Quick Answer
You should replace your fireboard in a bow drill every 5-10 uses, or sooner if you notice it becoming worn or developing cracks.
Choosing the Right Fireboard Material
When selecting a fireboard, look for a piece of wood that is at least 1 inch thick and has a smooth, even surface. Softwoods like pine or fir work well, as they tend to split more easily than hardwoods. Avoid using pressure-treated or resin-infused wood, as these can be difficult to drill and may contain chemicals that can be toxic when burned.
Preparing the Fireboard
To prepare the fireboard for use, carve a small notch in the top surface, about 1/4 inch deep and 1/4 inch wide. This notch will serve as the fire starter. Next, draw a series of parallel lines across the notch, spaced about 1/8 inch apart. These lines will help guide the drill and create a consistent, even surface.
Signs of Wear and Replacement
Even with proper care, a fireboard will eventually wear out and need to be replaced. Look for signs of wear, such as cracks, splits, or a rough surface. If you notice any of these signs, it’s time to replace the fireboard. Try to replace it before it becomes too damaged, as this can make it difficult to create a viable fire starter.
