There are pieces of the motorbike which in my opinion are timeless iconic, like this 1950s (two-stroke single cylinder) side engine casing which is very simple but has harmonious shapes, I liked the Benelli writing in relief. For many it is certainly simply an "engine crankcase",     I like what I can tell you...

There will be some tests to do before arriving at the final piece, even in this case I will make not many numbered pieces (1/20), also because the mold is delicate, after some time it begins to deteriorate.

If you would like to leave a comment, a suggestion, your personal opinion, please do so, it is always useful.

I found some problems in the plaster mold, precisely in the holes used for extraction, the initial repair did not allow the water to absorb well, with the final result that the piece (engine crankcase) was deformed. It seems like a small spot, but it creates a problem in the finished piece. Sanding everything, I redid a plaster cast inside the hole, smoothing everything at the end.

I am of the opinion that even a mechanical piece has its charm.
This is the reason why I want to reproduce the side casing of a "Gilera Arcore", produced from 1972 to 75.

Initially the piece was completely solid, it was very heavy and a waste of material.
With a second test I did it with the casting system (slip) so that only the edges show a thickness, I like the result...

Once the slip casting slowly dries in the air and hardens, the piece detaches from the mold because the water contained in the slip is absorbed by the mold itself, creating a vacuum, after which you just need to turn the mold upside down and you're done.
By mistake I created a hole that I had to repair with another pour of liquid clay.
Finding the ideal thickness is not easy, the piece must be resistant at the same time as not coarse.

(learning by doing errors)

The piece looks good when it comes out of the mould, once dry the piece loses around 10% of its size and is slightly smaller. The original holes were made.

Personally I prefer to clean and smooth the ceramic once it is dry, with very fine sandpaper I can eliminate small imperfections.

Drying the ceramic is very important, the piece must dry slowly, it should not be placed directly in the sun, so it takes a few days and a lot of patience. On one crankcase I didn't take the central weight into account, and therefore as it dried the central part collapsed slightly.

The last stage is cooking at 1000 degrees centigrade.
I'm undecided whether to leave the raw piece in a ceramic colour, or to enamel it...

In recent years I have become passionate about urban landscapes, both citizens and abandoned works, old Italian restaurants, old service stations, small city shop windows that have now disappeared but have their own hidden charm...

They are small works carried out on cardboard, with markers, pencil, pen, mixed techniques including watercolour, if you wish to leave a comment feel free.

I attach some photographs of my finished work.

I wanted to reproduce the BING because it is one of the carburetors that I like most aesthetically speaking.
I deliberately left the original color of the ceramic, I only gave it a coat of stain to darken the ceramic joints.
Naturally, ceramic can be painted as desired with any color, even enamelled.
If you like the piece and are interested, give me a shout!

The measurement is taken from the original carburettor, once dry the ceramic shrinks by a small percentage compared to the original piece.

Original carburettor

I wanted to do a different test, open the carburettor where the filter and manifold would go, this way the piece is perhaps lighter...

Janus is an American motorcycle manufacturer, their headquarters are in Indiana, they offer completely handmade  motorcycles  with a unique  and  retro style.  Personalized Janus Motorcycles  2023 annual event poster. The work was done on rigid cardboard with acrylic colours, nothing digital, just old pencil, eraser and colours.

The clay parts are dried for a few days, they are fired, once the clay is cooked the pieces are solid ready to be composed.
They can be left raw or painted
In the last phase, all the pieces must be assembled with a two-component glue, then it will be mounted on a pedestal.

The composition of the carburettor and all its parts is finished, the last phase is cooking at 1000°, we're almost there...

                       

        Each piece has been finished by hand, once finished it will be assembled and placed on                                           a pedestal, of course it is just an ornament! Petrol is not needed.

Some compositions with newspaper sheets, scissors, a bit of vinyl glue.

VE LA RICORDATE?!!

Questo è il mio ultimo lavoretto grafico realizzato completamente a mano, visto da vicino le imperfezioni non possono nascondersi come i segni del passaggio di pennarello della matita delle cancellature varie, ma detto sinceramete, poco mi interessa...

Spero possa piacere, i commenti sono sempre ben accetti naturalmente.

 

Grazie a tutti per la vostra visione!
