1:12 1932 Cadillac V-16 frame and engine

[Roger Zimmermann]

The construction of the model resumed slowly after our return from France; the second intake manifold is done. I will now try to replicate the carburators, the "fun" will begin!

Very interesting proceedings. Markus

[Roger Zimmermann]

Thanks Markus!
Due to other tasks, the progress is slow on the scale model. I'm doing now the throttle bodies; the one pictured is not yet ready. There are some important details to add...

[markus68]

Not ready but impressive. The progress on my model is also slow. Markus

[Roger Zimmermann]

This is what I intend to replicate. Wish me luck!

They almost look like a pair of espresso makers! Amazing to think they ran a 16 cylinder engine with 2 one barrel carburetors to move such a bug heavy car.

[Roger Zimmermann]

When enough fuel went through that single barrel, it would move! I agree with you: the power was modest: 165 PS at 3400 RPM. The intake manifold is also something not created to have a similar fuel/air mix for all cylinders: the tubes were short at the center and very long for the outside 4 cylinders (per bank). However, by looking at various brands, it was done that way during this time.

I think it´s for another car this carburator

perhaps that one


...... because still thursty ............

Roger , for easy building of the carburator just cut it out from paper as shown and glue it ............

[Roger Zimmermann]

Good idea Freddy!

[Roger Zimmermann]

The next parts I did are the air intakes which are attached to the throttle body with two screws. That is way not finished, the float chambers must be attached to the air intakes.
As it can happens, I did a major error with the first set of air intakes. The diameter was too large, more than 1/2 mm. I wondered why I has so few space for the screws at the flange...Obviously, I took the dimension from another similar part. Silver soldered parts can be separated to save some elements, but in this case, I preferred to redo all elements because all was too much concentered.

[PaulPK]

Looking good Roger. 1/2 mm can really make a difference. I feel your pain having to rebuild a part . But bin there done that ��

[happyfreddy]

second problem for You Roger is , that both carburators look different so You can´t copy

[Roger Zimmermann]

Paul, I suppose everybody is confronted with that kind of issue. I just had to redo both parts!
To Freddy: indeed, there is a LH and a RH carb. The ground parts are identical, I just have to be awake when I'm silver soldering elements together to really have two different carbs!
The next job was to do the float bowl; each one is constituted with 5 elements silver soldered. By looking at the drawings/pictures, both elements are not at the same level, therefore I had to make a tool allowing me to screw both elements on the tool for final soldering.
Both pictures are showing one assembled carb and the other one on the tool as well as both carbs.
There are still numerous small details which will be either silver or soft soldered.

Nice work Roger!

An aside, when did air boxes and filters arrive on the scene? At the time these cars were made here in America, city roads were paved of course, but country roads? -much of those were still dirt.

[Roger Zimmermann]

Thanks Don!
I unfortunately don't have the answer to your question. I can just put a picture from the air cleaner (1 each side) as installed on the cars from 1932-33. According to the parts listing, the V-16 from 1930-31 had no air cleaner.
