I got a couple new strings made for my Safari , I twisted up the new string to match the one removed , set up for 3-4 days and checked brace , 3" stretch . I did pull it back at least twice daily . So tonight I twist it some more to match existing strings length , and check brace and string legth, bang its 1.5 inch longer just from being strung . Brace is now 6.25" . don't remember what it was with old string but it shot great. next the strings came with all the frays sticking out and un-waxed . should I have burned them or melted them back ? Last time I used b50 it was 1980ish, just got me confused .

Well....my opinion is that you don't get a string settles until you shoot it number one. Maybe you did, and just didn't say that.

The strands sticking out make -0- difference if the string is well made to begin with. I've left them long on purpose to act as silencers.

It should be good after 50 or so shots max. Was the string stretched before you got it?

A lot of factors can come into play here. First, how well the string was made to the length needed. How many twists were needed when it was first constructed in order to reach the desired length. How tight were the twists? Second, it will tske some shooting for a string to stop stretching. Finally, remember your proper beace height and keep an eye on the stretching. It is possible the string is failing. But, most likely it just has a lot of stretch in it. It does seem to have a lot though.

pre-stretched, I don't think it was . and no shots yet.

Start shooting it, that will get it to settle quicker. Crank it up where it needs to be and shoot. Now, just to be safe, you aren't twisting it the wrong way when you started shortening it are you? I think we've all done that.

B-50 stretches a lot but the stretch you are experiencing seems excessive. It sounds like you might need to twist up another sting and start an inch or two shorter. Take care to build the loops carefully to help reduce stretch. Pre-stretching during the build will help too. Twist it ten to fifteen turns under tension too. That will help. Good luck. Keep at it.

I followed the twists it already had , String was made by bowyer , Byron F's actual bow shop in Al . I called them about the bow and asked a few ? then I asked for two strings to match the bow they built , most likely the string just needs some shooting , . I will put a few shoot through it tomorrow. I should have asked them whats the correct brace for it though.

hmmmm....3" seems excessive to me. Back when I twisted up b50 strings, I'd hang 70# of weight plates on it overnight, or even a full day. No 'settling in' at all doing that. Set brace and it stayed there. No movement at all. b50 is good string material. #55 bow btw.

I do something similar to what Bb said. the last string I made only really stretched a couple inches total and that was with heavy shooting after a day with 50 dumbbells hanging from it. For whatever reason I had one string that I thought was going to never quit stretching. It finally settled but it was a weeks worth of frustration. I know for sure 3" would not even start the amount of creep that thing went through.

that's not stretch, its creep. The string was made too loosely and tightened that much. One good argument for endless strings. A bowstring should be made so that it reaches it's length with 100lb weight attached for heavier strings and 50lb weight for lighter strings. B-50 will stretch about 3/4" over a years time if the bows left strung. If the bows unstrung when not being used it'll stretch about 1/2" because it draws back each time the weights taken from it. You got a poorly made string guy. Thes companys make them to look good but don't worry about precision when it comes to length. It may be pretty but its not made to reach its length only while under a weight load. I used to shoot 73-76 lbs and now shoot 62lbs. My strings and even the ones I've bought had no tightening to do when first strung and only stretched between half and 3/4"

When you buy a Flemish string if its not made uner weight its gona tighten and no two guys make them tighten the same so ur gonna get some you can twist a couple times and some that will look like a rope it's twisted so much. You don't have that problem with endless loop strings but most like the looks of Flemish. On the bright side there are a few larger companys now using the weights and selling consistant strings. Bow weight should make no difference if the string is the right number of strands.

Soak the string in hot beeswax then immediately string up and rub. No stretch after what and it really protects as all strands are coated. I use a little potpourri crock pot. Swinehart used his oven after rubbing heavily.

There is no way a string should stretch 4 1/2 inches. Dacron will stretch quite a bit by nature but 4 1/2" is incredible.

Anything more than an inch indicates a very poorly made string.

Agree with GLF and 60X. Dacron will stabilize pretty quickly if made properly. That isn't stretch, it is creep as GLF said. I can make an endless loop Dacron and it maybe will stretch up to 3/8th inch at most, usually not that much. You can account for that before you make it.

George is correct.

Creep is permanent elongation of the string. Stretch is temporary elongation in pulling the string and shooting, but returns to original length afterwards....like what a rubber band does.

The problem your experiencing is due to design and build, and I concur with the others in that you shouldn't be experiencing that much creep in any build or material.

How many strands is this string?

OK, I'm going to word this to eliminate the confusion between creep & stretch.

It is highly likely your string was either poorly load conditioned during construction, OR not load conditioned at all.

Dacron materials yields "A Lot" of initial permanent elongation.

3" is not an uncommon amount of permanent elongation at all. When I build strings from Dacron, I generally get quite a bit more than that from them during the construction, and load conditioning.

If they are properly constructed, and load conditioned during that construction, they won't elongate much more if any at all when placed into use.

Here is two pics, they are both 16 strands,

wow that's not mine,

and the strings seem loose ,I had to twist the heck out of them to fit brace h

oh and to hoom took the shots , nice group

it looks like one bundle is twisted more then the other.

I have to agree with George Rick. I've never gotten more than 1/2 to 3/4" on any Dacron string. It may not be creep but its the string tightening up. You don't get that on endless loop strings like you do Flemish.

"If they are properly constructed, and load conditioned during that construction, they won't elongate much more if any at all when placed into use.

Rick"

Ok , gotcha Rick.

Its the Flemish string tightening up Holezone. Try a proper made endless and you'll see. When you used to buy a new bow it came with an endless string. Once strung it would stretch 1/2 to 3/4 ".

does D97 stretch enough to be safe for 10yr old longbow with no re-enforcement to tips ? It cam with what may have been d97,

lmao, Holezone, nice fix!

You still have to watch who's making your string. I just sent back a d97 bought to replace the string that came with my phenolic bear sk. it tightened up 2 inches when put on the bow and I don't like strings twisted so much they look like a rope. You could see it was very loosely made tho. The d97 that came with the bow didn't tighten at all, it had been made under weight as it should have been. But they made it too short,lol. It gives me 9 1/2 inch brace.

Just an FYI, all the folks that market string material have technical specification sheets. I nearly all instances they suggest how many twists per inch should be put in a string.

May want to take a look at it. I know that Rick, and the other guys that build a lot of strings are familiar with it. Even an endless string should have a certain number of twists in it. If they don't, then when the string is released, the string fibers want to open up and act like a tiny parachute.

Getting the string constructed properly, with the right conditioning, and the proper amount of twists is why strings aren't cheap.

thanks all , it did finely near stop. Just got a herters 70" longbow with inlays at the tips, had no string. The inlays seem thin , what would be a good string for said bow ? Its 57# @28" . Would you use d-97 as many suggest for this older Herters ? thanks again Randy

Randy, Is it the Itasca model? I personally would use a padded loop low stretch string, perhaps a BCY-X around 14 or 16 strand. The D-97 will work fine as well but I've found it harder to quiet than others. And you can always use B-50 if you like, but you will get more thump out of it on that bow.

Rather than "thump" I would categorize it as more vibration. A well made B-50 shouldn't stretch more than 3/8 to 1/2 inch in my opinion.

yes George, Itasca, Waseca, Minnesota.

See Rick Barbee's comments about Dacron, above.

Yes...properly made, and many are not.

Randy, check this out for what tip overlays should be on those.
