Finished up some last cleanup/deburring tasks, then fired up the compressor and started riveting. I first riveted the shear web/aft bulkhead assembly (pic 1). It's good to do this first and slide it into place, because space is so restricted at the rear of the fuselage that getting a riveter in there would be nightmarish.
I then started on the crossties, doing the top first, working rear to forward. Left the forward crosstie box to do last. Then did the seatbelt webs (pic 2) and the rivets through the longerons into the crossties. Then flipped the whole assembly over, to rivet the bottom. Removed the bottom skin and then riveted the lower crossties. The bottom skin will not be riveted until just before certification inspection, since there is a lot of stuff that will have to be accessed in there during construction.
