I am having problems with my center serving just below the nocking point. The serving tends to twist and move. Sometimes it works loose and even doubles over on it self. It gets to the point that it slides down and bunches up. I can move it back and shoot a few more arrows and its back to the same problem again. I tried to have a bow string made by someone else and it did it on that string as well, however it took more arrows before it happen.
If I had shot thousands or even hundreds of arrows I could accept it. But it does this even after 50 or 60 arrows. I have tried different tensions on my serving jig. I have been told that my center serving is wound to tight but when I try looser the problem gets worse. I have also tried different sizes of nocking points. I was wondering if maybe the twist of the bow string might have something to do with it or maybe the size of serving. Maybe the arrow nocks are too tight on the string, however I do not think they are. It would be greatly appreciated if anyone has any ideas how to fix this problem. I would like to continue making my own strings but I need to fix this problem.
Talk to Hutch on here. He makes strings so knows all about this stuff. My guess is that you're not serving tight enough. I know when I redo mine I have to hold the string close to where I'm serving to keep it from twisting as I go. Basically, tight as a bulls azz. The only problems I ever encounter is a slight serving separation right under the arrow nock, aout one thread width, but I use a rope release so this creates a very sharp bend at that point. I have only ever used older braided fastflight and rarely have any problems with it kinking, doubling over itself or anything else, and only use about a 4" center serving.
Barry nailed it right on the head too loose. Questions for you what type of center serving are you using? Are you serving it with the twist in the string?
Put the bottom of the bow to your left serve it towards the right (to the top of the bow). Serve it with the serving tool towards you. Snug it tight enough that the serving tool will not move freely but not so the string twist.
