I spent a big chunk of today messing with two little adel clamps that I installed in the center tunnel just forward of the F-705 bulkhead:
What you see above is the finished result, but it took a long time to get there – mostly due to my own stupidity. At first I had the adel clamps attached to the seat ribs with screws and nuts that went through some convenient tooling holes, but then I realized that was dumb: once the floor panels were riveted in place, I wouldn't be able to get a wrench on the nuts. Duh.
So I took them back out, but somewhere during this process I managed to accidentally squash the insulation on a couple of the wires in the right-side bundle. That didn't sit too well with me, and I didn't feel like splicing in new sections of wire, so I ended up removing and replacing about twenty feet of wire. I also had to replace one of the replacement wires after I managed to cut it about three inches too short. So that was pretty frustrating.
Then I riveted in some nutplates for the adel clamps to screw into, which was relatively straightforward except for the usual difficulties that come from trying to work in tight spaces in the bottom of the airplane.
Oh, and the reason for having these two clamps in the tunnel in the first place is that they'll provide a way for wires to cross from one side of the tunnel to the other without interfering with the elevator pushrod. All will be made clear once I start wiring the strobes.
