood instantaneously into the form while maintaining a serene calm.<br /><br />Safety. For safety for this project I wore high leather boots in case of a spill: I didn't want boiling water splashing my ankles and soaking into sneakers. There was a fire extinguisher close to hand, and I wore good leather gloves throughout the process in case I needed to grab something hot.<br /><br />As in metal casting, though, if something starts to "go" it's usually a lot smarter to back off and let it and clean up the mess, than to risk a burn by grabbing at something. Eye protection, of course, is essential.<br /><br />Steam. For the source of the steam I'm using an old turkey fryer that I actually bought with steam bending in mind. Several years ago we held an early spring outdoor event where we made a big pot of lentil soup (and roasted a pig, yummm). Since then the cooker has been sitting at the back of the shop awaiting the day I finally decided to steam bend.<br /><br />For this bend I started by heating about 3 gallons of water with a hot plate, but it took a long time to get it up to a low boil, and couldn't really get it up to the rolling boil we need. So I switched to a propane camp stove. This was an improvement, but if I weren't doing a one-off project, I think I'd bite the bullet and fill up the propane tank for the gas grill and use the turkey fryer stand. </span><br /><div><div><div><div><div><div><div><div><div><div><img id="BLOGGER_PHOTO_ID_5305018902106740002" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 240px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh0hICsA4SiMnGvJR-VAeEz8M8QuvLtsp0WQd62oXy5n_6pU1URk_j5HBOIh6vXOVzePop1yqicpRqbyKNZRPCi7X4JtGfulQF8ZFtCa72pkX7E-LpjnCQfS5vOHwXskrJiKnVr4GsuvDwp/s320/steaming1.jpg" border="0" /><span><span>In the lid of the fryer I drilled a hole for ¾" copper pipe and just stuck it in place with friction. I still want to be able to use the fryer as a stock pot, so I didn't silver solder it in place. There was an existing hole in the lid for inserting a thermometer, which I loosely plugged with a bit of sanded down dowel. It's very important that you DON'T heat in a closed system, this plug served as a safety valve. </span></span><img id="BLOGGER_PHOTO_ID_5305018900657163074" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 240px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh90kQmVdHQwWvyMJIB0gCV87gM5mFC0mD_Eu8Cv-Q1N8949g0v_I_Mnb8HQYFqxwbyNxd7wi5tCQQQBiM4RRfve1t5mEf5zUY8kK1DrHac5JAFMpYYLBltiqVjqehrgqRSKqn9lNbasAH9/s320/steaming2.jpg" border="0" /><br /><span><span><br />For the steam box I used an old piece of 4" thin wall pvc drain pipe. I cut a plywood plug for one end and drilled out a hole for the inlet pipe near the bottom edge of the plug. As water condenses from the steam in the steambox it will run back into the boiler. Again, avoiding a closed system, I left the irregularities in the edge of the plug from cutting it out with the sabre saw in place. The pipe clamp you can see around the end was due to concern that the heat might soften the plastic to where the friction fitted plug would slip out. It's just helping the pipe retain it's shape--it is not clamping the plug in place.<br /><br />The piece of pipe I had lying around was too short for the 9' long poles so I extended it with flexible aluminum clothes dryer hose. </span></span><br /></div><div><img id="BLOGGER_PHOTO_ID_5305018017454794018" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 240px; CURSOR: hand; HEIGHT: 320px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjFkXwLJ5rDuluEcIX48tLEfYE12GqEX5qvJKEUWtAMybNIwvN2XAog438iLF8dUSVmD9ZWtnoMDDikdOu7VRLH8SDXenRQTiGSWC_4L9aWUGC7XQmS_qXLBpQXbukqzZSrez3w2gqjmHpr/s320/steam+box.jpg" border="0" />I had planned to use the dryer hose for the entire pole if it proved too curvy to fit in the pvc pipe, but after releasing them from the temporary clamping they sprang back fairly straight. If you look carefully at the plug (which is a 4" round cut from a 2x6) you'll note two holes. They are there for allowing stem to escape and the thermometer. The center hole was later drilled wider to accept a piece of 1" copper pipe used as a union for the automobile heater hose.</div><br /><div>A test run showed the long box was too long for the amount of steam generated with the small camp stove. The thermometer only registered about 160 degrees F. at the far end.<br /><br /></div><div><img id="BLOGGER_PHOTO_ID_5305018013191041794" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 240px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiCoz2sQMqR5Rkelpy4ej9U8kjA4vCl1FMrGGSbBUToYUqFSNgn1CbiTdmtnaIDZT5gIT71NoTogHrPfzpX4iY25vEsIpT8BMX5SkUxcWwLxpBBMRB1x1ZLJqXjRkARO4NdwEoMp9-of_yf/s320/coffeepot3.jpg" border="0" />So I supplemented the system by putting a camp coffee pot on the hot plate at the opposite end of the steam box. <img id="BLOGGER_PHOTO_ID_5305018008742299170" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 240px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgkfY2lpVGVz0z0ZRj4jMnZrn4FuV8qeXLcGG2GNvbWtJli-DLl1lJTR4KqDChTZoe_P_vY1z4a8RDpnkPyFGkI3Aj3J5Wow6DiS_Cn2Lb4V4Kt6W-B1kVPneZkSCxUayZEkhg-YKlb_ucM/s320/coffeepot2.jpg" border="0" />I stuffed an automobile heater hose scrap (left over from a wagon tire) into the spout and jammed a few small bits of cloth into the gap. As Tennessee Tuxedo used to say, "If you make do with what you've got, then you won't need what you have not."<br /><br /></div><div><img id="BLOGGER_PHOTO_ID_5305019718428669570" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 240px; CURSOR: hand; HEIGHT: 320px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgbsbvrldy3cUEdNd6v0LcWTxavAo9xKRwSDsgbg7iwU7pz3TfoR_1YRJqFXfOpJm-8ttQYKetRcny-lzxvvlsqhVnFd0hsTZ7V_8ig3EskvslqGcuzi4WD8P2UAVZBQc3Wktf9qUuCS2SN/s320/thermometer.jpg" border="0" /><span>When the pot began to boil the temperature quickly rose to 212 deg. F and more steam began to leak from the untightened lids and fittings, showing an increase in steam pressure within the box. I'm using the meat thermometer which came with the turkey fryer--waste not, want not. (I'm just full of aphorisms today)<br /><br />Wood. The wood I'm using is (probably) ash. Oak, ash, and hickory are widely considered the best woods to use steam bending with. Don't bother with pine-it'll split. The thicker the piece, the longer it needs in the steambox (one hour per inch) and the more likely it is to split. The tighter or more extreme the curve the more likely it is to split. Also try to use pieces with long straight grain, it's more likely to crack where the grain 'runs out' to the edge of the wood. It's easier to stream green wood. Kiln dried wood does not steam well. If you're stuck with MegaLoweMart lumber, I'd strongly suggest considering glued up laminations.<br /><br />Form. The form for bending was made from scrap lying around the shop. There is a good distance between points where the blocks push against the piece to be bent. If we were making furniture or boats where precision is a prerequisite we'd make the bending form almost continuous along the bend, but such precision isn't needed here, and would not have been bothered with by our hypothetical medieval craftsman.<br /><br />To use it we need lots of clamps. Lots and lots of clamps. If you don't have them there are work arounds to clamps that I covered in an earlier post. The other thing is to make sure you do a dry run. Have all the clamps laid out to hand. Have a hammer ready to hand to help tap along the piece if necessary to overcome friction against the mold. It's really better to do one piece at a time, but since one piece was so close to the desired bends, to save clamping and drilling holes in the bending form to take clamp ends I went with doing both pieces at once.<br /><br />To do this I placed small pieces of 1/4" dowel between the pieces as spacers,and used cable ties to hold them together in rough alignment. Once the boilers had built up a good head of steam they were ensconced in the steam box. Then we wait.<br /><br />After a tad over an hour (the pieces are a tad over an inch thick) I pulled them from the steam box and stuffed the front ends under a cross piece and forced the back under another cross piece at that end. Then frantically began clamping. The starboard piece went in fine, but the port was a little stiff. Unfortunately, after about 20 minutes in the form there was a sudden crack! and the port piece split at the compound curve where the harness hitch would be.<br /></span><br /><img id="BLOGGER_PHOTO_ID_5305337678207044034" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 240px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg58x3JiuDb6wxQhw2dGAYDbaheaegZIVIha5mQF6ebiI7KwuNpCHhwZIeVaNuI6Y64_z_H94eYDV4fkOGQO0YWioVkgh_0MUJfjjsl4Vcgl6w8saoFxICP9mwSflvwR7ZWMGOAxQb8i_yM/s320/split.jpg" border="0" /><span>This is not a total disaster, as I have plenty of wood to make another pole from, and I can cut pieces from the split pole to use in other parts of the cart.<br /><br />Post mortem analysis shows that I left the split piece a little wider than the other intending to trim it down to size after bending--I should have made it the same width as the other. Secondly, when I was clamping it there was more resistance than the other so I should have aborted the clamping, let the wood cool for 24 hrs and started over. Impatience is often my besetting sin. Also, I probably shouldn't have done both at the same time. There's a lot of truth in the old saw, "if you don't have time to do it right, will you have time to do it over?"