With the mid section belly skin clecoed to the tailcone @ 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
