This is (hopefully) helpful information that I use when building my stoves. I would highly recommend you look at https://www.instructables.com/id/Cool-Little-Miniature-Stove!/ or https://www.instructables.com/id/Aluminum-Bottle-Alcohol-Stove/ to build your stoves. This Instructable in intended for those of you who have already built their stoves and want to explore more options or make things "easier".
I have found this a very addicting hobby!
Thanks and enjoy your stoves.
Step 1: Soda Can Cutting Jig
I cut down a scrap piece of 1x2 and then used my bandsaw to cut a grove part-way through the block where I could insert the utility blade. I then used a drop or two of Loctite Super Glue to hold the blade in place.
I cut the block down to 2.25 inches in length. I made the cut with the bandsaw 1.25 inches from the bottom.
