String moving out of position very quickly

Hi guys,

I've struggled with this problem for a long time. I thought it was because of my thin string which I was putting on my Clash 100 - Hyper G 1.15 - the string (mains) started not to go back on its position after ~6 hours (even though I'm not a hard hitter). Recently I've bought another reel of string, but this time Tourna Big Hitter Silver 7 Tour 1.25, but it also tends to getting out of position and not going back after 6-8 hours. The problem is that even in the first hour/two hours it likes not going back on its position (even the crosses).
Is it maybe because of the low tension I put on? I string my Clash 100 at 19-21 kg.
I also have a question what technique you use to straighten the crosses while stringing, or maybe you straighten it after stringing?

Lower tension will reduce the strings returning to center. The gauge and strings tension maintenance will also affect how long tension is held before it won't return. Different strings have different friction coefficients which can also affect how well they return to center. As the strings wear notching will occur which also reduces their movement.

I apply pressure to the crosses towards to the head of racket as I pull tension on the crosses to help reduce friction and keep the strings straight. After I string the racket I straighten any mains and crosses by hand.

For CP. weave and pull ref tension. Move the cross down and back up until straight. This removes a lot the friction between mains and cross, which keeps you from achieving ref tension on cross. Now clamp. With a DW, you will see the bar dip. With eCP, the machine will adjust.

For LO, strighten the string before you pull ref tension. Crank and clamp OR crank 2x and clamp. The SBS of the stringjob will be lower than one from a CP machine.

Anything under 1.20mm is not going to maintain tension very well. The cross section is just too thin. 1.25 is better. 1.30mm is good. Ball impacts permanently deform polyester strings. If they are prestretched, then it will take much harder ball impacts to make the strings lose tension. And your ref tension is not the issue. 42-46# is reasonable for polyester strings.

I’m using a drop weight. So do you mean that when I string a cross, I should move it to bottom and top and when the bar drops, I SHOULDN’T pull the tension again?

Re-Level the bar after "excercising" the cross up and down abit to break the friction. If you have a ratchet, just hold the drum in place and ratchet up a notch, etc.
