Hi Ross
i use ex washing machine motors on both my machines. 6 inch chuck lathe and Gingery clone horizontal mill. They have well enough torque and are variable speed. I make the controllers at calenterprises.

Best Regards Keith

Any chance of digital or analogue speed control?

Hi magicniiner
Yes I have make a model which can use PWM to control the speed. I test it with Zeus but Mach 3/4 is supposed to give out similar pulses. You have to modify the tacho generator on the WM motor because the desgn is made for some of the older motors. I have that instruction in my on line leaflet. On a lathe its best to use the WM pulley for reduction. I had a chap use it on a pillar drill he complained the controller was getting hot but then it transpired he was trying it without reduction gear so the whole thing was under stress. I am an engineer electronics mechanical anything which is needed..

Cheers Keith
