I have decided that I want a gas fired crucible furnace for my general melting needs. I have decided I will go with David Gingery's project called, "Building a Gas Fired Crucible Furnace". I will detail my experience here for those of you that might want to try a similar project. My reasoning for this particular design was that I like the side approach to the crucible and the ease of which it looks like it is constructed. Information on this book can be found in the resource section and can be ordered through Lindsay Books.

I am excited about doing this project for another reason. My fiance has a son named Jason who thinks he is cut out to be a mad scientist. Hmmmm .... We will see. I told him he had to be my Igor first and then we will determine if he is mad scientist material. He has decided to help me build this furnace and promises to stick through with it until the end. (Good or Bad) hehehehehe :-)

Building the furnace forms.
The furnace body is constructed with forms made of sheet metal. It should be noted that with the exception of the inside collapsable form all the metal used in the body is plain black sheet metal. This is necessary because it is possible that the skin temperature can reach high enough temperatures to vaporize any galvanized coatings on the sheet metal which can lead to health issues. - Jason and I set out to making the furnace forms!
