I am going to make a guess for this, when you use tooling on a
rotating cylinder of raw stock, a spiral of metal comes off, in the
shape of a coil. If you do this with a propertly set up lathe, you
should have a scrap piece which is the desired coil. Now if you can
do this work with a lathe, and cut out exactly the coil you would
like, turning the ID and OD, and the thickness, you should have the
conductor you need already in the turned diameter of the coil. Then
it would be wound onto a former, screwed into it, so to speak. Does
this agree with reality? I don't know.
