Router spindle idea

[HiltonSteve]

Did think about using one of 24v DC motors but thought the power supply maybe a problem. They draw about 7-10A at idle and up to 125A max when under load, i know it would not need 125A to drive a spindle but what would it cost for say a 30A PSU???

I already have the digital speed controllers to run it so it does make sense, just don't fancy running it off a couple of battery's!

This look like a spindle from an internal grinder, so the bearings should be very good.
