What is Cam Timing?
Cam timing in a compound bow refers to the synchronization of the cams, which are the oval or circular devices at each end of the bow that help transfer energy to the arrow. In simple terms, properly timed cams ensure that the cables and the string move in harmony, leading to a more efficient and accurate shot.
Why Cam Timing is Crucial
Cam timing directly impacts the performance of your bow. Misaligned cams can result in variances in arrow speed, inconsistent accuracy, excessive vibration, and even undue stress on your bow limbs. Achieving perfect cam timing means your bow will perform more efficiently, providing smoother shots and reducing the risk of component wear and tear.
How to Check Your Cam Timing
Before you start adjusting, you need to know how to check your cam timing. Here’s a step-by-step guide to get you started.
Tools You’ll Need
- Allen wrenches
- Bow press (if necessary)
- Bow scale
- Measuring tape or ruler
Basic Steps to Check Cam Timing
-
Draw the Bow:
Pull back the string until you reach full draw, either using a draw board or having someone assist you carefully. -
Observe Cam Movement:
Look at when each cam stops rotating. Ideally, both cams should stop at the same time. -
Measuring Points:
Identify buffer stops or timing marks on the cams. Most bows have these indicators. -
Measure and Compare:
Use your measuring tape to check if the draw stops on both cams are contacting the string at the same time.
If you notice any discrepancy in the timings, it’s time to make some adjustments.
How to Adjust Cam Timing
Understanding the Basics
Adjusting cam timing involves either advancing or retarding one or both cams to ensure they hit their stops simultaneously at full draw. Here are some common ways to adjust cam timing.
Use a Bow Press Responsibly
Using a bow press is often necessary for adjusting cam timing, but it’s also a tool that should be handled with caution. It relieves the tension from the bow strings and cables, allowing you to make necessary adjustments.
-
Prepare Your Bow Press:
Follow the manufacturer’s instructions to set up your specific bow in the press. -
Relieve Tension:
Gradually crank the press to relieve tension. -
Adjust Cam Timing:
Now that the tension is off, you can twist or untwist the cables and buss cables to achieve the desired cam rotation.
Twisting and Untwisting Cables
- Twisting: Shortening the cable by adding twists will advance the cam.
- Untwisting: Lengthening the cable by removing twists will retard the cam.
Re-assess Timing
Once you’ve made your adjustments, recheck the cam timing by drawing the bow again and observing the cams’ movements. Repeat this process until the cams are synchronized.
Effects of Poor Cam Timing
Understanding the repercussions of poor cam timing is essential. Misaligned cams can lead to a variety of performance issues:
| Problem | Symptom |
|---|---|
| Reduced Accuracy | Inconsistent grouping |
| Increased Vibration | More felt recoil |
| Uneven Wear | Additional stress on bow limbs |
| Speed Variance | Fluctuating arrow velocities |
Tuning Your Compound Bow: Step-by-Step
Fine-tuning your compound bow might sound daunting, but it’s actually a systematic process. Here’s a comprehensive guide to help you out.
Step 1: Set Your Draw Length
Your draw length should be set according to your physical dimensions. An incorrect draw length can make tuning impossible, so it’s crucial to get this right first.
Step 2: Adjust Your Draw Weight
Draw weight refers to the amount of force required to draw the bowstring. Make sure this is within your comfort level and doesn’t strain you.
Step 3: Cam Adjustment
Using the methods discussed above, ensure that both cams are synchronized.
Step 4: Paper Tuning
Paper tuning involves shooting the arrow through a piece of paper to observe how it tears. This helps you identify what needs to be adjusted.
Step 5: Walk-Back Tuning
Walk-back tuning is a method where you shoot arrows at incrementally increasing distances to determine if your sight is adjusted correctly and to fine-tune your bow further.
Step 6: Broadhead Tuning
After completing the above steps, it’s time to use your hunting arrows with broadheads to ensure they fly true.
Common Cam Systems and Their Adjustments
Understanding different cam systems is important as each has its unique set of adjustments and considerations. Here are the most common types:
Single Cam
Single cam bows are simpler because they feature one cam and one idler wheel. They are easier to tune and maintain.
Twin Cam
Twin cam bows (also called two-cam bows) have two matching cams. They require regular checking and are a bit trickier to synchronize.
Hybrid Cam
Hybrid cam systems come with a control cam and a power cam. They offer less timing and synchronization issues compared to twin cams.
Binary Cam
Binary cams are essentially two interlinked cams that work in unison. The system eliminates most timing issues but requires fine-tuning.
FAQs About Cam Timing
How Often Should You Check Cam Timing?
Regular checks are necessary to maintain peak performance. Ideally, you should check the cam timing every time you restring your bow or notice performance issues.
Can You Adjust Cam Timing Without a Bow Press?
While minor adjustments can sometimes be made without a bow press, most significant changes require one.
Is Cam Timing the Same as Tuning?
People often confuse cam timing with general bow tuning. Remember, cam timing is just one aspect of the tuning process.
Tips for Maintaining Cam Timing
Regular Inspections
Check your cams, strings, and cables regularly for wear and tear.
Proper Storage
Store your bow in a cool, dry place to avoid material degradation.
Use Quality Components
Investing in high-quality strings, cables, and cams can make a significant difference in maintaining proper cam timing.
Seek Professional Help
If you’re unsure or new to bow tuning, seeking help from a professional can be immensely helpful. Archery shops often provide tuning services, and they can guide you through the intricacies of cam timing.
Conclusion
Tuning your compound bow’s cam timing might seem complicated at first, but it’s essential for optimal performance. By understanding and adjusting cam timing, you can significantly improve your shot consistency, accuracy, and overall archery experience. So, grab your tools, use this guide as a reference, and get to work on fine-tuning your bow. Happy shooting!
