its all a bit of compromise I think.
I just ordered a 2.2KW 8 AMPs from HK - China - cost me around 300USD, I am assuming it has steel ball bearing - ones those give up I need to move em upto something better P4 graded.
after all routers screaming at 24K rpm dont have ceramic ball bearing.
so I am assuming its worth a try.
I have ordered a Delta VFD to run the spindle.

Hmm so can someone breakout the benefits of ceramic vs. steel bearings in this case (ebay chinees vs. homeshopcnc / others). I would imagine it would have to do mostly with efficiency(heat), duty cycle, and lifetime. Because i am simply building a hobby machine that wont be running 24x7. Is it worth twice the price?
I am assuming there is no difference in noise level, most router noise comes from the brushes and commutator.
I am looking forward to seeing some comparisons between the spindles from different sources once these are all up and running. Can anyone that has one running already compare to say a porter-cable or other routers when cutting?
