A few questions if i do build one.
1) Where would be good places to hunt for a barrel?
2) Has anyone considered putting a door outside of the charcoal basket just in case the charcoal needs to be attended to i.e add more charcoal or wood chunks?
3) I notice many people either put air inlets that go up the side towards the top and others just put a ball valve at the bottom, What's the pro's / cons of each?
4) How many 3/4 air intakes are at the bottom and are there ball valves on all of them?
