Haha, thought I might get a comment about the butane stove. The charcoal chimney has quite a gap from the bottom to the first bit of charcoal, so I can't see it getting any hotter than having a pot sitting on the stove. Anyway, we'll see how it goes Look, I don't think it's SUPER important to have a food grade drum, but they were easy for me to get my hands on, cheaply, so I did. If it were me and I had no option of food grade, I'd be looking for the least nasty contents possible. Motor oil would be an ok option. Just stay away from nasty solvents and stuff, and give it a REALLY good hot burn off. Yep, repainted the same satin black as the drum. The 25mm inlet on the front is handy for getting temperatures up quickly, but it's not essential.
