A compound bow has three strings for two main reasons: (1) speed and power; and (2) ease to hold.
You also have to understand that the bow only has one bowstring and the other strings are cables that help improve the bow’s performance.
- More speed and power
- Easier to hold at the full draw
Compound bows have pulleys or cams attached near the riser. They are offset, so the arrow speeds up as it travels towards the target.
Additionally, with the correct weight, it will store more energy when fully drawn than a recurve or longbow that has equivalent draw weight. When released, you are transferring the stored energy to the arrow. You can do this by letting some of it go into the archery arrow on the downstroke.
By slowing down the arrow progressively through these two pulleys, more energy is placed into the archery arrow at the point of release, making for a faster and flatter shooting bow with more power than recurves or longbows.
The second reason for having three strings is that it helps hold the bow at full draw. When you draw a compound bow back, the string on the far side of the bow will get more pressure than the other two strings.
This action can significantly stress some bows, especially the older designs with more primitive cams. Keeping three strings makes this problem less severe because it spreads the load across them.
What are the parts of a compound bow?
There are four main parts to a compound bow: the riser, the limbs, the cam system, and the accessories.
- The riser is one of the parts of the bow attached to the limbs.
- The limbs are the flexible bow sections drawn back and pushed forward to fire an arrow.
- The cam system consists of pulleys attached to the riser and limbs that transfer force from arm brace to string to limbs. The cam system is one of the most critical parts of a compound bow, as it is responsible for transferring energy from the limbs to the arrow.
- Accessories are various options on a compound bow that you can purchase, such as sights, quivers, bowstrings, and cables.
- Buss cables
The bowstring is the string that transfers energy from the limbs into propulsion for an arrow.
There are two parts to a bowstring: a serving and a loop. The serving is the part of the bowstring that attaches to both ends, whereas a string loop is where you connect your arrows.
It can come in many sizes, but the most common length is 0.032 inches.
Buss cables are the cables that connect the cams on a compound bow. They are responsible for transferring energy from the cams to the limbs, and they also keep the cams in sync with each other.
What are the cables for on a compound bow?
The primary purpose of the cables is to provide stability and tension to the bow.
Compound bows usually have 2-4 cables running parallel to form a solid frame, but sometimes there are more or fewer cables depending on the model.
You can adjust the cable to ensure that they are tight and fit well. If the bow cables are too loose, it can affect the shooting performance.
If you have worn-out cables, you need to replace them with new ones right away. However, replacing the strings can be a bit tricky, so it’s best to leave it to the professionals if you’re not sure how to do it.
The cables on a compound bow play an essential role.
Here are a few of them:
- Easily transfer energy
- To easily hit the target
- To keep the bow in shape
- To increase your accuracy
- To keep everything in place
- To reduce the overall weight of the compound bow
The cables on a compound bow are responsible for transferring the energy from the bowstring to the limbs. This energy propels the arrow forward and lets you take down a small game.
Without the cables, the energy would be transferred directly from the bowstring to the arrow. This action makes it very hard for you to aim your shot. So, without cables, hitting even a stationary target would be difficult.
Drawing the bowstring back puts a lot of tension on the limbs and bow cables. This tension can cause the archery bow to deform over time if not correctly managed. So, these strings also help to maintain the shape of the bow.
Cables are responsible for pulling back the string while you aim. This pulling mechanism increases the accuracy of your shot. Additionally, it is easier to hold the bowstring back when the cables are doing all the work for you.
The limbs and the bowstring are attached to the cables. Which means that they will stay in place while you’re aiming and shooting. There is no risk of the limbs slipping off or the bowstring sliding down.
The cables are made out of lightweight materials so that they don’t add to the total weight of the bow, making it harder to handle and aim correctly.
Since cables are one of the mechanical parts in your compound bow, they have to be repaired from time to time. When you take good care of them more, you have to fix them less often. You can also increase their lifespan, which will allow you to save money in the long term.
Which cable is the control cable on a bow?
When looking at a bow, the control cable is on the bottom. You can use this cable to draw the bow and release the arrow.
This cable must be in good condition, as it can affect your accuracy. If the control cable is damaged or worn out, you may have difficulty drawing the bow and releasing the arrow.
Cables are the most critical part of a compound bow because they enable the archer to control and improve their aim. It contains many different motions depending upon its position with other bow components.
