I'm having trouble eliminating vibration after the shot in my dale dye 58# recurve that is 64" long. Im shooting about a 600 grain carbon arrow.

I've tried two different strings (not sure material) but one was a lot thicker and the second is much smaller in diameter. The thinner string is better than the first. I've tried from 7.5" up to 8.25" brace heights. IT seems to get better as i go up, but how far can i take it before it is too far.

any ideas are welcome

thanks

Try bracing it at a height where your string just starts to leave the string groove in the limbs and go from there a couple of twists at a time either up or down until you find the sweet spot. This is how I do mine. Then I ad silencers! Do this with both strings. Lance.

Does it vibrate much in the hand? Making sure you have the right brace. Honestly I pay more attention with my hand than my ear with brace height, I was tuning my Bear TD 65# and once I was getting close I couldn't hear a difference, but I could tell by my hand.

My point is that you as the shooter are at the worst possible position to know how quiet your bow. Record yourself with your cell phone camera 7 yards away and you'll be suprized how quiet your bow is if it set up correctly. Shooting a 580 gr aluminun with a b50 endless string with brush buttons. And that's all it needs. But shooting it: it sounds loud because you're less than a yard away from every part of the bow.

Just some personal experience talking.

Type "silencer" top of this page, left hand hit keyword. A wealth of information an tips. No waiting for response.

Very odd since Dale's bows are normally VERY quiet. Can you determine where the noise is coming from? Is it string slap on the limb, the arrow on the sight window, the limbs not being tight, doe you have a quiver on it and is the noise coming from there? Just my bow is noisy really isn't a lot of help actually. Do you have silencers in the string already?

As for brace height....that's all individual and nobody can really give you that answer. If you are concerned about hurting the bow you won't.

I would wrap wool yarn from the loops down the string about 8". Id bet most of your noise is coming from that area.

thanks for the posts, here are some responses

1.Yes, it vibrates in the hand. It is a vibration that is kind of like a cyclical drone.... man, tough to describe. its not a vibration like I would feel in a compound where its like a fast tingle, the vibration is slower and pronounced

2.Noise seems to be coming from the limbs vibration, not so much an instantaneous loudness. I think its the vibration drone I hear

3.There is currently nothing on the bow except for wool puff string silencers

thanks for the comments so far!

string to nock tension ?

also did you weigh the arrow ? carbon is lite , unless weight is added. Unaltered they tend to come in with point about 425g

string to nock tension; mine is really loose actualy, more loose than i would expect it to be.

did not weigh, but 10.5gpi at 31" plus 50 gr inserts and 200 gr tips should come in around 600 i think..

thanks

im measuring BH from string to throat of grip. I just read some measure to back of arrow shelf? I thought is was the deep part of the grip.. Maybe my BH is lower than I thought?

Brace height, usually best to look up in your manual or contact bowyer. If they are not in business: someone on here will know. Seems like fdp is familiar with the brand and George Stout has handled a lot of bows. I tend to gravitate to one area and stay there with manafacturers.

A lot do from throat of grip but if the bowyer does use a different point then you're obviously going to be off.

IMO brace height seems most logically measured from the high point of the shelf or other rest, whether per-design or per-modification (e.g. the famous match-under-rug). Hard to measure from anywhere on the grip.

AMO is and always has been to the deepest part of the grip. You can measure it from where you like of course, but that's what most bowyers/manufacturers go by.

AMO STRING HEIGHT STANDARD String, or brace, height is the perpendicular distance from the bow string to the Pivot Point of the bow handle (low point on the handle just below the arrow shelf, see nomenclature sketch, p.15) when bow is in strung condition.

I bet a few more twists in the string will quiet it down.

George is right (as usual). The way you describe the noise it sounds to me like a combination of low brace height, bad release and string silencers that need to be moved around to where they work.

Brace height is VERY individual, and you have to find a spot that works for YOU. I now a really well known bowyer that shoots his bows well below the brace height he suggests, simply because that's where it works for him.

Twist up the string and pad the area below the loops like PD said. You'll quiet it down.

Try the "heterodyning" string silencer placement. 1/4 of the string length (contact point to contact point) and 1/3 from the bottom.

Gets quick repeatable results to at least quiet the string.

I had a long scientific thread a while back....sometimes your limbs are a resonant frequency with the pitch that your string and is making. That can make that oscillating vibration you describe.

If it's vibration it's the bow. If it's from the string it's oscillation. Here's how you get rid of oscillation - well you don't get rid of it my make it smaller. This may be my hunting bow this year - it's quiet.

thanks for the suggetions!

any thoughts on different string materials or types to try

ben

You should be able to get the bow quite no matter what string material you have on it. And it doesn't matter whether it's endless or Flemish.

i have gone up to 8.75 brace, vibration on riser seems the same to me

thanks fdp... not sure why the thicker atring i have seems worse than the rhinner string... maybe thats in my head....

Is your bow a 3 piece ?

it is a one piece.

i bought it used off of archerytalk so no manual or anything...

Try 9" brace - I'm playing with one and I had to go to 9 1/4" to quiet it

flinger, you are at 9.25" with a dale dye?

I reached out to the previous owner and he said he was having good results at 7.5 with cedars..

I need to keep tinkering I guess.

thanks for the replies!

Ben

Not a Dale dye - mines a trad tech titan - don't see where you said it was any brand - till now ??

String material makes a huge difference in vibration. I can put a B50 string on my long bow and it has very noticeable vibration. When I replace ir with a Ultra Cam skinny string the vibration is completely eliminated.

hey flinger, first post.. thanks man!

865 grains!!! hoy smokes, im a lightweight in comparison. i reached out to original pwner he was shooting cedars. are they typically heavier?

ultra cam skinny string, what is that? maybe i should look into a diff string?

Ultra Cam is an excellent string material, however it is no longer made. Rino is a good replacement. My skinny string is made with 9 strands of Ultra Cam which makes a very thin string with the loops padded to 18 strands. A skinney string increases the performance of the bow. I usually have to go up in spine about 10# when I change to a skinny string made with low stretch material

George is right about AMO (Archery Manufacturers) definition of Brace Height, HOWEVER that is a flaky way to measure as it doesn't address the two absolutes: string and point of arrow contact on shelf or rest.

It's probably good to use standard terminology, per George, even though the "manufacturer's" terminology isn't as helpful as it could be. And it's not as goofy as "fistmele," which I learned about 50 years ago, and which means nothing...given that human hands differ tremendously.

I'd give Dale a call. I bet he can give you a easy fix.

Just curious how much do your arrows weigh?

did not weigh, but 10.5gpi at 31" plus 50 gr inserts and 200 gr tips should come in around 600 i think
