See the bottom wing former........gotta figure a way to bend/twist the plywood without breaking it so I can fasten it down to b3,4,&5. Easy enough to do with a 3/32 piece of balsa, but a bit tricky with 1/4" plywood. Maybe get the steam kettle out and hold it under where I need to flex.

You might try kerfing the inner portion, cutting a series of vertical slots on the back side, about 3/4 of the way through. Enough slots will allow the wood to flex so you can manipulate it into position.

Kerfing might work, but with only a 3 lam plywood, you'd probably have to dampen the kerfed side also as the graining in a hem or doug fir veneer is pretty rigid at the color variations and a stepped effect might occur at the glue points. I would have cut the ply cross grain and it probably wouldve bent much easier, No kerfing just moisten the backside, apply CA and clamp.
