Okay that is what I was thinking. Appreciate your advice. I am going to pop it on ebay and try to sell it for whatever I can get for it and use that towards the new motors and drives. I also have some other stuff here from both builds I don't need I will try to sell. Still have a lot of scrubbing and painting to do on it. It is starting to look like a lathe again LOL Thanks Pete and Andy.
