I use a 3 inch "screwless" vise on my mini-mill (see picture). It is always a struggle to get the nut at the bottom to catch so the jaws can be tightened. This is especially true when the vise is clamped down so the bottom is not easily accessible. A second problem is that the jaws are so smooth. This is of course desirable in most situations. However, right now I am?trying to mill a complex shape in a piece of delrin, which is very slick and somewhat flexible. The smooth jaws just don't grip firmly, and the workpiecs pops out. I may have to drill and tap the delrin and bolt it onto a metal base. Anyway, this gives me an excuse to look for another vise that is easier to work with, about 3 to 4 inches wide. Ideally it would have interchangeable jaws included serrated ones that can grip the delrin.
Any recommendations?
