Original poster: "by way of Terry Fritz <twftesla-at-qwest-dot-net>" <Teslamagnifier-at-aol-dot-com> I'm using two part epoxy & painting it on while the coil jig is rotating. Two coats. lightly sand and then a coat of varnish to be pretty. I don't have patience to wait for all those varnish coats to dry. Lossy?? maybe you lose an inch of spark length Bill Shepard
