Introduction F3, F18 & F24 FINGER JOINT TEMPLATES USERGUIDE
FOREWORD
Your new Leigh Finger Joint Template
You now own a superb finger jointing system. The
Leigh Finger Joint template and adjustable e-Bush
will help you rout finger or box joints with unique
adjustment for precise tightness of fit.
“Finger” and “Box”: Both words are used universally to title this simple but strong joint. As the first
machine-made joint, it’s old enough to be called
antique, so we have been even-handed in using both
terms throughout this guide.
We recommend that you first mount the template on
your Leigh Jig, carefully following the instructions
in the first section of the user guide. Then before
you try to do any actual joinery routing, read the
rest of the guide, following along with the basic
functions. By all means, cut a few practice joints in
scrap boards before you use the template to rout a
precious hardwood workpiece.
If you have any questions that are not answered in this
user guide, please call Leigh international customer
support: 1-800-663-8932
or email: [email protected].

TERMINOLOGY
Important: Inches and Millimetres
Because Leigh makes F3, F18 and F24 Templates in inch and
metric models, measurements in this user guide are shown in both
inches and millimetres. Dimensions are indicated with "inches"
first, followed by "millimetres" in square parentheses.
Examples:
1
⁄2"[12mm], or
3
⁄4"x51⁄2"x8" or longer [20x140x200mm].
Do not be concerned if the inch/millimetre equivalents are not
always exact. Just use the dimensions which apply to your jig.
Reading the Settings Illustrations
The F Template scales have dual markings for inch and metric.
Note: The scales on some templates may indicate a
1
⁄4"[6mm] size. This
comb size is only available on F1600 Templates.
The template scales are illustrated in a panel overlaying the main
illustration
~
when settings are specified in an instruction. The
inactive (upside down) part of the scale is not shown in the illustration.
Scale settings for instructions are shown with a
red line .
When calibration marks on the support brackets
are high-
lighted, they are illustrated in
red for clarity. On the jig, the lines
are black.
Scale Icons
The Leigh Finger Joint Template has two modes. Position the
selected comb to the front (toward you, the operator). This
places the

Which Way Round Should the Board Go?
We devised these icons to indicate which side of a board faces out
(toward you when it is clamped in the jig), and which faces are in
or out when assembled.
0
Boards are clamped in the jig both “face in” and “face out” for
alternate end cuts; e.g. all regular box joint ends are routed this
way
/
Inside of board. All half-blind box joints are clamped in the
jig with the inside
/
face away from the jig toward you, the
operator.
Shaded icons are on the other side of the board.
How to Read the Symbols
To help you understand the instructions and illustrations in this
user guide, we have used a number of international symbols, plus
a few special ones of our own. They are all explained below. You
needn’t worry about memorizing these symbols now because they
are repeated frequently throughout the guide, and you will soon
get used to them.
The following symbols indicate:

Using Your Template Safely
CHAPTER 2
Safety is not optional.
Read and follow the recommendations in this chapter.

2-4 Always disconnect the power source from the router when
fitting bits or guidebushes, or making adjustments.
Before connecting the router to the power source, make sure the
bit and collet revolve freely in all the areas you plan to rout, and
the bit does not touch the guidebush or jig.
2-1 Read the owner’s manual that came with your router. It is
essential to understand the router manufacturer’s instructions
completely.
2-2 Always wear approved safety glasses.
Protect yourself from harmful dust with a face mask.
Always wear hearing protection.
For complete comfort and convenience, get yourself a Leigh VRS
(Vacuum Router Support) to match your jig model.
2-3
Never drink alcohol or take medications that may cause
drowsiness when you will be operating a router.

2-5 Do not tilt the router on the jig.
Keep the router flat on the jig assembly.
Note: The optional Leigh VRS attachment prevents router tilting.
2-6 If you insist on removing the router from the jig while it
is still revolving, always pull it straight off the jig horizontally,
and do not raise or lower the router until it is completely clear
of the jig.
1
2-7 Do not rout at face level.
2-8 If you have never used your router before, be sure to follow
the router manufacturer’s instructions for its use. Make plenty
of simple open-face practice cuts without a guidebush before
you try to use the router on the Leigh jig. You must, of course,
always use a guidebush when routing on the Leigh Jig.

