27, 2005) at 09/28/2005 09:15:10 AMSantiago,I build my first aileron Rib with a 1/4 inch gap, used 1/4 ply as spacer.But this pace quickly disappears when fabric is applied, this area sees atleast three layers or more due to folding and overlaps of the fabric.My gap is now less than 1/16, it works, but if I had known I would havestarted with 1/2 inch or perhaps 3/8.RegardsHans________________________________________________________________________________Date: Wed, 28 Sep 2005 06:59:45 -0700 (PDT)
