This bulkhead is crazy labor intensive for what at first glance looks like such a simple assembly. Lots of measuring, stacking, clamping, bending, back drilling, fabricating, etc.

There are a couple of pieces that go into the seat back adjustment assembly on the cross member that require you to bend along the centerline to a 4 degree angle. I don't have a bending brake, but it's just seat backs, so it doesn't have to be super precise. I built up a temporary brake with some angle and clamps that I had laying around and measured the bend with a piece of card stock that I had cut to represent approximately 4*. I vaguely remember calculating setback and K factor by hand in A&P school 30 years ago, but at this point couldn't tell you how to do it without looking it up. Found a calculator online and confirmed that the setback for a 4* bend is so small I really don't have a way to measure it without a machine shop, so I said fugget about it, and just eyeballed it. Came out fine.

At this point, I've noticed a theme with this kit. Everything critical has pilot holes or other safeguards to make it pretty easy to layout. But when you get to something that has room for variation like the seat back receiver slots, they give you enough rope to hang yourself by giving you measurements then you have to trim raw stock to size and lay out all the holes & bends by hand.

Got all the parts for the F-705 done & primed as appropriate.

Had a little bit of extra time, so I went ahead and dusted off the flange straightening tool I had previously made and did the first pass at straightening all the aft bulkhead flanges. I didn't try to get them perfect, just in the ballpark. The instructions point out that the tail cone is conical so they aren't truly 90* to the web, but suggests that you get them close at this point and tweak them for fit later.
