Nock fit

[chryd]

I've got some Beiter hunter nocks to try out but they are too loose on my string - they stay on the string ok, but they can wobble about and will slide on the string under their own weight. I thought they were supposed to be the same size groove as the G-nocks I was using (large groove g-nock, the beiters are 12/2)...

My string is 22 strands of 452X, with a 0.021 center serving (BCY #62).

So, I have two questions for those of you that use Beiter hunter nocks

1) Are the Beiter nocks supposed to be this loose?

2) What size string/serving do you use to get a decent nock fit?

Cheers,
Chris.

I don't use beiter nocks, but the answer to your question is no.
The nock fit should be tight enough to hold the serving, but loose enough that they disengage with a sharp tap on the string (arrow on string, pointing at the ground, then you tap the string hard with your hand)

Unfortunately I think nock fit is a bit like "international fit" limbs. - No real 'standard' just different companies trying to achieve a similar thing.

I have recently experienced the hunter nocks on some arrows I was trying and found them to be looser than large Gs as well, I then put large pin nocks on the same arrows which were a little tighter than the Gs!?!

24 strand 452x and 0.21 serving should work a treat and also be nice to shoot.

The keyhole should allow the arrow to rotate on the string without turning the string with the arrow. The slot is narrower than the keyhole in order that the arrow is pulled by the string and not left to fall off. Any up and down is taken care of by the nocking point that is built up above and below the nock. The thicker the nocking material is, the more it will pinch on the nocks or the nocks will push the nocking points apart(whichever gives in first I suppose)
Low profile nock points can fit closer to the nocks of the arrow and less up or down movements will occur.

I have found somewhat in the face of conventional thought, that a quite tight nock fit enhances good arrow flight, on the back of finding optimum brace height, where bow string deflection off the ears of the nock is eliminated or greatly reduced, now picture those nocks ears spread further apart by a thicker center serving this will have the effect of improving the ear of the nock clearance, I believe a lot of the development and popularity behind the Easton Pin nock system was the fact the aforementioned nock "ears" are a lot shorter than those of the "G" nock or the Beiter type.

Buzz that makes a lot of sense.
Tight nock fit comes in two sorts, nocking points close to the nock and string thickness. I was told by the owner at Magnoks that the string should rotate inside the keyhole so the string can twist/untwist without trying to turn the arrow left or right. Short ears makes sense though.

I gave up on normal nocks ages ago.
I use Magnocks--- no more problems.

Apart from they are not FITA legal the last I heard.

I would consider the rotation imparted on a recurve bow is considerably less than that of a compound, obviously taking quality of loose into consideration. However the rotation in a compound bow string is very apparent just need to try aligning a peep sight will confirm this, plus I would say on a compound that such rotation, like string good string clearance is an essential consideration be attained within the first 6" of string travel (with having such a low holding weight initial deflections and rotating strings will be magnified over that of a recurve with its draw force curve)
