Hey All,
I was wondering if you guys have a certain guideline (personal test...?) to determine the correct fit for the arrow nock to the string (serving)? I am shooting GT 5575 w/ the stock nocks and when I nock an arrow it makes an audible "snap".
It is something I am very unfamiliar with and guess my questions would be.
1. Does the fit affect arrow flight?
2. Does the fit affect the quietness of the bow by "twanging" the string on release?
3. How do you all adjust the fit?
Thanks ahead of time for any response.

Personally I test my nocks by putting the arrow on the string andpointing it at the ground. I then give the string a tap. If the arrow falls off, everything is good.
If the arrow falls off before I tap the string, then the fit is too lose. I may try a different nock, change the serving, or boil some water, dip the nock in, put back on the string and squeeze until it cools.
If the arrow stays on the string after the tap, the fit is too tight. I can either try a different brand of nock, or re-serve the string with the correct thickness serving.

boiling water fixed the problem for me as well.If its to tight, after dipping in the water just push it on the string without squeezing and that will open it up a bit.

If the nock is too tight, it will slow down your arrow speed and cause inconsistent accuracy, especially with broadheads. In extreme cases, it can also cause your serving, maybe even your string,to wear out prematurely.
BobCo's method is what I use too... for using fingers release. For mechanical release, I want the fit just a smidge tighter. Certainly not tight enough to make an audible click though!
The boiling water trickworks on the old style glue on nocks but it doesn't work onmost of the newer nocks, like the ones GoldTip uses. I've swiped one of my wife's fingernail boards and used it to sand the throat wider on those and it worked pretty well. I was careful to make the same number of strokes on each ear of the nock to make sure I kept the throat centered though.Reserving with smaller diameter serving thread or trying different size nocks is probably best.
With your knowledge you still file the nocks? OK,, just razzing you a bit.

The absolute best way to achieve good fit is to find the right size serving and reserve. That's why serving is available in several different diameters.

I'm an aerospace machinist by trade. After making high precision parts for satelites, helicopters, fighter planes, missles and space shuttles... It's no big deal to file a nock... and get it to closer tolerances than it comes out of the factory.
I will give it a shot with the nail file. I just wasn't sure if this was wise or not (weaken the nock or something). I have also been looking at other nock options. It looks like I might want to try Tune a Nock FS with a Super Uni Bushing. I am having a heck of a time finding the proper size of Super Uni Bushing. Goldtip doesn't have a sizing chart that I can find online, and either does Easton. Any suggestions? I am shooting GT 5575 arrows.

I shoot Ultralight Pro's and one of the btter options is Easton CB bushings and G-nocks. Whatever, you're looking for a bushing that fits a .246" ID arrow.

Here is another method for the seriously obsesive compulsive courtesy of Rock Monkey @ALC website:
"Use a dial caliper and measure your serving at your nock point. Looking at a drill bit chart find your serving's diameter and go down one or two sizes of drill bit. Hunters may want to go down 3 sizes. Use that drill bit you selected, chuck it into a drill press, turn it on and 'tap' (nock your arrow on the drill bit) your nocks. Don"™t push hard, all you want to do is cut out the excess material from between the ears.
What does this accomplish? Drill bit sizes are absolute; a nock's groove is not. Molds have a tolerance. Different molds have different tolerances. Occasionally, you will get the wrong size in a bag/bin. by measuring your serving, and finding that bit, you are making ALL your nocks the same size, in groove width, thereby giving you consistent nock fit. You may want to tinker with the correct size for you. Some guys like a harder snap than others. Me, I like em just enuff to hold on and no more. Hunters will like it since it"™s quieter."
If it's made of plastic ,Boiling hot water will soften it . Some may need to be left in a little longer but I haven't found any it didn't work on.Although my experience isn't as vast as most of all the archers onboard, plastic melts......you can also graduallybring it close to a open flame and rotate itthen put it on the string
