OPERATION
Fig. 14
WARNING
Always securely clamp your workpiece
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. If using a router table, large cutter bits should
be used for edging only.
FREEHAND ROUTING WITH THE FIXED BASE (FIG. 15)
WARNING
Do not use large cutter bits for freehand
routing. Using large cutter bits when freehand routing
could cause loss of control or create other hazardous
conditions that could result in personal injury. If using
a router table, large bits should be used for edging
only.
When used freehand, the router becomes a flexible and
versatile tool. This flexibility makes it possible to easily
rout signs, relief sculptures, etc.
When freehand routing:
1. Draw or lay out the pattern on the workpiece.
2. Choose the appropriate bit.
3. Follow the instructions for INTERNAL ROUTING, and rout
the pattern in two or more passes. Do not exceed 1/8”
depth of cut in a single pass. This will help provide better
control, as well as serve as a guide on the next passes.
NOTICE: A core-box bit or V-groove bit is often used for
routing letters and engraving objects. Straight bits and ball
mills are often used to make relief carvings. Veining bits are
used to carve small, intricate details.
NOTICE: Making a single deep cut is never advisable.
Smaller-diameter bits are easily broken by too much side thrust
and torque. Larger bits will cause a rough cut and be difficult to
guide and control. For these reasons, do not exceed 1/8” depth
of cut in a single pass.
WARNING
Always securely clamp your 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.
EDGING WITH A PILOT BIT (FIG. 16-17)
Arbor-type bits with pilots are excellent for edge shaping of any
workpiece edge that is either straight or curved at a curvature
as great as or greater than the radius of the bit to be used.
The pilot prevents the bit from making an excessively deep cut;
and holding the pilot firmly in contact with the workpiece edge
throughout prevents the cut from becoming too shallow.
