After fitting and drilling RH top and bottom aft skins I turned the wing over and aligned the pre punch holes of the top forward skin over the top aft skin and clecoed them together with the pilot drilled holes in the main spar. I pilot drilled top fwd skin to fwd ribs after verifying alignment of the pre punched holes with the blue sharpie line marked along the center of each rib flange and then I turned the wing over and prepared for the fitting of the fwd bottom skin.
Clecoed Top Fwd Skin to Aft Top Skin and Main Spar.
