Question 1

What is the primary purpose of a bow's control cables on a compound bow?

Accepted Answer

Synchronize cam rotation and control limb movement

Answer

Control cables synchronize the rotation of the cams and control limb deflection throughout the draw cycle, ensuring proper timing and cam alignment.

Question 2

Which material is most commonly used in modern high-performance bow strings?

Accepted Answer

Dyneema/SK75 or similar UHMWPE fibers

Answer

Ultra-High Molecular Weight Polyethylene (UHMWPE) fibers such as Dyneema SK75 offer very low stretch, high strength, and minimal creep, making them the dominant material in modern performance strings.

Question 3

What does 'string stretch' (creep) cause on a compound bow after initial break-in?

Accepted Answer

Loss of draw length and potential timing issues

Answer

As strings creep over time, their effective length increases, which shortens draw length and can throw cam timing off, negatively affecting bow performance.

Question 4

When twisting a bow string to adjust brace height, which direction of twist shortens the string?

Accepted Answer

The same direction as the string's original lay

Answer

Twisting a string in the same direction as its original lay (adding twists) shortens the string, which increases brace height.

Question 5

What is the ATA-recommended minimum brace height range for most compound bows?

Accepted Answer

6–8 inches

Answer

Most compound bows are engineered for a brace height between 6 and 8 inches, though the manufacturer's spec should always be the primary reference.
