The guide bearing
ensures the bit follows
the workpiece.
Where the material thickness leaves
insufficient room for the bearing to make
contact, a second piece of material can be
temporarily fixed beneath it for the ball
bearing to follow.
Keep downward pressure with
the inside hand to prevent the
router from tipping.
Bearing Guided Bits
Edge profiling and shaping bits are available with
a bearing fitted to the end. This enables shaped
or straight workpieces to be routed without the
need for a guiding device such as a side-fence
or batten.
The edge must be free from imperfections as
these will be reflected in the finish of the mould.
Often alternative diameters of bearings are
offered which will change the shape of the
resulting mould.
With certain shapes such as the chamfer bit
below, increasing the depth of cut will produce a
larger chamfered edge.
■
Fit the bearing guided bit into the router collet.
■
Place router onto the workpiece.
■
Set height of bit using the depth stop (1).
■
Switch on the machine.
■
After releasing the plunge locking lever (2),
lower the machine slowly as far as the depth
stop.
■
With bearing of bit running along board edge,
mould the edge of the workpiece by moving
the router in the direction shown.
■
A continuous motion should be used to
prevent burning of the workpiece. When
possible, take a number of passes at
increased bit depths. A light final pass will
produce a good finish.
■
When complete, retract the carriage by
releasing the locking grip knob.
■
Switch off the router.
