How To Fix Cam Lean

Cam lean is one of the most discussed, debated and argued topics beyond archers when talking near bow tuning and its furnishings. There are many unlike approaches to addressing cam lean. Some choose to ignore it or pretend it does not exist, while some utilize it every bit a tuning tool. The reality is that it does exist in varying degrees on every compound bow and should be understood by anyone who wants to get a more 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, information technology would be like to the camber of the wheels. Imagine looking at the back of a car with four passengers inside, two on the driver'south side and two on the passenger side, and they all weigh well-nigh the same weight. One would await the machine'due south opinion to exist level and flat. Now what would happen if all the passengers motion to the right side of the car? The machine would now sit lower on the right side than the left. This is the aforementioned thing that happens when the string and cable tensions modify 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?

In that location are a number of factors that tin can contribute to, and/or generate cam lean. The primary reason cam lean exists it considering of the variation in loading on the axle throughout the draw cycle. When a bow is drawn the limbs are being flexed and building free energy, and every bit the describe weight climbs and falls into the let off, the tensions on the strings and cables modify. At full draw, the string has very trivial tension and the cables have their maximum amount, while a rested bow has little tension in the cables and a lot of tension in the strings. This modify in tension throughout the draw cycle will force the axle and cam to change its position relative to the bows vertical plane.

Other factors that can influence cam lean would exist the limb deflections from ane side of the cam to the other. If the cable side limb is stiffer than the cord side it can influence the lean of the cam (or vice versa). The position of the cam (left and correct) will likewise make up one's mind the lean of the cam. This goes back to the position of the weight or tension on the axle. On a right handed bow, moving the cam to the correct will cause the cam to lean away from the cables, and moving the cam to the left will cause the cam to lean towards the cables. Most modernistic bows utilise spacers to locate the position of the cams on the beam, which can exist adjusted to alter the lean of the bow.

What do I do about cam lean?

Cam lean should simply exist adapted past an authorized, trained technician. Shooting a bow with excessive cam lean could result is string derailment and potential injury.

As an archer, you should accept that your bow'due south cams will not exist perfectly straight at both brace and full draw. Cam lean can be used as a powerful tool to help get the nearly forgiving, well-tuned bow possible. Arrow flying tin exist affected by many dissimilar factors including grip position, face pressure on the string, arrow choice, rest position and blazon.

We volition unremarkably see that unlike grip styles volition have a different result on the flight of the arrow due to uneven force per unit area on both sides of the bow. Someone who applies more force per unit area on the thumb side of the grip will get a unlike newspaper or bare shaft tune then someone who uses less. For this reason, i archer may get a perfect bullet pigsty while another will get a right tear. Oft with more experienced archers who do not want to change their grip, adjusting the lean of the cam will help residue out the pressure level put on the bow by a specific grip.

The bow must really exist tuned to the individual archers shooting style. Personally, my bows will tune the best with an equal amount of static lean at brace as there is at total draw. This means that my cams are slightly leaning toward the cables at the brace summit position, and slightly leaning abroad from the cables at full draw. I am not concerned nigh the exact setting as long as I am getting the arrow flight I demand. I want to give the bow what it needs to exist the most forgiving setup possible.

For a right-handed shooter if y'all are fighting a left tear, and yous have exhausted other tuning techniques (rest position, cable position etc.), then moving your cams to the left slightly volition help clear up that tear. When making any cam position changes it is extremely important to start small and brand certain the cams are tracking properly in between every adjustment. Again we advise that adjusting cam spacing should just be done by a trained bow technician.

How does cam lean upshot shooting?

Cam lean should but be looked at as a "problem" when it is excessive and causing string tracking or wear issues. Determining what is considered "excessive" tin be difficult when information technology comes to cam lean. If yous tin experience the cablevision popping into the module groove, or the cord is non tracking into the string track groove, yous may have excessive cam lean. Shooting a bow with excessive cam lean could cause the string 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 remainder any torque you lot are putting into the bow from your grip pressure level of face pressure on the string. You may have noticed you can easily change the appearance of how the strings are tracking into the grooves by adjusting your grip on the bow. The angle of the cam volition aid offset the torque on the bow from the archer. This will bear witness up in your tuning methods (paper, blank shaft, broadhead etc.) every bit poor arrow flight.

Cam lean is a characteristic of the chemical compound bow that needs to be understood and utilized every bit a method of tuning. Nosotros transport every Elite bow with the cam lean set to a predetermined specification. This is the level we have found to exist the most forgiving to go a bow to tune easily. If your grip mode or other factors do not let the bow to tune with that setting, then make a small adjustment and become back to shooting. Some people choose to look at cam lean like it'southward a dingy word or information technology doesn't exist, but in reality, they are missing an important characteristic of the tuning of their bow.
