Spindle motors resonable options

[wiatroda]

the draw bar hole in the centre could this be used to retain the bearings and a pulley ?

Best regards Keith

Keith, did you mean something like this ???

BTW, my grub screwed shaft collar is still keeping strong. Nothing got loose so far. While I'm writing this the machine is cutting out some profiles from 3mm mild steel :). Recently I had an idea to make CVT to transfer power from motor to spindle. Few problems are bugging me: high cost of materials to make a 150mm dia pulleys and availability of multi-speed belt( like this http://www.gates.com/index.cfm?location_id=3106).
