ABSTRACT:
An improved arrow fletching jig for use with a multi-vane fletch, preferably a two-vane fletch, having a bridge between adjacent vanes comprises an upstanding jig block having an upper surface adapted to support an arrow shaft, and also the bridge of such multi-vane fletch against the shaft for proper bonding and fletching. The block upper surface preferably is grooved and inclined down towards a vertical post spaced from the block and bearing preferably vertically adjustable means for releasably holding the nock end of the arrow to be fletched. The spacing between the post and block can also be adjusted to accommodate various arrows and fletches. The sides of the block preferably diverge from the block's upper surface at an angle about equal to the angle between adjacent fletch vanes when the vanes are properly aligned with the shaft. Thus, the block sides support these vanes while the block upper surface supports the bridge between the vanes. A strap or the like may be used to press the shaft into the fletch bridge when overlying it on the block upper surface. The device is simple, inexpensive, durable and highly efficient and is adjustable for fletches of the type described.
