would pulling the strings twice be better than pre stretching?

[2ndServe]

if I pulled the string then released it and pulled it again would this be better than pre stretching?

[drakulie]

No. Just different. That said, if you do this on the crosses, you will achieve a tighter string bed.

agree.... I do this on my own racquets.....

To insinuate is to suggest or hint something in an indirect way. What did you mean (insinuate) when you said, "IF YOU DO THIS ON THE CROSSES?"

EDIT: The OP asked what he thought was a simple enough question - which is better pre-stretching or double pulling. Your response was, "If you do this on the crosses you will have a tighter string bed." I assumed you were only talking about double pulling producing a tighter string bed. Was I wrong when I assumed you meant double pulling will produce a tighter string bed?

Irvin, it's enough that Drakulie explained what he means. Why do you keep insisting that your "interpretation" has any relevance?

It would help if you read the OP:

Let me make sure you understand what you said. Are you saying neither method is any better than the other but double pulling will produce a tighter string bed than pre-stretching?

I understand exactly what I said. Apparently, you don't.

Go back and read his first post and my response.

[2ndServe]

ok thx, I actually like as boardy a feel as I can get. I string kevlar mains at 70lbs and skip the outer mains like you did at one time. I'm wondering how high I can go before I stress the frame too much.

That depends on what type of stringer you have and what type of pre stretching you are doing. You could pre-stretch manually by wrapping a set of starring around a pole and pulling on the ends to remove coiling. Or you could use a pre-stretch on some electronic machines. When pulling tension two times (or more) on the string on a lock-out machine you will see a difference. If you are pulling tension two times on a true constant pull (some electronic machines are not true constant pull) you will see less of a difference if any. If you go through the process of pulling two times on a true constant pull then you will be pulling the string for a longer period of time. If using a constant pull and you increase the time you pull the string you increase the stretch. Even though the tension is the same longer pulling times produce a stiffer string bed.

I remember YULitle made a video one time that he thought showed if you pull a hard weave two time you got a lot more stretch but that is not true. If you want to test it out mark the point on your tension your gripper is at when you pull the string, then release tension but hold the gripper closed on the string so it remains in the same place, and pull tension again you will see it goes right back to where it was.

I have seen this video, but isn't the sharpie mark on the wrong place, shouldn't it be at the grommet not where the string is clamped on the tensioner. Correct me if I am mistaken, but as shown it seems the machine would not pull the second pull as far, not necessarily pull anymore string from the racquet. If one marked at the grommet and that mark was further away from the racquet after the second pull I would agree that that amount of string would have been "loose" in the racquet otherwise.

[Irvin]

I guess the best way to really answer your question is with a couple of questions. What are you trying to achieve with the double pull or pre-stretch, and what type stringer do you have?

More than likely you are correct but not for the reason you are insinuating. When you pull twice you are doing something to break the friction between the mains and crosses. When that friction is overcome more of the tension is applied to the complete cross string.

When I pull tension on a cross (using a constant pull) if first move the string I am tensioning to try to get it close to straight. It's breaks the friction between that cross and the mains. Ten I straighten the last cross I tensioned to get it as straight as I can. Then I move that string I am tensioning again. All this takes time and that extra time I use stretches the cross string for a longer period of time which produces a tighter string bed. With the mains that isn't necessary because there are no crosses in yet but a slight tug on the string you are tension could break the friction between the main and the frame again making for a tighter string bed all without rally increasing tension.

None of this is necessary with an electronic constant pull that produces a jerky (off-on-off) pull on the string which breaks the friction.

what am I insinuating other than to say, it produces a tighter string bed?

[2ndServe]

I have a lockout machine, an old alpha. But I find after one set my strings are catapulting my returns as I'm taking the ball on the rise in no man's land and coming in on the return.

Once this happens I feel like I have to check up on the returns to just get it in. So I'm looking for a super consistent string bed.

Sorry I missed you post somehow. Double pulling would offer a distinct advantage giving you a much more consistent tension that will hold for a longer period of time. Single pulling (with a lockout) would be similar to pre-stretching your string and there is a difference. Some machines like my Wise tensioner have a pre-stretch feature. All it does is pull at a higher tension and then drops back to your reference tension. When you single pull on a lockout you pull to a reference tension then it drops down to some value. Double pulling for you would produce a tighter string bed so you may want to consider than when you use that method. I would double pull the mains and crosses but primarily the mains. if you had a constant pull machine there would be less of a difference if there was any because the constant pulling is doing the subsequent pulls automatically.

EDIT: sorry we hi-jacked your thread

Please explain. How is single pulling on a lockout machine similar to pre-stretching? Oh, you just mean that it pulls to one tension & the resulting tension is a lower tension? For me, that happens when you string on any machine with any method! So, I must have missed your point.

If you do it on the mains you will have a tighter string bed too. And depending on how the pre stretch is done it may produce the tighter string bed. You're insinuating pulling twice will produce the tightest string bed.
