Assembled the aft fuselage side skin, longerons, and bulkheads on a leveled table. A couple of 2X4’s stand it off the table to enable access to the bottom clecos.
Bulkhead #1 was then removed, deburred, dimpled at the skin joints, the bulkhead riveted together, then clecoed back into the aft fuselage assembly.
Bulkhead #2 was removed, and will be given the same treatment tomorrow.
