The idea for this project was born from trying to get our campfires started with kindling and wood so wet we couldn't get them to burn with dry paper. Sure charcoal lighter would work but where's the fun in that?
Please don't be misled by the term Moose/Bear Repellent, I only used it to create more interest. It probably wouldn't deter a bear that was intent on inflicting harm. If anyone wishes to visit Alaska to enjoy the great outdoors, I would recommend some sort of bear deterrent. Be advised a big ol' can of pepper spray isn't always effective, they have even been seen licking it from the ground. Making plenty of noise or an occasional blast on a portable air horn while you're hiking will keep surprise encounters to a minimum. As for the moose, beware, they usually aren't afraid of anything and would love a chance to bully you for your snacks, or for no reason at all.
Some words of caution: Be safe, have a fire extinguisher or bucket of water nearby and someone else there in case whats burning is you. Never operate indoors. You wouldn't pee up a rope or spit into the wind, it'll get ya if you do, so don't use it when the wind is blowing.
Materials: All materials are available at Lowes or Home Depot except the butane refills and birch plywood, which can be found at tobacco shops and craft stores respectively. Total estimated cost $50-$60 US.

Step 1: Choose the fuel supply and material for the fuel chamber
PIC#2 I checked a copper tubing handbook and found the size of copper tube that's inside diameter most closely matched the outside diameter of the butane supply I was using, which happens to be 1-1/2 inch type "L" tubing. I cut an eight inch length of the 1-1/2" type "L" copper tubing. I Purchased a 1-1/2 inch end cap to fit over one end of the tube and another 1-1/4 inch cap to fit inside the tube.
PIC#3 The end of the nozzle on the butane supply is stepped.
PIC#4 A hole for the butane nozzle must be placed in exact center of the 1-1/4 inch end cap. To find center I painted the inside of the cap with a black marker and allowed the ink to dry.
PIC#5 Coiled up scotchbrite pad rotated gently inside the 1-1/4 inch cap to remove the ink.
PIC#6 If done as described you should have a mark dead center. Drill that mark with a 1/16 inch bit followed by a bit just large enough for the butane nozzle to pass through until it contacts the first step on the butane nozzle.
