I have a woodworking friend who's bought a good grinder for sharpening
turning tools. She's mounted it on a regular metal post-style grinder base,
but it vibrates a lot. Is there a better base that would minimize this? She
has a wheel balancing kit but believes that it's the whole base that's
vibrating, not just the wheels.

The base may have a resonant mode right where the grinder's vibration is.
Add or subtract weight to it. Or reduce the vibration amplitude (i.e. by
balancing the wheels). Running the grinder without the wheels is a real
good place to start. Guys whose drill presses vibrate sometimes fill the
column with sand and then oil, or even concrete, or clamp the column to a wall.

Lay a 25lb bag pf #7 1/2 bird shot on top of the grinder. If there are
vibration issues, this will deaden them, and one can use the same bag
to diagnose where the problem is coming from.
