Quoting myself from
this thread:
Quote:
Consider plywood for the ribs and cedar for the skin. A friend of my[sic] built a egg-shaped house on a Ford flatbed truck back in the 70s. He made plywood ribs, ran light wood stringers and shingled the whole thing. When it was done he had it sprayed out inside with polyurethane foam. What was a wobbly structure turned into a solid block of foam with the shingles embedded in the outer surface.
Where he shingled it vertically like a stationary house, you could turn the shingles 90° so they lay like fish scales.

Edit: He laborously hand tapered each shingle to fit. If I was suggesting it today (as I had then), I'd go for beveling each shingle[s thick edge], hot-melt gluing each one and using a geometry more like this:
Frameless!
