Gilera Bi4 Nordwest 3d scanning/modelling

[33new]

Great job Duranti, you are one of us! You aren't a simply gilerista, but  you are a really gil-erotic! Do you understand?

    

[Duranti]

Good evening 33new, thank you for your excellent comment, I really appreciate it!

Yes, our love for the Bi4 is genuine, I have been a big Gilera fan (especially all Gilera Rally, and Bimota GB1) since 1989, and consider myself crazy about Gilera!

Latest updates on the Bi4 engine scanning/modelling! 
The left hand crankcase cover is full of details, I am very impressed by how clean the cover looks despite of all the details, drafts, fillets and so on, and I have only tried to replicate just the outside surfaces!

Great work

[Duranti]

Thank you for your kind comments, much appreciated!
I have some experience with steel castings, but the Bi4 parts are more complex than I initially expected, and also the esthetics of these castings is magnificent!
I get the feeling that there is both work by machine, as well as hand, to complete the molds to created the castings, absolutely wonderful engineering, it is easy to see that there is alot of passionate work put into the Bi4!

Another update; the iconic cambelt cover! 

[Duranti]

Just wondering; does anyone know which font is used for the Bi4 text on the cambelt cover, I can't seem to find it anywhere? 

[Matte]

I don't know if it's simple to find this information, I hope someone can help you.

uhmmm... could be a slightly modified original font.

Gilera font has change during the years, let's say that until late 80' the font was "clarendon serial  heavy"
later, appearance changed slightly.

A font can be downloaded from the other gilera fan forum: http://www.motoclubgilera4t.it/forum/index.php?topic=2043.0 but i don't know wich one it is.


othervise give it a try to this: https://www.fontsquirrel.com/matcherator

Thank you Matte and bigbore for your help, it is much appreciated! 

The original Bi4 logo seems almost like custom letters specifically made for this logo, I will try to run it through the matcherator and hopefully find the right font, thanks again!!

[bigbore]

chances are that the mold was modified by hand later.
I'm not sure (can't check right now) but my belt cover don't have that logo

[Duranti]

Thank you for the interesting post bigbore
If I remember correctly the covers came in natural black, painted grey/silver, as well as the split cover for the Saturno, but I was not aware that there were covers without the text, nice, I will have to do more research on that, thanks 
Also, I have decided to trace the text for the Bi4 logo since I am unable to find the correct font, but it should be easy to make.

I've checked both beltcover in my possession, non logo Bi-4 on it.
Let's see what other Bi-4 owners have to say about this matter.

Hei ragazzi, ve lo dico in italiano così non avete scuse: il carter copricinghia del vostro Bi-4 ha per caso impresso la scritta Bi-4?

indicate moto e versione motore please

[Duranti]

Thank you for your effort bigbore, I appreciate it, and I look forward to seeing what people say about this! 

I traced the logo, and made a cad version, there are some small deviations, mainly due to the small size of the letters (and slight prespective of the picture), the letters are approximately 14mm tall, however it's beautiful how the machining details are captured in the pressure cast plastic!
