Crosses tension is very low?

So I've strung dozens of my own racquets the past year or 2 on my drop weight gamma x2 and I will begin stringing for some friends in the future. For some reason for the past few months I've been having a huge problem with the crosses not being the tension set. I string solinco revolution at 53/52 and the crosses feel much looser than what they should be and feel the worst kind of mushy feeling. I believe my clamps are clamping tight enough and even times they indent the strings. Im extremely lost and don't know what's going on! I've scoured these forums to find the problem but to no avail. Thinking it was the clamps and reading how plastic gamma clamps can be a bit shotty, I've bought new stringway clamps, which didn't help much. Ive cleaned the clamps thoroughly with alcohol many times but that didn't make much of a difference either. I don't believe I subconsciously changed my stringing method and I don't believe the knots are the problem either. From the get go of tensioning the crosses they feel slack and don't move back to place and there seems to be a lot of draw back when clamping off. I even straighten the crosses. Anyone who has ran into this problem or knows a few solutions PLEASE HELP!

I've also read but don't understand much about how there is more friction on the crosses when stringing so they are always lower? But a few months before this problem arised, I did not have a problem with it. ive felt a major lack in spin and control as a result of this problem.

I have a similar issue with my stringer. I add 6 pounds of tension for tie offs on the crosses and even string a half pound higher. Do you have floating clamps? Because my fixed clamps are always at an angle to the racket for the crosses, the clamp "retreats" when I release tension more so than on the mains. The clamp stand is in line with the string so there is almost no clamp movement when I release tension. I hope that makes sense? So I have to really make sure that I clamp as close as possible to the edge (which is at the expense of moving the mains with the clamp teeth).

I much prefer crosses being the same or even tighter than looser. More control and I feel like their is more spin. Possibly because tighter crosses means that the racket elongates more, making the mains tighter?

A few of the points are hard to explain but I will try if you don't understand.

Maybe it is not the cross but the mains that are lose causing your problem. How long is your racket when you finish stringing it? You may want to call Gamma Sports and talk with John (@Gamma Tech) to see if he has any solutions.

Are you keeping you cross strings straight when you tension?
If you wait till later, they will be looser, and that amount will vary depending how much curvature of the string there is.
Since you use a drop weight, you can check that the cross string tensioned is straight while tensioned I typically push the cross string against the previous cross just before tensioning so it pulls relatively straight, then be sure aligned straight before it is clamped and tension released.
I am not saying this is your problem, as is speculation without watching you string or video of you stringing, but it is somewhere to look into.

Another thing I just thought of, flying clamps have a fixed radius for gripping the string and when you clamp your strings the last tensioned string will tend to draw back after you remove the tensioner. This happens less if you use a Stringway Triple clamp. Then you move on to the next cross, you apply tension so that your tension arm is level, now you move the clamp. What happens at this point is the tension arm drops as the strings straighten, and if you dont straighten the strings at this time (as @jim e suggests) you have more tension loss when you do. You may want to get that tension bar level again before you clamp your string and remove the tensioner. All this pulling and re-adjusting of the tension though may increase your cross tension because you your stretching a straight string longer than you did before so you may have to dial down the tension to adjust for it.

You did not have a problem before but now you do.

Did you change anything?
Are you using a new string?
Are you using a new stringing technique?

I am using floating clamps and there seems to be drawback but I'm pretty sure that happens for all floating clamps. I'll try increasing the crosses tension thanks!!!

I do straightening them as I go. Perhaps I should put more effort into it but it still seems slack after I clamp it off

That is correct. I am trying to figure out what I did before. I don't think I changed anything but I'll watch some vids online to get more info.

I did change string, I went from Genesis spin X 17g to solinco revolution recently. However it was already happening with the spin X before so I may have to just take the advice from this thread and put it to use.

S2S friction maybe causing the too low tension in your crosses.

Everytime I string each cross, I wiggle the cross while it is still under tension.
When I do this, I notice that the bar drops significantly from its level position.
This drop maybe 5-10 lbs.
This is particularly pronounced for high friction strings.

