Friction-Fit Method

Use this method when installing Rasters™ in 
plastic or acrylic substrates. The Rasters™ are 
held in place by the friction fit between the 
Raster™ (which is 0.0625” in diameter) and 
the hole (which is 0.060”). This method is not 
recommended for use with ABS plastics. For 
ABS, use the adhesive-assist method.

1. Set up the red-labeled Raster™ Braille 
cutter in your machine.

2. Use your engraving software to create the 
Braille message and run the machine. Make 
sure your software uses a single-point drilling 
function to drill the holes. Use the same speed 
settings you use when engraving plastic. Drill 
to a depth of  0.042".

3. Move the sign to a clean area and make sure 
the holes are free of  debris. If  you are using 
clear Rasters

, any leftover plastic chips in 

the hole will be visible through and magnified 
by the Raster

, so keep your work area clean.

4. Use the Raster™ Pen to insert Rasters™ 
into the holes. The Rasters™ should "pop" 
into place without much force. If  too much 
force is needed, or if  the Rasters™ won't stay 
in the holes, drill the holes a little deeper and 
try again.

5. Check the height of  the installed Rasters™ 
with calipers. Measure the thickness of  the 
material next to the Braille, then measure the 
thickness including the Braille, then subtract. 
The height should be 0.025" to 0.031" (0.6-0.8 
mm). If  the Rasters™ sit too low, try drilling 
the holes a little shallower.

Working with
Acrylic

Here are a couple 
tips to make 
working with 
acrylic a little 
easier:

1. Slow down the 
RPM of your 
spindle. Acrylic 
has a low melting 
point and the 
cutter can get hot 
enough to melt 
the edges of the 
holes if the RPM is 
too high.

2. Don't use 
alcohol or 
petroleum-based 
cleaners on an 
acrylic sign. These 
products will  
attack the acrylic 
and cause tiny 
cracks to appear 
around the Braille 
holes. Use soap 
and water or a 
mild detergent.
