 |
|
Greetings -7 fuselage builders,
I've got a glitch with my F-770 forward side skins. With the mid section
belly skin clecoed to the tailcone (at) F706, when I add the F770 side
skins & cleco them to the F704, 705 & 706 bulkheads I get a 'pucker' in
the bottom edge of the skin between the rear spar carry-through & the
change in angle of the bottom skin where the F-770 curved portion
starts. This is where the 770 would (I assume) get riveted to the flange
of the F-623 rib that lies flat in the belly skin on each side.
Both sides do this. I've removed one skin & rolled the bottom corner to
fit the tailcone, & it still has the 'pucker'. With the 770 clecoed to
F705 bulkhead there is about a 1/4" gap at midpoint between the rear
spar & the point at which the curved transistion begins.
Again, one side has been curved to transition around to the belly & the
other is still unbent; both exhibit the same bulge.
Related question: I see in my instructions one note that says 'don't
install the F-623 ribs now' but I can't find any instruction to actually
install them. Anyone seen that instruction? All I've seen is an
instruction to install the forward doubler attach tab for the F-623's.
Thanks,
Charlie
