The JET Method of Stringing - - Detailed Step-by-Step Instructions:

Whilst it ideal to have your  racquet strung by a trained and certified  JET technician, the method is still new to the industry and the number of trained technicians is limited.  While the JET Method takes many months to perfect, the process is not a secret and can be learned by any stringer with a desire to be able to achieve the best possible stringing results with L-TEC Premium strings.

RACQUET PREPARATION:

If necessary, carefully use an awl to enlarge the grommet holes on #6 main (16 main pattern) or #7 main (18 main pattern) for tie-off. (This will be either top or bottom depending on where main strings end.)

Enlarge the grommet hole on the third cross from bottom of the frame for tie-off. (Depending on pattern, this can sometimes vary. The objective is to tie-off as close to the 2nd to last cross as possible).

 MAIN STRINGS:

1. String first four center mains on each side at reference tension.
2. Next 2 (on 16 mains) or 3 (on 18 mains) reduce tension by 4 pounds.
3. On a 16 main pattern after pulling main #6 skip over to #8. Increase tension 4 pounds (to reference tension) before tensioning.  (#8 will be pulled at reference tension).  On an 18 main pattern after pulling #7 skip over to #9. Increase tension 4 pounds before tensioning.
4. Fill-in main #7 (on a 16 main or #8 on an 18 main) which will be the last main. Adjust tension by adding an additional 4 pounds (reference plus 4.)
5. Tie off on main #6 (16 main) or #7 (18 main).

CROSS STRINGS :

1. IMPORTANT:  Each cross string must be held under tension at least 20 seconds before clamping off.  We recommend weaving the next cross while the previous one remains under tension.
2. Start first three cross strings and tension at same tension as final mains. (+4 over reference tension)
3. After installing 3rd cross string, reduce tension 6 pounds and install the rest of the cross strings   (This will be reference – 2 lbs.)
4. After stringing 3rd last cross, loop over and weave final cross. Increase tension +6 pounds.
5. For last cross string fill in second from bottom.  Tie off on 3rd from bottom.

 Always give professional finish by straightening strings using The String Thing!

Some points to keep in mind:

1.    This presentation of the JET Method is intended for stringers using an electronic constant pull stringing machine with fixed clamps.

2.    In the quest for stringing perfection, this is not the ideal stringing machine. However, by using the JET Method conscientiously the results can be remarkably good.

3.    If you have the choice of pulling speeds, always select the slowest.

4.    Wait 5 seconds before clamping off each main and a minimum of 20 seconds before clamping each of the crosses. (weave in the following cross while the previous cross is being tensioned, this can save a lot of time).

5.    To become a competent stringer capable of giving top quality string-jobs when applying the JET Method requires many hours to learn and to practice this craft. It is necessary to control the results obtained string by string with a Stringmeter to understand where you are losing tension and where you need to improve your techniques to overcome these weaknesses in your way of working.

6.    To aim for the end results on the court for your player requires strong motivation and real passion for your profession. Without this your will to improve as a stringer and the capacity to put into question your habits in the way you have been stringing for years, you will not be able to acquire the efficiency in this craft necessary to obtain JET Method Certification. You may well improve your results for your players and that would be a very good start, it may even encourage you to continue to learn to become a much better stringer, even a craftsman. Now it’s up to you!
