I don't have any full pictures of the smoker- I'll try to get one. Spent about three months building it. The smoke chamber is a 250 gallon double-wall stainless milk bulk tank- smoke goes through 4"double wall pipe to the lower chamber of the smoker where it is diffused through a steel heat shield and aluminum diffuser. When I just run coals in the tank, the smoker will get to about 130. I have an electric element to supplement heat and can max out the temperature in there around 225 degrees. Very even heat this way. Sorry if the pics are too big- I'm not sure how to resize!
Here's a better view of the front of the smoker from the bottom of the stairs. I think there was 100lbs of jalepeno pepperjack summer and 100lbs of slims in there. (will hold 400lbs of summer fully loaded)
