Chris from Australia (youtube channel Clickspring) has an excellent short video on case hardening using only materials that would have been available in Ancient Greece. It is part of his series on recreating the Antikythera Mechanism. Here's the title of the video: Antikythera Fragment #4 - Ancient Tool Technology - The First Hardened Steel

What an amazing and informative video. Makes me miss my Grandfather on my mother's side. He was a woodworker and made jewelry cabinets and some fancy furniture. Had so many tools and tricks. He worked for Martin Aircraft for years and during WW2. He developed dementia and died when I was 14 in 1984. Would have loved to work with him and learn his craft. Keep up the good work. I enjoyed everything you talked about. No need to apologize.

[@mrpete222]

Sounds like a wonderful grandfather

[@ravenfn831]

@@mrpete222 that generation, at least with my grandparents, were gritty. They were very careful with money as they had both probably been hungry from time to time. I think my Grandfather made wooden jigs for Martin for them to make the American bomber (b-25, maybe?) Anyway, have a great day.

[@dougmacqueen1679]

A somewhat similar method of hardening the outer surface cast iron has been used by the Corliss Safe Co. Since cast naturally has a very high level of carbon in the mix, none has to be added. It had to do with how the iron was cooled. Instead of pouring the cast into a sand mold, steel molds were used. Well I think they were steel, but for sure they were metal, which caused the metal to cool very quickly. This caused the outer surface to be quite hard to prevent drilling, with the drills available at the time in the 1870's. The resulting metal was called white cast iron.

[@123232ism]

I love the fact that you are not afraid to get a little oil on your hands. I am from the days where you checked the oil in your car engine by wiping the dipstick between thumb and forefinger. If you couldn't see your finger, you changed the oil; if you could, run her another couple thousand. Never had an issue, ever. Sorry if I seem cantankerous, but I am.

Excellent video,Mr. Pete.I´ll like to mention two things.First thing is about quenching deformation because of the heat shock.Second thing is that as compared to other case hardening methodes that I´ve seen ,the piece plus the hardening mixture,both go into the oven in one take and after heated they go to quenching .There is a video in Antiquitera(not sure the spelling ) that tells you how they did it several thousands of years ago.Thank you.

MrPete, Lyle, your videos are the only one on the internet that describes the processes so well that I can actually replicate them in my home shop: A shop I do not believe would have grown or evolved into such a useful space, or with the Journeyman skilled carbon based life form in it, without you! Please keep making long videos with actual usefulness. I am sorry if they do not make you rich, but Lord as my witness you enrich the world. Have you considered an Anthology? A USB drive with all your videos on it is something I would pay for! My alternative is to pay a software company to buy their product and use it to download all your content. Paying you is a much more attractive idea. a PS to a long post - I love my T shirts from you!!!

[@MDAdams72668]

Funny how now man students graduate high school (and often college) without basic knowledge of how metal and wood can(and cannot) be used to create things. I was in the last class(in my high school) that even had "shop" classes I learned more in my metals, woodworking, and electronics classes that I still use today than many people will ever know about these "basics" So sad. Thanks for being here to help educate our youth.

[@randyhertzberg7549]

I was one of those who took , literally EVERY shop class available (I was just the right age that could have been in your class) Wish you taught in Kankakee. I later went on to a community college to get more welding and metallurgy , YUP , that Tempil diagram is still in my reference library. OH , by the way I'm still welding , 49 years now . I love the way you teach and explain things , even though some of it is review for me. Such a shame that young people don't have the educational opportunities that I (we) had.

[@mrpete222]

Thank you for watching and commenting. Yes, the decline in vocational education is very sad

[@clairehoy5037]

The method you show is really a combination of dip and pack casehardening where the item is enclosed in an airtight box.

[@ohmbug10]

I too like that finish. My HS shop teacher asked me to carburize mild steel in used motor oil. It was what was available but worked...and yes the other kids were mesmerized by the smoke and fire.

[@johnyoung7794]

About a thousand years ago while attending a technical collage I took 2 semesters of metallurgy. We had an "always hot" caldron of cyanide salts at our disposal. when our mild steel high school projects reached cheery red and quenched in a salt brine a very pleasing color case hardened finish was achieved. Mauser military rifle actions were case hardened.

[@briannemec9214]

In shop class,, 1961, I made a scroll bender. We case hardened in a small gas fired "box". Cherry red and into the carbon stuff and back into the gas fired box. Then the water dip. The box was also used to heat a large copper soldering iron. Used that iron to solder parts we made out of tin cans. Parts were made using sheet metal layouts techniques. I made a water sprinkling can. "In the old days" we were taught how to use our hands and minds more. We had auto shop, wood shop, electrical shop and metal shop. I even spent a week in Home Ec. made a great cinnamon roll cake.

[@allanmartyr2961]

Not to take anything away from Mr Pete. I have learnt a lot from your videos and using in my little workshop at home here in Australia. Click spring has a video on case hardening files he’s made himself. And also has a recipe for the powder he used. Clickspring the First Hardened Steel. Thought it might be interesting. Love your work Mr Pete. Keep it up.

[@mrpete222]

Seen it

[@lathammarx1458]

Great video on heat treating, Just like the shopkids, people love fire and explosions.! The process can be used to make cutting tools. But you have to harden multiple times to get the case deep and of course, pregrind the tool so that only light hoaning is required to touch up the edge. Of course, when you regrind the tool is toast.

[@ExStaticBass]

I would love to see more videos about hardening. It's something I've tried to figure out on my own to limited success but never really had a reason to study. Thanks for taking the time to show us this.

