How To Make a Box Joint Jig For The Table Saw? – Complete Guide

Making a box joint jig is a great way to cut joints in wood without having to spend hours sanding and finishing them. The jig also makes it easier to cut multiple pieces at once.

A box joint jig consists of two parts: a base and a guide. The base holds the wood securely in place, and the guide guides the blade along the edge of the board. 

Box joints are very important in woodworking because they allow you to create perfectly aligned cuts. 

How To Make a Box Joint Jig For The Table Saw

If you’re looking for a simple and inexpensive method to cut joints in wood, then I’d recommend making a box joint jig.

I’ve used this technique many times over the years and it works great every single time.

  1. Cut the Plywood

    Start by cutting the plywood into four equal pieces. Each piece should measure approximately 6 inches x 12 inches.

  2. Make the Joint Boxes

    Next, remove the center section of each 2×4. This is where the joint boxes will go.Use a drill press to create pilot holes in the ends of the boards. Use a 3/8 inch bit to do this.Drill three evenly spaced holes along each edge of the board. You’ll use these holes later to attach the box joints to the board.Attach the boards together using screws.

  3. Attach the Box Joints

    Now it’s time to add the joint boxes. Now it’s time to add the joint boxes. Place the boards on top of each other as shown. Measure and mark the location of the center hole on the bottom of the first board. Repeat this step for the second board. Use a jigsaw to cut out the hole. Cut the remaining two sides of the box. Sand the edges smoothly.

  4. Assemble the Box Joints

    The final step is to assemble the box joints. First, place the boards back onto the base with the joint faces up. Then, align the boards so that all the holes line up.Clamp the boards together.Apply glue to the inside face of one of the boards. Press the joint firmly against the base. Allow the glue to dry completely before moving the assembly.

  5. Final Assembly

    Finally, reassemble the box joints on the base.You can now clamp the assembly down to your work surface.Make sure to apply enough pressure to ensure that the boards stay flat during the cutting process.This box joint jig works well for any type of joint. It’s easy to build and requires little effort to operate.

Tips for safety

Joint boxes are used to store nails and screws. They come in different sizes and shapes.They are usually made out of wood, plastic, metal, or cardboard.If you don’t use them properly, they can cause serious injuries.Here are some tips for the safe handling of these boxes.

1. Use a hammer instead of a screwdriver.

A hammer is safer than a screwdriver.Using a hammer makes sure you hit the nail head first. This helps prevent injury.

2. Make sure the nail is completely driven into the wood.

When using a hammer, make sure the nail is fully embedded into the wood.This prevents the nail from popping out later.

3. Don’t cut too deep.

Cutting deeper than necessary can damage the wood.

4. Avoid hitting yourself.

Always wear eye protection while working with tools.Use goggles or safety glasses.Make sure you’re wearing gloves.Wear earplugs.

5. Be careful when lifting heavy objects.

Be aware of your surroundings and avoid lifting heavy objects.

6. Keep away from open flames.

Never leave a burning tool unattended.

7. Always be careful when moving the toolbox.

Keep the toolbox close to where you are working.

8. Never place the toolbox on an unstable surface.

Place the toolbox on a stable surface like concrete or a table.

9. Clean up after yourself.

Clean up your workspace after each project.

10. Keep track of loose nails and screws.

Store nails and screws in their original containers.

11. Store the toolbox somewhere safe.

Don’t keep the toolbox near an area where kids play.


How Do I Cut a Butt Joint?

A butt joint is created by joining two pieces of stock together at a 90- degree angle. To create a perfect butt joint, follow these steps:

1: mark the center point of the board using a pencil.
2: use a straightedge to draw a line across the middle of the board.
3: measure down 3/16 inches from the centerline.


Most people think that cutting joints for woodworking projects is difficult and dangerous. But, this is not true. In fact, there are many different ways to cut joints safely and efficiently.

There are two main types of joints used in woodworking. One type is called a “butt joint”. This type of joint is made up of two pieces of material joined together at a 90-degree angle. Another type of joint is called a “miter joint”. A miter joint is created by making a 45-degree angle at one corner of a piece of material.

Both butt and miter joints are commonly used in furniture construction. They are used to make tables, chairs, shelves, etc.

But, there are many different methods to create these joints. Some of the most popular methods include using a jigsaw, circular saw, band saw, router, and a combination of these tools.

Jigsaws are great for creating butt joints. Circular saws are great for creating miter joints. Band saws are great for cutting angles. Routers are great for cutting curves. And, a combination of these tools can be used to create almost any kind of joint.

So, don’t let the thought of cutting joints scare you away from doing woodwork. There are many safe and effective ways to do so. You just need to find the right tool for the job.
