Temporarily bolted the WD-813-1 bolt weldments to the gear towers and match drilled the #12 holes using the inboard hole in each corner angle as a guide. Removed the weldments and deburred the holes.
Bolted the weldments to the gear towers as per instructions and tightened the nuts to the specified torque.
Marked the holes that attach the mid cabin brace that are not to be riveted at this stage.
Cleco'd the gear towers to the forward floor and set the rivets on the forward and aft bulkheads that attach the box weldments with the pneumatic squeezer. We have ordered a long AN470 rivet set and will wait for that to arrive before setting the rivets that can't be reached with the squeezer.
