INTRODUCTION

SUPERJIG-12-18-24 User Guide

Your New Leigh Dovetail Jig

Congratulations! You now own a most useful and versatile

dovetailing tool. The Leigh Superjig Dovetail Jig will help

you cut an infinite variety of joints, and all of its major func-

tions are described in detail in this user guide, plus there’s a

Quick Reference Guide that pulls out from under the jig.

Instructional videos of pertinent chapters are available online

on the Instructional Videos and User Guides page in the

Support menu.

We recommend that you first assemble and mount the jig,

carefully following the instructions in the first section of the

user guide. Then read the rest of the guide, following along

with the basic functions and principles of operation, before

you try to do any actual joinery routing. By all means, cut a

few practice joints in scrap boards before you use the jig to

rout a precious hardwood work piece!

If you have questions not answered in this user guide, please

call the Leigh customer support line: 1-800-663-8932

or email Leigh: [email protected].

But remember: “If at first you don’t succeed, read the instruc-

tions!”

*See Appendix IV – Customer Support

Important! Inches and Millimeters

The Superjig can be ordered in inch or metric versions.They’re

identical except for the calibration scales. This Leigh English-

language user guide show measurements in both inches and

millimeters, with “inches” first, followed by “millimeters” in

square brackets.

Example:

3⁄4"x 51⁄2"x8" [20x140x200mm]

Do not be concerned if the inch/millimeter equivalents are not

exact. Just use the dimensions which apply to your jig.

Where finger assembly scales overlay an illustration, the “inches”

scale will be at the top, the “millimeters” scale will be at the

bottom. Only the front “active” half of the scales are illustrated.

For clarity, setting positions are indicated with a red line in the

user guide only. On the jig, the lines are black.

Glossary of 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 quite frequently throughout the user guide,

and you will soon get used to them.

The Leigh jig’s guidefinger assembly can be in any one of four

joint modes, depending on what type of joint and which part

of the joint you are routing. Each finger assembly scale has it’s

own mode icon , identifying that joint part. You will also find

the joint mode icon in the top left corner of most illustrations

, indicating which finger assembly mode to use.

Sometimes a joint mode icon will be used to identify a board .

These are the four joint mode icons:

TD Tails

(tails for through dovetail joints)

TD Pins

(pins for through dovetail joints)

HB Tails

(tails for half-blind dovetail joints)

HB Pins

(pins for half-blind dovetail joints)

INTRODUCTION SUPERJIG-12-18-24 User Guide

Which Way Round Should the Board Go?

As virtually all dovetail joinery is used to make boxes,

drawers and chests etc., we devised these simple (and

hopefully intuitive) icons to indicate which side of a

board faces inwards or outwards on the finished “box”,

and which side of the board faces outward (toward

you, the operator), when it is clamped in the jig.

The following symbols indicate:

eThis edge against sidestop

fThis edge against sidestop

Sawcut allowance

 Caution: use special care for this

operation

 Numbered References in text

This icon oindicates the “outside”

of a board. All through dovetail

pin boards are mounted in the

jig with this “outside” face away

from the jig (toward you, the

operator).

This icon iindicates the “inside”

of a board. All half-blind pin and

half-blind tail boards, and through

dovetail tail boards, are mounted

in the jig with the “inside” face

away from the jig toward you,

the operator.

This icon jindicates boards that

are mounted both ways e.g. sliding

dovetails and box joints.

Dotted line icons

indicate the

“other” side of the board in the

illustrations.

Dust-Free Routing!

The revolutionary Leigh VRS Vacuum & Router Support* provides almost 100%

dust and chip collection as well as amazing full width router support. The VRS

is a must-have for all Leigh dovetail jig owners.

*US patent: USPN 7,507,060 B2 UK patent: GB2446909 Canada Patent No. 2,611,233

Here’s How It Works

The VRS is mounted on brackets on the front of the jig and the router is sup-

ported by the finger assembly and the full width beam of the VRS. The vacuum

chute rides under the router support beam. Control arms, attached to the

vacuum chute, surround the router. These arms are adjustable to accommodate

any router base. As the router moves across the joint, the vacuum chute glides

effortlessly from side to side on nylon rollers. The chute is always in perfect

position to catch the dust and chips thrown out by the router bit. Chips and

sawdust are drawn into the vacuum chute and down through the vacuum hose.

Each VRS comes complete with two adaptors to fit all popular vacuum hose

sizes and the VRS can be used with a small shop vac or a large built in system.

The VRS is easily attached without jig modification. Each VRS comes complete

with all mounting hardware needed for any Leigh 24" D-Series jig, all Super

Jigs or the earlier model Leigh D1600.

VRS Vacuum & Router Support Features

• Full width router support

• Easy on Easy Off. Powerful rare earth

magnets secure router support beam

• Park the router when not in use

• Vacuum box glides effortlessly under

router support beam

• Control arms position vacuum box

• Control arms adjust to any router

• No hoses to obstruct view

• No jig modifications necessary

• Models for all Leigh jigs

• All mounting hardware included

• Adapt to any hose size

The dust chute rides beneath the

router support beam. Control arms

ensure accurate positioning of the

chute and the size and shape of the

chute ensures total waste collection

regardless of bit size or joint type

being routed.

The VRS will work with almost any

shop vac or large vac system. Two

adaptors are included with every

VRS to handle hose sizes from 1"

to 2-1/2".

The VRS is a full width router support.

When the work piece has been routed

on one side of the jig, the router can be

effortlessly moved to the other side of

the jig and parked while the work piece

is being changed. There is no need to

remove the router from the jig.

Because the vacuum box is always

in perfect position relative to the

router bit, the dust and chips com-

ing off of the router bit are auto-

matically drawn into the chute and

vacuum hose.