Additionally, it allows for longitudinal movement of the limbs and therefore controls the bow’s draw weight, making it critical. It is also composed of two-wire strands twisted around one another to form a more significant strand woven with fiberglass to add strength and durability.
When making adjustments to your bow, you have to be mindful to avoid inadvertently affecting the draw weight. Also, always make sure that your cables are correctly tensioned and lubricated to move smoothly and unnecessary strain on other components.
How many twists should a compound bow string have?
A compound bow string has two sets of twists. The first set is in opposite directions so that when one side stretches, the other compresses, and vice versa. The second set helps to maintain the tension in the string after release.
To determine how many twists a compound bow should have, you must consider its draw weight, draw length, cam-system, and string material.
The basic rule is that a lower draw weight requires a higher number of twists, and a longer draw length requires a lower number of twists.
- A 50lb draw weight with a 32 in. draw length would have approximately six twists in the top loop and four twists in the bottom.
- With a 40lb draw weight of 28in draw length, you would want eight and five twists, respectively.
The number of twists you need for your bowstring also depends on the type of cam system.
There are three types of cams: one-cam, twin-cam, and hybrid.
- One-cam systems have a single cam placed on the top half of the bow’s limbs. They are most common in youth bows. These bows require more twists in their string because you want them to be shorter, so they don’t hit your arm when shooting.
- A twin-cam system has two cams, one on each side of the bow. These bows are more accurate and longer draw length than a one-cam bow. They also require fewer twists in the string.
- Hybrid systems are a combination of one-cam and twin-cam systems.
The number of twists you need in your string will also vary depending on the string’s material. For example, nylon strings need more twists than Dacron strings because they are less elastic.
How often should you replace cables on a compound bow?
Generally, you can replace them every so often to ensure optimal performance. Typically, you can replace cables every 500-1,000 shot, but this may vary depending on the type of cables and the shooting habits of the archer.
If you notice that your cables are not performing as well as they used to or signs of wear and tear are showing, it is time to replace them. You can also replace the cables if you have trouble drawing the bow back.
It would be ideal that you have backup cables on hand just in case you need them.
When replacing cables, be sure to use the correct one for your bow. Many different types and sizes are available, so it is essential to find the right ones that fit.
It is also crucial to use quality cables, as low-quality cables may not last as long, may break on you while shooting, or they may not shoot as smoothly.
Replacing the cables is also part of your need to maintain your bow. Additionally, you have to make sure that you regularly wax the strings and cables. Wax helps protect them from dirt and moisture while you are practicing.
If you notice that the light coming through the peep sight is a bit dimmer than usual, it’s probably because dirt and debris have built up on your strings and cables, so make sure to clean them and apply some wax.
In addition to replacing cables when necessary, you should check for any loose screws on your bow. Loose screws can not only cause your bow to malfunction, but they can also be dangerous if the screw falls out while you are shooting.

What is Dacron string?
A Dacron string in a compound bow is a high-quality archery string made from a unique material called polyester or polyethylene terephthalate.
These types of materials both have the property of withstanding a fair amount of tension and compression, which makes them ideal for use as bowstrings. It is also similar to the one used in tennis racquets and other sporting equipment.
Dacron strings are available in both solid and stranded varieties.
- A solid Dacron string is a single, thick strand of the material, while a stranded Dacron string comprises several smaller strands braided together.
- The benefit of using a stranded string is that it is a little more flexible and can stretch a small amount.
- On the other hand, a solid Dacron string has a much smaller shock absorptions capacity due to its rigidity.
Dacron strings are often outfitted with a special kind of nock that allows the bowstring to fit onto the arrow rest easily and then be drawn back without getting hung up on the nock.
If you’re using solid Dacron strings, be sure to get the appropriate number of twists per inch for your bowstring. For stranded Dacron strings, there is no need to worry about this since the strands are already twisted together.
As a general rule, the Dacron string must have more twists per inch as it makes them perform better.
When shopping for a Dacron string for your compound bow, it is vital to ensure that you get the right size and type of string for your specific bow. In addition, different archery bows require different kinds of bowstrings, so be sure to do your research before purchasing.
If you’re looking to keep your Dacron strings in tip-top shape and prolong their shelf life, be sure to clean and wax them after every use. Waxing can help reduce wear and tear and allow the string to remain flexible.
Additionally, if you plan on storing your strings for an extended period, be sure to wax them before you put them away so that they won’t become dry and brittle while in storage.
