R. Elevator-riveted the 704 tip rib to yhe 703 counterbalance rib. I installed a nutplate near the end of the tip rib so that I could easily add a bolt with some washers if I needed additional weight to balance the elevator. Probably won’t need it, but easier to add now rather than later. Then moved to the other end and riveted the rudder horn to the root rib and spar. Used my pneumatic squeezer for all 26 rivets.
