Just as when you're getting started in electronics, you build a bunch of stuff that exercises electronic skills and knowledge, building fixutes for your machine tools is a great way to practice skills, and learn about your tools. The vise looks great. I've been trying to cut dovetails on my milling table for a slide positioner project, but so far have had trouble keeping the work piece from moving in the vise, which is a 0 - 90 degree tilting vise ( which I'm sure has a proper name that I don't know ) Actually, I'm using a pair of them because the workpiece is too long for one.
