On the current version, the screw is in the obvious location. On yours, those screws should to something w the pipe jaws.l have an import one of those vises, do l loosen these "gib screw" looking screws to lean it sideways?

I wonder if they counted on the main screw locking it down, so you can't keep it tight and rotate the vise? No idea. Is there anything on the back end of yours, near where the slide hangs out.?
