string stretching?

[Zach Mikita]

Why is my b50 string not keeping the brace height on my bow?

[lpcjon2]

Is it a new string? it could take up to 50-75 shots to stretch. Or it could be unraveling if its a flemish string that was not made correctly.How bad is it creeping.

[L82HUNT]

How many strands and bow weight, how old?

If it is a new string it could take a couple hundred shots to get it to settle. If it is an old string, then i would quit shooting it and get a new one.

How old is the string? If it is new you should let it sit on the bow strung overnight and that should take most if not all of the stretch out of the string.

brand new string on a 55# @ 28 I wondered if it needed a good break-in period.  I have been shooting all week so Ive had atleast 100 arrows through it.  This help?

B-50 dacron is notorious for stretching in a new bowstring. It's going to take more than 100 shots.

With the bow strung, place the back of the bow on a carpeted floor and press the limb tips by hand to "hand stretch" the string. I do this to the strings I make (flemish twist) and my break in time is nearly zero.

It only takes about five minutes of stretch and relax to get it stretched to a good settle point.

After that I have minimal adjustment to get a consistent brace.

I hang all newly made B-50 strings from a hook overnight with a 60# dumbbell on the end. Keep the dumbbell from rotating.

I even do this prestretching with D97 strings.

Several 100 arrows for B50 to settle in, maybe even more if it's a flemish twist.  Just a matter of checking and adding an occasional twist or two every shooting session for awhile.  It'll settle down eventually; when depends on the type of string, number of strands, bow weight etc.

Nature of the beast.

Yeah and when you get gett'er all stretched in then go and shoot when it's good and hot outside, you'll probably have to twist'er up a bit more.

What Bud said!

[David Mitchell]

I absolutely have no problem with string stretch on my B50 strings.  I do exactly as Bud B said and have no further need to adjust.  I don't know what you guys are doing wrong who have all this trouble with B50.

With a new string I string bow up about half an inch higher then what my brace hight should be and set the bow on the rack.

 Let it set all day and every now and then when I walk by I will pull the string to my ear 4-5 times. And maybe go out and shoot it also. A day or 2 and string is good to go.

Yes this!  A new B-50 string will stretch like a rubber band when you do this, and you'll then understand why it takes so much shooting to settle one down.  Using this method they stabilize much, much faster.  I often lay the bow across my lap instead though, since my bows usually have a bow quiver on them.  You can get more pressure on them using the floor as Bud described though.

Thanks guys!
