I have an old Craftsman floor model drill press. It has served me well for a long time. I want to get a decent vise for it. What do you guys know about good vises? Keep in mind - this isn't a milling machine, but I'd still like to have something that doesn't rock the part out of level when I tighten it. My drill press table does not have "T" slots - it has open slots in an "X" pattern, with a center hole. That limits my mounting options and makes me think I need something with a cross slide, but I've always figured the cross slide would give more slop. I know some of you guys have been exposed to good vises, and I wonder if there's anything that you would recommend, or at least, what should I stay away from? Thanks for any advice.
