    Those last three mains ...

    If your idea of average out tension is true, how long do you think will that happen? Remember the variable of time. From my own observation using SM, the answer is NO. Even for Kevlar, which I can move the main tension by pressing down on it, without cross. Plus pulled tension and actual...

    Those last three mains ...

    You may want to look into the origin of JET stringing method, for background. I will not be able to describe it that well. The reason I go to this pattern, essentially -4 lb @ M4,5,6, is that the tension adjustment is relatively minor or say simple. The effect is almost like proportional. Yes, I...

    Those last three mains ...

    If you are looking for a pattern, get in the habit of recording 16 main +19 cross readings for the life of the string bed. I also do that for essentially all the string job I did for my own sticks. It is very illuminating. What you observe first hand cut through a lot of opinions out there...

    Physics and Tennis

    I wish him luck. I do wish the presentation on the website shows more "science" or fact based information/argument. The video of loose grip presented an opinion or perspective based on certain mental image or model. His model or idea is not unique among the many models already existed...

    Serve tips!

    Hello Chas, I respect you and appreciate your enthusiasm and your intense pursuit in tennis. I am also very interested and very curious about how tennis is played. But I do not have the credibility of being a high level player, though my hitting partner thinks so. And I only help coach high...

    Forehand groundstrokes linear or circular when looked from above?

    At last an interesting subject to ponder on. Hopefully we can all be open-minded, can think and learn about it more. Now let's define the "stroke", are we talking about the motion of a racket, the racket face, or the hand or arm? Or if we are being general, then the answer is general and only...

    Serve tips!

    There are many elements that makes up a sound service motion, staying more sideway is one. If I were you I would focus on the most essential part, which is how the racket moves. Why racket? What makes the ball goes? Racket face. What moves the racket? Your hand? I think you probably have more...

    Serve tips!

    The focus is finding the solution. Let's not focus on the problem. A few things to try: To find the motion keeping the torso more sideways, serve on your knees. Try shadow swings first. abreviated arm motion starting from "solute" position. Go through drop (scratch your back) and gently pull...

    What was the last movie you watched?

    I also enjoyed watching it very much. Very emotionally engaging and the most impressive air combat scene I have seen. Highly recommended. Now just one regret, I wish I could watch it in the iMax theater. Some movies are meant to be seen in the IMax, such as Dune, another regret. Now, I wish...

    Can you throw over the fence from the baseline? (without taking a running start)

    And now for something completely different.. (Please Skip this post, if you always take the blue pill instead of the red pill..) Knowing that the force that causes an object to move in a circular path is the centripetal force, the force pointing toward the center, when one is generating the...

    Racket tune

    If the purpose is to verify the consistency of string jobs, from one string job to another of the same racket/string/tension combination, the RT may work. RT basically "average" the whole string bed and give you a number to represent the tension. If the purpose to to check if say one or multiple...

    What was the last movie you watched?

    Wow, Zara! Good to see you. I miss you.. and those beautiful food pictures. Anyway, my brother recommended My Octopus Teacher to us while I was visiting my parent. It was an excellent movie, very touching. Oh, I just learned that it won an academy award for a best documentary feature. A man...

    Horse stance on balls of feet

    Look up isometric and eccentric movement for strength building. Yoga, pilate, and QiGong are in this slow movement type of exercise that most ppl do not consider them as exercise. Core strength is fundamentally important to any one who is aging or have any kind of leg/knee/back issues. It is not...

    Plantar Fasciitis- What helped you?

    Acute pf, yes, a lot of tips have been posted. If it does not go away or come back again then the pf is the syptom for something else, such as knee, hip or back problem. Fix those n work on strengthening your core/lkwer body. Then the problem can be managed.

    Shoulder pain after serving - poly or heavier racquet?

    Adjust the service motion, rhyme with the new racket. Else your body might be telling you something about the service motion.

    Horse stance on balls of feet

    Holding a squat position or simply stand with a little bent in the knees for 15 to 20 min. daily or do baduanjin is good for anyone's general quality of life. The benefit is very noticeable for the aging bodies or people with feet, knees or back issues. But really what is not as important as...

