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 all of the foundry construction items & only need to acquire the electric components. I want to see what we have lying around the space before I purchase anything.
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.

Chris brought in the coils last weekend so we have everything needed for the hardware. First we need to cut the fire brick, which requires me to bring in all my heavy power tools. Player2 has a box truck that he indicated we can use so it's just a matter of coordinating it with him. Hopefully we'll get them in this week and the cutting can begin.
We still need to get the electronics but those items do not need to be decided before we pour and make the furnace body.
