Master Paizhuan Stringing Pattern

I was studying the coach's racket and discovered that the stringing pattern on it was more superior than the conventional stringing pattern offered commercially by most of the stringing shops. I searched in BadmintonCentral and finally found this pattern which resembles the one used by the coach. Its called the Master Paizhuan stringing pattern. Heres why...

What is the Master Paizhuan pattern?
The Master Paizhuan pattern is a one piece top-bottom style pattern, originally designed for 72 hole rackets. You start by doing the first 16 mains, then you do the top 4 crosses, 1 more main on each side, then the bottom 4 crosses. The short side then ties off, while the long side goes back up to the top to string bottom down the balance 13 crosses. The 11th or 12th main is the last pull on both sides.

There will be a slight improvisation needed for rackets with 76 holes which most of you are using locally here. Preweaved, you will never have to fight with shared holes.

But why would you do this?
With the regular bottom up pattern, you lose tension in the sweetspot very quickly. This happens because you have more slack at the top, with the knot (which just doesn't hold as much tension), and because it's harder to clamp up there. I feel like you then get some tension creep.

The Paizhuan pattern, move all of the slack onto the outside main - the 12th string... a string you'll never actively use. Upon completion you will notice immediately the stringbed is more balanced and feels firm. The sound reverberates better as well.

Those who like to try your rackets using this pattern, the attached drawing will assist you or your stringer.
This is an improvised pattern for 76 hole racket used by Ryan. Yellow Short String. Green Long String. Notice the 2 tie offs are modified to 11th main string.
If you are not into the technical details of it, just send your rackets to Aaron or myself. We will string it for you by giving advance notice.

Stringing our 20th Racket

Its a small milestone but what better way to mark it with a small present for Ryan. When the string on his weapon of choice, Yonex Nanospeed 990 snapped, I decided to give it a complete makeover with full epoxy treatment on the cracked segment of the frame and a complete paint respray and finished with clear coat. The grommets were replaced and strung with two lengths of recycled strings strung at 25 lbs (main) and 26 lbs (cross) at proportionate tension. Those using Taiwan Yonex will know the rated tension is no more than 24 lbs but I was risking it to test the strength of the epoxy glue. To my surprise, the racket held the tension well despite the cracked joint at 10 o'clock. Ryan gave me a sheepish smile with the new look of his racket asking me... "eh daddy, how you do it arr...?" For those who have been close to the boys may probably noticed Ryan has scaled down his training hours in favour of his ever increasing school homework in preparation for his "O" level exams. He still trains with Persatuan, the club and privately with Aaron and I. He has just broken his voice a few weeks ago and in transition of entering into teenagehood. I have started to inject 30mins of gymn exercises after their usual on court sessions. He certainly is growing up having a mind of his own. So the journey continues....

Aaron's First Title in 2016

With nothing to show for in the 2016 national junior circuit under 14 category, I enrolled the boys in a private tournament in May, Dr Pro-Aero Sports-WVN Jr Round Robin Badminton Championship which has a surprise coverage by the Badminton Unlimited. Aaron was in his element topping his group and went on all the way to win in the finals. The results are published here in the link..

DIY Grommet Inserts

Note the 3 string overlap at the bottom insert.
Before tensioning but the plastic is still too soft. 

Aaron has a Protech Tangerine which suffered a collapsed in the frame between the 8th & 9th hole both sides of the racket. This is the highest stress point in any racket because of the shared strings between the mains and the cross. Sometimes, depends on the weave pattern, both holes have to withstand the tension of 3 overlap strings. Wish racket manufacturers can design rackets with stronger material on these points. I have carved out simple plastic grommet supports inserts to help stiffen the bridge between hole 8 & 9 made from shuttle tube plastic cover because it is soft and easy to cut into shape with a sissors. However this plastic material is still not strong enough to hold the string tension. I may have to source for alternative materials around the house. Maybe a CD cover? Any suggestions from the readers?

