I riveted on the rudder skins except for the back two on each side of the top rib and one on each side of the bottom rib. These areas are too narrow to be able to use the rivet squeezer. I will try to back-rivet them using a thin bucking bar but if that dosen't work I will just use pop rivets. I had to use pop rivets on either side of the rudder brace as I was unable to get a squeezer to reach. The platenut was in the way.
