Re: Fuselage gussets

Full-size sheets, 4’ x 8’ which were then cut down for me into 2’ x 8’ for shipping. I Purchased two 1/16 inch sheets one 1/8 sheet and one 5/16 inch sheet to the best of my recollection. They were actually in metric sizes but the measurements I gave are pretty close.

Re: New here, with question

Guys, Even if you remove the engine and junk it — which I’m not implying, the airframe alone could be worth the asking price! Figure around $2000. For wood, $1500 for covering, $800 for paint, and around $500 just for turnbuckles, and that's just the structure. Add instruments, gas tank, seats, stic...

Re: Fittings: annealing, bending, hardening?

Another item regarding metal work, is to draw file edges and then sand smooth with emery cloth to eliminate ALL defects on edges of piece, as these, too, will create create crack propagation points.

This type of prep must be done prior to bending.
