Haha. Ok, I guess that sounds crazy but I'd really like to know if anyone has ever tried it. I'm thinking about a cement mixer with a polyurethane barrel without obstructions inside like this: http://www.marshalltown.com/Mixers.aspx#wheelbarro
It looks like it would mix a 20 or 30 lb batch of dough quite easily, and be easy to clean up.
Maybe someone in another country that doesn't have such strict rules about what they can use?
I'm actually thinking of ordering one and trying it out, but I'd rather read about someone else doing it. If it failed,
I could always use it for home improvements
