Hey y'all, I have an OKJ Highland like the title says, and I have seen in some other forums that folks are extending their smoke stacks because it increases the air flow and draw through the smoker, thus making it easier to maintain a steady temp. I am curious if anyone on here has done it and how much you extended your stack to find the sweet spot. I am looking to be able to maintain a 225-275 range, depending on what I am smoking as efficiently as possible. Will this reduce wood consumption? I put a new split on every 30-40 minutes. As a side note, does anyone have a link to a smoker specification calculator? That way, if I do decide to extend my stack, I know how many inches to extend it. Thanks in advance for your time.
