This step-by-step guide is based on a woodworking technique demonstrated by Matt from Next Level Carpentry. It focuses on cleanly and accurately notching a wood post, a fundamental skill for building strong structures like decks, pergolas, and stair supports.
Mastering notching techniques helps ensure that components fit together tightly and securely. With careful marking, precise cuts, and proper cleanup, you can create notches that add both strength and visual appeal to your woodworking projects.

Why Notching Matters in Woodworking
Notching allows beams, joists, and posts to connect in a way that shares loads evenly. Rather than relying solely on screws or fasteners, a well-cut notch provides mechanical strength, which improves durability.
This technique also enhances the appearance of finished projects by creating clean, intentional joinery. Whether you’re working on a backyard pergola or a heavy-duty deck, clean notches make a noticeable difference in both performance and aesthetics.
Centering the Post
The first step is finding the exact center of the post. Using a framing square, you can mark midpoints along all faces, creating a reference grid that keeps your notch balanced and symmetrical.
Centering the post properly is critical because even slight misalignments can lead to visible flaws or weakened joints later. Taking time at this stage sets up the entire process for success.
Setting Up the Saw for Depth
Once the post is marked, the next step is adjusting your saw for the right depth of cut. Carefully setting the blade to match the desired notch depth ensures consistency across all your cuts.
The post should be held securely to prevent movement. Having a stable setup not only makes your work more accurate but also much safer.
Making the First Reference Cuts
Start by establishing your bottom reference line with an accurate cut. This line becomes the anchor for the rest of the notching work, ensuring that depth and alignment stay consistent.
After the bottom line is cut, a few shallow cuts are made toward each end of the notch. These initial passes help guide the saw and make the material easier to remove later.
Creating Shallow Relief Cuts
To break out the waste wood cleanly, a series of shallow relief cuts are made across the face of the post. The cuts are spaced closely together, especially near knots or wavy grain, where wood is harder to control.
Holding the saw flat against the post is key. Tilting the saw can create uneven cuts, leading to gaps or rough edges that need extra cleanup.
Clearing Out the Waste
With the relief cuts in place, wood chips can be knocked out using a hammer and a sturdy wood block. Placing the block against the lip of the notch and delivering firm taps removes material efficiently.
Different types of wood react differently during this phase. Straight-grained wood usually breaks away easily, while knotty or twisted grain might require more effort and patience.
Flattening the Surface with a Chisel
After most of the material is removed, a sharp chisel is used to clean and flatten the notch. Working with the flat side of the chisel against the surface ensures a smoother finish.
Careful chiseling at this stage results in tighter, stronger joints when beams or braces are added. It also gives a professional appearance to the finished structure.
Notching the Second Face
Once the first side is complete, the post is flipped to repeat the process on the opposite face. The same steps—marking, cutting, clearing, and chiseling—are followed for consistent results.
Extra cuts near knots or tough grain are again helpful to prevent tearing or splintering. Consistency between sides is important for keeping posts level and aligned when they are installed.
Tips for Success
Keeping your saw sharp and your work surface stable makes a big difference in how quickly and accurately you can notch. Clearing out sawdust between cuts also helps maintain visibility and precision.
It’s a good idea to practice on scrap wood before working on finished posts, especially if you’re new to notching. Building muscle memory and understanding grain behavior ahead of time reduces mistakes on critical pieces.
Mastering a Core Woodworking Skill
Notching wood posts cleanly and accurately is a skill that pays off across many types of builds. Whether you’re working on heavy outdoor structures or detailed framing indoors, having strong, well-cut notches improves both strength and appearance.
Matt’s method emphasizes careful planning, deliberate cuts, and patient cleanup. Following his process helps woodworkers of any level achieve professional-grade results without frustration.

Matt’s Take
These are my personal thoughts and tips based on my own experience in the shop. This section is not written, reviewed, or endorsed by the original creator of this project.
The beauty of a good notching technique is that it works across so many different projects. Whether you’re dealing with 4×4 posts for a pergola or smaller dimensional lumber for indoor work, the basic principles stay the same. The key is really in that initial setup — getting your measurements right and your saw depth dialed in perfectly before you make any cuts.
One thing I always emphasize in the shop is having sharp tools. A dull chisel will tear the grain instead of slicing through it cleanly, and you’ll end up doing way more work to get a smooth surface. Same goes for your saw blade — if it’s getting dull, you’ll notice more tear-out and rougher cuts that need extra cleanup time.
Safety-wise, keeping that workpiece rock solid is crucial. I see a lot of folks rush the clamping step, but a post that shifts mid-cut can bind your blade or throw off your measurements. Take the extra minute to secure everything properly, and you’ll work faster in the long run because your cuts will be more accurate.
The relief cut method shown here is really smart for waste removal. It’s much safer than trying to hog out big chunks in one pass, and you get better control over the final surface. Practice this technique on some scrap lumber first — once you get the rhythm down, you’ll be surprised how quickly you can knock out clean notches.
