I would really like people to provide a review of the spindles they are using on their machines as to:
accuracy TIR
longevity
noise
speed range/control
collets available

I've been using the Hitachi M12VC on my K2 3925 machine for about 7 months now. I like the unit and have a total of three, one is a spare the other has been set up for a specific operation on a Ryobi BT3000 table saw system. I've put about 200 hours on the spindle mounted on the cnc machine. I measured TIR less much less than 0.001 when I first got it, now it has about 0.001TIR. The spare shows less than 0.001 but is not as tight as the first one. I haven't checked TIR on the third (to lazy to dismount tonight). The one I use most is generating alot of brush dust in it, very apparent when blown out with air. Noise level was very low when new but has gotten louder with time and use, still lower then any other router I have heard. The load sense speed control works well. Only 1/4 and 1/2 collets are available, I am trying to get some 1/8 and 3/8 collets made to allow greater tooling choices. The collet adapters I have tried have too much run out in them for me to use trying to keep less than 0.008 part tolerance range(+-0.004).
I really like these Hitachi spindles.

This is something I would be interested to know also.

I would like to know of these too.
Cost of spindle would be nice, too.

Anyone know how much I can get a Perske spindle for new?

i've been looking at buying a k2 kt-2514 and puting a sherline er16 spindle($380) on it for lower power consumption and lower noise. i'm planning to use the machine for 1/8 aluminum to route 19" rack faces(text and holes for pots and displays) and prototype circuit boards. someone else on this forum did it and said it's worked out very well.
