Default Re: Large inductor lathe wound to a spec?

Hi Al, there have been all sorts of tubes on ebay at different times, from SRBP/ Paxolin, glass(a very good material for coils) and a whole variety of poly*** types. as well as ceramic tubes.
The difficulty could be finding the material constants of these things, probably not quite so difficult these days with Google etc.

If you are going big for the coil, have a look at cable re-reeling machines!
