Mastering the art of archery requires precision and technique, and stringing a compound bow is a crucial step that demands attention to detail. Whether you’re a seasoned archer or just starting your journey, knowing how to string your bow correctly is essential for ensuring accuracy, performance, and safety. This comprehensive guide will walk you through the process step-by-step, providing clear instructions and helpful tips to help you achieve optimal bowstringing.
Before embarking on the stringing process, it’s important to gather the necessary tools. You’ll need a bowstringer, which is a device that helps you apply tension to the bowstring, as well as a bow square to ensure proper alignment. Additionally, a pair of gloves will protect your hands from potential abrasions. Once you have everything you need, find a safe and stable location where you can work without distractions.
Now, let’s begin the stringing process. Position your bow on the bowstringer, making sure that the limbs are parallel and the string groove is facing up. Take the bowstring and locate the center serving, which is the thicker, reinforced part of the string. Place one end of the center serving over the top cam, ensuring that it is seated properly in the groove. Then, carefully guide the other end of the bowstring over the bottom cam, again making sure it is seated correctly.
Tying the Serving Thread to the Nocking Point
To ensure a secure connection, it’s crucial to properly tie the serving thread to the nocking point. Follow these steps:
1. Locate the Nocking Point
Identify the nocking point on the bowstring. It’s typically a raised bump or a small metal loop located above the arrow rest. This point denotes the center of the bowstring, where the arrow will be nocked.
2. Prepare the Serving Thread
Cut a length of serving thread that is approximately twice the width of the nocking point. Unravel the ends of the thread and slightly fray them to create a “fuzzy” surface that will enhance adhesion.
3. Tying the Thread
Start by making an overhand knot at the end of the thread. Position the knot at the nocking point and slide it towards the center of the bowstring. Wrap the serving thread around the bowstring in a series of tight figure-eight loops, starting from the outside in and working your way towards the center. Each loop should overlap the previous one by about 50%. The number of wraps needed will vary depending on the thickness of the serving thread and the diameter of the bowstring. As a general guideline, aim for at least 10-15 wraps.
Once you have completed the required number of wraps, secure the thread by passing the free end through the loop created by the last wrap. Pull the end tightly to cinch the knot, then trim any excess thread.

Guiding the String Through the Cams
Threading the string through the cams is crucial for proper bow setup. Follow these detailed steps:
1. Position the Top Cam
Locate the top cam and rotate it until the arrow-shaped indicator on the cam aligns with the corresponding mark on the bow riser.
2. Thread the String into the Top Cam
With the string in hand, loop it around the opposite cam and pull it through the top cam’s groove. Ensure the string sits correctly in the groove, preventing any twisting or bundling.
3. Position the Bottom Cam
Rotate the bottom cam until its corresponding indicator aligns with the mark on the riser. This helps ensure proper timing between the top and bottom cams.
4. Thread the String into the Bottom Cam
Similar to Step 2, loop the string around the top cam and pull it through the bottom cam. Check for proper alignment and prevent twisting or bundling.
5. Check for Equal Tension on Both Limbs
Verify that the string tension is evenly distributed on both limbs. Use a bow square or other measuring device to ensure the distance from the nocking point to the string grooves on both cams is equal. This step is essential for balanced performance.
| Cam | Indicator Alignment |
|---|---|
| Top | Arrow indicator aligned with riser mark |
| Bottom | Indicator aligned with riser mark |
Attaching the String to the Upper Cam
The next step is to attach the string to the upper cam. This can be done by following these steps:
- Identify the serving point on the string. This is usually a small mark or knot in the middle of the string.
- Align the serving point with the upper cam groove. The groove is usually located on the top of the cam.
- Tie a small loop in the end of the string. This loop will be used to attach the string to the cam.
- Pass the loop over the cam groove.
- Tighten the loop until it is snug against the cam.
- Backtrack the string around the nearest cam lobe. This will help to secure the string in place. To do so:
- Pull the string back over the inside of the cam and slightly past the cam groove.
- Pull the string back towards the top of the cam, securing it in the groove where the string was originally placed.
- Wrap the string over the top of the cam and under the cam groove.
- Pull the string through the gap between the cam and the limb, under the cam, and slightly past the cam groove again.
- Pull the string back over the outside of the cam and secure it.
- Repeat steps 1-6 for the other end of the string.
Adjusting the Rotation of the Cams
Once the bowstring has been attached to the bow cams, it’s time to adjust the cam rotation. This crucial step ensures that the string is properly aligned with the cams, allowing the bow to function correctly.
To adjust the cam rotation, follow these steps:
1. Identify the Adjustment Screws
Locate the two small screws situated on the sides of the bow cams. These screws are usually marked with “+” or “-” signs.
2. Loosen the Screws
Using a T-handle Allen wrench, gently loosen both screws by turning them counterclockwise.
3. Determine the Direction of Rotation
Check the bow’s manual to ascertain the desired direction of rotation for the cams. This information may be specified based on the bow model or draw length.
4. Rotate the Cams
