According to the Yonex stringing pattern (except AT800), when stringing the mains, you come out of B9 (B for Bottom), up through B12, into T11 (T for top), back down through T10 and down through B10 and tie off at B8. My question is; Can you string this pattern if you only have flying clamps? After you tension the string from B12 - T11, how do you clamp it? If you clamp it to B9-T9, the clamp is in the way of the next string, T10-B10.
If you have only flying clamps, you cannot clamp it the way you described. You can get around it by pulling two strings in one go : pull the string at B10. You can compensate the slight loss in tension from pulling two strings by adding a few lbs more.
I never thought of this pattern. I guess the main purpose is to prevent tension lost? (B10 to B8 is shorter distance than B12 to B8)
Yes, a non-tensioned piece of string will sooner or later take up some slack, and the longer it is the more slack. But what is more important about the Yonex pattern is the added safety of not stretching the stress/distortion towards the extreme outer edge. As you string progressively from the centre towards the side, the distortion and stress will also creep outwards. Therefore, after pulling the 9th string, using the Yonex pattern by pulling from the 12th/11th grommet will counter some of this outwards stress/distortion creep, by pushing the stress/distortion inwards.
Please use the search function, as the stringing pattern has been covered before, I just don't remember which thread it was in.
Thanx... I think I'm a little lazy... Do you think that the AT800 pattern could fit a MP for exemple ? Or is it an obligation to use the right side pattern ?
I don't think the AT800 pattern would work for MP rackets because there are extra grommets in the AT800 that are either for the main or cross strings (can't remember which) instead of having both main and cross go through the same grommet.
Because the mains have already been tensioned and strung, the crosses have the advantage of the counterforce from the strung mains to minimize stress. If you string the crosses from the middle, there is minimal advantage of the "go ahead then back" method, which may pose knotting problems.
The stringing pattern referred to here is the one recommended by Yonex for all their racquets except their new Amortec 800, the latter requiring a different stringing pattern because of additional grommets. Stringing pattern is the same for both oval and iso-shaped. For other racquet brands, you have to check with the manufacturers.
the pattern seems a little bit tedious, slow and distracting. hard to keep as a routine trying to remember all that jump about. not the most efficient pattern i might say. besides, there are other ways to reduce slack... more efficient ways
Before the knotting, the extra piece (from B10 or B12 back to B8) could only be min. tension by "hand pulling". Therefore, it's no way being tensioned at 20+ lb as the remaining pieces. Never have to metion, when tying the knot, a lot of tension will be lost.
Can you elaborate a little more, as to why the Yonex pattern is "a little bit tedious, slow....distracting, hard to keep as a routine trying to remember all that jump about...there are other ways to reduce slack..more efficient ways"? Perhaps you can describe to us your more superior methods, if any. We need to compare your methods and see for ourselves the merits of your claims.
to make it clear, the yonex pattern im talking about is the normal racquet in the link provided by Neil. thanks Neil . you will notice alot of hopping about at the ends. it would take lots of practise to get used to this 'odd' pattern and you are most likely to forget or do a mistake. time consuming in the labor and the 'retraining' process. since you are very concerned about frame stress, show me data on how this 'unnatural' pattern does not increase stress on the frame. as about slack, lets just say that tlc in finishing the tie up helps alot. and it would be safe to say most 'slack' or 'tension loss' happens when strings at the sweet spot received high impact upon contact of shuttle causing the string to stretch, thus causing slack. thats why most racquets left in the store are 'almost' the same tension when taken out years later, deterioration of string quality aside. unless its been eaten by a rat of course
For your information, the Yonex stringing pattern for non-AT800 racquets is the de facto industry standard. Why you call it an "odd" pattern may be understandable, given your reluctance to understand its merits. I do not quite understand your timidity in using the pattern, as it is just as easy and as fast as your continuous stringing pattern. It is not as complicated or as daunting as you think. To better understand and appreciate your point of view, can you please describe your own stringing pattern? I have earlier in this thread explained why the Yonex mains stringing pattern towards the edge helps to reduce the outward distortion of the frame when you are stringing from the middle towards the edge. Also, the 10% tension differential of the mains vs the crosses is to equalize the frame to as near a static state as possible. Why, you may ask? Also, 1-piece 2-knot stringing stresses the frame more than 2-piec 4-knot. Do you know why? An experienced stringer like you should know, although I have come across veteran stringers from well known shops in Hong Kong with 30 years stringing experience, using 10% less tension on the crosses than on the mains. However, if you have never heard about this, I will oblige with a more detailed explanation.
