Going to finish mods on my smoker this weekend and hope to smoke on it Sunday. Put a 3 inch smoke stack on top in center and to air vents in the side under the chip pan will use two half in brass ball valves for air control. If this works as well is I hope it does I will insalate well and put a custom paint job on it and invest in a smoke gen of some sort thinking amazen smoke gen. If I can figer it out I will post pics asap
