    Hi Eepak,

    Regarding to the off-spec, weight from 4U to 3U is unacceptable since it is impossible to reduce weight.

    But for the b/p, would an off-spec E-1000 to be on-spec after added replacement grip or thicker string (assumed thicker string will add a little bit weight than BG66)?? In this case, some off-spec E-1000 may be applicable for those players need thicker grip or smaller grip size.

    E-1000 is a very good racket, I am a lucky person with perfect match in stiffness, tension and grip size, but I still think it is too much requirements on player.

    Yes I totally agree. In FACT I have said something similar in the past.

    Eepak,

    I could be mistaken but I was under the impression that he was referring to a broken shaft.

    I think the main reason why the racquet only perform within such a narrow spec'ed tolerance is because its shaft is flexible. BP deviations would have lesser effect on stiff/extra still shaft racquets. Agree with Linus and forrestyung, it's too much trouble for many players to keep the e1000 on-spec as people have different string and grip preference. Not everyone is going to use a ruler to measure the BP everytime they change grip and string. I'm used to stiff racquets, and more of an arm player. The e1000 I have is strung at 29x31, the BP is 10mm lower than the optimum BP given by EePak after I put on over grip. I just can't play with such a small grip. Clears, drives, and overall defense is great and effortless, just a simple flick and you get the whip feeling. But I'm having problems getting power in my smashes. It feels as the racquet is too flexible, lagging behind my swing when I smash and doesn't snap back to generate the power. Either I haven't time it right or I just don't use enough wrist when I smash. I doubt its because the BP is off-spec, since I can feel I'm hitting the sweet spot every time. But just so we don't start another debate, I'll get the BP back to where it was suppose to be and see if there's a difference.

    because i think design deficiency contributed most of the problem. It is a 4U, these tends to break easier.

    All this talk about off spec of BP and weights HAVE LITTLE to do with racket self destruction. Actually, i read that some of the off spec rackets were related to being 'overweighted' 3U, which by common sense, supposed TO BE STRONGER than an on spec 4U version. If u read most of the off spec talk by taneepak, they were mostly related to BP, it has very little to do with racket structural weakness.

    If the b/p is lower by 10mm the tip of the frame loses some power when smashing, especially if the tension is as high as 29/31lbs. You may not feel it, the repulsion of the racquet is also reduced for clears, drives, and return of smashes. You need to increase the swingweight, not by increasing overall weight, but by reducing weight anywhere from the b/p to the butt end. The most effective way is to reduce weight at the most extreme end of the butt. This increase in swingweight will improve the whip-like action for downward strokes like smashes, making them sharper. At 29/31lbs a higher b/p of 31.0cm would be marginally better than 30.8cm.

    Generally it is true that it is impossible to reduce a 3U racquet to 4U. However, in the case of the earlier batches of E-1000 the off-spec 3U were also off specs in their b/p downwards by quite a significant margin. These off-specs on two properties of the E-1000, fortunately, can be offset against each other. That was how I remodified them to be on-specs again.
    The weight of strings will have no impact on the racquet's playability. The remodified E-1000 was modeled on a very light BG66 string strung at high tension. Other heavier strings will not make any difference, despite its puny increase in swingweight.
    The earlier E-1000 with its rather small G5 grip can actually be modified to be G5/G4 compatible to its ideal b/p. Modifying it to make a G3 grip compatible can be a bit difficult and even dangerous for the person doing it. It also serves no useful purpose as such a G3 grip on an original G5 wooden hold will make the bevels disappear and the handle almost completely round.

    Hi guys, I counted the hole number and with the E-1000 the breakage was at hole number 11. With the E-5000 the breakage was between hole # 10 and 11; but closer to hole number 10.

    Taneepak, I seriously doubt it was the stringing. The guy has done about 30 to 40 jobs for me in the last 3 months. Lowest tension being 24lbs; highest at 29lbs, and no other racktet has broken.

    I will measure the on spec e-1000's BP and post it here. Currently it is decked out with bg66 and ashaway rubber grips.

    Another question: you mentioned two (2) sweet spots?? how is that??

    regards

    The COP is above the COR. The COP is a point in the middle of the sweetspot that curves somewhere near and joining the 10 to 2 o'clock. The COR is lower down. The sweetspot is the spot where if you hit a shot, you know you are in heaven.:D
    You can try this : hold the handle of your racquet and clamp the handle tight on a table with your left hand, and leave the frame hanging over the table. Now drop a shuttle from a height onto the 2 sweetspots. They will bounce. The more they bounce and the higher up the frame they bounce the better tuned your racquet is. The very tip of the racquet registers no bounce. This is ok so long as the no bounce does not go much further down the frame. The greater the bounce over a greater area the more effortless your shots are, because the bounce does most of the job for you.
    The hardest test for good bounce is to flick a return from a hard smash with your forhand to the extreme backline of your opponent. A backhand flick is also a good test but it is easier than the forehand flick.

