I met a guy once, well, sold him a motor, who had a mill/lathe, before I started in metal work - but had an interest to start. He had a busy bee, an older model. Not a small machine, but not huge. I asked him about it. He said it served its purpose, but lacked rigidity. One of those scenarios where it does many things but not many things great. Many limitations.
He was in the process of restoring an old series 1 BP. Which was why he wanted the motor I had.
