Pulling Tension Under or Over?

[Carolina Racquet]

Curious on the best practices of pulling tension on main strings where the string holes are inside the racquet's throat. I use a dropweight machine.

The manual shows pictures of pulling tension from the throat going over the racquet to pull tension. This is what I've always done.

I've seen some videos on YouTube showing the strings going under the racquet so I tried it and it seems that going UNDER is the most direct angle to load into the tension jaw. I actually seemed to put less stress on both frame and string.

Some other thoughts? Thanks.

I have always pulled under the frame rather than over to get to the string gripper. This minimizes extra pressure on the frame and on the string. IMO,you do not want to add an extra turn on the string by going over the frame and then back down. The additional friction could also be a problem.

I pull under the frame, plus I use an old credit card between the frame and the string. It's slippery, and the frame doesn't get scuffed.

under.... you don't lose tension to the friction of string rubbing on the frame and you don't damage the racquet's finish.

 

[banter]

Under. On top of the fact that there is less stress on the frame, it's the most direct line to the gripper.

 

[WitheringDemise]

I've always done under. Less stress on frame and most direct path to the tension head.

 

[jmverdugo]

Always under, it just makes more sense to me.

I don't necessarily think all of these under answers are correct. It may depend more on your machine. I find that with all of my machines, under or over pulls against the frame about the same. Under, sometimes, pulls the string into a bad position between the frame and the mounting bracket of the machine.

It all depends on your stringer. I have a Wise on a Gamma 6004 with the Gamma adapter. This means the pulling force is in the center of the racket. I can go under and back up to the center or over and back down to the center. What difference does it make?

If the pulling force is below the center of your racket go under if it is above go over.

Will be under from now on... Confirms my suspicions.

Curious why Klipper would show photos going over the racquet in all their pictures in the manual.

Thanks all for their feedback

Have always gone under. On the Aria, the racquet clears the control module which has the tensioner in it, so if you go over, you really need to make a serious angle downwards to get to it.

I think this says it all. However you can get the cleanest straight line pull. On my machine that is slightly below the racket.

If your tension head is below the string bed and the string goes horizontal across the racket and bends down to the tension head how do you pull straight? LMAO

It is impossible to get a straight pull on all strings.

Correction: The lowest angle of deflection.

I use an Alpha Pioneer III (drop weight) machine and my racquet is Wilson Pro Staff Hypercarbon 5.0. My previous rackets were also Wilson's with the same string pattern.
On the two holes that are 4th from the throat I have that choice: Over or under. I too have seen pictures going over so that's how I started. After a while I decided it would be better to go under and that's how I've done it for the last 15 years. On my racquet and machine, it's obvious that under is better.

Just measured my Klippermate. The tension jaw is about 5 3/4" from the metal base. The bottom mounting pad is about 1/2" higher (6 1/4" from metal base)

No question under the racquet is the straighter line to the tension jaw.

 

[dgdawg]

I would say under, as well.
I don't think I've ever seen a machine with the tensioner above the frame.
I've seen this done in a couple Club Pro Shop's and debated the practice with the stringer.
After our "debate", the stringer always pulled M's from below the frame. :shock:

Definitely under.

Haven't strung a racket since reading this thread; so, I had to go look at my machine. My LF MS200tt is set up so the gripper/jaw is practically level with the string plane. Seems to me that going 'under' would tend to 'lift' the frame ever so slightly and put a good deal of stress on the hold-down supports at the throat of the racket; while going 'over' would 'press' the frame toward the much more substantial surface of the mounting towers.

Are any of you 'under' pullers using the LF machines? It appears that the string is introduced into the gripper/jaw at about 'nine o'clock', slightly less string deflection going 'under' than going 'over'; BUT, as the gripper rotates when tension is applied, the jaw moves to the 12 o'clock position which is higher, creating a much sharper angle than would result if the string went 'over' the frame.

I used a Pioneer III in the early '90s and I'm pretty sure I went over the frame. Funny how these 'semi-automatic' movements aren't crystal clear 20 years later .

With the concord system on the Stringways, you can now get a "direct pull" on all the mains so that you don't have to go over the frame. All the pulls go under because the frame tilts away from the tension jaw. Obviously there is friction on the string because it's still coming out of the grommet on a downward angle, but you don't have to worry about the frame adding to the equation. I think this is a great idea and I would think that more companies would implement this type of system for those reasons.

You're right, the Klipper manual shows the string going over the frame to the gripper jaws. I mentioned this to Dave at Klipper and he says it doesn't matter whether the string goes over or under the frame - makes no difference to the resultant tension. Personally, I always go under and I imagine most people do.
