Hi I'm Kristi.  I want to talk to you today about the Hatho minimat kit. You're going to get a kit, it's got three different grits from fine to coarse. It comes from 30 millimeter all the way to 60 millimeter.  This product has patented curvature pins that you want to load on this little wheel in the direction of the arrow shown.  Then you're gonna mount it onto your mandrel.

Now I'm going to demonstrate how this wheel really works. I'm going to take a ring here, and very important, make sure you have safety glasses on.   There you go.
