# Bridle joint

## What is a Bridle joint?

A bridle joint is best used in framing. It is often used in furniture framing to join rails to legs. A bridle joint is made up of 2 pieces, a mortise with an open-ended slot, and a tenon which has 2 protruding sides. Both pieces interlock with one another. To avoid coming apart, glue or pins are required to hold the joint together. Once assembled, a bridle joint can be shaped e.g. rounded, without affecting its strength.

There are various variations of bridle joints:

* **Corner bridle:** two end pieces joined to form a corner
* **Half mitred bridle:** two end pieces joined to form a corner, where one side is at a 45° angle
* **Mitred bridle:** two end pieces joined to form a corner, where both sides are at 45° angles
* **Tee bridle:** one end piece joined to the middle of another piece

Other than their appearances, the **main difference** between the corner bridle, the half-mitred bridle and the mitred bridle is the strength of the joint. The corner bridle joint is stronger due to its larger gluing surfaces.

## How do I make it?

The process to create a bridle joint will vary from project to project. To make this joint in the easiest way possible, you can use the [table saw](/machine-workshop/spaces/machine-workshop/equipment/untitled/table-saw.md) and tenoning jig available in the **MSD Machine Workshop**.

For more information, below is a video demonstrating making a bridle by hand.
