Thread: Original water power grinding house of Solingen video.

Probably a combination of very high and very low pitch.
The low pitch from the water wheel, transmission and the wobble of the big stones.
The high pitch from the knives against the stone.

There were some amazing looking grinding and buffing wheels there!
Obviously skilled professionals as they all had all their fingers despite the belt changes on moving wheels.

Skilled professionals for sure, and passionate about their work. Reminds me of the forger from sheffield video i posted recently as well.

Man! That was one bad-ass guy. He still had all his fingers! I bet they could not wait for that big wheel to wear true, if it ever did! Amazing video. Thanks for sharing!

I liked the one guy smoking the cigar in a holder and the other a pipe. No eyes and ears on those guys either. People worked safe without all of the apparatus demanded nowadays. Same with ironwork back in the day.

Apparently using a board to hold the work was the default method in Germany and Sheffield. I wonder if it acted as a sort of heat sink ? Great vids, thanks !

No. It's wood. The reason for the board is 2fold. Firstly, it is to have a flat backing for the blade. Otherwise you get -very- uneven grinding if you press the blade against the stone that hard. 2nd, it is to hold the blade tightly. The blade 'locks' to the board, making it easy to maneuver blade by maneuvering the board. The board is a lot easier to handle than a knife. And it's not only easier, but also safe. Because holding a blade by the blade and then pressing to a stone is a recipe for disaster. Severed fingers and all that.

The Japanese do it like this as well btw.
