Have got a double door refrigerator that was made in 1952. Everything is metal, it weighs 300lbs or so. I am going to build into a charcoal/wood smoker. any ideas from anyone. I have built 2 old 1 door refrigerators into smoker but this one could be a big undertaking. I was thinking of drilling holes in the bottom so the heat and smoke will come up through the holes. Please let me know if you have any suggestions.