3-1 The active comb (the one you wish to use) is positioned
toward you at the front of the jig. Depending on the Template
model and comb size selected, the active comb may start at either
the right, or left-hand side of the jig. Combs that are the full
width of the template always start at the left side.
F18
F3
3-2 Clamp your work pieces against the front side stop or...
3-3 ...the mating rear side stop, depending on which procedure
is to be used.
3-4 The template control pin engages the template to the template bar using precisely positioned holes
~
. The active template
pin holes are always at the opposite end of the template , out of
the way of the router. Most illustrations will have an inset showing
the correct template pin hole position for the procedure.
1
3-5 Mating joints routed under the same comb have to be offset
to achieve correct joint alignment. On Leigh templates the offset
is achieved by moving the template left or right by half the pitch
of the comb. This movement is controlled by the template pin,
at the other end of the template
~
. Note that the template is close
to the scale .

3-6 In this illustration, the template is moved to the right by
half the comb pitch and positioned by the template pin

Guidebushes and the Unique
Leigh e-Bush
CHAPTER 4
9
4-1 Unlike plain circular template guidebushes ~, the e-Bush is
elliptical
. This innovation effectively changes the guidebush “active
diameter” when it's rotated, and provides benefits not possible with a
plain round guidebush. The F18 & F24 Templates include two Leigh
e-Bushes*: e-8 for
3
⁄8"[10mm] combs, and e-10 for 1⁄2”[12mm] comb;
the F3 includes those plus the e-7 for
5
⁄16"[8mm] comb.
1
2
4-2 Joint Fit and Joint Pitch Box joints routed with standard
sized straight bits
~
and standard sized guidebushes against
straight guide surfaces
on pitch centres exactly two times the bit
diameter
will guarantee a loose fitting joint. Bits, guidebushes and
templates are manufactured with necessary plus/minus tolerances
and the router will have some degree of run-out, or “wobble”.

4-3 The e-Bush (e-8 illustrated) fits to the router base or to a
guidebush adaptor in the base. See Appendix I. The ellipse or oval shape
major axis
~
is ~.500", and minor axis ~.480" [12,7 x 12,2mm].
Turning the e-Bush 90 degrees in the router base changes the active
guide size by .020"[,50mm] providing infinite adjustment and recordable settings for perfectly fitting box joints.
4-4 Here’s how it works. In normal use, the operator does not
rotate the router more than a few degrees either way
~
. In fact,
because of potential bit-to-bush eccentricity problems it is advisable to minimize router rotation on jigs
.

4-7 Turning the e-Bush to zero allows more side-to-side router/
bit movement, and more wood removal, producing larger sockets
and smaller pins, and thus a loose fit.
+ + +- -
4-8 A few trial-and-error test cuts and e-Bush adjustments will
allow you to establish the correct pin and socket sizes for a perfect
fit. Note: One division of the e-Bush changes the joint glue–
line interface by two thousandths of an inch, that is, 0.002" or
0,050mm.

4-9 When you have the best joint fit, mark the setting in pencil here. Different wood hardness may require slightly different
settings, so also note the wood species. Use the same bit next
time. N
4-5 Establish the orientation in which you normally hold and
operate the router on the jig. Now, up-end the router in the same
orientation. Make a small scratch line or permanent ink mark on
the router base or e-Bush adaptor at the 12 o’clock position
~
.

4-6 With the e-Bush ~ turned to “10” in the base the active
“diameter” is increased, allowing less side-to-side movement, and
resulting in smaller sockets and larger pins. A tight fit! Scale and
movement are exaggerated in this sequence of illustrations.

Board Width Selection
CHAPTER 5
11
Board widths are determined by the number of fingers you want in your design and whether the joint is symmetrical or
asymmetrical. This chapter makes it easy to determine appropriate widths for the Leigh Finger Joint Templates.
5-1 Board Widths and Joint Symmetry
Unlike the infinitely variable Leigh Dovetail Jig, a fixed template
cannot accommodate any width of board and still produce a neat
and even finish on both side edges of a joint. The boards must be
cut to specific widths, depending on the pitch of the comb.
5-2 Symmetrical joints have pins ~ on both side edges of one
board and sockets
on both side edges of the mating board.
Asymmetrical joints have a pin
on one side edge and a
socket
on the other side edge of each board.

5-3
Symmetrical joints are essential for half-blind corners ~.
However, ordinary box joints may be asymmetrical and look
okay
.
1
2
5-4
The comb pitches on the Leigh Finger Joint Templates
are all 2 times the bit diameter plus
1
⁄32"[0,75mm], so you
cannot simply use bit diameter to calculate board widths. See the board
width charts on Page 12. For symmetrical square joints use board widths in
red column. For asymmetrical square joints use widths in grey column.
