Whats my Bow

Here is a listing of the bows available on the market to buy and one of them will be yours if your having dificulty in knowing what string or cables you need for your bow.


Does direction of string twist cause arrow to twist that direction

So there is quite alot of discussion about this topic.  So consider your vanes first, the helical or slight twist of the feathers or vanes is what causes the arrow to spin in the direction of the angle or twist as the arrow is shot and passes through the air on its way to your target.  Now take a look at your string, if the so called twist of the string is to cause the arrow to spin or twist in that direction then your string would have to be at a bind so as it unloads its energy into the arrow it would cause it to twist. Which is really impossible for your peep sight would be spinning continually and never be in a position to see through it, and the dloop would also show the same spinning around as the peep sight.  The next part of the equation is that it would be spinning in the vertical direction and not the horizontal position as the arrow sits.  The last thing to look at for proof is your nock to string connection.  The center serving as it sits inside of the nock is loose for the nock is barley hanging on to the string by the teeth which under slight force should clip on and off the string.  So even if the string in the slighest way was to cause the arrow to spin with the loose connection of the nock to string the string would only spin inside the the nock.  And lets say your nock was on super tight, if the string caused the arrow to spin it would flip the arrow off the rest either hitting the riser or falling completly off the shelf.  So NO the twist of the string either clockwise or counter clockwise will not cause the arrow to spin in that direction.

I am getting some damage at the cable slide why is this happening to my string?

What causes this is that a very small piece of dirt or other foreign object has stuck to your string or in your Teflon slide and every time you draw and shoot its being pulled over this area cutting into the string or cable. This needs to be fixed right away by cleaning the Teflon slide and your string or by replacing the slide. If the damage is bad enough then the string should be replaced along with the slide to prevent this from happening to the new string. This is not covered under warranty.

After I install the new string and cables will I have to worry about timing?

Yes you will, every bow will need to have a little tweaking done to them to get the cam or cams set as close to what is called perfect timing. This will help the bow to shoot at its best performance level. Adjustments are made with the cables for timing. String should be only twisted to help align the peep sight if used.

What is your warranty policy?

Your new bowstrings and cables are warranted for a period 1 year for peep sight rotation, creep, serving separation, craftsmanship and manufacturing defects in materials from date of delivery. The use of a string separator to install a peep sight voids all warranty. Strings should be slack or loose when installing peep sights to prevent damage. Burning the string also voids the warranty. End loop servings are not covered under any warranty because of edges on pegs and some times tools are used to put loop over peg which can break loop serving. Any warranty work needs to be mailed in to us and there are no exceptions.

What is Pre-Stretching?

Pre-Stretching is where we put your string on a stretching machine and remove any slack your string will have so when you put the string on your bow its perfect and ready for your tuning to get your proper draw length and shooting style. Strings may still require a shoot in period.

How often should I replace my strings and cables?

This will depend on several factors such as cam design, shots fired and regular maintenance. With good maintenance a target or 3D shooter should replace the strings and cables every year and the average bowhunter every two to 3 years.

What type of maintenance do bowstring materials require?

It is very important to wax your bow strings and cables on a regular basis but this is often the most neglected step in maintenance. Brownell wax is formulated to be compatible with all bow string materials. If you shoot a lot or your bow is exposed to the elements, wax at least every two weeks. Never expose your bow to extended periods of extreme heat such as in a closed vehicle during the summer months.

What is a Control Cable?

A Control Cable or Aim Cable is a cable that has no split on either end like the buss cable has. The control or Aim Cable connects to the top and bottom cam and NOT to the axle pin bushings located on the outer limb tips. This cable looks like a bowstring without the center serving. Aim Cables have one end that connects to the cam and the other to the inside of the limb on the axle pin.

What is a Buss Cable?

A Buss Cable looks like a (Y) and is the cable on your bow that connects  the bottom cam to the top limb and on the top cam the buss cable connect the cam to the bottom limbs.  The yoke ends connect to the outer bushings on the axles and on some bows inside the limbs next to the cams or they can be installed in a slot cut into the limb tips.  There can be 1 or 2 on some bows.

Why do you offer so many options?

We offer so many options because we want our customers to have the same options we ourselves would want to choose from.

What is a tri-color string?

Tri-colored string is a string that has 3 different colors on one strand of string. It is not 3 separate strings in one.

Can I use the same material for both string and cables?

Yes you can, all these materials for compounds and some recurves for they have outstanding strength and stability.

Which material offers the greatest speed increase?

Astro Flight offers the greatest strength per strand. And for speed usually a increase of 3 to 4 fps is standard but some bows have had an increase of almost 10fps after proper timing.

What the differences in material per string brand?
  • Astro Flight material is 100% HMPE a Ultra-high-molecular-weight polyethylene.
  • XCEL and 452x are blended materials made of Dyneema and Vectran.
  • 8190 is 100% HMPE with a strand of gore fiber.
  • BCY X is 83% SK90 Dyneema and 17% Vectran.
How long does it normally take to make a Custom Bowstring?

It usually takes 5 to 10 business days but during the hunting season it may take up to 2 to 3 weeks to get your order made and shipped out. It pays to look at your equipment and order ahead of hunting season so there is not much of a waiting period to get your new strings.

How do i measure a single cam set?

When measuring your string start with the total length A (0-98), then measure the end serving closest to the center serving, B (0-16) then if you have a STS system measure that, C (22-24) if not then C is the next measurement. Now measure the center serving C or D (26-31 1/2) then the serving that goes over the idler wheel D or E (44-61) then measure the final end serving E or F (0-8)

Do the same measuring for your Buss Cable A = Total Length A (0-45) Now measure the serving end of the cable connected to the Cam B= (0-8) Now measure from the Yoke Ends to the string serving. C= (0-8) And now finish measuring the serving from the start of the serving at the yoke to where it ends D =(8-10)
