Is a combo hot/cold UDS possible?

    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?

    I don't see why that wouldn't work. The smoke generator you'r talking about would use 2 to 4 briquets, that's not much heat at all. You could even extend your generator using flex hose or pipe and cool it even more before it reachs your barrel.

    As with most things, form follows function. What are you planning to smoke?

    I have a charcoal UDS, which works fine for larger hunks of meat like butts and ribs, etc.

    Smoking sausages, etc. is more of a problem. You need hours of consistently low temps in the range of 120* to 180*. Like 12 hours. That is tough to do with charcoal/wood unless you are going to constantly tend it. That is tough to do for 12 hours. Most of these use a LP gas or electric burner for the heat and a variety of sources for the smoke generator.

    when my buddy gets his drum done I am gonna try the 60 watt soldering iron and coffee can method to cold smoke

    Yea you should be able to do both hot and cold smoke as long as you have two types of smoke generation. Charcoal for hot and maybe a hot plate, smoke generator, soldering iron for the cold smoke.

    I forgot about cold smoking. That makes 3 potential temp ranges for smoking.

    Cold: Smoke only at whatever temps
    Warm: Sausages, etc. at range of 120* to 180*
    Hot: Butts, ribs, etc. 225* to 250* and up

    Doing all three with charcoal/wood is tough in a standard UDS.

    I built a propane version that will do all three:

    If you could find a way to control the temps with a thermostat, this concept will work better. There are lots of burner and design options, including electric for this.

    Ok, now we're getting somewhere. To show the newb that I am to smoking (I love to cook, just a newb at smoking), I didn't realize there was a "warm" smoke. I was actually thinking of true cold smoking, and hot smoking, but warm could be possible too.

    For heat source, I would like to stay away from propane. I don't have anything against it, I just don't think it'd be ideal in my situation (and I'd have to come up with a burner and regulator). I have some electric burners and controls off of an electric range that I got for free. I can probably use the burners for electric heat inside for warm smoking, charcoal for hot-smoking. But to get the wood chips hot enough to smoke, wouldn't the burners produce too much heat for cold smoking?

    I'm not very experienced at smoking, mostly because I never had a true smoker until last summer. I built a large "pig-sized" smoker on a trailer that just isn't practical for me to keep at my house. So I don't really ever use it.

    If you are going to skip the middle temp range for sausage, the standard UDS will be fine. I've used mine for both hot and cold smoking.

    For cold? Just set a shallow pan of chips in the bottom and light one side. It will smolder across the middle and give you about 4 hours of smoke with no temp spike.

    I would also mention don't be afraid to play around with a a pan filled with sawdust to get a nice slow burning low heat fire

    BTW, forgot to mention.....if you are going to use a UDS for med or low heat smoking......stuff you would hang......the mod I made to support the grill might be something to consider. It's just two strips of 1/8" by 1 1/4" flat metal, with 1 inch tabs bent on each end. This will support the grill or hanging sticks. Bolts should be stainless, but metal doesn't have to be. Regular carbon steel works fine.
