Producing an Elliptical Plaque in MDF
This example does not include the use of
bearing guided cutters
moulded plaque
waste piece
Draw plaque dimensions onto workpiece and
clamp to a false baseboard to prevent routing
into the workbench. Secure centre area of
plaque to baseboard (see clamping section) to
prevent plaque from moving when breakthrough
is achieved.
Produce the mould required with a panel type
cutter.
Repeated operations can be made with more
cutters to achieve a custom design of mould.
Adjustment in the size of the ellipse can be
made by using the measurement scale on the
main plate to adjust both pivot point positions.

Change the cutter to a straight and take
repeated passes until breakthrough is achieved.
Align the cross frame with the line up notches. It
is advisable to secure the cross frame to the
workpiece using double-sided tape, this is easily
removable and will not damage the workpiece.
After use remove router from jig and store jig
carefully.
