I WOULD LIKE SUGGESTIONS ON CONSTRUCTING A SMOKER OUT OF A VERY LARGE STAINLESS CABINET.... SMOKER BISKIT CHIPS OR WOOD CHIPS? HOW MANY HEATING ELEMENTS? THE CABINET IS ABOUT 7' TALL BY ABOUT 3' SQUARE WITH 4 STAINLESS SHELVES.
here is a place to calculate your heating load based on size of your unit and insulation, this is total wattage, you can also break up the elements

as for controlling the elements i recommend auber inst.

a few of the items i think you would need is a PID, Relay or Relays depending on how many heating elements you get, also of you run an electric smoke generator maybe a timer to turn it off...
another thought is amazing smoker products, they have trays , and tubs that use pellets or saw dust to produce smoke.
