This bench grinder from 1996 is used but still in decent condition; the wheels run true and quietly. The grinder is equipped with two different stone wheels with different grits (35 & 60); one for heavy-duty and quick material removal, one for a finer and more precise material removal that will leave a way nicer surface finish.
Maintenance
The wheels need to be "dressed" from time to time in order to produce nice straight edges and maintain stability. Apparently, it's possible to do that with nothing more than a few spring washers on a piece of threaded rod![1] We should try this before spending time and money on a more sophisticated tool.
Changing Wheels
After installing a new grinding wheel, set up a safety perimeter (let's say everyone leaves the room) and let the grinder run for five minutes. Only if that went well, without suspicious noises or visible signs of problems, should the grinder be used again.
Upgrade Ideas
For really sharp knives, we could turn an MDF wheel on the wood lathe and use that as the final "grit".