    Do you use some version of proportional stringing?

    What is your preference currently for your own frame? For me, I like JET-like for main, i.e. dropping 3-4 lbs on #4, 5, 6. Cross I kept constant. I string 16g poly at mostly low 40. I suspect that going to 35 lbs for poly is probably pretty close to JET @ 40 lb.

    2 lbs drop, big change?

    "Checked tension" - I assume that you are using Racket tune and it gives one number representing an average of some characteristic on the string bed. First question is what constitute "spot on". Any kind of measuring device has some kind of tolerance or uncertainty. A regular metric ruler that...

    Do you use some version of proportional stringing?

    Please search for JET or JayCee stringing on Gut n Glory tennis for the original description of the procedure. My thought is that last two mains does not affect the string bed performance much. Higher last main can compensate for the stretch of untensioned string outside the frame. And for the...

    Do you use some version of proportional stringing?

    I suggest that you use StringMeter to measure each of the mains and cross strings after strung. Once you see the numbers then your stringbed will be more than your imagination and your "feel". I habitually measure each of my strung rackets and I use something inspired by JET or JayCee method...

    How do i fix my serve? God awful form

    Focus on what to Do rather than what NOT to do. In that way of thinking, then I suggest that you BUILD a solid and sound serves rather fixing a bad one. If you do enough correct or right things, then you will have a pretty good serves. If you have to self coach then I suggest Feel tennis and...

    lower tension in the centre string?

    I am assuming that you strung yourself and you measured the 16 or 18 main strings with SM after stringing. First keep in mind that the smallest unit on a SM is 5 lbs. So any reading you get is + or - 2.5 lbs. I use SM regularly on all my sticks that I strung. And I observed a bunch of stuff but...

    Modifying a Gamma II fir 360-degree swivel?

    Interesting! Gamma FC602 FC user here. My turntable turns all the way around, now. The handle has about 4 or 5 mm over the ratchet. From memory, I think I messed with the turntable when I got it about 4 or 5 years ago. I thought the turntable bearing was bad because it seems to have some play...

    Long-lasting, comfortable string?

    I read somewhere that one can only get two out of three: Longevity, cheap and "Good". But here are my picks: Thick gauge Natural gut Low tension poly, say like 35 lb Isospeed Baseline. Woven Kev/synthetic gut hybrid

    Tie off strings on the outside extremely loose

    If you like the last main tighter, you might want to look for a Richard Parnell's video. He demonstrated a lock, locking the end string under the strung main. He pull the string tight and wrap it around, depending on which way the string goes, pull along the main direction then the tensioned...

    One handed backhand feedback

    Again I applaud your effort. One observation I have on your video shadow swinging in the yard is that the muscles are .. tense. You can do everything else right, but being tense you are holding the "energy" in, instead of letting it go toward the ball. So relax. One of the thing that many...

    Low Tension Club under 40lbs

    You might need a bit of time to adjust to the change in "launch angle", else up the tension a bit to 20 or 21 kg. 19 kg -> 18.2 kg about 5% drop. That is actually very little drop because my SM's smallest unit is 5 lbs, only accurate to 2.5 lbs. Thus 5% drop would not be "significant". I suspect...

    Modulating Spin, Toss and Pace for Better Serve Consistency, which technical aspect to focus on mainly

    Nice catching the video with additional data. I envy your setup. There is effort and there is intention, both are great for improving. If I see my students doing what you are doing, I would think that they are still looking for the "right service motion". And before you find the flow, the...

    Low Tension Club under 40lbs

    I am not a string breaker, so YMMV. This Prince Michael Chang Graphite OS LB was strung in 2019 December with Isospeed Baseline 16 @ 35lbs. (actually with proportional stringing, reducing from 35 to 27 lbs in the mains. Though I do not play with the same stick all the time, this was one of my...

    Backhand and forehand slice. A punch or a swing?

    Ok, but stable is not necessarily tensioned. You can miss the nail by being tight too. So what drives the nail? The momentum of the hammer head, not your hand? Otherwise why are there different mass hammer? I am saying after the contact, what you do with the racket does not matter to the ball...
