1. Loosen motor link lock screw.
2. Slide motor mounting block to
desired ratio, align marks and tighten
3. Loosen pivot link lock screw.
4. Slide pivot link to desired ratio,
align marks and tighten screw.”
Proceed with use of pantograph as out-
lined in Signgraver (SM100B or SM300)
operating instructions.
*Please Note: These marks MUST be
properly aligned to ensure the best
SPECIAL NOTE: With smaller fonts
and greater reductions (eg. ML212,
4:1) use stylus mounted depth con-
trol (K002B). (See page 11, item 17
in SM300/500 Operating Instruc-
: aE
1. Select the Master Type required.
For demonstration purposes, we show
the word QUALITY. The overall height
of the finished engraved letters will be
one-half the Master Type height plus the
cutter width. Using 1” Master Type, our
engraved letters will be one-half inch
plus the 1/16" cutter width, or approxi-
mately 9/16" overall capital height.
Place the Master Type between the top
edge of the Master Type Plate and the
Upper Master Type Holding Bar, center,
using the scale on the Master Type Plate.
oa a
2. Squeeze the Master Type Bar against
the Master Type as you tighten the three
clamping screws, tighten the center screw
3. Tighten the right Letterlock Clamp-
ing Screw first. Push the bottom of the
left Letterlock toward Master Type as
the screw is tightened. Note: Spacers
may be required between Letterlocks
and Master Type to insure free travel of
Tracing Stylus. Do not over-tighten
4. The scale in photo (1) shows the
Master Type for "QUALITY" to be five
inches long, (2-1/2" either side of
center). Your 2 to 1 ratio machine will
reproduce these letters in an engraved
line 2-1/2” long. We have selected a 1”
by 3 Sign Blank for the sign to be
engraved. Measure and mark the center-
line on the protective coating of the
Sign Blank with a soft pencil.
5. Center the Sign Blank using the
Centering Scale, Clamp the Sign Blank
making sure the edge of the Clamp is on
top of the Sign Blank for proper
6. With the Motor Mounted Depth
Control removed, place the Stylus Tip in
the center groove of a В, Е, F, G, H, P
or R' Master Type Letter, or in the
center vertically of a ‘D, |, K, L, M, N
or T." (Measure and mark the center if
necessary.) Loosen the Engraving Posi-
tion Clamping Knob and slide the Sign
Blank Plate until the Cutter point lines
up with your pencil center line on the
Sign Blank. Tighten the Clamping Knob
and replace the Depth Control.
7. Plug in and switch the motor on,
grasp the Finger Grip and place the
Stylus Tracing Point in the first Master
Type Letter to be engraved. Press down
on the Finger Grip until the Depth Con-
trol contacts the Sign Blank. Each
Master Type Letter should be traced
twice, once with the Stylus pressed
slightly to the bottom, or right edge of
the Master Type groove, and again with
the Stylus pressed to upper or left edge
of the Master. This assures good quality
engraved letters. When all the Masters
have been traced in this manner, switch
off the motor, raise the pantograph up
and out of the way and check each
letter to see that it is completely en-
graved. A small brush will aid in re-
moving chips for inspection. If any areas
are not deep enough or have been
missed, engrave them again before any-
thing is moved.
9. The machine is equipped with two
Type Holding Bars and four Horizontal
Letterlocks (two containing nylon
screws and two containing socket
screws). This allows two rows of Master
Type to be clamped at one time for
engraving. The Horizontal Letterlocks
with nylon screws are on the Upper
Type Holder Bar for engraving with a
single row of Type because they are
more convenient to use. When using two
rows of type at one time, the Letter-
locks should be interchanged so those
with the socket screws will be on the
Upper Type Holder Bar. This prevents
interference of the Pantograph with the
Nylon Letterlock Clamping Screws while
engraving the second row of type.
8. Remove the protective skin of the
Sign Blank at this time to aid in your
final inspection. Once the Sign Blank
has been removed it is extremely diffi-
cult to re-align it to engrave a missed
section, Before removing it, check and
inspect thoroughly.
10. The upper row of type is centered
and clamped first.

