I still had maybe 9 or 10 remaining rivets to do in the very leading edge of the tank. The awkward angle of bucking and using the gun when the tank was in the vertical position meant that I bent over the shop heads more often than not, which is why I got help on the previous tank. I'm impatient though, so instead of waiting for help, I figured I'd give it another shot myself. This time I took the tank out of the jig and tried riveting with it just laying flat on the table. This allowed me to hold the rivet gun much more normally. Reaching around and into the nose with my bucking hand was just on the edge of physical limits, but in the end it actually worked out great. I was able to finish up all of the rivets just fine. I wish I had tried this approach on the last tank! Oh well, next plane I guess. Tomorrow I will seal all of the rivet heads and should be able to get all of the plumbing finished up.
