Overview

I am going to be building an Electric Shop Furnace so I can start casting my own metals for various projects from scrap metals readily found on trash day.

Current Status

I have purchased many of the items. I am looking for a local source for the fire brick. If you have parts lying around that are on the list, we'd appreciate it.

There are several designs for these, both using gas & electricity. I opted for electric since it is quieter and safer. I don't play on melting steel or other metals that have a higher melting point. I have the plans that are described at Dan's Workshop. This design should allow us to work with softer metals like aluminum, copper & brass.
