Work rests shall be kept adjusted closely to the wheel with a maximum opening of what inch?

• A. 1/8 inch
• B. 1/4 inch
• C. 1/16 inch
• D. 1/2 inch

Answer: (A)

Maintaining a close work rest to the wheel provides solid support for the workpiece, keeping it from being pulled into the wheel and reducing the risk of kickback or wheel damage. The allowed maximum opening is 1/8 inch, which constrains the gap enough to keep the piece supported while still letting you hold it securely. Opening the gap wider—such as 1/4 inch or 1/2 inch—significantly increases the chance that the workpiece can slip or catch on the wheel, creating a dangerous situation. A smaller gap, like 1/16 inch, would still be within the safety limit, but the specified maximum you should not exceed is 1/8 inch.
