I'm looking to build a UDS, or some other type of smoker. I can do just about anything I want given the time. But I don't know what I want or what would work best, and the less time required the better because I don't have a whole lot of time to work on this so I think a UDS would be best. Materials aren't a problem, I can get just about any metal I want for free or cheap. My question is, can a combo cold/hot smoker be made out of a drum? I live in a subdivision and I don't have room for more than 1 smoker, so I need to keep it to one, but I can't pick between hot or cold because they both serve different purposes. So my thoughts are, make a regular UDS smoker as seen here on the builds, with the charcoal basket in the bottom. Then, on the side attach a smoke generator like I've also see here. I'm thinking about a generator that has the tall tube, with a grate in the bottom, and a tube that connects it to the smoker. I know I've seen pictures but I can't find any now. Does this generate cool enough smoke for cold smoking?
