These include
an impregnated polishing point
and an impregnated polishing wheel for bring-
ing metal surfaces to smooth finish; a felt polish-
ing tip and felt polishing wheel, and cloth
polishing wheel, all used for polishing plastics,
metals, jewelry small parts. Also included in
this group is a polishing compound (No. 421)
for use with the felt and cloth polishers.
Polishing points make a very smooth surface,
but a high luster is obtained using felt or cloth
wheels and polishing compound.

Sanding Accessories
Sanding discs in fine, medium, and coarse
grades are made to fit mandrel No. 402. They
can be used for nearly any small sanding job
you might have, from model making to fine furni-
ture finishing. In addition, there is the drum
sander, a tiny drum which fits into the Moto- Tool

fiberglass, sand inside curves and other dif-
ficult places, and other sanding jobs. You
replace the sanding bands on the drum as they
become worn and lose their grit. Bands come
in fine and coarse grades.

Wire Brushes
Three different shapes of wire brushes are
available. For best
results
wire
brushes
should be used at speeds not greater than
15,000 RPM. They remove rust from tools and
other metal surfaces, and clean and burnish
metal parts. Use for such jobs as cleaning elec-
trical connections to assure good conduction.

~
operating speed for at least
one minute before using wheel. During this
time no one Is to stand In front or In line with
the brush. For best results do not run In
excess of 15.000 R.P.M.
Bristle Brushes

are excellent cleaning tools on silver-
ware, jewelry and antiques.The three shapes
make it possible to get into tight corners and
other difficult places. Bristle brushes can be

High Speed
Cutters
Made of high quality steel. All have Va" shanks.
Can
be used
for
shaping,
hollowing
most
metals, plastics and woods.
~
When
using
steel
saws,
~
cutoff wheels, high speed
cutters or tungsten carbide cutters, always
have the work securely clamped. Never
attempt to hold the work with one hand
while using either of these accessories.
The reason Is that these wheels will grab If
they become slightly canted In the groove,
and can kickback causing loss of control
resulting In serious
Injury. Your second
hand should be used to steady and guide
the hand holding the tool. When a cutoff
wheel grabs, the wheel Itself usually breaks.
When the steel saws, high speed cutter or
tungsten carbide cutter grab, It may jump
from the groove and you could lose control
of the tool.

CURVATURE
BRUSH
OF HOUSING
CAP
With the cord unplugged, remove the brush
caps one at a time with a small screwdriver by
rotating cap counter-clockwise and check each
brush.
If the brush is less than 1/8" long and the end
surface of the brush that contacts the com-
mutator is rough and/or pitted, they should be
replaced. Check both brushes. Usually the
brushes will not wear out simultaneously. If one
brush is worn out, replace both brushes. Make
sure the brushes
are inslalled
as illustrated.
The curved surface of the brush must match the
curvature
of the commutator.
After replacing
brushes the tool should be run at
no-load;
place it on a clean surface
and run it
freely for 5 minutes before loading (or using) the
tool. This will allow the brushes
to "seat" pro.
perly and will give you more hours of life from
each set of brushes.
This will also extend the
total life of your tool since the commutator
sur-
face will "wear" longer.
