Hey All,
Not sure if this is the right forum for this but I need help figuring out the right size arrow nock.
First off I'm relatively new to all this.
I made my first board bow, fitted with 14 strand b50 string. The strands are 7x7 Flemish twist. I bought some arrows and the nocks fit absolutely perfectly on my bow string without a serving. I served it with .018 string and now the nocks are way too tight.
I like the string setup, want to keep it served for sure, any size serving will render the nocks on these arrows too tight since they are perfect with no serving. I really don't want to go less strands on the string and so replacing the nocks seems the way to go... however I cannot find ANYTHING to help finding the right size nock for different size strings.
Anyone have this secret info?
Thanks a bunch in advance!!

What is pull weight of your bow? I use 5 lb/strand to determine # of strands for a string. Could fewer strands be used?
-
With plastic nocks you can put them in hot water for a short time and spread the ears apart so they will fit the string.
-
A serving will almost always "pack down" a little after 100-150 shots and the nock fit will loosen. How many times have you shot with the new string? I would be sure the serving is settled before you adjust the throat size. A tight nock fit will cause erratic arrow flight, same as a loose nock fit.

I prefer a loose nock fit and that's how I make my self nocks. I rarely get good flight from a tight fit.

If your serving is well waxed, you may be able to gently squeeze it down with a pliers. Otherwise, I think Pat B and Pearl got it covered. Nock should more or less just hold the arrow on the string without dropping off.

Jerry, my arrows won't stay on the string by themselves. I have to hold them because they are so loose but that's how I like it. I also nock my arrow over the nock point unlike most other folks.

I like my arrows to stay on, I nock an arrow and hold the bow towards the ground and give it a few shakes it should come off after 2-3 shakes, if not then its to tight. If its over tight then it can affect arrow flight but a snug fit does not have any affect on it in my experience.
