We got this old bench grinder used but still in good condition; the wheels run true and quietly. The grinder is equipped with two different stone wheels with different grits; 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.
Take care: there is no prevention of turning on after loss & restoration of power (keine Anlaufsicherung)! Besides, the motor takes quite a long time to run down after it was turned off.
This tool is not ready for use yet since not all commissioning steps have been completed. The process is not yet tracked on GitHub. Feel free to contribute to making it usable, any help is very welcome!

Specs
- wheel diameter: 6" (approx. 15 cm)
- motor: 1/2 hp
- speed: 2950 rpm
- serial number: 898853
Maintenance
The wheels need to be "dressed" from time to time in order to produce nice straight edges and maintain stability. There is a T-shaped diamond file for this on the grinding table.
Apparently, it's also possible to dress a stone with nothing more than a few spring washers on a piece of threaded rod![1]
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.
