ABSTRACT:
An arrow straightener for testing and straightening bent arrow shafts is provided with a pair of arrow supports, each of which has a bearing surface that is rotatable about an axis normal to a vertical plane through the longitudinal axis of an arrow positioned on the supports to maintain the bearing surface in flat contact relation to the arrow shaft, a press mechanism between the supports for applying a straightening pressure on the arrow shaft, and a deflection indicator with a feeler that extends through the press mechanism into contact with the shaft, the feeler being movable independent of the press but located at a point central to the pressure applying surface. The apparatus also includes a scale, indicator, weighted body, and spacer for testing the spine strength of wooden arrow shafts.
