Sean was over to help finish off the riveting of the fuselage skins. We started by installing the fuse to the new rotating stand then easily inverted it. We got to work setting the rivets along the aft side of the wing spar box to the bottom of the fuselage. Then we continued on working aft. The skin seems all came out nice and tight. Then we got up inside to set some AD4 rivets joining the aft armrests to the F-807 bulkhead and various gussets and floor angles. It was a long but very productive day and I couldn't have done it without Sean’s help and skill!
