CAVEMASTER DEMO PARTY
Bow Fire Drill Set
a small bow, drill, cap and board for starting fires
This is an advancement on the hand fire drill system. It consists of a board with a divot (the hearth), a thin stick (the drill), and a cap (a rock or less flammable piece of wood in which the drill pivots).
The slim drill stick is placed in a loop of the bow’s string. The cap is held on the drill to steady it. The bow is moved back and forth with a sawing motion.
