Newbie questions about the Stone Grader SP-650

[Stickan]

Hi,

The grid in the stonegrader and the SB-250 are close in hardness. The grid in the stonegrader is larger and bound harder.
A trick is to use the stonegraders edge and use more pressure than on the SG stones.
Then you will remove more binding material and the stone becomes active.

Thanks, Stig.

I will put your advice to use in my new on order stone grader. I do believe the SB-250 is generally not well understood on the forum.

Hi Stig,

thank you for the explanation. That explains the "polishing" of the grader after using it on the SB stone in a standard pattern, that means more or less flat.
