Jon Anderson fired this volley in
:

Had a brochure years ago for a company that made worm wheels cut to use
standard threaded rod for the worm. Can't find it now. I might well end
up making my own, but at least want to see (if they're still around)
what an off the shelf worm wheel would cost.

Anyone run across, and remember the name of this outfit?

Jon, I don't remember the company, but I saw a neat demo either here or
on CNCzone that showed a guy making such wheels.

He pivoted the blank on a shaft on a vertical member in his mill vise,
then used a common tap of the requisite thread as a milling tool. He
simply advanced the tap sideways into the edge of the blank a few thou,
and let it cut all the way around, then advanced again, etc., until the
profile was cut full depth.

It was simple, elegant, and worked perfectly.
