Cessna 152 Aircraft Clock - 2-1/4" Standard Flight Sim Gauge

Designed completely from scratch using the metric system, it scales down the original dimensions while maintaining perfect aesthetic and mechanical compatibility with standard simulator panels.

📐 Mechanical Specifications & Standards

• Interface Standard: Based on the universal MS33638 / SAE AS415 aviation standard for 2-1/4" (57.15 mm) cockpit instruments.

• Mounting Configuration: Authentic 2-hole diagonal mount (Top-Left / Bottom-Right) matching the real Cessna 152 layout.

• Bolt Circle Diameter (BCD): 66.5 mm interaxis (oriented at 45° from the center, X/Y offset: ±23.5 mm).

• Bezel Size: 60.5 mm square (covers a standard 57.5 mm panel cutout).

🛠 Hardware Requirements

To complete this build, you will need:

• Glass/Lens: 1x standard circular glass or acrylic disc with a 50 mm diameter, 2 mm thickness.

• Movement: 1x standard mini quartz wall clock mechanism (56x56 mm body size).

• Q.ty 2 M3 heat-set inserts, 1 white 3mm LED

• Mounting Screws: Designed to be adapted with standard metric M3 screws.

The assembly is optimized for a "rear-mount" approach: the square 56x56mm quartz mechanism sits comfortably and hidden behind the simulator panel, while only the circular gauge bezel slides into the 57.5mm panel hole from the back. No complex modification or "squaring" of the panel cutout is required.

• Dial & Hands: The dial face is a custom JPG file printed on paper and laminated for durability. The seconds hand from the quartz mechanism kit must be modified/trimmed to fit inside the 46mm housing.
