Original poster: "by way of Terry Fritz <twftesla-at-uswest-dot-net>" <RQBauzon-at-aol-dot-com> is it possible to make a coil without the secondary? I've seen huge coils, like the ones that make 50' arcs, and i haven't noticed secondary coils. Besides, if I was buiilding a big coil, I wouldn't take the time to wind a 15 foot coil