[@awizardalso]

I learned how to heat treat on another video on KZbin. I use a small charcoal grill mounted on a V-shaped stack of bricks and use a fan to force air up through the bottom vent in the grill. I heat the metal parts in the charcoal to red hot, then quench them in used motor oil that turns them black and rust proofs them. Then put them in the oven at 250 degrees for 1/2 hour. and let them cool off.

[@Phil659]

More heat treating please! excellent video as always

[@larryleek2030]

I have about half of a half pound can of Kasenit that I used when I was doing gunsmithing some years back. Haven't had much need for it lately, though and don't know when I might again, but I have it anyway. It always worked well for me.

[@tobyw9573]

Beautiful swivel jaws! I'll have to watch the video where you made that. This Old Tony has a beautiful machinist vice where the usually cast-in end of the vice is a square piece that swivels and has 4 different purposed sides. Interesting as well, since you could make the vice from stock of perhaps half the thickness of the one-pice body.

[@jamesbornman5556]

One of my favorite videos

[@mrpete222]

Thanks

[@scotthaddad563]

Mr. Pete, thanks for the video! I have done a little research of my own on this subject and a modern (home brew) method is to use a mixture of bone and wood charcoal and some recipes add charred leather. If done without much exposure to air you can get some colors as well.

[@mrpete222]

👍

[@almorassi]

You can place the piece inside a larger box, filled with coal. The box must be closed to maintain the internal atmosphere with a good level of carbon. The ideal is to leave it in the oven for at least two hours, to form a layer about 0.3 mm thick. After half an hour, the layer is no more than 0.05 mm.

[@dugwthree]

I did that in high school. Made a 2 jaw puller. Have it and use on occasion 50 years later

There are some recipes for casements using flour water and table salt. The item is baked from cold through soak, and then quenched while in the casing compound.

Excellent series Mr Pete, I thoroughly enjoyed them all, from making the jars to surface hardening Please make more Sir

[@bobvines00]

Lyle, I've read of case hardening to different depths by varying the times of the treatment -- longer times for a deeper hardened layer. Can Kasenit (or equal) be used like this or do you really have to make multiple runs with Kasenit? Or is the process I tried to describe above depend on a different case hardening "material"/powder/potion? Here's my vote for a series on heat treating, especially on what can be done in the home workshop, along with using a small heat treating oven like yours or the other ones that are now showing up on KZbin (I can't think of their name off the top of my head right now).

[@dreadnaught2707]

I once read in a model engineering magazine that it was possible to do case hardening (at least to some extent) by using sugar. Sugar has a high carbon content that transfers into the first few microns of the hot steel. I've never tried it myself though.

[@bjen2005]

Definitely enjoyed Part 1 and Part 2. I would like to see a video on annealing and heat treating. There are so many things that it can be used for. Have you ever used boiled linseed oil or shellac on your metal parts to keep them from rusting? I know a lot of older woodworkers used nothing but linseed on their tools.

[@mrpete222]

I was using shellac only minutes ago, in fact there is still some on my fingers. But I was using it up on my wooden patterns, never use it on metal.

[@ryanpelz6964]

Would love to see more on heat treating. Thanks for sharing all the knowledge.

[@michaelwright4165]

Thank you! I enjoyed this session; I've been case-hardening iron and soft steel for decades, but there's always something more to learn. May I please pick up on one point? You say that case-hardening isn't suitable for a cutting tool, but I have often used it for one-off, special-purpose tools such as form tools. For instance, a cutter can be made out of mild steel if that's all you have to hand, and after a good soak in the case-hardening compound the skin is quite thick enough to allow it to be polished and even honed.

[@mrpete222]

Good point

[@gregwitkamp5583]

Really like your videos , I had wood, metal, and auto shop in High School in the mid to late 60’s with great teachers . its really a shame that they have deleted that for many years. just in the last few years there starting to bring it back.

[@mrpete222]

👍

[@PaulSteMarie]

This has been one of your best series ever! It's a topic near and dear to my heart, and the more you want to do on it, the more I'll watch. So, the reason that I'm really interested in this entire process is that it provides a functional finish on a part, using not-too-horribly dangerous reagents and you can get beautiful parts this way. Actual black oxide finishes are way too dangerous to attempt in a home shop; even the medium temperature processes are still running very hot lye solutions. The cold blue finishes just don't seem to be very effective, and I'm a bit concerned about the selenium in them. The classic case hardened finishes using charcoal and heat seen like a total win for the home shop, with parkerizing perhaps a second. The thing I really want to try is color case hardening with charcoal, which I believe you do pretty much the same way as this only seal it up in an stainless full envelope.

[@mrpete222]

I am so glad you liked the video. And yes, it is a very interesting process

[@leebrown3263]

In 1978 I started a 2 yr associate degree program at Rogue community college in southwestern Oregon. One of the first classes we had was on heat treatment. Used lots of Kasenite since then. We were told though I admit I never tried it that in a pinch finely crushed charcoal briquettes used in place of would would do the same thing as Kasenite and some of the other available compounds. Still have the text for that class though I'd have to look to find. I heat treatd a lot of gean G3 battle rifle parts out of air hardening stainless steel. They were then shipped to El Salvador. Politics huh! Can you imagine a community college involved in something like that today.

I enjoyed these two videos and I still have my threequarters-full 1lb tin of Kasenit, though I haven't used it in a long time. I never had a furnace but I was only case-hardening small parts so I used the dipping method with a propane torch. Sometimes just for sake of the appearance, rather than durability. And, yes, I too found pages 648, 684, and the disappointment of p427. Still, at least now I know how to colour billiard balls red, if I ever need to (p428).
