The Anatomy of
a Precision Jig
12
13
It took five years to complete the development of the Leigh
FMT! Early on it became evident that to achieve the precision
required by demanding woodworkers, this new jig would be
costly to produce. After numerous prototypes and test sessions,
the final FMT includes 88 parts that are either extruded, die
cast or injection molded, each requiring a custom die or mold.
In addition, eighteen components are CNC machined to very
precise tolerances. For finer detail, read the following:
• The clamp plate (1) is a rugged five hollow 6063-T5 aluminum extrusion, CNC
machined flat with a special non-slip finish. Its built-in adjustment
parallels the plate to the table-guide alignment and is factory set to plus or
minus .0015" over 13"! The clamp plate can be angled up 30º (2) and features
an adjustable stop screw for setting 90º.
• Clamping is provided by two powerful 3" capacity clamps featuring Leigh’s
Cam-Action Speed-Clamps and die cast ZA12 alloy rocking arms (3). Multiple
clamping positions are machined into the clamp plate for all mortise and
tenon work pieces.
• The die-cast aluminum tenon side stop fence (4) can be angled up to 45º left
or right, or preset square as required.
• The die-cast aluminum vacuum box has a 1 1/2" O.D. dust removal port (5).
• The table (6) is made of 1/2" Mic 6 plate, a special proprietary brand of
continuously-cast aluminum plate that is rigid, flat and stress free. It comes
from the foundry milled flat both sides to a tolerance of +.005 thickness and
.015 flatness over a 12-foot span! (The FMT table is only 16 1/2"!) The table
is then CNC machined both sides with the channels, recesses and openings
required for the FMT.
• The table moves front to back and left to right and locks in any position by a
flip of the table clamp lever (7). This lever operates a sophisticated clamp
system incorporating five more CNC turned brass and steel parts making it
highly efficient, convenient and easy to use (8).
• Under the table are two more CNC milled 6005A-T5 aluminum extrusions (9)
which provide both jig structure and table movement. UHMW strips act as
slide bearings between these components and to the underside of the table.
Delrin (Acetal) V-blocks on ground steel pins in machined V-grooves ensures
true table alignment in both x and y axes.
• A retractable sight (10) made of Fortron PPS, a high-tech ultra rigid filled resin,
is used to perfectly centre the table opening (11) over the pre-marked joint
positions. Table limit stops (12) are adjustable for precisely controlled positioning of the table in both directions when needed.
• Each joint guide (13) snaps into the table guide recess which perfectly aligns
with the cutter opening (11) and the right side pin track (14). Guides and pin
track are injection molded from Delrin for durable and smooth operation.
• The router sub-base (15) is CNC machined from 6061-T6 tempered aluminum.
The two tapered stainless steel guide pins (16) threaded through brass bushes (with neoprene bearings) are precision CNC machined to match. These pins
ride in the pin track on the right (14) and against the joint guides on the left
(13) and provide the fine adjustment for perfect joint fit.
• Teflon pads (17) on the table and on the router sub-base make routing very
stable and smooth.
• The Leigh universal router sub-base mounting system (18) works with
virtually any plunge router, but the router in most instances can be removed
and refitted to the sub-base in under two minutes. A dedicated router is not
necessary for this jig.
“Leigh’s new Frame Mortise and Tenon Jig is a tour de force
of design.” – Ernie Conover, Conover Workshops

How the Leigh FMT Works
The FMT works on a very simple concept. The Leigh router sub-base rides on the jig table and
has two pins projecting downward. The right hand guide pin runs in a track in all routing
procedures. The left hand pin steers the router on the joint guide. The cutter, centered between
the two pins, cuts the mortise and tenon.
Joint Guide
Track
Routing Tenons
The cutter is lowered down to the required tenon
shoulder depth and the left hand guide pin is
moved around the outside of the joint guide.
Thickness and width of the tenon is controlled by
the size of the guide.
TENON
Sub-Base
Routing Mortises
Joint Guide
The left hand guide pin runs in the joint guide
mortise slot. The mortise is formed by progressively plunging the cutter and routing side to side. The
two guide pins and cutter are in perfect alignment
in the sub-base. The joint guide mortise slot controls the mortise size.
Track
MORTISE
Adjusting Joint Tightness
The guides are carefully designed to ensure the
adjustment range of the guide pin takes up all
normal manufacturing tolerances in cutter diameters and router run-out to produce a perfect joint
fit (1). Raising the tapered guide-pin will allow the
pin and cutter more movement to make a wider
mortise and smaller tenon for a looser joint fit (2).
Turning the pin down causes a tighter joint fit (3).
(Proportions and angles in these illustrations are
exaggerated for clarity.)
The guide pin (4) is controlled by a graduated
knob (5). The number of turns are indicated by
steps in the height washer (6). This allows for
recording of settings for future use. Turning the
guide pin knob just one-eighth of a turn adjusts
the joint glue line gap by a tiny one thousandth of
an inch! Yes, 0.001" (0.025mm) accuracy!

