The second very useful positioning ac-
cessory is a saddle fence that attaches
to the bottom of the moving portion of the
fence. Here the Domino body is removed
from the fence to make it easier to see.
The saddle fence slides onto the fence
and locks in place via the two black
knobs and metal fingers (green arrow).
The photo above right shows the bottom
of the saddle fence. It features two mov-
able fence elements that run parallel with
the in-out motion of the cutter (yellow ar-
row). They capture and hold the edges of
the work piece making it easy to cut mor-
tises in the end grain. The green knobs
secure the fences in the desired position,
and on top (detail below), is a scale that
indicates how far away those fence sides
are from the vertical center of the mortise
slot.
Want to cut a 10mm mortise in the center
of the end of a 20mm x 50mm work
piece? Set the fence to 10mm high and
set the two sides of the saddle fence to
25mm as shown above. The resulting
mortise will be exactly centered in the
