Off the wall question, I know, but any recommendations for "sourcing" used brake drums from trucks. Neighbors have two they are using for flower planters / corner markers and I though "Cool, but they probably would work well for braziers. After all, they're a cast iron, which will handle heat relatively well, you can make a small fire in them and they'll radiate quite nicely. I mean, what's the difference between them and a "son of Hibachi".
So, where's a good place to "source" a set?
