Zzzzzzaaapppp!
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).

O what a tangled web we weave



The sides then followed much the same procedure. They were originally held in place by friction, but I later trenailed them to the frame. Where the cross pieces of the bed rest on the frame they are simply held down tightly by the bottom batten of the side. The pieces holing everything together at the tops of the sides are clinch-nailed with cut copper nails.
The final pieces of the bed were cross bars front and rear. These were originally tacked with long cut copper nails, but the end grain did not hold well and I eventually trenailed them with "trenails" made from wooden axles from some old 'pinewood derby' car kits. Frame
Wheels are kewl, but to make all that work practical we need to mount them to the poles and a 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.
After some work with the drawknife it was run through the planer and then squared by eye with the table saw and a little work on the jointer.
You can see the top, front and back have been squared, and the bottom (with some bark still on) shows the natural curve of the board.
A dowel from one of the hub fiddles is used to mark out where the wood will be cut away for the axles.
After cutting the waste away I was left with square axles, needless to say that is not an efficient shape, so I used the draw knife to slowly shave away the excess. The two bars on the side of the fiddle's bed are set parallel and the top is set to slightly higher than where I want the eventual diameter of the axles. The sloooowwwwww process is shave, turn the axletree a little, shave, turn, rinse and repeat.

Goodfelloes, part 2


The period wheel would have had a tenon cut on the end (you can see them clearly above) but this can be avoided in a small wagon or cart simply by controlling the depth of the mortises either by drilling or, if you've cut the mortise into the hole for the axle, placing a piece of copper or other pipe in the hole as a bearing.
Here's the jig that let's you do that. (I might add that I wouldn't consider making spoked wheels without having a good drill press handy.) The jig is made from two boards set square (checked and marked with a try-square and screwed: accuracy is critical here) and a cut off from one of the felloes. 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.

This has to square to the hub, to saw, to the dado blade, and (according to Thomas Aquinas) the universe. 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

and a combination square is used to set the distance from the tenon end to the shoulder.
On one tenon I found the shoulder too far from the end (the others all required little or no trimming).
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.
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.
After using a 1/2" round over bit and router to shaped the outer edge of the wheels I grabbed a plastic container I had lying around and marked the sides of the felloes to replicate the decorative cove. I cut these with a 45 deg. bit in a rotozip starting it as a climbing cut (with the grain) by eye. You need to be a little practiced at this or you risk the bit jerking you along and buggering up the cut, but the rotozip is a handy tool for this sort of thing.

Thank you for the compliment, John. This prompted me to go back and re-read this blog. Since last night it's had over 150 hits, so I guess there's some interest, and I'm thinking maybe I should continue it from where I left off.
I've had a lot of other irons in the fire this past year both mundane and SCA, and my irritations regarding the dog-cart and the A&S faire system have mostly simmered down, so I sorta feel up to doing this again.
Here's an older shot of the assembled cart. Since then I've added wrought iron parts for the swingle tree and hounds, and a drafting harness. We'll cover those later, for now let's get back to the wheels...

When last we'd met the wheel hubs were cut, rough shaped, and mortised and I was about ready to move on to the spokes. First, the hubs.
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 shipwrighting checks were filled with oakum/pine tar. Not having any oakum, and not liking the stickiness of pine tar, I went with this.
The mortises were labeled with roman numerals for the starboard hub and letters for the port. This is essential 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.


Once this was done the tenons were cut on the opposite end using the dado head on the table saw. These were all cut slightly oversize to the intended mortise and marked to orientation on the hub as well as the intended mortise hole.

