I just made a continuous loop string for my grandsons new bow. First time I braced it the serving pulled apart(arrow). I've made a half dozen or so CL strings and this it the first time it's happened. I'm not sure what happened. The bow is only about 20# so the tension can't be that high. What did I do wrong?
PS this is on the non overlap end, if you know what I mean.

Looks like it's rubbing on that bottom edge maybe. I would narrow towards the belly side so the loop slides easily along that edge. There is plenty of "meat" on the tips so you could narrow then, at least towards the belly.
-
Your bow tip shape is more the culprit.
-
It's not quite a square as it looks. That "corner" is mostly shadow but I can see what you're saying. I will round it off. Should the tip be circular in cross section? I'm still tillering, that's why it's rough.
-
Just make some nice grooves merging at the shape of a teardrop. Then there is no force splitting the served area.
-
I think the groove in the horn does not line up with the groove in the wood

Can I bring this up again. I'm still having this problem with continuous loop strings. The serving separates and pulls apart. I've tried reshaping the tip with no luck. I'm wondering if my loops are too small. I like a small loop on the bottom so the string doesn't fall off but it seems like it's stretching the serving. Could I get someone to post a picture of a continuous string loop on the bow so I can get an idea of how big the loops are and kind of the angle it lays at?

I think maybe you are right, I dont have a photo,, (-S

This is a known problem with continuous loop string, especially on warbows :o I'll share my findings.
1. Have plenty of tension on the string and serving material while serving.
2. When pulling the two ends of the loop together (where it makes a Y) start the serving with some figure 8 holding the two together, and overlap slightly over the loop serving. That works quite well, but can still pull apart with V high tension warbows.
3. What I've been doing recently is to bind the two sides together with some very fine linen thread (just 3 or 4 turns) and the touch it with low visc' super glue. Then serve over that. This seems good and reliable, the superglue doesn't adversely effect the serving or the string as it is both manmade and waxed ( I wouldn't recommend it with a natural string)... but it does soak into the linen forming a solid ring which clinches the two sides together.

PS.. .don't tell the other... it's a secret ;D

Thanks Del, mums the word.

Not enough tension on server as Del stated and you could reduce that tip diameter and round it over some.

Thanks I'll try that.