<br /><br />As I said above-expect splits. I'm disappointed it didn't go perfectly, but it's not going to impact the deadline.<br /><br />McK<br /><br /><br /></span></div></div></div></div></div></div></div></div></div></div></div>McKennahttp://www.blogger.com/profile/06500140415090961892noreply@blogger.com0tag:blogger.com,1999:blog-1426182256452590355.post-91463808614775623342009-02-19T21:14:00.002-05:002009-02-19T22:31:11.892-05:00More pole musings<span>We had one warm day, so biting the bullet I went ahead with the bending. The McKennawerks is now once again uncomfortably cold. The steam bending went pretty well but it's going to be a very long post, and I'm still editing and adding things in so it will be another day before I get it done. It's late. I'm tired and heading off to bed so I'll just put this up now.<br /><br />It occured to me while sitting there waiting for the poles to finish steaming that there is another argument in favor of steam bending the poles.<br /><br />In period illustrations of both wheelbarrows and plows you can see arching handles or shafts. Some of these are apparently cut to curves from wider boards, but some appear either steam bent or cut from tree stock of the correct curve. Thus, we can reasonably infer that curved and compound curved pieces of farm equipment would be recognizable to our period craftsman, and considered as a solution to minimizing the weight of the cart without enlarging the wheels.<br /><br />Here's a few illuminations to illustrate my point.</span><br /><span><br /> </span><span></span><br /><div><div><div><div><div><div><div><img id="BLOGGER_PHOTO_ID_5304704228247603058" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 150px; CURSOR: hand; HEIGHT: 86px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi4Gzt2jE57SIO6529H9AwAj18mgi2aG67EniVmhDkrDVGF-xEF8q5DPqoev3ULhzR11UPF7-clncEW5CdD4tJhgRNts3Pfeo3gBYJltEi5LG_JMYkusZtDWt-f_rZLGnxuae-ccrw1_KMa/s320/Lutrell+wheelbarrow.jpg" border="0" /></div><div>The wheelbarrow is from the Lutrell Psalter, the same book which has the illumination we are using as our inspiration piece.

It's gotten cold again, and I'm not sanguine about how successful I'd be in a frigid shop. Wood is bent with steaming by heat and moisture making plastic the hemicelluloses in the wood fibers. As soon as you remove the piece from the steam box is instantly begins to lose malleability as a function of cooling. Since these are long pieces, requiring many clamps, and shaping into a complex compound curve, I'm concerned that in a cold shop I won't have adequate working time to bend the poles without cracking.</div><div><br /></div><div>I've made some test pieces and we'll give those a shot first.</div><div><br /></div><p>(Later on...)</p><p><span>Man, I'm tickled pink! I got so pleased with the way the poles are turning out I had to drag Gen down to the McKennawerks in her jammies just so I could share with somebody. I thought the shop was still too cold for steaming, but I went ahead and built, scratch that, cobbled together, the bending jig. As you can see from the below pictures, the first pole I cut is nearly perfect just cold clamped in the jig, and the second pole is very nearly there, too.</span></p><p><span></span><img id="BLOGGER_PHOTO_ID_5303971902839540946" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 240px; CURSOR: hand; HEIGHT: 320px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg0gQP9J1s_08Y-vF3BZJdKbbGYmrcbgAGGsWKza3Dzn28E169WJ1fmigGh_tJPj2fLGEXYJV3eZhjw7JGwWutMLcTaEhyphenhyphenK2FZrPT-g39yZQrILUVotcZD0NoDMuwHr1ko9ZChgQYPTNHi3/s320/pole+bending+jig2.jpg" border="0" /></p><p><img id="BLOGGER_PHOTO_ID_5303971905938112626" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 240px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg17xLAiZZoLxOQ3fGzAYq4-3CVNS3mYlLfghs88koCzXlJGfD3CcV8FlryABvWp5-avLc4EqOBYNZd5jb9Wpg8OEzVHG95yz1cDqNiwpU7xSVT8AufpLW5qNnsbd7k-BH_Hsz9TdRxnKoJ/s320/pole+bending+jig.jpg" border="0" /></p><div>Of course, at this point the wood is still green and springy, and as soon as I pull the clamps off it springs back too far to be useful. But this means that when I steam them they should conform to the blocking fairly easily.

You can see that the blocking for the jig is built up of odds and ends of scrap. The "C" clamp is hooked on the bottom to a super heavy duty clothes rod mount. I pulled a bunch of them out of the MBR closet 7 years ago when working on remolding the MBR--<em>never</em> throw <em>anything</em> away, that's what I always say (Gen always says, "Whatinthehell are you going to do with that old thing!).<br /><br /><p>mck<br /></p></div></div>McKennahttp://www.blogger.com/profile/06500140415090961892noreply@blogger.com1tag:blogger.com,1999:blog-1426182256452590355.post-45775615781437631812009-02-16T21:19:00.003-05:002009-02-16T22:03:26.363-05:00Starting to get shaftedBack to conjecturing...<br /><br />As previously noted we're faced with drawing conclusions from period iconography of horse carts to design our dog-cart. The Lutrell Psalter has several representations of wagons, but all of them have straight shafts. Should we not use straight shafts as well? <br /><br />There are what I believe are several logical reasons not to.<br /><br />First, let's be honest, the curved shafts are more aesthetically pleasing, and if I'm going to all this work I want something that looks cool. What can I say.<br /><br />Second, in line with the conceit that this cart would have been built at an on-site workshop of a monastery or latifundia it's not unreasonable to assume bent poles. If we are to keep the bed level, and not spill our goods on the ground we cannot use straight shafts. They would require larger wheels, with a consequent increase in weight. Remember, we're not looking at a cart to be pulled by a heavy draft horse or ox, but by a dog. The load is limited. Every ounce more in cart weight is an ounce less of potential useful load. The cart would be made as light as possible to make the load as great as possible.<br /><br />Third, the craftsmen of such an estate would have had ready access to coppice. It took me only a few minutes walking around to find two suitable poles. For my full-size Djebjerg Wagon project I have several pieces of very complex curved natural growth seasoning. It took me about an hour wandering through the woods to find the two trees I used. If it's this easy in 21st century mid-America to find suitably curved standing wood, how much easier must it have been in a more heavily forested and coppiced medieval Europe. Additionally, our hypothetical craftsman would not have been under a deadline--he could have bent trees and allowed them to grow to shape as was done for boat building.<br /><br />So I think it's not inconceivable our craftsman would have elected to use smaller, sturdier, lighter wheels, and use poles that curved to a useful height and distance.<br /><br />Unfortunately, finding <em>perfect</em> poles is not as easy as finding fairly good ones. To get what we need is going to require more than careful shaping with the drawknife. Thus we'll need to steam bend the poles to get the desired compound curves. We know that steam bending was done in period by furniture makers and boat builders so the technique is appropriate. And I don't think it's stretching our conjecture too far to posit that our craftsman would have used it rather than spend large amounts of time searching for just the two perfect pieces of wood.<br /><br />Today I cut the second pole and shaped it as with the first one. Since it didn't match exactly with the old one we'll correct the differences with steam.<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgw9kOJDuh-IWH0Vklg8VetqU7ylh1I_IghXrAj38CEe3ccLAquw9F9Dh_Dbj0mYp9-fBfZ7ZdegZem2rxHTQ5H0YPe5oGvF747E75ZqEMwKInZRH4ou2Ps6_zuXK3ar0kWE3fHI0-Ig30-/s1600-h/clamping.jpg"><img id="BLOGGER_PHOTO_ID_5303585709452457970" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 64px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgw9kOJDuh-IWH0Vklg8VetqU7ylh1I_IghXrAj38CEe3ccLAquw9F9Dh_Dbj0mYp9-fBfZ7ZdegZem2rxHTQ5H0YPe5oGvF747E75ZqEMwKInZRH4ou2Ps6_zuXK3ar0kWE3fHI0-Ig30-/s320/clamping.jpg" border="0" /></a> Right now the two poles are clamped together hand bent to roughly the intended shape. This is as much as could be achieved with hand pressure, clamps, and carving. The back end is clamped flat to the table and some curvature induced with blocks and weights. The tips of the poles are about eight inches higher than the back ends. We can fiddle with the axletree some, but this puts our axle about 11" - 12" high and the poles about 19" high, a good hieght for a drafting dog.<br /><br /><div><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhsE418xg6t8kGQykr4tCbnRTH1hkhJTdjS3YuNCmPdEVzaF4IKJQxUzynWByBU0Tr45GDt83gtWM4h-5rE21WEYIL07m5BCphA6chipkBefrwsepeYxAhn67nnh1vEfAlYi8qF_jbOnp7W/s1600-h/cinder+block.jpg"><img id="BLOGGER_PHOTO_ID_5303585706678579826" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 245px; CURSOR: hand; HEIGHT: 320px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhsE418xg6t8kGQykr4tCbnRTH1hkhJTdjS3YuNCmPdEVzaF4IKJQxUzynWByBU0Tr45GDt83gtWM4h-5rE21WEYIL07m5BCphA6chipkBefrwsepeYxAhn67nnh1vEfAlYi8qF_jbOnp7W/s320/cinder+block.jpg" border="0" /></a> <span>Clamping like this helps the wood develop a "set" while it dries awaiting bending.

