[video=youtube;utkjloGPoFs]http://www.youtube.com/watch?v=utkjloGPoFs[/video] and i had the good intention of making a video of my whole stringing processe. timed and everything. and it just had to die like that. that's ZM62 for ya. it's the price to pay for such a sweet string. the tension was 27lbs.
and as you can see my reaction, it was like "oh crap." "what do i do now?" "nothing, restart from scratch."
I have strung ZM62 (or more or less my stringer although I was beside him all the way assisting him and chatting) at 28lbs constant pull tension at least twice now and have yet seen it snap just like that. Check your double pass grommets, perhaps there is a sharp tear in it or around the grommets' neck.
The feeling will be more horrible if that happened while you're stringing the cross (and you're done with the main) =.="
The moment of disbelief. Then the slapping of the thigh. Classic (sad but hilarious) Good self-control not to be caught cursing on tape.
Now imagine that happening two crosses from the end, which befell me while I was stringing a customer's Ultra 1 a while back. I recall very well that moment of utter bemusement before the inevitable realization - "back to the beginning... FFFFFFFUUUUUUUUUUU!!!" It was also Z62, by the way.
Hi Kwun and ppl Take it easy!! It happened to me sometimes. As we say here it only doesnt happen to those who do nothing (i am translating the proverb directely as we say it here). Sometimes the work goes down the toilet in the last crosses because of the snapping or then because of serious accidental damage made by the hook applied to create the path in single grommet systems (I hate to restring yonex NS9000 because of the last top cross). Damaged grommets many times have the fault for the situation you showed us. It is time to a deep breath and get few minutes away from that room.
luckily i only wasted 10mins of work (at least according to the recording) this is the first time this happens to me. in fact, first time ever a string snaps on stringing, Covina is right, Murphy's law! i will try again tonight.
the 2nd attempt is much better. strung a AT700 beginning to end in 26mins. the video is huge. i will chop it and post it to youtube tomorrow. comparing my video to AK's video. i feel i am so slow.
Twenty-six minutes! I spend that amount of time during any given stringing just on fiddling with the CD player, getting snacks, and being interrupted by children with burning questions about Star Wars and fairy princesses.
kwun I just noticed that you were pulling the 10th main string after the 9th rather than going from B9 to B12 and pulling the 11th main, then finishing with the 10th main string, as according to the Yonex recommended/official pattern
yes. but unfortunately, my machine only have flying clamps and not possible (AFAIK) to do the Yonex pattern...
welcome to the club. wait till you try to string older rackets with high tension. Nightmare. There's gonna be lots of fffffffffff....
It is if you go up 12, back down to 10 and pull from there, don't know how bad it is for the frame or tension loss but i figure i don't hit out there very often and they're pretty short strings by then. I normally clamp 11 to 12 and 10 to 11 to be sure, then repull.
I have made a promise to myself that I will not buy any more rackets which have all shared holes in the corners. For the ones I have right now I will only string with zm62 to make it easier. I tend to string in about 35 minutes for others and about 25 minutes for myself as I tend to take a bit more care for other peoples rackets than my own. The only time I've broken a string during stringing though was right at the end, pulled to hard on the knot and the string broke and the knot slipped out. Had to pull the string out and have 1 less cross, no big deal.
Correct, and for tension loss problems the only way to negate it in this case is to put a few more pounds on top of the intended tension on the 10th main when you pull and wait for it to stabilise for a longer time than usual. The six point support should prevent the frame from snapping apart.
sure. if i skip tensioning the 11th main and pull the 10th only. but what do i gain from doing that? just to comply with the Yonex pattern? is there a big enough advantage in the Yonex pattern for me to forgo pulling one string?
