How To Fix Cam Lean On A Bow

Cam lean is one of the most discussed, debated and argued topics across archers when talking virtually bow tuning and its effects. There are many different approaches to addressing cam lean. Some cull to ignore information technology or pretend information technology does not exist, while some apply it every bit a tuning tool. The reality is that it does be in varying degrees on every compound bow and should be understood by anyone who wants to get a more than precise shot.

What is cam lean?

Cam lean is the difference in angle from the plane of the cam to the vertical plane of the bow. In cars, it would be similar to the slant of the wheels. Imagine looking at the dorsum of a car with 4 passengers within, two on the driver's side and 2 on the passenger side, and they all counterbalance almost the same weight. Ane would wait the car's opinion to exist level and apartment. At present what would happen if all the passengers move to the right side of the car? The motorcar would now sit lower on the right side than the left. This is the same thing that happens when the cord and cable tensions change throughout the depict of the bow. When either the strings or cables are more compressed than their counterpart, the cam will lean. Some compound bows will have greater degrees of cam lean than others due to the different types of cam systems on today's bows.

Why does cam lean exist?

There are a number of factors that can contribute to, and/or generate cam lean. The primary reason cam lean exists it because of the variation in loading on the beam throughout the draw bicycle. When a bow is drawn the limbs are being flexed and building energy, and as the describe weight climbs and falls into the allow off, the tensions on the strings and cables change. At full draw, the string has very little tension and the cables accept their maximum amount, while a rested bow has little tension in the cables and a lot of tension in the strings. This change in tension throughout the describe bicycle will force the axle and cam to change its position relative to the bows vertical plane.

Other factors that can influence cam lean would be the limb deflections from one side of the cam to the other. If the cablevision side limb is stiffer than the string side it can influence the lean of the cam (or vice versa). The position of the cam (left and right) will likewise determine the lean of the cam. This goes dorsum to the position of the weight or tension on the axle. On a right handed bow, moving the cam to the right will cause the cam to lean away from the cables, and moving the cam to the left will crusade the cam to lean towards the cables. About mod bows use spacers to locate the position of the cams on the axle, which can exist adapted to modify the lean of the bow.

What exercise I do about cam lean?

Cam lean should only be adjusted by an authorized, trained technician. Shooting a bow with excessive cam lean could result is string derailment and potential injury.

Equally an archer, you should accept that your bow's cams volition not be perfectly directly at both caryatid and full draw. Cam lean tin can be used as a powerful tool to assistance become the most forgiving, well-tuned bow possible. Arrow flight tin can be afflicted by many dissimilar factors including grip position, face pressure on the string, arrow choice, residuum position and blazon.

We will commonly see that dissimilar grip styles will accept a different effect on the flight of the arrow due to uneven pressure on both sides of the bow. Someone who applies more than force per unit area on the pollex side of the grip will get a unlike newspaper or bare shaft melody so someone who uses less. For this reason, one archer may get a perfect bullet hole while some other will get a right tear. Often with more than experienced archers who do not desire to alter their grip, adjusting the lean of the cam will assistance balance out the pressure level put on the bow by a specific grip.

The bow must actually be tuned to the private archers shooting style. Personally, my bows will melody the best with an equal amount of static lean at brace equally there is at full draw. This means that my cams are slightly leaning toward the cables at the brace height position, and slightly leaning away from the cables at total describe. I am not concerned nearly the verbal setting as long equally I am getting the arrow flight I need. I want to requite the bow what information technology needs to exist the nearly forgiving setup possible.

For a correct-handed shooter if yous are fighting a left tear, and you accept exhausted other tuning techniques (residue position, cable position etc.), then moving your cams to the left slightly will help clear upwardly that tear. When making any cam position changes it is extremely important to start small and make sure the cams are tracking properly in betwixt every adjustment. Again we advise that adjusting cam spacing should only exist done by a trained bow technician.

How does cam lean effect shooting?

Cam lean should merely be looked at as a "problem" when it is excessive and causing string tracking or wear issues. Determining what is considered "excessive" can be difficult when information technology comes to cam lean. If you can feel the cable popping into the module groove, or the cord is not tracking into the string runway groove, you may have excessive cam lean. Shooting a bow with excessive cam lean could cause the cord to derail on the shot and pose a danger to the archer.

The position of your cams needs to be set to the position that helps residue any torque y'all are putting into the bow from your grip pressure of face pressure on the string. You may have noticed y'all tin hands change the appearance of how the strings are tracking into the grooves by adjusting your grip on the bow. The bending of the cam will help offset the torque on the bow from the archer. This will testify up in your tuning methods (paper, blank shaft, broadhead etc.) as poor pointer flight.

Cam lean is a feature of the compound bow that needs to exist understood and utilized as a method of tuning. We ship every Elite bow with the cam lean set to a predetermined specification. This is the level we take found to be the nearly forgiving to become a bow to tune easily. If your grip style or other factors do not allow the bow to tune with that setting, then brand a pocket-size adjustment and go back to shooting. Some people choose to look at cam lean like information technology's a dingy word or it doesn't be, but in reality, they are missing an important characteristic of the tuning of their bow.
