How to Adjust the Draw Weight on Compound Bow

Accuracy is key when shooting. The most important factor to consider is knowing how to adjust the draw weight on a compound bow. The ideal range for different shooters will vary depending on their technique, goals, and the type of arrow they use each stage to ensure maximum accuracy!

It’s very important to adjust the draw weight for the right direction and distance to use the bow with maximum efficiency. The process is not difficult, but it’s important to follow the steps carefully to avoid any mistakes. 

How to Adjust the Draw Weight on Compound Bow

5 Steps to adjust the draw weight on compound bow 

Here we will discuss a complete step-by-step guide on how to adjust the draw weight on a compound bow. 

So, without further ado, let’s get into it.

1- Loosen the locking screws

To adjust the draw weight on your compound bow, you must first loosen the locking screws. Once the screws are loosened, you can adjust the limb bolts to increase or decrease the tension on the bowstring. This will, in turn, adjust the draw weight. 

When adjusting the draw weight, it is important to make small increments so that you do not over-adjust and end up with a too-light or heavy bow to shoot comfortably. Once you have adjusted the draw weight to your liking, retighten the locking screws so that your adjustment remains.

Warning: Don’t forget to tighten the locking screw.

2- Adjust the draw weight of the upper limb

Adjusting the draw weight of a compound bow is a relatively simple process that can be done in just a few minutes. Once the screws are released, you can use a hex/Allen wrench to turn the tiller bolt clockwise or counterclockwise to increase or decrease the draw weight.

 Be sure to test the bow after making adjustments to ensure it is set to your desired level. Adjusting the draw weight is important to get the most out of your compound bow and can help you improve your accuracy and shooting performance.

Alert:  When decreasing the draw weight on your bow, always be cautious not to over-untwist the tiller bolt. If you screw too much, It can result in serious injury and damage to your bow.

3- Adjust the draw weight of the lower limb

Adjusting the draw weight of the lower limb is a simple step that anyone can do, regardless of experience level. First, you will need to identify the tiller bolts on the bow. These are typically located near the center of the bow and are used to adjust the tension on the limbs. 

Next, use a wrench to turn the bolts in the same direction. You will notice that the draw weight increases as you turn the bolts. Once you have reached the right draw weight, tighten the bolts to secure them.

Some archers prefer to use a method of marking tiller bolts to keep track of the number of turns. This can be done using a marker to set a stripe on both bolts. The markings are easily removed with a damp cloth once you have made adjustments.

4- Check the draw weight.

After adjusting the draw weight, check to see if it was done correctly by either using a bow scale or simply going off of feel. I suggest the generic brand model if you want an inexpensive yet dependable bow scale. I purchased it and have used it numerous times with successful results each time!

It is easy to measure the draw weight of a recurve bow with a luggage scale. But it is much more difficult to do so with a compound bow. Measuring the peak draw weight with an ordinary luggage scale is tricky. If you’re unsure how to measure the peak draw weight, my in-depth article will give you all the information you need.

The proper way to measure your draw weight
Adjust the upper limb again if you want to change the draw weight. Check your draw weight after every cycle, as it can increase/decrease rapidly with two full twists.
If you want to make smaller adjustments, use half-turns or quarter-turns. Just remember to apply the same number of turns to each limb.

5- Check the tiller height 

Check the tiller height on your compound bow and correct it if necessary. The tiller is the distance between the string and the bow’s grip. Check it by holding the bow horizontally before you and measuring the distance from the string to the top of the grip. It should be 1/8 to 1/4 inch (3.2 to 6.4 mm). 

If it’s not, loosen the limb bolts and adjust the limbs until the tiller is correct, then retighten the limb bolts. Check your owner’s manual for more specific instructions. While at it, check the draw weight and correct it if necessary. The draw weight is how much force you need to draw the bowstring back. Check it by attaching a scale to the string and pulling it back until the arrow is at full draw. 

The draw weight should be between 40 and 60 pounds (18 and 27 kg) for most adult shooters. If it’s too heavy or too light, you can adjust it by turning the limb bolts clockwise to increase the draw weight or counterclockwise to decrease it. Check your owner’s manual for more specific instructions.

Tips Before You Start Tuning Your Bow:

We want to give you the following tips to make the process easier and more enjoyable.

  1. Check your bow for damage. If you see any cracks or missing pieces, don’t tune your bow until you’ve repaired it.
  2. Don’t over-tighten the strings. This can cause the bow to break.
  3. Be careful when handling the bow. The string is under tension and can snap if handled roughly.
  4. If you’re unsure how to tune your bow, take it to a professional archer or bowyer for help.
  5. Tune your bow regularly. This will ensure that it performs at its best and lasts longer.
