A marathon of edge deburring on aft bulkhead parts. Got most of them done, just the two aftmost to do.
Deburr 730 plate
Cut holes for snap bushings in all the aft bulkhead parts.
Finish deburring 706, 707,708,709 bulkheads. Now that's done!
Cut 728B and 729B angles
Fab 729C angle. The plans call for this to be modified for a 88.5 degree interior angle. I cut a couple of vise jaw protectors, clamped it down and put a scrap of wood on top. One good whack with the 20 oz framing hammer and viola! As close to 88.5 as I think I can get.
Drill 729A bellcrank rib to 729B angle. Didn't like the way this turned out. I haven't figured out what the drawing is trying to show with the first hole in 729B. Using that the way it seems to be drawn resulted in the aftmost A-B rivet hole being too close the edge of the angle. I clecoed the 730 reinforcement plate to the bellcrank rib, clamped the 729C in place, then clamped the B angle in place with the A holes centered lengthwise, and then drilled. I think it worked out just right the second time.
Finished cutting and cleaning up the control column mount brackets.
