Two questions, I used the "circle method" but the 1/4 circles forward of the spar don't cover the cap strip completely (using a 2 1/2 dia. circle). Is this an issue? Secondly, and this makes the first question redundant, the Steen manual recommends that he gussets forward and aft of the spars be made out of a single piece of ply-how wide? Does anyone have a photo of a built up rib with these changes?
