Archery Basics Explained | Tiller

Introduction

This tutorial will guide you through understanding and adjusting the tiller of your bow, a crucial aspect that affects precision and comfort in archery. By mastering tiller adjustments, you can enhance your shooting experience and improve your performance.

Chapter 1: Understanding Tiller

• Definition: Tiller refers to the difference in length between the top and bottom limbs of the bow. This balance significantly influences how the bow feels at full draw.
• Importance: Different shooting styles require specific tiller setups:
  • Split Finger: One finger above and two below the arrow.
  • Three Under: All three fingers below the arrow.
  • String Walking: Adjusting finger positions along the string for barebow shooting.

Chapter 2: Measuring Tiller

To measure tiller, you will need a bow square (an L square or T square will work).

1. Position the Square: Place the square against the base of the limb where it meets the riser.
2. Measure: Extend the square at a 90-degree angle to the string.
   • Record the distance for the top limb (e.g., 7 1/16 inches).
   • Record the distance for the bottom limb (e.g., 6 15/16 inches).
3. Calculate the Difference: Subtract the bottom measurement from the top measurement to determine the tiller split (e.g., an eighth-inch shorter on the bottom).

Chapter 3: Adjusting Tiller

If your bow has adjustable limb bolts, follow these steps to modify the tiller:

1. Tools Needed: Use an Allen wrench to loosen the locking mechanism on the limb bolts.

2. Adjustments:

   • To tighten the top limb (shorten its measurement), turn the tiller bolt clockwise. This increases tension.
   • To loosen the top limb (lengthen its measurement), turn the tiller bolt counter-clockwise.
   • Remember, adjustments do not have to be equal on both limbs.

3. Unstringing the Bow: For significant adjustments, unstring your bow to preserve its longevity.

Chapter 4: Recommended Tiller Settings

• For Split Finger or Mediterranean Draw: Set the bottom tiller to be about 1/8 to 1/4 inch shorter than the top.
• For Three Under: Aim for equal tiller or have the bottom tiller slightly longer (up to 1/8 inch).
• For String Walking: The bottom tiller may need to be 1/8 to 1/4 inch longer than the top, depending on the draw position.

Chapter 5: Tracking Your Adjustments

• Keep a notebook to record each adjustment and its impact on performance.
• Note how the bow feels at full draw, allowing you to revert to previous settings if necessary.

Conclusion

Understanding and adjusting your bow's tiller can greatly enhance your shooting comfort and accuracy. Regular adjustments based on your shooting style can lead to tighter groups and improved scores. Experiment with different settings to find what works best for you, and don't hesitate to make adjustments as you refine your technique. Happy shooting!
