Gilera Bi4 Nordwest 3d scanning/modelling

[Duranti]

This model is 100% dedicated to my love for Gilera, and it is very enjoyable for me to show my work to fellow Gilera enthusiasts! 
When the model is finished I will make a proper presentation for the model, and people in the forum can help decide an eventual price.

Splendid work, Duranti . This is a small step for a man, but a great jump for gilera's enthusiasts........ . Bravo,  bravissimo

[Duranti]

Matte, I truly appreciate your kind comment! 

Today I'll be printing the cylinder, hopefully it turns out nice, I'll be posting pictures when it's ready! 

[Duranti]

I finally got some more parts printed!
The new parts are; cylinder, cylinder head gasket, oil filter and filler cap.

Next up is the thermostat housing mounted on the cylinder, and after that is the gear lever.
I'm waiting for a new sprocket to arrive in the post, as well as some other small parts. My plan is to incorporate a bearing to enable rotation of the sprocket, should be a nice little realistic effect. 
For the side covers I will be using a gold pearl ABS filament, should make for a good finish and look of the parts.

The plan for this project started with making a complete 3D model for using in a design, but now I'm having so much fun putting together this little model, and it is taking over the priority!

Slurp, slurp, it's growing very well

Very very good

[Duranti]

Thank you all for finding my project entertaining, I really appreciate it! 

Got the right hand side crankcase printed today, it took around 9 hours!
I am pretty happy with how it turned out, some small defects due to support material density (PLA), but I will solve this when printing with ABS.
The pictures show good detailing despite printing in "normal" mode on the Ultimaker 2+, and only the smallest of details, like the text right below the cylinder, was automatically merged with the rest of the geometry. Overall the result was acceptable!

Before I print the left hand side crankcase I need to get some details in place, like the sprocket, seals and shift lever shaft, because there is going to be some movement in the sprocket and shift lever. 

The last picture shows my "workshop", haha!

[vninja]

Fantastic, very beautiful. You are as a wizard.
beautiful too your workshop!

[Duranti]

Thank you so much for your kind comments vninja, I sincerely appreciate it! 

I am doing my best possible work to honour this legendary engine, and I am having alot of fun seeing these small coming out of the 3d printer!
Hopefully I will have more parts ready this week, stay tuned! 

[Matte]

Amazing, Duranti, congratulations, the "little" engine is becoming real

[Duranti]

Matte, thank you very much for your kind comment, I am glad you are enjoying the progress of this project! 

I got the thermostat housing completed today, a small part, but it is a sweet little piece of engineering, very well made and built to last. I will try to 3d print the model today.

shame on me for not following this topic as it should deserve
Eager to see that great final result.

IMHO you should change your name from duranti to Canova.... (https://en.wikipedia.org/wiki/Antonio_Canova)

Impressive work ... wow ...

[Duranti]

@bigbore / @Mike58 Thank you for your kind comments, very much appreciated, I am humbled!   

Eventhough this process, of scanning/measuring/modelling and printing, has taken much more time than I intially anticipated, and it's been very challenging, I am still only trying to replicate the outstanding work of the engineerings/designers/craftsmen who did this fantastic work before 1985 (!), which is amazing to me considering the availability (or lack of) of 3d modelling software, casting simulation software (like Magma), and so on in the early 80's.
I have personally designed complex steel castings in my previous work, and I can appreciate the amount of work it takes to go from idea to finished product, and how many iterations a part goes through before it is ready for series production, it's a very elaborate process. With this in mind, I can only marvel at the skill and determination it takes from all the people involved in designing/manufacturing/testing and series producing an engine like the Bi4, it is a huge task, and I have the greatest of admiration for these people! 

It's been slow progress lately in my project, I am waiting for parts to arrive, but I am well under way with modelling the sprocket cover, and some small parts. Today I will be printing the round oil pressure switch cover located under the alternator cover (PN 321715). I've been trying to find this cover on Ebay, but I've been unable to, so I have 3d modelled it based on dimension given by CFASD: http://www.gilera-bi4.it/public/forum/index.php/topic,12082.0.html
If it prints ok and fits nicely, I'll be sharing the 3d file for anyone to download and print themselves
