Why Is Tillering Crucial In Bow Making?

Understanding the Importance of Tillering

Tillering is the process of selectively removing wood from the stave to achieve the desired shape and dimensions. This is typically done by hand, using various tools such as drawknives, spokeshaves, and sandpaper. The goal of tillering is to create a smooth, even surface, with consistent thickness and a well-defined edge.

Techniques for Tillering

When tillering a stave, it’s essential to follow a systematic approach to ensure accuracy and consistency. Start by marking the desired shape and dimensions on the stave, using a combination of measurements and visual inspection. Next, use a drawknife to carefully remove wood from the stave, working in small increments and checking the shape regularly. Use a spokeshave to refine the edges and smooth out the surface, and finish with fine-grit sandpaper to achieve a high-gloss finish.

Tillering for Sinew Backing

For bows that will be sinew backed, tillering is particularly crucial. The sinew backing process relies on the stave’s internal structure and shape to provide a solid anchor for the sinew. A well-tilled stave will provide a smooth, even surface for the sinew to adhere to, while also allowing for even stress distribution and minimizing the risk of failure. To achieve optimal tillering for sinew backing, focus on creating a stave with a consistent thickness of 1/4 inch (6 mm) or less, and a well-defined edge that is smooth and even.
