Build a firebox on the outside with cement building blocks against the box on one side and vent the back into the wooden structure. If you have an overhang on the roof, drill some 2 inch holes under the overhang for exhaust. Make sure the firebox is long enough that the fire is not too close to the wooden wall to catch it on fire. Smoke away and enjoy your own smoked bacon!
