As I'm trial fitting the wingtips, and especially when adding the rib, it looks like there is noticeable distortion when riveting the curved tip to a flat rib. I'm considering filling in that gap with epoxy/flox mix. Anyone else try this, or see potential problems?
When I move the rib aft until it firmly seats at the front, I see a varying gap along the rib. Even at the front couple of inches where the tip should meet the wing skin there is some pull down as you go aft.
When all clamped up, I see warping of the wingtip tail.
Shape of the rib vs. shape of the tip
