saw out the waste from areas such as
the scoring arches.

For safety and accuracy, it is advisable to cut the
inclined ramp grooves of the Marble Run on a
router table. If using the router handheld, fit a
second side-fence to keep the groove centred.

Solitaire Game
An excellent method of holding the
wood when routing the solitaire
board, is to mount it on a square
block of scrap timber using doublesided tape. It can then be securely
held in a vice.
Routing the Hollows
Starting at the centre of the square
piece of timber, use a bradawl to
mark each centre point at 20mm
centres. As the router is to be
positioned manually, it is best to start
each hollow using a countersink bit,
preferably mounted in a piller drill.
This will help to locate the cove
cutter accurately over each point.
Each hollow is then plunge cut using
a cove cutter mounted in the router
(suggest cutter ref 13/2, C056 or
Nova tool B and blade B53). Set the
depth of cut to leave a hollow 5mm
deep. Both the outer edge of the
board and the marble retaining
groove are cut using a suitable beam
trammel fitted to the router. With
the Trend T5 router a separate
trammel point is provided for fitting
to one of the side-fence rods.

Ensure that the centre point is
located securely in the centre
hollow.
The marble retaining groove is cut
to an internal diameter of 150mm
and a depth of 5mm, using the
same cove cutter as used for the
hollows.

Trimming the Board Edge
The outer edge of the board can
be trimmed using a two flute
straight cutter guided by the beam
trammel. The cove around the
bottom edge is cut using a bearing
guided cove cutter (Suggest cutter
ref 46/260, C060 or Nova tool A
and blade A11).
