STEP 4. These photographs show the process of removing the edge. Using whatever tool is
selected, work the tool around the wheel’s circumference removing only enough material to
eliminate the sharp edge. This should only be a small amount of metal. Perform this work on
both flanges if there is evidence of sharpness.
Regardless of the method which you choose, the objective is to remove only the sharp edge
(photo 9). Remove just enough metal to smooth the edge. Take care to make sure the edge
removal is as uniform as possible. Avoid gouging the wheel.

CAUTION
Removing sharp edges with hand or power tools produces metal
filings and sparks. Many power tools have edges that are sharp or may
become hot during use. Some power tools produce excessive noise when
used.
Metal filings can be sharp and, when projected by the action
of power tools, can cause serious skin or eye damage. Excessive noise
from power tools can harm hearing. Sharp edges can produce cuts and
hot surfaces can cause burns. Cuts and burns can lead to infection.
Always wear appropriate safety gear such as protective eye wear, gloves,
protective clothing and hearing protection when using hand or power
tools.
CAUTION
!
Die Grinder. Used with a sanding wheel, cutting stone or grinding tool, this is a version
of an electric grinder. This tool is very quick and effective as well, and care must be taken
to remove metal as uniformly as possible and not to gouge the wheel (photo 7 on previous
page).
