The list is back! Recomendations depend on whether you want to completely control all of the lathes motions, so you can cut threads at any arbitrary tpi or tpmm, or just stiffen up the drive. If the latter, there is an outfit in Wisconsin with Empire in their name that makes a pretty decent controller for about $150 for the good version, needed to run a treadmill motor up to perhaps 1.5 hp. This is not an SCR controller, so its dead silent regardless of how hard its working. This one uses the usual back emf to sense what the motor is doing, and it can do a quite stiff control. There are, on ebay, cheaper controllers, but I've bought 3 to get one that worked. Ebay seems to be a dumping ground for blown ones so read the propaganda carefully.
