If your chamfers keep running too far, looking uneven, or you’re struggling to control your chisel, this step-by-step guide will help. In this lesson, you’ll learn how to cut a stop chamfer — a simple but important decorative cut that stops short of the ends of the timber.
This is a great beginner exercise to improve your marking out, chisel control, and accuracy.
🎯 Aim of the Lesson
To learn how to mark out and cut a stop chamfer accurately using hand tools, while maintaining clean lines and crisp corners.

🪚 Step-by-Step: How to Cut a Stop Chamfer
Step 1: Understand the Purpose of a Stop Chamfer
A stop chamfer is a bevel that does not run the full length of the timber. It starts and stops at set points, often used on staircase spindles and decorative joinery.
Step 2: Measure and Mark the Length
Decide where your chamfer will begin and end. In this example, the chamfer is 120mm long.
Mark both ends clearly across the timber.
Step 3: Mark Parallel Lines
Draw a line along the length of the timber between your marks, both on the face and the edge. These lines define the chamfer area.
Step 4: Set Your Angle (45°)
Using a combination square, mark a 45-degree line at both ends of the chamfer. This creates the angled “stop” points.
This step can feel tricky at first, but it gets easier with practice.
Step 5: Set the Chamfer Depth
Set your combination square to your desired depth (in this example, around 8mm).
Mark this measurement carefully from the correct reference face — avoid guessing from the outside edge.
Step 6: Mark the Waste Area
Lightly shade or mark the section you’ll be removing. This helps avoid cutting the wrong area.
Step 7: Secure the Timber
Clamp the timber firmly to your workbench. Keeping it stable improves accuracy and safety.
Step 8: Start Cutting Away from the Line
Begin removing material slightly inside the waste area, not directly on your lines.
Use controlled chisel movements and work gradually toward your marked lines.
Step 9: Work in One Direction First
Cut in one direction along the chamfer, then turn the timber around and work from the opposite direction.
This helps maintain control and reduces the risk of tearing the grain.
Step 10: Create Stop Cuts to Prevent Splitting
At each end, make a stop cut to prevent the timber from splitting beyond your lines.
This is key to achieving a clean stop chamfer.
Step 11: Refine the Shape
Continue removing small amounts of material, keeping the chamfer flat and even.
Avoid creating curves — aim for a clean, flat surface with sharp edges.
Step 12: Clean Up to the Lines
Once the bulk of the waste is removed, carefully trim back to your lines.
Take light cuts and focus on achieving crisp corners at each end.
Step 13: Check Your Work
Inspect the chamfer:
- Is it straight and even?
- Are the stop points clean and sharp?
- Does it match your markings?
Make small adjustments if needed.
⚠️ Common Mistakes to Avoid
- Cutting directly on the line too early
- Forgetting to make stop cuts
- Letting the chisel slip or dig in
- Rushing the process
- Creating a curved instead of flat chamfer
- Not securing the timber properly
✅ Key Tip
Take your time and focus on control. A stop chamfer is less about speed and more about precision — especially at the start and end points.
