Un disco graduato serve per misurare angoli o come adesivo circolare (es. tachimetro, decal). Questa guida presume che desideri un disco circolare con tacche e numeri da stampare in scala reale per Vespa (dimensione tipica: 110–140 mm di diametro). Userò 120 mm come default.

Se cerchi quel tocco in più o non hai una stampante:

Consiglio Pro: Se devi regolare spesso Vespe diverse (es. una 50 Special e una PX 125), stampa due dischi: uno piccolo per i volani stretti e uno grande per i volani larghi. Maggiore è il diametro del disco, più facile sarà leggere l'esattezza del grado.

Finding a reliable disco graduato (timing degree wheel) is a rite of passage for any Vespa enthusiast looking to tune their engine, set ignition timing, or check port timings.

Here is a detailed guide on how to find, print, and use a timing wheel for your project. Disco Graduato Vespa: The Ultimate DIY Guide

Whether you are running a classic PX, a smallframe Special, or a tuned PK, precision is everything. Setting your ignition timing (anticipo) correctly can be the difference between a smooth-running machine and a hole in your piston. 1. Why You Need a Degree Wheel

Most Vespa stator plates have alignment marks, but they are notoriously inaccurate—especially if you’ve swapped to an aftermarket ignition like Vespatronic or Pinasco. A 360° degree wheel allows you to: Find Top Dead Centre (TDC) with mathematical precision. Measure exactly where your spark fires. Calculate cylinder port timings (Transfer and Exhaust). 2. Where to Download the PDF

You don't need to buy a metal one. A paper version glued to a stiff piece of cardboard or a scrap piece of sheet metal works perfectly. Recommended Downloads:

SIP Scootershop: Often provides free printable templates in their tech manuals. disco graduato vespa da stampare pdf

Vespa Resources / VR Forum: Search for "Disco Graduato PDF" in the "Download" sections of major Italian Vespa forums.

DIY Option: Any standard 360-degree protractor image works, provided it is high-resolution. 3. How to Print for Accuracy

The most common mistake is printing the wheel at the wrong scale. Open your PDF.

In the print settings, select "Actual Size" or "Scale: 100%".

Do not select "Fit to page," as this will distort the measurements. Print on Cardstock (200gsm+) if possible. 4. Setting It Up on Your Vespa Once printed and cut out, follow these steps:

Mounting: Use the flywheel nut to secure the disc to the flywheel. Alternatively, many mechanics use a magnetic base or a simple bolt through the center of the disc into the crankshaft.

The Pointer: Create a "pointer" using a stiff piece of wire (like a coat hanger) attached to one of the engine case bolts. Point it directly at the outer edge of your disc.

Find TDC: Use a piston stopper tool. Turn the flywheel clockwise until it hits the stop—note the degree. Turn it counter-clockwise until it hits the stop—note that degree. The exact midpoint between these two numbers is your True Top Dead Centre (0°). 5. Pro Tips for Success

Laminate it: A single drop of oil or petrol will ruin a paper disc. Apply clear packing tape over the face before cutting it out to make it "workshop-proof."

Check the Diameter: Ensure the disc is large enough to be read easily (at least 15cm–20cm) but small enough that it doesn't hit the floor or the frame while the engine is in the chassis.

Searching for a "disco graduato Vespa da stampare PDF" (Vespa timing degree wheel to print) is the standard DIY approach for accurately setting ignition timing or measuring cylinder phases. These printable discs are essential for determining the Top Dead Center (TDC) Il mercato è pieno di dischi graduati in

and the exact firing point (expressed in degrees before TDC). Reliable PDF Resources Scooter Help Timing Disc

: A highly recommended resource that includes a clear goniometer and a built-in reference table for common Vespa models (e.g., PX, Special, Rally). Virtual Italia Disco Graduato

: A clean, large-scale PDF often cited in Italian forums like Vespa Club Mugello Blocklayer Degree Wheel Generator

: Allows you to customize the size and text of the wheel before printing, which is useful if you want to glue it to a specific object like a CD for extra rigidity. s750474d8371b5690.jimcontent.com Practical Tips for Use

: Print the PDF on thick paper or cardstock. For the best stability, glue the cutout disc onto an old CD or a thin piece of plexiglass.

: Use a simple magnet over the central circle to attach the disc directly to the flywheel. Finding TDC : You will need a piston stopper

(bloccapistone). Rotate the flywheel in both directions until it stops; the exact midpoint between those two readings on the disc is your true Top Dead Center.

: Use a piece of stiff wire (like a coat hanger) attached to a crankcase screw as a fixed indicator for reading the degrees. Common Timing References (BTDC) Misurazione fasi cilindro - Vespe tutorial

Ignition timing is measured in degrees Before Top Dead Center (BTDC). Common factory settings include: Vespa 50/90 : 19° BTDC Vespa Primavera (VMA2) : 24° BTDC Vespa PX 125/150: 21° - 22° BTDC Vespa Rally 180 : 22° BTDC Vespa 180 SS : 26° BTDC How to Use the Degree Wheel

To accurately set your timing, you must first find the Top Dead Center (TDC), which is the highest point of the piston's travel. DISCO graduato.pdf
