Direction Of Feed - Internal Cuts; Rate Of Feed - Craftsman 320.27669 Operator's Manual

DiRECTiON OF FEED = iNTERNAL CUTS
(Figs. 21 and 21a)
When making an internal cut, such as a
groove, dado, or slot, always 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.
21)
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 (see Fig.
21). 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.
21a, the router travel should be from left to
right and clockwise around curves.
If there is a choice, the set-up in Fig. 21 is
easier to use, but there is the possibility of
"Climb Cutting" around curves, in either case,

Fig. 21 or Fig. 21a, 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 firm
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 (Figs. 22 and 22a)
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
Fig. 22
in hardwoods such as oak, you should use a
slower rate of feed.
FEEDING TOO QUICKLY (Fig. 22)
Clean and smooth cuts can only be achieved
when the cutter bit is rotating at a relatively
high speed, taking very small bites, producing
tiny, clean-cut chips.
