Began installing the lower wing skins to the wing. Rather than clecoe the skins from aft to the J stiffeners, I only clecoed half the way. This allowed more flexibility in moving the skins so I could reach the rivets nearest the rear spar for bucking. After reviting half the aft rib fwd, I then clecoed the remainder of the way to the J stiffeners to finish that first part of the riveting. Definitely the most difficult part of the riveting process yet. Shawn Cogan helped me tonight.
