May 21, 2023 2.0 Assembling pushrod bellcrank brackets Category: Controls
I decided to start working on a new section and begin working on the pushrods that control the aileron actuation. I started by measuring, final-drilling, and deburring. The right aileron bracket needed a nutplate to be riveted on with the squeezer, which will be used for the autopilot servo. Both brackets needed to have brass bearings installed into them for their pivot points. I probably should have made a greater effort to sand down the outer diameter of these bushings a little more than I did, since they were still quite difficult to push into the brackets and probably will be challenging to ever replace.

Unfortunately, it looks like one of the AN4-32A bolts that Vans shipped for the pivot points of these brackets has a bend in it. The bend was enough to make it impossible to easily insert into the bushing, so I'll have to order a replacement for one.

I'll also need to research why the mounting brackets already attached to the wing spar might be bent too close to allow this aileron bracket to easily pivot. I suspect I just need to slightly bend the angles apart slightly, but I want to verify.

The next 4 brackets needed to have pushrod-end caps inserted and then match-drilled using existing holes in the brackets. After a little more deburring, I pulled some blind-rivets to hold the ends in place.
