I was given a compressor tank, and my old charbroiler smoker has about had it. I am a newbie and will need some advice along the way. I have to get into the pit calc and see if I can come up with some good numbers. The tank is a 50 or 60 gallon the bad is it is thin only an 1/8" thick. I will learn on this one and enjoy it for a while a build another one. The tank itself has a main body that has a circumference of 64" OD, the main part of the tank 36" long with 2 dome caps that are 5" giving it any overall length of 46". I have some 1/4" sheet of hot roll steel will that be good for the fire box? Or should I get cold roll steel? I will put together a drawing of what I would like it to be like. Question: should I build a stand or use my old charbroiler stand it will fit on there pretty well. It is the same length as the 2 grills that are on it now. I want it to be a reverse flow and build the grease trap into the RF plate. Also another newbie question, since this won't cost me much to build what are your thoughts on me using the 3 stainless burners from the charbroiler grill and have them under the RF plate to act as a prewarmer? If not recommended or not even a good idea let me know, I still want to build a killer smoker. Thanks in advance Bill Thanks Dave for checking my numbers. I used a piece of rope to measure the circumference of the tank and measured the wrong end. The circ of the tank is 64" not 51"
