This project was built and demonstrated by Matt from Next Level Carpentry. It’s a smart, straightforward method for creating strong, professional-quality shelving using a custom jig for routing stopped dados.
Matt’s technique focuses on achieving clean, flush fits while making the routing process faster and more accurate. It’s a practical skill that can take your cabinet and shelving projects to the next level.

What Are Stopped Dados?
Stopped dados are grooves cut into a panel that stop before reaching the edge, leaving the exterior clean and unbroken. They’re ideal for shelves because they combine strength with a polished, professional appearance.
Unlike through-dados, which run from edge to edge, stopped dados keep the outside face of the cabinet or side panel intact. This small detail makes a big difference in how the final project looks and holds together.
Building the Routing Jig
The process starts by building a simple but highly effective jig. Matt uses melamine-faced particle board to create a smooth, durable guide for the router.
The jig consists of two parallel fences spaced precisely to match the router’s baseplate. This setup keeps the router centered and ensures each dado is the right width without complex adjustments.
Assembling the Jig for Accuracy
Assembly of the jig demands careful alignment to maintain square corners and parallel fences. A framing square is used to check each joint, and fasteners are combined with CA glue for instant adhesion and long-term hold.
Once assembled, the jig can be easily adjusted for different project dimensions. This flexibility makes it a reusable tool, saving time on future builds without sacrificing precision.
Laying Out Shelf Positions
Before cutting, it’s important to mark out where each shelf will sit. Matt measures and marks the inside of the side panels, setting consistent heights for each shelf location.
Careful layout ensures the shelves will be spaced evenly and fit properly within the cabinet. Small errors during this step could cause misalignment, so Matt stresses the importance of double-checking measurements before cutting.
Routing the Stopped Dados
With the jig clamped in place, the router is guided along the jig to cut a stopped dado at each marked location. The design of the jig makes it easy to produce consistent, clean channels without overcutting or drifting.
The bearing on the router bit follows the jig edges closely, meaning less chance for mistakes. Stopping the router at the right spot leaves a clean endpoint and preserves the outer faces of the cabinet.
Cutting Clean and Precise Dados
Matt demonstrates how to control the router carefully to get smooth, even cuts. The resulting dados are crisp and consistent, which helps the shelves fit tightly without gaps.
Because the jig eliminates much of the guesswork, even woodworkers newer to routing can achieve professional-looking results. It’s a repeatable method that improves accuracy on every project.
Notching the Shelves for a Perfect Fit
After cutting the dados, the shelves themselves need to be notched to fit into the stopped grooves. This simple step involves removing small sections from the back edges of the shelves.
Notching allows the shelves to slide into place while staying flush with the cabinet sides. It also reinforces the connection, improving the overall stability of the unit.
Testing the Fit
With the shelves cut and notched, Matt dry-fits everything together before final assembly. A snug fit is important because it keeps the shelves from shifting or sagging under load.
If necessary, minor sanding or trimming can fine-tune the fit without compromising strength. Taking the time to test fit ensures a smooth final build with fewer surprises later.
Securing the Shelves
Once the fit is confirmed, screws are used to fasten the shelves into the dados from outside the cabinet. Matt spaces the screws strategically to maximize support while keeping the fasteners discreet.
Countersinking the screws slightly helps hide them beneath plugs or filler later if a cleaner look is desired. Securing the shelves also prevents future racking or movement.
Stress Testing the Shelves
Before calling the project finished, Matt performs a quick stress test by applying downward pressure on each shelf. This step confirms that the dado joints are solid and capable of handling weight.
Any issues can be corrected now, before final sanding and finishing. It’s a good habit that saves time and prevents future problems with heavy loads.
Final Assembly and Finishing Touches
After the shelves are installed, Matt sands all surfaces to remove rough edges and prepare for finishing. Attention to detail here makes the finished project look clean and professional.
Depending on the project’s use, a protective finish such as varnish or polyurethane is applied. This step enhances the appearance of the wood and protects against wear and moisture.
Why a Stopped Dado Jig Is Worth It
This simple jig pays off by making shelving projects faster, stronger, and better looking. Instead of worrying about uneven joints or through-cuts, woodworkers can focus on precision and fit.
Matt’s method is proof that sometimes the best shop upgrades aren’t complicated—they’re smart, simple, and designed to make repeatable success easy.
