Just to alert everyone to a freak problem we had with a Kurt type vise. The problem happened with an MSC Kurt look-alike vise. A coworker wasputting some flats on both sides of some .125 pins. But then some of the pins' flats were off center even after being indicated in. So we put an indicator on the back jaw (a custom made one) and saw that when the vise was tightened the indicator moved some .005. Then we put the indicator on the back of the immovable jaw support (at least theoretically immovable). And IT MOVED .005 when the vise was tightened. The vise was taken off the machine and the solid support was taken off the base and all surfaces and the key and keyway were cleaned, deburred and reassembled. It STILL moved when tightened. Now I'm not saying this couldn't happen to a real Kurt, but it DID happen to non-Kurt vise.
