When aiming to establish the appropriate draw weight for your compound bow, it’s crucial to consider your strength, bow specifications, and intended use. The draw weight, measured in pounds, represents the force required to pull the bowstring back to the ideal anchor point. Determining the optimum draw weight for your bow is fundamental in ensuring accuracy, comfort, and effective performance
To commence, it’s advisable to consult the manufacturer’s recommended guidelines for your specific bow model. These recommendations provide a starting point and help you avoid exceeding the bow’s safe operating range. Next, stand with your feet shoulder-width apart and hold the bow vertically in front of you. Grasp the bow grip firmly with your dominant hand and place your fingers in the designated finger holes on the bowstring
Begin drawing the string back smoothly and steadily, maintaining a 90-degree angle at your elbow. As you draw the string back, notice the increasing tension and resistance. When you reach a point where it becomes noticeably challenging to continue the draw, that’s an indication that you have reached your maximum effective draw weight. It’s essential to avoid overexerting yourself, as this can compromise your form and accuracy
Identifying the Draw Weight System
Determining the Draw Weight Range
The draw weight system on a compound bow determines the amount of force required to pull back the string. This force is typically measured in pounds. Most compound bows have a draw weight range, which is the minimum and maximum amount of weight that can be set. The range is typically marked on the cam or riser of the bow. For example, a bow with a draw weight range of 50-70 pounds can be set to any weight within that range.
To determine the draw weight range of a particular bow, consult the manufacturer’s specifications. You can also look for the draw weight range marked on the bow itself. If you cannot find the draw weight range, you can estimate it by using a bow scale, which is a device that measures the force required to pull back the string.
Locating the Adjustment Bolts
To adjust the draw weight on a compound bow, you need to locate the adjustment bolts. These bolts are typically located on the bow’s cam or limbs. The adjustment bolts may be marked with a plus (+) or minus (-) sign, indicating the direction in which you turn the bolt to increase or decrease the draw weight.
If you cannot find the adjustment bolts, consult the manufacturer’s instructions for your bow. You can also look for videos or online tutorials that show how to adjust the draw weight on a compound bow.
Estimating the Draw Weight
Once you have located the adjustment bolts, you can estimate the draw weight by turning the bolts in or out. As you turn the bolt in, the draw weight will increase. As you turn the bolt out, the draw weight will decrease.
To estimate the draw weight, start by setting the adjustment bolts to the middle of their range. Then, use a bow scale to measure the draw weight. Adjust the bolts until you reach the desired draw weight.
Measuring Your Draw Length
Determining your draw length is crucial for achieving optimal accuracy and comfort when shooting. Here’s a step-by-step guide:
- Stand upright with your feet shoulder-width apart.
- Reach forward with your dominant arm and extend your fingers as if drawing an arrow.
Fingertip to Crease Draw Length (in inches) Base of your thumb 26-27 Corner of your mouth 27-28 Side of your nose 28-29 - Measure the distance between your fingertips and the crease formed by your bowstring hand’s thumb and forefinger using a measuring tape or arrow shaft.
- Round up or down to the nearest inch to determine your draw length.
Tips:
- Repeat the measurement several times to ensure accuracy.
- Consider your shooting style and personal preferences when choosing a draw length.
- A slightly shorter draw length can enhance accuracy, while a longer draw length may provide more power.
Setting the Axle to Cam Distance
The axle-to-cam (A2C) distance is measured from the center of the bow’s axle to the center of the cam. This distance affects the bow’s draw weight, draw length, and overall performance. To set the A2C distance, follow these steps:
Step 1: Determine the Correct A2C Distance
Refer to your bow’s user manual or consult with a professional archery technician to determine the appropriate A2C distance for your draw length and shooting style. Different bows have different A2C distance ranges, so it’s important to get it right for your specific setup.
Step 2: Adjust the Bow Press
Place your bow in a bow press and adjust the press to slightly compress the limbs. Ensure that the bow is centered and secure in the press before proceeding.
