I have pulled this together based on preliminary research and smokers I've viewed. Based on what I have seen, I recognize that the distance between the end of the baffle plate and the far end of the main smoke chamber (opposite from the firebox) is a significant measurement to allow even and uniform flow of smoke and heat throughout the main chamber. Would anyone have any advice on how to calculate the optimum measurements on the gap between the baffle plate and the wall? Please note this is relatively to scale, one square unit = 4", but it is not completely exact. Thanks in advance!
