DIRECTION OF FEED – INTERNAL
CUTS (FIG. 19-20)
When making an internal cut, such as a
groove, dado, or slot, always try to have the
guide you are using with the router (edge
guide, straight edge, board guide), on the
right-hand side of the router as you make
the cut (FIG. 19).
When the guide is positioned on the
right hand side of the router, the router
travel should be from left to right and
“counterclockwise” around curves (FIG. 19).
This counterclockwise action around the
curve could cause “Climb cutting”. Always
be alert and exercise extreme caution to
maintain control of the router when making
this type of cut around curves.
When the guide is positioned as shown in
FIG. 20, the router travel should be from left
to right and clockwise around curves.
If there is a choice, the set-up in FIG. 20
is easier to use, but there is the possibility
of “Climb Cutting” around curves. In either
case, FIG. 19 or FIG. 20, the sideways thrust
of the router cutting is always against the
guide, as is proper.

WARNING:
Always securely clamp
the workpiece in place, and keep a rm
grip on the router base with both hands at
all times. Failure to do so could result in
loss of control causing possible serious
personal injury.
RATE OF FEED (FIG. 21-22)
The proper rate of feed depends on several
factors: the hardness and moisture content
of the workpiece, the depth of cut, and the
cutting diameter of the bit.
When cutting shallow grooves in soft woods,
such as pine, you may use a faster rate of
feed. When making deep cuts in hardwoods,
such as oak, you should use a slower rate
of feed.
