Hey guys I have been lurking around on and off for a few years newer really had the time to get around building any machine.

Now I need to build a testing device form my PhD project. What I need is a controlled motion in one axis, the necessary movement is no more than 1-2" and I need two speeds. I'm going to do durability tests by repeatedly stretch and unstretch sealant rubber glues and do some stress tests on stucco.

My idea is to buy a machine vise and add a stepper or servo motor with necessary computer control, hence similar to a z-axis setup. Do you think this is a good idea or do you experienced guys have any pointers for me.

I need help with everything because I don't know where to start.
