Building an Atmospheric Forge & Heat Treat Oven

the long version

If you are working with metal you will eventually want to raise it to high temperatures to change its state, its shape or its degree of hardness. This piece of equipment will enable you to do it. There are several unique features of this amazing piece of shop equipment. The most outstanding feature is the high output atmospheric burner. The cleverness of arranging twin flames that impinge on each other results in a single concentrated flame that raises temperature rapidly. But radial holes that admit the extra primary air, thus eliminating the need for a blower, are the master stroke.
