Hi Swarfing, you posted the same time as me so missed your reply. yeah think the DC will be fine for this little mill but I was just trying to work out which would be best. Didnt what to spend time making mounts etc if the ac motor on vfd would be as good, it seems that the DC wins on low rpm to torqure ratio which is mainly what I need for this machine.

The sad thing is i need to get the ac motor working to make the bits to convert to dc, that is providing the spndle is ok.

Sounds like your most of the way there then. Just need an appropriate controller and your away :-)
I was hoping to cannibalise the motor controller from the tread mill and control it with a Adruino.