And yes, I really do dress like that in the shop when I'm working on period items (and wear the hat most of the rest of the time as well). The shirt is fustian..."as per Angus MacBride's illustrations in the Osprey Elites' on <em>The English Civil War</em>, gussetted in the neck and underarm, with 4" falling band collar and wood buttons." I picked up at Pennsic from Sykes Sutlery. I'm trying to get it that 'lived in-worked in' look. The hat was purchased from Mistress Nicola de Bracton at an "SCA garage sale."</div><br /><br /><br /><div>So I went out this afternoon (weaseled out of sheetrock taping--I <em>hate</em> taping sheetrock) and cut a small tree to experiment with for the poles. It was dying anyway, because late last summer the electric co. sprayed herbicide on it and several others. Ticked me off, bigtime. While they weren't on my lot, they were on common land next to it, and they were both waaay too short, and at the edge of the RoW, to ever threaten the power lines. Also it was covered with honeysuckle, which was also murdered. I admit honeysuckle is a weed and rank growing, but the flowers were pretty, and I like the way they smell. I hate Buckeye Rural Electric Co-op. Bastards.</div><br /><br /><div>Anyway, the clump of trees is dying and unsightly, so down they'll come--may as well serve a better cause than firewood. They're not oaks, though. I'm guessing from the bark and wood grain/color they're ash, which is common around here. I never really paid attention to their leaves, just regarded them as oversize trellis for the honeysuckle. This will work out well for the poles. I hauled it down to the shop and cut a length about nine feet long and a tad over 3" dia. at the base. The wider piece left over from the base will be a practice run for spokes, though I'm still planning on oak for those.<br /><br /></div><img id="BLOGGER_PHOTO_ID_5303217939419824930" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 240px; CURSOR: hand; HEIGHT: 320px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEilewWiBjdd7TlLRQ8DSzX1pnDMprKa5lZe7swWUrosdDSzRv9glOJ0SLK408VtavLU0jQ3TDsUe7FiDaqKk9h2vknMJRHVtqNBiKsDaZYDJ46Vzk_n2emMDHkHyzHYRoFi30K8-4HElGWM/s320/pole.jpg" border="0" /><br />I started off by removing the bark which peeled off easily in long strips (a clue to its being ash). Then I set it in the B&D workmate. Most of the time the workmate is a catchall for odds and ends, but for working long stock, especially irregular stock, it's the bee's knees (Do bees even have knees? If so, why are they considered so exemplary?).</div><br /><br /><br /><div></div><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj8UfWccOgvMJLZvGWwCuS_Olz_q9aEuyY8_8grcvVn2enr2e7j-r79McO_usoID-n0lC3dZt2vx9mpyCd24QrHcLdBzg2tzrbItUz6jPGC-5rbllLmlChuyT7gbYbBcvh5DUnsu9aWWfPE/s1600-h/drawknife.jpg"><img id="BLOGGER_PHOTO_ID_5303224065085406306" style="FLOAT: left; MARGIN: 0px 10px 10px 0px; WIDTH: 290px; CURSOR: hand; HEIGHT: 320px" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj8UfWccOgvMJLZvGWwCuS_Olz_q9aEuyY8_8grcvVn2enr2e7j-r79McO_usoID-n0lC3dZt2vx9mpyCd24QrHcLdBzg2tzrbItUz6jPGC-5rbllLmlChuyT7gbYbBcvh5DUnsu9aWWfPE/s320/drawknife.jpg" border="0" /></a>I then used the drawknife to flatten one side of the pole. </div><br /><br /><div>Let's talk about drawknives for a minute. </div><br /><br /><div>A good, sharp drawknife is a joy to use. However, a good drawknife is hard to find. There are plenty of cheap, crappy knockoffs from overseas, but one made with good quality steel is neither cheap nor easy to find. If you're a frequenter of flea markets keep your eyes peeled for old ones, which can sometimes be had cheap. This one was an xmas gift from my in-laws, and was not a flea market find--I hate to think what they must have paid for it, bless 'em. It's perfectly balanced, holds an edge like a dream, and the handles are (as Goldilocks would say) juuuust right.</div><br /><br /><div>But you have to be careful with them. My brother was using one once and he slipped: now he's my half brother! Ba-dum-bum. OK, that's an old Roy Underhill joke presented here as an <em>homage</em>.</div><br /><br /><div>The drawknife is the perfect tool for beginning the shaping on a piece of tree. Planes and jointers are great once you've shaved a side flat, but nothin' beats a drawknife, a good eye, and a steady hand for this part of the job.</div><br /><br /><div><img id="BLOGGER_PHOTO_ID_5303217930243772546" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 240px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgcEA-N5WeNkWMoW6nIxkhPQx5aLk_3l1VzdC3YGrjpv1AqlTuGdkj09O8sczP5w5P4dxAtItW_qgruKOpHY6G6JHs4tnEuSCmR_CaB0xVXnX0POyd5EZ7yB0vWvLsNIQ45aFBp88XtGkjY/s320/pole+centerline.jpg" border="0" /></div></div></div><br /><br /><div>Once a narrow flat surface was obtained running the length of the piece I drove a small finish nail in the center of the growth rings at each end and stretched a string between them. The pole isn't straight, so I'm using the natural curves of the piece to make it easier when I steam bend it to final shape. I marked a line with a sharpie along the length so I can judge where to plane off more wood.</div><br /><br /><p><img id="BLOGGER_PHOTO_ID_5303234495805167570" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 154px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhDGEQBoQ02vEefwFvr-YopNL_pZsR6UqUHtg4sGTAQFwLI3HDlZ9qz5KFWGon5SBswIWdHw61Moa2v5uzk8ikr5yHKkOHhQ3IJKy8LCvWZ-9SVj6s5TBWzBzKN09RFpqxoUCmVwAv5A3ko/s320/caliper+cropped.jpg" border="0" />Here you can see the line at the wide end of the pole. Metal calipers are massively useful for shaving wood to the right dimension. I set the jaws to about 1/2 the desired width at the base, and marked down the pole to either side of the centerline.

I then ran one of the perpendicular sides across the jointer to get a reference perpendicular edge. The pole is intended to be about 1 1/8" thick and 2.5" wide for about the first 3 feet where the bed will be, then taper to about 7/8" or 3/4" x 1" at the other end.<br /></p><br /><p>At this point I have one pole rough cut and ready for steam bending.