Caution: Two rows of Master Type
can be clamped at one time only if their
overall combined blank heights do not
exceed 3-3/4 inches.
When using large masters (i.e.: ML17)
it may be necessary to remove the lower
Type Holder Bar from the Master Type
12. Scott Signgravers are shipped from
the factory with 1/16” Cutter installed,
ready to engrave. To change cutter, first
remove the Motor Mounted Depth Con-
trol. Place a hex wrench through the
hole in the top of the motor shaft to
prevent rotation and loosen the Collet
Nut. Remove cutter and replace with
one of your choice.
With the motor stopped, loosen
the Clamping Screw and the Depth
Control slightly, adjust the motor so the
cutter can just be felt thru the Depth
Control with the thumbnail. Tighten the
Motor Clamping Screw and Depth
Control. Place the Stylus Tip in one of
the Master Type Letters and turn the
motor on. Holding the Finger Grip, press
down until the Depth Control rides on
the Sign Blank and trace one letter.
Turn motor off and lift back out of the
way. Check the depth of cut. If it is too
shallow (core not completely exposed)
loosen the Motor Clamping Screw and
advance the motor about 1/8 turn.
Reclamp the motor and tighten the
Depth Control.
13. Loosen the Collet Nut just enough
to position the Cutter. Use the Scott
Cutter Gauge to adjust the Cutter so
that it projects 3/8" from the bottom of
the Collet Nut to the tip of the Cutter.
Tighten the Collet Nut and remove hex
Motor should be elevated from the
motor link (note arrow) the width of the
Cutter Gauge for proper adjustment.
16. Note: The depth of the cut is
decreased by rotating the motor
counter-clockwise and increased by
rotating the motor clockwise. When
decreasing the cutter depth, the depth
control must first be loosened. Engrave
only deep enough to completely expose
the core. Remember, if you cut too
shallow at first you can always engrave
deeper, but if your first cut is too deep,
you can't put the material back.
14. Replace the Motor Mounted Depth
Control on the Threaded Motor Housing
until it locks against the Motor Link of
the Pantograph. The Depth Control rides
on the surface of the Sign Blank. The
amount of cutter that is exposed is the
depth of cut. Engrave just deep enough
to cut away the surface color. A cut
that is too deep can ruin the sign ma-
terial. It is best to start with a shallow
cut, then increase to required depth.
17. When engraving close to the edge
of a name tag, the Motor Mounted
Depth Control may strike against the
Sign Blank Clamp. In this case, the
Stylus Mounted Depth Control should
be used. Remove the Motor Mounted
Depth Control and place the Stylus
Mounted Depth Control on the Tracing
Stylus. Lock it in place so it stops the
Finger Grip when the cutter just con-
tacts the surface of the Sign Blank. The
cutting depth is adjusted by loosening
the Motor Clamping Screw and rotating
the motor as described in Step 16. The
Stylus Mounted Depth Control should
also be used if the Motor Mounted
Depth Control is leaving marks on the
engraved material. Always remove one
Denth Cantral before installina the
18. A message which is too long to be
engraved with the Pantograph centered,
can be engraved by using the Set-Over
For demonstration purposes we will
use the message ... "SET-OVER PRO-
one inch Masters for 9/16” overall height
finished letters. The overall length of our
Master Type set-up is about 25-3/4”. The
engraved message will be one-half this
length, about 13”. Our Sign Blank size is
1 x 15”. Select the Master Type,
including spacers and arrange them on
the work bench to spell the message.
Measure the overall length (not to ex-
ceed 34''). Mark the center on the top
edge of a Master. Place the marked
Master on the center of the copy plate.
Install as many Masters as possible either
move the Motor Mounted Depth control,
loosen the Pantograph Position Clamping
Screw, insert the Stylus Tip in the master
of the last letter engraved on the right
and slide the pantograph to the right until
the cutter drops exactly into the letter
previously engraved from that master.
Clamp the Pantograph in that position.
Replace the Motor Mounted Depth Con-
trol. Do Not Re-Engrave the letter used
to position the Pantograph. Engrave
the remaining letters at the right end of
the sign.
Return the Pantograph assembly to
the center position and clamp it there for
the next engraving job.

the mark on the master with the center
of the Master Type Centering Scale and
clamp the Master Type in that position
using the Type Holding Bar and Hori-
zontal Letterlocks.
19. Engrave only the letters that can be
completely engraved. Check and see if the
Pantograph will reach the Masters at each
end. Don't engrave them if you cannot
reach them with the Pantograph arm.
After engraving, loosen the Horizontal
Letterlocks and the Type Holding Bar.
Remove all the Masters except the last
one engraved on each end. Slide these
Masters to the center and position the
remaining Masters required to complete
the message.

