Title: String Twisting Question
Post by: mrpenguin on March 31, 2010, 10:01:00 AM
Quick question on string making... if a string is made a bit too long and it is twisted up quite a bit to get to brace height, will that effect how the bow shoots?  Basically, will an excessively twisted string effect windage?

Thanks guys!

This will be interesting to see what different string makers say. I have been making all types of strings for 20+ years and when they come out a little long I just twist them up more. Now if the string starts to knot up thats where problems start. I have seen no difference in arrow flight as long as brace height and nock point are correct. Others may have a different answers.

Yes. I believe too much twist makes a difference in the performance of a bow! If your not sure, try it, make one up a little longer, and shoot it, you will feel it in the shot. Vibration and side to side ocilation, you bet.

Last summer, I shot a very fine made selfbow, beautiful tiller, great early draw tension, and the shot, horrible. Just shouldn't be. I looked the string over, unstrung, and unwound a portion, way too much twist.

Think of it this way, if your twisting it up alot, your using more material, = more unwanted string weight. This is the trick of doing good flemish strings! And why some prefer to do only endless.

Terry Green said on a post awhile back, to Jerry Hill about a dacron and High performance string shootin about on Par as for speed. After reading I wondered if the HP string was built with too much twist, probably.

For the folks who build their own, and complain of too much creep, probably too much twist!

Now, not saying you can't shoot with it, you can, and you will adjust to the cast and performance, but it could be awhole lot better!

Another thing I have seen from folks who give you a string measurement, say 55" and you make to the specs, but they say it came up short. If the string they measured off of had too much twist, and when braced, will stretch considerably more, so the big difference in length. My 25+ years of twisting, experience.

Thanks gents...

I think its time to twist up another string and see if I can get that bow to tune up better.  She shot well before I made the string... I though it was BH and arrow tuning... I will post back with my results for others to know : )

I do recall someone saying a string that is twisted to much can damage the string itself.

I don't think it will damage the bow or string.But I feel excessive twisting can make a strind act like a coil spring even if it is made with low stretch string materials.I feel it can effect performance.JMO

As a string maker, I cut all of my flemish strings so that (when twisted up)it takes me an additional fifteen twists to marry the strands together at my desired length (under pressure). If it takes more than forty twists to get your desired brace height after shooting the string in, you need to order a shorter length.

At least that is what works for me as a string maker.

Just wondering what most think would be the right amount of twist (10-15-20-25-?,and be at the right brace height,

I'm with DesertDude, if it starts to knot up - yes.  I've never noticed any difference in the bow.  H

Exactly what Frank said. Too many twists cushions and spoils the string.

Ideally a string would have no twists.  But it would have to be an endless loop...Van
