I have an old belt driven Lathe that has NEVER even been turned on. It was a brand new Grizzly lathe (12" X 36") about 25 yrs ago, or so. Got a job of traveling and never home; so it just gathered dust.
I am itching to convert it to an all CNC machine now; because of the "state of the art" and the fact that I am now fully retired. I have the means.
Saw one on a YouTube video last night; by Centroid that looked pretty simple to do.
