I recently found an old dead fridge that had a steel exterior shell and an aluminum interior shell. It was in bad shape as it had no top. Must have been an under counter built in. I disassembled it cleaned and painted an tossed the old insulation in the garbage. Then cut holes for the drafts. Bridged the area between the shells and reinsulated with FG insulation. Installed an electric burner and built a new external smoke generator. I have an AMPS on order. The new smoke generator is a tiny weber style pot with 1" pipe fittings plumbed to my new smoker. My old smoke generator was a converted tiny charcoal or wood stove about the size of a round 1 gal can. previous ones actually were 1 gal cans. I pump the smoke into the smoker using an aquarium air pump thru a venturi. Works well.
