Certanly Oscar would share his article with Mal, but excuse me this article doesn't belong to me, it belongs to DGJ and probably to Oscar' successors. Why do you want me to break the law? If you have this DGJ volume, make a copy and send it to Mal. If one of my close friends ask me to do it, I will, cause this is my friend and I can't say no.
Sorry Mal, nothing personal.

I got the same problems with my articles here. One Ukrainian journal for men "XXL" stole my article about damascus and published it without my permission. Dozens of different Russian speaking resourses posted my article about waterfowl calls without link to origin etc.

Geno, I have no problems with your views, and respect your position.

JayCee, Thanks for the clarification and PM. No worries, I'm sorry I misunderstood; the red mist was rising.

For others who responded via PM and email, again, thank you for the help plus the descriptive comments, all of which I agree with.

FWIW I had an amusing and friendly correspondence with the late Dr Gaddy concerning the interpretation of archaic chemical terminology and it's currency within the modern Birmingham trade. I worked in the retail section of an outfit that supplied the old Gun Quarter with it's chemical and polishing bits and bobs prior to taking my degree.

Excuse me Gentlemen, but am I to understand that a process developed by our forefathers is not to be passed on by mentoring anymore unless we pay our dues?
I am very sure that Oscar would turn in his grave if he was to hear that a fellow artisan was being impeded through lack of co-operation.
How sad that the skill of colour hardening has to be relearned by trial and error, not to mention considerable expense. Because someone who has the knowledge is not prepared to pass it on.
Especially when the OP mentioned that he has paid his dues and bought but unfortunately misplaced his original copy. Where would we be if people had not passed their knowledge on to Oscar?

I have a set of DGJ from the beginning to now, slipcases, indices, some issues still in plastic wrap. I want to sell this set to someone who doesn't think that I am violating some copyright law by sharing this information for profit. Is there some difference between copying an article and selling a magazine with the article included.

A very informative sub forum on CC Hardening can be found here:-

http://www.marlin-collectors.com/forum/viewtopic.php?f=21&t=3732

It runs to 24 pages in length and is the most informative I have ever come across on the WWW. The thread started by JimD goes along the difficult path of learning the art and he shows his methods and results along the way. It is a MUST READ for anyone wanting to know how CCH is accomplished.

Whilst I have the greatest respect for Dr.Oscar Gaddy it is also with respect that I say he got some things wrong. Hardness and magnificent colours can be obtained at lower temperatures than Gaddy used and without the warpage usually encountered. Certainly a little does occur, but very little. Quenching is a vital part of the colouring process and to get it even colours on both sides of a part required more than just a quick dunk in the water barrel. Even that is explored, covered and methods developed for ensuring consistancy.

Don't take my word for it, read the whole thread.

Hello Harry,

Great thread. Thanks for finding and sharing it.
Jim D is an example of generosity.

JC

Well done Harry Eales for your informative post.
Now someone please give Eugene the information he requires as he becomes unbearable when he sulks.I can't see what the problem is with sharing information. Annoyingly the information Oscar gleaned was probably given freely and hopefully for us all to benefit from by sharing.

Also plenty of examples of chaps whining and rationalising why some one owes them something,for nothing. I wonder if they would feel same if they were in publishing and owned the intellectual property? Past issues of the Double journal are avilable from publisher at nominal cost. Mates, you can get one for the cost of an hour at the pub.

Having read the Marlin post at length, it seems that CCH is easiest (read successful) on the older low carbon steels. Turnbull and others evidently have found a way to color the more modern, higher carbon, and harder steels...or have they? I wonder if the CCH process on an action designed for high chamber pressures is actually compromised because the necessary tempering temps required to restore the original strength would also remove the case colors? In other words is a pretty action actually weakened in terms of modern steels when case colored by any heat induced method. Or do they use cyanide or something else to achieve the appearance of CCH only. Many questions and not much chance Turnbull or others are going to cough up any secrets... Steve

The surface of mild steel becomes high carbon steel during CCH process and if you do not cross the Rubicon (criticasl point) before quenching, you won't get hard steel on surface, just colors only. The CCH process at lower temperatures is cosmetic one. Ed1 comes to mind.
