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.

Advice will be much appreciated.

It's unlikely the vibration is caused by anything besides the wheels.
Often the sides of a wheel must be dressed because they are not parallel,
making one side of the wheel heavier than the other. No way it will run
without vibration if that be the case. In order to dress the sides, care
must be exercised, and a diamond point used to minimize risk of breaking the
wheel(s).


A heavy base is better.
My grinder base is an old brake drum, welded to a pipe for a riser, with a
plate welded on that the grinder is bolted to. Then the whole works was
filled with concrete. Probably weighs 150 pounds.

Very nice setup. Weight is definitely to your advantage, and the wheel is
a convenient foot rest for those long hours at the grinder!

A friend that used to run a fab shop made my base. He used two 2" square
steel tubes on 5-1/2" centers, front to back. These are welded to a base
that's 3/4" thick x 15-1/2" diameter, and a top that is made of 8" channel,
20" long. It turns out to be very rigid, much better than a single
column support. I have a wet diamond setup on one end of the motor, and an
aluminum oxide wheel on the opposite end for HSS I bolt mine to the
floor to prevent any movement. I get no vibration.
