Nock & Arrow Rest Position:
Bow tuning is more than just a good idea, it is required if you hope to reach your potential as an accurate bow hunter.
Nock set position:
Installing your nocking system should be done with great care.
Position the nock locator (which ever style you choose) so that the top of the arrow’s nock will be roughly 3 to 5mm above the center of the arrow rest hole. As shown in the picture below.
You need to use a simple T-square to assure that you are in the right place.
If you are using a crimp on nock set, the bottom of the nock set should be at this position.
If you are using a nocking D-Loop, the bottom of the upper knot should be at this position.
The same thing goes if you will be using a metal D-loop.
Vertical Rest Position:
Most compounds will shoot best when the arrow crosses the center of the arrow shelf or arrow rest hole. You accomplish this by moving the arrow rest support arm up or down until you achieve the desired results.
Be sure you are holding the bow so that the arrow rest hole is at eye-level when making this adjustment so you get as close to center as possible.
You might have to make a few minor tweaks before its perfect.
Remember your arrow must not be 90 degrees with the string; the angle must be slightly smaller than 90 Degrees.
When you look at your bow from the side the arrow must raise a little bit as you move from the rest to the string about 3 - 5mm should be fine.
Horizontal Rest Position:
When setting up for a release aid, position your arrow rest so that the arrow is right in line with the forward movement of the string.
If you release with fingers, your arrow should be pointed slightly to the left of this line (for right-handed shooters).
There are several ways to go about setting-up the horizontal (left-to-right) position of your arrow rest.
The easiest is to eyeball the resting arrow from above with the arrow nocked into position and resting on the arrow rest. Set the bottom cam on the floor and hold the top axle between your index fingers.
Unless one of your arms is shorter than the other, the bow should now be pointing more or less straight in front of you.
Now check the line of your arrow with the line of the string and the center of your bows riser.
If needed adjust the rest left or right until the arrow is in line. While this is not as precise as using a device to accurately measure the bow’s center shot position, it will get you very close very quickly.
You can also put a long stabilizer on your bow and, again while looking down on the bow, adjust the rest in and out until the arrow is parallel with the stabilizer. It likely won’t line up right on top of the stabilizer, but if the stabilizer hole is drilled correctly, it should be parallel.
This is a great starting point but you need to paper tune your bow to be sure your arrows are flying like they should. Paper tuning your bow will show you all you need to know about tuning your bow properly, setting your nocking position up or down or adjusting your arrow rest position.
The tears in the paprer will show if the arrow rest should be moved left or right in some cases.
