In pursuit of perfect smoke I tried a lot of different combinations and I think I've finally got it.
Using my H burner for heat and my A-Maze-N Products 12" smoke tube mounted outside the firebox I can get a solid 4 hours of perfect Thin Blue Smoke.
A little foil over the end of the intake on the tube slows the airflow to the pellets and keeps them smoldering nice and slow.
I pushed a piece of 3" dryer vent into a soup can, perfect snug fit, then used a hole saw to drill a hole thru the bottom of the soup can for a 1" close nipple with lock nuts on each side.
