    Default HELP! Keep snapping string at the same spot

    Hey guys, please please help. I have a tournament coming up on Sunday and over the past 3 days I've snapped the string of this racket 3 times in the exact same spot.

    Picture is attached. I do my own stringing and have just recently started doing so. I string at 26 x 28 and can get about 2 hours of play and then SNAP!

    what string do you use and check the grommets?

    bg85 and yes, just replaced the grommets on both my z-slashes...

    One of the other players here told me that it could be from my stringing method. I follow the Yonex method, centre-out. Could there be something with the tension aspect?

    I usually use a fixed clamp to lock down one side while I string a1 through a3 on the other, then switch sides and continue the pattern.

    edit: I've never had this problem when I was getting my rackets strung, it's recently since I've started doing my own :/

    The ends of the broken string are almost exactly equal in length - this is highly suggestive that the string snapped at the frame. This being the case, there may be something (a bad grommet, a bit of rough paint, &c) where the string interacts with the frame.
    I can't see it being down to stringing technique as such, as bad technique wouldn't be so discriminating in choosing that point on the stringbed.

    If we were looking at a mis-hit one end of the busted string would be a good inch longer than the other - it's a dead giveaway when somebody clouts one off the top of the middle mains.

    Hmmm...see, I thought the same thing, but I replaced the grommets earlier today and it still snapped. I inspected the frame quite well. It's funny cuz I strung a racket for a friend too, at900t and his snapped EXACTLY the same spot.

    Thanks for the thoughts....

    That's made things more interesting... maybe something's happening when you clamp that particular string (but we've no way if knowing what that might be).

    I wonder if the clamp itself is too tight? A friend suggested that perhaps the tension on those particular strings may not be equal and thus creating some sort of weird tugging or pulling effect at the grommet...

    Yeh - the clamps should only be the minimum tightness necessary to keep the string from slipping out.

    When you start a racket do you clamp one side untensioned to pull the first main? If so, try pulling both mains at once and then lock one side off, then proceed as normal. This gets some tension inside the first clamp; if you clamp an untensioned string, the zero inside the clamp will "jump out" when the clamp is released and contaminate both centre mains.

    Also, if you use a crank machine you should release the first clamp while pulling; if you pull then unclamp the same thing will happen: you'll get 26 before unclamping and then lose some when the lower tension from the double-pull jumps out.

    That may be the issue. I'll have to try later and test the racquet out quickly before the tourney.

    BTW, I use an ECP machine

    From the post above mine, came across these nifty little things. I may try them.

    Then nothing I mentioned should be an issue:P - if you leave the puller for an extra couple of seconds it will take out the zero for you.

    The string protectors - best place to try is mybadmintonstore.com (I think they still carry them...).

    Damn it all, after a few successful string jobs on a few different racquets, the problem has come back...could it be a bad batch of strings plus improper technique?

    I need to find a local stringer who does it well and see what they say

    sigh

    Your gripper may be squeezing too hard, damaging the string. Try putting a folded index card slightly longer than the gripper, if you are using a linear gripper.

    What kind of ECP are you using?

    I highly doubt that it's a bad batch of strings / stringing technique / clamps

    That breakage still looks like its from a bad grommet

    Did u have a look at the grommet and the hole before you replaced it?

    What grommets are you using?

    I just don't think that a string can break at the same spot if it's a bad batch of strings / stringing technique / clamps.

    Wouldn't hurt trying those protectors out

    I'm using the 2086's gripper plates and I use a business card in between them for a better grip. I've adjusted the clamps grip to the minimum required pressure in holding the string.

    The grommets should not be the issue as this has happened on 6 different racquets...

    What about the pre-stretch option? I may turn it off and see what happens, the two racquets that Im using that are still fine, if I recall correctly, were done without the pre-stretch...

    The pre-stretch is probably damaging the string. How much do you have set, 5%? You really don't need pre-stretch because of the CP. Pre-stretch is good for syn gut and not really multi-filament string like most Badminton strings. Try stringing it without pre-stretch and see if still breaks in the same place.

    The cause for the string breakage is simply one of miss hit. The racket you have has the non-standard 21 cross string pattern, which is one less than the standard. This results in an area at the top of the frame that has a larger area that is not 'protected' by the crosses, hence it is more vulnerable to breakage from miss hits. Any large portion of the string bed that has no crosses at the top is vulnerable.
    I suggest you develop a more focussed hitting style, one that relaxes at the back swing and then snaps at the forward swing. This will give your shot more precision and also more focus.