6. Height Washer
“...a test cut establishes the exact settings of the adjustable pins, after which either mortise or tenon can be cut with extreme
accuracy...the positions of the adjusting knobs can be recorded so that for each guide the setting can be dialled straight away.”
–Ron Fox, Routing Magazine (UK)

How to Rout Mortises and Tenons
The Tenons
Outrigger Bars
1. Mark the center of the tenon
on one end of only one workpiece with a cross.
2. Select the matching cutter and
guide. Install the cutter in the
router and snap the joint guide
into the guide recess.
3. Extend the table sight.
4. Clamp the tenon piece against
the side stop fence.
5. Move the table to position the
table sight over the cross lines.
6. Centre sight over the cross lines.
The FMT comes standard with
two outrigger bars which are
quickly attachable to slots in
both ends of the clamp plate.
Simple shop-made outrigger
beams of lightweight plywood
are attached to the bars with
fasteners provided.
7. Lock the table and retract the
table sight.
8. Place the router/sub-base on
the table and lower the cutter to
the required tenon shoulder depth.
The Mortises
1. Mark the mortise center positions on one mortise workpiece only.
2. Remove the router and extend
the sight; move the mortise piece
left and right to sight for center
and clamp it in place.
9. Rout the tenon. All other
similar tenons may now be
routed without having to mark
or sight the tenons, or to
remove the router from the jig.
3. Place the router/sub-base (not
shown) on the jig and plunge rout
the mortise. See sidebar for positioning the workpieces for the
remaining mortises.
“The FMT allows precise adjustment of fit and the cutting of mortise and tenons and
any angle. Once a precise fit is obtained, the joint can be repeated indefinitely
independent of stock thickness.” – Ernie Conover, Conover Workshops
When sighting mortises, either
clamp on workpiece stop
blocks or make pencil reference marks on the outrigger
beam (circled). These stops or
reference marks enable the
routing of all similar mortises
without having to mark or
sight the mortise positions or
remove the router from the jig.
Now, routing all the tenons
and mortises for any number
of identical frames requires
making only a few pencil crosses and picking up the router
just twice.

The Leigh FMT Creates Beauty with Inner Strength
The traditional mortise and tenon is indisputably the
strongest way to build frames for fine furniture. No other
method can produce the 92 mortise and tenon joints used
in these four pieces of furniture as precisely or as quickly!

Innovative FMT Features That Benefit You
Perfect Multiple Joints!
Perfectly aligned multiple mortises
and tenons are quick and easy to set
up on the FMT. This precision and
repeatability is made possible by the
adjustable table limit-stops (circled).
One pair of stops and a fixed stoppost limit left-to-right table movement; the other two stops
limit front-to-rear movement. With each tenon position
sighted and limit stops set, you’re ready to rout double,
quadruple or even triple mortises and tenons.
Quadruple Joints
Clockwise from left, examples 1 to 4 below show how a
quadruple tenon is routed.
Wider or Narrower
Joints
1
It is faster and easier to
have the correct size joint
guide, however if you don’t,
the left-to-right limit stops
combined with the rapid
2
acting table movement make
3
it simple to quickly rout
mortises and tenons either
narrower or wider than the
available joint guide.
The photo above shows that with a 1 1/2" guide (1), a simple two-step procedure is used to rout either a 1" wide joint
(2) or a 2" wide joint (3), or any width you choose from; up to
nearly two times the guide size or as narrow as two cutter
diameters.
Bonus Feature — Doweling!
1
Rout the rear left tenon.
2
For perfectly spaced holes in mating components just engage
the guide pin in the ends of a mortise guide slot and plunge
the cutter. The two-way table movement and the table limit
stops make this feature extraordinarily versatile.
Move table to the right;
rout rear right tenon.
4
Move table to the left; rout
front left tenon.
3
Move table forward; rout
front right tenon.
From the above sequence, it is also easy to see how double
joints are routed – either side by side or in line.
Triple Joints
Triple joints are routed just
like quadruples. However,
when the table is moved to
the left or right, a small stop
block is placed between the
front-to-rear limit stop and
post (circled), to position the
table for routing the third
mortise and tenon.

