Continued with making the doubler for the tab where the edge distance was insufficient, then riveted the right hand rudder stop in place, again using the AN470 rivets. After that, I continued with riveting the front side of the F712 bulkhead, and started on the F711. This is slow work, you need an extra elbow in each arm to reach over the top of the tub to buck the rivet, and drive from the bottom. Then when you are ready to squeeze the trigger, the gun moves and the rivet falls out, and you have to start over. A real pita. Think I will slack off until I can get a rivet helper over one night this week.
