-Riveted the reinforcement bars onto the rear spar carry through bulkhead. Also riveted the seat belt attach lugs and the corner gussets per the plans.
-Riveted the nutplates onto the inboard seat rib angles.
-assembled and rivetd the seat belt anchors together. Here is where I screw'd up and riveted the right one upside down. Had to drill out the rivets and re-do-oh well!
Good progress all-in-all!
Riveting one of the corner gussets to the rear spar carry through.
