Can Natural Draw Weights Vary Significantly?

Properties of the Stave

The natural draw weight of a bow is largely influenced by the properties of the stave, particularly its diameter, length, and type of wood. A stave with a diameter of 1.75 inches (44.5 mm) and a length of 60 inches (152.4 cm) will generally produce a lower draw weight compared to a stave with a diameter of 2.25 inches (57.2 mm) and the same length. For example, a bow made from a stave with a diameter of 2.25 inches will typically have a higher draw weight, as it requires more force to bend the stave.

Tillering and Sinew Backing

Tillering, the process of shaping and bending the stave to achieve the desired shape, also affects the natural draw weight of a bow. A bow with a more aggressive tiller will generally have a higher draw weight, as it requires more force to bend the stave. Additionally, the use of sinew backing can also impact the natural draw weight of a bow. A bow with a sinew backing will typically have a lower draw weight, as the sinew helps to absorb some of the force required to bend the stave.

Archer’s Technique

The archer’s technique also plays a significant role in determining the natural draw weight of a bow. An archer who uses a more aggressive shooting form, including a higher draw weight and faster release, will typically require a bow with a higher natural draw weight. On the other hand, an archer who uses a more relaxed shooting form, including a lower draw weight and slower release, will typically require a bow with a lower natural draw weight. In general, an archer should aim for a bow with a natural draw weight that is 10-20 pounds (4.5-9 kg) below their target draw weight to allow for a comfortable shooting form.
