I have been lurking on this site and others for a while trying to capture as many details as I could prior to building a smoker. Hopefully a little research has saved me from a few rookie mistakes. I could have bought a Home Depot version for less than the cost of the raw materials I used. but that is no fun. I started with a 100 lb. propane cylinder, followed the formula for firebox size, etc. and finally have a finished product less paint. I will post pics after it is painted.
