I had no idea that these things existed until I saw a video today on AMain Hobbies channel about the old days of the RC hobby.

I use to break in a motor before it was ran in the truck. Distilled water and submerge it and run it at half the voltage. I still have one orion lathe. But i have a real lathe now so i use that. When i became and automotive mechanic, i just missed the the time when shops would rebuild starters and alternators inhouse. Now its eithe buy new or re manufacturerd.

That was cool to watch, how much would a lathe like this be these days?
