Awesome Matt! I'm considering building my first rocket stove this summer, without any hands-on experience or guidance, just going by Ianto's book. For safety I was thinking of making it an outdoor bench/grill much like this one. Questions: Is the cobb on your bench protected in some way or do you expect it to hold up to the rain in it's own? What did you use as a foundation under your stove and bench, if any?
