Ya got to think he built about 10 full size WW1 planes so parts count never crossed his mind.
Everyone! KNOWS the S/S for these common woods! (Glovers Pocket Ref, at most hardware stores) My own experence has been in laminating multipe thin veneer in epoxy into highly stressed, very light weight, compound shapes. (Ocean racing sailboats) Ever vacuum bag a 60 footer? Stresses in these hulls often exceeds those found in the aircraft we own. You might do yourself well to spend some time at the hangars in lieu of the forums. "Experiece starts when you begin"!

What if you just molded thin layers of ply and little strings of carbon in between into strategic places to give more strenght to it ? Lets say like in between a 0.8 mm thick ply youd run in every 100 mm:s a 2x0,8 mm string and the 98 mm 0,8 mm ply string in between..sides glued in pressure with epoxy..this would make the ply really really stiff.
You could then put the formers/foils 2x further than before with same or more strenght.
How many times do we need to talk about materials like plywood and carbon being incompatible. So you put a carbon strip in the inner layer in plywood. The only thing it could add is tensile strength. Tensile loads are stable in buckling. So what is the plywood doing? Adding weight? Plywood is a good material on it's own and the intent of Orion's design exercise was to use one material and one machine (laser) to take lots of labor and inaccurate hand cuts out of the equation. Making your own plywood and introducing composites doesn't walk away from the goal, it sort or runs away screaming incoherently.
I guess so. It could also be just 1/2 as thick ; 3 x 0.4 mm...thus very lite.
