Doug;
I relly don't know why you even thought I was making a personal attack on "Your" work, I did not intend to come across that way. I did indeed read that post & the depth you said you acheived. Now 1.2-1.5 mm depth is indeed good depth. I was in fact hoping you would come in & give us some more detail as to just how you acheived this. Also if perhaps with the connections you had if you had by any chance had an original part tested as to what was there before anything was done.
As you said I have no idea from what temperature you quench to acheive this depth of case. All I have ever seen on the subject is that in order for a low carbon steel to absorb the carbon it has to be above its critical temperature & that to harden any steel has to be quenched from above that temp. As it absorbs the carbon & the case acquires a higher % the critical temp is lowered. Now I have read accounts that "Some" doing color casing drop the temp prior to quenching, which supposedly assists in prevention of warping. Note I did not say you did this, or actually even state it was an improper method. I simply asked the Question "If" this would in fact result in hardening of the entire case or if it would only give hardeness to a very superficial layer of it.
I still want to know the answer to that. As the process adds the carbon from exposure to its surface it makes sense to me that the deeper into the case you go the lower the % of carbon will be.
I am thorughly convinced that re-casing a gun frame is a job that needs to be done "Right" or not done at all. Nota Bene (Note Well) I am not accusing yours of not being Right.
From your posts on this I felt you could likely answer some of my concerns, but rather than attemt it you just chose to make a personal attack on me. I Pounced Back, for this I do appoligize. Perhaps we can still act like men & have a meaningful discussion on this from which All can benefit.
