Troubleshooting And Tips

Taming crooked shafts

The adjustability of the Spinrite Crester will allow you remove some of the wobble created by a less than perfectly straight shaft. While the Spinrite Crester will not straighten your arrow shaft, it can temporarily reduce the wobble in the arrow shaft while you apply your paint making your cresting lines straight and even. There are no set directions for reducing the wobble. It is a trial and error system of adjustments. Minor adjustments often create better results than large changes. Play with the adjustments and see what works for you. Here are some of the adjustments that can be made to help. This is not a definitive list. The adjustments are listed in the order that have shown to have the most effect.

Move the idler arm in towards the center.

Slide the center support rollers to one side or the other.

Move the center support rollers under the idler arm's new position.

Move the arrow stop in or out to support a different section of the arrow.

Move the motor arm in towards the center.

See video for some examples.

There may be times when your arrow does not spin as expected. Here are some tips to try if you encounter any issues.

Make sure all of the idler rollers are free and spinning. The side rollers can get pinched against the side brackets causing them to bind. Slide the rollers away from the side. This will provide clearance for the rollers to spin freely.

There are occasions when the center rollers will not make arrow contact and spin. Test a non-spinning roller with your finger to be sure it will spin if it is in contact with an arrow shaft.

Excess tension on the idler arm can cause errant spinning of the arrow shaft. Generally you want the tension spring slightly left of the center of the gap between the motor arm and idler arm. This is a general adjustment some arrow shafts may need the tension closer to the idler arm.

Drive Tire Wobble:
The drive tire wobbles side to side.
This is caused by the gearbox on the motor.
While horrible looking, it has no effect on the crester performance.
(We hate it too)


To load and unload arrows while running:

Place arrow nock end against arrow stop and insert under idler arm, then under the motor arm

You want to keep a "V" angle with the motor end furthest away from the crester.
To remove reverse the process, remember to keep left of the shaft furthest from the motor

The OVERVIEW video shows this well at about the 1 minute mark.

Keep the left side idler rollers to the left of the drive tire. Any further right than the edge of the motor with these idlers will cause poor performance.

Adding a rear pattern:
Cut a piece of paper, 3x5 card (or larger) to fit from the bar to barely above the arrow shaft. Tape in place. You may want, or need, to add a notch for the idler arm as shown.
