From a quick scan back through the thread it seems a 1.8kw 3000rpm AC servo at 1:1 drive should be ok if i keep back-gear.
Its about £350 so not too bad.
Larger ones may be better but then top speed seems to drop to 2500rpm or 2000rpm so would need a ratio increase.
I have a feeling based on usage that it really does not need max spindle power at all.
