This
drill press
has
been planned
to
give
you the
utmost
in
precision
and
efficiency
of
operation.
Quality material coupled with rigid
manufacturing
standards
are
maintained
to
give
you the
high stand-
ard of
quality
found
in
this tool.
The
chuck
furnished
has a
collar attached which
will
keep
it firmly
seated
on the
spindle taper
for all
operations especially
where side thrust
on the
cutting tool, such
as
routing,
might
loosen
the
chuck.
Exterior
styling
of the
head
on
this
drill
press
encloses
the
revolving mechanism
for
safety,
yet
leaves
the
belt readily accessible
for
changing
to
obtain
different
spindle
speeds.
All
features
combine
to
give
you
maximum trouble
free
service.
To
prevent damage
or
loss
in
shipment some
of
the
parts
were
disassembled
from
the
tool.
These
parts
are
listed below.

ASSEMBLY:
Place
feed
handles
on
tool
as
shown
in
Fig.
1.
Clean taper
on
spindle
and the
tapered socket
in
chuck
body.
Be
sure they
are
free
of any
particles
which
might
not
allow proper seating. Apply
a
film
of
light
oil to
both
spindle
taper
and
chuck
socket. Place chuck
on end of
spindle
and
screw
the
collar onto
the
threaded portion
of the
spindle.
Tap the
chuck body,
not
jaws,
from
below with
a
piece
of
wood
to firmly
seat
it on
spindle, then
tighten collar.
The
collar does
not
need
to be ex-
cessively tight
as it has a
tendency
to
tighten when
drill
press
is
running.
Place
the
chuck
key in the
hole provided
at
side
of
table support,
see
Fig.
1.
Keep
the
Allen wrenches
in a
handy place near
the
tool.
INSTALLATION:
Three
1
3/32 inch diameter holes
have
been
pro-
vided
in the
base
through which bolts
or
screws
may
be
inserted
to
secure
the
drill
press
to a
well con-
structed bench
or
tool
stand.
To
install motor loosen
the
motor mount
lock
screws, Fig.
1,
until
the
motor mount
may be re-
moved.
Fasten
the
motor
to the
motor mount with
the
bolts, nuts,
and
washers provided
so
that when
motor mount
is
reinstalled
on the
tool,
the
larger
portion
of the
mount will
be
down.
For
convenience,
if
your motor
has a
switch,
and
rotation
will
be
cor-
rect, place motor
on
motor mount
so
that
the
switch
is
on the
left
side. Direction
of
rotation
of the
spindle must
be
clockwise when viewed from pulley
end of
spindle.
Mount
the
motor pulley,
No. 60, on
motor
shaft
so
that
the
small diameter
is at
bottom.
For
normal
speeds,
the
largest groove
on the
motor pulley should
be in
line with
the
smallest
groove
on the
spindle
pulley,
No.
1.
Tighten
the
pulley
set
screw with
the
larger Allen
wrench,
No. 62. If
your motor
shaft
has a flat on
it,
position
the
pulley
so
that
the set
screw will
tighten
against
the flat.
Place
belt around
the
pulleys
and
tighten,
not
excessively,
by
sliding
the
motor mount away
from
tool.
Tighten
the
motor mount lock screws
to
maintain
this tension.
Adjust
the
screw,
No. 42,
until
the
center line
of
the
motor
is
parallel with
the
center line
of the
column.
MOTOR:

