If it only fit on 10' :thinking:


I'm not quite sure what you mean, but those files are for a cabin that fits on a 10' long frame. But cut from 8' sheets of plywood.

Those files are for a 126" long cabin cut on an 8' table (The rear curls back into 10'). The skeleton is joined by a spline joint.

And the joint is sheathed over with the skins.

One last question on this topic: is there a benefit to using 1/8" ply over the roof insulation before skinning in aluminum? Given the spars and loading directions, it seems like you don't need the additional strength that you get from sandwiching the walls.


My roof systems start out with an 1/8" Baltic birch headliner, 2" spars and 2" of foam board, topped off with another layer of 1/8" Baltic. It's all glued together of course and the system becomes a torsion box just like the walls (but stronger since it's 2-1/4" thick).

It's stiff. I could probably stand on it. :frightened: But without that top layer, it wouldn't be nearly as strong.
