String makers - Is there a formula for where to place the serving on new string?

[Tedd]

While I have made dozens of strings over the last 15 years. I always use a bow square to determine the location of the serving. That way I can minimize the length of the serving.
Now I have a new bow on the way and just made string for it. I need to apply the serving. Is there a standard distance from top or bottom or center to place the serving? How does a string supply company know where to place the serving when a customer orders a string?

Tedd, I have settled on 7" s centered on the string for most of my servings. (Unless a customer specifies something different).  

This seems to give adequate coverage without too much extra weight on the string.

The arrow rest on most bows is cut 1 1/4 to 1 3/8 inches above the center of the bow (Some are cut as much as 2 inches above center).  I usually work from the shelf with a 7 inch string, two inches above the shelf to about 5 inches below.

I do the same as Jerry.

I measure to the center, back up 3" toward the bottom loop, and serve up a total of 8".

There are several threads on this subject if you do a search on string serving.

Some time back I asked why the serving usually extends so far below the nock point, thinking that would just create more wind resistance for the string. Turns out there is a good reason. It protects the string from rubbing on the arm guard.

If you are wearing out strings hitting the arm guard, there is something wrong bro... you might want to consider a slightly different wrist rotation, or possibly using a higher brace height or both...... If your string is hitting the arm guard it's going to effect your shooting accuracy.
