Thanks for sharing the details on the materials, tools, and techniques you used for building your stoves. I used both straight and right angle pneumatic die grinders a lot when I got into aircraft maintenance, though often just on general projects, not necessarily on the aircraft themselves. Those light, compact, pneumatic grinders sure are handy tools to have!
I have a couple of those nifty little commercial folding sheet iron stoves and find them both useful and interesting. The first ones that I know of were Chinese imports, but they are something the Chinese can make well, not to mention cheaply. Sportsman's Guide sold them, then they cut the price in half and I bought some more to give to my friends. Now I've seen them advertised again in Backwoodsman Magazine, for about $15 apiece I think. Their design is clever and it folds up like a puzzle, but with all the pieces still connected. They burn twigs, pine cones, charcoal, wads of paper, dried camel dung, and whatever else you care to stoke them with.
