Friction-Based Fire Making
Rubbing two sticks together is likely the oldest of all fire-starting techniques, and also the most difficult. Besides proper technique, you have to choose the right wood for the fireboard and spindle. Sets made from dry softwoods, including aspen, willow, cottonwood, and juniper, are preferred, although a spindle made from a slightly harder wood, combined with a softer fireboard, can also work. The friction of the spindle against an indentation in the fireboard grinds particles from both surfaces, which must heat to 800 degrees F before a glowing coal forms. This must then be transferred to tinder and gently blown to life.
Hand Drill (picture)
Using a hand drill is one of the simplest friction methods, but high speed can be difficult to maintain because only the hands are used to rotate the spindle. It works best in dry climates. Step One Cut a V-shaped notch in the fireboard, then start a small depression adjacent to it with a rock or knife tip. Set a piece of bark underneath the notch to catch the ember. Step Two Place the spindle, which should be 2 feet long, in the depression and, maintaining pressure, roll it between the palms of your hands, running them quickly down the spindle in a burst of speed. Repeat until the spindle tip glows red and an ember is formed. Step Three Tap the fireboard to deposit the ember onto the bark, then transfer it to a tinder bundle (see “Tinder Bundle” on page 56) and blow it to flame.
Two-Man Friction Drill (picture)
Two people can do a better job of maintaining the speed and pressure needed to create an ember using this string variation of a friction drill.
- Step One Have one person apply downward pressure to the drill while the other uses a thong or shoelace to rapidly rotate the spindle.
Fire Plough (picture)
This produces its own tinder by pushing out particles of wood ahead of the friction.
- Step One Cut a groove in the softwood fireboard, then plough or rub the tip of a slightly harder shaft up and down the groove. The friction will push out dusty particles of the fireboard, which will ignite as the temperature increases.
Pump Fire Drill (picture)
The Iroquois invented this ingenious pump drill, which uses a flywheel to generate friction. The crossbar and flywheel are made of hardwood; the spindle and fireboard are made from softwoods (as in the hand drill).
- Step One Bore a hole in the center of a rounded piece of hardwood and force the spindle in so that it fits tightly. Select wood for the crossbar and bore a larger hole that will slide freely on the spindle.
- Step Two Attach the crossbar to the top of the spindle with a leather thong or sturdy shoelace.
- Step Three Wind up the flywheel so that the thong twists around the spindle, then press down. The momentum will rewind the crossbar in the opposite direction. Repeat until friction creates a glowing ember.
Bow Drill (picture)
Of all the friction fire-starting methods, the bow drill is the most efficient at maintaining the speed and pressure needed to produce a coal, and the easiest to master. The combination of the right fireboard and spindle is the key to success, so experiment with different dry softwoods until you find a set that produces. Remember that the drill must be as hard or slightly harder than the fireboard.
- Step One Cut a notch at the edge of a round impression bored into the fireboard, as you would for a hand drill. Loosely affix the string to a stick bow, which can be any stout wood.
- Step Two Place the end of a wood drill the diameter of your thumb into the round impression, bear down on it with a socket (a wood block or stone with a hollow ground into it), catch the drill in a loop of the bowstring, then vigorously saw back and forth until the friction of the spinning drill produces a coal.
- Step Three Drop the glowing coal into a bird’s nest of fine tinder, lift the nest in your cupped hands, and lightly blow until it catches fire.
Spark-Based Fire Making
Human beings have been starting fires from sparks since the days of the cave dwellers of the Paleolithic era. It is still a vital survival skill for modern hunters and fishermen to learn. If conditions are wet or windy and matches are extremely difficult to light, a glowing spark in tinder uses wind to its advantage to burst into flame.
Flint and Steel (picture)
Striking the softer steel against the harder flint will produce sparks to flame your fire. The curved steel striker provided with flint and steel kits is easiest to use, although with some practice you can produce sparks by using the back of a carbon-steel knife blade. (Stainless-steel knives are usually much too hard to shave sparks from.) An old bastard file or an axe head will also work.
- Step One Grasp a shard of hard rock, such as flint or quartzite, between your thumb and forefinger with a sharp edge protruding an inch or two.
- Step Two Tightly clamp a piece of your homemade char cloth or a lump of birch tinder fungus under the thumb holding the piece of flint. Grasping the back of the striker, knife blade, or file in your other hand, strike a glancing blow against the edge of flint, using a quick wrist motion. If you’re using an axe, hold the head still and sharply strike the flint near the blade, where the steel is harder. Molten sparks from the steel will fly off and eventually be caught by an edge of the char cloth, causing it to glow.
- Step Three Carefully fold the cloth into a tinder nest and gently blow on it until it catches flame. Another option is to use a magnesium-and-steel tool, which is an updated version of an ancient method that creates a strong shower of sparks. The advantage of this method is that the magnesium shavings flame briefly at an extremely high temperature, eliminating the need for char cloth or tinder fungus.
- Step One Using a knife blade or striker, shave a pile of magnesium flecks into a nest of tinder.
- Step Two Strike the steel edge of the tool with the back of a knife blade or the scraper provided to direct sparks onto the tinder.
- Step Three When the tinder starts to smolder, gently blow on it until it bursts into flames.