    It is very unlikely that the E-1000 frame will break by itself. Its frame is extremely strong and extreme high tensions of 31lbs is handled without any strain. However, when you clash a racquet, including an E-1000, then anything can happen, either right away or it will come back to haunt you later, like breaking even without hitting a shot.
    Also sometimes if you clash a racquet with another racquet square on, like a hard smash into another racquet, you may even fracture the shaft besides breaking or chipping the frame if there is no breakage.

    How are you defining swingweight now?
    Because if it's the sum of mass x (distance from axis squared)
    then you can't increase the swingweight by removing mass

    you can move the balance point, but removing mass will decrease the swingweight.

    Pball asked how is it possible to have 2 sweetspots, and MR. eepak answered
    LMAO !!!!! I am surprised no one has googled COP and COR yet. The COR is not lower than COP because its not even an area but its just an coefficient between 0 and 1. Therefore, its not possible to have 2 sweet spots. By definition, COP ( Center of Percussion) IS the only sweet spot. COR ( Coefficient of Restitution) is just a coefficient between two objects energy retention after a collision.


    "COR" is an acronym for "coefficient of restitution." Coefficient of restitution is a measurement of the energy loss or retention when two objects collide. The COR measurement is always expressed as a number between 0.000 (meaning all energy is lost in the collision) and 1.000 (which means a perfect, elastic collision in which all energy is transferred from one object to the other).

    htt://golf.about.com/od/faqs/f/cor.htmp


    In golf, the COR is even restricted for the club head:

    "The current USGA rule limiting the coefficient of restitution of a clubhead states that the COR cannot be higher than a measurement of 0.830. This means that when the clubhead impacts the ball, there cannot be more than an 83-percent transfer of the energy of the head to the ball. "

    Here is the link from harvard.edu about COP. for those that like to read.

    http://www.fas.harvard.edu/~scdiroff/lds/NewtonianMechanics/CenterofPercussion/CenterofPercussion.html

    Quote: "The center of percussion (COP) is the place on a bat or racket where it may be struck without causing reaction at the point of support. When a ball is hit at this spot, the contact feels good and the ball seems to spring away with its greatest speed and therefore this is often referred to as the sweet spot. At points other than this spot, the bat or racket may vibrate or even sting your hands. This experiment shows the effect by demonstrating what happens when you strike a suspended model of a bat at various places. "


    Once again, dont believe everything you read sometimes. LOL. Eventhough there is alot of "heavy" and scientific terms are used. :)

    What are you going to do? Sand down your STB-5071 (Berlin Passion)? Heck, even then it'll still be more durable then an NS9000. :p :p :p *ducks then runs*:p :p

    How can a racket have two sweet spots? It's impossible. The only way would be for both spots to have identical and maximum repulsive/power transfer properties. :confused: Two sweet spots just doesn't make sense on one racket.

    Please enlighten.

    A simple search in Google will tell you that COR is just a number, not an area ( spot). In fact, COR is under strict regulations in Golf clubs that it can not be greater than .83 or another words then club head can not transfer more than 83% of the energy to the ball !

    There is only one sweet spot, its just that when someone uses alot of "big" terms it sounds almost possible.

    Just some background information on swingweight:

    "Michael Lamanna, Director of Instruction at The Academy at La Cantera in San Antonio, Texas, puts Maltby's definition in easier-to-understand terms: "Swingweight is a balance measurement and is the degree to which the club balances toward the clubhead." If Club A has a balance point closer to the clubhead than Club B, then Club A will feel heavier in the swing."

    Using this definition, an "ON SPEC" E-1000 racket should have a heavy feel due to the heavy swing weight because BP is shifted closer to the frame thus might be contracdicting to call it effortless power.




    Here is the swingweight and how it's seen in golf that may or may not apply to badminton.


    "But how important is swingweight, really? Recreational golfers who fancy themselves equipment "experts" - you know the type - might argue that it is very important, and for many golfers, they are right.
    But not everyone is convinced that swingweight is something most recreational golfers need to lose sleep over.
    Lamanna, for one, says, "In my experience, most players can only sense large differences in swingweights, and even Tour pros have a hard time telling the difference in swingweight between clubs with different shafts."
    Lamanna says the focus seems to be shifting back to total weight as the key weight measurement. "It seems in the past 10 years there has been a reduced emphasis on swingweight by club manufacturers. The overall weight of the club - in particular the shaft gram weight - is these days the measurement upon which they focus. "Research indicates that lighter shafts are, in general, better for the average golfer. Less weight produces shots of greater distance and accuracy for beginning and intermediate players. The low handicappers and pros have higher swing speeds, more control over the movements of the club and they possess an acute sense of 'feel' for the head of the club. The shafts best suited for them typically are higher in gram weight and have heavier swingweights."
