There are a handful of bow string materials on the market today that work very well when it comes to producing a custom bow string that will be durable and stable while providing good arrow speed. These materials would include D97, G, trophy, , X and X. BCY X has been around forever. It has proven itself time and time again. It is available in solid and speckled colors which is very nice for giving virtually unlimited color options for your custom bow string.
The one drawback to X is that it is prone to fuzzing. This was addressed when BCY introduced the trophy material. BCY is another material that has been around for quite a while. Due to its makeup it is more prone to stretch in the heat. Proof against moisture, more forgiving of large temperature swings, and more durable in the case of Dacron. However some of these also had serious disadvantages, compared to modern Spectra or Dyneema based string materials. Dacron will continually stretch and change over time, while Kevlar will always, eventually, unexpectedly break, seemingly often in the course of a competition.
There are some small differences between the two materials, and in particular, exactly how the fibers are spun, but they are, for the most part, identical. Practically impervious to many solvents, normal environmental conditions and moisture, the weak point with these materials comes into play at elevated temperatures typically beyond what one can expect to encounter in the course of a competition. The blend helped arrest creep, a permanent stretching condition common on compound riggings made with Dacron or UHMPE cables, until the gradual and inevitable failure of the Vectran component in the string or cable would manifest itself over time.
These issues can be managed by adopting good maintenance procedures and improved string waxes- waxes which lubricate the strands inside the string, slowing the breakdown of the Vectran component. For a compound, this lack of creep produces a longer-lived tune state.
Some recurve shooters also like the idea of a creep-free string, despite the fact that one can re-twist a recurve string in a matter of seconds. The lack of elasticity and the resulting sharp spike in load that takes place every time the bow is shot with these materials can take a toll on limbs and other components. As the blending processes for these materials have improved to address the harshness, a somewhat larger number of shooters have gravitated to these materials.
Even the very finest string materials can be wasted, if certain elements of string construction are overlooked. Well-constructed bowstrings all share a number of key features which enhance performance, durability, and reduce variability over time. One of the most important of these is the consistency of strand tension during construction.
Incorrect or uneven individual strand tension can cause the string to change in unpredictable ways, especially when going from cool to warm conditions. Incorrectly tensioned strands can even cause an imbalance, causing the string to load at different rates from shot to shot. This is partly related to the fact that strings experience peak loads of many hundreds of pounds for brief moments when the limbs recover. One trick to help ensure that a well-made string is going to have good strand tension distribution in use, is to take all twists out of the string, string your bow yes, the brace height will be low and let it sit overnight.
You can also take a few shots with the untwisted string with an arrow on a relatively close target. This will help force the tighter strands to stretch a little and allow the looser strands to take up their share of the load. When re-twisting to achieve correct brace height, be sure to twist in the direction that tightens the center serving. You can determine this immediately on an un-tensioned string simply by grasping each end of the served area between thumb and forefinger, and twisting.
One direction will be harder than the other. Twist into this direction. Answer: You can't. It's a patented product made by Mathews from a specially constructed material. You can make standard two color strings. Question: What is the best center serving to use? Answer: 62XS and Powergrip both grip well and have high durability. Halo is very tough and liked by many finger shooters.
Question: What is the best end serving to use? Answer: For the ends on modern compound bows, twisted Spectra material is usually the best. If smaller diameter end serving is needed, we offer 2X twisted Spectra a little smaller than 3D ; or " twisted Spectra which is approx. On traditional bows, nylon is a good bet. Question: How tight should serving material be applied? Answer: Tight enough to hold the serving in place and stop it separating.
That's not very specific but what it means is that if you serve too tightly, there may be problems. In the center, you are crushing the bowstring material which can cause problems at a point where flexing occurs, and at the ends, if the serving is too tight, it "cracks" open when bent around the cam, especially if the bow is fitted with a radical cam. So, experiment with serving materials with some adhesive coating, such as 62XS and Powergrip.
Answer: Not very much. Both products are HMPE high modulus polyethylene materials. These would be the number of filaments and the actual makeup of the yarn. Note that Spectra is not available in heavy size yarns needed for making archery bowstring material. The high strength results in very low creep. Technical information about both products can be accessed through the Internet if you are looking for additional technical data. Question: Does x or X fray?
Answer: All bowstring material will fray or fuzz if it's not properly maintained, meaning regularly waxed, so I guess the question is - Does fray more than other bowstring materials? Early production of bowstring material included fibers lubricated with silicone. It was found that the silicone would not blend with our standard bowstring wax applied during manufacturing. This caused material to dry out quickly and a dry string will fuzz of fray.
The fibers are no longer lubricated with silicone. We now use a special lubricant which blends well with our current production wax. This means that the stays well lubricated. All current productions of will show no more fuzzing or fraying than any other bowstring material. The lower the Vectran content, the higher the durability, the faster the arrow speed, and the lower the fraying.
Question: Do bowstrings provide the same performance on different bows? The width of the wheel tracks and design of the compound bows can make a difference. On some compound bows, particularly those with narrow wheel tracks, the use of string material with a high percentage of Vectran has resulted in problems such as sudden catastrophic failures.
So, the answer is really that any opinions given by archers on string material relate directly to the bow they are using and it is wrong to assume that the results will be the same on other bows. Question: Bowstring material used to be made from Dacron, then from Fastflight. What are these materials and which one is best? Breakages are rare with either material. Breakages can occur because of abrasion, rough spots at the ends of the bow, etc. Which is best? Bottom line We've recently added SK78 for Crossbows.
Question: What is the best bowstring material for a modern Recurve bow? Answer: First it is essential to be sure that the bow is designed to shoot with the modern, high tenacity bowstring materials.
Any doubt, use Polyester Dacron to avoid limb tip breakage. Which string material is best for recurves?
