I bought a Flex 940 with the idea of adding a Wise 2086 in the near future but I'm already having problems with the clamps. Right out of the box, the clamp wheels were VERY difficult to rotate (tight?) and adjust as needed. It's been about two weeks and I'm going to send them in so their "technician" can check them. The string seems to be pushing the clamps open when I adjust it tight enough (without damaging) so it doesn't slip. (Problem seems to be the wheel's thread is worn out enough that it slips with enough pressure) I want to know if any of the other brands carry clamps that would fit the machine in case the Eagnas ones I get back are just bad If it's not common knowledge, it would help if someone could post the diameter/length of clamps from their machine. Thanks in advance.
