Through Dovetails
(Optional
Accessory)
When through dovetailing
label the pieces as front,
back, and sides. Mark faces
as inside and out.
Label the dovetail pieces
as shown. A parts will be
clamped under front clamp
bar and routed first with
dovetail cutter. B pieces are
clamped under front bar and
routed with a straight cutter.
When routing pins - outside
faces (face side) must be
away from jig body (B1,B2,
B3, B4).
When routing tails - outside
faces (face side) must be
towards the jig body (A1, A2,
A3, A4).
Before joining the actual
workpiece make a trial cut in
waste scrap timber.
Ensure all pieces are cut
to size and checked for
squareness.
Through Dovetail
Waste Piece
For comb and through
dovetail joints, the waste
piece of workpiece must be
5mm thicker than the work
piece. It should be long
enough to be held securely
by the clamp bars.
The width should be at least
5mm wider than work piece.
The waste piece reduces
likelihood of breakout.

Workpiece
Waste piece
The waste piece for
through dovetail
joints must be 5mm
thicker than the
workpiece to prevent
the cutter touching
the jig body.
