The line-up pin fits into the collet and is plunged
through the router base. The line-up bush is
fitted into the UNIBASE and secured. This is then
placed over the line-up pin and rotated in order
to line up the fixing holes. The UNIBASE screws
are tightened and then the line-up bush can be
replaced with any choice of Trend guide bushes.
These range from 10mm up to 32mm (GB10 GB32). For larger diameter cutters a 40mm guide
bush (GB40) is available. See opposite page.

CUTTER TEMPLATE/GUIDE BUSH
RELATIONSHIP

The chart on the left shows the offset which results from using a specific
size of guide bush and cutter. This offset shown on the shaded areas
should be calculated prior to producing a template. All the guide bushes
will fit the UNIBASE, GB/5 and GB/PLATE sub-bases - see opposite.

GUIDE BUSHES WHEN HAND
ROUTING

Guide bushes are required when material has to be profiled or
routed to a set pattern or shape.
In operation, a suitable guide bush is first mounted on the router base or sub-base.
When choosing guide bush and cutter, make allowances for a recommended
minimum of 3.5mm between cutter and outside of bush. This ensures there is
enough clearance to allow the waste to clear the guide bush.
The diagram shows the relationships between the cutter, guide bush and template.
The offset (E) gives the position the template must be distanced from the finished
workpiece.
This difference is shown in the chart on the left by the shaded area relative to the
range of bushes and cutters available.

Deduct the cutter
diameter from
outside diameter
of guide bush and
divide by two.
