Modeltruck Peterbilt and Scania with Dad and Son

The inspiration for this model came from a video of a Dutchman driving through a parking lot that was unintentionally discovered on the Internet. I started out eagerly to collect drawings and sketches of the outstanding American truck, the Peterbilt 359. I needed to make a correctly proportioned wood frame that I utilized to create the resin counterform, 

I received the final cabinet built of light and sturdy fiberglass thanks to the release agent and a lot of patience, and after a few hours of meticulous sanding and polishing, I got the final product. The frame, which is made up of two iron pipes 60x30mm and 1.5mm thick, is strong and can withstand heavy weights and bending due to its unique structure, which is linked to the main frame by four springs and two strong iron nails. It is powered by 750 watts at 36 volts, and motion is transmitted to the twin wheels via wheels and a pinion chain transmission.

I was inspired by the steering mechanism used in go-karts, where the two wheels have a distinct turning radius inside and outside the bend you're creating. All of this is powered by a 12v motor obtained from an electric jack with a high torsional force.

To have a genuine truck, you need the correct horn, so I installed a 12v twin-cylinder small compressor under the model's hood that can produce up to 10 bar of pressure. I use two solenoid valves to regulate two types of horns: two above the cab on a smaller scale, and two at the bottom of the life-size frame. To make the model more realistic, I added a smoke machine similar to those found in discos. After a lengthy search, I was able to locate one in a smaller size that would allow me to attach it to the bottom of the frame.

I still have the problem of keeping it operating since it requires 220v, therefore I have to install an inverter that generates 220v from 12v. Because chrome distinguishes American vehicles, I should outfit my model with as many chrome components as feasible. The most crucial are the tanks I created from normal construction plastic pipes, the ends of which are closed with wood/putty for bodybuilding and sanded for hours before being transformed into genuine tanks. In the same technique, I made the air filters that hang on the cabinet's sides.

It took me hours of sleep to build this model over a nine-month period, but every time I see it following me as I walk or carry me, I feel indescribable joy; the joy is amplified because I was also the first to make such a model in Italy.
