Default W. & B. Douglas, Middletown Conn. Big Sharpening Wheel, lots of Cast Iron

Need help getting it going, What rpm should it run? Stone is 26" diameter and 4" wide. Is it run in water or should there be a drip cup?

The Dalton Minnesota Threshing Show has a sharping stone that is like yours that they demonstrate. They run it in water and if you bring your knifes there they will sharpen them. My uncle always brings his jack knifes with when we go and has them sharpened , he says that they hold there edge longer on a wet grindstone.

How do they run it, by hand or motor? How fast does it run? its kinda tuff to find particulars about running the stone in water or using a drip cup to have a slurry paste while sharpening. thanks 4 any help.

All I can tell you is that it is run with a gas engine belted to a speed reduction unit then belted to the grind stone. As far as how fast it turns all I can say is that it runs fairly slow, about the same as you would run a pedal grinder. Since it is run in water it can not be run very fast or it would throw water all over the place. Hope this helps.

Engine running! Turns out its a 4 to 1 reduction, running @1250 rpm. Counting the chalk mark revolutions the wheel turns about 40 rpm.
