    Hi

    I was thinking to string my racket, but then I read in this forum that people have not just 23lbs, 24lbs etc. They have 23x25lbs , 24x26lbs etc. :confused:

    Which one is better if I have a iso metric shaped racket (AT 500) ? :D

    Which way is main and which is cross? :D

    thx

    Not trying to confuse anyone, but the general "cross add 10%" rule not apply for every case. It really depends on the machine setup. Therefore, you should talk to your stringer, before make an assumption of "1 method rules all". There are special machine setups, does not require the 10%, or even extra tension on the main. :rolleyes:

    I wonder if that demonstrates in reality is how many cross/mains darkwingduck actually get the rackets stringed!! :D

    LOLz..it would be funni if u string ur racket @ 25/23 since the idea of mains and crosses are "reversed" here..haha..the racket would end up looking like a ball..

    Irrespective of machine type, machine set-up, or stringing technique the crosses should always be strung at a higher tension than the mains. This is because you need the extra tension on the crosses to offset the increased resistance the crosses have to face now that they are weaved over and under the mains. Remember, the mains do not have any crosses to impede them when you string and tension them. The objective is to have an "effective tension" that is equal for the mains and the crosses. If you use the same tension for both mains and crosses you will have an "effective" tension of the crosses that will be lower than the effective tension of the mains.
    It is possible to have frame distortion even with the above, especially on oval-shaped frame and less skilled stringers. This is due to machine type, stringing technique, positioning of the supports, etc. However, although you may be able to string a racquet with no discernable distortion at say higher mains tension than crosses (the opposite of conventional wisdom), mainly by using force to "stretch" the frame with the posts, n/s clamps, and or side supports, you will end up with a frame that is constantly under stress. A higher cross tension over mains will come closer to an equal "effective" tensions for both, which means zero stress on the frame.

    the problem is, with some technique, even equal tension between cross and main will result narrower frame, can you imagine to add more pound to the cross tension with that certain technique?

    A fundamental error, if not corrected, will destroy even the strongest structure. Narrower frames are usually due to overstretching of the frame at the two n/s posts, a very serious fundamental mistake. Load spreaders and the n/s posts are not meant to support or take any stress from the tensioning. Such devices are used only in suspension systems, which only get their support from the 4 side supports. Using load spreaders and/or the two posts to "stretch" the frame on suspension systems is a fundamental mistake.

    I disagree about "always".
    I string my own racquets any way I like such that I prefer the "feel" of it.
    Currently, this is 20m x 19c (with BG66)
    I don't care if the racquet is "under stress" or not.
    Will the racquet last me 6 years instead of 8 ?
    Will it be replaced by a newer racquet before the "stress" makes any difference?
    Who can say?

    As you so often say, "Think outside the box".


    Any strung frame is under stress.
    Instead of zero stress you should maybe say "balanced stress".
    Even then, is crosses +10% more balanced than proportional stringing ?

    agree that it is not always the case as illustrated (lazy to find the link) by KDM's racket having higher tension on the mains compared to the crosses hence his iso racket looking more circular.

    Hi Pete,

    Do you play badminton at high string tension ? Said 27Ibs and above.
    If yes, I would like to find out what stringing does your stringer used.

    Thank you.

    You have to strengthen your forearm, triceps, bicep and shoulder muscles in order to take high tension. Please do a search to find out the type of exercises required.

    I string my own racquets. I use Gamma 6004 crank and LaserFibre (Stringway) drop-weight machines.

    No, you don't have to strengthen all those muscles first before you can play with high tension. I have seen skinny and small female players ranging from 10 years of age to 65 playing at 28/30.5lbs. What you need to have, if you have been playing at low tension, is to slowly adjust to the speed of your swing.
