I think such a tool is essential for every stringer because it checks the end result of your stringing job but it also checks if your machine is still working well.
It also tells you if a string keeps the tension well, if strings with too much remaining elongation are used the SBS can go down by 15 to 20 %. So if a customer complains about his stringbed it is very easy to determine if he needs a new string.
I once read this saying: A stringer without a stiffness tester is like a carpenter without a ruler.
I use the Stringway version of the ERT300 called the Stringlab.
Because these tools do quite a complicated job, they are also sensitive to how you use them:
- You have to place it in the centre of the stringbed where the bed vibrates maximum. The tool can not function where the stringbed does not vibrate enough.
- You have to hold the racquet always at the end of the grip, so that it hangs as free as possible.
What kind of difference did you get during the 10 tries?
I agree, an accurate tool like this could be of real value.
I understand you didn't say this but, I don't know if I necessarly agree with the comment:
A stringer without a stiffness tester is like a carpenter without a ruler, but I get the analogy
I'm thinking I need to learn how to use it.
So, this could possibly be the answer to the question I get all the time: "is their a way to check the tension of a frame after it's strung?".
My response is: Not without a really expensive Bab or Prince RDC.
This just goes to show you, you learn something new every day!!
Technatic: thanks for mentioning Stringlab. I'll be looking at that too.
The disparities I got were big. This is why I ask this ? here. I knew I'll get answers from experienced users.
Not that I agree with everything I read here, you've said to me before, and I wholeheartedly agree, it's healthy discussion. More knowledge is only a good thing!!!
I won't use exact #'s I was getting, I can't remember what the exact #'s were, but I will say they were all over the place.
I'm sure it was operator error
