I'd have to re-build it to accommodate 13-thousanths wire. Its low end is
0.025", right now. At 0.020, the wire just hides in the wheel groove, and slips. I tried it with my roll of 0.020" music wire. Wheel turned, wire didn't feed.LLoyd

I wasn't doing this for spring winding. I was trying to weld with it. No soap.

How about dressing a Dremel cutoff wheel to a V shape and grinding a new groove near the edge of the roller, then spacing it out to align with the wire tube? I don't know how long a shop-made unhardened roller would last, probably enough to wind a spring but not enough for much welding.

That's true for inexpensive springs with loose tolerances. Precision springs are still wound on mandrels. Look in McMaster to see the difference in tolerance and price between standard and precision springs.
There is a book in the Workshop Practice series, "Spring Design and Manufacture" by Tubal Cain. It does have at least one chapter on winding springs. I gave it a cursory glance, some of the same problems discussed here were covered. See:

Oh, MAN! That's a good one! I got it off the freebookspot site.
THANKS!
