Control Systems started

I got started on section 39, the control systems, by cutting the pushrods to the proper length:

Pushrods cut to length and rod end bearings

Aligning the control sticks on the drill press table proved to be quite hard:

Mess trying to align the control stick and its base on the drill press table
so I gave up on that and decided to use the mill :) (big thanks goes to a coworker who helped me and taught me how to use it!)

Mill with the control stick

With the mill it was actually quite easy to drill nearly-perfect matching holes on the two parts with the control stick not just "supposedly parallel" to the table, but actually clamped down to it

I drilled them #15 and later finished with #12 by hand:

I also trimmed the bushings and stick bases to fit within the control column:

and finally test-assembled the whole thing:

Some of the parts had some rust on the inside, so I gave them a good T-9 bath in preparation for primer (I'll obviously need to clean that off before applying the primer, the Prekote should help):

Next steps are priming and assembling these parts, and continuing the assembly of the pushrods.

Time lapse:

Total control system time: 6.4h
