I always get this annoying twist in my loops with endless strings, I suspect it might be due to my string jig not being tight enough when I do the first servings before I serve the loops together. Anybody know why and maybe how I can fix this?

I think the serving jig does that to mine...After stringing and a few shoots they seem to disappear though.
That's just a good sign of some tight serving, good job...
-
Untwist them ::) ;) ;D >:D you might have to get the server to loosen up a bit. You want it tight but too tight gets that
-
It's because you are introducing some twist in the string as you wind the string off your spool and onto the jig.
You can see this in a more dramatic form if you wind anything like an extension cord or a hose up. The loops will tend to try to figure eight.

Hmm, okee dokey. So I should probably serve the string a bit looser?

Ive seen plenty of purchased EL strings that had that twist. It might be slightly inherent to the style?

Thanks! I love when it's an easy fix, :), thank you!

I sure wouldn't serve it looser. You don't want it sliding around. Your serving job in that picture looks excellent. Are you twisting the string on your jig before you add the final serving layer?
I think its time I change my signature line ::)
-
Ah. That's better
-
Well either way I will try doing the first serving just not "as tight", maybe "looser" was a bad word choice. :)
-
I wouldn't change a thing... Keep it tight! Are the twists causing a problem? When I make endless loop strings and use a jig it twists every time. The cover serving is what causes mine. As the spooled jig passes each string a slight amount of twist goes in each one. when I take it off the jig the loop tries to reverse twist. But as I said before it always comes out later. I'd rather stay on the tight side...
If you look closely you can see the strings under the cover serving already beginning to twist caused from the friction of the serving spool jig.

I have had endless strings that were made with too loose of serving snap on me at the string loop while shooting because the serving shifted and the strands beneath frayed quickly. Keep it tight.

Hahaha. No offense to the well intentioned 14 year olds out there but this is so true.
-
I've been through a lot of old endless loop strings in my day and the problem is typical in all of them. Just to double check I pulled out an extra string made by Nirk (old) for an old 60" Bear B Mag and it's twisted just like yours.
-
I do the second serving that closes the loops with the string under around 150 lb tension, so it doesn't twist when I do that one. It does twist the string a bit when I do the first servings. I am figuring this is where it is happening. I wish I could think of a jig that could tension the string enough for it not to twist for the first serving, like something with springs or something... Well I guess you guys don't seem to mind, maybe I should just join the club... ;D

Does the mere thought of a bowstring out in the garage with that twist keep you up at night, Dr. Sheldon Cooper? If that is the case, I could show you a photo of a shoebox of unsorted extra bowstrings that is positively a KNOTTED MESS that would leave you unable to eat spaghetti for the rest of your life.

Not trying to beat this post to death...Here's a few pics of what's going on due to the string jig twisting the string on every pass it makes around. It's what happens upon reverse twisting...

Oh the horror! :)

The reason for that kink has now been explained three times correctly. ;)

Haha, yeah, you would figure a normal person would be able to figure these things out on their own. You wanna see something real funny, you should watch me try to figure out whats wrong with my van, :).

He told me he has it narrowed down to the 8-track player or else the shag carpeting.

My advice is ........ it doesn't matter one bit and it's much better for the string to be like that than not in my eyes. Tight serving on these strings is a must.
-

Absolutely NOT! If you serve it 'looser' the serving will migrate all over the place, leaving gaps of bare string in the loop. Obviously, this is not good. 90% of the commercially made endless loop strings I've purchased for recurves have a twist in the loop. It usually disappears under tension when the bow is braced.
-
i thought the idea WAS to have twists...my head is beginning to hurt. lol
-
I used to make a lot of endless loops, and don't recall every having a problem with twist. I notice that my loops were much smaller than the ones you're making, so that might be why.

I have maybe 50 E.L. under my belt and alot are like that. Some have well over a thousand shots and I havent had any problems.
