Re: Looking for belt drive ISO 10 spindle

Yaa, I'm not use to looking at the industrial air compressors but
once I found them (just now online) I see that it would take about a
15HP compressor. Pretty poor payoff- 15hp for 1hp at the spindle!

They might have other advantages that outweigh this though? Quiet?
Long life? Don't bog down as easy? Lighter (for quicker
acceleration)?
