Discussion with ZAC engr. regarding "edge distance" with 1 1/2" hinge supplied for flaps. ZAC person says the hinge is correct, I said it isn't. He wants me to add second row of rivets...lousy answer. This picture was sent back to explain the correct dim. should be 10 mm ... he says 8 mm.That would make edge distance about 2-3 mm. ???I suggested he send me a 2" flap hinge. This would give the proper edge distance after riveting.I ended up ordering 2" hinge material, at my expense. This guy is an idiot.Made a drill gauge for nutplates for inspection covers.Rivet squeezer from ATS on backorder.Pop rivet dimpler needs nails.
