Default RE: How do you sheet without gaps?

Shear webs between the spars is stronger than outside of the spars. The web's function is to maintain the separation of the spars, nothing more, so tolerances should be close on the top and bottom edges. But before people built I-beam spars, they always built box spars, and not a lot of aircraft fell out of the sky. So it's really a matter of taste, I think.

I cut a plywood template to exact size, then replicate the webs from that, for constant chord wings. For tapered wings, every space is custom fit.
