HELP. Nock Fit on string

PeteA · February 17, 2010, 10:08:00 AM

Looking for some guidance.
I am shooting a Bear Takedown 50# @ 28, drawing 28. Split finger. Shooting 2016 xx75's with UNI Bushing nocks. It seem that these nocks have 2 positions when they snap onto the string. The second position (deepest) is very tight on the string. The first position is less tight and give a better arrow flight. It is still secure on the string so I feel I am not in fear of a dry fire. When you nock the arrow I can hear one distinct click for the first position and a second click for the deepest position. If I then pull the arrow off the string while it is in the deepest position it is actually hard to get it off the string.

Can someone let me know if this the case with these nocks?

Pete, in general your nock fit should be as light as possible and still keep the arrow on the string. A slight bump should release it. It can have a dramatic effect on your tuning if too tight.

I HEARD YOU CAN DRAG A CHAINSAW FILE THROUGH THEM SO THEY DONT PINCH SO TIGHT, AND GET BETTER ARROW FLIGHT. (JUST WHAT I HEARD.)

I have some arrows with Uni Nocks and also find them to be much tighter than most others.
There are not actually two positions, though it may feel like it a bit. There is actually just one "snap" (after a "flat", that might be what you are feeling).
If you reserve with a smaller dia serving, you should be good. Cant suggest what size serving, as that depends on what string, strand count, et. you currently have.

But UNI-NOCKS are definitely tighter than average.

Pete, I use the exact same arrows in my longbow (49# @29). I know what you're talking about with the "two-snap" and tight fit issues (really tight, actually). I was having erratic arrow flight until I filed them down with an emory board (fingernail file). Got 'em just right, no double click, and arrow flight much improved. Took a while to file a dozen arrows, but totally worth it. I'm certain that tight fit was skimming off some fps, too!

Hey Pete
I use a emery board, slip it in the nock and file it down a little at a time.Nock should stay on the string when you point it down and come off with a good tap on the string.Helps to stop shooting left.

All good advise guys thanks much. Asked the same question on "Another Site" didn't get as many replies. One I did get suggested changing to Easton Super Nocks. Seems these fit the the shaft same as what I am using now but is a wider dia. for the serving.
I think the emery board is the way to go for me.

Thx

I also had a nock problem with them. I also used a fingernail file to solve the problem. On the other hand I also with other shafts have the nocks too loose. Had to use dental floss to keep those on the string.

Smaller diameter serving (if you make/serve strings) or emory board are your best solutions. With the arrow on the string and hanging down, it should stay on the string until you tap the string and then it should fall off. That's the fit you're looking for. Always have your string contacting the deepest part of the nock. If not, you risk breaking a nock and basically having a dry fire.

Just a note of caution, I have heard of people that will file/grind the nock to increase the size of the gap and had failure of the knock. Supposedly due to the nock being weakend. Now, I personally have filed nocks to fit strings for over 10 years now and have not had one failure.

PeteA · February 17, 2010, 05:14:00 PM

Just tried the filing concept. 10-15 strokes on each side. Still get a click on the string but they release upon a solid tap on the string when pointed down. Still have a 1/2 dozen to go but the first 1/2 dozen sure do fly better. I am now grouping within 5 inches at 17 yards.

Thx Boys.

Can also stick the nock in boiling water for a few seconds and then fit them to your string. A little side to side twisting opens them up just enough for a good fit. If ya twist too far, just stick them back in the boiling water and put them on the string and pinch it back down. Seems to work for me.

You can always buy new nocks of a different brand,Whats 4-5 dollars compared to good arrow flight.

Another solution would be to get 2016s with a swaged nock, and glue on Mercury or Bohning Classic nocks.

2016 is still available as a Legacy shaft, and probably some other Easton shaft lines. I am sitting on a bunch of old xx75s. :D
