OK I'm asking for opinions from the senior guys on here. I am real new to smoking but have a fabrication know how. Anyone that would like to give suggestions on the dimensions A B C D and E please feel free. These would be based on a 24" diameter tank for starters. I don't have a tank yet but can work the numbers based on actual tank dimensions. The tank I am aiming for will be a propane cylinder or air tank. Anyway the fire box will be either a perpendicularly mounted smaller propane tank or fabricated square like box. This is a jumping off point and by no means my only research going into this but these dimensions are the ones I'm most worried about at this point. Thanks all.
