Your New Leigh M2 Attachment
Congratulations! You now own the world’s
only jig for routing multiple mortise and tenon
joints; one of the most difficult joints to hand-
cut is made simple with the M2.
The M2 is an optional attachment for the Leigh
Dovetail Jigs: 24" [610mm] models D1258,
D1258R, D3, D4 and D4R. Most illustrations
in this guide show the M2 mounted on the
D4 jig but the instructions are identical for
all the D4R and all earlier D series jigs.
Important: Inches and Millimetres
Leigh makes the M2 attachment in two models;
inch or metric. Text and illustrations in this
Leigh English-language user guide indicate
dimensions in both inches and millimetres.
Dimensions are indicated in text and illustra-
tions with inches first, followed by millimetres
in square brackets.
Example:
3⁄4" x 51⁄2" x 8" [20 x 140 x 200mm]
Do not be concerned if the inch/millimetre
equivalents are not always exact. Just use the
dimensions which apply to your jig.
Where finger assembly or template scales
overlay an illustration, the inches scale
will be at the top, the millimetres scale will
be at the bottom. Only the right “active” half
of the scales are illustrated. Setting positions
are indicated in this guide with a red line.
On the jig, the lines are black.
General views of the scales will usually
show inch markings.
We recommend that you first mount the M2
on your Leigh Jig, carefully following the
instructions in the first section of this manual.
Then read the rest of the manual, 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 M2
to rout a precious workpiece!
If you have any questions that are not answered
in the manual, please call the Leigh customer
support line.*