Step 3: Measure the A2C Distance
Using a caliper or A2C measuring tool, carefully measure the distance from the center of the bow’s axle (the hole where the arrow passes through) to the center of the cam (the rotating wheel that drives the bowstrings). Compare this measurement to the desired A2C distance you determined in Step 1.
| A2C Distance | Draw Weight Increase |
|---|---|
| Increase A2C | Decrease Draw Weight |
| Decrease A2C | Increase Draw Weight |
Step 4: Adjust the Cam Position
If the measured A2C distance does not match the desired distance, you will need to adjust the cam position.
| Cam Rotation | Effect on A2C |
|---|---|
| Clockwise | Increase A2C |
| Counterclockwise | Decrease A2C |
Loosen the cam bolts on the bow and rotate the cam until the measured A2C distance matches the desired distance. Tighten the cam bolts securely when the correct A2C distance is achieved.
Once the A2C distance is set, you have completed one of the crucial steps in tuning your compound bow. Follow the remaining steps in the complete article to fine-tune your bow for optimal performance.
Adjusting the Limbs
The limbs of a compound bow are responsible for providing the power that propels the arrow. The draw weight of a bow is determined by the strength of the limbs, and it is important to adjust the limbs to the correct draw weight for your strength and shooting style.
Determining Your Draw Weight
The first step in adjusting the limbs is to determine your draw weight. This can be done by using a draw weight scale, which is available at most archery shops. To use a draw weight scale, simply attach it to the string of the bow, and pull back on the string until the scale reaches the desired draw weight.
Adjusting the Limbs
Once you have determined your draw weight, you can adjust the limbs to the correct setting. To do this, you will need to use a bow press, which is a tool that is used to compress the limbs of the bow. Here are the steps on how to adjust the limbs using a bow press:
- Place the bow in the bow press and secure it tightly.
- Locate the bolts that hold the limbs in place.
- Loosen the bolts on both limbs evenly.
- Adjust the limbs to the desired draw weight, using the scale as a reference.
- Tighten the bolts on both limbs evenly
- Remove the bow from the bow press.
Once you have adjusted the limbs to the correct draw weight, you should recheck the draw weight using the draw weight scale. This will ensure that the limbs are set to the correct tension.
If you are unsure about how to adjust the limbs on your compound bow, it is best to consult with a qualified archery professional for assistance.
Fine-Tuning with Draw Weight Adjustment Screws
Compound bows often have draw weight adjustment screws located on the limbs or cam modules. These screws allow for precise adjustments to the draw weight in small increments, typically ranging from 5 to 15 pounds.
To fine-tune the draw weight:
- Identify the draw weight adjustment screws on your bow. They are usually marked with an “A” or “B” and have a small hex head.
- Use a hex wrench or Allen key that fits the screw size. Turn the screw clockwise to increase the draw weight and counterclockwise to decrease it.
- Make small adjustments, typically in 1-pound increments. Turn the screw only a quarter to half turn at a time.
- Check the draw weight after each adjustment using a bow scale or by measuring the draw length and using a draw weight calculator.
- Repeat steps 2-4 until the desired draw weight is achieved.
| Adjustment Type | Effect on Draw Weight |
|---|---|
| Turn screw clockwise | Increases draw weight |
| Turn screw counterclockwise | Decreases draw weight |
Note: Make sure to adjust both limbs equally to maintain proper bow balance and avoid cam lean.
Ensuring Proper Bow Alignment
Adjusting the draw weight of a compound bow requires precise alignment between the bow limbs and the cams. This alignment ensures optimal performance and prevents premature wear and tear. Here are the steps to ensure proper bow alignment:
- Unstring the Bow: Before making any adjustments, unstring the bow to prevent damage or injury.
- Center the Bow: Place the bow in a bow stand or rest. Measure the distance from the nocking point to the center of each limb. Adjust the bow accordingly until it is perfectly centered.
- Align the Cams: Rotate the cams until they are centered and aligned with each other. Check if the cables are parallel and at equal tension.
- Set the Desired Draw Weight: Use an Allen key or wrench to adjust the limb bolts until you reach the desired draw weight. Turn the bolts clockwise to increase draw weight and counterclockwise to decrease it.
- Check Limb Synchronization: After adjusting the draw weight, check if the limbs are in sync. Grip the limbs firmly and pull the bow to full draw. Both limbs should move in unison.
- Fine-Tune the Alignment: Use a bow square or laser level to ensure the bow is square and aligned. Place the square or level on the limbs and adjust until the bubbles are centered. If necessary, make minor adjustments to the cams or limb bolts to achieve perfect alignment.
The following table summarizes the steps for ensuring proper bow alignment:
