RATE OF FEED
FIG. 14
When routing or doing related work in wood
and plastics, the best finishes will result if the
depth of cut and feed rate are regulated to
keep the motor operating at high speed. Feed
the router at a moderate rate. Soft materials
WORKPIECE
require a faster feed rate than hard materials.
The router may stall if improperly used or
overloaded. Reduce the feed rate to prevent
possible damage to the tool. Always be sure
the collet chuck is tightened securely before DIRECTION OF ROUTER FEED
use. Always use router bits with the shortest
cutting length necessary to produce the
desired cut. This will minimize router bit run-out
and chatter.
FIG. 15
It may be necessary to make the cut in more
than one pass with progressively deeper
settings to avoid overloading the motor. If the
bit cuts freely and the motor does not slow
down, the cutting depth is generally correct.
GUIDING THE ROUTER
The router can be guided through the work in
any of several ways. The method you use
depends, of course, on the demands of the
particular job and on convenience.
For routing operations such as grooving or
dadoing, it is often necessary to guide the tool
in a line parallel to a straight edge. One
method of obtaining a straight cut is to securely
clamp a board or other straightedge to the
work surface, and guide the edge of the router
sub-base along this path (Fig. 15).
PR002 STRAIGHT ROUTER GUIDE
(Included with PR20EVSK & PR20EVSNK,
also available as optional accessory)
FIG. 16
The router guide is an optional accessory that
will guide the router parallel to a straight edge
(Fig. 16).
The router guide is supplied in two parts held
together with a bolt, wing nut and washer. It
also includes a wing screw and washer to
fasten the guide to the router.
The guide features a scale for accurately
positioning the edge guide relative to the bit.
With the guide installed and adjusted, the
router should be fed normally, keeping the
guide in contact with the edge of the workpiece
at all times.
The router guide can also be positioned
directly under the router base for operations
where a cut is needed close to or at the edge
of the work, such as when rounding off deck
planks.
