Is it worth the trouble? Coiled nichrome is pretty cheap at www.infraredheaters.com. ($30 for enough to make 3 2 x 2 foot vacuum former ovens, IIRC.)Quote:

I used a 3/8-16 threaded rod, approximately 3 ft long to coil some Kanthal wire.
Cut a notch on one end of the rod to hold the wire.
Wrap a couple turns of wire by hand to get it started.
Chuck the other end of the rod in a cordless drill/driver.
Keep the wire taut, use low rpm and the wire will coil around the thread form.
It's not easy, but it gives good results.
