While not CNC, we had many automated relay-logic machines in operation when I first stared at where I work now. Ran these things for years. Either hydraulic fed, or gear fed. Electrical cabinets had probably 300 relays in them.

194x3 + 566x2 + 400x2 +97x2 + 6 7seg displays = over 2700 solder joints.Lesson 1: It would take an idiot that enjoys tedious repetitive jobs to complete it. Lesson 2: Get the wife / girlfriend / so to build it.
Lucky, made out of transistors and not tubes, otherwise it can used for to heat a house . JS
