I was concerned about the vibration issues when I decided to use that large motor. It wasn't my first choice but, I got sick & tired of searching for "the perfect motor" and just went with that big one. Amazingly, the grind quality out of the one I have is really awesome... Yes, I can feel a bit of vibration when I put my hand on the motor but, it's not very noticeable on the grinder head. I think the saving grace was the heavy aluminum support strut/brace. Aluminum was intentionally used for all the external chassis parts because, it's second only to cast iron in terms of absorbing vibration. -Lucky guess on my part.
I have looked at surface ground shafts under high magnification and it looks really, really nice. I cannot see any artifacts of vibration.
It really would be nice to find a better motor some day but, the one I have will be used until a more suitable one comes along.
BTW: I was thinking of "mass producing" those grinder heads and selling them here on the Classified section. I'll need to check into the "legalities" of that but, the idea is that a good donation from the proceeds would be given to this place to keep it running. Let me know if anyone might be interested in seeing the unit I made in the classified section...
