Tension

String Tension – Actual vs. Reference

In the world of racquet stringing there are a multitude of debatable subjects that always stir more interest than others. One such subject is that of string tension. A player may know what he wants in the racquet based on what was done last time. But what happens when that player takes his racquet somewhere else for service? If they asked for 60 lbs on their last visit, are they going to get the same results this time? Experienced stringers know exactly what to do in a situation like this and you might be surprised to learn just how easy it is to handle. Since there are differences in machines and stringer technique, these two factors alone are going to play a key role. Other factors are at work and should be considered as well.

Your primary focus is consistency. If you’re customer is a repeat client and he/she was satisfied with what you did last time, your goal is to duplicate those results. This means keeping accurate records of your work. Make your own charts, include whatever data you deem necessary, but the key is to have a baseline for reference.
Assuming that you’re using the same string/racquet combination the process is relatively easy. However, the duplication comes from the simple things that the player never sees. Make sure that your clamps are clean and adjusted properly, your machine is calibrated on a regular basis, and you have a means to measure string bed deflection immediately after the racquet comes off of the stringing machine. What device you choose to use is up to you as long as you’re using the same thing each time.
Much emphasis needs to be placed on the above. To achieve consistency you must have a process that can be duplicated. Debate about what device is best to measure string tension is a mute point. You’re goal is to do one thing and that’s to satisfy your customer. Ultimately they will have the last word and if they’re not happy you have work to do.
One word of caution may be advisable here. In many cases you’re going to find that your reference tension and the actual tension measured after the racquet is complete will not be the same. As a competent stringer you understand these variations but your customer may not. Therefore, it’s best to use these results for the consistency you seek, not for debate with your customers as to why the two figures are not the same. If they requested 60 lbs and your test device measures 64 or 56 they’re going to question this-guaranteed! Use your test results for a your own internal baseline measurements and nothing more and you’ll save yourself a lot of headaches with irrelevant debates.
In summary keep these points in mind. Your number one goal is to satisfy the player you’re stringing for. Keep good records, maintain your equipment, and communicate with your players to get the information needed to do a good job. Quality work and good record keeping is your key to consistency. Your reward is the repeat business you earn from loyal customers who appreciate your work!
