Hi Ed
Some pictures of the one I made for my VM-E, I got information on what to buy from John Baguley's website and used the speed controller as described on Myforboy's youtube video. I'm afraid it was cobbled up from materials I had, the pulleys, belt and speed controller are from ebay and the motor, power supply and drive unit from Stepperonline. Been in fairly hard use for over a year now with no problems, in fact this morning was the first time I've looked inside it since building it. I enjoyed making the dog clutch, not sure if it is entirely necessary but it works well. The main structure is all alloy to save weight, and because I had some! Bit of a fiddle to connect the remote potentiometer and switches to the control card, but despite hamfistedness it is doable. there is no facility for rapid traverse other than winding the speed control pot up fully, but if you were into things like Arduino's it should be possible. There are other pictures in my album one has the pasrt numbers of the motor and controller. Hope this is of use. Dave
Meant to say the arrangement uses the original feedscrew end bearing arrangement, which in this case had been faced off square so it was all very easy to arrange. I didn't bother about extending the shaft to fit the feed dial as the machine has DRO fitted.
