I'm going to order plywood soon for my bipes leading edges.


I'm substituting for aluminum leading edges, have a nose stringer and the spars are massive...so its more about cosmetics and durability that lead me to wood, not adding strength(over alum).


Peter Garners replica posts have me interested in using 1mm ply instead of 1.5m(1/16"). It seems like there would be a good weight advantage...i'd be using about 9.5 sq ft. of ply.Also it seems it would be more easily formed.


My only hesitation is if it would have any tendency to sag between nose ribs if too far apart? or will itbe superior to a standard aluminum LE in that respect also?
