Subject: Re: Pietenpol-List: Re: wing const. knots to itI covered my root ribs the same way with plywood so that it would be easier to attach the fabric. Knowing that the fabric would pull on the ribs, I also attached 2 inch wide plywood to the undersurface of the root ribs. After tautening, it still bowed in nearly 1/2 inch.Jim Malley________________________________________________________________________________Date: Wed, 3 Nov 1999 19:31:08 -0500Subject: Re: Pietenpol-List: scallop leading edge ply?

It will pull down a little between the ribs as the fabric shrinks and give you a nice transition. Larry >>I did it the way the plans call for, but was concerned that scalloped ply might have been the better way. It turned just the way Mr. Pietenpol said it would, and I'm very pleased with it. However, I did bevel the top aft corner of the plywood just a little, so the fabric could roll off of it, as opposed to a sharp break.Chuck G.________________________________________________________________________________
