发明名称 Alignment jig for attaching nocks on archery arrows
摘要 An alignment jig for use in attaching nocks on archery arrows is disclosed. The invention comprises a rigid base plate having a first support for the rear end of the arrow, at which the nock is to be mounted, and at least one additional arrow support spaced apart from and longitudinally aligned with the first support. A first reference line is arranged on the base plate and extends in a plane through the supports and at right angles to the plate, the first reference line being disposed at the opposite side of the first support relative the additional support or supports. A second reference line also extends in the plane and is parallel with the first reference line but is disposed on the opposite side of an arrow supported by the supports relative to the first reference line. A sight device, for aligning the pair of reference lines through the nock groove, is included, whereby the attainment of a proper longitudinal alignment of the nock with the end of the arrow can be checked with good accuracy.
