In this video i'm going to show you how i restored an old Air Die Grinder.

I've cleaned all parts, polished the aluminium case, turned a new connection for the compressed air on a lathe and replaced all bearings. I grinded all steel parts with sandpaper or Scotch Brite and made them black again by heating them up and cool down in olive oil.

Thank you for watching
