What are piano hinges?

Piano hinges are continuous hinges used in various industrial applications. They are long, narrow, and provide a seamless connection between two parts. Being a crucial element in industries like automotive and aerospace, understanding their structure and function is essential.

How to cut piano hinges?

  • Measuring and Marking:

    • Measure: Determine the length of the piano hinge needed for your particular application.
    • Mark: Use a straightedge and a fine-pointed marker to mark the precise location where the hinge will be cut. The cut should be made in the gap between the knuckles, not through them.
  • Clamping:

    • Secure the Hinge: Place the hinge on a sturdy work surface, like a workbench, and use clamps to hold it firmly in place. This ensures stability and accuracy while cutting.
  • Choosing the Right Tools:

    • Hacksaw: A hacksaw with a fine-toothed blade designed for cutting metal can be used.
    • Power Saw with Metal Cutting Blade: If available, a power saw equipped with a metal cutting blade offers faster and more efficient cutting.
  • Cutting:

    • Align the Blade: Ensure the blade is aligned with the marked line.
    • Apply Even Pressure: Begin cutting, applying steady and even pressure. Let the blade do the work, rather than forcing it through the metal.
    • Check Alignment: Periodically check alignment to ensure you are following the marked line.
  • Finishing:

    • File the Edges: Once the cut is complete, use a metal file to smooth any rough or sharp edges. This provides a professional finish and ensures the cut edge is safe to handle.
    • Check for Alignment: Test the cut hinge in its intended application to ensure it fits properly.
  • Safety Considerations:

    • Wear safety glasses to protect your eyes from metal shavings.
    • Use gloves to protect your hands from sharp edges.
    • Follow the safety guidelines provided with the tools you are using.
