Brief Description: Floor nutplates, seat back hinges and footwells
I got to use my Avery's bucking bar that has the dimple die hole in the end of it. I installed the AN470 cupped rivet die in the bucking bar and clamped it in the vise - it worked great for back riveting the AN470 rivets thru the hinge / floor/ stiffeners. I tried to show you the setup in Pic #1, but I was holding the camera in one hand and the rivet gun in the other to give you an idea of how it works - obviously missing from the picture is the floor/hinge/stiffener.
I then back riveted some more stiffeners on the front floor, back riveted some nutplates into the floors and the backriveted the footwells together.
