Adjusting the tiller on your recurve bow is crucial for achieving balanced performance and accurate shooting. By understanding the effects of too much, too little, and just right tiller settings, you can fine-tune your bow for the best results.

What is Tiller?

Tiller refers to the difference in distance between the upper and lower limbs of a recurve bow when the bow is strung. Proper tiller adjustment is crucial for achieving balanced shooting and consistent arrow flight.

Why is Tiller Important?

The tiller adjustment affects the bow’s balance, aiming, and overall performance. Correct tiller setting ensures that both limbs work in harmony, providing a smooth and accurate shot.

Steps to Adjust Tiller

1. Measure the Initial Tiller

  • Use a bow square or a ruler to measure the distance from the string to the base of the limb (where it meets the riser) for both the upper and lower limbs.
  • Note the measurements for both limbs.

2. Determine the Ideal Tiller Setting

  • For most recurve bows, a slight positive tiller (where the upper limb distance is slightly greater than the lower limb distance) is recommended.
  • The typical tiller difference is around 1/8 to 1/4 inch (3-6 mm).

3. Adjust the Tiller

  • Locate the tiller bolts or adjustment screws on the bow’s riser.
  • Increasing Upper Limb Tiller: To increase the tiller on the upper limb, tighten the tiller bolt or screw on the upper limb.
  • Decreasing Upper Limb Tiller: To decrease the tiller on the upper limb, loosen the tiller bolt or screw on the upper limb.
  • Adjust the lower limb tiller similarly, if necessary, to achieve the desired tiller difference.

The Impact of Tiller Adjustment

Too Much Tiller

  • Pros: May stabilize the bow for some archers; can help with aiming adjustments.
  • Cons: Can cause imbalance in limb synchronization; may result in inconsistent arrow flight.
  • Characteristics: The upper limb has a significantly greater distance from the string compared to the lower limb.

Too Little Tiller

  • Pros: May suit some shooting styles; can make the bow feel more balanced.
  • Cons: Can cause uneven stress on the limbs; may affect arrow flight negatively.
  • Characteristics: The upper limb distance from the string is very close to or the same as the lower limb distance.

Just Right Tiller

  • Pros: Provides optimal balance and limb synchronization; ensures consistent and accurate arrow flight.
  • Cons: Requires fine-tuning and testing.
  • Characteristics: The upper limb has a slightly greater distance from the string than the lower limb, typically around 1/8 to 1/4 inch.

Tips for Fine-Tuning

  • Test Shooting: After adjusting the tiller, shoot several arrows to assess the bow’s performance. Observe the balance, aiming stability, and arrow flight.
  • Make Small Adjustments: Adjust the tiller in small increments and retest. This helps to find the best setting for your shooting style.
  • Record Your Settings: Keep a record of the tiller settings that work best for you. This ensures consistency in future shooting sessions.
