I was about to recommend the exact same thing. Epoxy granite is used by some world class machine tool builders.

I think an interesting modern take on the Gingery machine, would be a homebuilt machine tool; built from epoxy-concrete. Linear rails, servos, fly-by-wire controls with force feedback.

Machine form factor would be a la Mazak Integrex but much smaller and fits in a two car garage. Total envelope would be 8"x8"x8"; high spindle speeds w/ low depth of cuts. That should compensate for the total lack of stiffness :)

There are several people who have documented builds of epoxy granite mills. Much bigger than what you described generally, but still garage machines. https://www.youtube.com/channel/UCIuvJtM342E7p2nEpwTGbDw and https://www.youtube.com/channel/UCssIc2lLpX1nIHkymAzEptw are two of my favourites.

I'd really like epoxy granite linear rails for the noise dampening attributes. If they're flexy they could just be bolted to a metal or wooden support.

What do you mean by fly-by-wire controls? Just manual jogging with CNC controls or do you mean something more specific?

[leon_sbt]

Exactly like jogging with CNC controls; but with force feedback. I have done some cuts with the Haas in handjog mode. I always feel iffy doing it, since I can't feel the feedback from the cutting forces.

That sounds awesome. Do you know of any builds that have done that?

Pointers would be much appreciated.
