Brian and I riveted the rear spar. We first practiced squeezing the 4/32 round headed rivets with the rivet squeezer, but they had a tendency to bend rather than flatten evenly. Then we had trouble getting the spar into the rivet squeezer. We finally bit the bullet and pulled out the rivet gun and bucking bar. After practicing a few rivets on some scrap, we riveted the rear spar. All of the rivets came out fine.
