Ill probably do that then when I order if thats ok. Can you send me the spreadsheet please? I really can't be bothered to work it out, Just got back from work and i'm knackered!

Anyway, I've been buying today. I haven't ordered anything structural yet because i'm still working on it but I have bought:

Power supply, 3 x 3.1NM steppers, 3 x 4.2A drivers, 3 x couplings = £264
Breakout board = £13.99
4 x ballscrews, 6 lengths of rail, 12 x bearings, er11 collet set = £350 (exc import)
1.5kw spindle and inverter = £201 (exc import)

Still need to order belts, pulleys, extrusion, ally and some milling bits. Can't wait!

Oh, I also picked up a dedicated PC today for the workshop... 2.6ghz P4, 512mb ram, 40gb HDD, old ati graphics card and 15" monitor for £30!! Not bad eh?

Jonathon, what are the dimensions of the spindle mount that you made?