I've had to face the fact that I've buggered up my back so badly over the years that horseback riding has had to move into the category of 'used-to-do.' Though he's had draft training, I haven't: and it's a big and time consuming skill set to develop. Even if I had someone to teach me around here, I probably couldn't manage it, and trying to teach yourself something involving 1800 easily startled and <em>fast</em> pounds of "I'd really rather be back in the barn eating hay, thanks just the same" is definitely not smart.<br /><br /><br />So though I haven't been able to do much with him in the past few months; and logically, paying feed, vet, farrier, and stable fees for a pasture ornament--no matter how pretty--just isn't in the cards, it's still a wrench to say goodbye. He's going to a good home where he'll be spoiled rotten and played with regularly, which is important to me, but still...<br /><br /><br /><br />When I got back home I figured I'd get to work on the spokes for the dog-cart wheels... nothing like makin' sawdust to cheer a fellow up. I decided the wheel diameter should be about two feet. Why? Jest seemed right--it's one of those aesthetic things. Thus the spokes ought to be 9" between hub and felloes, which gives a wheel diameter of 9"+ 9" + 4" + 1.5" + 1.5" = 26" ( spoke length + spoke length + hub diameter + felloe thickness + felloe thickness ). Allowing for shrinkage, and tenons into the hub and wheel, meant I needed to cut and split enough oak billets to get 16 spokes (12 spokes plus 4 spares for when I screw up the tenons, count on it folks, screwing up <em>at least</em> one tenon is a given) each blank about 13" long. The length of oak I had that came down in the storm should have given me enough billets, to quarter by splitting, 20 blanks, though I figured that I'd probably only get two quarter sawn blanks from some of them due to grain run out, knots, twist, etc..<br /><br /><br />No such luck. After cutting the trunk off the stump in the cold and drizzle (the whole day it only rained while I was outside cutting, sheesh) I hauled the log down to the shop and cut 5 billets. Then I grabbed a wedge and sledge hammer and went to work splitting. I was unhappily surprised that the healthy appearing oak (it only came down because a much larger white pine further up the hillside fell over directly on it) was infested through the center with wood boring beetles.<br /><br /><br />S%*T!!!<br /><br /><br />I now have some split oak for the firewood pile and a growing concern about some big oaks near the house. Said wood pile btw being freshly delivered after the last storm when we were beginning to run low, is made up of some nice oak that I spent an afternoon cutting into smaller lengths to fit in our small woodstove, <em>all</em> of which are therefore now too short to use to make spokes.<br /><br /><br />S%*T!!!<br /><br /><br />However, I'm led to rethink splitting the spokes from billets. In discussion with a wheelwright many years back (eight and eleven twelfths, to be precise--it was on my honeymoon) who makes reproduction wagon wheels the old fashioned way as a docent in a living history museum, he mentioned that sometimes spokes were shaved down from saplings, rather than being carved from billets, in wheels intended for light use vehicles, like fer instance, dog carts.<br /><br /><br />Don't get excited--the dog carts he meant were very light, 19th century, horse drawn carts with a high seat over boxes/cages used to haul hunting dogs to the fox hunts. The thing is, I have a surplus of small oaks (less than 4" diameter). It might prove more economical of time and resources to use some of these saplings, which would also be good forestry as many of them are growing too close together and to more mature trees.<br /><br /><br />It would also make logical the construction of a springpole lathe. A drawback is, since I never bought a lathe also I never bought gouges and chisels appropriate for wood turning. IIRC Roy Underhill (a personal hero) did a show where he made a springpole lathe and the first thing he did was turn handles for gouges and make more gouges.<br /><br /><br />So it's entirely possible I may decide tonight to cut a few saplings and shave/lathe the spokes. The more I think about it the better I like the idea. For one thing, it would let me use lengths of the trees I'm going to have to cut anyway to make the poles.<br /><br /><br />I've also started working on the molds to cast pewter buckles and fittings for the harness. A dog-cart pulling harness looks just like a bridle for a horse, so I can use examples from a book on period horse tack fittings found in London--and hey, bridles I know!<br /><br /><br />So now it's off to help my Lady Wife tape sheetrock for a while...<br /><br /><br />mckMcKennahttp://www.blogger.com/profile/06500140415090961892noreply@blogger.com0tag:blogger.com,1999:blog-1426182256452590355.post-39946858643168341582009-02-13T21:38:00.007-05:002009-02-13T22:45:01.489-05:00back in the saddle again<div><div><div><div><div><div><div><div>This is me down in the McKennawerks (just kidding, I have a beard, but I really do wear a period hat like that)</div><div><br /><div><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgQxQbV2HKijhBSlW4OIcQ6RzvDBZ5mCtLwHgEWd4_59GGQIa7QbCYKannFIpBcIrh_lsv8GyCeHWyFCdSL_9sRTb9fkYllGSbuXOmz_Ae5FVNYBmI4Rsa0fwhMU_C60MofT8Pz7yqybq6x/s1600-h/shop.jpg"><img id="BLOGGER_PHOTO_ID_5302479824870003810" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 260px; CURSOR: hand; HEIGHT: 317px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgQxQbV2HKijhBSlW4OIcQ6RzvDBZ5mCtLwHgEWd4_59GGQIa7QbCYKannFIpBcIrh_lsv8GyCeHWyFCdSL_9sRTb9fkYllGSbuXOmz_Ae5FVNYBmI4Rsa0fwhMU_C60MofT8Pz7yqybq6x/s320/shop.jpg" border="0" /></a> <div>Ok, the wagon building has suffered from: </div><br /><div>1) shop waaaay to cold to work comfortably--long sleeves and power tools are not an auspicious combination. </div><div>2) every horizontal surface in the shop buried under wood and widgets. </div><div>3) sprained left elbow loading firewood. </div><br /><div>But we've had some spring-like weather, so I was able to bring a little order to the McKennawerks, and it's time to get some work done. I'm putting the finishing touches on some wheels for the "buckboard" style wagon (the bed parts are still buried). Eventually (hopefully soon) I'll get some pics and description up. But I've gotten sidetracked. </div><br /><div>A sidetrack with a deadline. </div><br /><div>As I said, at some point I'll come back to the wagon, but right now I'm into building a period dog cart for an A&S entry. Since I have to do a buncha documentation for the entry, what could be better than to blog that? Why a dog cart when I don't own a dog? Funny you should ask... I'm once again attempting a Pentathlon, and the only logical entry I have for one of the divisions is in the category of "Animal Accessories." I figure this ought to be a pretty over the top "accessory."</div><br /><div>First some commentary. This is an advanced project, and I'll be using some tools you likely won't have, I'll mention some alternative methods, and I'll be showing an alternative to a lathe for 'turning' the wheel hubs. And we'll also be (probably, possibly, maybe...) be making a spring-pole lathe at some point. And once again the plans will come last, as this is pretty much a 'figure it out as you go along' project.<br /></div><br /><div>When it comes to period dog carts we don't have a lot of information available. There are some period sources that mention using dogs as pack animals and mention dog carts, but I've only been able to discover one period illustration of a dog cart. It is reportedly in the 14th century illuminated manuscript called the Smithfield Decretals. It is on folio 110 verso of British Library Manuscript: Royal 10 e IV. Apparently this is no longer available on-line, but I have requested a copy from the British Library Image Search, and hopefully I'll have one early next week. And as I've mentioned before, we have very little in the way of extant cart or wagon parts from within our period (600 to 1600 ce). Thus we are left with the need to make logical conjectures. </div><br /><div>So let's conjecture: First, most of the construction will be in "green" (recently cut) wood. </div><br /><div>For several reasons. The first is that the wind and ice storms we had recently took down several trees near the house, so I'll be making use of a readily available material. Second, in period, most wood working was done with green wood until late in period. Green wood works easier. Using seasoned hardwood was a late period development--when tool steel that would keep an edge longer was more readily available. Thirdly, as the green wood dries out and shrinks it naturally makes the joints tighter. This is a definite advantage for the spokes and hub mortise and tenons. </div><br /><div>Forth relates to the nature of the cart itself. Who would use a dog cart? Someone with a dog. What would they use it for? Hauling moderate loads within a walking distance of their home. It seems to me unlikely that a dog cart would have been an ornate capitol investment of a wealthy landowner or noble. More likely it would be simple equipment found at a monastery or large farm, and chosen as less of a capitol investment than a large horse/ox cart or wagon. </div><br /><div>Though "Of Englishe Dogges" (1576 ce) mentions that the "Tinker Cur" was used by traveling tinkers to transport tools (and presumably goods and personal items) I think an itinerant use of a dog cart less likely, as the dog needs to be fed, and on the road this presents an expense/ difficulty that would exceed the transport value of the dog cart.</div><br /><div>So for our purposes we'll assume a monastery dog and cart.Since the iconography of dog carts is limited, it is logical to extrapolate from images of hand carts and horse or pony carts of the period. <a href="http://www.imagesonline.bl.uk/results.asp?image=021983">http://www.imagesonline.bl.uk/results.asp?image=021983</a> shows an image of a farm cart driven by a monkey from the Lutrell Psalter (circa 1325-1335 ce). If we look at this picture we see a two wheeled ladder bed cart with wattle (basket weave) sides. This will serve as our inspiration piece.</div><br /><div>I think it reasonable to assume our cart would be lightly built, and have a frame of green wood, joined with lap or dovetail joints and secured with trenails, and a wattle bed and sides. The harness would be of leather, with cast brass or pewter fittings. The value of iron would limit its use to where a suitable substitute is not readily available. Thus only the wheel hub stock rings and axle pins would be iron. </div></div><br /><br /><div><img id="BLOGGER_PHOTO_ID_5302483550348014962" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 240px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj9nASbLqnsAv5Egr5AL0gxa9eea0yKSkyFfgWd732grQFsaLVIM5CpbmBB5VvqaiSqKMAKKDwYp4OhrtnAB8u448kdx88oy8D7SQWILU-bFfkjVFEUANldgWVp0DtVHy3ANi9C0K5f9aFF/s320/hub.jpg" border="0" /><br /><div>We're going to begin with the wheel hubs.

