If you do want to buy badminton fixed clamps, and you own a Gamma, Alpha, Eagnas, or similar machine. I highly recommend the Prince style Dual Clamps, available from Watdon or Arfaian. (Both from Europe) For about $70 shipped.
Dual Clamp on the right. Eagnas on the Left.
Thanks Lakers4Life. Looks like the fixed clamps I have is 11.5mm from Eagnas.
