I bought tonight a SS Commercial Refrigerator. The guy still said that it still worked. Craigslist $150! It measures outside 80" tall, 25" wide and 33" deep. I going to convert this into a electric smoker with some type of temp control. It does have plastic insides for I am going to do sheet metal. what gauge metal shout I do and what kind of metal? What size of heating element and where to get both element and temp control thats a good one? Hope you guys follow my build. its my first smoker build so wish me luck!
