Carb Casting Repair, Zinc Solder?

Hats off to you

Proprietary : something that is used, produced, or marketed under exclusive legal right of the inventor or maker. ( sometimes loosely used )

Chromate conversion : The formulations typically contain hexavalent chromium compounds, such as chromates and dichromates.  hexavalent chromate No longer legal in some areas.
Trivalent passivation/conversion coating. Now used to comply with environmental standards. I believe the Caswell system uses this.
There is nothing proprietary about the way I prepare a carb for restoration. I use hexavalent chromate, the same as these carbs were done when new.
Some carburetor parts were zinc plated , some zinc with chromate finish, some parts were black phosphate finish.
I have a local plating company do the finishes, after I prepare the parts ,that has been in business for about 60 years, from father to son. They are very knowledgeable.
It is almost impossible to duplicate the original finish of the castings .
It is very time consuming to restore and correctly calibrate these old carbs. You have to enjoy helping people. I don’t do the internet thing, just word of mouth and car shows.
Below are a few carbs I have done recently. They may be correct, or not.

Kinda' like what the owner of a particular nearby business experienced when he failed to have his employees sign a non-compete and non-disclosure agreement. He simply trained them to open their own copies of the business. Oddly enough, he had expropriated his knowledge of the business in the same manner.

England in the 1920s: my Grandfather, who worked in a trade* starting at the age of fourteen, related to me how some workers would turn the torch on you lest you learn fine details of soldering castings** and put their continued gainful employment at risk.

* Trade: trade-secret. Get-it?

** Tying together this technical milieu, right?

I'm not sure what you were trying to get across with the above . Wouldn't it be reasonable to say If you wanna keep trade secrets then don't join the discussion.

Simply that "trade secret" is a more useful term to use than "proprietary"; in my opinion.

Interesting to follow the etymology of words and their colloquial usage.

Boy, did I catch hell when in another forum I attempted to describe the aforementioned English worker as "protecting his rice bowl." It triggered an automatic response from the AI agent monitoring postings. What a golden age we live in.

Carry on.

Nothing is secret, it's just stuff we haven't learnt yet.

Yes, it is a golden age we live amongst now.

Maybe that stuff works, maybe it's pure magic, but I haven't seen anyone use it for anything other than sponsored promotion type stuff (it seems to be made for doing that more than anything else).
