How does a compound bow cam work?

How does a compound bow cam work?

A compound bow works as a block and tackle system, relying on mechanical advantage to decrease the draw weight. By changing the distance from the axis, the cam and mod decrease the amount the limb is compressed per inch of draw length at the end of the draw.

What is cam lean on a compound bow?

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 camber of the wheels. Imagine looking at the back of a car with 4 passengers inside, two on the driver’s side and two on the passenger side, and they all weigh about the same weight.

Does adjusting draw weight affect cam timing?

Dropping draw weight WILL NOT change cam timing. Only thing it will change is draw length and draw weight.

How do you tune a single cam compound bow?

Super Tuning your Single-cam Bow shoot a bare shaft through paper until you get perfect bullet hole. Adjust cam lean until left/right tears are gone. For nock-left tear, add twists to right yolk. For nock-right tears, add twists to left yolk.

What are the parts of a compound bow string?

Parts of a bow string

• Bow string. The bow string attaches to the limbs of a longbow or recurve bow.
• String silencer. As the name implies, a string silencer reduces string noise and vibration through an elastic material added to the string.
• Kisser button.
• Serving.
• Nock locator.
• Release aid loop.

What does a stabilizer do on a compound bow?

Share: Stabilizers come in many sizes and configurations, but all serve the same purpose. They reduce vibration when the archer releases an arrow, and stabilize the bow by increasing its inertia. Without stabilizers, bows can feel unstablewhile archers aim, potentially making it difficult to hold their bow stationary.

What is the yoke on a compound bow?

Yoke tuning is the adjustment of control cable where it splits or becomes a “yoke” in order to achieve a flawless path of movement for the string. When properly yoke tuned, the bowstring will track off the idler wheel straight at full draw, without veering to the right or the left.

What are compound bow cams and how do they work?

Cams are the pulleys or wheels attached at the end of the limbs. Cams are what distinguish a compound bow from more traditional bow types. The further you draw a traditional recurve or longbow, the harder it gets to pull. When you pull the string back on a compound bow, the cams mechanically manipulate the draw weight.

What’s the point of a compound bow?

The compound bow fixes both of these fundamental problems, thanks to the magic in the those cams. The compound bow not only stores more energy by manipulating the forces, but it “lets-off” (partially relaxes) at the end of the drawstroke, so you’re holding less weight at full draw, allowing you more time at to aim and fire. Brilliant!

What is a binary cam bow?

A binary cam bow is said to provide equalization on bow strings, control cables and limbs via a system that coordinates the rotating of both cams at the same time, because they are “slaved” together. This process has been called “auto-correcting” or “equalizing” everything, giving the shooter a perfect arrow every time.

Are compound bows harder to draw?

The further you draw a traditional recurve or longbow, the harder it gets to pull. When you pull the string back on a compound bow, the cams mechanically manipulate the draw weight. Once you reach a certain point, it becomes noticeably easier to draw the bow as the cams do some of the work for you.
