USING THE SPIN TESTERS
The Arrowsaw comes with 2 Spin Testers that allow you check the straightness
of arrow shafts.
1. Place the Spin Testers onto the Base. Using an arrow shaft as a guide,
position the Spin Testers within 1" of each end of the shaft.
2. Set the arrow shaft onto the Spin Testers.
3. Spin the arrow shaft in either direction by rolling your thumb perpendicularly
across the shaft at about the middle (FIGURE 12).
4. If the arrow shaft is true/straight, it will spin smoothly without any bounce or
excess movement.
5. If the arrow bounces or does not spin true/straight, the arrow shaft is faulty and
should be discarded.
