WOW Sqeak, what have you got me into? (Hehe)

After measuring distances between ribs, I found they vary anywhere between 3.227 to 3.552. There are 38 bays to address if I do them all. (and I probably will) Fortunately, I have enough 4" stock here in the shop. I'll just trim close to 1/2" off each sheet prior to cutting individual pieces. Another thing to compensate for is the small fillet of glue at each joint. I'm sure you want the webs to fit flat against the spars and also tight against the ribs.

Oh well, here goes!
