For the base, neatly cut one can about 1 1/2" (3.5cm) from the bottom. For the
top, cut the other can about 1" (3.5cm) from the bottom.
Drill a number of holes (18-30) around the edge of the top and in the center as shown;
use a 1/16" drill bit.
Fill the base with Perlight, just more than half full.
Make 6-8 vertical cuts around the top. Make the cuts up to but not over the rounded
edge. Slowly press the top into the bottom. (A small board can help make it even.)
Fill the stove about half full of alcohol. Light the burner by slowly moving a match or
lighter over the edge of the burner. Note: If it does not stay lit, tip
the burner up to leak some fuel into the rim and relight. Hold it until it stays lit or
gets too hot.
Cut and straighten a coat hanger. Use a fine sandpaper to remove any paint or coatings.
Bend the coat hanger wire (or any large gauge wire) into a shape that will hold a pot a
few inches above the burner (see the example). Note: with a little
imaginations you can create a number of stove bases