I don't own a lathe. Weirdly enough despite all the other tools I've picked up over the years I've never gotten around to buying one. So what we're going to do is make a hub fiddle--a jig (OK, technically a fixture holds a workpiece and a jig holds a tool, we'll stick with the linguistic barbarism of calling them jigs) a jig to hold the billet centered while we use other tools to shape it. If you look at the picture you'll see it's basically two support pieces with pins clamped to a workbench.<br /><br /></div><img id="BLOGGER_PHOTO_ID_5302485271659736466" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 240px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjBwjTOzc3x-CtjupNJJ46iK33jTgxSA89ZjrPhGqeI7s5Ag0ljMLJup1At0Gtwg8LI7Av93SDKQmjZYI11cADSaVxdV_9oXZcYTPStNBvwFmuUeiN17ta4GeJdHOrfghUqfRC59U1waqP_/s320/wheel+hub+fiddle2.jpg" border="0" /><br /><div>Across the top is a slotted board to support the tools over the top dead center of the billet.<br />I used a roto zip with the routing attachment with a 3/8 straight cutting router bit to shave the rough billet into a cylinder 12 1/2" long and XX inch in diameter.<br /></div><div>I also experimented with using a dremel with a 1/4" routing bit in a jig. The dremel is mounted in part of a circle cutting jig which is attached to a simple sled to let it slide along the work bench top. This worked, and if I didn't have the rotozip I would have stuck with it but it was too darn slow.</div><br /><br /><div><img id="BLOGGER_PHOTO_ID_5302479829392889554" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 240px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhubL-anWv8gZkAa5YOdWaq6rIY5TKqX9wMslSzFs2I5ydecUQwC03s8zy7SoVUccQZ9w9rZI5vz7GJ0-_hIR5toJTS2XFNHjz66G25BqXoJ7ZOjEL9UAwuvSIK5wJ2z9WeG1tWUWGx4EGL/s320/dremel+jig.jpg" border="0" /><br />I then marked up the cylinder with reference marks to make two hubs. The hubs will be separated after the coves are cut. I'll do this on the miter saw so that I get nice square cuts.<br /></div><br /><br /><div><img id="BLOGGER_PHOTO_ID_5302479834255967954" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 240px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj8o_P29IHCQeXKGPmCtUC0rxhfc65hG0WmLuRnDxwOhX2LqCV2jGNroVk9IFWVyTPu0hFhcrmktkjzH4mUX1aKzl1zdaCBpSTIZxH1IwYJseuL2whcEVhBVtCRcOyLdjV6Lyo4OmlaK1ON/s320/marked+hub+cylinder.jpg" border="0" /><br />In order to turn the coves I used a trick usually done on the table saw, but here carefully done with a circular saw.

To do this the centers are marked with a center finding gauge and drilled in each end with forstner bit on the drill press to create a hole trough the hub for the axle.<br /><div></div><br /><div>I then made another smaller (shorter) hub fiddle and mounted a hub on a 1 1/8" poplar dowel so that it would rotate freely and slide from side to side in the jig.</div><div> </div><div><img id="BLOGGER_PHOTO_ID_5302488954218058642" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 240px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEijBX2hRQi-8sifhagTAgIDQlQ07Xpm1TvgfdUp7mxsw9g860D-zxC7REEnRjSOEeGmjwREK7G_4eHNQ7xv7GPn4dW_JdzllMxW3G_31dkPDFsmaHtEA2qHYsFvy0Pm82GfNO_so-SHTrdV/s320/Dsc04180.jpg" border="0" /></div><div> </div><div>A word about dowels... just because the label on your dowel says 1 1/8" don't expect that it will be accurate, you made need to sand the dowel smaller or the hole larger. The dowel mounting is temporary, remove it as soon as you're done working on the hub, or the hub will shrink--locking it so securely in place you'll have to drill it out.</div><div> </div><div>I mounted it to the hollow chisel mortiser. I stepped off six equal divisions with a pair of dividers then cut 1/2" x 1.5" mortises into the hubs. The sides of the mortises are parallel. Only in very heavy wagons with large wheels is it necessary to taper the sides of the mortise. In the case of these light duty dog-cart wheels the spokes will rest on shoulders above the tenons. But we do need to cut the tenons very tight because they are held in by tension only: <em>no glue</em>.</div><br /><div></div><br /><div><img id="BLOGGER_PHOTO_ID_5302488264464234034" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 240px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjlSMSaMB2mMxvL3VpNiphO15sgae6qHTG5_Srf2szfHtfIyky3XAQ2OLHuqS45rKy1_zQE6TLm8YR0i1xglpCKAerJMjFq5iHsUHEvuAtxEmonocuFGZeXBprCv6PgEAXo-eyLt4HR2LQ7/s320/wheel+hub+in+mortiser.jpg" border="0" /></div></div></div></div></div></div></div></div></div></div>Here the mortises are being carefully cut with the mortiser. The tape on the chisle shows when I've cut deep enough (about 1.5"). Cutting into oak is hard and there's no need to overdo it.<br /><p>After that it's off to the drum sander to clean them up a little. Tomorrow we'll dress up mortises and cut the spokes from more of the red oak. I'll also take some more detailed pics of the jigs.</p><p>mck</p>McKennahttp://www.blogger.com/profile/06500140415090961892noreply@blogger.com0tag:blogger.com,1999:blog-1426182256452590355.post-36781095516843270642009-01-25T20:30:00.002-05:002009-01-25T20:40:48.520-05:00Stay tunedIt's been a busy week here at McKennawerks. Since the stove died we decided to go ahead with part of the kitchen remodel in order to install the built-in oven/microwave and a new cooktop. Since I like to both be able to cook and to eat, and make coffee, that went to the head of the the to-do list. We also made a buncha progress on turning the old garage into a combination guest bedroom, laundry room, 1/2 bath, and den in time for my eldest daughter and hubbies next visit. This all involved moving a large amount of building materials from where the had been stored in the garage to the workshop. Right now my workbench and assembly table is buried under a huge pile of lumber, plumbing parts, and miscellanous "I'll just set this here for now."<br /><br />I did get a good bit done on the buckboard style bed, and made some new wheels, and I'm nearing completion on an essay about the Djebjerg and Hochdorf wagons and how to incorporate their sytles into smaller wagons. <br /><br />Anyway, I should be posting some more pics and plans soon, as well as the essay.<br /><br />So stay tuned!<br /><br />McKMcKennahttp://www.blogger.com/profile/06500140415090961892noreply@blogger.com0tag:blogger.com,1999:blog-1426182256452590355.post-88591043899998655392009-01-16T21:40:00.016-05:002009-01-17T22:07:39.499-05:00plans, page 4<div align="left"> It's been an interesting past few days here at the McKennawerks. Interesting along the lines of the ancient Chinese curse: may you live in interesting times. First the pellet stove in the workshop died--and it get's cold down there of a night, then the oven died. Lemme tell ya; disassembling an old England pellet stove is a P.I.T.A. The lower feed auger motor is fried (sigh) so it's going to be chilly in the McKennawerks for a while. On the oven front, we bought a floor demonstrator of a built in microwave/oven unit at MegaLoweMart a year ago for waaay below list that's been sitting in storage awaiting phase 3 of the kitchen remodel. So can you guess who's been installing an oven, hmmm?<br /><br /></div><div align="left">Anyway, time to get back to fun stuff.<br /><br />Some points that have occurred to me to note in the last few days.