The Deacon's Masterpiece, or the Wonderful One-Hoss Shay

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.
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. Enjoy...
HAVE you heard of the wonderful one-hoss-shay,That was built in such a logical way
It ran a hundred years to a day,
And then, of a sudden, it--ah, but stay
I'll tell you what happened without delay,
Scaring the parson into fits,
Frightening people out of their wits,
--Have you ever heard of that, I say?
Seventeen hundred and fifty-five,
Georgius Secundus was then alive,
--Snuffy old drone from the German hive;
That was the year when Lisbon-town
Saw the earth open and gulp her down,
And Braddock's army was done so brown,
Left without a scalp to its crown.
It was on the terrible earthquake-day
That the Deacon finished the one-hoss-shay.
Now in building of chaises, I tell you what,
There is always somewhere a weakest spot,
--In hub, tire, felloe, in spring or thill,
In panel, or crossbar, or floor, or sill,
In screw, bolt, thoroughbrace,--lurking still,
Find it somewhere you must and will,--
Above or below, or within or without,--
And that's the reason, beyond a doubt,
A chaise breaks down, but doesn't wear out.
But the Deacon swore (as Deacons do),
With an "I dew vum," or an "I tell yeou,"
He would build one shay to beat the taown
'n' the keounty 'n' all the kentry raoun';
It should be so built that it couldn' break daown!
--"Fur," said the Deacon, "t's mighty plain
Thut the weakes' place mus' stan' the strain;
'n' the way t' fix it, uz I maintain,
Is only jest
T' make that place uz strong uz the rest."
So the Deacon inquired of the village folk
Where he could find the strongest oak,
That couldn't be split nor bent nor broke,
--That was for spokes and floor and sills;
He sent for lancewood to make the thills;
The crossbars were ash, from the straightest trees,
The panels of whitewood, that cuts like cheese,
But lasts like iron for things like these;
The hubs of logs from the "Settler's ellum,"
Last of its timber,--they couldn't sell 'em,
Never an axe had seen their chips,
And the wedges flew from between their lips
Their blunt ends frizzled like celery-tips;
Step and prop-iron, bolt and screw,
Spring, tire, axle, and linchpin too,
Steel of the finest, bright and blue;
Thoroughbrace bison-skin, thick and wide;
Boot, top, dasher, from tough old hide
Found in the pit when the tanner died.
That was the way he "put her through."
"There!" said the Deacon, "naow she'll dew."
Do! I tell you, I rather guess
She was a wonder, and nothing less!
Colts grew horses, beards turned gray,
Deacon and deaconess dropped away,
Children and grandchildren--where were they?
But there stood the stout old one-hoss-shay
As fresh as on Lisbon-earthquake-day!
EIGHTEEN HUNDRED;--it came and found
The Deacon's Masterpiece strong and sound.
Eighteen hundred increased by ten;
--"Hahnsum kerridge" they called it then.
Eighteen hundred and twenty came;
--Running as usual; much the same.
Thirty and forty at last arrive,
And then come fifty, and FIFTY-FIVE.
Little of all we value here
Wakes on the morn of its hundredth year
Without both feeling and looking queer.
In fact, there's nothing that keeps its youth
So far as I know, but a tree and truth.
(This is a moral that runs at large;
Take it.--You 're welcome.--No extra charge.)
FIRST OF NOVEMBER,--the Earthquake-day.
--There are traces of age in the one-hoss-shay--
A general flavor of mild decay,
But nothing local, as one may say.
There couldn't be,--for the Deacon's art,
Had made it so like in every part,
That there wasn't a chance for one to start.
For the wheels were just as strong as the thills,
And the floor was just as strong as the sills,
And the panels just as strong as the floor,
And the whippletree neither less nor more,
And the back-crossbar as strong as the fore,
And spring and axle and hub encore,
And yet, as a whole, it is past a doubt
In another hour it will be worn out!
First of November, 'Fifty-five!
This morning the parson takes a drive.
Now, small boys, get out of the way!
Here comes the wonderful one-hoss-shay,
Drawn by a rat-tailed, ewe-necked bay.
"Huddup!" said the parson. --Off went they.
The parson was working his Sunday's text,
--Had got to fifthly, and stopped perplexed
At what the--Moses--was coming next.
All at once the horse stood still,
Close by the meet'n'-house on the hill--
First a shiver, and then a thrill,
Then something decidedly like a spill,
--And the parson was sitting upon a rock,
At half-past nine by the meet'n'-house clock,
--Just the hour of the Earthquake shock!
What do you think the parson found,
When he got up and stared around?
The poor old chaise in a heap or mound,
As if it had been to the mill and ground!
You see, of course, if you’re not a dunce,
How it went to pieces all at once,
--All at once, and nothing first,--
Just as bubbles do when they burst.
End of the wonderful one-hoss-shay.
Logic is logic. That's all I say.

I'm baaa-aack
Not.
I swear remodeling looks soooo easy on the DIY shows. 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.
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.
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 at least 3 grand, new." Despite my impeccable logic Gen went off to ask the manager how much. His response was, "If you promise not to bring it, back how does $500 sound?" Score!
Of course, even with 10' ceilings it was too tall, so emergency crash remodel project # 473 rip out 16' steel garage door, frame new opening, and reframe rafters to install a cathedral ceiling to clear the 11.5' palladian window. The decision was made to go with a "morrocan" decorating theme, and in fits and starts we've added storage, a raised section of floor enclosed for a laundry room and half bath, installed a wood burning stove, new wiring, new high "E" windows, ad exhausteum.
But now we've finally gotten close enough to finishing that Gen has declared that she wants one room totally, completely, absolutely, done -- or I walk the plank.
Anyway, to save life and limb I've been putting a lot of time into finishing the "Peacock Room," named for the subject of a huge beautiful stained glass window I brought back from Tijuana. In the course of the last month, between trying to get the dog-cart ready for Kingdom A&S I've been plumbing, wiring, installing track lighting, painting, taping sheetrock, and getting ready to venetian plaster the ceiling preparatory to tiling the floor (the tile has been 'aging' gracefully in storage since about a month after we bought the house--it was on sale at another Lowe's closing sale for about 10 cents/sq.ft.).
On the dog-cart project, much was done, but until about the last 9 days much of it was "more of the same." The second side pole was cut, shaped, steamed, and fortunately didn't split, the wheel hubs dressed, and parts cut for later assembly. Then once laundry room mostly done, and with deadlines fast approaching I declared that since the washer and dryer were once again working I was off to the McKennawerks--hold my calls.
After a marathon of flying sawdust I had only the paperwork left to do, and at the last minute the #&^$ing computer swallowed my file folder of documentation without a burp. S*%#!
Despite having to hand write something totally inadequate on the drive up, and printing out a copy of the blog to this point, I managed a second, so it's on to Kingdom A&S in May, even though the pent went down the toilet.Now that I can finally breathe again, it's time to transfer all the pics from the camera to the computer, and catch this thing back up. This would be a lot easier if I could touch-type...
Rather than one reaaallly long post that will take me a week to write, tomorrow I'm going to start posting a buncha small, probably disjointed, entries.
See ya,

A person sized cart
King Edward the Confessor giving alms to a leper in a cart. A 1517 woodcut by Hans Burgkmair (1473-1531), part of a series of images of diverse saints done for a commission by Emperor Maximilian I .
One of the points of discussion around small wagons and carts being used to haul small loads and kids around SCA events is: would it have been done in period? 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.
