Adjusting the automatic centre locator for edge
dowelling (fig. D1 - D29)
• If the workpieces are wider than 280 mm,
remove the centre locking knobs.
• Slide the displacement stops (11) out of the way
to each end of the dovetailing attachment.
• Place two scrap pieces of wood (12) of the same
thickness (>10 mm) under the ends of the top
vice (13) to support the template. Position the
front edge of the wood 30 mm behind the front
edge of the dovetailing attachment (fig. D3) to
allow the centering bar to move freely.
• Loosen the four screws (16).
• Push the cylindrical part (17) of the plastic cams
(18) through the end holes in the template from
below. One of the small holes (19) should point to
the front.
• Insert a tommy bar (20) into the hole (19) in each
of the cams.
• Mount the two spring-loaded anchor assemblies
(21) by sliding the rod into the centering bar (14)
as shown (fig. D8).
• Hold the rod (24) and push it towards the centre
of the attachment to move the head (23) out.
Push the rod (24) backwards to line up the head
(23) with the rear centering bar (15) and rotate
the rod to engage the head.
• Place the workpiece (26) vertically in the
attachment and tighten the front vice (27).
• Place the top of the workpiece (28) approx. 10 mm
above the top surface of the scrap wood (12).
Do not fully tighten the front vice to allow the
workpiece to be moved.
• Slacken the Allen screws (4) in the adjustment
bushes (3) using a 2 mm Allen key.
• Slacken the locknut (5).
• Adjust the bushes (3) and star knobs (1) to set a
distance of approx. 25 mm between the bushes
(3) and the lugs (10).
• Place the template on the attachment.
The threaded bolts (2) should move freely
through the lugs (10) (fig. D14).
• Use the tommy bars (20) to rotate the cams (17)
and open the centering bars (14) and (15).
The template is positioned on the workpiece (26).
• Release the tommy bars (20) to close the
centering bars.

• Push the template down until its feet are resting
on the scrap wood and its front is resting on the
workpiece (26) (fig. D16 & D17).
• Firmly tighten the front vice (27).
• Open the cams (17) and allow them to return
slowly to their rest position. This will position the
dowelling holes in the centre of the workpiece
(fig. D18).
• Firmly tighten the four screws (16). The spring-
loaded anchor assemblies (21) may now be
removed.
• Hold the template down and rotate the
adjustment bushes (3) against the lugs.
Tighten the Allen screws (4) and the locknuts (5).
Tighten the star knobs (1).
• Unclamp the workpiece and reposition it laterally
to set the dowelling holes to the required position
(fig. D25).
• Slide one of the displacement stops (11) against
the side of the workpiece (fig. D26).
• Remove the template, the tommy bars (20) and
the cams (18).
• Unclamp the scrap wood (12) and move it to the
front against the workpiece. Unclamp the
workpiece and align the top edge (28) with the
top surface of the scrap wood (12) (fig. D27).
Check with a set square.
• Firmly clamp the workpiece and move the scrap
wood back to its former position (fig. D28).
• Replace the template and firmly clamp it in
position with the star knobs.
Preparing the router (fig. E1 & E2)
• Fit the guide bush (31) to the router base using
the screws (32) as shown.
• Mount the cutter (33) in the collet.
Adjusting the depth of cut (fig. F1 - F3)
The total depth of the mating bores in the two parts
to be dowelled together should exceed the length of
the dowel (34) by 3 mm.
• The depth of the bore in the horizontal workpiece
(35) should be 3 mm less than the thickness of the
wood.
• The depth of the bore in the vertical workpiece
(26) should be 3 mm more than the difference
between the dowel length and the horizontal
bore depth.
