Brief Description: Riveted Counterbalance Rib and Skin
Riveted the R-912 counterbalance rib to the R-902 spar. Then riveted the R-913 counterbalance skin to the counterbalance rib. Also installed the counterweight after trimming it in a few spots so the rivets could clear it. I was able to squeeze all the rivets using my four inch no hole yoke.
