Leveled up the frame front to back. Alicia then helped me fit the skin onto the riveted stab frame. Releveled and cleco'd. Thought I was gonna get lucky because all of the hole accepted cleco's pretty well, however when I attempted to drop in the A4 rivets, they offered resisistance, so I guess I'll have to still final-hole-size drill them out. Drilled all holes on bottom of stab to final hole size. Next: Next will have to take skin back off and debur.
