    Default Is it possible to change the location of sweet spot?

    I am new to stringing. How does the location of the sweet spot differentiate from the stringing methods? How can I achieve a sweet spot that is located near the top of the racket?

    The seems to be a consensus that top-down stringing gives the higher sweet spot.

    How is this possible? I only string bottom-up on the crosses on 76-hole rackets (I assume that top-down means that we string the crosses beginning at the top), and I've heard that the sweet spot is where the middles of the strings coincide. Please correct me if I'm wrong, but I think I'm missing some vital information that governs why top-down stringing gives a higher sweet spot.

    I would have thought by string top to bottom your would have lowered the sweat spot.

    I feel when you string from top to bottom you are applying more pressure at the top, at the initial stage and therefore the head is more compressed from the top.

    If you are stringing from bottom to top you are forcing the top head area to by widen at the initial stage by compressing the bottom throat

    I've noticed top down has more responsive stringbed and consistent tension feel.

    Its really hard to make some theories...

    Are there any FEM Simulations made of the racket stringed or even the stringing process? And the sweet spot how is it defined in a physical way? Area with the lowest tension? Area with longest possible elongation at shuttle impact? How do static and dynamic frame parameters influence the sweet spot? etc...
    I think there can be derived a lot of ideas for possible PhD thesis or scientific papers. To find the theoretical best possible stringing method.

    But nevertheless what for us badminton players counts, is that the stringing is resulted in a responsive string-bed. And if trial and error results in that top down is better then bottom up it is o.k. for us.

    Firstly, thanks for these pictures - a perfect illustration of what happens to a racket and why side support placement is so important.

    To be honest, racket safety is my priority these days (especially at my tension), and data suggests that fewer rackets break when done bottom up than top down, so that's the way I'm going now. I may do a blind TD vs BU test soon, though, as I'm in the rare position of having three identical rackets and three identical strings.

    Do you mean break while stringing or during playing?

    Can't wait for your test results...

    While stringing.

    You may remember that Yonex changed their instructions from top-down back to bottom-up a little while ago - rackets were, apparently, breaking while being done top-down at tournaments. Since the change, problem solved.

    When my Gosen gets here I'll do a head-to head - I'll somehow have to disguise the knots.

    I was taught by a All England Yonex Stringer and he also suggested to string bottom to top for the crosses.

    From my personal experience it feels much safe option to string from bottom to top. The reason being why I say this, I have noticed when I string the mains it feel more pressure is applied at the 4 o'clock and 8 clock arm support.

    When I have completed a racket and disengaging the arm supports, I find the top arm support around 2 o'clock and 10 o'clock do not touch the racket by a millimetre. However there's always a bit of pressure around 4 o'clock and 8 clock arm support.

    Is this the case for anyone else?

    I believe Mark is an AE stringer! lol

    But to answer your question, yes that's normal - but some racquets tend to be better that others. For example, when I string my 8DX or JJS, they hardly move. Whereas when I string more flexible racquets, it does - esp oval racquets. What I tend to do is move the supports closer to make up the gap to prevent the frame from moving side to side when doing the last few crosses. But only just enough to close the gap - i.e. not to load the frame anymore.

    I always string bottom up as I string one piece and haven't broken a single racquet so far (touches wood) and I string most of my own racquets at 30lb and above.

    Hey R20190, What does AE represent?

    Thank you replaying and sharing about the arm support. I will take that down in my notes. Just trying to learn much as possible about stringing, and trying to share what i have learnt.

    No worries, we're all still learning off each other...

    But maybe here are some questions while we have these qualified stringers are here...

    1. Cross strings! A) what do you do to weave the strings so quickly? I always need to pull more string in to continue across the strings. B) For crosses, do you do local preweave, no preweave, or full preweave (or some mixture)?

    2. What do people mean when they say that BG80 shrieks when it is pulled? (same with Victor VS-850) thread: http://www.badmintoncentral.com/foru...c-String/page2 I am an impressionable person. Is it actually scary?

    Also, copying off of a thread in the training and techniques section: What was your biggest badminton insight in stringing? (shaved the most off of your time maybe?)
    Thank you for your help!

    do softweave, and plus lots of pratice.

    BG80 is pretty durable. there are other strings like NBG98 which gives a stuttering sound when the rubbery surface rubs against the grommet.

    yup. that's the case.

    4/8 o'clock the frame is already bulged up, using your balloon illustration by going top-down will bulge it even more and eventually the frame can give. this is very rare case though, it means the frame need to be weak to begin with and the support poor (either weak or in the wrong position)

    I'll tell you what would settle this matter for us: a GIF of a racket being compressed from the top so we can see which part bulges the most from its default position...

    Like you, I suspect it's more towards the bottom than the top, in which case bottom-up would get the stress away from that area faster than top-down.

    When I have completed a racket and disengaging the arm supports, I find the top arm support around 2 o'clock and 10 o'clock do not touch the racket by a millimetre. However there's always a bit of pressure around 4 o'clock and 8 clock arm support.

    Is this the case for anyone else?
    Yes - when I do top-down I notice quite a bit of loosening of the top side supports, but almost none when doing bottom-up. This is what suggested to me that the latter is the safer way, as it is keeping the frame shape closer to its empty state.

    P.S. I did the All England for Victor this year with paulstewart64, and we did every racket bottom-up - no breakages.
