The simplest way to make a winding lathe is to get a nice geared motor. Coupled with a shaft, a shaft coupler, and stationary bearing, you can have a really nice winder. Throw in a couple of adjustable regulators, and you can have both RPM and torque adjust.
Terry Fritz has an EXCELLENT write-up on his coil winder as well as complete instructions:
Unfortunately, i can't find it here now, but i think if you search for Secondary Coil Winder on , you'll find the link.

I've been talking about permanent lathe modifications, but if your only interested in coil winding then there are a lot of simpler mods. Power drills and treadmill drives have been mentioned, another great foundation for a winding rig project is an old sewing machine, or an electric wheelchair. And with your variac and a fullbridge rectifier you could use virtually any DC motor you could find. Windscreen viper motors for instance, they're not massively powerful but should be sufficient for a medium sized winding rig. And they are 13 on the dozen.
Steve: The fact that many robot arms are buildt with DC motors, and none with AC motors should prove your point. I must admit i was shocked and amazed when i learned that these ancient motors can compete with steppers on precition equipment like these robots.

I wanted to thank you all for some excellent food for thought. I hope to introduce a workable concept and design(s) into this thread eventually as I deeply believe this is a very usable element for the Tesla Coil hobbyist. And indeed there was some excellent concepts (via pupman) on the list. Thanks!
The discussions listed thus far can save time, hassle, & expense. Winding all but the smallest coil by hand is just not feasible. But to construct a workable, cost effective jig opens vistas in the hobby that are unobtainable otherwise. Multiple coils allow a guy with limited funds and only one or two power supplies to really expand. If the resources are greater; there are limitless things to do!

The "little Winder" is a babe! Motor looks like a drill motor (?) Small projects like that give back in utility many times over; if you stick with the hobby. If you move on, a quality piece like that would certainly sell itself.......

Those are NICE. If postage weren't nearly the same price as the unit itself; I would have bought the hand crank ASAP. But the important thing is that they exist! And for that I appreciate the post. It shows they are out there. if I could find one on my side of the planet, I'd buy that baby right up!
