Next item on Super Stearman is the plywood ribs for strut attachment. The prongs on the T Nuts split the plywhood when pressed in. I was left with nothing. I cut the ribs from a sheet of birch ply. Much better than the cheap material supplied. I would be interested in ideas for quick assemblt / disassembly for this and other bipes. Too many screws. Eight for struts. Four for lower wing; four for upper wing. There must be a better way. Any ideas?