<br /><br />More concerning tires; theoretically, one could use bandsaw tires. This would require carefully cutting the wheels to fit the tire, and possibly dadoing the rim as well. I've never tried it myself, and given the cost of bandsaw tires compared to auto heater hose, don't intend to. But it is an option that would probably work.<br /><br />I was asked to clarify how to keep the wheels from coming off. In a purely philosophical sense, I'd suggest temperance, moderation, forethought, and maintaining a sense of optimism in the face of adversity. As to wagon wheels--in a typical axle/wheel assembly the wheel is held on by a hitch pin slid through a hole drilled near the end of the axlerod. In order, from side to side, is a hitch pin, fender washer, wheel hub, fender washer, axletree, fender washer, wheel hub, fender washer, and hitch pin.<br /></div><img id="BLOGGER_PHOTO_ID_5292414687767560194" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 240px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhB3XLZBjayaPR0fCsLWXKnH9LdSaohXflZk5AWSNxJ2zpIFZX7WluaM1CY_oLiOhuZMiYTotaKA2XAFu9Owv6DPkIJnBJAlA6f-3Zzg11pxVPLedTfMsSIKXiBHDWKW9POxEcMixUnZuXZ/s320/axle+hitch+pin.jpg" border="0" /> <p align="center"> Hitch pin, fender washer, outer hub<br /></p><div><div><div><div><div align="center"><img id="BLOGGER_PHOTO_ID_5292414688580030242" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 240px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhde4GdS-FU6Y-UxUSwJE2g5UL0h8_5WCcWYfSt7IjHMscd3v6_kXfOJDYRQTMireuu3JqwZPmYr84PNgiUj4fAo4njAvyHLswCSg7kfpSXJsr2Z905ebxna3Tf4pB7aq2agYkSKcQr2wcY/s320/axle_inner+hub.jpg" border="0" />Inner hub, fender washer, axletree</div><div> </div><div>Fender washers are somewhat thinner and have a smaller hole in relation to overall size than standard washers. When you assemble them all the parts should butt tightly together. You may need to add extra washers if you are off in drilling the hole in the axlerod. The way to do it is: make the axletree and wheels, the slide the axle in place, and place the washers, then mark to drill the holes.<br /></div><div> </div><div>I want to point out again, that this isn't the only way to do things. I use a variety of approaches in my wagons. Each one is different. It keeps things fresh or me. Don't be afraid to innovate when you make your wagon.<br /></div><div>I also want to again mention that <em>woodworking is craft</em>. If the parts were made from metal or plastic, fairly stable materials, and machined to close tolerances, you could just cut up all the parts and fit them together. That doesn't work with wood. Especially when you are making mortise and tenon joints. Make the parts in a logical sequence, and test and fit each piece as a you go.</div><div><br />Let's talk about how to make the wagon usable for dog drafting.<br /></div><div><br /><br /></div><div align="left"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjVdW2yjiPgL8ermSF7hzIeQB9V9Ii319UkU6VyWNgZNIK-h9Hn4qDgjxJDOhgPStZfs57wHWoEamWatmNW1YWoxyMJ2eomVZstXOQqMHCn0j62Q9FUNHKNduSPbF03FpW6LArV1GKqgMe7/s1600-h/plans+page+4+bitmap.bmp"><img id="BLOGGER_PHOTO_ID_5292088012251480130" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 315px; CURSOR: hand; HEIGHT: 400px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjVdW2yjiPgL8ermSF7hzIeQB9V9Ii319UkU6VyWNgZNIK-h9Hn4qDgjxJDOhgPStZfs57wHWoEamWatmNW1YWoxyMJ2eomVZstXOQqMHCn0j62Q9FUNHKNduSPbF03FpW6LArV1GKqgMe7/s400/plans+page+4+bitmap.bmp" border="0" /></a><br /><div align="left">Let me preface by again noting that I am not a dog person, have never drafted dogs, and have no intention of doing so. I <em>have</em> studied wagons and carts, and crawled in over, under and around many working and historical examples. I do own a draft horse (a handsome black Frisian/ Percheron cross) and have worked with draft tack. </div><br /><div>A dog cart is not appreciably different from a harness racing sulky, except for size and some of the arrangement of the traces given the different anatomy of horse and dog. I've spent the last week or so doing some extensive googling and reading on dog drafting. A reader (thank you Lady Teresa) sent me some links that hadn't come up when I googled them. There still aren't many dog cart plans out there that I was able to study: three, in fact. One is a variation of the pvc plans published several years ago (which amazingly enough I saved, and even more amazingly found where I filed them), one is a very basic wooden cart, and one is a more elaborate version very similar to a sulky, which has cold laminated bentwood parts.</div><br /><div>But it's really not a very difficult to construct, and the plans are all similar in dimensions. I'm eventually going to address how to make the traces. But if you're really into dog drafting I figure you'll already have that info, or have been to the same websites I went to. So onto how to make this puppy...<br /></div><img id="BLOGGER_PHOTO_ID_5292460499678844626" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 240px; CURSOR: hand; HEIGHT: 320px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg9tmrPYjLcWiWCQd9OT8Jhj4op2cIrujHw2H6NCs_ZaNdBArKkOVKKIfCBgg7QUHxfEiZsO4xIvzsBn5Z7tJDqRHLLBy5jjv5jZRmFFnfkrN-ZPXQ-W3yVwOR0CxoYH2ZMO7eXd-axIbtD/s320/pole+assy.jpg" border="0" />The dog drafting poles assembled to the axletree<br /><br /><br /><div align="left"><img id="BLOGGER_PHOTO_ID_5292394996327355090" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 156px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjNvYv2BCyIzbp92j_x2FJkhzCMyX0VNaXfTJWq-b485xNoDzqhGDNUJdle6ZQUqUNmqzp7AgKwY5QVMV8W_HzHSeiXl_DgxP2GOb2GS4_p0sIqvXAkL_LEYxr9n8g72ixBaOWo4z6RyNb0/s320/hounds+plan.bmp" border="0" />You'll recall we made the more decorative front axle tree. Now we're going to add in mortises for the hounds for the poles. Again, I do it this way because it breaks down for transport. You can simply attach them to the axletree with glued butt joints, and make the dowel disassemble instead. I'll show a mock up of this, too. I had the hounds already from an old project that I never went anywhere with (I never throw anything out ;-)</div><br /><img id="BLOGGER_PHOTO_ID_5292398169100678658" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 240px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjOOfuuXoKg-fq5GS6hPbcUz5ofdRpfmaZLEf47ZIX2g6CuALgCDwFX6XOepyrwaY1_W-tkZWyGe1smg1eJgIE3G8XKODi00r1krOGXq4Isc3FumVCeGxr_bxfslScCDMvJjb5LvMfHAEPC/s320/whipple+bar+and+hounds.jpg" border="0" /><br /><div>Note, this method will not work with the tongue we had used on the basic version. So we'll also need to do a tiller with hounds.</div><br /><div>If you don't have a hollow chisel mortiser there are a couple of ways to do the mortises. First is to drill out the center of the hole then trim with a chisel and file. If you have a decent sabre saw and a good blade you can also use the sabre saw to nibble out the corners after you drill the hole. If you have a table saw and clamps you can rip the axle tree, into 3 pieces, one the width of the mortise, then cut mortise-wide pieces out of the piece that's the width of the mortise and glue them back together. The glue joint; if you use titebond II or gorilla glue, is actually stronger than the surrounding wood. </div><br /><img id="BLOGGER_PHOTO_ID_5292398171738041810" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 240px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiJihT3Eklsgjx7Sa8PbV6onL2fGUUf7pU3T6RLHBveYpuFV1uAXh7f4hamu74qmdjDWQiYaiCf7LUCX-2IOMirRl-WsmoRHokZtvd2Kt8wgEyY7IsEApAE2-PTwl0ip4ofRljusLVOAe_2/s320/whipple+bar+and+hounds3.jpg" border="0" />Here we see the hounds with the crossbar installed. As I noted these were sitting around the shop. I'd suggest that when you drill the hole for the crossbar don't drill through the hound all the way. Drill the hole about one inch deep and it will hold the crossbar in place--like on your average toilet paper holder.