Units of Measure

IMPORTANT! INCHES AND MILLIMETERS

Text and illustrations in this English language user guide indicate dimensions in both
inches and millimeters, where applicable, with “inches” first, followed by “millimeters” in
square brackets, i.e. 1/2" x 2"[12,7mm x 51mm].

Don’t be concerned that the inch/millimeter equivalents are not mathematically
“correct”.

Bit Specifications

There are two bits used with the TD330 Through Dovetail Jig. Your new jig is shipped
with a 1/2" 2-flute, carbide tipped straight bit, and a 1/2" 8º carbide tipped 2-flute
dovetail bit. You may also use a 1/2" spiral upcut bit in high speed steel or solid carbide.

Router requirements: The Leigh TD330 Through Dovetail Jig requires a router with a

1/2" collet.

Clamping

The TD330 jig is clamped to the workpiece using two user supplied quick grip clamps,
or similar.

Marking the Boards

Before mounting and routing the
boards, mark them as follows. A
“P ” and a “T ” are marked on
the boards to indicate which
is the pin board and which is
the tail board. The marked face
indicates it is an outside board
and always faces away from
the jig and outwards on the
assembled box.

 Never drink alcohol or

take medications that can cause

drowsiness while operating a router.

Always disconnect the power



source before installing bits, guide

bushings or making adjustments. Before
reconnecting the router to the power
source, make sure the bit and collet
revolve freely with and without the
guide bushing in place.

After routing, wait for the bit to come
to a complete stop before removing the
router from the jig.

Do not tilt the router. Keep the

The e10 is installed in the base of
the router and the guide bushing

inside of the router base.

bushing steers the router and the
bits in and around the openings of
the template.

A

B

3-5 Joint Fit Adjustment The

Leigh eBush barrel A is elliptical,
unlike plain circular template guide
bushings B. When the e10 is rotated,
the effective diameter of the barrel
changes, allowing fit adjustments as
small as 0.001"[0,025mm]. The e10
eBush is included with the jig.

Note: The elliptical barrel of the e10

shown in these and the following
diagrams is exaggerated for clarity.

3-6 The effective diameter of

the e10 is 5/8"[15,9mm] at the
10 position. Rotating the eBush to
the 0 position reduces the effective
diameter by 0.020"[0,5mm].

3-7 One increment of the eBush

changes the joint glue line by

0.002"[0,05mm]. Half an increment
changes the fit by an incredible

0.001" [0,025mm]. A proper fit will
be established with one or two test
cuts.

3-8 Test routing always starts

with the eBush set at 5 This

allows adjustment for a tighter or
looser fit. Turning the eBush toward
the 10 position A results in a tighter
fit. Turning the eBush toward the
0 position B results in a looser fit.

Be sure to retighten the eBush
nut after each adjustment.

Mounting
& Assembly

The following steps will show
you how to prepare the beam
and assemble your Leigh TD330
Through Dovetail Jig.

You will need:

• A workbench with vice or a
portable workbench

• 2 pieces of 3/4"[19mm] MDF to
make a beam 1-1/2"x 3-1/2" x
19" [38mm x 90mm x 483mm]

• Router with 1/2" collet

• Electric drill, preferably bench or
pedestal, but handheld will work

• 3/32" drill bit

• Two Quick-Grip clamps

• Square

• Ruler or tape measure

• No.2 Phillips screwdriver

• Wood glue

Note: The finished beam must be

1-1/2"[38mm] thick.

4-2 Making the Beam We

recommend laminating two pieces of
MDF: 3/4"[19mm] x 3-1/2"[90mm]
x19"[483mm]. Clamp the glued
pieces together and set aside to dry.
Be sure the top edges are flush and free
of glue residue. Alternate materials
may be used, eg, a common 2x4 in
North America, however the finished
thick ness must be 1-1/2"[38mm].
See Step 4-14 for special instructions.
If you are making dovetails using
narrow boards, see Step 5-66.

4-3 One side of the template is

used for routing pins, and the other
side for routing tails.

screwdriver to attach the template
with the included screws.

Do not use a power drill, as this



may overstress the template.

4-14

Make sure the positioning
ridges (see Step 4‑5) are held against
the beam while tightening the
screws.

4-15 Alternatively, you can use a

straight, flat 19"[483mm] piece of
common 2x4. Since a 2x4 has slightly
rounded corners, some preparation
is required. Note: the finished
thickness must be 1-1/2"[38mm].

Use a table saw, router table or
jointer to skim o the top surface of
the 2x4. Now go back to Step 4-4
for the rest of the beam preparation.

4-16 Prepare the Beam

25

To prevent tear-out of your good
material, grooves must be routed
in all template openings, on both
sides of the beam, as shown in the
following steps.

Preparing the beam is particularly
important when using a common
2x4 because its side grain will tear
out badly.

4-17

Turn both side stops until the
straight edge is vertical and facing
toward the middle of the beam.

4-18 Depth of Cut

Select a board
at least 13-1/4" [330mm] wide and

Length is not important as long as it
can be clamped safely in the vice.

Mark a depth of cut line 3/4" from

board. Clamp the board in the vice
with the depth of cut line facing you.

Board widths indicated in the EXACT column of the
chart will produce half‑pins at each board edge. Board widths may be increased by 3/8"
[9,5mm] resulting in larger, but equally sized pins at each board edge. Similarly, board
widths may be reduced by a maximum of 1/8" [3,2mm], resulting in smaller but equally
sized pins at each board edge. Narrower widths may result in very small and weak pins at
the edges of the pin board.

Symmetrical

Full size

pins and sockets

Width specified in the board width chart
results in half size pins and sockets at
each edge of the board.

Reduced size pins and sockets

When a symmetrical board width is
reduced, the joint will have smaller, but
equal sized pins and sockets at each
edge of the board.

Small pins can break easily

When the board width is reduced
further, the result is very narrow and

Prepare four similar boards 3/4"
thick × 7-1/2" wide by 12" long
[19mm×191mm×305mm], and two
test boards, 3-3/4" [100mm] wide
and the same thickness.

Note: Boards of different thicknesses
may also be joined.

The two test boards are used to
establish joint fit before making the
box.

Mark the outside face of one test
board with a “T ” (tail board) and
the other one with a “P” (pin board).

so, install the e10 guide bushing in

the board toward the side stop B.

Make a Climb Cut

When
routing pins, you should always start
with a shallow climb cut as this will
produce a clean shoulder A.

A climb cut may pull the jig to the
right, so be sure to hold it firmly. Start
on the right of the template opening
and make a shallow cut as you move
the jig to the right.

After making the climb cut,
rout out the rest of the wood between

along the width of the board.

Be sure the guide bushing touches
both sides of the template opening.

6-37 Joint Fit Adjustment

With the marked sides facing out,
assemble the test boards. If the joint
is too loose, use the pin wrench and
turn the eBush to a higher number

and rout a new pin board.

One or two test

cuts should produce the proper fit.

Re‑tighten the eBush nut after
each guide bushing adjustment.

If the edges of your joints are not flush,
this could be due to bit concentricity
issues.

The pin board edge that goes against
the side stop might need to be raised

or lowered B slightly.
