As I discovered, after a minor brain storm which should have happened
much sooner, the vacuum vise sticks fine if you wet the bottom. I use
it only for stone-setting because I can twist it every which way, and
I like to do my setting in a clean environment on my desk, rather
than my workbench. When it sticks, it’s a great little tool, plus I
can take it along to my second home in SC where I have no place to
clamp a traditional vise.
