Is it easier and cheaper to convert a lathe over a mill? I assume that a lathe only needs 2 motors. With the mill I will either have to figure out quill or knee feed.

I have alot more intrest in building a cnc mill but I would think that a cnc lathe would be easier. Could some1 clarify? If anyone is located in the orange county area and would like to mentor me it would be greatly appreciate it. I would prefer to convert all my machines to cnc. Am I dillusional? I've seen this on ebay but I would think that you could part it out for alot cheaper than they are asking.

My current machines aren't the greatest but here they are.
Sharp LMV w/ powerfeed
Enco Turnpro lathe
Hardinge DSM w/airfeed (probably not gonna happen on this one) no vari speed motor and no lead screws

That depends on what you want. A complete lathe is as complicated as a mill. You have 2 feedmotors but you need a regulated spindle motor if you want a constant surfacevelocity. And if you want to make threads you need an encoder to scan the spindle position.
That point is more expensive as a geared millspindle.
