The directions get more vague with every step eh?
I'm just a few steps ahead of you. I'm about to rivet the side skins into
place. I don't have any "pucker", but I think I know what you're referring
to. Where the bend in the side skin begins, there's essentially about a
partial #30 size hole drilled at the corner likely to discourage cracking.
I think there's an inevitable amount of daylight that will be visible
through that "hole" at the intersection of the bottom skin, side skin and
623 rib.
In my case, I feel confident that it's all fitting like it appears it
should, and I do expect some daylight at this point. I expect it will look a
little better after riveting, so I'm reserving final judgement. I might
plunk a dab of proseal or rtv in that area from the inside.
Here's a pic of my fuse from when I was originally doing the bend. Note that
I smoothed out the two small sharp points in the side skin at that
intersection. I'll take another pic of that intersection after I rivet it.
(Might be a few weeks out due to imminent biz trip...)

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 @ 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

Don,
Pretty sure the bent side skin flap is supposed to lay beneath the belly
skin, not sit on top of it. See this photo:
