Finished the J-channels today

Finished the J-channels today…woohoo!

The next step in the plans was to start bending the longerons. I really didn’t feel like messing with that yet, so I clecoed the F-711 and F-712 bulkheads in place on the F-779 lower tailcone skin.

The fit of these parts is notoriously bad, and I’d read a lot of gripes about this area on the usual websites. Those tabs on the bulkheads have to be bent correctly to match the angle of the F-779 skin, and the skin itself is very thick (0.040″) so it requires some wrestling to get several of those clecoes in place.

Once I started looking at this area and how the tailwheel mount fits between the F-711 and F-712, I realized that there are a couple of rivets in the F-712 that shoudln’t have been done yet…so I get to drill them out.
