For the exhaust, the easiest setup involves evenly spaced holes in a circular pattern around the drum lid, as opposed to a single larger hole with a chimney tube attached. This minimizes any chimney effects, which can increase draft and create hot and cold spots and an overall hotter fire. For this exhaust pattern, drill eight equally spaced one-inch holes a few inches from the edge of the lid. An easy way to get this right is to place eight coins in a circle around the lid and then measure the distance between them. Slightly move each one until the distance between each coin is equal. Then remove each coin one-by-one and drill the holes. Depending on the type of handle and smoker thermometer you find, drill an appropriate number of holes to attach both.
