So heres my story, I started stringing rackets last year and everything was going smoothly until a few months ago where I frequently break rackets during a stringing job. They all break at the 4/8 o clock area when I get to the bottom half of the cross. I make sure that the supports are snug (not tight) when setting the racket up and I tighten them when they get loose during the cross. What is going on here!?!?!? p.s. Some rackets are older so I understand that they may have existing damage but I broke a brand new racket the other day so I have no idea what is going on.
