-Riveted the 4 nutplates onto the forward center section assembly.
-Riveted the 2 nutplates onto the Left forward bulkhead.
-Riveted the 2 forward left and right bulkheads to the forward center section per the plans. I used then bucking bar laying on the table method which yields very good results, very consistent.
-Cleco'd the aft center section bulkheads to the aft center section assembly and match drilled. Also used the reamer to match drill the 1/4" bolt holes per the plans (the plans say drill 1/4" vs ream).
-Cleco'd the left and right seat supports to the aft center section assembly and match drilled.
-Machine countersunk the forwad side hole on the aft center section assembly for the rivet that goes under the vertical bars.
-Drilled out all of the nutplates holes to #40 and machine countersunk the same.
Squeezing the nutplate rivets with the longeron yoke.
Driving the rivets using the bar against the bench. I'm pulling up on the assembly to flush the rivets
Forward section done. - note it isn't setting where it will actually go - close though.
