Hey everyone! So I just had a question pop in my head. I have a thread going under side fire box, I am building a 250g smoker. I just recently looked at a calculator for building one and probably had a concern confirmed with it. I am not connecting the smoker staight to the fire box. I am going to run a pipe into the smoking chamber, now the pipe may be too small but because it will run the length of the tank I'm thinking the airflow distributed the length of the tank may not hurt that I have a 6" pipe! The question though is how many slits do I put in the pipe and how big? I wonder depending on this if it will help the airflow where I can still stay with the 6" pipe? that's really not covered in the calculator! I'm not planning on welding the firebox to the tank until I have tested it, but was wondering if anyone has a set up like mine and can share a little advice about the pipe?!
