Frame Joints |
The Following images are of different timber joints used in furniture frame constuction.

Corner Halved JointThe Corner Halved Joint is one of the most simplest ways to join two pieces of timber together with minimum labour. This type of joint would be used for the corners of frames and supports both for internal and external application. Nails and glue would be added to support the hold of the joint.

Crossed Halved JointThe Crossed Halved Joint is like the Corner Halved Joint. A simple way to join two pieces of timber together except this type would be commonly used for support and frame construction supplying strength to the frame. It is also used for internal and external application. Like the Corner Halved Joint this one also requires glue and nails to hold.

Mortise and Tenon JointThis is a common joint used in the frames of such objects as tables. There is a common rule to creating this joint: the tenon(the piece cut to fit the second) should be cut at 1/3 of the thickness of the timber. This allows for the joint to be equally strong on all sides. This type of joint would also require glue to assist the hold.
|
Dovetail JointThe Dovetail Joint is one of the most complex and strongest joints available. The type of applications consist of draw frames and plinthes. It isnoted for not easily being pulled apart like other types of joints. There are many variations of the joint and the one shown is the most simplest and common. It is said to be inspired by the tails of the Doves. They also have an aesthetic strength. Glue would assist in the joints hold.
|
Finger JointThe Finger Joint is a much simpler version of the Dovetail Joint. It has similar qualities in strength although not as good as the Dovetail Joint. It also has aesthetic qualities and adds a beauty to furniture. Glue is also required to assist in the joints hold.
|
Butt JointThe most simplest form of joining two pieces of timber has to be the Butt Joint. It is not a very strong hold and can be easily pulled apart if required, but is used in less demanding applications. Nails and glue are a necessity to holding the timber together.

Widening Joints |
The following images are of different timber joints used in furniture construction to widen the timber. Most of the applications a widening joint would be used for is table tops. Using smaller widths in timber can be cost effective as wider cuts tend to be extremely expensive and harder to find
|
Dowel JointThe Dowel Joint is a common and reasonably easy way to widen timber. Glue would be inserted into the holes that house the dowel as well as the surrounding timber. An important note is that the dowel pieces do not fit perfectly in the holes that house them as there must be room for expansion.
|
Biscuit JointSimilar to the Dowel Joint the Biscuit Joint has the same purpose. This type of joint would be made through the use of a biscuit jointer - an electric hand held machine. The machine cuts out a hole in the timber not to similar to the biscuit shape, hence the name. Like the Dowel Joint it requires glue in the holes as well as the surround timber.
|
Tongue and Groove JointThe most common place to see a Tongue and Groove Joint is in timber flooring. It is treated like a locking mechanism to hold all of the pieces of timber together. Again like the Mortise and Tenon Joint this one has a rule. It is also 1/3 of the thickness of to be cut for the groove. Only glue is required to hold these together.
|
Rebate Widening JointThe Rebate Widening Joint is sometimes used to widen timber. It is not as strong and requires nails and glue to hold it together losing most of its aesthetic appeal.
|
Butt JointThe most common and easiest way to join two pieces of timber. Glue is the only requirement, however it is extremely important that the cuts of the timber are matched correctly. If both timbers bow the same
