Recurve limb noise

[Paul_R]

The limb noise is really noticeable on my 60" recurve (Predator Hunter). The string is quiet but the limb really hums. My short recurves don't do that at all.

Anybody else notice more noise with longer limbs on recurves or am I just lucky? What can be done to quiet things down?

What type of string is on it?

It has an SBD 8 strand with beaver balls

Contact the young ladies at Bow Hush...bet they can provide a fix

Limb Savers are great if you can stand the looks.

Are beaver balls evenly spaced?  Usually put that way. Slide the bottom silencer up the string 4-6 inches. Will look weird but seemed to help quiet my recurves. There's a word for it....but doesn't come to mind.

I would not consider 60" a long recurve ... are you padding the limb tips ? I would switch to wool or cat whiskers for the string and pad the limb tips. If that does not work try adding limb savers too. I have never had a Predator bow but have had many 60" bows and the above suggestions worked well.

Measure the length of the string where it touches the limbs and divide by 4, then place your silencers at that measurement down from each limb tip where the sting makes contact. So if you have a 56" measurement put your silencer 14" down from where the string contacts the limb.

Good luck ...

Search- heterodyning. Well put elkken

Thanks guys!

Try adjusting your brace height. There seems to be a sweet spot for some bows to be their quietest.

[Bobby Urban]

X2 on Walter Mauney's advice.  All good stuff above but getting the brace height perfect before adding and silencers will be the best place to start imo. Every bow will shoot best at a particular brace  -  even for different shooters and draw length.  Start with taking it as low as you can until it gets loose(may be where you are at)  Then bring it back up a few twists at a time until it gets solid.  Add string silencers and put them at thirds of the distance from where the string touches the limb - not the string length.  They will look deeper(closer to center) than most are used to but this is where they will do their best work.  It is a physics thing and has to do with harmonics. Perfect is dead center but that is obviously not an option so thirds is 2nd best.  If it is not as quiet as you want at this point add limb savers to the inside of the limbs at the fades.  If all this does not work get heavier arrows or a new bow.

I've done brace height adjustments and it has very little effect on this bow, it sounds the same throughout the range. This bow just has noisy limbs. And it's just this particular bow. It's a hummer and mostly from the limbs not the string.

[Swamp Yankee]

Sounds like a good candidate for limb savers to me.  Yeah, ugly and not "traditional" to most; but they work for me on recurves.

[Gordon martiniuk]

another way too it is to add a stabilizer bushing and put on  stubby rubber limbsaver  on her and yes the others are right on ,, different string and try higher brace hight  is the starting point then limb savers then the stabilizer bushing  if these don't help trade the bow

[TGbow]

I've found that different bows like different string materials. Even using a string that works well on one recurve will not have the same effects on another recurve. I had a recurve that was noisy with d97 but an xs2 string wss really quiet.
Dont know why but it made a big difference.

[Steelhead]

Limbsavers after you get everything else as good as you can.They  definatly work!

Put them 3-4 inches above the fadeouts of the riser.Ihave played with them alot and for me this is where they should go on a (traditional bow limb).They will dampen limb vibration very well thier.Better than at the fadeouts or near the limbs ends where the instructions say to put them

I even use them on my hunting bow that is already quiet without them to make it virtually silent.

Talk to Pierre from SBD. I am sure he is willing to help and probably can solve this for you. Maybe you don't have the right string length.

I have 8 strand SBD strings on my 62 inch recurves and a 6 strands string on my 62 inch hybrid longbow. No issues at all. I shoot between the 8.8 and 10 gpp.

I have 8 strand SBD's on all my bows and the Predator is the only one that makes any noise at all. It's also my only 3 piece TD bow....

heterodyning helped me with a Shrew Scout recurve. made a substantial difference when compared to equal silencer spacing.

My RER and Phoenix are 3 pce TD's as well. No issues.
