Clecoed the root skin in position. Then used the cargo straps again to pull the leading edges down, then clecoed. Curved the mating piece between the 2nd rib and the root skins...drilled and deburred.
Played around quite a bit with the leqding edge root skin to get it right...never 100% happy with these skins, but it's a tough one to get right. Added extra rivets to take some of the curve out of the leading edge root skin.
