I have just started stringing on a simple Gamma progression 220 machine and have a few questions that puzzles me:
1) The machine leave small marks on the inside of the frame, where the threaded mounting bolt meets the frame. Is this normal? I think it is more cosmetic, than worrying... I am not mounting the racket pressuring the bars outside towards the frame, but when the mains are tensioned, I guess this squeeze the frame against the mounting bars. But I guess leaving marks then either I am doing something wrong, or the machine is designed poorly?
2) Trying to avoid a double pull when having only 2 flying clamps, I use the very nice method from Yulitle:
My challenge here is that the flying clamp positioned *outside* the frame as instructed, SLIPS when this clamp is the only one holding pressure. I do insert a piece of string in the empty jaw, so the clamp should clamp like when it is mounted inside the frame the usual way. How come the flying clamp slips, but only slips in this position/used this way? I adjust my clamps so I need a little/moderate pressure to close the clamp. The clamps never slips when mounted the usual way inside the frame....
3) In search for a nice string with a little better durability than Wilson Sensation, I tried the Technifiber, syn gut. During warm up the other day first time using the racket, the string broke in the very top. I have never had a string break here before. Have I done something wrong in the stringing, that can cause this type of break? See photo link. I use 2 piece stringing and a rather normal 25/24 kg tensions.
My racket is a brand new Wilson Prostaff, so I would not suspect the racket/grommet.
Thank you very much for helping me out ;-)
