I'm curious though: why *can't* you keep the "darned magnet turned on all
the time" (except when moving/repositioning the base, of course)? It's not
as if the magnet will wear out or lose strength. You suggested turning the
magnet half-on, so it appears as if you are still placing it on a magnetic
surface. Perhaps you'll find the answer you're seeking if you were to
explain the actual problem that you're having.

Ok, I'm sliding it around on my table and it stands up because it is
pressing on the workpiece, then I set it aside and forget that the
contact pressure was keeping it upright, and it falls over. Maybe if I
could turn the magnet "half on" a metal surface would keep it upright
and still allow you to slide it. But not on a wooden bench or surface
plate. The larger dials make balance even worse and can be annoying to
use on a surface plate. Are lead bases perhaps used on surface plates?
