This project was built and designed by Michael from Maker At Play. It’s a custom table saw jig built to improve the precision and repeatability of miter cuts, especially for woodworking projects that rely on tight angles and clean corners.
By creating a dedicated miter sled, Michael simplifies the process of getting accurate results every time without constantly adjusting the saw blade. It’s a smart addition to any shop, especially for those who regularly work with frames, boxes, or angled joinery.

Why a Miter Sled Jig Matters
As projects grow more complex, setup time becomes a real concern. Using a standard miter gauge or freehand angles can quickly lead to small errors, especially when working with repeatable cuts or delicate materials.
Michael’s sled design aims to eliminate those inconsistencies. By holding the workpiece steady and aligning the cut at a fixed 45-degree angle, the jig produces results that are both accurate and efficient.
Materials and Basic Layout
The jig is built from strong, stable wood, chosen for its durability under repeated use. While specific measurements aren’t required for this overview, the key components include a flat base, two runners for the table saw’s miter slots, and side fences to guide the material during cuts.
Hardwoods or high-quality plywood are ideal for the base and fences. Stability is the goal, so avoiding soft or warped boards is important. Michael’s build focuses on quality materials without adding unnecessary complexity.
Cutting the Base and Runners
The build begins by cutting the base panel to size. This serves as the platform for all other components. Two runners are then milled to slide smoothly in the miter slots on the table saw.
Getting these runners snug but not too tight is essential. Too loose and the sled will wobble—too tight and it won’t slide freely. A few test fits and adjustments get it dialed in.
Setting Up the Side Fences
To create precise miter cuts, the side fences are set at 45 degrees. Michael uses a square to ensure alignment, clamping each fence in place before attaching it to the base.
Accuracy here is crucial. If either fence is even slightly off, it will affect every cut made with the sled. Double-checking angles and alignment before securing the parts helps guarantee the best results.
Lightening the Sled with CNC Trimming
After assembling the base and fences, Michael trims excess material using a CNC machine. This reduces the sled’s overall weight, making it easier to handle without affecting its structural integrity.
While this step isn’t required, it’s a useful technique if you have access to a CNC. Removing non-essential material gives the sled a cleaner look and makes it more practical for regular use.
Planning for Clamping
One smart addition Michael considers is leaving space for clamps or adding clamp slots. While his original version works well, he notes that adding more clamping points would improve the sled’s ability to handle small or narrow pieces.
If you’re building a similar jig, consider marking potential clamp locations during the design phase. This foresight can make the sled more versatile in the long run.
Initial Testing and Adjustments
Once assembled, the jig is tested with a few sample cuts. Minor gaps in the resulting miter joints reveal areas that need fine-tuning. This might include adjusting the fence angle or sanding down a slightly misaligned runner.
Michael demonstrates that even small tweaks can make a big difference. Taking time to refine the jig ensures reliable performance on future projects.
Adding Grip with Sandpaper
To prevent material from slipping during cuts, Michael recommends adding a strip of sandpaper to the surface of the fence or base. This creates just enough friction to keep boards in place without clamping.
It’s a small detail that improves safety and accuracy, especially when cutting smaller workpieces or working without a stop block.
Advantages of Using a Miter Sled
The biggest advantage of a miter sled is the time it saves. Once it’s built and calibrated, you can make accurate, repeatable cuts without fussing with blade angles or awkward setups.
The sled also adds a level of safety and control, allowing you to secure workpieces and avoid binding during cuts. It’s a great upgrade for anyone who frequently makes mitered frames, corners, or trim pieces.
A Practical Shop Upgrade
This miter sled project is a great example of how a simple jig can improve woodworking results across the board. It doesn’t require fancy materials or complex tools—just attention to detail and a focus on clean execution.
Michael’s version is easy to adapt to your own table saw, and once built, it’ll quickly become one of your go-to shop tools.
