If you work with glass you are inevitably going to encounter sharp edges.
In this instructable I will give you an introduction to grinding.
Step 1: The Equipment
This is the grinder that is used. Water is sprayed as the object is grinded.
Step 2: Back to the Grind
As an object is grinded it is difficult to keep track of what has been smoothed and what still needs to be done. A marker is used to show what areas need more work.
Step 3: Changing the Grinding Wheel
As the object is smoothed, the wheels need to be changed to allow for finer grades of grinding.
