This is what i am building my large sausage smoker from. Not because i have that much to smoke at one time it is just i got this for free and thought it would be cool / Hot
It has a 8 in chimney now with damper. I will be able to use an outside small wood stove or electric burner inside with thermastate or propane burner. If you look closely you can see the cast iron wood chip box sitting on the propane burner.
I also have the fan that came with the freezer that i will be putting inside to circulate the air. I will be putting it on a trailer to move around as it is very heavy.
