I have just inherited a gamma 600FC stringing machine with tennis clamps. However, I want to be able to use it to string my badminton rackets. These seem to be the only clamps that will fit the machine. I am relatively new to stringing and haven't had my own machine before. Thanks http://www.atssports.com/tennis.cfm?product=3025 The badminton clamps that they sell say they do not fit the 600FC model. Does anyone else have any information about these clamps or a cheaper suggestion? 140 dollars a clamp is quite expensive. Thank you!
