Turn a Dead Hard Drive into a Grinder or Sander



          

Details

Odds are you have a pile of dead hard drives lying around. Utilizing the RPM of the hard drive platter, you can create a grinder or even a sander out of a bad drive. Basically, crack it open, glue on a sanding disc (or grinding disc) , and plug it in. Check out the video tutorial above (may want to turn down your speakers).
