Bench Grinder 21162 - Hesitated to buy it... but now I love it!
I hesitated to buy this Grinder, based on comments in some of the reviews here regarding vibration. After thinking about it for a couple of weeks, I decided to give it a try when I saw it on sale (internet only) for $137.99. I ordered it online with store-pickup, and got it the same day.
The first day I turned it on (not bolted down) and it had a noticeable vibration, even at slow speed. The next day after taking time to bolt it down (and removing/replacing the grinding stone and wire wheel in the process) the vibration seemed much much worse. Upon inspection, I found that the grinding stone now had a side-to-side shimmy (wobble) of about 1/8", even though it was firmly attached to the shaft. Not good, not good at all.
I decided that it had to be related to the fact that I had removed and replaced the grinding wheel. The solution turned out to be very simple. I unplugged the Grinder and loosened the grinding stone just enough so that I could turn the Grinder shaft by hand (by rotating the wire wheel) while holding the grinding stone stationary. I adjusted the grinding stone position (in relation to the shaft) a little bit at a time, then spinning the shaft/stone combination slowly by hand while observing the side-to-side motion in between each adjustment. I found a position that gave very minimal (almost none) side-to-side wobble, and tightened up the locking nut. Powering up the Grinder, it was now (almost) silky smooth. The only (very very minimal) vibration remaining is probably due to a small egg-shape (offset) in the wire wheel. But I will be replacing the wire wheel with a cotton buffing wheel in a few days anyway . . .
This Grinder seems to have plenty of power for the home user. After having been apprehensive about buying it, I'm now really very happy with it.

I didn't use it much, but was surprised at how much it vibrated.When I added a wolverine sharpening jig I found I couldn't even true the wheels.Horrible machine; don't buy it at any price.
