Chinese Spindles

[biketrialsdave]

I know this thread is very old but just read from start to finish. Did anyone buy a Chinese spindle in the end? Any other DIY spindles come through since Henrik's one on cnczone? I can see myself designing a mill in the future and I think BT30 is the way to go.

There's a lot of these spindles on alibaba. It looks as if the main limitif factor on rpm is the bearings? How are the bearings in the Chinese 2.2kw spindle capable of faster speeds?
