Title: The carbon "tink"
Post by: 4dogs on February 09, 2015, 12:01:00 AM
I know that the bow isnt noisy...just a different pitch etc..but the pitch is still bothersome to me. Can anything be done to quiet the "tink" noise that carbon limbs make? I shoot a heavy arrow, have a on the skinny side string and have string silencers that work very well and a rubber mounted quiver. Its just that #$%$$@ "tink"....limb savers maybe?  What do you guys think?  Guess I should tell that it is a aggresive D&R hybryd longbow.

interested in what people have to say here. i have  a border recurve that is a little louder than the bob lee i used to have. it's not bad, just not as quiet.

I know exactly what you're talking about.  Yup its just a materials thing.  The aggressive designs have it a little more...hey, those limbs are traveling fast eh?  I have always had better tone results with a heavier arrow, especially past 10gpp.  Well constructed rubber whisker silencers also seem to help.  Sometimes lower brace height also believe it or not...less string tension can lower the tone depending.  Limbsavers?  Meh.  I don't notice that those help much but they sure are ugly!  Another consideration is string material.  What material are you using now?  You may want to try something new and see if it helps.  Sometimes it does.

Check out Hushpuk. You can move where you need because the do not use adhesive to fasten. Just an idea. Good luck.

I have two bows with carbonn limbs sorry but, I don't know what noise you speak of and, I shoot light and heavy arrows out of both.
Gordy Moray 68" 55# @ 28" R&D LB

Morrison Shawnee 64" 56 @ 28" foam/ carbon limbs R&D LB.

I had a morrison with Carbon/FC limbs, no tink.  I now have a Sas with 2xCarbon, no tink.

I did shoot with a friend a couple years ago and there was an audible TINK every shot.  He thought it was his bow quiver and in the quiet of my back yard, the TINK was quite loud!!

So we took off Quiver.  TINK!  wasn't that! then I stood close as he put an arrow on the string and shot...TINK!

Turned out his arrow nock fit on the string was a SNAP fit...when it released, there was an audible TINK!

point the arrow at the ground, tap the string and it would NOT come off... we sanded ONE nock slightly till it released with a TAP on the string but stayed put from the EFOC arrow pointed down.

NO MORE TINK! Fwiw!

He makes a good point with the nock fit.  Its something I didnt mention because its something I always address prior to shooting a bow.  Too tight is no bueno.

You seem to have done all you can do to reduce the sound.  May just have to live with it.  Maybe it's the arrow material instead of the bow limb material making the noise.  I have a couple of bows with carbon limbs.  No think there.

I have found the same now that I've been shooting carbon foam limbs on multiple bows for a few years. I can tell you the deer I've shot don't seem to react any different to them over my wood core bows. Its not any louder than a wood core limb report its just a difference sound.

I can tell you that sound is the loudest right where your head is as the shooter. I have had others shoot my bows and have stood beside it and  slightly ahead and the sound isn't near as loud. Give that a try it will make you feel better.

Anyhow, just to appease myself I have fooled around with a lot of string materials, padded loops and silencers and positions of them. After all that, brace height has the greatest difference along with your heavy arrow.

I am about to get a new light weight Fury FF string with Dacron padded loops and am really thinking that will also be an improvement.

In the end the increase in performance over wood cores, with no negative reactions from the deer is worth the trade off for me.

Well, my nocks if anything are a little on the loose side. I shoot almost 13 gpp for arrow weight and the string I use is a Rhino.  I may just have a perspective problem the more I think about it. I have been shooting a 68" reverse handle hill bow the last few months, since elk season closed and it is just silent..dead silent.  Just wish I could get my other bows that quiet. Like Orion said, I may just live with it. Thanks for all your advice fellers. I do appreciate it.

I have to agree with TJ. I had a Habu that I thought I should wear hearing protection when I shot it!  I stood beside someone else while they shot it, and it sounded no louder than any other bow.

A good string never hurts.

This may be the first advantage I've found to being hard of hearing. All my bows are quiet. No need to get all carried away trying to eliminate a sound I can't hear    :)

I have heard the tink with some of my carbon bows..

I went back to my longbows, I like the quiet shot.

I would go ahead and try the limbsavers.It cant hurt a bit to try them.I have quieted many bows using them and put them on all my hunting bows.Even the quietest ones.Who cares what they look like.When your hunting its not a beauty contest.

Put them 3 inches above where the fadeouts end.Thats the best spot in my experience using them.

I also like a larger than usual wool puff than most guys typically use on a bow that I am trying to quiet down.

Again, 4', think about limb velocity.  That 68" reverse Hill has thicker core limbs that are much longer than the hybrid.  Less efficient design so limbs are recovering slower (assuming bows are similar poundage) so tone is deeper and not as loud.  Think about two rifles, one is a .270 and the other a .223...the .223 is smaller and faster and has a higher pitched crack to it.  Oversimplified and silly analogy perhaps but it gets the idea home hopefully.

John, those hushpuks look interesting...I wonder how well something like that would work. Thanks

I've been shooting a carbon bow now (zipper) for a few months and don't notice anything.  It's very quiet actually but I use yarn puffs.  They're the best silencers out there IMO.

You mentioned your nocks may if anything be too loose.

That can create a "tink" noise too.

What can happen is while you draw your bow the nock could be sliding forward just slightly.

While not coming of the string there is a gap created between the nock base and the string.

Let the string go and it more or less slaps into the nock.

...just an idea..

I have a couple sets of ILF carbon wood limbs on metal risers. I do not notice any "tink" but I never really listened for it. Have heard others make this same comment before. I hear more of the arrow sliding on the rest.

I have a Shrew Classic Hunter that makes that "Tink" I hear it and I am deaf my buddies stand beside me and tell me I am crazy.   :dunno:

I have had success with Limbsavers in a similar situation and I have the last generation ones...I suspect the new ones are even more effective

Mark I can't explain how the puks stay put but they do had them on my bow for some demo shots and they stay put. Also low profile you can barely see them. Local company not far from me. They do not have adhesive on them so you can mount them anywhere.

Thanks John, Im going to give them a try.

To confuse things since some have said "I hear it but my buddies don't hear a thing", I have a woman that I work with that wears bells around her ankles.  I can hear one set of bells but not the other.  Other folks can hear both.  You may be encountering a higher frequency sound that "some can hear and some can not".   Just a  thought.

Yea Mark I have a few bows that I might want to give them a try on so I think I'm going to give them a go. I know several wheelie bow boys that shoot them and really like them.

You may be right Nathen. When I get my ears checked for work ( every three years) the tech always says Im hearing tones I shouldnt be able to.   :dunno:  A woman that comes to work with bells on LOL  thats great Ha.

Post by: TSP on February 16, 2015, 07:04:00 PM
I had two longbows with carbon limbs...both had that 'tink' you speak of and yes, it's annoying.  Tuning didn't help.  I no longer have them.

One thing you might try is raising your brace height above the recommended range...perhaps by quite a bit.  That worked well for one of my other bows (high end but non carbon) that had a a similar noise and wouldn't respond to normal tuning.

Good luck.

I've had two like that and I never could get rid of the sound.  Had to send both down the river.

Maybe a pair of limb savers or limb Jax. I have Dryad ACS CG longbow, I don't have a tink noise and my arrows are less than 10gpp by a tiny bit.

I fixed one one time it was a long bow and I was using hush puppies but I also installed Bow  hush....that tamed it for me

My Morrison limbs have no "tink" at all. Very quiet with just the regular "thump". Bob got those limbs just right.
