1:12 1932 Cadillac V-16 frame and engine

Roger, I think both carbs are in main things equal. The posted pic shows them in special way.
So I would copy the pic and cut off each carb on paper . When putting right over the left part
perhaps You recognize they are in most details equal.
I think the right carb stands not in 90° like the left one . The top flange must be equal at both
parts. Because of the perspective pic it seems that the base connector at right carb is different
from left carb.
But for me its only screwed in another position so You can´t see the screw connector like in
right carb.

I hope You have a detailled drawing of those parts like blue print ones
good luck !!

Interesting!

Each side of the engine had it's own intake system.

Wow! Look at that distributor!

Tuning this engine must have been a joy!

To Freddy
That's correct, most parts are identical, left and right. Only details differs like a hole here or a longer casting there. Difficult to see on my pictures. Anyway, when all is assembled, there will be a LH & RH carb. I don't have blueprints, but good drawings from the shop manual.

To Don
I suppose not every mechanic from a back yard garage could properly tune such engines!

The main body from both carbs are ready. Some cleaning finishing will be necessary before paint. Now, I can continue the throttle bodies as the main bodies will be a guide to attach what's still missing on the throttle bodies.
Of course, I still will have to fabricate the external elements like metering pin, inlet etc.

No floats?

[Roger Zimmermann]

On my last picture, the assemblies are upside down. The floats are located into the chambers at the right. Can you not see them?

[MODEL A MODEL]

Oh of course!

I see them now!

Your the best!

[Roger Zimmermann]

Finally, I could finish the "casting" from both carbs. As I wrote earlier, some minute details were skipped. One of the most difficult element to be added to the throttle bodies was the accelerator pump castings. Thanks to the main carb on which the position of the accelerator pump was well located, I could do a fixture with a long screw giving the location in the space for that small "casting". This is the first picture.
As the accelerator pump casting was threaded, it could be vertically located at the right place. Then, it was a matter to do a spacer, adjust it at the proper dimension and silver soldering it on the throttle body.
Now I can do the various element which will be screwed on the carbs.

Roger , are You sure the fuel will flow through that small carburator
in proper way ??
I ´ve heard, that - because the price for fuel get´s higher day for day -
the petrol industrie decided to make the fuel molecules a little greater
to earn more money for less fuel...........
perhaps if You install some debris filter You can get problems with
fuel flow.............

in other way Your carburator looks nice and top made so any fuel will
like them..........

Watch out for the Ethanol fuels - they eat away at the solder joints. Restored classics tend to use plastic floats, not brass, for this reason. Have you considered plastic floats?

[Roger Zimmermann]

@ Freddy: That's a valid concern. I suppose that there will be a lot of vapor lock during warm days!

@ Jo: I was not aware of that situation. I may redo the floats!

[Roger Zimmermann]

Carbs making is not very exciting. Plus the sale of one of my old cars was a real "distraction" for more than one month. Anyway, I did some small additions like the accelerator pump, which is in my case just a rod as well as other small details you could maybe catch on the attached pictures. The float's cover is attached by fake screws.
I still have to make the butterfly shaft and levers.

[MODEL A MODEL]

Really very nice work Roger!

Getting the proportions right, maintaining hard edges where they're needed and proper radius on other components!

I think it's exciting! (But then I'm a modeler)

Thanks Don!

Finally the carbs are over. I skipped some details as well as all springs because they are so small it makes no sense to add more complication. The actuating lever is a strange one, its shape is dictated by the exhaust manifold. Nothing is moving on the carbs; shaft, accelerator pump lever, idle lever and actuating lever are all together soft soldered . Once the carbs are installed, almost no lever can be seen as they are facing the engine.
