I drilled the F-728A vertical channel to the F-706 bulkhead, then removed the channel. I fit, drilled and riveted the F-728B angle to the channel, then re-installed the channel permanently in the fuselage. I needed to use a narrow bucking bar to set the rivets attaching it to the top of the bulkhead. I fabricated the F-635 Bellcrank by riveting the components around the VA-146 flange bearing. I made the tubular F-635C spacers and fit the bellcrank in the fuselage. I square the ends of the spacers and fit them precisely between the area washers on each side of the bellcrank and the support ribs on either side. The bellcrank was centered between the ribs and rotated smoothly, with no side-to-side play.
I then removed the bellcrank, washers and spacers and stored them.
Time: 4 hours.
