The mortise gauge is a special
type of marking gauge and it
is used to mark wood so that
a mortise can be cut into it.
It is a compass with a
beam and sliding sockets
for dividing circles
The name comes from its "F" shape. The
F-clamp is similar to a C-clamp in use
cramp is often used instead when the tool is
for temporary use for positioning
A File Is
Used To cut
A long-bladed hand
tool with a beveled
cutting edge and a
handle which is
struck with a
hammer or mallet,

A saw is a tool consisting
of a hard blade, wire, or
chain with a toothed edge.
It is used to cut through
relatively hard material,
most often wood. The cut
is made by placing the
toothed edge against the
material and moving it
forcefully back and forth.
This force may be applied
by hand, or powered

It is ideal for box construction and is suitable for use
with natural woods such as pine and mahogany or
even manufactured boards such as plywood and MDF.
The joint is strong especially when used with a good
This a good example of a ‘finger’ or ‘comb’ joint.
A Finger Joint (sometimes called a comb
joint), is created by accurately cutting
out a series of steps on the ends of two
pieces of wood. Alternate sections are
then removed so that the two pieces fit
together as shown here.
This type of joint has a wide range
of uses and is particularly useful
when manufacturing furniture
A Tri Square and a marking knife are used to mark
the lines at the ends of the mortise.
The stock of the mortise gauge is pressed against
the side of the wood.
The Mortise Chisel is then used
to break the surface of the waste
wood by gently tapping the
handle with a Mallet.
Marking knife is used to produce a precise line, with the aid of a
Tri Square . A pencil can then be used make the line stand out.
The Mortise Gauge is used to mark the size of the Tenon.
The ‘DOVETAIL JOINT’ is very
strong because of the way the ‘tails’
and ‘pins’ are shaped.
Used in box constructions such as
drawers, jewellery boxes, cabinets
and other pieces.
It is a difficult joint.
They can be very impressive.
The box shown here is particularly strong
due to the dovetail joints at its’ sides.
CROSS HALVING JOINTS
They are used whenever
it is necessary to join
two pieces of wood that
cross over each other.
Using this would joint
would create a ‘+’ or a
‘X’ shape with two
pieces of wood.
These joints are used when a light frame is needed and
strength is not the main requirement.
PLAIN BRIDLE JOINT
Using this would joint would create a ‘T’
shape with two pieces of wood.
ANGLED BRIDLE JOINT
Using this would joint would create an ‘L’
shape with two pieces of wood.
A Mitre Joint is used where two pieces of wood need to be positioned
next to each other at exactly 90o. A 45o cut is made on either end and
when they are placed against each other, a 90o corner is achieved.
They are temporary joints although
many are used to permanently join
