What is Draw Weight?
Draw weight is an important element of archery that affects the speed, range and accuracy of the arrow. It is the amount of force that is needed to draw the bowstring back to its full draw length. The draw weight of a bow is usually measured in pounds and can vary from 10 pounds for a beginner’s bow to as much as 80 pounds for a professional’s bow. When a bow is drawn, kinetic energy is stored in the bow limbs, and the draw weight is the amount of energy that is required to draw the bowstring back to its full draw length.
Why Adjust Draw Weight?
Draw weight is an important factor to consider when choosing a bow and when tuning a bow. If the draw weight is too high, the bow may be difficult to draw and may not be comfortable to shoot, resulting in poor accuracy and form. If the draw weight is too low, the arrow may not have enough energy to reach its target. Adjusting draw weight can also be important for tuning a bow to shoot different types of arrows or to adjust the arrow’s trajectory.
How to Adjust Draw Weight?
The draw weight of a bow can be adjusted by replacing the bow limbs with heavier or lighter limbs. This is usually done by a professional archery technician. The technician will usually start by measuring the current draw weight of the bow and then replacing the limbs with heavier or lighter limbs until the desired draw weight is achieved.
Replacing the Bow Limbs
Replacing the bow limbs is a relatively simple process that can be done by a professional archery technician. The technician will first loosen the limb bolts and then remove the old limbs. The technician will then install the new limbs and torque the limb bolts to the manufacturer’s specifications.
Testing the New Draw Weight
Once the new limbs are installed, the technician will test the new draw weight by drawing the bow and measuring the draw weight with a draw weight scale. The technician will make any necessary adjustments to the limbs until the desired draw weight is achieved.
Adjusting the Tiller
After the desired draw weight is achieved, the technician will then adjust the tiller of the bow. The tiller of a bow is the difference in the distance between the string and the limb tips when the bow is drawn. The technician will measure the distance between the string and the limb tips and adjust the tiller until the desired distance is achieved. This will ensure that the bow is properly tuned and will shoot accurately.
Conclusion
Adjusting draw weight is an important part of archery and is necessary to ensure that a bow is shooting accurately and comfortably. It is important to have a professional archery technician adjust the draw weight of a bow to ensure that it is properly tuned and that it is comfortable and accurate. With the right draw weight, an archer can be sure that their arrows will be flying true.
