Subject: Pietenpol-List: Rib Varnishing and CoveringPieters,Having read the list for the last few days I'm wondering if some of you are glueing your fabric to the ribs in addition to stiching. My advisor has talked about it concerning the Piet and it's unique airfoil. We plan only to glue on leading edge, wing tip bow and trailing edge (alum) plus the roots and aeliron wells. I mentioned the cautions I'd read on this list about incompatibilities of 1 and 2 part varnishes and adhesitives. He sort of brushed it off by saying it will make the fabic stick better. I accept his judgement.Also, concerning the leading edge underside. He felt that due to the under curve aft of the front spar, and that there was no solid curve under as was on top of the nose that a piece of 1/4 cap strip between the ribs on the front spar might help the airfoil keep from over scalloping on the under side. Would like any comments on these subjects. I've not had my naked inspection yet as I continue to change things daily. I might change the name of that inspection to " my short-arm inspection" I wonder if any out there in the Piet world could identify with that.Corky, down at the Infirmary trying to convince the medics that the only place I've been with my pants down was the latrine.
