Supplies and Tools Needed for Alcohol Stove Construction
Can marking tool (one of the following)
2 cm and 3 cm wide block of wood
Balsa wood strips can be found at a hobby store in 1/8 and 1/2inch widths, which can be easily cut and stacked to desired heights. You can even screw on half of a utility knife blade (they'll snap in half with a little bending from two pliers) to a 1/2 inch width and use scotch tape to hold on additional pieces, which would allow you to easily change the position of your score/scribing line in 1/8 inch increments (1/16 inch if you use a 3/16inch strip).
rectangular piece of scrap aluminum flashing (see Card template - template is designed to be printed with Internet Explorer or Paint and other image programs may print magnified images) with holes at desired heights
book larger than 3 cm - place blade between pages of desired height, press down firmly with one hand and rotate the can with the other hand
piece of card with holes at desired heights
Adjustable Starrett Combination Square with scriber
Can Cutting Jigs made from pipes and plastic bottles can be used as demonstrated by Deems Burton. The 12oz aluminum drink can shown above fits very snuggly in the trimmed down plastic Gatorade bottle. Simply poke a hole in the plastic jig and use a marker, pin or knife to mark or score an even line by simply twisting the can. If you can't find a perfect fitting can/bottle combinations, you can use cardboard shims to get everything tight.
Can marker/scriber (one of the following)
Pen - the finer the better
Pin - used to scratch a line in the side of your cans
utility knife blade - used to score a line in the side of your cans
Can cutter (one of the following)
metal snips - these are overkill even for cutting tin cans and won't give you as smooth a cut as a good pair of sewing scissors
if you do a really good job of scoring with a knife blade, you can just apply a little pressure with your fingernail in the right spot to start a clean tear. If you are building an open jet stove, you will still need a pair of scissors or snips (a knife will work if that's all you have) to cut out the sidewall of the can for your inner cylinder
