I am looking at building a drum smoker by stacking two drums on top of each other. I like to stand it up and put the fire box inside on the bottom for now. The drums are 55 gal. Racks and a places to hang meat for smoking. There will be door on the top and bottom with one for the fire box. That what the plans are for now and they may be altered to work. FIRST TIME BUILDING ONE. I have a few questions to know what I need to do, just want to do it one time.
1. What size vent I need for air flow?
2. What size fire box I need?
3. Can the meat be put close together when smoking?
4. And anything I may need to know?
