string vibration

[masterj]

I am shooting a Samick Journey #40 @28. Brace height is supposed to be 7 1/4-8 1/4. It was Approx. 6 1/2. I put a few twists on the string 6-7 total. Now the string vibrates like a low frequency tuning fork after a shot. Is this common?

[Stumpkiller]

Yes.  Add some wool puffs or other silencers.

[Moots]

I wonder if you need to twist the string even more to get to the proper brace height and quiet the bow.

[masterj]

Stumpkiller, thanks for the reply,I am only target shooting, don't intend to hunt. If this is normal, I can put up with it. Moots, I was wondering the same thing. This is my first bow, only shooting a month, so I hesitated putting too many twists in.

Welcome to TradGang.        There are a few ways to silence the string. If you have a Flemish twist string, the easiest way (to me at least) is to wrap some yarn around a credit card and slip it in between the strands. Bunch it up, trim the strays and you're good to go. The "How To" section has a few write ups.

Two Tracks (sponsor here) has some pretty neat looking wool silencer that slip into a Flemish string as well. For an endless loop string, I'd get some cat whiskers and tiny zip-ties.

Edit: I'd try to get the brace height to what the manufacturer recommends first. Twisting the string up shouldn't hurt anything unless you go crazy. Are you shooting the string the bow came with?

Target shooting ..or hunting... I LUV a QUIET bow. I think Mr Green might have a solution to your problem....Lloyd

Whats wrong with turning it back down to 6 1/2 in. All bows are a bit different and you don't fix what ain't broke.

God bless, Steve

The "stock" string that comes with the Sage is usually not the greatest.  Good bows, they really come alive with a good string.  I suggest 18-20 strands of BCY-X, 12-14 strands of 8125, or 12 strands of Dynaflight '97.

What LBR say's, and then string her up at 7 3/4 brace height, tie on some cat whiskers 10" for the top and 15" for the bottom, measure from end of string loops to center of silencer. betcha it shoots great and no noise or vibration

I agree with a good string, I've read many posts on the stock string that comes with the Sage to be adequate at best.  

That said, don't be afraid to twist it up, it should settle down eventually.  Just keep twisting until it's in the recommended range.  Watch it as it settles, it might get a little longer again and brace will drop...just add a few more twists.  I've had new strings that need 20 or more twists before the brace was right and every thing was settled in.  

Most recurves I've had are quietest at the high end or even a tough over the high end of the recommended range.  If you want to quiet it down even further, a combination of string silencers and yarn on the string works great.

As others have said a good string and proper brace height will really calm that bow down and you will enjoy shooting it alot more not to mention it will be more forgiving as well.

Are you measuring the brace height correctly?

hi fellows.. along the same line, I have been shooting since I was a kid (I'm 64 now) and in the past week, heard two things I'd never heard before regarding bow quietness and shootability..  first, I heard it suggested that you place a strip of felt-side velcro where the string contacts the limbs on a recurve - so the string is cushioned on the pad..  wonder if anyone does this, and the advantages/disadvantages?  Also, I heard that you should NOT use the crimp on metal nocking markers (but it did not say "how come").  any imput on the possible reason?

[Bladepeek]

I never used the stick on pads, but I did put Bow Hush on all my recurve strings. It's wool yarn wrapped on the string where it contacts the bow limb. Look it up on the sponsors list. Really seemed to help quiet my 'curves.

I don't like the brass crimp-on nock points because I usually manage to get some sharp burrs on them crimping them on and it cuts my glove. I sometimes use them on a new string because they are fast to put on. Once I find the correct location, I usually remove them and tie on a finger friendly nock point - two actually. I like one above and below my nock. On the plus side of the crimp-ons, I can see and feel them much easier in semi-darkness than my tied-on nock points. I was shooting on one of those techno screens and the room was really dark. Had a bit of trouble getting an arrow nocked quickly with the small nock points I had tied on. I shot my buddy's bow and he had brass crimped on and it was really quick to find.

Lot of personal preference involved I guess.

[Frank R. Brown]

Thanks Bladepeek for the comments - I think you summed it up with "personal preferences" -  interesting to me how many variations on a theme you can get with something a simple as a traditional bow!  Hope it is not too cold up there in Michigan..  been a cold winter down here in Texas so far.

[LBR]

Personal preferance sums it up.  I've never damaged a glove or tab with a brass nockset, but I only use one specific kind of nock pliers that won't leave any kind of burr.  Sometimes I used tied-on nocksets just for a change of pace.

I've seen bows with velcro, but haven't tried it.  I mostly shoot longbows anyway.

[masterj]

Thanks guys for all the suggestions, I have been playing with the BH and am getting some results. Frank R. Brown, this is the 6th coldest January on record. If we get another 10th inch of snow tonight or tomorrow, and they are predicting it, it will go done in history as the snowiest month ever in SE Michigan.

X 2 on this post.... Hey Keith, What did you think of that offset silencer location 10" & 15" vs 15" & 20" ?  Still work ok for you?

[reddogge]

Frank, those soft stick on pads on the recurves had a tendency to bunch up or slide askew in hot weather so I've taken to wrap the string ends with wool yarn down to where they contact the recurves.

[Keith Langford]

Worked great Kirk, I think as long as you leave that 5" split and cancel out the odd and even nodes it's good, I am going to try 8 and 13 and see how that works
