Re: Looking for belt drive ISO 10 spindle

Thanks for the info.

As another option I googled and found an air spindle that seems in
this range. What are the pros and cons of an air spindle vs an
electric spindle?

One thing I noticed is that they sure use the air. What type of
compressor is able to deliver around 60cfm at 90psi? Even the big
standup shop ones only put out about 1/4 this. Is there another
style that is typically used on the air spindles?
