I bought a nice Dayton pedestal grinder recently.
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.
