I read some where on the 'zone about someone using a servo motor for a spindle of there mill.

Is that doable?
Is it worth doing?
How big of a servo would I have to have for my X3 to get about 3k-4k rpm out of my spindle.

I would assume it would driven by a Gecko & mach 3, not sure on how any of this would hook up.

What are the pro's and con's of using suck if it is even possible?
