(Q) 1.  How long does it normally take to make a Custom Bowstring?
A   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.
(Q) 2. What is the difference between Astro Flight and Xcel and 452x and BCY's X and which one should I use? 
For materials to use to get the best performance we see Astro Flight and BCY X as the 2 materials that perform fantastically.
A  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 and BCY X is 83% SK90 Dyneema and 17% Vectran. 
(Q) 3. 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.
(Q) 5. Can I use Xcel or Astro Flight or 8190 and BCY X and  452x for both string and cables?
A YES you can, all these materials for compounds and some recurves for they  have outstanding strength and stability.
(Q) 6. What is a Tri color string? 3 seperate strings in one?
NO, a Tri Colored string is a string that has 3 different colors on one strand of string.
(Q)  7. Why do you offer so many options?
A We offer so many options because we want our customers to have the same options we ourselves would want to choose from.
(Q)  8What is a Buss Cable?
A   A Buss Cable is the cable on your bow that connects to either the top or bottom cam and on the other end it connects 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. They have 1 loop on 1 end and 2 loops on the other end.
(Q)  9. What is a Control Cable or Aim 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 bushings. Aim cables were mainly used on alot of older hoyts. 

(Q) 10. What type of maintenance does Brownell 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.

(Q).  11. How often should I replace my strings and cables?
A. 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 bow hunter every two years.

(Q) 12. What is Pre-Stretching?
A.  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.
(Q)  13. What is the best string for Hunting and Target?
A.   All the materials we offer Fury, BCY X, Astro Flight, 452x and Xcel  are without a doubt the best string materials for all shooting situations from Target to Hunting to just shooting with friends.
(Q)  14. What is your Warranty Policy. 
A.   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. Also 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. 
(Q)  15. After I install the new string and cables will I have to worry about timing? 
A.   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.
 (Q)  15  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 any warrantee.
(Q) How to measure a Solo Cam String 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)
