black widow vibration?

[Morgan Anderson]

I just got a BW takedown and there is a vibration in the limb tips when I shoot. I tried a tip protector, 3 different types of string silencers, brace height, and limb savers and I cant get rid of it.... any ideas?

[S.C. Hunter]

No limb twist? Do the limbs seem to be flush with the riser? The problem can be lower near the riser, the limb tips being the most distal portion of the bow will be where the problem is noticed. It is sort of like the rock in the pond the ripple starts in the middle and moves outward. Just a thought. The only other thing I can think of is if the arrow is to lite.

[Morgan Anderson]

No limb twist. I don't think its arrow weight either.

Brace height needs to come up a bit is my bet.

ya mine likes it about 8 5/8 for the bh.

I picked up my first BW a while back. It's a used,1 pc PTF. I couldn't get it as quiet as I like with the FF string that came with it.

 I made a couple strings using TS1, 450+ and put bowhush and hush puppies on it and while it helped, I still wasn't happy with it.

 I twisted up a B50 dacron and it now just has a nice thump with the bowhush and puppies. I'm pulling right at 48# at my draw and shooting a 530 grn fir arrow, it still throws em 170 fps.
 
 Try a B50 string if you get a chance.

Out of curiousity what model and length BW is it?

[jarhead_hunter]

I agree with the string change to B50 idea.

I really have seen nothing but problems with the Fast Flite type strings....

I also would suggest that you make sure the limb bolt(s) are tight.

In reality ff strings should make for a quieter bow. I highly doubt that the string is the problem. BWs like a high brace . Perhaps the string is too short though. The kind of vibration you are describing is caused by poor limb timing or lateral instability at a low brace height. Usually it can be correct4ed by simply twisting the string up until it stops. Sometimes that might even be 8 to 9 inches. God Bless yuj and good luck, Steve

I'll start by saying I don't own a BW or have I ever shot one, though I plan on changing that. I know some people like FF which is great for them if you like it then I love it but I'd like to share a quick story with you. A few years ago I got into longbows and decided to get one, well I didn't by used then so I ordered up a new one from a well respected bowyer. When it came in it had a FF string on it and no matter what I did I couldn't quiet this thing down so as a last resort I changed to a B-50 and you guessed it the bow was whisper quiet. I've never been a fan of FF just because I don't like the way it feels on my fingers when shooting it and now because I find it to make a bow louder.

its a 62" MB recurve

I have owned several Widow takedowns and they can be a challenge to get quite I wrap the top of my string where it touches the limb with wool yarn and for silencers i have had the most success with the widow spiders and I have tried everything.

I've had 2 FF equipped BWs, both were quiet and fast.

I had one get a little noisy, some vibe, after a good downpour had the flemish twist string drop the brace substantially (and the string had hundreds of shots on it, had held brace fine up until the drenching).

[Bjorn]

The FF type string is unlikely to be the problem. On problem bows I have quieted them using 4 silencers instead of two. Place them on the 1/4's and the 1/3's. I agree with the need for a higher brace.
Also wool yarn is surprisingly effective at silencing a bow.
And lastly check your arrow weight. 10-11 gpp is good.

I have a 58" PSAX 58# @28" that is pretty quite.  8 5/8" BH.  600gr arrow.  Wool yarn silencers and wool yarn wrapped around the string at the tips(Bow Hush and Hush Puppie configuration).  Also have velcro in the string grooves but I could probably omit that with the Bow Hush.

I get a little vibration from my Great Northern bow quiver that mounts to the limb bolts if I don't position the adapters just right.  Same thing with my Habu that uses the same quiver setup.  I can hear the brass insert that fills the tapered portion of the bolt hole rattle.  Makes me not want to take it down.

[Hookeye]

I always run a pair of wooly whispers, seems to work great.

A light weight quiver bolted on may offer some increase in overall weight, help tame some vibe, but IMHO it needs to be of a rigid attachment style and of substantial weight.

I find the GN stuff to be too light and flexible.

Better to make custom brackets of stiffness and bolt on a Delta. Quiet and helps remove some of the bow movement at the shot.

I did in experimentation find that a 400gr arrow from a 55# SA2 was a bit shocky and loud. 480 grain arrows made things completely different  

I've broken my wrist several times and it used to be pretty tender, couldn't handle hardly any shock. A well tuned BW with a decent weight arrow offered zero problems.

It's probably brace height as said along with you may try loading the tip of the arrow some with heavier heads, brass inserts etc.
It also may be if your shooting three under and Widows tiller is typically 1/4inch positive on the upper limb you may be torqueing the bow some, Sixby would be the expert for that solution if it was the case.
