Q

Comb joint

A

Used for boxes and carcasses
interlocking fingers which fit tightly
together and are reinforced by glue

Best created using a router jig on
natural or manufactured timbers or
using a laser cutter on some materials

Q

Dovetail joint

A

Used for cabinets and drawers
high level of skill
but can be cut fairly easily with a router and jig strength
relies on interlocking fingers and
accurate marking and cutting
• The dovetail shapes means
that these joints have superior
directional strength

Q

Housing joint

A

Used in shelves and dividers cut through one
piece of timber which houses
a second perpendicular piece
• It is fairly strong, when supported
with glue but can be used without
glue to create sliding parts

Q

Half lap joint

A

two overlapping materials glued together
• Used in picture frames, doors and cabinet making
• Quick and easy to make but
not particularly strong
• The shoulder helps resist
diagonal distortion

Q

Dowel joint

A

quick, simple and effective
method to join a variety of materials
• Used in both frame and carcass construction, flat-pack
furniture and to reinforce edge to edge joints
• Holes are machined easily with a drill and jigs can
be used to speed up the process further
• Suitable for use in natural timbers

Q

Mortise and tenon

A

heavy duty joint used in load
bearing timber frameworks
• With high shear strength, it’s used
in traditional building construction
and frames for tables and chairs
• The tenon may be glued or pinned in place.

Q

Finger/comb

A

Interlocking fingers increase surface
area for gluing
• Tight fit between fingers increases
strength
• Fingers create a repeated pattern
that is considered aesthetically pleasing

Q

Woods screws

A

different lengths and widths,
with a variety of head shapes and finishes
• Most screws are made from mild steel and are then plated
in brass, zinc, chrome or another non-corrosive metal
• Screw heads are often countersunk so the screw hole can be
filled or plugged, others have a domed head which can make
a feature of the joint
• Screws are quick to install and can join dissimilar materials

Q

Heads and threads

A

most common type of screw is the Pozi-drive
• Philips and slot head screws also are commonly available
• It’s essential to choose a driver bit of the correct size and
shape to avoid damaging the screw, driver bit or workpiece
• Self-tapping screws don’t always need a pre-drilled pilot hole
and twin drive threads drive into timber in half the time

Q

Clearance and pilot holes

A

• Pre-drilled clearance and pilot holes reduce the risk
of wood splitting when a screw is inserted
• Pilot holes allow the core of the screw
to pass into the material while the
thread bites into the sides
• Clearance holes allow components
to drop in and out without friction
• Clearance holes are required
when using nuts and bolts
