Hapstone silicon carbide powder set for stones leveling + mirrors

Through use, your Sharpening Stones will show signs of wear. They may lose their flatness after a time. The Silicon carbide Hapstone leveling is used to restore your stones to their original flatness, keeping them in prime condition.

To use, sprinkle about a ½ teaspoon of the silicon carbide on the glass or a mirror, and add a little water. By rubbing the stone against the abrasive grit, you will grind the high spots of the stone down until it is level again.

set consists of 5 grit types of silicon carbide 

•  80 grit (200/160 mkm)
  
•  120 grit (125/100 mkm)
  
• 280 grit  (60/40mkm)
  
•  500 grit  (14/10mkm)
  
• 1000 grit (5/3mkm)
  

+ 5 pieces of mirrors with high quality rubber feet to prevent slipping during leveling.

• The mirrors have the dimensions 200х200х4мм
• Mirror sanded on the sides to avoid injuries

Take a slate pencil and put crosshatch pattern to the surface of the stone. Never skip this step. Your goal is to get rid of crosshatch completely. If you notice left-over of pattern somewhere, it means geometry is not flat yet.

Always add water to make a suspension, not dry SiC. Try to use glass area evenly. Your glass will wear over time because SiC affects glass too.

For hard stones, coarse SiC will be the major time consumer. When SiC disintegrates, put another pinch (refresh). If there is too much suspension, clean your glass. Use a straight edge or metal ruler to check flatness. If you are not sure, make crosshatch pattern again.

The abrasive hygiene should be a priority. Don't let single coarse particle to remain in fine lapping.
