[Fiat 806: research and scratchbuilds]

I have just got Paul's reply about the thin thread running on the Bugatti (and the 806, see above):

 

Dear Olivier:

This is safety wire to prevent the bolts from turning and becoming loose. Apparently this was a big problem from the rough roads on the Targa Florio. The collection car here was driven by Chiron in the 1935 race. Note the bolt head construction. Bugatti was famous for having propriety fastners even to a odd screw pitch for the threads.

 

The best 

 

Paul

 

Very interesting reply, thanks again Paul! So, the 806 bolts were probably different from the Bugatti's...

The type of bolts has nothing to do ... These cars were subjected to strong vibrations, which regularly unclamp all nuts and bolts!

Thank you Keith, much appreciated!

 

What happens?

 

 

Since the beginning, this front train obsessed me. His camber was obviously wrong.

 

 

On the model, 0°:

 

 

After some work, it's OK for me!

We were in settings...

 

 

Both sides have bee amputated:

 

 

The result, not 100% accurate_ who said never?_ is acceptable...

In fact, it was very simple...

[Fiat 806: research and scratchbuilds]

Thanks for the medal Olivier!
If I tell you Bugatti for the make of this car, did you trust me? You can... But lot of makes used this kind of fixing. 

[Fiat 806: research and scratchbuilds]

Spring inside!

[Fiat 806: research and scratchbuilds]

I agree Olivier! For fixing the bonnet you can play with the flexibility of the plastic...
Both side of course.
Dan.

 

[Fiat 806: research and scratchbuilds]

Thanks Harvey!

Olivier, about your problem, the spring may be into a metal tube...

[Fiat 806: research and scratchbuilds]

In my opinion, this little tube is simply a thermometer, so (or a part) glass to see a level ...

An example:

Regards, Dan.

Today, first take a look to springs, they will be invisible soon...
 

 

She is now in french "dans ses lignes"...

 

 

The back of the Pocher's "Surprofilée", a pity... Nothing!

 

The real car:

 

And a real challenge!
It's not achieved...

Well, when i setted the fenders the first time it was evident that the rear was wrong.
Wrong cutting, body too low...

 

A little bit surgery for the first point

 

 

 

 

For the second point, I know the two guilty, the leaf springs.

Everything wrong, shape and thickness!

The real thing, on a 50':

 

Found on Ebay another pack...

 

 

Now, it's OK? Maybe a small gap?

 

Let's go...

 

Dan.

[BUGATTI T46 "Surprofilée" 1:8]

Of course Codger, it is sufficient to orient the guide ruler of 11 °...

 

 

And thanks for your kind words!

Dan.

[BUGATTI T46 "Surprofilée" 1:8]

Well, today louvres, my way...
 

At home, no press tool, but a milling machine! Lets go!
Be careful, some people may be chocked...

 

First step, block the rotation: 

 

Second hijack a flying cutter!

 

 

More traditional...

 

Dan.

[BUGATTI T46 "Surprofilée" 1:8]

Thank you very much gentlemen!

 

Today, return to the jig. I have to realize a part, missed by Pocher and make the new fits for the fenders...
 

 

 

The"new" part, settings:

 

 

Ready, in situ:

 

 

Of course, I can't solder. Another cheating...

 

 

 

Dan.

[Fiat 806: research and scratchbuilds]

Hi Olivier, and congrats for your work...

About the first pic "Quelle est le role exact de cette piece?", you can see nearly the same on the Talbot:

 

 

Dan.

[BUGATTI T46 "Surprofilée" 1:8]

First piece of the bonnet almost OK, on the hinge...

 

 

 

 

 

Dan.

[BUGATTI T46 "Surprofilée" 1:8]

Merci Pascal!

 

About engine turn pattern, more...

What I hate:

 

 

Today, bonnet...
Aluminum sheet 0,4mm annealed, of course...

 

 

 

 

 

 

Dan.

[BUGATTI T46 "Surprofilée" 1:8]

Erratum...

25mm:8=3mm

[BUGATTI T46 "Surprofilée" 1:8]

Well, I can't give in english a reasonable answer to CC.

I'm sorry but the following will be in french!

May be CC will translate that for you. Thanks by advance...

 

Toutes les Bugatti restaurées ont ce fameux "bouchonnage" ou encore sur les moteurs

ces "grattages" manuels, ces derniers encore utilisés sur les machines outils de grande précision.

Je ne sais si ces artifices cosmétiques étaient demandés par les clients ou proposés par l'usine,

mais ce dont je suis certain c'est que ce n'était pas une règle...

Mais Pebble Beach est entre temps passé par là!

D'autre part, pour l'avoir mesuré, ces marques de bouchonnage excédaient rarement 2,5 cm. Ce qui

donne au 1/8 ... 0,3mm! Pour moi irréalisable...

Et pour terminer, je dois humblement l'avouer, je n'aime pas cela!

My God, I'm starting to really understand why you wanted to use 1/12 scale for your Delage ...

[BUGATTI T46 "Surprofilée" 1:8]

Hi gentlemen and thank you very much Roy... 

I'm not sure I deserve the title "master", but I'm very touched by your intervention!

 

Today, radiator in the good shape and more leather pieces...

 

 

 

 

 

 

Dan.

[BUGATTI T46 "Surprofilée" 1:8]

Thank you very much Roy for your kind words and your humor. It's only an approach of the reality!
Never hundred percent accurate, never... 

[BUGATTI T46 "Surprofilée" 1:8]

Thanks Keith, much appreciated...

Today wires, linkages and some plumbing...
 

 

 

 

 

As usual, some hours spent for that:

 

 

Thanks for looking...
Dan.

[BUGATTI T46 "Surprofilée" 1:8]

Thanks Roy...

 

 

Something new today, steering gearbox, and is was not a small business!
 

 

 

For the machinists, my friends...

 

 

Steering arm, not really easy! 

 

 

Of course, now, firewall is coming too...

 

Thanks for looking,
Dan.

 

[BUGATTI T46 "Surprofilée" 1:8]

Hi gentlemen!

Around the engine, more...
But now on the chassis!
 

 

Some wiring perhaps?

 

Carburetor is also here :

 

Exhaust side... 

 

 

How to?

 

 

Carburetor in pieces... Without hardware!
