Bit of a fiddle to get the rest together, but it went ok.

I've run it up to 3100rpm (24v) and it sounds fine. Slight noise from the bearing but I don't think that's significant.

I also measured the runout and it's less than 0.01mm.

Will post some pics in a minute.

it should have enough power to make a walnut wip out of your Y axis :)
