This is (hopefully) helpful information that I use when building my stoves. I would highly recommend you look at http://www.instructables.com/id/Cool-Little-Miniature-Stove!/ or http://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.
Step 2: Cutting Can
I stand the jig with the blade at the highest point first to cut the can down for the stove.
Step 3: Cutting Windscreen
After I finish cutting the can for the stove, I flip the jig over and remove the top of the can so I am left with an aluminum tube. I then cut the tube up one side so I have a "sheet".
Step 4: Folding Windscreen
I use a pliers with a smooth lip to fold over a little bit of the edge all around to make sure there are no sharp edges. This also gives the can some strength to keep it standing while holding its shape.
