The day started out by match-drilling the two holes on the hinge brackets at the bottom of the spar. This was followed up by counter-sinking the spar-doubler and dimpling the spar. I touched the new holes up with the Napa #7220 primer. The flush rivets (front side) at the bottom of the spar were done next by using the back-riveting plate. The standard rivets were then set. The ribs were attached to the front spar, then the skin was clecoed on then riveted. Finally, the rear spar was clecoed, then riveted. A very good day!
