Found some matches.
I've got a cooker made from an old fuel tank that has worked quite well for me with direct heat charcoal. It has an adjustable vent (like those on a Weber grill) on each end. I'm adding a smoker box to one end of the tank. Should I also add a chimney to the opposite end for better air flow? Or will the vent suffice? If a chimney is a good idea, is there an optimal diameter and length? I'm just getting into smoking, so this may not be my first dumb question. Thanks!
