tool, as close as 1/2" when 3/4" bit is used
(Removal of the black offset spindle cover
further reduces distance from 3/4" bit and
vertical surface to 3/8".) The 1-1/16" base
opening makes it possible to use bits that
have cutters as wide 13/16".
The offset base can also be used to scribe
the back of a new counter backsplash so
that it will mate precisely with the wall
against which it will rest.
The nature of a belt drive mechanism, like
the one in the offset base, is different than
a typical palm router base. To help mini-
mize heat build-up, the offset base has been
designed with large bearings, specially-de-
signed heat sinks, carefully-directed airflow
and plastic heat shields. Depending on the
application, the offset base can be used for
up to about 10 minutes continuously before
it will need to be left idle so that it can cool
off.
The principles of using the offset base are
basically the same as for the fixed base rout-
er setup (palm router in fixed base assem-
bly, see "Using the Palm Router with Fixed
Base" on page 31, with the following dif-
ferences:
• Grip the Offset Base 29 with one hand
using Palm Router Grip Area 2 and the
other hand gripping the back of the
base housing or the top of the offset
spindle.
• For routing backsplashes and other
elevated workpieces, some install-
ers mount the offset base to a wood
block that matches the height of the
laminated backsplash. This helps to
maintain a consistent angle between the
bit's cutter and the workpiece; this also
provides addition stability.
Note: Cutting with an offset base does not
require changes in depth.

Operation
Offset Base Roller/Bushing Guide
(optional accessory)
(Fig. 41)
The offset base roller/bushing guide is re-
quired when edge-forming or trimming with
unpiloted non-bearing bits.
1. Install the Offset Base Roller/Bushing
Guide 54 to the Offset Base 29 and ad-
just it as needed, see section "Attaching
the Offset Base Roller/Bushing Guide"
on page 17 and "Adjusting the Offset
Base Roller/Bushing Guide" on page
18.
2. The router should be fed normally, keep-
ing the guide in contact with the edge of
the workpiece at all times. See "Feeding
the Palm Router" on page 30.
3. To maintain a consistent width of cut,
a consistent angle must be maintained
between the router and the workpiece.
