Looking for advice on budget machine for watchmaking

[FatFreddie]

I'm currently designing and working out moulds etc to build small Fixed gantry Epoxy Granite based machine. It will have profiled linear rails and use Closed loop stepper system using preloaded double-nut ball-screws.
The Epoxy granite structure will minimise vibrations and resonance and coupled with linear rails will make for very high quality surface finish. The preloaded double nut will make for near zero backlash and coupled with Closed loop steppers will make it very accurate. Will most likely have 2.2Kw spindle on it which will just about match the machine accuracy.

I'd be very interested to hear how you get on with this - I'm thinking of doing something similar.
