Tonight, I riveted the F808 and F809 bulkheads into the fuse. I was able to use the pneumatic squeezer on all of the rivets except for one on each side of each bulkhead. I used a long straight rivet set for the upper outboard rivets on the F809 bulkhead. For the F808 bulkhead, I used a double offset rivet set for the same rivets as the F809. I used duct tape to keep the double offset set from rotating in the gun. 20 rivets in 1 hour-looks like I need to pick up the pace a bit.
