Used the squeezer to rivet the skin to the F-715 ribs as far as I could. Then used the squeezer to rivet the center F-772B floor stiffeners to the firewall angle. Was able to squeeze two rivets on the floor stiffeners to the F-783 cover support ribs, but the aft most rivet had to be done with the gun, with offset, and bucking bar. Also had to put the rivet in the "wrong" way (factory head on thicker side) to gain access for the gun. Used the gun and bucking bar to begin riveting the F-713 auxiliary longeron to the skin on the left and right side. Started at the F-704 and went forward to the F-902 bulkhead.
