A short time ago a friend of mine who recently had purchased a Bubba Smoker and started a weekend BBQ and Catering business, suggested that I modify my little Char-Griller into a reverse flow smoker. During my research I discovered this web site and learned tons watching several builds. So after having gone ahead and changing my little grill into a reverse flow, and being very happy with the results, it was now time to get serious. I found a 250 gallon propane tank and got busy. I also acquired a 4’ by 8’ sheet of half inch thick steel. I haven’t seen anyone use half inch yet but have seen comments saying the thicker the better. I welcome any feedback anyone cares to offer as I proceed. This will be fairly slow progress as the weekends are the only time I have available to work on it. I started two weeks ago, here’s what I’ve done so far.
