One of my last bows has a noisy string, it makes a vibrating sound for an entire second after the shot is made. What could be the cause? I did make the string a lit long, so I twisted it to shorten its length more than normal I dont know, may thats it.
-
Is it a recurved bow? I had one that had the string running parallel to the bow for an inch or two, just barely touching. It would buzz and vibrate something awful. Changing the brace height a bit solved it.
-
Only ever had that problem if it was an FG bow using an endless loop string. Or the tiller is way out of whack.
-
No not a recurve, I will mess with the brace height it does look a little high. I think the tiller is alright but I haven't put a finish on so I can tweek it it if I need too. I definitely don't like the noise.

Pics help
-
A pic of the vibrating string or the crappy tiller? ;D
-
It has to be the tiller.
-
I like to out in strips of fir right under the Flemish splice. What kind of string material did you use?
-
Fast flight string, I think the tiller needs work. What I am seeing in the photo, top limb looks too weak, but the outer top limb looks stiff. It kind of looks like the arrow is traveling down in the draw also.
-
Tiller ain't bad. What grain weight is the arrow, how heavy is the bow? Your limb timing may be off as well. For fun, flip the bow upside down and see if any difference can be had.
-
Arrows are 460- 500 grain, bow is 40 lbs. Top limb is longer than bottom limb.
-
Just put fur silencers on the string. They work wonders.
-
Yes they do I just put one on the top limb and it worked great.

Got to agree with Jeffp51! Even Ol' Glassy One looks better and is quieter in beaver! >:D (lol)

I've never noticed a bows tiller contributing to noise. Its usually because a string isn't round or its cabled up. A bow string is like a guitar string, there are harmonics involved. Glad you got it quieted down.
-
I realise that the fluff ball solved it but just as a curiosity did you try changing the brace height? Since it's a straight bow and the string can't vibrate against anything it pretty much has to be harmonics. I know nothing about that except that the string tension and length contribute to the noise. Maybe a guitar player can help. You really can't change the string tension that much(I don't think) but BH will change the length a tiny bit. Would it be enough or would it just raise or lower the pitch? I'm not a big fan of fluff balls although they work great. I have used a 2" piece of brain tan (thanks BowEd, where is he?) lace just wrapped in the string and it works and is less obtrusive but I would rather have nothing.

I had never used a silencer before so I didn't think of it until you guys mentioned it. I did lower the brace height and I think it helped a tiny bit. Man the amount of things to fiddle with on a bow, sure keeps me thinking.
