I'm building my first Reverse Flow Smoker & have a few questions for all the experts out there. The main smoking camber will be 24” X 60” rolled 3/16” steel - Fire box will be 20X20X24 made from 3/16". When it’s done I’m hopping it looks a lot like a Lang 60” smoker. I have put my specs into Feldon’s build calculator & attached a link, url=http://feldoncentral.com/bbqcalcula...1.27&fi=0,0,4,31.10,2.48&fc=10.28,14.53,82.94]Link]Link to BBQ Pit Calculator[/url] The first few of many questions are: 1. If the main cooking rack will be at the center line (or 12” from the bottom) how much lower should the reverse flow plate be? 2. How low should the top of the firebox be? Should the top of the box be at the same height as the plate or should it be below that line. 3. Lastly for a camber that is 5 feet long – would it be better to have 2 doors or just 1? I will attach pictures when i can.
