I am making a somewhat unique upright smoker. I want this to burn wood like an offset smoker does and not "smolder charcoal" like a uds or weber smokey mountain does. It is my understanding I will need an exhaust of some sort rather than just an air adjustment on the top.
specs - 60 gallon compressor (20" diameter x 48" length). 17 x 17 x 19 firebox.
Can you help me with the length of stacks? Currently I have 4.25" inside diameter pipe but am more than willing to buy a new size if need be. I want it to be right! I have a general idea based on feldons calc but am I wrong in thinking that because it is vertical, it already has somewhat of a natural draft due to heat rising...thus needing less of an exhaust? Please help?!?
