Abstract: An arrow and method of making it. The arrow has a hollow arrow shaft, a single piece adaptor having one end with an outer diameter and a cylindrical bore with an inner surface adhesively engageable about a first end of the shaft and an externally threaded opposite end. An inclined surface surrounds the externally threaded end and tapers inwardly from the outer diameter of the one end towards the bore. The inclined surface has a diameter greater than that of the external threads. The external threads and inclined surface receive and retain an arrow point with internal threads and inclined surface so that impact forces are not transmitted to the inner surface of the shaft. A balance pin has a shaft portion received in the arrow shaft, and a head portion interconnected to one end of the balance pin shaft portion. The head portion has a diameter greater than the shaft portion outer diameter and smaller than the inner diameter of the cylindrical bore.

Abstract: An arrow end adaptor and a balance pin for an arrow and a method for making the same. The arrow comprising a ferrule having a large enough inner diameter to be placed over the arrow shaft, and further having an exterior threaded end whose diameter is smaller than the diameter of the arrow shaft. The point cap is designed such that an arrow point having interior threads may be attached to the exterior threaded end of the point cap. The balance pin is designed to have a head at one end that may be affixed to either a target point or a point cap and a shaft end that may be inserted into the arrow shaft.

Abstract: A fence post and wire support for electric fences wherein the post is made of unidirectional glass fibers in a plastic resin and has a T-shaped cross section. The resulting structure is light but rigid, and has flat surfaces which eliminate the need for an anchor plate. A number of wire-like clips are adapted for crimping around the post or for resiliently engaging the post to form a wire support. The wire-like clips are designed to cooperate with the T-shaped cross section of the post to provide a secure mounting thereto. Alternatively, a rubber-like wire support having two ring portions which fit snugly around the post, and having a hinge portion joining the ring portions may serve as the wire holder.
