@thecrazygreek:Thanks. It's nothing to be proud of, but it works. The top rim has holes to span rods for hanging objects. I will eventually get around to building a fully insulated (and regulated) one that may fit a motorcycle frame. The elements are very similar for most resistance heating, a Kenthal coil in a bed of ceramic, jacketed by a nickle plated tube of copper. You should bend these gently when they are brand new...once they have been lit up they could break or short internally. A guaranteed fail if you re-bend them. Loud pop! These coils get really hot at the surface (1,500F+) because the actual heating of the air is not very efficient. When the burner on an electric range is red and has water brought to a boil, the temperature of the element is above 800F. If you contain these temps in some refractory material you can melt metals in a crucible. The box on the side where my cord comes in is stuffed with fiberglass to keep it cooler. If you make something like this for yourself, include a ground lead like I did just for safety.
