OVERVIEW
Flat-frame construction joints are used to make things like mirror frames, window frames and door frames. Within these various frames, you will notice that pieces of wood are joined together using either corner joints, T-joints or crossover joints. By the end of this section on flat-frame joints, you should be able to name and recognise the various types of joints used within each frame and be able to suggest an appropriate joint for a given scenario.
The frames of stools, chairs and tables are made using flat-frame construction joints but each corner has two joints where the rails meet the leg at right angles to each other.
Wooden joints are used to create a bond between two or more pieces of timber. Most timber joints are permanent and are fixed together by wood glue or other fixings. There are many different types of wood joint and it is important that you pick the right one for the job. The joint chosen will depend on a number of factors, such as how strong the joint will have to be, whether the appearance of the joint is important, and how the pieces of wood meet, e.g. do you require a corner joint, T-joint or a crossover joint.
