I have been giving some thought to making my own smoker. I currently have a chargriller w/ SFB. I have owned it long enough to see where mass production comes before quality. So, I want to build my own smoker. I know how to weld and I have access to a lot of metal fabrication tools. My problem is that I don't know what design would be the best. That's where your thoughts and ideas come into play. If you were to build a smoker, or have one built for you, what would it be like? Namely, would it have a side fire box, or be vertical? What kind of materials would it be made out of? I have thought about making it with a double wall and insulation technique. My only real requirements are that it will be portable, i.e. can wheel it around the patio, put it in the back of a pick up truck. Also, it most likely should be charcoal powered. So, feel free to post your ideas, suggestions, pictures, sources for plans, or whatever. Maybe between us all, we can turn out one bad mutha smoker.
