Hi, guys! I always buy a reel for my strings; however, I noticed that after every string job, there are too much excess and unused string from my stringer who pre-cuts the string to a desirable length.
So, are you saying that you are giving your reel to someone else who strings your racquet, and that they are cutting more off the reel than is really necessary?
I think that's what you're getting at. Correct me if I'm wrong.
Is there any technique that I can apply in pre-cutting a string that would be suitable to both 100 sq. inch head size and 93 sq. inch head size?
Yes, the "technique" would be to cut off a certain amount for the 100" frame and something less than that amount for the smaller 93" frame (this, of course, is assuming that both frames have the same pattern... 16x19, etc.)
Now... if they have different patterns, then all bets are off. For example, a 93" frame with a 18x20 pattern could possibly need even
more string than a 100" frame with a 16x18 pattern.
Everything being equal, you (or your stringer) need to cut
less for the smaller frame than the larger frame.
You (or the stringer) should've measured how much extra was left over
for each of the two frames, at the end of the stringing process.
Subract the "extra" amount from the amount originally cut off the reel.
That then tells you the exact amount you will actually need, the next time
that frame is strung - with
that particular string.
Get the idea?
