Hello...
I saw this tread a few days ago and decided to make my own grinder when I go home next week...
I saw this kind of wet grinder here in Croatia for some 90 kn (around 18$)...
I was thinking of leaving the water tank and gluing the strip of rubber on the stone with some kind of waterproof glue or epoxy... Then I would make rings out of wet sandpaper and slip them on the rubber...
This way the water would remove the steel particles from the sandpaper and water could also cool the steel while grinding...
I would also install something to be able to vary the motor speed...
What do you think?
Could it work that way?
Thanks...
