RE: Palmer B-25 Build
Next set of pictures. the main spars in picture 3 are cut from 1/16" ply. Since I can't leave my planes on the building board (no room), I took a small metal bar that hangs the plane vertical by the crutch, keeping it straight. I'll use it, until all the stringers are in place. Once in place, the fuse should stay straight, and I can work on it on my building board.
