Subject: Pietenpol-List: Centersection David,For what it is worth and without better instruction or advice, this is what I did on that center section problem.First. I dress all four main wing spars to 3/4 thickness. Added 1/8 birch plates. This gave me a 1 inch overall thickness. Bolted my steel straps.Second. I dressed the centersection spars to .715 . Added 1/16 mah plates and bolted the strapfittingsin place. On the triangular surface below the strap I cut and ffitted a3/32 piece of plywood. I sanded this piece smooth with the 1/16 surface to fit under the cabane fitting. So, lets add: Spar .715 + .160 (2 .080 Straps) = .875 + 2 plates of 1/16 plywood .125 = 1 inch. This allows the centersection fitting with bushing welded in to mate with the wing fitting perfectly.CONFUSED? So am I just trying to put this down in print. I hope my procedure works and holds this bird together. I or my widow will inform the list.Corky in electrified La after 8 days. But my welding has sure improved________________________________________________________________________________