21. To engrave Name Tags and Pocket
Badges, the Sign Blank Plate is re-
positioned as follows:
Loosen the Engraving Position Clamp-
ing Knob, pull the Sign Blank Plate all the
way out. Turn it over and re-insert.
With the Sign Blank Plate in this, the
Number 2 position, there are special
clamping devices that hold Pocket
Badges and Name Tags. The
special slots support Name Tags so that
they can be engraved with Pinbacks or
Clutches attached.
Always insert a piece of 1/8" material
(or two pieces of 1/16”) into the Pocket
Badge before engraving. This makes the
surface level for distortion-free engraving.
To complete the left side, position and
clamp the Masters at the left side of the
Master Type Plate.
20. Remove the Motor Mounted Depth
Control, loosen the Pantograph Position
Clamping Screw, insert the Stylus Tip in
the master of the last letter engraved on
the left and slide the pantograph to the
left until the cutter drops exactly into
the letter previously engraved from that
master, Clamp the Pantograph in that
position. Replace the Motor Mounted
Depth Control. Do Not Re-Engrave
the letter used to position the
Pantograph. Engrave the remaining
letters at the left end of the sign.
Position and clamp the Masters to
complete the right end of the sign at the
right end of the Master Type Plate. Re-
Nametags can be cut out in any desired
shape as follows:
Clamp a template of the desired shape
(twice as big as the finished nametag) on
the master type plate.
Clamp a piece of scrap stock (larger
than the finished nametag) on the Sign
Blank Plate. (To prevent damage to
Fasten a sign blank (from which the
nametag is to be cut) to the piece of scrap
stock using double sided tape.
Position the Sign Blank Plate to align
the cutout on the sign blank.
Adjust the depth of cut so the cutter
will cut completely thru the sign blank
and slightly into the scrap stock.
Engrave completely around the tem-
plate to cut the shaped nametag from the
sign blank with a CA2 Cutter,
Set up and clamp the Master Type to
spell the message on the nametag.
Adjust the depth of cut to cut only
thru the surface color.
Move the Sign Blank Plate and the
Pantograph as necessary to position the
engraved message in the desired location
on the nametag.
Engrave the message.
Large quantities of the same shaped
cutout nametags can be produced faster
by cutting out all the nametags first and
then engraving the message.

Materials that can be engraved on the
Scott Signgraving Machine are: plastics
(laminated and solid color), plexiglass,
metals and wood.
Laminated Plastics
The laminated plastics materials are
made up of a thin surface layer and a
backing material called the “core” that
is a contrasting color. They are used in
most engraved sign applications. En-
graving removes the surface layer so the
letters or pattern shows the core color.
Laminated plastic materials are
made in 2 and 3 ply and in two kinds
of materials, flexible and rigid. Two-
ply has the thin surface layer on
one side of the core and is used where
only one side of the sign is to be seen,
(i.e. fastened on a wall or held in an
extrusion). Three-ply has the colored
surface layer on both sides of the core.
It has no strength advantage over two-
ply and is used only when both sides of
the sign are engraved and visible, (i.e.,
projecting corridor signs).
Scott-Ply laminated plastic is available
in both 1/16th and 1/8th inch thick-
nesses. 1/16th is used in most 2-ply
applications where it is attached to a
surface, held in an extrusion or used as
small signs. 1/8th is used in most 3-ply
applications as in projecting corridor
Scott-Ply (flexible) is usually used for
most engraved signs and may be sawed,
sheared, beveled, drilled, and engraved
with standard wood-working tools. It
2" Letter
mounted on curved surfaces because it is
flexible. It has film on the surface to
protect the surface color while it is
being cut and engraved. The protective
film is removed AFTER engraving.
Rigid material is similar to Formica
counter top material. It is used where
signs are subjected to high temperatures,
chemical solvents or exposed to rough
usage. Carbide tools must be used to
saw, bevel or engrave it.
Solid Color Plastics
Solid color plastics are the same color
all the way thru. They are engraved and
then the engraved letters or pattern can
be filled with a paint stick or liquid
paint of a contrasting color.
Clear plexiglas may be engraved on
either the front or back surface. En-
graving on the back surface protects the
letters and gives an attractive three-
dimensional affect, but requires the use
of special Reverse Masters (mirror
image) to make the lettering legible
from the front. The letters may be filled
with a paint stick or enamel paints as
desired. Interesting affects can be
achieved by placing lights near the edge
of the pieces. A small cutter with a deep
cut (at least half way thru the material)
is recommended, if special lighting is to
be used.
Metals and Wood

