We built our smoker using two metal barrels. Just make sure that one barrel is smaller than the other. Turn both barrels on their sides and cut them in half length wise. Weld hinges to one side of both barrels. Cut about a one foot square hole in the top of the larger barrel. Cut the bottom off the smaller barrel. Weld the smaller barrel over the hole in the large one. Weld legs to both barrels for support. On the inside of the large barrel weld brackets into place that will hold the grill racks. You can add a thermometer if you wish to the top of your grill side. Now light your fire in the smaller barrel and place your food in the larger barrel.
