Procedural Pete Posted March 23, 2016 Share Posted March 23, 2016 Question for those in the know. Is the Uberti 1873 hammer and upper trigger (sear) hardened steel or case hardened mild steel? Link to comment Share on other sites More sharing options...
Larsen E. Pettifogger, SASS #32933 Posted March 23, 2016 Share Posted March 23, 2016 It is just surface hardened. If you stone the sear and go through the hardening it is soft and will wear quickly. Link to comment Share on other sites More sharing options...
Garrison Joe, SASS #60708 Posted March 23, 2016 Share Posted March 23, 2016 Yep. I keep a can of Kasenit around (unobtainable any more, ) to reharden these parts when I recut the poor angles that the factory usually cuts into them. Good luck, GJ Link to comment Share on other sites More sharing options...
Palo Verde, SASS # 56522 Posted March 23, 2016 Share Posted March 23, 2016 Yep. I keep a can of Kasenit around (unobtainable any more, ) to reharden these parts when I recut the poor angles that the factory usually cuts into them. Good luck, GJ Mr. Joe, (and perhaps Larsen, although I can ask him FTF) case hardening these parts after they are worked is a fine thing indeed and if that is your practice, you are a fine man indeed. But, are you saying you have found these parts to be hardened from Uberti ? If so, perhaps you have seen something differently than I have. I have not run hardness tests on these parts other than the old "scratch it with a file test." I know you too have seen many of the Uberti Rifle "Kits" but I have not seen anything that I would consider "hardened" in a Uberti Rifle Kit and I am aware that the Uberti folks have often said that it is their opinion that "you don't need to harden parts if you use good steel" . (P.S. I too secure my one can of Kasenit. ) . Link to comment Share on other sites More sharing options...
Garrison Joe, SASS #60708 Posted March 23, 2016 Share Posted March 23, 2016 Now, I don't have a Rockwell hardness tester either, but I do know that when I cut on Uberti trigger/hammer parts with a file or stone, they feel pretty soft to me. So I surface harden them when I get done. I don't think they are using 4140 or some of the 8600 steels for these fire control elements. I sure would. Then they could be thru-hardened after machining. (Would be some fine parts for a pard to start making with a CNC mill and a grinder and a heat treat oven.) Good luck, GJ Link to comment Share on other sites More sharing options...
Springfield Slim SASS #24733 Posted March 23, 2016 Share Posted March 23, 2016 The hammers in my Uberti's seems to be hardened, but the sears are much softer. Seems like the intelligent way to go, as I would rather replace sears than hammers. Out of my 6 rifles, 5 have hammers with a decent angle, but the last 73 I bought is just terrible. I am going to have to do a fairly radical re-cut and re-harden on that one. Didn't realize Kasenit was no longer available, but at least a can lasts a good many years.

Larsen E. Pettifogger, SASS #32933 Posted March 23, 2016 Share Posted March 23, 2016 My can of Kasenite is at least 15 years old. This stuff looks like a good substitute. http://www.brownells.com/gunsmith-tools-supplies/metal-prep-coloring/color-case-hardening/surface-hardening-compound-prod27119.aspx Link to comment Share on other sites More sharing options...
Colorado Coffinmaker Posted March 23, 2016 Share Posted March 23, 2016 It was my experience pre retirement, the Hammer was Case Hardened. It was not hardened very deep. The Uberti sear did in fact "feel" harder than the rest of the part. I didn't then, nor would I bother now to work about a "hardness test." Just harden the wear point of the parts when you finish and be done with it. Same position as GJ, I prefer to have a trigger wear than a hammer. Trigger is much cheaper.

Procedural Pete Posted March 23, 2016 Author Share Posted March 23, 2016 Thanks for the input. I have a can of Brownells Surface Hardening Compound. I will put it to use. Link to comment Share on other sites More sharing options...
Hurricane Deck 100366 Posted March 23, 2016 Share Posted March 23, 2016 Any of you guys using Cherry Red? It's basically generic Kasenit. Looks and works exactly the same. I replaced a can of Kasenit that was accidentally thrown out by an ex. I've been pretty happy with it. Moral of the story: Don't throw out a man's Kasenit.

Garrison Joe, SASS #60708 Posted March 23, 2016 Share Posted March 23, 2016 I replaced a can of Kasenit that was accidentally thrown out by an ex. That would be an action that would harden my heart. Good luck, GJ Link to comment Share on other sites More sharing options...
Boggus Deal #64218 Posted March 23, 2016 Share Posted March 23, 2016 That would be an action that would harden my heart. Good luck, GJ Joe, that's just bad. Link to comment Share on other sites More sharing options...

She tried to explain that she thought it was all used up because the can was so old and had been "left open" it was the beginning of the end!

Muleshoe Bill SASS #67022 Posted March 23, 2016 Share Posted March 23, 2016 Kasenite is straight sodium ferrocyanide. It produces a carbo-nitride case. Sodium ferrocyanide is available as yellow prussiate of soda Link to comment Share on other sites More sharing options...
