About 6 months ago I asked my father-in-law if he could find a 55 gal drum for a UDS. A few trades later and he delivered this a few weeks ago. A vertical pipe smoker built along the UDS design. It's already turned out the best brisket I've ever cooked.
Pretty big. You can see the ball valve for airflow. Have 2 other 1' opening capped.
Charcoal basket nearly matches the diameter of the pipe.
Lower rack sitting on the chrome support rods.
Top rack supported by the lower rack handles.
It's pretty darn heavy, but will out last me.
