I have a treadle stone like that. Puts a wicked edge on axes and the like. That looks like the mother of all speed reduction boxes on yours ....Love it!!

Looks like the stone stands still and it rotates the earth underneath it!!

Has it got a sprag clutch on the stone shaft or in the gearbox?

I can't imagine the worm gear will appreciate the inertia of the wheel trying to backdrive the system when you stop the motor if not!

Terrifying. What speed does it run at? Need a bit more tha safety specs with that one..

No sprag clutch here,it turns about 60 rpm,the gear box is from a vintage clothes ringer/washer that ran on a 2 stroke gas motor way back when..

Yes it does..kept it old school and used 1/3rd of a 14 inch tire.
