Riveted the right side brackets to the rear HS spar and also riveted the HS skin to the nested doubler and rear spar where I removed rivets to complete the SB. Deburred and primed the repair doubler, nested doubler and new brackets for the left elevator outboard hinge. Dimpled the nested doubler with the squeezer which worked much better than my modified #40 vice grips. Installed/clecoed in place the repair doubler and nested doubler with the bent hanger tool. I used it to slide the repair doubler between the skin and rear spar and pulled it in behind the rear HS spar. That little tool worked great too to blindly install the repair doubler. Painted the brackets to install tomorrow and finish this SB.
