I bought a nice Dayton pedestal grinder recently.

It is 3/4 HP, 8 inch wheel diameter, 7 amps IIRC, and has a dust
collector in the back, which is why I liked it so much -- less dust
makes for a better life. So if all goes well, I will replace my 1/2 HP
Baldor with it.

HOWEVER, this Dayton grinder vibrates. Not too much, but the Baldor
does not vibrate at all, so this stands out. I can and will check the
spindle with a dial indicator, but by looking at wheels, the spindle
does not seem to be too bent, the wheels are not wobbly etc. All in
all, the vibration is very noticeable, but not too bad. I think
that what causes the vibration is a minute imbalance of wheels.

I read a little bit about "bench grinder vibration" and it seems that
the recommended course of action is to dress the wheels. So my plan,
for now, is to take a diamond wheel dressing stick and to try to dress
it flat. I am not sure, at this point, how exactly to ensure that the
wheel is square after dressing. Any tips from those who did this, will
me much appreciated.


You can dress a wheel like this with a 1" Carborundum stick. They are about
six inches long.
The better method is a wheel dresser that has a half dozen rotating wheels
mounted in a metal "handle".
