Here's my last sequence of closing out the tailcone and fin attach. With the FUS22 triangles in place, it was time to bring in FUS30 and its doubler. I started by getting FUS49 (tailwheel attach bulkhead) riveted into FUS30. Then brought this unit over to the last bulkhead on the fuselage (FUS36) and riveted it in place there, making sure everything got squeezed together before riveting. That left me with FUS31 to insert (image 1). Once inserted, I riveted the forward rivets and the triangular gussets. Then I slid in the fin and clecoed the front fin attach bracket to the FUS36 doubler, and got the tailwheel attach brackets bolted and torqued to the aft section of FUS30 (just under left hand in image 2). Then riveted the fin attach front bracket and finished off the CS rivets along FUS31 and regular rivets along the fin spar. Completed the FUS30 doubler X-pattern of rivets and tada: completed tailcone! Last shot shows a nice flush fin attach to the bulkhead.
