Several years ago I bought the same grinder that Mac has. I am on my
second 120 grit wheel. The price is right and it works great. I also
use the Wolverine system. For grinding my fingernail bowl gouges I
have adapted the Ellsworth jig using a riser block in the Wolverine
cradle. This small block brings the pivot point to the correct height
on an 8 inch grinding wheel. Works for me.
