This site (http://zenstoves.net ) has gobs of directions for different types of alcohol stoves. The cat can stove has been my favorite for a long time, even to the point that my high-priced white gas backpacking stoves haven’t been on a trip with me since 2000. Lots of good safety information as well as fuel information.
‘Seen the Russian YouTube, where he opens a can in a minute by “sanding-it” against a concrete block?
