Compound bow tuning is an art that possesses a tint of science having its deep roots found in the earliest archery. This sport has earned great interest of the people all over the world in spite of its tricky and mind shaking techniques. Normally, when people tend to get involved in bow tuning, they find various hurdles like they may attain faulty bow hand gripping or may the differences in arrow stretching.
All such queries leads to the drowning interests of the individuals. Well, it won’t be so anymore as we are providing you a detailed guideline for bow tuning. After going through this article, we are very sure that most of your troubles regarding this sport would definitely vanish and you would love yourself to get indulge over here.
TARGETED POINTS OF BOW TUNING:
Without any resistance, let us give you a precise guideline of bow tuning. Here, we are mentioning the steps that should be followed to get a clearer view of this sport.
Evaluate the String and Cables:
When you break out your bow for the new season, the first thing to do is have your bow-shop pro check the strings and cables, which deteriorate and stretch over time. This can result in rotated cams, shifted nocking points, de-flexed limbs, and even a potentially dangerous shooting situation. Ever seen a bow blow up when the string breaks? We have. It’s not pretty. Strings and cables will show some wear from hard use on the outside, but they actually deteriorate fastest from the inside out. Most new strings will last three to four years. If you need a new one, you can either order from the factory or have your pro make a custom one.
Press and Twist:
Strings and cables that are a year or two old may not need replacement, but chances are they have stretched enough to slightly rotate the cams (or cam) and cause some timing issues, not to mention shifting your nocking point and peep sight. Twisting of the cables and string is the first step in tuning a bow and bringing it back into factory spec, You add twists to create more tension on the limbs and cams.
Check Your Draw Length:
We would guess that 70 percent of the guys who have keen interests in Compound bow tuning, shoot a bow that’s a bit too long for them. Everybody wants that extra half-inch of draw length for increased speed. But shooting a bow that’s too long can cause problems with shooting form and can also lay the groundwork for problems with your arrows–namely, with the spine (more on that later). If you have any doubts, double-check with your local pro to be sure your draw length is correct, and that you know the exact length of the arrows you’ll be shooting.
Find the Center Shot:
With the strings and cables set, it’s time to perfectly align your nocking point and arrow rest. This is called finding the center shot. It can be done with a laser center-shot tool, or an old-fashioned bow square, which is what normally people use. There are intricate methods of measuring across the limbs to find the center shot, but it’s complicated, and honestly, we have never found it necessary. We usually suggest using the bow square to get your nocking point and rest aligned and then make fine adjustments when paper-tuning (more on that in a bit, too).
Align the Peep:
Generally, people do not realize that they are bending their necks to look through their peeps sight. Later they need to set up a new bow as they got to know that their peep had been too low on the string. By setting the new peep higher, they can immediately begin shooting better. You can get away with shooting your bow a few times before the peep is served into the string. Experiment with moving it up and down, and then serve it in so it stays tight only after you’re sure it’s where you need it. The fastest way to get your peep alignment correct is to close your eyes, draw the bow, settle into your anchor point, and then open your eyes, You should naturally be looking right through the peep. If not, move it.
Find the Arrow Spine:
The most common problem that we observe is hunters shooting an incorrect arrow spine. “Spine” is simply the arrow’s stiffness; the lower the number, the stiffer the arrow. For example, a 400-spine arrow is more flexible than a 340-spine arrow. All arrows flex when coming out of the bow before recovering and flying to the target. Slower bows–those with light draw weights, more rounded cams, etc.–impart less flexing on the arrow and shoot best with a flexible spine. Faster bows require a more rigid spine, or the arrow will flex too much. Most arrow manufacturers have spine calculators on their websites.
Choose a Fletching:
Not long ago, arrows fletched with feathers or long vanes with aggressive helical arrangements resulted in better arrow flight, especially with broad heads, for compound shooters. But that has changed. Short, stiff vanes like Blazers now provide outstanding arrow guidance and are rigid enough to withstand repeated shooting through capture-style rests, such as a Whisker Biscuit. They’ve become the standard for most Compound bow tuning arrows.
