How Would You Upgrade An Old Ox CNC Build Into A Serious Machine?

... and honestly 0.8kw spindle is enough for it. Anyways the spindle is a good buy, could be moved on a new machine

I think one of the common design considerations for a 2.2kW water-cooled spindle is not so much the mechanical power, but more the ER20 collet size (20mm tool shank dia) afforded by the larger body. 0.8kW tend to top out at ER11 - which covers a 1/4" shank but not much more.

Yeah... when I wanted other sized collets for my Dewalt router I had to order them from the states and got hammered with import duties... just because I wanted 3mm, 4mm, 6mm and 8mm collets to give me some flexibility... and then I ordered the wrong 6mm collet so had to reorder as just returning the wrong one to the states costed more than actually buying another one.

At least I will be able to buy ER20 collet sets in the UK.
