CARE
OF GRINDING
WHEELS
In normal
usage grinding
wheels
may become
grooved,
out of true, and become
"loaded."
Loaded
simply
means
that soft
metals
or other
materials
have filled
up the pores of the wheel.
When
this occurs,
grinding
action
is greatly
reduced.
Grinding
of soft metals
such as aluminum,
brass, copper,
lead and the like should
be avoided
as much as possible.
When any of the above con-
ditions
occur, the wheel
may be put in good condition
again by "dressing
the wheel."
Various tools
and abrasive
sticks
are available
in most hardware
stores
for this purpose.
To "dress"
the wheel,
start the Wet Sharp Machine
and work the dressing
stone back and forth across the wheel until all
grooves,
etc., are gone.
Be sure to use suitable
eye protection
for this purpose.
Dressing
stones
are available
at most hardware
stores
or may be ordered
through
Sears. See optional
equipment
in parts list.
IMPORTANT: Clean wiper after dressing wheel.
