There are many wood joints available to make,
joints are used to build strength into products.
The joints below are the joints that are commonly
used in schools. Note only glue is used to join
these joints together.
| 1. Butt joint
A very simple joint but it
is also very weak. They tend to be used
for making picture frames, corner pieces
and nails are often used to strengthen the
joint.
|
 |
| 2. Mitre joint
Mitre joints are often
used to produce the corners of picture frames
and boxes. The mitre needs to be cut at
a 45 degree angle, this is often used with
a mitre saw that can cut at many different
angles. |
 |
| 3. Halving joint
There are many versions of
the halving joint but they all involve removing
half of the wood from each piece using a
saw or a chisel. This joint is often strengthened
with dowel.
|
|
| 4. Mortise and Tenon
This is a very
strong joint. The joint is split into two
parts one part is the tenon named after
the tenon saw, the other part is the mortise
which is named after the mortise chisel.
Within industry the joint is milled using
a milling machine.
|
|
| 5. Dowel joint
This joint is quite
easy to make, it consists of drilling accurate
holes in both sections of wood and joining
them with dowel pegs. Within in industry
this is often used to construct flat pack
furniture. |
|
| 6. Lap joint
This joint is only slightly
stronger than the butt joint. There is however
a bigger surface area for gluing. This joint
is often strengthened with nails.
|
| |
| 7.Housing joints
This is just
a simple slot cut into one piece of wood
to increase the glue area. This is often
done with a router and works very well in
MDF.
|
|
| 8.Finger joint
This is the strongest
joint on this page, the only joint that
is stronger is the dovetail joint. The finger
joint can be difficult to make but looks
very good. It has a lot of surface area
to glue together.
