Torqued the four bolts top and bottom tie down bracket bolts on the LH spar. Applied torque stripes.
Clecoed the LH leading edge in place on the LH spar. Riveted the three center rivets on the inboard most rib. The shop heads were acceptable but the factory heads were deformed and it appears that the rivet set didn't sit properly on the rivet. Drilled out the center rivet which was the worst and called it a night.
I might try a long straight rivet set instead of the offset rivet set I was using. Another option is to use blind rivets.
