Una volta che hai il tuo disco graduato stampato, ecco l’uso pratico:
A typical Vespa degree disc is a circle of 100mm to 150mm in diameter, printed with a full 360° scale in 1° or 5° increments. It features a central hole precisely sized to fit the Vespa’s flywheel side crankshaft stub (usually 10mm or 12mm diameter, depending on the engine type). Additional markings may include TDC (0°) and often a pointer arrow for reference. When the disc is mounted concentrically on the crankshaft and a fixed pointer is attached to the engine casing, the mechanic can rotate the engine slowly and read the exact angular position of the crankshaft.
The printable PDF version adds two crucial features: scalability and accuracy. A well-designed PDF is drawn in vector format, ensuring that when printed at 100% scale, the degree markings are metrologically consistent. Some templates even include multiple central holes for different Vespa models or a cut-out slot to clear the woodruff key. disco graduato vespa da stampare pdf
A printable graduated disc (PDF) is a low-cost, essential workshop tool for any Vespa restoration or tune-up. By following the printing instructions above and using the disc with a fixed pointer, you can achieve professional-grade timing accuracy.