LUBRICATION:
The
spindle
and
pulley bearings have been packed
with
lubricant
and
will require
no
further
attention
for
the
life
of the
bearing.
Place
a few
drops
of oil
occasionally
on the
pinion
shaft,
No. 54. The oil
hole
is
located
in the hub
on
trie
right hand side
of the
head.
To
maintain smoothness
of
operation
and to
pre-
vent
rust,
occasionally apply
a
small amount
of
light
cup
grease
to the
quill
while
in a
down posi-
tion.
With
quill
still
fully
extended, reach into
the
backside
of the
head
and
apply grease
to the
spindle,
below
the
pulley,
and to the
upper portion
of the
quill.
Occasionally
wipe
the
column,
table
and
base
with
an oil
soaked
rag to
prevent rust
and
maintain
smooth
sliding action.
CONTROLS:
The
chuck
is a
key-type
and has a
capacity
of
0-1
/ 2
inch
diameter.
It is
equipped with
a
lock collar
to
retain
it on the
spindle. This eliminates
the
neces-
sity
of
having collet chucks
for
such tools that
de-
velop side thrust while
in
operation, such
as
routers.
The
feed stop
unit
provides
a
means
of
presetting
hole depths before drilling
or for
drilling several
holes
to the
same depth.
The
lock screw,
No. 36,
when
tightened,
holds
the
feed
stop collar,
No.
37,
in
place.
The two
pieces,
as an
assembly,
can be
moved
on the
stop
rod for
fast
positioning
by
turning
the
unit
a
quarter turn
and
sliding
it up or
down
to an
approximate
pr.aifir.ri,
The
feed
stop
adjusting
collar,
No. 34, can
then
be
adjusted
to the
exact depth desired.
CAUTION:
The top of the
adjusting collar should
never
be
more than
J/s"
away
from
the
shoulder
of
the
feed
stop collar
after
an
adjustment
has
been
made.
If the
desired
adjustment
can not be
made
within
the
J/g"
allowance, reposition
the
unit
and
adjust
the
feed
stop
adjusting
collar.
The
feed stop
rod is a
gauge, with
5
inches
of
1/16
inch graduations, carrying
the
feed
stop
and
lock nut.
The
feed handle
is
used
to
raise
and
lower
the
chuck
4
inches.
It has an
automatic spring loaded
return
action.
The
quill lock handle when tight holds
the
quill
at any
depth
of cut for
such operations
as
shaping,
routing,
surface
grinding, etc. Always release
the
quill
lock before changing position
of
quill.
The
table
lock handle
and
headstock lock handle
control
the
barrel locks which grip
the
column.
When releasing either
of
these handles
do so
with
care.
Support
the
part
you
wish
to
adjust
so
that
it
will
not
drop
too
rapidly causing damage
to the
tool.
The
feed return adjusting knob controls
the
spring
tension
on the
feed
lever.
The
motor
mount
has
been hinged
in
order
to
make
the
changing
of
spindle
speeds
easier.
The
hinge
action incorporated
in
this motor mount
will
allow quicker belt changes.
To
move
the
belt
from
one
pulley groove
to
another, pivot
the
motor for-
ward
and
slip
the
belt into
the
desired
grooves.
ADJUSTMENTS:
The
following
adjustments
may be
necessary
to
keep
your
drill
press
at its
most
efficient
operation.
If
the
automatic
feed
return
fails
to
return
the
chuck
to the top of the
stroke
or if the
return action
becomes
sluggish,
the
tension
may be
adjusted
as
follows;
Lock
the
chuck
at the top of its
stroke
using
the
quill
lock handle.
Hold
the
feed return
adjusting knob
firmly
and
release
the
feed return
adjusting
knob lock screw, Fig.
1.
Turn
the
adjust-
ing
knob counter-clockwise
and
re-tighten
the
lock
screw. Release
the
quill
lock handle
and run the
chuck
down.
If
spring tension
is
still
not
sufficient
repeat
the
above
adjustment
until
it is.
FIGURE

