MATERIALS THAT I USED
>I found a hand-cranked garden insecticide powder dispenser at a garage sale. They are commonly used to dust plants with products like 5% Sevin powder. Let's call it a "blower." It was gear-driven and had a friction-fit output pipe about 12" long and 1.5" in diameter.
> 1 lb. and 3 lb coffee cans. (Not that they hold that much any more and not that you are restricted to such cans -- but use steel cans.)
> 1/2" opening hardware cloth (heavy wire screen) large enough to make a grate in each can.
> metal clothes hangers or similar wire.
(I suppose that any cranked blower or even a bellows could be used)
TOOLS THAT I USED
>side-cutting pliers
>small tin snips
>10d nail
>hammer
>12" piece of 4x4 with one edge trimmed to create 1/2" flat instead of sharp corner (to support sides of can when punching holes with nail)
CONSTRUCTION (very tough!

)
>First, I cleaned the blower out REAL well with soap and hot water.
>Then I cut a hole in a coffee can to fit the output pipe from the blower SNUGGLY. The height of the hole was dictated by the height of the output pipe when the blower was resting on the ground. You need clearance so the crank handle can go around.
>Then I cut the hardware cloth onto circles to fit inside the cans.
>Cut three lengths of hanger wire 1" longer than the diameters of the respective cans. These lengths of wire are inserted through pairs of holes punched opposite each other in the sides of the respective can, and they act as supports for the hardware cloth grate. NOTE: You want the grate to fit as far down in the can as possible so punch the holes accordingly.
>Place the lengths of wire through the holes and bend 1/2" over to secure in place.
>Insert wire grate from top.
>Use nail to punch holes 1/2" apart around top of side of can about 1/4" from edge and enlarge to 1/4" by inserting and rotating one point of the tin snips (Or you could use a "church key" to make openings in the top of the side of the can).
Fuel (anything that burns) goes in can on top of grate. Light. Insert and blower and turn crank. Cook. Boil. Melt glass. Great tool for "starting" charcoal.
