Final fitting of the F-7112 Aft top skin - 5 hours

Started the build session by messing with the fluting on the F-706 bulkhead and now I have a great fit. With all holes nicely cleco'd I match drilled everything (with the exception of the holes along the longeron. I'll do those later).

I am not ready to fit the F-656 gusset plates. Using the same method as before, I clamped everything in place.




Once the #30 holes for the gusset plates are set, I was ready to partially un-cleco the top skin to access the F-707B angle. I drilled the angle, and then noticed that the fit isn't as nice as I would like it to be. I'll have to re-do this part.

To finish off the evening, I riveted the gussets to the longeron and bulkhead.
