OK justinat what is the base machine (MFG, Model and such) because it look alot like an older SIEG C3. I was just wondering what changes might have to be done to convert one of the standard mini lathes such as this.

Maybe some small changes will make it useful.

Its a Clarke 12in bed. Basically the same as your pic there are a bunch of companies that brand these lathes. Mine was purchased a few years ago from tractor supply.

I started off with a 1605 ball screw and mounts ( got them from automation technology but they are available from a bunch of sources ) for the carriage

The cross slide was a little more challenging as a small ballscrew setup is pricey so I decided to go with acme lead screw single start 3/8 righthand( From McMaster ) and a Delran zero backlash Nut ( From Dumpster CNC ) - At this stage I'm still working out the bearing setup for the Leadscrew

The electronics I went with a Gecko G540 and 381 oz stepper motors a index pulse board and Variable speed control ( From cnc4pc.com )

my goal is to have a machine that's capable of making small parts and treading.

the one down side I see with these machines is they were never intended to be more than a hobbyists machine and stock they have a very rough build quality. I had this one sitting around so I thought it would be a good learning experience.
