I am really impressed, and very grateful for the pictures and video that you posted. I've often wondered about barrel stoves.

One thing- and it may not even apply: don't burn stuff like poison ivy, poison oak or poison sumac. It's a real pain to keep it separate when clearing the yard and burning all the yard debris, but the oils and particulates in those plants will float up the chimney and get EVERYWHERE, including in the air you breathe. (We had a cast iron wood stove when I was growing up.)