</div><div><br />To make the hounds take a 2x2 piece of stock and trim of 1/4" of each side on the table saw to a 4" tenon with your tenoning jig ;-) Ok, I admit it, I've had a neato Delta tenoning jig for years, and I still use the router or dado blade to make tenons--but Norm would use the jig ;-)<br /><br /></div><div><img id="BLOGGER_PHOTO_ID_5292436646564687234" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 240px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiH9_vFTqP4XU03gnA9XnKU4BMiIGBc8ByBnqawNeLZJR24yqvnojrbCsBr6pJEiMzd_vgydaPVY_2y4RbLUVfY82j5zX0V_cOoaLtJ-r8vox8024QTHcK3BLamnedKC2Z0KHgWLHjiAxf1/s320/hound+wedge3.jpg" border="0" />You want the hounds about 8.5" long total, with a tenon about 4" long. The cool way to attach the tenon is to use a wedge, but I usually just drill a hole that slightly underlaps the axletree and use a piece of dowel as a wedge.</div><br /><div>To make a wedge mortise; if I really want to be fancy like when making a Glastonbury chair, I use the hollow chisel mortiser, but for wagons I go with the simpler, if not quite so meticulous method of drilling and smoothing with a dremel.<br /><br /><br /><div><br /></div><img id="BLOGGER_PHOTO_ID_5292436643973053682" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 240px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgDqGxliIE3X4DZYL9OlI_anyKB_fl0-sn5SxeCRVTITIv4ptMvaCP_cnlT2f0tuJ_uZWoQefaqf9Ywb-Kp4XPcFo_C2LIZpqR-uEaslX1s5HCrWYRIeAm4YJjEcrZD05vFEJTw_va-K6P6/s320/angle+jig3.jpg" border="0" />In order to taper the mortise for the wedge we need to make a simple jig. Cut a wedge at 15 degrees from the end of a piece of 2x4, flip it over (remember all that stuff from high school geometry about opposite interior angles :-) and set the the hound on it in the drill press and drill straight down. Then remove the wedge and finish drilling out the mortise.</div><br />Oh, yeah! <em>Very important</em> when you make the hounds mark the top and port or starboard of the hounds. You're cutting the tenons to fit the mortise, and as Justin Wilson used to say, I gar-<em>on</em>-tee that if you you've cut them with test fittings due to wood variations they'll only fit one mortise one way tightly. I suggest port and starboard rather than right and left, because if you use right or left sooner or later you'll be wondering, was it <em>my</em> right or... Make sure you cut the mortise so the taper is wider at the top.<br /><br /><div><img id="BLOGGER_PHOTO_ID_5292436648708777922" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 240px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhKbrGRYwFa8KmbJK1SOZCLpbpKy9qjwKJm7Z6_ikgmTJYPSP-rU0qmvj5YUsxCklv5Ap8_gZcUAR6NeARyW83NgPk9fd8-ssfMi2tYTdW6K4BQW1Il4qDxIyoN3WzGiO2vDGsPmItFce0P/s320/hound+wedge2.jpg" border="0" />Once you've drilled out the mortise, clean it up with a small sanding drum on the dremel. Cut the angle on the wedge to 15 degrees and round the edge to match the diameter of the drill bit. This method works best if you use a 23/64" drill bit, and a piece of 3/8" plywood for the wedge. Remember 3/8" plywood is narrower than 3/8". It fits the dremel sanding drum perfectly. This produces a nice tight mortise, tenon and wedge.<br /><br /><div><strong>The Poles</strong></div><strong></strong></div><br /><br /><div><br /><img id="BLOGGER_PHOTO_ID_5292397144158690386" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 240px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiTn2YjM5ouckdJdgMuBjkik1Fuxq5RafVKnOuZHp6Uxp187s92Xjs1QwY5mSyXCiOsoZ_Tx2zxS44AVDWjuYOKzNPcLstQwFKQJjIZB63W5OaFy6aNcx1t_JjhUu32SzbGmfLNrS29jIpW/s320/dog+drafting+poles.jpg" border="0" />The poles can be made of straight stock, say a 1x2. But with a little more work we can produce a nicely tapered set of poles. If you look at the plan you can see how to lay out the tapered rip cut on a 1x4. You can do this cut with a sabre saw, but it's very difficult to do a long rip cut with a sabre saw without a "ripple" to the cut. If you have a table saw you can do the long straight cut as a "plunge cut" with an improvised taper jig.<br /></div><img id="BLOGGER_PHOTO_ID_5292442681120117762" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 240px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiMsL2ZaGE8shLTtb0rBsQLLPuN6YzkrCJtPOnwn8BUlc2qpa6FGCnPd3Kz5g3ZjelVmC3MZHf9jWZBS-w0FgX2pQPgo8zoMOLkYajt0GBXI-B6u4MPKLsS7kyJq01636OP1ETEPn9jk3Z1/s320/dog+drafting+poles2.jpg" border="0" /><br /><div></div>To make the taper what we want to do is pass the piece we're cutting through the table saw at a diagonal. The problem is our rip fence and blade are parallel--the system is designed to keep the edges parallel. The way around this is to rip a 6" wide piece of plywood (I always seem to have lengths of luan sitting around the scrap pile) and temporarily attach the work piece to it at an angle.</div><div> </div><div>First rip the plywood strip, then move the fence in about an inch and do a plunge cut to rip a slot almost the length of the ply.</div><div><br />Then mark up the workpiece as in the plan's cutting diagram. Then line up the slot in the jig piece over the angled line on the work piece and attach them together with brads. Flip over the pieces. Use a set square to set the fence so that when you plunge the workpiece down on the blade the cut will be in the slot.<br /></div><div><br /></div><img id="BLOGGER_PHOTO_ID_5292445411695917186" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 240px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg5ozlfAs-_gKKx9E90IvMIsrEclQ1NWzR_jXXiBJ0mNLqEOUs0X46NiNz520ZuwNKEt6MmcglC80JaegbmDOWh0Ttv6PF2Yg8I7s-ZWMriKteTY1o7Xg9ROAgdvYVY7J20pyBrYv8kAXeB/s320/taper+jig.jpg" border="0" />You'll want to mark your rip fence to line up with where the blade comes up through the table so you know where to stat and stop the cut.

Attach the poles back together, one atop the other, and use the sander to match their shapes. Round the edges over. Then drill them for the crossbar. Mount them in the hounds on the crossbar and measure for the splinter bar. Cut and glue and screw the splinter bar in place. In this version I've butt jointed the splinter bar to the poles, but if I were serious about dog drafting, I'd probably go the extra step and dado the joint.<br /><br /><br /><div><br /></div><img id="BLOGGER_PHOTO_ID_5292397135744453890" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 320px; CURSOR: hand; HEIGHT: 240px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgAwd7b00D4mmS_xph2gtyYSvKENfOzWqSM1zcxlsTQJmPhTdZ4BGvN9-eExHeqplFa6mVfODqnZaChKiwMb4mNFOA3aLW6L_NfdkZ-8OH4fjUYeBVbE5Wj2TN5_AuKiJG6r6xZT0bZpSZ2/s320/dog+drafting+parts+assy.jpg" border="0" />Here we see the poles assembled to the hounds.

