What are Signs That A Bow Needs Retilling?

Indicators of Poor Tiller Alignment

When a bow is not properly tillered, the limbs are not in harmony with each other, which can lead to uneven arrow flight and loss of draw weight. Look for signs of uneven tiller alignment, such as a bow with one limb longer than the other, or a bow with limbs that are not parallel to each other. A properly tillered bow will have limbs that are symmetrical and parallel to each other, with the tiller (the curved section of the bow) aligned with the arrow rest.

The Process of Retilling a Bow

Retilling a bow involves realigning the tiller to restore proper limb alignment and symmetry. This can be done using various techniques, such as using a tillering jig to guide the tiller or using a combination of heat and pressure to shape the wood. The goal is to restore the natural curve of the bow, while maintaining its strength and stability. To retill a bow, start by measuring the difference in length between the two limbs, and then use a tillering jig or a combination of heat and pressure to realign the tiller.

Tips for Retilling a Bow

When retilling a bow, it’s essential to work slowly and carefully, as over-tilling can weaken the bow. Start with small, gentle adjustments and gradually work your way up to the desired shape. Use a combination of heat and pressure to shape the wood, and avoid using too much force, which can cause the wood to split or crack. Additionally, make sure to re-limb the bow after retilling to ensure that the limbs are properly aligned and the bow is stable.
