    Given the specification variances that have come about from the same models of different rackets, I thought we could have a thread to pool together all results to keep track of which rackets have the most variance, and which are more consistent.

    It will also give us a quick, accurate, real world idea of how different rackets stack up.


    ----------


    1 . Racket Details.

    Simply post the Make, Model and Specification of your racket.


    ----------

    2 . Measuring the Balance Point.

    You achieve this by placing the shaft of the racket on a thin edge of some kind (the thinner the better), so that there is nothing to support the racket on either side, and until it balances perfectly without tipping over either side.

    After you find the exact point it needs to be positioned to balance, mark it somehow, or keep a record of exactly where it is. This is the balancing point (bp). I find it's easier to mark it by using the letters found on the small print on the side of the shafts.

    After that, measure from the end of the racket (bottom of the handle) to that exact balancing point marked earlier. The total length from the bottom of the racket to that point is the bp.

    ----------

    3 . Measuring the weight.

    Simply weigh your racket using an accurate scale. Make sure either side of the racket is not touching anything, and that the full weight of the racket is on the scale.

    [​IMG]

    ----------

    The rules of measuring.


    - Make sure the racket is un-strung, and has only the factory grip, with no other plastic wrapping, cellophane, over grips or anything else on it that could skew the balance.

    * If your racket differs from the above during measuring, please state how.

    - Post results in millimetres and grams.


    Please post your results in the format below


    ----------

    I'll start us off.

    I think [MENTION=57143]visor[/MENTION] had started off such an initiative a while ago. The various specifications of the racquet were collected and the swing weight was then measured as well by a formula.

    The factory plastic wrapping on the handle reduces BP by 4-6mm depending on if it's single layered or double. A double layered cellophane wrap (with the little specs sticker attached), like the ones you get on new Victor rackets, weighs roughly 2.5 grams.

    The BP on my JJS was 300mm with all the plastic wrapping on the handle on, and 306mm with it off.

    It not every time to reduce 4-6mm with plastic warp. It up to specs paper.

    My Yonex 2 rackets don't have specs paper, its less than 1 gram. Then its not so much to effect BP. ( not more than 1mm)
    but Lining have specs paper that stick in plastic warp. (plus around 4-6mm that u said)

    Therefore information receiver should consider about it.

    From one of my friend racket.

    Great post. Thanks for the insight.

    All of my rackets came with the specs paper, some with double wrapping, so I guess that explains the difference.

    ^ wow... the wrapper weighed 0 grams! ;)

    seriously, though, to properly do this, we all need to weigh with a digital scale that is accurate to at least 0.1g

    and you can't just have bp reading without wt, just as you can't have wt without bp... meaningless...

    I'm using a Digital Scale accurate to that degree. I actually also have one accurate to 0.001g, which I use for my Jewellery business. But I'd rather not use that one for weighing badminton rackets! :p

    and obviously the bp shift from extra weight on the handle (eg. wrapping, overgrip) will not always be 4-6mm, because it totally depends on the difference in mass on both sides of the bp

    ​This was my thread that cobalt was referring to:

    http://www.badmintoncentral.com/for...n-easier-simpler-appoximation-of-swing-weight

    And the following post is the conclusion that I came to regarding the relationship between head wt, total wt, and bp using summation of moments on a simple rod.

    Definitely, which is why I think it better if people just measure without the string, wrapping or grips. Get a much more accurate measurement that way. Having said that, it's fine if people can't measure this way either as it still gives a rough indication.

    On a side note, it would be great to have more results from other rackets posted.

    Thought I'd update with some added details on a few different rackets, as well re-measurements post digital scale calibration.

    No strings or additional grip.

    Victor MX90 3U/G5
    - With plastic handle wrapping | 89.8g, 290mm BP.
    - Without plastic wrapping | 87.3g, 301mm BP.
    - Shaft | diameter 7.25mm.
    - Frame | diameter 6.95mm.
    - Stiffness | 7/10.

    Victor MX JJS 4U/G5
    - With plastic handle wrapping | 300mm BP.
    - Without plastic wrapping | 85.3g, 306mm BP.
    - Shaft | diameter 7.49mm (also shorter than all my other rackets by 2-3mm).
    - Frame | diameter 6.88mm.
    - Stiffness | 8/10 with a higher point of flex than my other rackets.

    Yonex VT80 4U/G5
    - Without plastic wrapping | 305mm BP.
    - Shaft | 6.89mm
    - Frame | 6.62mm
    - Stiffness | 8/10.

    Victor BS12 3U/G4
    - Shaft | 7.42mm
    - Frame | 6.96mm
    - Stiffness | 8/10.


    Now I know Victor claim the BS12 is medium stiff, but my non scientific testing says otherwise. It is however head lighter as their specs state.

    Maybe we need to bring [MENTION=30877]AlanY[/MENTION] into this thread, for his expertise with tables and shared files and stuff! :)

    Fantastic effort. Once we get enough I'll put them in to a easy to read table.

    By the way, none of my rackets have the throat part as shown in the diagram. I think it's usually cheaper rackets that have that bit sticking out. Generally the aluminium ones.

    You are welcome and I agree with you with the throat part, most of the racket now use an inside frame T joint. I just wanted to be clear with my data.

    Yonex ZF2 4U/G4
    - With plastic handle wrapping | 84.7g, 305mm BP.
    - Without plastic wrapping | 83.6g, 308mm BP.
    - Shaft | diameter 6.61mm (thinner than any of my other rackets).
    - Frame | diameter 6.28mm (thinner than any of my other rackets).
    - Stiffness | 9/10.

    Racket: Yonex Voltric 7 NEO
    Specification: 3U/G4
    Balancing Point: 327 mm from Handle - Head Heavy
    Flex: Stiff (52mm)
    length: 10 mm
    Weight*: 90 g
    Head Shape: Isometric

    My favorite Racket.:)I have played with this one for a couple months. Bought it for about $80. https://bestoutdooritems.com/best-badminton-rackets/ It's a lightweight racket that feels great to hit.After playing with Yonex Nanoray 20, this racket has improved my game;).Very good balance, but not a good smasher.
