Started riveting the rear spar on the right wing, since it was still on the workbench from attaching the ribs to the spar. Most of these rivets I could get with the squeezer. I have a longeron yoke that fits by big squeeze that works great for reaching around the flange. I went ahead and put the factor head on the rear spar, since I was thinking that would be more visible, but I think it would have pulled the rib flange tighter if the factory head was on the inside (shop head on the aft side). The thinner rib flange tends to distort as the rivet is set on the shop head side. I had to switch the direction for the aileron brackets, since there isn’t enough room for the squeezer or rivet gun to place the factory head on the aft side. This worked great using my small bucking bar.
