|I forget, but I think it's wound with #22 enameled magnet wire.
I got the wire from an electrician-type store in Midland, MI. I walked
in and told the guy what I was up to, and he was very interested in helping
He gave me a spool of the wire to take home. I wound the coil on bare 4.25" PVC in a few hours while watching TV. My arms were dead when it was finally done. More than once I slipped and had a real mess to re-wind.
After I finished I sprayed on several coats of polyurethane. I took him the spool back and he charged me something like $4. Woo hoo!
