The first photo will tell the average, astute RV builder an interesting story. Yes, those are 1/8" clecos in the skin, flap brace, and flap hinge. Yes, they should be 3/32" clecos. How did I fit those big copper clecos in those tiny 3/32" holes, you ask? Somehow, in the drilling of the flap brace, I apparently used a #30 drill bit. I didn't notice it until today.
My solution is to use MS1097 "oops" rivets in all 45 holes that fasten the flap hinge on. I drilled out the hinge and the skin to the larger size, then clecoed everything together to make sure it all looks good. It does. Nobody will ever know the difference except me and you. ;-)
I cut the hinge pin in two and made the first of two or three bends that will position the free ends where I can safety them to the flap brace. (By the way, I have found that hinge pins can easily be bent in a bending brake. It makes a nice small radius, and leaves no stress marks or gouges in the pin.)
