I set about the port wing frame/skins. I deburred the rivet holes on the top skin side of the ribs, then I dimpled them. I clecoed the leading edge to the front spar also mounted the fuel tank on the spar. This allowed me to test leading edge/fuel tank join. It also allowed me to see how much I'd need to thin the top skins at the overlap joint.
Port wing with skins clecoed to the front spar only.
