I've got the tank and have mocked up a drawing to show how I think the build will go. My main concern is my Firebox. The tank is relatively thin metal. I know it will be hard to hold heat in the chamber. Should I beef up the reverse flow plate by using 1/8” metal or more. Or should I make the fire box larger than 1/3 the chamber size to keep the heat going? According to pit calculators I need a 24” tall x 32” wide x 32” deep firebox. Which will be a little more than 1/3 the size of my tank. I thought I would put 8 total intake holes on the firebox, 4 on each side. I've included the drawing in an attachment and have saved it as a .pdf and .doc. Please check it out, I welcome any comments.
