Talked to Todd, I believe his name is and what a nice gentleman, full of useful info. Told him what/how I planned to use the smoker and he directed me to the 12" tube and had many other suggestions. By the time I got off the phone I felt as though I had known him for years.
The tube will allow me to use it in my gas grill when BBQing and also as a cold smoker. (dhansen871, cold smoked cheese is the best. I currently use the soup can, wood chips and a cheap soldering iron from Harbor Freight.) I can also use the tube as a supplement to my charcoal smoker.
Now I have to try raw eggs on the charcoal smoker. Sure sounds good.
Thanks all!
