To me, its main idea is to create lower tension around the edge of the
racquet to enlarge the sweet spot. At the same time, keeping the center of
racquet similiar to the current power level, so it won't be to powerful at
the center. Large sweet spot and off center shot play closer to sweet spot.
And sweet spot will not be too powerful.
My machine does not have pre-streach function, so I will just pull the
center string longer. I have follow this on my Wilson Ncode Six-One 95 (
16x18). Will see how it feels. Too bad I don't have a pair of same racquet
to compare this new tapered method to traditional method.
Has anyone done similar string job?
******************************************************
Here is our shop's secret to completing an improved string job with nearly
the same time that it takes to string using traditional techniques. We've
found these advantages:
• Less tension loss (as much as 10:1)
• More control
• More elasticity
• More first serves as winners
• More ball returns on target
• Builds player's confidence.
Mount the frame in stringing machine, attach initial clamp to first left
main. With the reference tension at 48 pounds (set on constant-pull and 15
percent pre-stretch), pull the first right main string and permit it to
continue pulling while threading the next four right side mains (try for a
constant time of 25 seconds), then clamp the first right main. Duplicate for
the other side. There will now be 10 strings in the frame, but only the 2
center mains will be tensioned. Go back to right side, pull ten-sion and
clamp the second and third mains using the same longer (25 seconds) pull
time. Go back to the left side, pull tension and clamp the sec-ond and third
mains using the same longer (25 seconds) pull time. Go back to right side,
pull tension and clamp the fourth and fifth mains using the same longer (25
seconds) pull time. Go back to the left side, pull tension and clamp the
fourth and fifth mains using the same longer (25 seconds) pull time. Now
there will be 10 tensioned strings in the frame. Install the sixth main on
each side using the same longer (25 seconds) pull time on each. Then turn
off "pre-stretch" and install the rest of the mains strings (with no pre-
stretch) and tie off the mains.
Start installing the crosses with no pre-stretch. Tension the first cross at
30 pounds, and add 3 pounds to each cross until the sixth cross (second
cross at 33, third cross at 36, fourth cross at 39, fifth cross at 42, and
sixth cross at 45). Before installing the seventh cross, turn the pre-
stretch on to 15 per-cent. Tension the seventh cross at 45 pounds with pre-
stretch at 15 percent and permit it to continue pulling while threading the
next two crosses. Continue installing crosses at 45 pounds with 15 percent
pre-stretch and 25-second pull times until there are six more crosses to be
done. Then, turn off the pre-stretch and install the last six mains using
the same tensions used to start the crosses (sixth-to-last cross at 45,
fifth-to-last cross at 42, fourth-to-last cross at 39, third-to-last at 36,
second-to-last at 33, and last cross at 30). Tie off the last cross and the
job is finished! The tensions I've suggested are designed for a player who
has been stringing their racquets at 60 pounds with no pre-stretch on a
constant-pull machine. The tensions can be ad- justed up or down for players
who are used to higher or lower tensions.I encourage everyone to get two
similar racquets. String one using traditional techniques and the other
using my technique, and make your own decision.