Find the Front of Center:
An arrow’s flight is most stable when most of its mass is Front of Center (F.O.C.). Most experts recommend an F.O.C. of 7 to 11 percent. That number is calculated by first finding the balancing point of the arrow (with the point on) and measuring it from the nock grove. Then you subtract the center of the arrow (overall length measured from the nock groove to the end of the shaft, divided by two) from the balance point and divide that by the overall length. And finally, multiply by 100.

Weigh and Spin Test the Arrows:
With your arrows crafted, the final step before shooting them is to weigh and spin-test each one. Obviously, you want them all to weigh the same. A couple of grains difference won’t affect much and is common, but much more than that can create problems. Spin testing is simply checking the arrow’s straightness. You can detect a problem by rolling your arrow across a flat surface narrow enough for the shaft to overhang on both ends. Wobbling on either end is not good.
Before hitting the range for a sight-in session, you should do a paper-tuning check. A paper tune is a good, final way to double-check your center-shot and make sure you don’t have issues with your arrows. If you know everything is set up correctly with your bow, a bad tear on the paper can reveal problems. But it’s not fool-proof. It’s possible to get a perfect tear, even if something is out of whack on your Compound bow tuning.
That’s why all the preliminary checks above come first. We would also stress upon the importance of shooting the bow yourself, rather than letting someone else shoot it. For paper-tuning to work, you have to release the arrow flawlessly; little mistakes in form can also cause a bad tear. Shoot the paper several times, and when you’re positive you’re making good shots and getting perfect bullet-hole tears. Chances are the bow and arrows are tuned up and ready to go.
Sight In with Field Points:
First, make sure you’re on the target at 10 yards, and then begin your sight-in session at 20. Some people like to shoot five-arrow groups. some like to shoot three, as it takes some fatigue out of the equation. Dial things in perfectly at 20 before stepping back to 30, and then 40. As a rule, we would only ask you to sight in at one range per shooting session–again, to reduce fatigue. You’re not really practicing right now so much as you’re ensuring your bow is set up for practice.
Stretch a piece of tape vertically on the center of your target, and add a small dot for aiming at the top of the strip. Shoot that dot at 20 yards. Back up to 25, aim at the same dot with the same pin, and shoot another arrow. Back up to 30 yards and repeat. Do the same thing clear out to 45 or 50 yards. Ideally, your arrows, while hitting progressively lower, should be in line vertically. If you notice a trend of all the arrows gradually “walking” to one side or the other of the tape, a fractional rest adjustment is in order. It’s a tweak you may want your pro to do. We’re taking 1/64 inch, most of the time, when adjusting rests after walk-back tuning.
Get Your Heads :
At this point, you should be able to set your target on an ant hill and use the insects crawling up its face for 30-yard field-point practice. But you’ll use broad heads in the deer woods–and that can introduce new problems. Having a well-tuned bow and perfect arrows will fix most problems people have with their broad heads. Whether fixed or mechanical but not every broad head, including from the same package, is always the same. If you’re striving for precision, it’s a good idea to weigh those broad heads after taking them from the package then put them on your arrows and spin-testing each.
Sight-In With Broad heads:
With a well-tuned bow matched with the right arrows, there should be little difference between the point of impact of your field points and your weighed and spin-tested broad heads. As a rule, broad heads, especially fixed-blade broad heads, are less forgiving to shoot. So it’s critical to do your broad head sight-in when you’re fresh. Don’t screw on your broad heads to see what happens after you’ve been shooting for an hour. A few bad releases or a lapse in form can give you false results. When that happens, it’s tempting to start moving your sight or rest around. Don’t do it. Sight in your broad heads over the course of a couple of days, making sure every shot you take is your best.
If you follow these steps, you’re probably not going to have many troubles for a year or more. Once a modern bow is in tune, it stays that way for a while. If there are issues, chances are it’s the user and not the equipment. But if you are having a problem, it can’t hurt to revisit each key component. Starting with your bow and accessories, and then moving on to your arrows and broad heads. Before you make any major tweaks, go visit your bow-shop pro. Odds are, it something simple that you’re overlooking. He’ll soon have you back in the woods and hitting where you aim.
