To create a joint, contact cement should be
applied to the core material and the plastic
laminate, and one piece of laminate should be
fastened to the core with the other overlapping
it by about 3/4". The fixed piece must have a
clean, straight edge as it will serve as a guide
for the underscribe base to follow. The over-
lapping sheet of laminate will then pass over
the aluminum plate and be cut to the proper
length by the router bit. (See Figure 14). This

accurate system makes it a perfect tool for
joining laminate on stile and rail constructions,
circular or curved edges, and many other sur-
faces. Because the cutter will generate chips, it
is necessary to keep the laminate pressed down
tightly near the seam to keep these chips from
getting into the joint—this is especially impor-
tant on larger pieces of material. It is also
necessary to keep steady pressure on the tool so
that the guiding edge of the base remains in
contact with the fixed piece of laminate through-
out the operation. (See Figure 15). This is
especially important at the beginning and end
of a cut.

An eccentric adjuster is fitted to the aluminum
plate and if necessary, can be adjusted with the
pin wrench provided, after loosening the two
screws which mount the aluminum plate. To
make the joint tighter, turn the eccentric clock-
wise. For a looser joint, turn the eccentric
counterclockwise, as viewed from under the
base (see Figure 16). It is advisable to make
some test cuts on scrap material to determine if
adjustment is required before beginning work,
and to be certain that the screws are re-tight-
ened after adjusting the eccentric. Once this is
done, no further adjustment should be required.

Note that the base receives a preliminary ad-
justment at the factory, but will generally need
to be "fine tuned" by the user to produce a
perfect seam.
Offset trimmer 1609A is primarily used for
trimming laminate in confined areas such as
backsplashes, corners, or other locations inac-
cessible to the standard trim bases (see Fig 17).
Piloted bits may be used, or the laminate trim
guides may be fitted for use with unpiloted
bits. Note that the offset base is designed for
these specialized laminate trimming applica-
tions, and is not suitable for heavy stock re-
moval or continuous service.
Self-piloted bits have an integral round tip or
ball bearing which rides against the work sur-
face above or below the cutters to control
horizontal cutting depth. When using these
bits, the trim guide is not required, and it is
only necessary to adjust the cutting depth to
allow the pilot to ride on the work surface.
When guiding against a laminated surface, use
wax or other lubricant and do not apply excess
pressure or the piloted end may mar the work.
Bearing pilots must be kept clean and free of
adhesive or other residue. Router bit bearings
are sealed and permanently lubricated, and
should be replaced when they no longer turn
freely to avoid damaging the work surface.
Your Bosch trim router Model 1608 will ac-
cept optional Bosch templet guides for pattern
and other fixture work. To install a guide,
remove the sub-base 7, insert the desired tem-
plet guide into the sub-base recess, and rein-
stall the sub-base. (Templet guide screws are
not used - the sub-base holds the guide in
place). See your Bosch dealer for templet guides
and other accessories.
