OK, I finally got my plan and picture to come up. I decided to just start a new thread now that i have the pictures working. Here is a picture of the tank that i am planning to use for the main cook chamber and a first draft of the build plan. Has anyone built a smoker with 2 cook chambers to be used separately or together depending on how much meat you have to smoke? Would it be possible to make this design work? My intention is to use the smaller vertical smoker alone for everyday smoking. I would like to use the horizontal cook chamber or possibly both cook chambers for large cookouts. How would you figure the firebox size, exhaust size and length, etc.. ? Opinions and advice would be helpful and appreciated.
