I am a new stringer(5 rackets maybe). I am using a gamma progression 602 II. When i go to tension a string, I make sure tthe bar is horizontal. but, when i remove the the flying clamp to move it onto the string i am tension and the string adjacent to it, the bar drops lower. (to make this less confusing: i remove the flying clamp and bfore i reclamp it it drops significantly). What do i do in this situation? one time, i removed the clamp and the bar dropped so far that the string snapped. do i: a: ratchet the bar back a bit and re-set it at horizontal(this has caused me some problems) b: leave it(this has broken a string during stringing) c: do what i am currently doing, and have something(such as a box) slightly under horizontal so that when the tension bar drops it is stopped.
