I clamped the wing walk doubler to the left inboard skin and then drilled the holes for the ribs using the prepunched skin as a guide. Got to love these prepunched kits! Once this was done, I clecoed the top inboard skin and doubler plate to the left wing. All 4 of the left main skins are now clecoed in place and ready to be drilled.
