When installing a door, one of the essential steps is cutting mortises for the door hinges. Many people rely on a router for this job, but if you don’t have one or prefer a more hands-on approach, it’s absolutely possible to achieve professional results using traditional hand tools. In this guide, we’ll walk you through the entire process of cutting door hinges without a router, from preparing your tools to securing the hinges in place.
Introduction
Cutting door hinges without a router might seem tricky, but trust me, it’s totally doable with the right techniques and tools! You just need some hand tools like chisels, hammers, and utility knives to get rolling. In this article, I’ll walk you through the step-by-step process to make cutting hinge mortises a breeze—even if you’re not using power tools!
Why Avoid Using a Router?
Many woodworkers and DIY enthusiasts opt to avoid using a router for various reasons:
- Cost Efficiency: Routers and router bits can be expensive, particularly for those who only need them for small projects.
- Lack of Equipment: Not everyone has access to a router, and buying one for a single task may seem unnecessary.
- Preference for Hand Tools: Some people simply prefer the control and satisfaction that comes with working by hand, especially for detailed jobs like hinge mortises.
Tools Required for Cutting Door Hinges Manually
Before starting, gather these essential tools:
- Hammer: For tapping the chisel into the wood.
- Chisel: A sharp chisel (typically 1/4″ to 1/2″ wide) to carve out the mortise.
- Utility Knife: To score the outline of the hinge.
- Measuring Tape or Ruler: For accurate hinge placement.
- Pencil or Marker: To mark the hinge locations.
Optional tools include sandpaper or a small file to smooth out any rough areas.
Choosing the Right Door Hinges

Before you start cutting, it’s important to select the right hinges for your door. Hinges come in various sizes and types, so you’ll want to choose ones that match your door and frame specifications.
- Types of Hinges: Butt hinges are the most common for interior doors, but there are also continuous hinges, flush hinges, and pivot hinges for different needs.
- Hinge Size: Ensure the hinge size matches the thickness and weight of the door. Standard interior doors typically use 3 1/2″ or 4″ butt hinges.
Preparing the Door for Hinge Installation Before cutting the mortise, you need to measure and mark where the hinges will be placed.
- Marking the Hinge Locations: With the door in place (or positioned on sawhorses), use a measuring tape to mark the top and bottom hinge locations. The top hinge is generally positioned 5–7 inches from the top of the door, and the bottom hinge is around 10 inches from the bottom.
- Using a Template: Some hinges come with templates. You can use these for a more accurate outline.
Marking the Hinge Outline on the Door Once the hinge locations are marked, trace the outline of each hinge on the edge of the door using a pencil or utility knife.
- Freehand or Template: Use a hinge as a guide, or employ a template for a perfect outline.
- Scoring with the Knife: Using a utility knife, carefully score along the lines you’ve marked. This ensures clean edges and prevents the wood from splintering as you chisel.
Scoring the Outline with a Utility Knife Scoring the outline with a utility knife is a crucial step in creating a crisp edge for the hinge mortise.
- Precision: Cut lightly at first, then deepen the score with each pass. The depth should be just enough to guide your chisel later.
- Avoiding Mistakes: Take your time to avoid cutting too deep or outside the marked lines.
Creating Depth for the Hinge After scoring, it’s time to create the necessary depth for the hinge to sit flush against the door.
- Depth of the Mortise: The typical depth is equal to the thickness of the hinge leaf. Measure the thickness of the hinge and mark that depth on the door edge.
- Chiseling Step-by-Step: Hold the chisel at a 90-degree angle to the door, and tap it with a hammer to remove small amounts of wood inside the scored outline.
Cutting Along the Outline with a Chisel Carefully use the chisel to cut along the scored outline.
- Clean Cuts: Work slowly and precisely, using a sharp chisel to ensure smooth, even cuts. Cut away small amounts of wood at a time.
- Working with Grain: Be mindful of the wood grain to avoid splintering, especially if the door is made from softer wood.
Removing Excess Wood for the Hinge Mortise Once you’ve cut around the perimeter, it’s time to remove the wood within the hinge outline.
- Proper Technique: Use the bevel side of the chisel facing down to remove layers of wood. Work in stages until the mortise reaches the desired depth.
- Avoiding Splits: Take care not to remove too much wood at once, which can cause splintering.
Fine-Tuning the Mortise After removing the bulk of the wood, you may need to refine the mortise.
- Smoothing the Edges: Use the chisel or sandpaper to smooth out any rough edges.
- Ensuring a Perfect Fit: Test the hinge to ensure it sits perfectly within the mortise. If it’s too tight, remove a little more wood; if it’s too loose, you’ll need to fill gaps or tighten screws carefully.
Test-Fitting the Hinges Once the mortise is complete, test-fit the hinges to check for proper alignment.
- Checking for Fit: The hinge should sit flush with the edge of the door. If it sticks out or wiggles, you may need to adjust the mortise.
- Adjustments: Use the chisel to remove or add wood where necessary until the hinge fits perfectly.
Securing the Hinges to the Door With the hinges fitting properly, it’s time to secure them.
- Drilling Pilot Holes: Use a drill to create pilot holes for the screws. This prevents the wood from splitting and makes screwing in the hinges easier.
- Fastening the Hinges: Screw the hinges firmly in place, ensuring they’re aligned and flush with the mortise.
Installing the Door Now that the hinges are attached to the door, it’s time to install it onto the frame.
- Attaching the Hinges to the Frame: Align the door in the frame and secure the other side of the hinges to the door jamb, making sure everything is level and moves smoothly.
Common Mistakes and How to Avoid Them Some common mistakes include:
- Misaligned Hinges: Ensure precise measurements before cutting.
- Uneven Mortises: Take your time chiseling and use a sharp chisel to avoid rough cuts.
Alternatives to Using a Router While a router is a common tool for hinge mortising, other tools can achieve similar results.
- Dremel: A Dremel with the right attachment can also cut hinge mortises.
- Hand Planes: Can be used for minor adjustments and smoothing.
Safety Tips for Cutting Door Hinges Manually
Safety is key when working with sharp tools.
- Wear Gloves: To protect your hands from slips.
- Keep Tools Sharp: Dull tools are more dangerous than sharp ones.
- Use Eye Protection: When working with wood and tools, wear safety glasses.
Maintaining Your Hand Tools
To ensure clean cuts and long-lasting tools, regular maintenance is necessary.
- Sharpening Chisels: Use a sharpening stone to keep your chisels in top shape.
- Cleaning and Oiling: Clean your tools after use and oil metal parts to prevent rust.
