Comparison of Mortise Hinges
| Type of Mortise Hinge | Description | Applications | Advantages |
|---|---|---|---|
| Full-Mortise Hinge | Both leaves are mortised into the door and frame | Heavy doors, commercial applications | Flush appearance, smooth operation |
| Half-Mortise Hinge | One leaf is mortised into the frame, the other is mounted on the door | Lighter doors, cabinets | Easier installation, visible hinge design |
| Non-Mortise Hinge | Not recessed; mounted on the surface of the door/frame | Lightweight doors, interior applications | Simple installation, varied designs |
| Self-Closing Hinge | Automatically closes the door when released | Bathroom and kitchen cabinets | Convenience, enhanced privacy |
Types of Mortise Hinges
Full-Mortise Hinges
Full-mortise hinges are the standard choice for many applications where a professional finish is desired. Both leaves are sunk into the door and frame, making them flush. This design not only enhances the aesthetic appeal but also allows for a wider door swing. Installing full-mortise hinges requires precision and skill, making it essential to follow proper mortising techniques.
Half-Mortise Hinges
Half-mortise hinges consist of one leaf that is mortised into the door frame, while the other leaf is mounted on the door’s surface. This type is often used for lighter doors and cabinets. The visibility of one leaf can add a decorative element to the installation, making it a popular choice in residential applications.
Non-Mortise Hinges
Non-mortise hinges are ideal for lightweight doors where a simple surface-mounted installation is sufficient. These hinges do not require any cutting into the door or frame, making them easy to install. They come in various designs and finishes, offering versatility for different styles and preferences.
Self-Closing Hinges
Self-closing hinges are a functional variation that automatically closes the door once it has been opened. They are commonly used in kitchens and bathrooms where privacy is desired. The mechanism used in self-closing hinges can vary, but it generally involves tension springs that facilitate the closing action.
Installation Methods for Mortise Hinges
Tools and Preparation
Before starting the installation, ensure you have the necessary tools: a chisel, a router (for full mortise), a drill, screws, and a level. Proper measurements are essential to ensure a perfect fit. Check the door and frame alignment, marking the hinge locations carefully.
Mortising Techniques
- Chisel Method: This traditional technique involves using a chisel to carve out the mortise for the hinge. It’s best suited for those with a steady hand and experience.
- Router Method: Using a router and a jig allows for more precise and consistent mortises. This method is recommended for larger projects or when multiple hinges are involved.
- Template Method: Creating a shop-made template can help achieve uniform depth and width across multiple hinges, ensuring a professional finish.
