Has anyone out there built a welding rod dryer? An old fridge or freezer with a light bulb is one idea thrown out earlier. I'm looking for something more like the ones in the catalogs which look like a bench top furnace. Something small and quick. A ten pound capacity would be ideal. Right now the idea is a two pieces of pipe/tubing with a layer of insulation between them and a heating element. One end would be capped and the other would contain a vent.
