Finished attaching the ribs and hinges to both spars, As it turned out I was able to squeeze all of the rivets, nd I went rather quickly.I Clecoed the Nose skins onto the Left Flap in place, Clecoed the Top skin inplace and then experimented with ways to try and buck the rivets, with one hand in a cast. Piece of cake! got all of the Left Top skin and 1/2 of the Right top skin riveted to spar and to ribs. I found that with the 4" no-nose" squeezer head that I was able to squeeze the last 2 rib rivets and didn't need to do the back rivet routine. Clecoed in the Left bottom skin, and found out that I'm going to need some help bucking these, as there is no way that I can fit my hand with the splint/cast between the skins.
using 4" no-nose squeezed all of the AN470 4-4 rivets
