If strapped for cash you can buy a straight shank ER collet chuck and a couple of bearings on ebay for very little, then add whatever motor you can turn up. If you want to cut aluminium or steel, rather than vapourise it, 2-3000 rpm is good.

Hi Robin,

If strapped for cash you can buy a straight shank ER collet chuck and a couple of bearings on ebay for very little, then add whatever motor you can turn up. If you want to cut aluminium or steel, rather than vapourise it, 2-3000 rpm is good.

I had been thinking along those lines as a serious option for the future, there is a thread I have seen where a gentleman is doing just that (Ah found the thread again: http://www.mycncuk.com/forums/diy-pr...le-design.html). Prior to seeing that I was struggling to work out how to do the collet and spindle. I was totally unaware of the ER spindles! I probably have a suitable motor somewhere in my Dad's shed.

Thank you very much for the suggestion.

Cheers,

Geoff.
