Last March I started putting the bottom wing skins on the wing. It is quite a bit easier to facilitate riveting the skins with a partner. For a variety of reasons, Brad's schedule and mine didn't align well until today. Brad assisted me with the bucking bar and we finished riveting the bottom wing skin on the left wing.
Brad's arm was getting pretty torn up, so we cut the toes out of a sock to make a sleeve for his arm to minimize the scraping and cuts from the ribs and skin.
