Completed the riveting of nutplates to the seat floors and aft baggage floor. Riveted the F-830B stiffener and F-805C seat floor support to the F-829 forward seat floor. Riveted the footwells together by back-rivetting over the back-rivet plate clamped over one corner of the workbench: came out well. Back-riveted each footwell to the F-829 forward floor panel. Cleco'd the pieces together for the obligatory photo shoot! :-)
