Gilera Bi4 Nordwest 3d scanning/modelling

[Duranti]

Good day Maurizio, and Gilera friends!
Thank you for asking about news Maurizio, I appreciate it, and I was actually going to post pictures later today, and I will! 

Things have been going slowly lately, I have had a couple of customer projects going at the same time I have been working on the carbs, and I have to say; I truly underestimated the amount of work required to accurately model the carbs, they are a whole project in their own right!

Currently I am working on the last small bits on the left side carburetor, and it is quite complicated, since it is a die-casting it has drafts on most of the geometry, which takes longer to blend the features properly, but I'm almost finished, and the carbs look very good!  I am finished with the carbs once these last bits are in place.

At the same time I have been working on the new Nordwest inlet manifold, and I am currently sending quote requests for manufacturing of the parts. Soon I will have prices, to see if it will be possible to produce a couple of prototypes without breaking the bank, before producing a series of manifolds for sale. 

Thank you all for your patience in following this lenghty thread, you guys inspire me to complete this engine to the highest standard I can achieve!

Fine, thanks for the updating.

Ok, Trond, let's wait for the carbs

[Duranti]

Good evening friends,

Sorry for the long wait, finally I was able to finish the carbs after much more detailing than I initially expected, wow, the carbs look quite simple, but they are in fact very complex!
I can only imagine how complex the die-casting dies are for parts like this, they must be a piece art to produce these intricate casting, very impressive!

For scanning the carbs I had to disassembled the carbs from the mounting rail to enable as good scanning coverage as possible, even then it was difficult to access all the geometry, but I was able to manually measure the geometry that was missing from the scan, so the final result is very complete and accurate.

Reproducing the carbs in 1/3 scale will be the biggest challenge yet in this build, I am considering splitting the models into several different parts to enable printing of these tiny parts, it will be very difficult, but I will give it a try, hopefully tomorrow I will start printing.  I might have to merge some geometry to enable printing, but I will try my best to get the best possible detailing in the 3d print.


Hope you enjoy the pictures, I am signing off for tonight, have a great evening friends!

PS: If anyone has a defective starter motor (and bracket) for sale, please let me know, I am interested in purchasing (to complete the model).

Trond, really impressive, that's a great work

Immaginatevi di avere un kit da costruire il motore completo in scala del BI4 da tenere su un tavolo, scrivania!
Sarebbe fantastico.

such a great work! 

now the real challenge will be printing, I'm confident it will be another success.... go Trond, go!

Thank you my friends for your kind words and inspiration!!! 

I am still planning on the best way to print these carbs, I believe tomorrow will give some results, and prints, I will post pictures are soon as I have something to show you guys!

Chi mi traduce in inglese la seguente frase per cortesia?

"porcaschifadiquellaput...nazza che lavorone!!"

[bigbore]

pronti!

"lousysowofthatbitch.... such a great job!"

Sì, gli anglosassoni sono molto pratici. Poche lettere: "Fuck, what a job!". Ma anche noi in questi casi abbiamo la forma breve: "C@..o, che lavoro!"


Sorry Trond for the quick Off Topic ...

Hahaha, no worries, I enjoyed reading it (thanks to Google Translate) 
I am working on my very limited Italian, I mostly just know the italian names of motorcycle parts, haha, it's a start at least!
