    I have broken all my 3 Nano rackets (9K,8K,7K) during stringing in one Month. They all broke in 3/9 O'clock and they all happened when I strung the final main string in one side. I used a crank stringing machine (6 points) and 25lb for the main string. And also I have 50+ string experiences.
    What happened? I am guessing there may be some problems in the Yonex Nano series. Some one have same experiences?

    Can you show us the some pictures such as the stringing machine? How about the broken rackets itself with the strings still attached (if available)?

    stringing at certain tension should be very slowly and carefully, or is ur racket real yonex?

    does your racket frame receive impact often?

    100% sure they are real base on my experiences. The Nano 9K is brand new, first time for stringing. I have sent some pictures to the store for confirmation. But the store is in China (This store guarantees 100% real staffs selling) and I am in Canada. The cost for sending them back to China is high enough for me to consider buying another new one.

    They all broke at 3/9 o'clock when strung the final main string in one side. so I don't think they broke because of impacts.

    Sounds too much to be a coincidence they are all breaking at the 3/9 position, especially on the last main string on one side. Actually, I never heard of anyone breaking rackets while stringing the main, it's usually the cross. I believe your stringing set-up is not ideal or somehow off.

    I have broken 2 rackets:crying: at the 3/9 o'clock position in the past myself, but this was on a 2 point machine when I was just starting to learn to string. From my experience, I believe that the mounting post (at the bottom where you slide it to the size of the frame) were not properly tightened which caused the frame to slowly shorten lengthwise with each main string tensioned and eventually broke... I think at the last main string on one side also. I have since strung maybe 10 or more frames on that 2 pt machine (sold it), but always checked that the mounting post were tight, and have not broken a frame since. I have also strung 20 or more frames on my current 6 pt crank, but still make sure that the mounting post are tight at the bottom... So far no broken rackets:D . Hope this helps:) .

    Great point!
    Yes I didn't pay attention to this and actually I even thought the mounting posts (the top one and the bottom one) shouldn’t be too tightened because I afraid it might make the frame look too long.
    Thanks a lot!!! Great helps!!!

    The bottom adjustment on the mounting post should always be tight so that the racket won't move/shorten during tensioning the mains. The top ones should not to be too tight, just snug, to prevent the frame from getting stretched.

    Ouch... The lessons learned in a very painful and costly way. :cool:

    I wonder how's the shape come out to be, for your 1st 50+ tries? I assume at least some of them should be a bit out of shape? :rolleyes:

    When is your last time you calibrate the tension?
    I think you should check it.

    I used to tie the mounting posts, just changed recently because I feel the frame shape looks a little long. :D
    This lesson is costly but is very useful! Thanks KingO again!
    And also I don't know how to calibrate the tension:confused:
    Thanks everyone for help!

    If the frame looks a bit too long, you are either:

    1) Tightening the north-south mounting posts too tight

    2) Tightening the corner mounts too tight

    3) Tightening all the mounts too tight

    4) Tensioning the cross strings much higher than mains

    And all of the below as indicated by Master Dan. Please post photos of your machine and racket mounted.
