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

Model 1609A

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.

Using Self-Piloted Bits

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.

Templet Guides

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.
