So; this one is on test now, to see how the cycling temperatures do. I have put bottled water in it and will see if it's frozen overnight!
I painted the new control tube to make it look more like the original.
Used "tar tape" to seal around the tube. This is a cork / tar material which is used in the automotive A/C trades. Really useful.
New foam strip around the top of the cabinet. That was missing and/ or shredded along with the No-Oxide cloth.
Top going on, hopefully for the last time now!
New foam strip is nicely compressed in place. Won't leak air in around that.
And a short video!

Glad to see it put together! The influence of ambient temperatures on cabinet temperatures can complicate things a bit, as does the long period of time before temperatures and run times stabilize.

Yep, that's definitely an issue here. We had a cold snap with the weather yesterday so I may just have to defer the test until it is more normal. I don't foresee a problem, just that the previous repair attempts definitely messed up the adjustment.

Just an update! The control is working fine. It's been very cold in the building, and the cabinet temperature has been staying around 30°F with the control near the warmer end of the dial. Our weather should warm up and then we can tell better how well calibrated it is.

Our weather should warm up and then we can tell better how well calibrated it is. Out of curiosity, how cold is it there? The coldest ambient I've done measurements in is roughly in the upper 60s. I am ready for winter to end. This morning was 18F here in the Shenandoah valley region of Virginia! That may be fine for upstate NY, but I've acclimated to usually-more-moderate climate down here already.

I am ready for winter to end. This morning was 18F here in the Shenandoah valley region of Virginia! That may be fine for upstate NY, but I've acclimated to usually-more-moderate climate down here already. We had an unseasonably cold snap, where it got down below freezing for a few days. Now, it's in the 50's and 60's. Going to be in the mid 70's next week. This is really our "normal" winter. Generally 60's or so, but with "cold snaps" every couple weeks. Never any prolonged cold weather.
As far as the fridge measurements, I do have some heat in my workshop, but it is mainly task heating. The building isn't sealed or insulated to a degree where it will hold heat. My portable 10KW heater will make a nice warm work area, but I just use it when I am there and need it. It got up to the 60's in the building today (maybe warmer) and the fridge temperature was still normal.
I don't blame you for disliking that 18°F weather! That really is miserable.

Miserable is working for 5 hours doing a crane pick in 3 degree weather...

Not to go too far off topic here but it really was at first. After the first hour I got used to it and by the end of it my eyebrows and lashes were icy and I was slap happy! I have a great picture that my coworker took of me and you can see the ice on my eyes.

Excellent repair series. I have the same problem with a CK Monitor Top. I volunteered to help a local historical society fix their CK-2-B16, serial # 5283340. It has a 2-knob controller. The compressor stopped running 7 years ago. Upon discovering this forum, I downloaded the repair manual and started troubleshooting.
Results: The compressor runs when the controller is bypassed. The controller contacts are OK, but the temperature bellows apply insufficient force to trip the contact arm. The sensing tube attached to the bellows does hot have an obvious hole like yours did, but the copper tubing is heavily corroded where it passes through the roof of the refrigerator. It may have a very slow leak. 2 questions: (1) To what pressure did you charge the new tube with refrigerant? (2) Would you consider taking in outside repair work like this for a fee?
