I have made several alcohol stoves. So far I made one cat can stove out of a tuna can that was to side to fit my cup on, and one pop can stove that just did not go together very well. I also made one of the penny type alcohol stoves but the PITA way you have to prime it turned me off to it even though it seemed to work OK.

I have a smaller can that may work as a cat stove. It is about the right size, but it is thicker steel so I will have to drill it instead of using a paper punch.

I also want to make another of the double walled can stoves, but do a better job of it. They seem to be the best of the DIY alcohol stoves over all.