Acquiring a Stringing Machine

Pre-weave from 200m reel-to min wastages
4 point Fleet Crank Type Stringing Equipment

My first racket strung was my daughter's beat up Yonex

Done! After more than 3 hours for a first timer.
I was just lamenting how easily racket string snaps nowadays. At the rate the strings were giving way, I might as well string the rackets myself and that was exactly what Aaron has suggested to me one day. I was warming up to the idea but only a used stringing machine was all I could afford at the moment. As I was sourcing around, I met coach Collins during one of the boys training sessions. A connoisseur on badminton subject matter, my chats with him has always been enlightening. When I brought up my desire to acquire a stringing machine, I hit the jackpot. Immediately he sold me his manual stringing machine just like that.  

Thanks to coach Collins, I have bought over his Fleet crank type stringing machine c/w all accessories. When I brought it home two days later, being a curious person he is, Aaron couldn’t stop fiddling with it. I immersed myself into the art and techniques of stringing rackets and I had to accelerate my learning curve because Aaron couldn’t wait to sting his first racket. Being a fast learner, Aaron can now fully weave a racket without supervision. There were loads of “how to” videos in Youtube and great stringing resource sticky pinned in Badminton Central forum which is easily available.

The good thing about stringing my own rackets is that I could experiment with different string types and string gauges and different combinations of string tension to meet the playing preference of the boys. It has become my SOP now to pre-stretch new strings (to reduce tension loss, post stringing) and have Aaron to fully local weave the racket first before I take over on the stringing machine to save time. Our rackets now get proportional tension treatment to enlarge the sweet spot on the racket. My first racket, Kiera’s Yonex took me more than 3 hours to complete. Since then, the time has tumbled down to less than an hour (including grommet adjustments). Perhaps there is no pressure for me to speed up the stringing process since I am a meticulous DIY person by nature and pride myself in the quality of work produced. Nevertheless, the duration will come down as I get to string more rackets. For the record, the rackets I have been tweaking so far are as follows :

Yonex Arcsaber 009DX - Kiera’s                               Main 20 Lbs / Cross 22 Lbs (2 knots)
Dr Pro Ultrapower 569 – Aaron’s                               Main 22 Lbs / Cross 24 Lbs (4 knots)
Babolat X Act 85 – Colin’s                                        Main 25 Lbs / Cross 26 Lbs (2 knots)
Yonex Nanospeed 990 – Ryan’s                               Main 24 Lbs / Cross 24 Lbs (4 knots)
Protech Legendary Platinum – Aaron’s                      Main 25 Lbs / Cross 25.5 Lbs (2 knots)
Yonex Nanospeed 990 – Ryan’s                               Proportional Tension 20 – 26 Lbs (2 knots)
Protech Legendary Grand – Kiera’s                           Proportional Tension 18 – 22 Lbs (10 knots)

Wilson Dynapower 9500 – Customer’s                       Main 25 Lbs / Cross 26 Lbs (2 knots)

Protech Racket Repair

This grommetless racket has 5 strings and 10 knots strung at 18 to 21 Lbs proportionate tension.

Protech Legendary Grand - has seen better days. Its duties now relegated from competition to recreational use by my 6 year old daughter.

The frame cracked right through a string hole.
Close up on the inside after the DIY glue job.

DIY the logo stencil for a good measure.
Hi. I'm back after a 6 months hiatus due to outstation work commitments. Secondly, my pc was infected by ransomware which resulted in all my data being encrypted. I had to recover and update all lost data from my backup. Im still updating as I write. 

Anyway in my absence here, I have acquired a used stringing machine. This has occupied part of my time learning how to string the boys rackets. There will be another post for this.

One of the rackets which I bought last year, a Protech Legendary Grand, developed a crack on the frame at 10 o'clock. I love the feel of Protech rackets. Although it is light headed but with the longer and slimmer shaft, it gives a whippy feel about it. Unfortunately these rackets are fragile and need lots of care playing with it.

So Aaron clashed this new racket during his doubles sparring and what a waste to toss it away. So I decided to repair it using industrial '2 in 1' epoxy glue. Then I strung it using 5 offrun strings at proportional tension between 18 to 21 Lbs. Yes you heard that right. Thats 10 knots.The result are as in the pictorials above.

I dont expect this battle weary racket to last long anyway. It will be for Aaron to hone his stringing  skills and knotting techniques.
