Hi all,
I recently picked up a Sanford SG-48. It is a tiny benchtop surface grinder. Today I got a 60 grit standard grey aluminum oxide wheel for it and got to play with it. The wheel is 4" diameter and 1/2" width with a 1/2" bore.
It has a custom "chip" guard and a permanent magnet chuck. When original they were equipped with an electromagnetic chuck.
Enjoy the video.
