Hi all

For those who thinks DIY Surface Grinder too expensive or too
dangerous to make due to the high speed involved, you may consider
using a safe and slow way using an oil stones just like sharpening
knives. It works fine but slow. Am in the midst of looking for a
suitable oil stone, encountered few fakes Carborundum-Indian Chief
head logo, must have been China made.