Good luck.
It is interesting to know what is causing it because I also use a DW tensioner.

when you clamp the tensioned string, and release the weight, you will get drawback. But do you see the clamp "go back" when the next cross-string is tensioned?

True it will go back almost all the way when you tension the next string. Or will it? If it falls just a centimeter off on a racket with 20 cross you've lost a cm when you've finished. I would suggest after removing the clamp and before you clamp the next string make sure the bar is level again on a standard DW.

That may be the problem because I do not see it "go back" to its position when I tension the next string. How would I fix this?

I use a Stringway, an "automatic" dropweight. My "solution" is a bit against the rules: I "bounce" the lever a bit, to overcome the resistance caused by the mains. This is easy on a Stringway, as the lever does not have to be horizontal; in any angle the ref.tension is the same. The risk is that you have some "overshoot", and end-up with a higher tension.

This would be a problem with a lock-out, or even using an eCP, not with a drop-weight.
When you use a drop-weight, you normally keep tensioning the string at reference-tension till the lever doesn't drop. If you would retension same string, this will hardly give a difference; the "stretch" is already gone.

I don't think your know what you're talking about. Remamber we are talking about an X-2

Please elucidate why that would be fundamemtely different compared with same on a SW (SW is easier, but still a drop-weight)

A SW supposedly is an automatic DW which will continue to pull at a set tension. A LO or eCP would usually have fixed clamps and after tensioning you would not see a big drop in tension like you may on worn and or dirty flying clamps. As the flying clamps will more often than not distort the string more as the last tensioned string is not held in the same place it was tensioned at there is a good chance you could lose tension.

EDIT: There is also a good chance even though the OP does not think he is doing anything different is has picked up a lot of speed as he has gotten better. I'm not real sure who said it but I seem to remember a few people saying on the forum a fast stringer is a loose stringer. The faster you clamp off he string the more the string will relax between when you clamp it and when you move the clamp to the next string. And the bar drops lower when the clamp is moved.

This quote I have been commenting; so I do not understand your "elucidation"

If the clamp is pulled back in position it was before when you are tensioning the next string, you have recovered the tension-loss

N you just got the clamp positioned in the same point it was when the string was clamped.
 
If you're mains are solid, I'd think the clamps would be fine. Maybe take a few pictures or quick 10 second video after you clamp off a cross. Hope you get your problem solved.

Ok so I strung again and I've observed that the problem is it is only tensioning the primary cross and not the previous cross along with it. The cross that is supposed to be indirectly tensioned appears to not be moving at all from the tension put on the primary string. Does anyone know a solution? It would be greatly appreciated

So you're not pulling tension on every cross directly?

No I am. So say in the middle of stringing the crosses, I have just tensioned and clamped off cross A. Correct me if I'm wrong but as I tension cross B, cross A is supposed to be tensioned too correct? But as I tension cross B, it appears that cross A does not look like there are any effects of being indirectly tensioned once again. It just stays in its position.

Even when I start the crosses on the first cross, which is not supposed to be tensioned, it does not move or appear to be have any tension when I do the second cross

When you tension strng B you lose tension at he frame because of friction where the string bends. The the cross goes through the 16 mains and at each one of those 16 mains you loose a little more tension because of friction. Then the string makes a 180 degree turn and you lose a lot of tension due to friction again. Why would you think string A would be tensione again when there is less tension pulling on it now than there was when you tensioned it?

OP? Have you ever tried cleaning the rotational string tensioner? You do have to clean the tensioner and the clamps every few string jobs just because the surfaces tend to accumulate gunk.

As a Gamma X-2 user as well I can say that I have not had this problem. You can use a crayon and make a mark on the string you are tensioning by the clamp on the opposite side of the drop weight. This way you can see if you are having any slippage when you release the tension and the crayon easily wipes off.

And to re-emphasize what others have said is that you should take your time and really let the tension bar settle and make sure that the cross string is straight and not smiling at you. If you do have a curved cross when you straighten it you will have one more click to adjust on the ratcheting system that this stringer has.

I have been using this stringer for a couple of years and a string job for me still takes about 50 minutes because I take my time.
