Another machining question

That model is like one of the ones we had in tech school and it would not work on non conductive parts. IF all you do is steels, aluminum, brass etc then it should work fine, but plastics you have to cheat (read gage block that touches the vise).

Correct the jump style you have to watch for the jump, and some have a flat milled in the shaft so that they also click when they jump.
