I've been offered a surface grinder

[Mayhem]

Thanks Tom. The table has a v way and a flat one. The saddle is upside-down in the pics, so you cannot see them. In the last pic you can see a rectangular block with several holes in it. The nut attaches to this and it, in turn, attaches to the saddle.

Any wheels I put onto any of my grinders gets the ring test. The one in that came with it will most likely end up in the bin.
