There are second-hand options but rare, have you got a "watch" registered on the 'bay so it emails you if something pops up ??

Seems the spindle is always the worst / most expensive part of any build.
West London however in a rented property (I know, major pain, maybe one day we can own property). We managed to get a 32A supply installed in the garage which gives me around 7KW of power. I could possibly get a 2nd 32A installed, perhaps use that alone for the spindle - not sure.

I have had watches on ebay before, may set something up again. Ive seen before a lot more options from either the US or Germany (seems typical).

One thing getting the motor, the other is the controller. If they are a closed loop system Id expect that the motor / drive are a matched set however with 'just' a normal 3 phase motor (irrespective of RPM) I assume a more generic VFD should work. Correct logic?
