Fitting the F-772 FWD Bottom Skin

[RossK]

I'm just about ready to final fit the F-772 fwd bottom skin and rivet in place.
Is there any reason that I can't rivet the F-772B L&R central floor stiffeners to the angles before fitting the skin?
It would make riveting them to the angles much easier without the skin there.
I can't see any reason why not, but I've made that mistake before and have the drilled out rivets to show for it

Been a while, but If memory serves me, because a rivet goes through the skin first then both angles.

Sorry, I meant the 1/8 rivets that attach the F-772B L&R to the F783B ribs and the F601J angles, not the rivets that go through the skin and the F704 bulkhead. these guys and the forward ones.

No problem installing those 470 rivets now. Actually I wish I had done so as those lower rivets were difficult to set with the skin in place. You can squeeze them easily now.

Thanks, that's what I was hoping. They look like they would be trouble later.
