This project was built and designed by Stan Sullivan. It’s a fast and practical solution for making accurate hand-sawn cuts using only scrap wood and a few basic tools.
While miter saws dominate modern workshops, the classic miter box still holds value—especially in quieter, more controlled settings or when power tools aren’t available. Stan’s build offers a custom-sized, reliable guide that can be made quickly and tailored to any project.

Why Build a Miter Box?
Miter boxes are simple jigs used to guide hand saws for clean, consistent angled cuts—most often at 45 and 90 degrees. While they’ve been around for generations, their usefulness hasn’t faded.
Stan highlights that building your own miter box gives you full control over its size and angles. Whether you’re trimming picture frames, cutting small molding pieces, or working without electricity, a custom miter box is a great tool to have on hand.
Selecting the Materials
The build starts with scrap wood, making it both eco-friendly and cost-effective. Stan suggests using durable hardwoods like oak or maple for longevity, but pine or other softwoods will also do the trick if that’s what you have on hand.
The key is to use wood that’s flat and solid enough to hold up to repeated sawing. Since this is a shop tool that may see regular use, sturdiness is more important than appearance.
Laying Out the Sides
Two pieces of wood are selected to form the sides of the box. These pieces should be tall enough to support the workpiece and long enough to give your saw a solid guiding surface during each cut.
Stan walks through the steps of trimming the pieces down to equal length. He suggests using a miter saw if available, but a circular saw or even a hand saw will work with care.
Optional Joinery Enhancements
To secure the sides to a base, Stan uses a router to cut dado grooves along the bottom edge. These dados help align the base perfectly and provide extra glue surface.
If you don’t have a router, pocket holes or simple butt joints are alternatives. The goal is to keep everything square and flush so that your saw remains guided during every cut.
Marking and Cutting the Angles
Once the sides are attached, the next step is to mark the cutting slots. Stan recommends using a combination square to scribe exact 45-degree angles on both sides of the box.
Accuracy here is crucial. Once marked, Stan uses a fine saw to carefully follow the lines, letting the weight of the saw do most of the work. This technique keeps the cuts smooth and aligned across both walls of the miter box.
Creating the Saw Guides
After the angles are established, Stan cleans up the saw paths using a chisel. He carefully removes material along the knife wall to create a clean and accurate guide channel.
The purpose of these channels is to ensure repeatable cuts. As the saw runs along these guides, it stays locked into the correct angle without drifting—a must for consistent results.
Final Assembly and Finishing Touches
After the guide slots are cut, the miter box is glued together and clamped while drying. Stan checks for square at every step, making sure the box stays aligned through the glue-up.
Once dry, any rough edges are sanded smooth. There’s no need to apply finish unless desired—the tool is now ready for use.
Why Every Woodworker Should Have One
Stan points out several benefits to using a miter box. For one, it’s quieter and safer than using a powered miter saw, which is ideal in shared spaces or when working early or late in the day.
It’s also a great way to practice hand-sawing skills and build muscle memory. Beginners can gain better control, while seasoned woodworkers can use it for fast, precision cuts without setting up power tools.
Useful in Emergency Situations
Beyond the workshop, miter boxes shine in scenarios where power tools are unavailable—like power outages or remote locations. Stan notes that after a hurricane, his miter box allowed him to keep working when electricity wasn’t an option.
This practicality makes it a worthwhile backup tool for any woodworking setup.
A Simple, Fast, and Rewarding Shop Project
This quick build shows that not every useful shop tool has to be expensive or time-consuming to make. With 15 minutes, some scrap wood, and a bit of focus, you can create a long-lasting addition to your toolkit.
Stan’s straightforward method highlights how small projects can still make a big impact in the shop. It’s an excellent reminder that sometimes the old tools are still the best tools—especially when you make them yourself.
