When

To make a joint that will be more attractive and sturdy than simply superimposing and screwing the two parts. Since the parts’ surfaces are flush, it is also possible to cover them with panels.

The tools

To make this joint, you will need a back saw, a wood chisel, a mallet, a square and a pencil.

How

This type of joint is simple and quick to prepare and make. In this example, a vertical part A is secured to a horizontal part B, to form a + pattern.

1. Place the parts in position

Place the parts in their desired position, i.e., superimposed where they will be joined.

2. Trace the lines

Using a pencil, carry over the width of one part to the other.
