Finished Clecoing Aft Fuselage
A short night tonight – I finished clecoing the aft fuselage togther which basically involved adding the F-706, F-710, F-711 and F-712 Bulkheads to the assembly as well as the bottom tail skin.
The F-706 Bulkhead is a bit awkward to deal with, and it fit snugger than I thought it would, but by starting at the bottom middle and working my way up each side, I was able to insert the clecos without issue.
Here is the F-710 clecoed into place. This thing is a real pain in the buttocks to get into place. While the picture show the F-711 and F-712 behind, don't put them in until after you have installed the F-710 as you will need to flex the skins and j stiffeners a bunch to be able to fit the F-710, and you won't be able to if the F-711 and F-712 are installed. My other suggestion would be to install the F-710 before you install the tail skin, you'll just have to slide the tail skin in between the F-710 and bottom skin so don't cleco it to the bottom skin yet.
You almost need an extra set of hands to get this done, but it is possible. I slid the F-779 Tail Bottom Skin between the side skins and between the F-710 bulkhead and bottom skin. Next, I slid the F-711 bulkhead assembly, flexing the j-stiffeners as needed, followed by the F-712.
The fit on some of these tail parts is horrible. It may be hard to see in the picture, but the holes on one side of the F-711B bulkhead do not line up with the holes in the skin, they aren't even close. I've done all the flanging I can, so I am not sure what else I can do here. I'm going to have to research this a bit.
Here is the same area from a different angle.
