Hello KR net members, I would like to add one question to what Dubi Gefen is asking. It relates to what he calls step 1. Sanding the foam. With the thicker spars of the new airfoil is it possible to put relief cuts into the structure of the wing, both foam and wood, so that when all the plies are in place the finished surface is one constant glass layer thickness above the airfoil and will require less filling before finishing/sanding?
Reference is "MOLDLESS COMPOSITE HOMEBUILT SANDWICH AIRCRAFT CONSTRUCTION, 3rd edition-September, 1983 page 3-9 step 3: Prepare Surfaces the third paragraph.
