Mounted the F-811 bulkhead and the lower longerons into position.
Clecoed the left and right F-857C seatbelt angles, the F-8008, F-809, and F-810 bulkheads.
Riveted the aft end of the baggagebulkheads to the F-808 bulkhead.
Clecoed the bottom skin in place. It took a little longer than I expecetd, but with one peron, and no assitance from ropes, straps, and so on, it turned out just fine.
