Drilling the last hole through HS-405(rib) to HS-702(forward spar) to HS-710.
I was using the pilot hole in HS-405 rib, but either that was a bit off or my drill was a bit angled or both. In any case, my edge clearance on the HS-710 angle stock is less than 2xDia. This takes a AD4 rivet (dia. 0.125) so the center of the hole at 2D should be at least 0.250 from the edge and the lip of the hole should be at least 0.188 from the edge. This hole is .053 too close, argh!
I'll call Van's on Monday, but probably will need to buy all three parts new for my first "redo".
I'm assuming that the 2D edge clearance is a MUST and does not depend on the thickness of the material? (HS-710 is not sheet metal, does this help me?)
