The best choice then is likely to find an older barrel( ie. thicker materiel) or make your own. On the idea of making your own, I am curious on what would be considered the ideal thicknesses of the barrel. Should the top be thicker to retain more heat, not only for better burn but a better cook surface as well? Should the sides be thicker or thinner to radiate heat better? Erica mentioned that if someone knows how or has the ability to make barrels to get a hold of them so perhaps they have some certain specs in mind.
. But they will smoke a some and you have to tend them every 30 seconds or so. Four inch cans are better for the inner chamber and fuel input. Adding another can on top, double the heat risers height will get rid of most of the smoke. I have used one to camp with and cook on many a time.
