Jon, I use 1/8" aircraft ply (birch facings and at least 5 plies, 7 is 
better, stiffer). Lite ply could also be used but the 1/8" would need doubling up 
and would be a little heavier. It isn't necessary to use the more exotic 
material like end grain balsa with carbon cloth facings but if you have this stuff 
laying around, it will also work well. You will need ply circles where the blind 
nuts will be inserted, to reinforce the area. 

The all around best solution is the 1/8" a/c ply.
