Method 3.
The procedure for this joint is very similar to the
edge to corner joint.
The first board is clamped to the workbench
in exactly the same way (
The drilling depths are calculated as above.
Procedure
1. Adjust the depth stop to 28mm, drill all holes in
horizontal board.
2. Readjust the depth stop to 10mm, put safely to one side.
3. Mark a centre line on the second board where the boards are to be joined.
4. Lay the first board on top of the second board (
5. Place jig on one end of the second board (
board until the centre line can be viewed in the dead centre of the relevant guide
bush.
6. Check drill is still set to 10mm (step 2). Locate
the jig on protruding dowels using the
corresponding slot to the guidebush being
used for drilling (8mm) see Fig. 12. Drill all
holes in second board ensuring the jig is held
square and firmly against the edge of the
first board.

(edge to corner).
Operation
The procedure for this joint is very similar to the edge to edge joint.
The first board is clamped to the workbench in exactly the same way (
The second board is stood on its edge as in Fig. 7 with the
upper clamps from behind, see Fig. 8.
Fig. 1
).

Fig. 7
Two hole depths are required when drilling dowel holes in edge to corner joints.
The depth stop positions are determined by the board thickness as follows.
Fig. 9
Board thickness (15mm
in this example)
The vertical board (
1. Measure the board thickness (15mm), calculate two
thirds = 10mm, this is the depth of hole to be drilled in
the board surface.
2. Slide the depth stop onto the relevant drill bit and adjust
as before (
the jig.
The horizontal board (
Based on the dowels being 37mm in length, the holes need
to be 27mm + 1mm deep to ensure the dowels do not
bottom, thus preventing the boards meeting properly.
Adjust the depth stop so that the drill protrudes 28mm
through the jig.
Procedure
1. Drill all holes in horizontal board, remembering to
withdraw it regularly to clear any swarf.
2. Readjust the depth stop to 10mm and drill all holes in
vertical board.

Please note, these instructions are guidelines only and not a definitive tutorial for the
construction of all joints possible using the dowel jig, however with a little imagination
and experience, this jig will be found more versatile than you could ever imagine.
The three most common uses are:
1. Edge to edge joints.
2. Edge to Face joints. 3. Edge to corner joints.
Method 1.
NOTE: figures in brackets refer to contents
on page 2.
Lay first board on work bench (Fig. 1),
secure in position with dowel jig (A) and
clamp block (B). Ensure the board hangs
over the edge of work bench sufficiently so
that the board edge is tight against the jig
and clamp block.

The next step is to choose the dowel size.
The size of dowels to be used is mainly
dependant on the board thickness.
determine which of the three holes lines up
closest to the centre of the board
(example Fig. 3 shows 6mm dowel
required),
NOTE:
diagram for illustrative
purposes only.
When the dowel size is decided (in this example
8mm), slide the 8mm depth stop onto the
equivalent drill.
The position of the stop is determined by the type
of joint and the length of the dowel used. in this
example, edge to edge, the dowels will be
required to be inserted equally into both pieces to
be joined. Measure the length of the dowel
(average = 37mm), divide by 2, = 18.5.
Insert the drill into the 8mm guide so that 19mm
19mm
protrudes through the jig. (Fig. 4), this ensures the
dowels will not bottom and prevent the boards
from meeting when joining together.

Slide the depth stop up to the jig body without
moving the drill, lock in position, check the drill still
protrudes 19mm, if not readjust.

Place second board onto jig (Fig. 2),
ensure as before, the board edge is
tight against the jig and clamp
block, also line up the ends and
secure with upper clamps.

Fit the drill assy into the drill chuck
and tighten securely, select a
suitable speed for the material being
drilled.
Switch ON and carefully offer the drill
into the 8mm guide bush, proceed to
drill the dowel hole.
To prevent the drill from binding in the
hole and enlarging the diameter, thus
making a loose fitting dowel,
repeatedly withdraw the drill
sufficiently to clear away swarf.
Repeat the above procedure for the

other board through the corresponding guide bush.
Further holes will need to be drilled along the full length of boards to be fitted, the
distance between hole centres will need to be
calculated and marked off on one board only.
A simple method of spacing the holes can be
carried out using an off-cut of wood or similar as
Spacer
Dowel
a spacer. This can be carried out as follows.
1. Loosen the upper and lower clamps on
the jig, slide the jig along the boards.
2. Push a dowel into one of the drilled holes.
3. place the spacer against the dowel and
slide the jig back against the other
side of the spacer.
4. Secure the jig with the upper and lower
Fig. 6
clamps. Remove the spacer.
5. Drill both holes as before.
6. Repeat steps 1 - 5 until all holes are drilled.
Alternatively, once the hole positions have been marked, loosen the top and bottom
clamps on the jig, do not loosen the clamps on the clamp block.
Slide the jig along to the next position, secure in place with the upper and lower clamps.
Proceed to drill both holes as before.
Continue until all holes are drilled.
IMPORTANT When moving the jig position, at all times, one set of clamps must be holding
the boards together to prevent movement and misalignment of the dowels.
