BUGATTI T46 "Surprofilée" 1:8


Recommended Posts

  • 2 weeks later...

Hi everybody!


I told you about the central crossing, a small world all by herself ...
Here it is. And it lacks the pedals!

In the foreground, the belt tensioner of the enormous dynamo that will take place on his bracket, on the right:

The mechanism of the cable brakes a small poem also ...

Normally, this part is chain based. We forget! The cable will do the trick:

And of course, we complete the rear deck with its tie rods:

Some pieces, in bulk ...

The last ones are for the front axle ...

The cable is not suitable for my taste, it will be changed ...


Have a good week!

Propeller I was slightly afraid this build was going to be equally slightly less spectacular than the Talbot-Lago's, especially since a lot of the Pocher stuff seems to be already good for unmodified use out-of-box (after a bit of tweaking to each part, as I learned from Mr Codger, as no single parts seems to completely fit) but you don't disappoint, again! This build is very much worthwhile following.

 

And I do like your poetry.

Thanks Pouln, it's my challenge...

 

Well, after the front axle, the rear axle, the chassis, what next? It's time may be to the engine, first the engine mounts:

It was a big milling chalenge for me...
Here, front mounts:

Thank you very much Keith!

 

With the hydraulic shock absorbers, the rear axle is completed!

The retaining straps will be tight later...

Another milling challenge!

Many foundry parts here, as this cross piece. Not very easy!

Not 100% accurate, never...

Leather straps to limit axle movement.... You are showing us the model, are you. These are not pictures you took in the local Bugatti resurrection garage?

What a joke Poul... Unfortunately not!

 

Well, today, battery tray, a box in fact:

With some improvements...

Next challenge, exhaust. With an oddity, again!
Made with an hight technology tool...

Dan are you sure there is only one battery box? When I visited the T50 I noticed there were two similar boxes like that, each under one seat.

 

Of course this could be different on the individual car you are replicating.

 

See the discussion in Crazycrank's topic about the battery box(es).

In the Louwman car there is a similar box underneath the passenger seat. 

 

There are therefore two more or less identical boxes. I didn't see the battery or batteries so I don't know if one of the boxes did not contain a battery.

If I can provide my opinion, or more my certitudes

 

On the Louwman's Bugatti T50, there is two similar boxes, a bit shorter, one of each side, and I can affirm without any doubt they contains both, batteries

Indeed, I've studied your photos, and we can see, among other things:

- From the left box, an electrical black cable that runs to the electrical starter.

- From this left box, an electrical red cable that runs to the right battery box.

 

On the Louwman's Bugatti T50, the two batteries were 6V each, and were connected in series, so tensions added, and the two batteries provided a 12 V tension.

 

BUT, if the first T50 chassis (n°50112), and the T50 sport chassis had also two batteries housings, they were both on the right side of the car ! And contained each one a 6V battery, connected in series to the other one...

33191739246_4e9a72f4c9_c.jpg

 

 

 

 

 

 

I think, having studied reference photos, that the reason is the exhaust muffler was very long on this chassis, running forward to end at the clutch housing level, contrary to the Louwman's T50

The muffler took all the place o the left side of the car.

 

On the T46, as far as I know, there is really only one battery housing on the right side, that contained....I think two 6V batteries, connected in series.

 

On the T41 Royale Bugatti, there was, as on the first T50 Bugatti, two battery housings, on the right side, and they probably contained both, a 6 V battery, connected in series to the other.

Hi gentlemen!

Today, around the chassis, more. the goal is to put on the chassis all _ I hope _ the components before the assembly of the front and rear axles... Of course, to reduce further manipulations!

Today, muffler.
Brakets:

Ready to go, before paint...

In situ, definitively...

Next? Gas tank...

Thanks for looking,

As promised, gas tank...

An annealed sheet of brass, and let's go:

Ready for paint, with its metallic straps:

And definitively on the chassis:

You are doing some great work on the scratch built brass parts! I have a quick question about the type of solder and flux that you use on the brass. Are you using a 50/40 or a 50/50 solder or something completely different? The other question is on the type of flux, do you use a liquid and a needle applicator or just a brush on type? Up until now, I haven't done much more than solder electrical wiring but, my upcoming build is going to require a bit of brass and PE soldering and a chance to use the new resistance soldering station. Thanks, keep up the great work.

Thank you very much guys for your kind words!

To larchiefeng, my different solder:

 

529295DSC0004.jpg

 

Green one, standard, on the left, f= 180°C tin 60%, lead 40%, on the right f=145°C, tin 43%,lead 43%, bismuth 14%.

I got some years ago an American Beauty resistance soldering station! The same? Very useful for tinny pieces...

 

Well, today, pedals...

On the left clutch, brakes and throttle. All different!

Settings, always...

Brakes differential mechanism, cable brakes you know...
