This specification covers the method of determining and designating the balance point location of an arrow assembly for use with an archery bow. The base for determining the percentage location of the balance point of the arrow assembly shall be the ATA (Archery Trade Association) arrow length. When the balance point of the arrow is determined, the arrow assembly shall be complete with all components, including the arrow point in place and mounted securely ready for shooting. In determining the balance point, the arrow assembly shall be placed on a knife edge and moved longitudinally until perfect balance is achieved. The FOC (front of center) shall be measured as follows: from the bottom of nock slot, measure the distance from the bottom of the nock slot to the balance point; or from the front of the shaft assembly, measure the distance from the designated point to the balance point. The percent FOC shall be calculated using the specified formula. The following arrow assemblies are illustrated: (1) arrow assembly employing an interchangeable point insert (2) arrow assembly having the front end of the shaft tapered or swaged, (3) arrow assembly incorporating an outsert, and (4) arrow assembly with a head that has an integral cylindrical socket.
