• Bow. The bow is a resilient, green stick about 2.5 centimeters (3/4 inch) in diameter with a bowstring. The type of wood is not important. The bowstring can be any type of cordage. Tie the bowstring from one end of the bow to the other, without any slack. Figure 7-8. Bow and Drill 7-30. To use the bow and drill, first prepare the fire lay. Then place a bundle of tinder under the V-shaped cut in the fire board. Place one foot on the fire board. Loop the bowstring over the drill and place the drill in the precut depression on the fire board. Place the socket, held in one hand, on the top of the drill to hold it in position. Press down on the drill and saw the bow back and forth to twirl the drill (Figure 7-8). Once you have established a smooth motion, apply more downward pressure and work the bow faster. This action will grind hot black powder into the tinder, causing a spark to catch. Blow on the tinder until it ignites. 7-31. Primitive fire-building methods are exhausting and require practice to ensure success. If your survival situation requires the use of primitive methods, remember the following hints to help you construct and maintain the fire: • If possible, use nonaromatic seasoned hardwood for fuel. • Collect kindling and tinder along the trail. • Add insect repellent to the tinder. • Keep the firewood dry. • Dry damp firewood near the fire. • Bank the fire to keep the coals alive overnight. • Carry lighted punk, when possible. • Be sure the fire is out before leaving camp. • Do not select wood lying on the ground. It may appear to be dry but generally doesn't provide enough friction. Chapter 8 Food Procurement 68
