Quick Answer
The correct reflex in a bow is identified by holding the bow vertically and observing how the limbs bend, looking for a smooth, even curve without kinks or sharp angles; ideally, the limbs should bend in a gentle, smooth S-shape.
Inspecting the Bow’s Reflex
When inspecting a bow’s reflex, look for a consistent and even curve in both limbs. This can be achieved by holding the bow vertically and observing how the limbs bend. A good reflex should be smooth, with no sharp angles or kinks. Ideally, the upper limb should be slightly more convex than the lower limb, forming a gentle S-shape. This S-shape should be consistent throughout the length of the bow, with no areas of uneven bending.
Measuring the Reflex
To quantify the reflex, measure the distance between the bow string and the upper limb at the midpoint and at the ends of the bow. A good reflex should have a consistent difference of about 1/8 inch (3-4 mm) between the midpoint and the ends. This indicates a smooth, even curve. If the difference is greater, it may indicate a kink or uneven bending in the limb.
Techniques for Achieving the Correct Reflex
Achieving the correct reflex requires careful tillering of the bow stave. This involves gradually shaping the stave to create the desired curve. To do this, use a combination of sanding and scraping to remove wood and create a smooth, even surface. It’s essential to work slowly and carefully, checking the reflex frequently as you go. This will help you achieve a consistent and even curve throughout the length of the bow.
