I recently went to a 16 strand 8125 bowstring and my wood arrows with traditional 11/32 nocks fit loosely. Should have had a double helping of serving at the centre. The arrows don't fall off when allowed to hang on their own, however it is a looser fit than my 16 strand Dyna-97 string so maybe I'll have it re-served. I'll check my little guy's nock fit for each of his arrows as well just to be sure. Can an extra (double serving) be done on my current serving or does the double serving need to be done at time of string construction? Again thanks for all the info.
BCY Fibers’ serving materials (one of the best quality manufacturers) come in sizes ranging from .014 to .030 inch diameters.
I have no personal experience with “double serving” except at the beginning and end of the job.
My understanding of good string tension is:
With the bow horizontal and the arrow hanging downward, a moderately sharp tap on the string about four inches from the nock should dislodge the arrow.
Some folks prefer a tighter fit for hunting. I prefer an easy “snap” fit that still retains the arrow well and keeps it from sliding easily vertically along the string. A little experimentation will give you a better idea of what is too tight and what is too loose.
It is known that too tight a fit will adversely affect accuracy.
We definitely don’t want too loose a fit.
I know it’s a poor answer to your question; however as in many things archery, experimentation will provide your answer. Make sure to document your testing and impressions for future reference. Compiling data like this can get confusing quickly if you have a memory like mine!
Your technician may be able to help you arrive at a quicker solution and then all you have to do is duplicate his tools/materials.
Using his guidance/suggestions on materials during trials will speed up results although your supplying the labor during the experimentation process will provide you with valuable practice.
You will find it is a surprisingly easy skill to acquire.
Good Luck1
