i've been having thoughts on trying to build a homemade smoker. now if I was to use a large say propane tank, in theory I could take the controls off a barbeque, get a regulator and some burners. now I've never attempted anything like this before, but I'm a pretty handy guy and I'm confident I could fabricate it, however I dont have much experience with propane and the accessories. will propane make enough heat for a large smoker if I had the burners in an offset box, or on one end of the smoker and made the chimney on the opposite end? is it not practicle due to expense of propane and would use too much for a large scale smoker? anyone out there attempt this yet and have any input? thanks
