After a long break to roof my house, winterize, and move my mom.... Finally back to work. Hoping to be able to concentrate on making some progress.
With help from my son, we got the top side of the 902 spar riveted to the skin. Once again, the special bucking bar i made for this purpaose worked excellent. Next, backriveted the lower stiffeners in place and the E-615PP trim opening reinforcement. Then, riveted the counterbalance sub-assembly to the spar. Clecoed the lower skin to spar. stopped there for the day.
