c.Use two wooden plates connected together with emery
cloth to form into a special-
purpose “Strong Polisher" for
polishing and its holes may let the workpiece pass through the
surface to be polished.
d.Use a sturdy wire brush stuck with abrasive material for
polishing.
Use force to pull both ends of emery cloth upward and be
sure not to pull emery cloth loosely or to wrap emery cloth around the operator's fingers or
around the workpiece.
When required to polish the ends of the workpiece, use only a very short emery cloth strip
or a sheet of emery cloth, as a very short emery cloth strip or a sheet of emery cloth will not
cause such problem as winding or wrapping.
When carrying out polishing with emery cloth, be sure not to wear gloves.
