What is the proper procedure for setting up the center jaw on a dualstation vise. There is naturally a very small amount of slop too allow for the pins to fit properly so what I'm doing is pushing it a bit to take out the slop then tighten and I'm getting good repeatability there. The thing is after tramming the vise and then swapping the center jaw to the slim Jaw its out of tram. Can anyone share their experiences.
