Quick Answer
You're experiencing difficulties generating heat with your bow drill due to poor friction, a faulty setup, or inadequate technique.
Poor Friction Setup
When using a bow drill, friction is generated by the rotation of the drill on the fireboard. A setup with too much distance between the drill and the fireboard can lead to inadequate friction. To correct this, ensure the drill is placed close to the fireboard, about 1/8 inch away, and the handhold is secured firmly to prevent movement.
Inadequate Drilling Pressure
Applying consistent drilling pressure is crucial for generating heat. Use your body weight to apply gentle but firm pressure on the drill. Aim for a pressure of around 5-7 pounds, which should result in a smooth, consistent rotation. Avoid applying too much pressure, as this can cause the drill to slip and lose friction.
Incorrect Bow Speed or Angle
Using a bow with the wrong speed or angle can also hinder heat generation. Shoot for a bow speed of around 100-150 revolutions per minute, which should result in a smooth, consistent rotation. Additionally, ensure the bow is positioned at a 45-degree angle relative to the drill, with the string striking the drill at the correct point of rotation.
