Now that all of the rivets along the longerons are set, the F-711D angle could be riveted to the F-711 bulkhead. I managed to get a squeezer on these.
I positioned and drilled/reamed the seatbelt anchors just in front of F-708. I also reamed the 1/4″ holes in the front for the bolts that attach the cable.
After drilling the F-728 angle to F-706, I riveted the reinforcing angle in place. I was able to squeeze one of the rivets that attach F-728 to F-706 at the top.
I was also able to squeeze the upper four rivets that attach the lower end.
