Howdy, Don't know much about smokehouses, but interested in putting one together that could possibly be a prototype for the occasional spare time money maker type project. I have had some people ask me for oak lumber for one since I have a sawmill.....is this a popular building material for a smokehouse? I am familiar with the metal ones and have sheet metal fab experience, but around here that niche is pretty well occupied. I do like the the idea of a more rustic and less industrial look for a smoker, but would like some experienced guidance on what works well. Thanks in advance.
