Took the plunge today...
I ordered a brand new 85 gallon barrel from Grainger. Unlined open top 1.5mm thick all around.
Gonna order the weber 26" cooking areas and start looking at plans to build a fire basket.
Hopefully will have this guy done in a couple weeks for its first run before summer starts.
I heard some people lining the bottom with concrete so it doesn't rust through or burn out - is that a good idea? I'm going to put this guy on casters so I don't really care how heavy it'll get.
