Page 2 of 11 Building The Basic Frame  The Basic Structure The frame of the forge is a basic table structure. I built mine a little wider than it is deep in order to provide a small amount of bench space. The actual dimensions of the fire box (the open area on the left) are determined the the size of the fire bricks that you use to form the firepot. Firebricks will be used to form the sides of the firepot and the open area I am calling the firebox must accommodate whatever bricks you purchase and in whatever arrangement you place them. But we are getting ahead of ourselves. At the front and rear of the firebox are strips of angle iron that run the entire width. These strips of angle iron are used to support metal slats that hold the floor of the firepot much like wooden slats in an old-fashioned bed frame.
 Close up and location of angle iron The strips of angle iron that will support the slats need to be at least a 1/2" deep. You need enough material to support the slats and still leave a little "wiggle room," as everything will expand a bit as the forge heats up.
