Rudder pedal and Beringer attachment

I drilled the rudder cable guides:

then removed rust from the pedals, rust-converted the interior of the tubes, and assembled them:

The holes in Beringer's provided bracket for the ALIR regulator, as expected, did not match the delrin bearing block from ControlApproach, so I duplicated it in .080 aluminum to drill new holes:

Per Beringer's manual, I bent the bracket's tip so it hangs lower than the pedal tubes:

I duplicated the regulator holes from the original bracket and checked that they still matched the regulator:

then match-drilled the ControlApproach block into the other end. One deviation from Berginer's suggestion here is that I'm mounting it outboard, since the ControlApproach pedal arms go inboard:

I also match-drilled the Beringer parking brake bracket to the (standard) left pedal bearing block, and switched the -22A bolts on these and the center blocks to -23A to account for the added thickness (even though Beringer's manual for some reason still calls for 22?):

And then...I saw this post and the install instructions for the Aircraft Specialty hose kit, and changed my mind :) having the regulator on the right side would require the hose to go from side to side twice, so I decided to instead do a cleaner variation of what they did - to attach the bracket along with the regular bearing block mounting plate, I decided to make a combined part:

This is about the same weight as the original 2 parts (in spite of being .125 vs .080 for the original bracket, since it's also removing duplicate material), and is much simpler and less hacky. I didn't bend the arms this time - as long as I keep the pedal in the aft hole of the delrin block, there's no interference - and if I ever need to move it to the forward hole, then I can bend the arms.

I test-installed the pedals with all this, mostly to measure and try out the hoses:

I still need to remove the left mount plate and prime it, and I can start looking at hoses - from Beringer's video they seem simple to make, but I have no way to pressure-test them, so I'll likely just order them from Aircraft Specialty or TS.
