So before I put aside my "Projects In Metal" mags. I thought I would post one more project. This one is for a very quick and easy aluminum melter. You have been interested in melting aluminum but are not crazy about playing with charcoal, coal, oil, or even propane or natural gas. You are limited to a small garage or basement shop space and open flame and products of combustion are not a good idea. The answer of course is an electric furnace. I built Gingery's electric furnace 35 years ago and it worked out great in my basement shop at the time.
This plan from the June 1991 "Projects In Metal" is far quicker and easier than Dave's plan, no playing around with refractory mixes or building housings from scratch, and the size compares with Dave's, to build his shop from scrap machines. Materials are relatively easy to acquire, your local kitchen stove parts supply store will handle the electrical and most pottery supply stores carry a brand of hi-temp insulating wool.
