Window closure system

Process

How it came together

  1. Step 01

    Redesign

    The castle already had its windows — our job was to design and build the closure systems that fit onto them. The original system was very labour-intensive to produce, so I redesigned the mechanism from scratch to speed up fabrication and improve reliability while matching the existing window geometry.

  2. Step 02

    SolidWorks & gear rack

    I drew the entire system in SolidWorks, including a custom gear rack with the right toothing so the mechanism moved exactly 34 mm per actuation. Every circular component was modelled to spec and sent to our laser cutting partner for precision cutting.

    Fabrication

    Laser-cut circular parts arrived ready to fit. The closure mechanisms were assembled and checked against the CAD, with the gear rack and moving components tested for the 34 mm stroke before installation.

    Installation

    All 17 closure systems were coded and shipped to the castle site, where installers fitted each unit onto its matching existing window.
