Im a newbie here and have learned a lot. While checking my old Weber 22' lid for fit on a drum the Smokey Joe lid came to mind. It fits the top of a 14" dia. x 24" tall barrel just right. I'm divorced and mostly cook tri tip and chix for one or two people. I'm going to build a smoker and add the small brisket to the menu. How about stacking one and a half of these barrels to get the grill far enough (24") away from fire? Would a fuel holder shaped like a spiral staircase hold 12 hours of fuel? Insulating a barrel this small wouldn't be a big deal. Firewood around here is mostly orchard wood with a load of chemicals in it. High efficinecy is good. Has anybody tried this? Is it a waste of time?
