Took off 2nd serving and bow went nuts!!! help!

[J. Cook]

I have a skinny string -- 10 or 12 strand (can't remember) and it had the standard serving then a shorter second serving on it.  But that made it just a bit too fat for good nock fit, so I cut it off and the tune of the bow went haywire!!!!  The arrows are flying HORRIBLE and shot placement is way off!!!!  How could removing a secondary serving screw up the tune that much????  Any ideas?

[KHALVERSON]

did you recheck your brace height
im thinkin that maybe  removing the second serving has allowed the string to stretch
just my .02$

How do your nocks fit now? Do you have two string nocks? I'm betting your previous tune was with a more stable launch of the arrow with the tighter nock fit. Now with wiggle room it's showing the imperfections of letting the arrow loose.

[J. Cook]

we aren't talking a slight variation in tune -- I'm talking it went from shooting as good as I can possibly tune one in terms of visual arrow flight, to whipping 6 - 8" on the back end and hitting over a foot high!  Drastic difference, so much in fact that I thought my limb must have fractured on the first shot!  

The nocks do have some play, but do snap on.  I shoot 3 under also.

[Bud B.]

Double nock? And did you get the right nock height adjustment back? Something sounds off like you said. Is it possible your release was affected?

[J. Cook]

I can't see how my release would have changed.  I'm kind of at a loss on this one -- I could understand a minor change due to stretch, etc.  I'm going to spend some time with it tomorrow -- maybe it is just that finnicky of a bow and I just had always lived in the "sweet spot" on it.  Too much tinkering gets me every time!!!!

I say it's a noc fit issue, multiply that with the string noc being out of place a bit and she will be wild as a bull. I would also think this means your arrows are not spined correctly. The limb sound was probably a nock smacking off the riser not the limb. Heck maybe I'm wrong and you were having a bad release day or form problem. Hope you get it figured out, I've been down that road and it will make you pull your hair out.

[Bud B.]

Not your release, but what the change has had as an affect on your release.

Were both layers of serving the same material?

The variables are nock fit, nock height, and brace height.  Everything else is noise. Deal with each, one at a time, beginning with brace height. I suspect your nock height is low. Good luck!

Sounds like your mocks are now a sloppy fit.

I've had the exact problem before. I'd say your arrow is sliding down the string on release.  Add a nock below your arrow. Just  use a piece of dental floss. To fix your nocks,  you can soak them in some hot water for a few seconds and then pinch them on your string, or, you can wrap some dental floss in between the nock points.

Second, what Bjorn said:

I would add Nock fit, snap on and off easily. Light strings can stretch, watch for a broken strand under the serving.

I'm going with what Bud said. Really the only thing that's changed from what I'm reading...Art

here's a thought: the skinny strings are used typically b/c they are lighter - leads to faster string. Removing 1/2 of the servig = removing a significant amount of weight. This could result in the string traveling much faster upon release. IF this has happened, then retuning based on this new string speed is almost unavoidable. I understand you say it went entirely crazy and this may seem too easy - however, i wouldn't guess the string w/o the extra serving wt would tune exactly the same (mainly bh) as the string with the serving. hope you get it worked out.

From my experience, just doing what he did, won't cause erratic flight.  It might make his arrows act weaker, but it won't be cause for a nock height adjustment. I still say that his arrows are sliding down the string upon release. Tighter nock fit will help, but a double nock set is the answer.

[J. Cook]

My brace height and nock point are now the exact same as before...the nocks are carbon express snap-on style.  They are not loose enough to fall off the string, before they were so tight that if I didn't shoot the arrow, you could not pull it off the string without it pulling the nock out of the arrow.  It's now shooting a solid 15" high, and wildly tail whipping in what seems like all directions.  

In terms of arrow tune, I had worked very hard to tune arrows to this bow.  I'm confused how removing a partial serving could totally change the bow to something unshootable at the moment.  

One of these days I'll learn "if it ain't broke -- stop tinkering!!!!!!"

[Jeff Strubberg]

Well, if you tuned to a nock that tight, then your tune is definitely off now.  Basically, you tuned to accept a problem, then removed the problem.

You're definitely going to have to retune.  An arrow nock should never be that tight.  That's a good way to split a nock and dry fire.

J:

Several of the posters have asked if you have a second nock point tied in below your arrow nock and I have not seen you reply to this...

Do you have a second nock tied in place?

[Mike Mecredy]

You could put the serving back on, and adjust your nocks.
