As the sharp wood rotates against another surface, the friction generates heat. If used for fire-starting, the heat eventually becomes high enough to ignite small particles (like wood dust) and start a fire. In drilling, this heat and mechanical action carve into the wood to create a hole. Mechanical Advantage: The bow provides a mechanical advantage, allowing the operator to rotate the drill more quickly and with consistent pressure using less energy. The rope scrolling action helps maintain constant rotation in alternating directions (clockwise and counterclockwise). Force
