So how does this work? Do you just use lump charcoal? Is the valve on the bottom to restrict air flow. Very interesting build. Ive got a 30 gallon drum in the shop I might try this with.
I use I mixture of lump coal and charcoal with a few pieces of wood chunks. I have 3 air inlets at the bottom. 2 are straight threaded pipe and the 1 ball valve. You do control air flow with the inlets.