Light cuts are made and depth increased
several times until the required depth is
reached. Free-machining alloys of brass
or aluminum are required for engraving.
A diamond drag can be used on the
metals for fine line engraving such as
trophy plates. (Do not switch motor on
when diamond drag engraving.)
Wood may be engraved with High
Speed Steel or Carbide cutters. The en-
graved area may be filled to provide a
contrasting color.
Master Type Fonts
Scott Master Type may be purchased
individually or in a complete assortment.
This assortment of pre-packaged Master
Type is called a Font. Scott Sign-
graverR Fonts are made of DelrinR, or
hard Phenolic for exceptional durability.
Phenolic Master Type requires light oil
lubrication for best results.
Certain Master Types could be incor-
rectly used (6 or 9, or an $), To prevent
this the Master Type have either a dot
on the bottom or a small notch at the
top. Care should be taken when using
the letter “0” and number (zero). They
are nearly the same but the “zero” is
narrower than the letter “0”.
In each font there are Master Type
for the high © in (MC) and low C and A,
as in “Mac”. Some fonts have a low R
and S for (MR. and MRS.). Arrows and
many Organization Symbol Templates
are also available. (Templates or logos

Making signs is not a difficult operation.
The following guidelines provide all the
information you require for making
attractive and functional signs.
Effectiveness of signs is determined
by their ability to communicate the
message. The ability to attract attention
is a result of the contrast between the
mounting surface and the sign color,
The higher the contrast, the more at-
tention the sign will attract.
In addition to color, you must also
consider letter style, letter size and view-
ing distance, length of message, sign size
and placement of sign.
Consider them, one at a time.
Contrast between the surface color and
the engraved letters increases legibility.
A black surface with white letters or a
white surface with black letters repre-
sent maximums.
Color influences. Colors relay emo-
tional messages. Warm colors (reds,
oranges) excite and stimulate. Cool
colors (blues, greens) are quiet and sub-
Color coding of signs by departments,
personnel functions, products, etc., is
very effective. Standardization of
specific colors for constant meanings
increases effectiveness when it is carried
out in a systematic manner.
Another example of this would be
the use of the same color combination
in a specific area or condition. All door
signs, for example, one color, all direc-
tional signs another color.
It's easy to see that signs can be
bright and conspicuous or quiet and
subdued. It's up to you and your needs.
Letter Style
Scott Standard and Helvetican type
styles have maximum legibility. Script
and other artistic styles lend interest-
ing variations but tend to reduce
legibility somewhat.
Letter Size and Viewing Distance
A general rule with good lighting condi-
tions and legible type style is: use a
minimum of one inch of letter height
for each 35 feet of viewing distance.
Standards may be set up for letter
height in specific applications. Door
signs should have 1" finished letter
height, desk signs should have 9/16”
finished letter height, name tags are
usually finished in a 3/16” or 5/16”
letter. Distances indicated in the chart
can be followed for most installations.

Length of Message
The name or message should be spaced
properly on the Sign Blank not pinched
or squeezed. Multi-line messages require
additional consideration. Don't be afraid
to use extra space between lines, it can
add emphasis and increase legibility.
Scott offers a simple, but unique
Slide Rule Guide, designed to assist you
in planning length of message and Sign
Blank size.
Sign Size and Placement
Using standardized sign sizes will assist
message transfer, not just by word
alone, but, just as importantly, by size.
Signs are best read at eye level, on a
plain background. A confusing back-
ground will diminish visibility.
