We primed all the mid-fuselage bulkhead (and some of the mid-fuselage rib) parts:
Washing parts for primer with Prekote
Priming parts
Primed mid-fuselage (bulkhead and ribs) parts
More primed mid-fuselage (bulkhead and ribs) parts
Even more primed mid-fuselage parts
and then started riveting them:
Riveted mid-seat rail supports
Center section bulkhead with the doubler installed
Rear side of the center section bulkhead doubler
Mid-seat rail supports in position
Most center section parts are also bolted on, so I torqued those properly:
Torquing mid-seat rail supports to the center section
I did the same for the aft center bulkhead:
Aft center-section bulkheads with doublers installed
After clecoing those parts to the bulkhead, I torqued all the bolts:
Aft center-section bulkheads assembled with bolts torqued
and riveted the plastic wear strip:

I riveted the rear spar side channels:
Rear spar bulkhead side channels with gussets and nutplates installed
and started riveting the rear spar attach bar, only to realize halfway into it that the shop heads were supposed to go on the other side :(
Rear spar attach bar, with rivets on the wrong side :(
After replacing those rivets, I finished riveting the spar attach bars and the idler arm brackets:

Finally, I riveted the fuselage bulkhead (rearmost bulkhead, just before the baggage compartment), which has surprisingly little done to it at this stage:
