I am building my first smoker and I have a question about the firebox. I have an old air compressor tank I plan on using for the firebox. Every design I come across with a round fire box has one end of the tank mounted to the cooker. I do not want the door in the middle of the tank like you see on the cookers I plan on using one end as a door. My question is instead of mounting the firebox to the cooker at one end can I turn the firebox sideways and mount it that way and put an air vent at each end of the tank? Should the smoke and heat still flow ok into the cooker?
