Cat Food Can Alcohol Stove
Requires a pot stand.
Slightly more bulky than other alcohol stove designs.
The most popular double jacketed alcohol stove is the Cat Can Stove by 2001 Triple Crown Roy L. TrailDad Robinson. There are a few variants, but the basic design remains the same – an inner ventilated can with fiberglass insulation for a wick encompassed by a larger diameter can with low lying ventilation. Fuel is vaporized and drawn upwards through a central opening where it ignites creating a low pressure zone that in turn draws fresh air in through the lower side vents.
This stove above is made of a 5.5oz and 3oz aluminum can (cat food) and a piece of fiberglass insulation. Six to eight holes are punched through the sides of each can with either a church key or a hole punch. Fiberglass insulation in placed in the smaller can and the two pieces are assembled as shown.
Acceptable fuels include denatured alcohol (ethanol), HEET (methanol) and others (see Fuel Options ). It requires a pot stand or rocks to hold the pot about 1-1.5inches for the top of stove.
Simmering is fairly easy to do, requiring that you block or partially block the inlet vents and/or limit the size of the exit port on top of the stove. You can block with the side inlet vents with a simmer ring and you can limit the size of the outlet port on top by placing a cutout can bottom from a second 5.5oz aluminum can with a hole (or several small holes) cut in it (or something similar – such as a piece of foil) on top of the stove.
Here is a miniature version made from a 3oz cat food can, 5.5oz V8 can and a circular piece of aluminum flashing JB Welded to the bottom to seal it and keep the inner chamber from shifting. Punching holes with a hole punch in lieu of a church key is mostly for aesthetics, but also allows for a better seal if you use a simmer ring around the circumference of your stove. This design is a modified version of John Bednar’s Turbo Cat II Stove ( Old Site ).
