can a 2 point mounting system deform a frame. like make it lop sided or wider?
A good two point mount will not cause a problem, if the operator mounts the racquet correctly.
What about the head Ti.Sx series? Can you guarantee no deforming?
When you string a racket it is subjected to becoming shorter and wider or longer and narrower depending on what tension you are stringing the racket and the tension difference between the mains and crosses.
If you mount it incorrectly...
Make sure the mounting posts at 12 and 6 are pulled tightly against the frame and the frame is secured firmly. Quick, easy and effective.
There are to many happy users of Neos 1000 machines. So when mounted properly it should not pose an issue.
It's not just mounting it correctly--it's stringing it correctly too. Head rackets can deform even on a good 6-point machine. The machine may hold it in place while being strung, but if its going to deform, it will still do so as soon as the racket is taken off the machine. There are steps you can take to avert the deformation. You just have to know what you're doing.
Can you expand on this? What suggestions do you have to minimize distortion on flimsy head racquets?
For starters. When you string your mains, don't go more than 2 or 3 per side before going back to the other side.
I know a guy who strings his mains from one side of the racquet to the other, using just one clamp. This practice is definitely not good for the racquet.
I'm pretty sure my racquets are mounted correctly and I have a 2 point and it shortens by about 1/8 of an inch. Any help?
There are a number of things you can do:
1. You can stretch the racket a little. How much shorter does your racket get? Stretch it approx. that much. If you have screw knobs to move your 6 and 12 o'clock frame supports out, move them out a little past firm.
2. String the crosses about 4-5# tighter than the mains. That will usually pull the sides in enough to regain the original length.
3. You can make an adjustable mounting arm support. Go to Home Depot or someplace like that and get a metal arm that can lengthen when you unscrew it. Make 2 flat "eye" bolts, one for each end. After the racket is placed on the machine, slip the rod over the racket with they eye bolts between the racket and hold down clamps. This prevents the mounting arms from flexing inward. Some company used to make these, but I haven't seen one for awhile, so I guess you'd have to make your own.
I've been using an 18" digital caliper to measure growth/shrinkage on the last ten racquets I've strung. The width of the racquets increase by .082-.154. The length shrinks from .101-.153. This is all with equallly tensioned mains and crosses.
I like your idea of prestretching to compensate for this distortion.
i deformed a light frame racquet big time once by adding an extra 10 lbs to the mains than the crosses, i was able to fix some what by restringing it and not exeding the 5lb limit i set for myself from now on
the deformation happened after i took the racquet off the 2 point mounting system, not so much right away, overnight it really pulled the racquet shape to a "round" figure
