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.
