Riveted some on the left wing with my Dad. Got about 25% of it done. Did all these rivets using the back rivet method, which I'm not so sure about. With the pressure up, it banged up the skins from the slight movement of the bucking bar. With the pressure down, it banged up the skins still. I'm going to try conventional riveting next time I find some help. Then I dimpled the right wing top skins, got the inboard one and the wing walk doubler done and cleco'd in position ready to rivet. Got the exterior holes dimpled in the larger outboard top skin.
