I was stringing a racket tonight and when pulling tension on one of the mains the string completely snapped at what looked like to be the top of the main that I was pulling tension on. I was using RAB Enduro Feel I went on to string the racket no problems with some different string (some natural gut in fact). Can anyone tell me why it broke? Or possible reason why it could break? I'm just a bit confused really, as I believe I was doing everything correctly. p.s the only thing I can think of is the clamp wasn't right up to the frame as it was fouled by the other clamp.