It’s easy to rout perfectly fitting joints smaller than the guide’s
nominal size simply by using two different-sized cutters. This
feature has significant advantages. For rapid production it is
much more efficient to rout tenons with the largest cutter possible. The mortise must be routed with a mortise-sized cutter
but in many cases the tenon does not.
For the mathematically inclined, any two cutter diameters
which add up to two times the nominal guide size will produce
a joint the size of the smaller cutter. Bear in mind the maximum usable cutter diameter with the FMT is 1/2" (12mm).
As you will see from the charts on pages 12 and 14 this
procedure enables fast routing of joints smaller than 1/4"
(6mm). There are many applications in smaller scale pieces
such as small cabinet door frames, where the rapid production
of 3/16" or even 1/8" joints will be invaluable compared to the
alternative methods.
The diagram above illustrates routing a 1/4" joint using a
3/8" guide (not shown), 1/4" mortise cutter and 1/2" tenon
cutter. The result is a perfect 1/4" mortise and tenon, 1/8"
smaller overall than the guide size.
Incredible Miniature Joints are Easy!
You can quickly rout joints not only smaller than 1/4" but also miniature
mortise and tenons, all with adjustable fit, just by using larger tenon cutters.
These examples of miniature joints show the extreme versatility of the FMT.
The 7 1/2" ebony and holly ladder leaning against a 1/2" X 5" tenon has ebony
wedged tenons 1/16" X 1/8".
The matches have progressively smaller tenons mortised through other
tenons, featuring joints .040" X .095", .023" X .068" and .013" X .053" respectively. The smallest mortise
and tenon was routed with
.010" mortise and 31/64"
tenon machine tool cutters.
These matchstick joints actually creak when assembling!
And if you’re wondering
how pieces such as the
matches, miniature table
parts and some of the curved
workpieces are held in place,
here’s how: there are twelve
through-holes in the clamp
plate by which shop-made
auxiliary plywood plates,
blocks, and work-holding
fixtures can be attached
and used together with the
Leigh cam clamps. It’s all in
the easy-to-follow Leigh User
Guide.
Left: Whether it’s a 27” tall walnut night
table or a twelfth-scale miniature replica,
all of these mortise and tenons were
routed on the FMT.

“If you do even a small run of mortise and tenon joints, say for 4 or 5 cabinet doors, you’ll experience a significant time (and cost!)
savings. Imagine your savings over a year’s worth of work…“ –Carl Dugay, Canadian Woodworking Magazine
Inch Guides and
Cutter Selection
(see p.14 for Metric Guide and Cutter Selection)
When selecting cutters, note that each guide
will produce a mortise and tenon the same
size as the guide when using a single cutter
of that same size. For example, a 1/4" guide
and cutter will make a 1/4" joint, a 3/8" guide
and cutter will make a 3/8" joint and so on
for each of the four guide series for a total of
21 joint sizes.
You can increase the number of joint sizes
that can be routed by using two cutters with
the guide (as described in Production
Routing and Smaller Joints on page 11).
This gives you a further 47 joint sizes!
Note that in addition to the joint sizes
listed in the chart below, any mortise
length (tenon width) up to twice the guide
length can be easily achieved by using the
jigs quick acting table movement and limit
stops (see page 10, Wider or Narrower
Joints). And, by using combinations of
machine tool cutters, even more sizes of
small and miniature joints may be routed
(see page 11).
How to Use the Chart Below
The five standard 5/16" guides and sixteen
optional guides are color coded in solid color
blocks: eight 1/4", five 5/16", four 3/8" and four
1/2" guides. The further 47 joint sizes are listed
along the line to the left of each guide, shaded
in grey. Tenon cutters are featured in red.
Example: To rout a 3/16" x 1" joint, go down
the 3/16" mortise cutter column to 3/16" x 15/16"
(the nearest joint size). The mortise cutter is
3/16" and the tenon cutter is 5/16". Look along
the row to the right to find the 1/4" x 1" guide.

Router Selection
To achieve the full potential of the FMT, you must
have a 1/2" (12mm) plunge router. A 1/4" router can
only rout 1/4" joints and an 8mm router can only rout
8mm and some 4mm joints.
Look in the list to the right to locate your router. If
it isn’t listed you can still attach your router to the
Leigh sub-base, provided it has two fence rod holes
through the base with a diameter of at least 5/16" or
8mm (see diagram, above right).
Some routers are attached directly to the Leigh
sub-base with special Leigh screws that come with
the jig. The diagram of Porter Cable model 693 to the
right shows the screwholes used to attach the router
to the sub-base.
