Quick Answer
The shape of your spindle affects the efficiency of your fire bow drill. A thinner spindle is ideal for fire making as it reduces friction and allows for more consistent results. A spindle diameter of 1/4 inch or less is recommended.
Choosing the Right Spindle Material
When selecting a spindle material, consider its straightness, smoothness, and resistance to wear. A straight spindle is essential for a proper fire bow drill setup, as it allows for consistent tension and minimal wobble. Look for materials like straight-grained hardwoods, such as ash or hawthorn, which can be easily shaped to a precise diameter. Aim for a spindle diameter of 1/4 inch or less to minimize friction.
Spindle Preparation Techniques
To prepare your spindle for fire making, use a sharp knife or stone to carefully shave it down to size. Remove any knots or imperfections that can cause the spindle to bind or wobble. Use a piece of sandpaper or a file to smooth out the spindle’s surface, ensuring a consistent diameter and no splinters.
Final Checks and Adjustments
Before starting your fire bow drill, inspect your spindle for any signs of wear or damage. Check the spindle’s straightness and alignment with the bow’s string. Make any necessary adjustments to ensure a smooth, consistent ride. With a well-prepared spindle, you can focus on developing a consistent drill stroke and generating the friction needed to ignite your tinder.
