We have thought about this previously in the context of using the EggBot as a rotary axis in a laser. (It should work but we haven’t gotten around to it– mainly for lack of actually needing to laser any round objects.)
My main concern would be that the hardware isn’t designed to resist the force exerted by a cutting tool. The bearings are light duty, and there is some slop in the tailstock bushings. So, you might need to beef it up a bit, or machine equivalent fixtures on the X-carve.
