I stopped by a local Government auction and bought this large aluminum proofing oven. It runs on 120v, has electric heat to about 180 degrees and a separate heat coil for humidity. The electrical section is built to be removable so the box can be steam cleaned. I really have no clue about larger smokers so any input would be appreciated. I plan to add an outside skin of aluminum flashing and insulation as well as remove the window and replace it with an insulated panel. I have an old fisher mama bear I could use for the burner. Is that going to be too large? Should I leave the electrical parts in the box and use it as back up heat (or humidity) in case the smoke can't maintain the box temperature? I was thinking about putting the smoke intake and output in the bottom half of the box, then a stack far enough above the box to create a draft. That way, I can block off the top half of the box to smoke a smaller load. Any guesses on if that will work? Any other ideas?
