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: help@leighjigs.com.

Are there operational differences between the F3 and F18/24? 

No. While the F18 and F24 are illustrated for most of the proce- illustrated in each step are identical whether performed on the 

dures in this guide, the differences between the F3 and the F18/24 F3/F3M, F18/24, or F18M/24M. Icon types for template pin 

do not affect the operational instructions. Movements and settings positions are the same on all templates.

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"x5 1 ⁄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 ➀ 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 ➁. 

When calibration marks on the support brackets ➂ are highlighted, 

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 

Inactive scale upside down. 

and 

Active scale right side up.

TERMINOLOGY 

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. 

jBoards 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 

iInside of board. All half-blind box joints are clamped in the 

jig with the inside i 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: 

eThis edge against side stop 

fThis edge against side stop 

As above, other side of board

Assembly and Mounting 

Before you begin mounting the Leigh Finger Joint Template to your Leigh Jig, make sure you have received the model ordered 

(Inch or Metric), and all the necessary parts. 

1. 1 e7-Bush incl nut (F3 only) 

1 e8-Bush incl nut 

1 e10-Bush incl nut 

1 Pin Wrench 

1 User Guide 

2. 1 Template “inch” assembly, 

or: 

1 Template “metric” assembly 

If any of these items are missing, please 

notify your supplier or Leigh Industries 

immediately. 

Except for the scale thumbscrews (packed 

in a bag attached to the template), your 

Leigh F-Template comes fully assembled 

and requires only mounting and indexing 

to your Leigh jig. This procedure is 

critical to the accuracy of the finished 

joinery, so please follow the mounting 

instructions carefully.

Read and follow the recommendations in this chapter. 

2-1 Read the owner’s manual that came with your router. It is 

essential to understand the router manufacturer’s instructions 

completely. 

2-3 Never drink alcohol or take medications that may cause 

drowsiness when you will be operating a router. 

CHAPTER 2 

Using Your Template Safely 

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. 

2-4 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.

2-5 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. 

1 

USING YOUR TEMPLATE SAFELY 

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. 

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. ■

OPERATION CONCEPTS AND BASIC TEMPLATE FUNCTIONS 

F18 

F3 

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. 

3-3 ...the mating rear side stop, depending on which procedure 

is to be used. 

1 

2 

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 ➀. Note that the template is close 

to the scale ➁. 

3-2 Clamp your work pieces against the front side stop or... 

3-4 The template control pin engages the template to the template 

bar using precisely positioned holes ➀. 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 

2 

3-6 In this illustration, the template is moved to the right by 

half the comb pitch and positioned by the template pin ➀ to rout 

the mating half of the joint in 3-5. Note the increased gap between 

the scale and template ➁. ■ 

1


4-1 Unlike plain circular template guidebushes ➀, the e-Bush is 

elliptical ➁. 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.

.500" .480" 

2 1 

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 ➀ is ~.500", and minor axis ➁ ~.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.

Guidebushes and the Unique 

Leigh e-Bush 

1 

? ? ? ? ? 

4-2 Joint Fit and Joint Pitch Box joints routed with standard 

sized straight bits ➀ and standard sized guidebushes ➁ against 

straight guide surfaces ➂ on pitch centres exactly two times the bit 

diameter ➃ 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”. 

1 2 

4-4 Here’s how it works. In normal use, the operator does not 

rotate the router more than a few degrees either way ➀. In fact, 

because of potential bit-to-bush eccentricity problems it is advisable 

to minimize router rotation on jigs ➁.

GUIDEBUSHES AND THE UNIQUE LEIGH e-BUSH 

2 

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 ➀. 

2 

+ - + - + 

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. 

4-9 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. ■

- + - + - 

4-6 With the e-Bush ➀ turned to “10” in the base ➁ 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. 

2 

= = = = = 

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.

CHAPTER 5 

Board Width Selection 

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. 

1 

5-3 Symmetrical joints are essential for half-blind corners ➀. 

However, ordinary box joints may be asymmetrical and look 

okay ➁. 

2 

1 

2 

4 

3 

5-2 Symmetrical joints have pins ➀ on both side edges of one 

board and sockets ➁ on both side edges of the mating board. 

Asymmetrical joints have a pin ➂ on one side edge and a 

socket ➃ on the other side edge of each board. 

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.
