Fitting Anti-Tilt Shoe
Fit the anti-tilt shoe to the base of the router. For
TBC routers the fixing screw will locate into the
one of the TBC holes. If non-TBC, the anti-tilt
device can be re-drilled and a suitable size
screw used, or it can be secured with double
sided sticky tape to the router base.
Guiding The Router
The router can be guided around the frame
using a guide bush, a circular sub-base or shank
mounted bearing guided router cutter. The best
method is to use a guide bush fitted to the
bottom of the router. The guide bush should
have a spigot projection of minimum 8mm.
When using the guide bush the router sits on top
of the Varijig frame. Choose a cutter with a
diameter which will pass through the centre of
the guide bush leaving enough clearance. The
cutter can be straight or shaped. The guide
bush follows the inside edge of the frame and
this guides the router around the Varijig frame so
that the shape can be replicated.
As the guide bush is bigger than the cutter there
will be an offset. This offset will need to be
calculated when setting frame size.
Shank mounted bearing guided cutters can also
be used, please note however that extra care
must be taken as the cutting edge may scratch
the frame edge. The router sits on top of the
frame. If the router has a base smaller than
170mm diameter, the Unibase circular sub-base
can be fitted to the router, and this can follow
the inside edge of the router.
Ensure the cutter diameter will pass
through the guide bush leaving at least
a 3mm clearance.
Ensure all fixing screws are tight.
Ensure working position is comfortable
when routing. Keep proper footing and
balance at all times.
