Trimming Jig
Common sense as much as
regulations is the keynote to safe
routing, so when it comes to using
the router table, the best thing is to
comply with both and use a jig rather
than your fingers when presenting
the work to the cutter.
The jig for trimming the seat slats for
the chair illustrated, consisted of a
simple template with the edge cut to
the slat profile.
Extra length was allowed at both
ends of the template to provide leadin and lead-out sections and a batten
was screwed to the face to stop the
workpiece being forced backwards.
End socket clamps where
used to attach the
workpiece, fitted into holes
drilled through the edge of the
board. Cut-outs were formed
(using a forstner bit) to allow
the clamps to be inserted
from the back, keeping
them clear of the cutter.
The holes on the template
face were plugged and
trimmed flush to prevent the
guide bearing of the trimming
cutter from snagging.

When trimming curved edges always ensure that
a lead-in or copy pin is fitted to the table to
prevent the workpiece snatching and being
dragged behind the cutter. Cut away most of the
waste from the edge prior to trimming flush,
leaving no more than 3mm.
When trimming on a router table ensure that
you cut in the correct feed direction, that is from
right to left, against the rotation of the cutter.
3 Clamp Guide Slide Block
Designed for use with Trend Clamp Guides, this captive
slide prevents the router from running away from the
guide edge.
Cut and finish the hardwood block square before using
the router’s side-fence and a large diameter cutter to
rout a 55mm wide by 16.5mm deep groove across one
face. A recess is cut into the top face to provide a
clearance for the side handle of the router.
Two 8mm holes are drilled in the side of the block to
accept the router’s side-fence rods. Two M6 hex bolts,
screwed into threaded inserts are fitted to retain the
rods and a guide knob is fitted to the top. IP

The Clamp guide is fitted on the work, parallel to the line of
the cut, allowing for the width of the block and router. Final
positioning of the cutter on the line can be carried out by
sliding the router along the rods. In use the router is guided
by one side handle of the router and the slide block knob.
