At what height do you place a grill from the bottom of a 55 Gallon Drum with a flat lid for a good smoking? I will smoke chicken, turkey, and most of the time pork.
You can see the pictures in this thread.
I put a set of bolts through at 3" from the top and another set 9" from the top so that I can run 2 cooking racks at one time or I can use the bottom set of bolts (9") for large items like turkeys. Hope this helps.
