How To Make Finger Joints With A Table Saw
If you are looking to add a decorative touch to your woodworking projects, finger joints are a great option. Finger joints, also known as box joints, are a series of interlocking cuts that create a strong and visually appealing joint. With the help of a table saw and a few simple steps, you can easily make finger joints that will enhance the quality and beauty of your woodworking projects.
Before you get started, it is important to gather the necessary tools and materials. You will need a table saw with a dado blade set, a miter gauge, push sticks, and a piece of wood that you will be creating the finger joints on. It is also helpful to have clamps and a measuring tape on hand to ensure accuracy throughout the process.
To begin making your finger joints, set up your table saw with the dado blade set at the desired width of the fingers. The width will depend on the thickness of the wood you are using and the size of the joints you want to create. Once the dado blade is set, position the miter gauge to make perpendicular cuts on the ends of your wood piece.
