Use this patent-pending tool to precisely set up your Bitzenburger fletching jig to the desired helical (or offset) angle. The wrap shows angles from 0 - 6 degrees left or right and is attached to a 7” section of 0.204 ID arrow and includes a nock. Just place an arrow in the clamp, turn the nock so that the bottom corner of the vane is in the crosshair as shown and adjust the dials on the jig. This works with the straight and helical clamp. The helical clamp actually puts the vane on straight, it just follows the curvature of the arrow better. Simple, precise, and highly effective.
