Abstract
An archery arrow is provided to include a shaft that is tubular and includes an exterior surface and an opposing interior surface, with an insert secured to the shaft. The insert can define a hole configured to join a component, for example, a broadhead with the arrow. The hole can be round and concentric with the exterior surface of the shaft, and in some cases non-concentric with the interior surface. The insert can be adhered to the shaft and later machined to define the hole to provide the concentricity of the hole and the shaft exterior or an associated outer diameter. When a component such as a broadhead is joined with the arrow via installation in the hole, the component can be centered relative to the shaft exterior. A related method of manufacturing an arrow is provided.
Claims19
A method of manufacturing an archery arrow, the method comprising:
- providing a shaft having a length corresponding to an archery arrow, the shaft including a first end and a second end, the shaft including an exterior surface that is cylindrical and an interior surface that is cylindrical, the exterior surface having an outer diameter and a first center, the interior surface having an inner diameter and a second center;
- installing an insert in the shaft adjacent the interior surface, the insert including a face disposed adjacent the first end;
- securing the insert to the shaft;
- and
- forming a hole in the insert through the face after said securing the insert to form a hole diameter and a hole center,
- wherein the first center and the second center are offset from one another by a distance of at least 0.001 inches;
- wherein the hole center and the first center lay along a common axis extending longitudinally through the shaft;
- and
- wherein the second center is offset from the common axis.
A method of manufacturing an arrow, the method comprising:
- providing a shaft that is tubular and round, and includes an exterior surface and an opposing first interior surface, the exterior surface centered on an outer diameter longitudinal axis, the opposing first interior surface centered on an inner diameter longitudinal axis, wherein the outer diameter longitudinal axis and the inner diameter longitudinal axis are offset from one another by a distance of at least 0.001 inches;
- and
- securing an insert to the shaft, the insert including an exterior insert surface that is round,
- wherein the insert is centered relative to the exterior surface of the shaft to balance the arrow.
A method of manufacturing an arrow, the method comprising:
- providing an arrow shaft that is tubular and round, and includes an exterior surface and an opposing first interior surface forming a bore, the exterior surface having an outer diameter and a first center, the first interior surface having an inner diameter and a second center, wherein the first center and the second center are offset from one another by a distance of at least 0.001 inches;
- installing an insert in the bore, the insert including an exterior insert surface that is round and an insert face;
- securing the insert fixedly to the arrow shaft;
- and
- drilling a hole in the insert through the insert face after the insert is secured fixedly to the arrow shaft along a hole longitudinal axis.
