Hello all, new to the smoking world here to learn! I live in Oklahoma and just got a char coaler given to me from a boss at work. I like cooking on it but would really like to build my own custom smoker. I know I can get my hands on the material and have a father in law who has the tools to help me complete it. I have some 20" bare oilfield pipe for my cooker not sure if I want a square firebox or use some smaller diameter pipe. Anyways that's where I'm at guess I should move this to the build section now.... Looking forward to everyones input!
