Seat back supports / Elevator bellcrank

This morning's project was the seat back supports on F-705. I started with a pile of random aluminum:

And, some time later, the seat back supports are built and fitted to the bulkhead. These allow you to adjust the angle of each seat independently.

It's fun making parts from raw stock that's not sized or punched for you, but I wouldn't want to build a whole airplane that way. In the olden days you had to practically mine and smelt your own bauxite – not for me, I wanna fly.

I also spent a quick couple of minutes fabricating the elevator bellcrank. Since I know I'll be installing an autopilot pitch servo, I went ahead and drilled the extra hole in the bellcrank for the servo linkage.

Mary is taking a nap now so I knocked it off with the air tools and the noisemaking and the etc.
