Blackstone grading

[Rossy66]

I did a search for the answer to my question but couldn't find one so I apologize if this is being asked before, I'm looking into buying the Blackstone wheel for my T8 but I have noticed in some YouTube videos that there can be some problems grading the wheel from course to fine as it is made of silicone carbide and was wondering if anyone else has had these problems using the grading Stone.

Select diamond plates of the coarseness you wish to use for said grading.  The Tormek stone grade supposedly can be used, I bought a second one to dedicate for the SB stone, but it didn't seem to do anything and just got glazed (the grader).  A 1000 grit diamond plate is what I use for the SG grading, when I do any.  I think a lot of others do similar.

Thanks, so I guess my question is, would I buy two diamond plates, one to rough it up and one to smooth it out? if so, what crit would you recommend I buy. I use my SG250 but I am finding I need more cutting power and a bit more cutting speed as I am coming across a lot of damaged knives.

Rossy66,

Here is a link to the video by Knife Grinders Australia describing which diamond plates to buy and how to use them. They are inexpensive and readily available.
