Flipped the tailcone around and got the bulkhead rivets on the right skin done. Started to proceed with rivets on the aft bottom skin and the rudder stop braces.
I realized I had installed the rudder stop brace F-1056 upside down and it was not aligning correctly with the rudder stop stiffeners F-1055. Had to drill out the four flush rivets in the aft bulkhead assembly and redo them. It could have been a lot worse. Was able to get them with the gun, although I did have to drill them out several times to get them to sit perfectly flush.
Almost done with this section. Just need to get the rivets in the bottom radius done. I tried to back-rivet those myself but they came out terrible. Could t maintain a rotation of the cone against the back plate that would keep those flush. I will try to do them with the wife holding the big bucking bar.
