I know this isn't a refinishing question but I figured that an expert in refinishing would be able to best answer my question. Is the case hardening on Uberti guns real case hardening or just a chemical finish? How is the chemical finish applied? I understand how real case hardening is done.
I won't say for sure, but I don't think it is. I spoke with the people from Cimmeron at SHOT and they send guns to Doug Turnbull to have real case color done if the customer desires it. Whatever they use is more durable than the fake case color on the old Ruger Vaquero I had though.
Nah. Real color case hardening require a crucible, charcoal and a furnace. I've never done it, but they pack the gun part in a crucible with different types of charcoal (leather, wood, or bone), and put it in a furnace for a couple hours at about 1400-1200*F
Then they quickly drop the part in water. I've heard of some people using some kind of oil...but I cant be for certain.
There are other ways to Color case harden, but this is most common:
Some people do Cyanide color case hardening, which creates a tiger-stripe look.
The Tiger Stripe case hardening is done by dipping part of the hot metal in the water, then pulling it back out, then putting it in a bit farther, and out again. Think of it as two steps forward one step back. It's true that some people do use cyanide, but that is to increase the number of colors that come out. To increase the amount of color that comes out you have to break up when the water hits the metal. You can wrap the metal in a few layers chicken wire, this breaks up when water reaches the metal pretty good. You should also arrate the water before hand.
