Anyone interested in 83 Pace Arrow Tear down and Rebuild?

So, after gluing those 4 pieces back together, I glued 1/8 inch plywood to the top and bottom of the assembly. So, we are back to about a 6 x 6 inch stack of blue board insulation, sandwiched between 2 thin pieces of plywood, again supported about 30 inches apart.

This was only cheap stuff from one of the box stores, and nothing special. Just a piece I had laying around.

I stepped on it, and nothing happened. Oh, it bowed very slightly in the center, but not much. So, the plywood sandwich made a huge difference.