To
change
the
locked position
of
table lock handle
or
headstock lock handle (Fig.
1 ),
remove handle
and
rotate table
lock,
item
67, or
headstock lock,
Item
5 1,
180°.
Re-insert
and
tighten lock handle.
CAUTION: Headstock
or
table assembly should
be
securely supported when changing locked position
of
handles.
The
Quill Lock Handle, (Fig.
1 ) for
greatest ease
of
operation should point
down
when locked.
To
change
the
position
of the
handle, loosen
the set
screw,
remove handle
from
hex
head screw
and ro-
tate
to
correct position. Replace handle
and
tighten
set
screw.
Belt
tension
adjustment
is
made
by
loosening
the
motor mount lock screws
and
moving
the
motor
mount
away
from
the
tool. Excessive tension short-
ens
bearing
life,
causes excessive belt wear
and
robs
the
motor
of
power. Tension should
be
just
enough
to
prevent slippage
at
normal operating
speeds
and
feeds.
Tighten pulley
set
screws
after
a few
hours
operation.
TYPES
OF
BITS:
A
variety
of
bits
are
available
for use in
your drill
press.
For
metal
drilling
the
standard twist drill will
prove adequate
for the
home
-work
shop.
If
exten-
sive
commercial operations
are to be
performed,
high
speed
steel drills although more expensive,
will
prove
to be the
better tool
as
higher operating speeds
are
possible plus longer
cutting
edge
life.
The
solid center wood
bit has a
single
flute
turn-
ing
around
a
solid center
but
carries
two
spurs.
The fluted bit is an
excellent
all
purpose wood
bit.
It has two flutes
each
terminating
in a
cutting
edge
and
spur.
The
best
bit for
high
quality
machine
drilling
in
wood
is the
spur machine bit.
It is the
stiffest
drill,
tracks nicely
and
produces
an
exceptionally smooth
hole.
For
larger holes,
a
hole
saw is
available
for
either
metal
or
wood. This
bit has a
center drill
for
pilot
and
teeth around
the
outer
rim
similar
to a saw
blade.
Also,
for
large holes
in
wood
an
expansion
bit
may
be
used. When
the
expansion
bit or any
hand
wood
bit is
used
in the
drill
press,
the
screw point
must
have
the
threads removed
from
it so
that
it
will
not
enter
the
wood
too
rapidly.
These
threads
may be filed
off. (See Fig.
3.)
Countersinking
in
wood
may
best
be
accom-
plished
by
using
the
double
lip
style.
It
will
give
the
cleanest
cut and
will
not gum up
under con-
tinuous
operation.
Length
of
Cutting
lips
must
be

FIGURE

DRILL
SHARPENING:
When grinding twist
drills,
in
order
to
maintain
the
efficiency
of the
drill,
extreme
care
should
be
exer-
cised.
The
dead
center
of the
point must
be
main-
tained,
that
is, the
cutting lips must
be the
same
length,
Fig.
4.
Also
their angle
in
relation
to the
center
line
of the
drill
must
be
equal.
The
angle
should
be
approximately
60
degrees,
120
degrees
included,
for
metal
and 35
degrees,
70
degrees
in-
cluded,
for
wood.
The
cutting
lip
should
be
relieved
gradually
behind
the
cutting
edge
so
that
the
clear-
ance
at the
heel
is
about
1 2
degrees.
OPERATION:
Chuck
removal;
If
at any
time
you
wish
to
remove
the
chuck merely
loosen
the
chuck holding collar
and
continue
to
turn
it.
This
will
force
the
chuck
from
the
spindle taper.
Do not
attempt
to
drive
or
wedge
the
chuck
off as
you
may
damage
the
spindle
or
bearings.
For
extensive
use on
woodworking,
an
auxiliary
table
of
34
inch plywood will
prove
its
worth
in
added work area
and the
protection
from
shifting
of
your work. Fasten
the
plywood table
to the
drill
press
table with
countersunk
screws. This
auxiliary
table
also provides
a
good
surface
for
mounting
a
shaping
fence,
pivot pins
and
other similar units.
It
affords
protection
for the
drill press table when
drills
break through
the
work piece.
When
drilling
through wood,
a
piece
of
scrap
material
under
the
work piece
will
eliminate splinter-
ing
and
mutilation
as the
drill point breaks through.
Another
method
of
preserving
the
surface
is to
reverse
the
work piece when
the
point
of
drill breaks
through
and finish the
hole
from
opposite side.
For
drilling
to a
definite
depth,
such
as a
blind
hole,
the
feed
stop nuts
may be set to the
desired
depth
by
lowering
the
drill
to a
mark
on the
edge
of
the
work
piece
corresponding
to the
depth
of
hole desired.
A
straight piece clamped
to the
table,
as a
guide
or
fence,
has
many uses,
as in
drilling
several holes
the
same distance
from
an
edge
or as a
guide
for
grooving,
fluting
or
milling.
SAFETY:
The
work piece should
be
held securely
on the
table, either
by
clamps, pins,
or a
vise,
to
prevent
its
turning with
the
drill.
A
drill
vise
is an
inex-
pensive
means
of
holding many varieties
of
work
and is
readily
adaptable
for use
with cylindrical
work.
The
drill
vise
or a
V-block
should always
be
used
for
cylindrical work.
In
any
case secure your
work
piece
as it may
break drills
and fly off the
table.