Johns Hopkins University Press, JSTOR URL: <<a href="http://www.jstor.org/stable/3101055">http://www.jstor.org/stable/3101055</a>> requires access agreement through an academic, corporate, or library setting).<br /><br />Ms. Boyer wished to counter the claim that pivoted axles were unknown in the medieval period. Alas, I find her argument to be mostly unconvincing. Her main premise seems to be "why would the people of the middle ages give up the use of a technology well known to the ancients, when to do so pretty well renders a wagon useless?"<br /><br />That's what I've said! And indeed it doesn't seem to make sense, but...<br /><br />We have extant ancient and roman, even late roman, examples (grave offerings) with pivot and underlock; and we have iconography of ancient and roman examples with pivot and underlock. We have no extant remains of a medieval wagon with pivot or underlock. We have no iconography that shows pivot or underlock. I am willing to concede that one of the iconographic examples she cites <em>may</em> show pivot, but again, none show underlock. Her analysis of medieval account books showing the purchase of wagon parts is (at least to me) unconvincing.<br /><br />One cannot make the claim that in a picture that is very detailed in all other aspects, when it comes to the running gear and undercarriage lacks the detail showing the pivot as 'artistic convention.'<br /><br />She also mentions the Oseberg wagon, but I have to regard this as inconclusive; and she only cites the sources that claim it was pivoted. The Oseberg remains could have a pivoting front axle, and the curved bed of the wagon would give it some underlock. But analysis over the years by undeniable experts in the field of archeology is not in agreement. The most recent analysis seems to indicate that was pegged in several places through the bolster and axletree locking them in place. <br /><br />The thought that medieval people would have abandoned such a useful technology is hard to accept, but it remains that there is no reliable evidence to the contrary that is not colored by that premise.<br /><br />I suspect that in truth they did have minimally pivoted axles, but did not use underlock. But this remains supposition, not supported fact.<br /><br />McKMcKennahttp://www.blogger.com/profile/06500140415090961892noreply@blogger.com0tag:blogger.com,1999:blog-1426182256452590355.post-58178001576340051292009-01-12T13:52:00.000-05:002009-01-12T14:01:34.697-05:00Wood movesWood moves.<br /><br />Joints in wood move.<br /><br />When we build with wood we are using a material that is inherently lacking in dimensional stability. Wood continually takes in or gives up moisture depending on temperature and humidity of the air and the piece of wood. As it does this it expands and contracts in size. Air dried wood is less stable than kiln dried, and it varies with different species , as well as with, or across, the grain and finish on the completed piece. Plywood is more dimensionally stable than boardwood, and manufactured wood like chipboard,particle board, and masonite even more so.If you go to an antique store the proprietor will tell you that the loose legs, split tops, end grain cracks, etc. are part of the charms of a handcrafted item with natural materials, so you should buy this old piece of junk that's falling apart: because flaws are charming.<br /><br />Well, perhaps "flaws" are not so charming when they're from errors, but the marks that something was handcrafted and has attained a patina of use are. Make your wagon to the best of your abilities, but don't let "the best become the enemy of the good." Don't avoid making a wagon (or any other project) just because you can't produce the equivalent of a "royal coach."<br /><br />I think it was Tage Frid who said something to the effect that the accuracy required for joinery in fine woodworking exceeds the accuracy obtainable by our measuring and marking devices. This impacts our wagon building in several ways.<br /><br />We obtain a tight and true joint by trial fitting. We cut close, then trim, file and sand closer. The beginning woodworker should cut further from the line than the experienced woodworker. Take your time.Don't expect that you will cut pieces to the exact dimensions on a plan, and poof! it magically fits perfectly. Wood isn't like that. Be aware that if you make a nice tight egg-crate joint (for example) unless you keep your wagon in a temperature and humidity controlled environment forever, sometimes the joint is going to be too tight, and sometimes it's not. I always bring a "persuader" (sometimes called a mallet) with me to events for when they're tight, and you can shim if you need to when they're loose.<br /><br />If you find that you've cut the joint too loose to start with don't worry, there are a bunch of fixes. For just a slight over-width take a piece of heavy paper wet it with glue and apply it to the side of the joint. In effect you're papier-macheing in a permanent shim. For a little bit wider error you can tack and/or epoxy in a shim of sheet metal, for an even wider joint: leather. And if it's way off the reservation cut a wood patch and glue it in place.<br /><br />As I've noted elsewhere, I like wagons that breakdown for transport, but you can glue/screw the joints if you are willing to sacrifice portability for security.<br /><br />Some other tips:<br />-- use the same ruler for all measurements and cuts, they're all just a tiny bit off from each other.<br />-- a "story stick" is a piece of wood that you mark of one measurement on to transfer it to another piece. In many cases the actual units of measure don't matter nearly as much as the relationship of the parts.<br />-- you can't cut a long perfectly straight line by hand, use jigs or fences to guide your saw<br />-- dull tools screw-up your work. Don't economize with old, worn, blades or bits.<br /><br />Most of all, when you roll up your new wagon to your friends at an event they are going to be hugely impressed and complimentary, trust me, you'll see a conglomeration of every flaw-- they'll see a wagon.<br /><br />You really can do it.<br /><br />McKMcKennahttp://www.blogger.com/profile/06500140415090961892noreply@blogger.com0tag:blogger.com,1999:blog-1426182256452590355.post-60651573651579236402009-01-11T21:59:00.000-05:002009-01-12T13:00:18.673-05:00Plans, page 3<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgyQQkqY3ejEwG_2mzMmani-riotJpF2fKEggxIZdo95rz8fdCdOY1jKnNhPV77BwqWXlH3tqK8Jd4rklDgOO-50BwtZHTWSfdu9cYkDgfe9DFintfu93wVf3VfQsiz0_LtwzebJ6G5yW0h/s1600-h/plans+page+3_1.bmp"><img id="BLOGGER_PHOTO_ID_5290468571922461698" style="DISPLAY: block; MARGIN: 0px auto 10px; WIDTH: 354px; CURSOR: hand; HEIGHT: 400px; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgyQQkqY3ejEwG_2mzMmani-riotJpF2fKEggxIZdo95rz8fdCdOY1jKnNhPV77BwqWXlH3tqK8Jd4rklDgOO-50BwtZHTWSfdu9cYkDgfe9DFintfu93wVf3VfQsiz0_LtwzebJ6G5yW0h/s400/plans+page+3_1.bmp" border="0" /></a><br /><div><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgSYSGgSNXFttaySL5-JfCAFrGCmJYEWW8Fz3QLtgL2RCZ7p8GHyMtJ3YVDlxamG5JCK1sjZTrhH-ilLJRGwiNNDjVntJqY19XUbYBo6JhLizZftih6ZHRdiLAYmNXgVfD8DOJsrBmUjYGI/s1600-h/plans+page+3.bmp"></a><br /><br /><div><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEilBNSDTNVU6-e1cSY9Wps3Oz7GiRZ-faggHBwr_J5vPLH9B7BHa60PoGPWnYJr5MYGje1TwfOkr49k_FjlAiuCBI2VyvswknOQdaxgYeMSDTiQiQkZbAJ3FH0qBbOe6C3UXubuMqLCbzAK/s1600-h/plans+page+3.bmp"></a><br /><br /><br /><div></div></div></div>McKennahttp://www.blogger.com/profile/06500140415090961892noreply@blogger.com0tag:blogger.com,1999:blog-1426182256452590355.post-59323519063838965272009-01-11T18:43:00.000-05:002009-01-11T19:43:34.936-05:00Plans, commentaryWhew! That was fun (not). It's taken me longer to do the documentation than it did to build the wagon. That's probably some sort of universal constant though...<br /><br /><br />I've gotten the plans on two pages so far. I think the type fonts work for the bitmap images and the size is adequate, with adequate detail in the plans. Next is to finish the modifications to the basic wagon, with pics, and post plans and instructions. I need to redo the materials list, too, so it's not from memory and has everything listed. Plus I just noticed the tongue and tiller aren't on the plans. Poo. Well, I've been sitting here in front of Fafnir (which just happens to be in the coldest corner in the house) for long enough. I'm going to have a hot chocolate with Bailey's Irish Cream in it and read a good book by the fire for a while.<br /><br />If you notice anything that looks like an error on the plans, or is confusing, or whatever, please drop me a line.<br /><br />McKMcKennahttp://www.blogger.com/profile/06500140415090961892noreply@blogger.com0
