Crack while Stringing

**silentheart** · 06-06-2005, 01:17 PM

Did you tighten the bolts where the vertical holding bars connect to the turn bar? It might have sliped. Also, was the pad thick unough that it is almost level to the holding mount? Could you give us the machine brand and model number? We might help you more if we know which one you use.

It could have 1,000 possibilities, and the common ones could be:

1. The racket is a fake one, which is bad in quality to start with.

2. The racket is already damaged due to possible manufacture defect, mis-handling / storage / shipping, clashes, etc.

3. The racket was not mounted (tightened) properly.

4. The tension is way beyond the max rec. tension.

5. Mis-usage of string machine / tools during the process, etc.

EAGNAS FLEX 920 When you say tighten the bolts is it the top and bottom one and the four corners. I was told not to tighten them too much but just tighten them so there nicely snugged in. Or is it tighten it so the racquet cannot move when i pull it. And the other thing is im not sure if the tension is really correct what it says on the machine.

Sorry, I was replying noiso4me's question.

Regarding the eagnas flex 920 machine, it is a hand crank machine. For hand crank machine, you need to calibrate the tension once a while. I splke to eagnas about this before and he (Victor?) told me that a new machine could be off by +- 5 lb. He told me to get a calibrator if I get any hand crank machine. I use tension calibrator to test my electric machine every 6 month. (just for a peace of mind) For drop weight machine, you verify it the first time and it is good for the life time of the machine. I use to take the drop weight machine to lab to have some fun with the students to see if they can calibrate the machine with items in the lab...

What was the tension that the 800 OFF was subjected to?

well on the machine said 18lbs but it was not for sure.

I don't think it's an over tension issue then . . . better check with the calibrator anyway.

I don't think it was the fault of the machine. More likely, it is the operator who is at fault. Was the crack on the inside or outside of the frame?

Unless it's manufacture defect or fake racket, it seems like maybe the racket is over tighten when being mounted.

it was in then the crack expand a little out.

I don't understand when you say, "it was in then the crack expand a little out." Do you mean there was a crack before it [the racquet] was in [sitting in the machine]? Or do you mean the crack immediately appeared right after the racquet was placed into the machine? It seems imposible to tell what went wrong without actually seeing your machine and your racquet.
