If you own one of these small back yard smokers here is a cold smoker attachment I made the other day. The price is right and easy to make.
Been meaning to make this all summer but now that the weather is chilling off I got off my a** and made this up with a broken microwave from work. The recycling places are full of these things. All you need is a dryer vent hose and some short pipe connectors. A good pair of sheet metal cutters and a drill to start your pilot hole. Oh and also some duck tape, can't forget that
And you will be helping the environment by recycling
