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 the 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
