Cross and Main tension
Sorry to ask but what does main and cross Stringing Tension refers to ?
I've seen MP33 having :
- Main:16-18 lbs(7-8 kg)
- Cross:18-20 lbs(8-9 kg)

- Main:16-18 lbs(7-8 g)
- Cross:18-20 lbs(8-9 g)
Its gram, not kg i think, if kg, it will be super heavy?
the higher the tension, the heaviler it is?

Sometimes I wonder if the full 10% more tension on the cross is justified when the requested tension is 30 lbs and more. Do other stringers with constant-pull machines notice the following?
The frame warps slightly perpendicular to the axis of the shaft. I do not know how to explain this but imagine your hand is strong enough to apply a torque to the frame and the shaft is the axis of rotation and twist the frame. Width wise, the frame is perfectly fine - the frame is not narrowed in or bulged out.
So far I notice 28 lbs is about the maximum tension a Ti-10 can handle without having its frame warped in such a manner.

Laserfibre drop-weight MS-200 TT, five internal points of support and three clamp downs.

imagine the string. 1 end tied around a ring in the ceiling. on teh other end you knot 10 kg of weight. the tension you fell on the string is the same as when you tension that string inside your racket at 10 kg)
IT DOESN'T mean you have 10 kg of string in you racket....

The design of the MS-200 TT is such that the throat end is elevated with the badminton adaptors attached and the racquet mounted. So, this may explain the warping, but we need stringers with six-point suspension or clamp down constant-pull machines to do testing first.

It shouldn't happen. Most high end racquets have to pass the torsion twist test at the factory. Maybe a manufacturing defect or maybe the racquet is getting old and getting racquet fatigue! Does the frame stay flat if you place it on a flat surface?

Don't know about manufacturing defect. The racquets were brand new 2004 production batches when I got them. Yeah, the frame stays flat, but I do notice a tiny bit of twist. I just don't know. Maybe the human eyes and hands go funny .

i have a little thought, since most modern racquets can take up to 30lbs then why should you worry about the 10% tension rule, correct me if im wrong but, that 10% more on the cross doesn't help much does it?
