RECOGNIZING STEEL ALLOYS, HOME TESTS & TRICKS THAT REQUIRE NO SPECIALIZED EQUIPMENT, MARC LECUYER

[@69hytek]

After watching this video I think I finally get it.......MARK MY BLOODY STEEL. Great vid as always

[@julian089]

LOLLLLLLLLLLLL😂😂😂😂😅😅😅😅😅😅

[@georgegalindo8616]

Thank you for being one of the people that helps people like me like a real teacher should. I made a knife the other day and i wanted to know how hard it is and I learned that since my file doesn't leave a mark on it... it is hardened enough to be used for the purpose i designed the blade for! :)

[@jonarbuckle1560]

i never cease to marvel at how talented a teacher you are. It really is quite a rare gift

[@markfergerson2145]

Tripped over this video accidentally. Subscribed. Now I have to go through your whole list of videos.

[@THATLAZYMACHINIST]

Hi Mark! If you have a few moments, check out my website THATLAZYMACHINIST.COM . All of my videos are on the site (the site is really just a bunch of links to KZbin) and they are presented in a more logical fashion than they are on the THATLAZYMACHINIST KZbin page. KZbin searches tend to favor popular videos and well some times the least interesting ones are the most important (my four machine shop safety videos are a good example). Have fun and be safe! Marc.

[@icyburger]

You are an amazing teacher. My mind never wandered off while watching this vid.

[@THATLAZYMACHINIST]

When I was teaching I was always considered to be a specialist in putting students to sleep. I guess that you must be Immune to my powers!!! Thanks for watching, Marc

[@lsubslimed]

I'm sure it helps a bit to be very interested in the subject that's being taught. I love learning 'bout steel so I was able to follow along very nicely 😉👌. Very informative vid btw! I picked up a couple new tricks that I never knew about.

[@ladykay8]

I come from the woodworking world and I've always been a little leery of getting into steel, because you have no idea what is what. This is going to be enormously helpful, thank you so much!

[@dolata000]

logically and clearly presented, good teacher

[@WXUZT]

His knowledge is incredible ! Thank You for sharing. Much appreciated...

[@frikkied2638]

This channel is pure gold

[@michaelmacdowall4228]

I am a 24 yo small engine Mechanic who works with prefabricated parts with defined roles out of (from my perspective) unknown materials. Most pieces have already been engineered for defined roles and under normal use perform optimally. However without information such as part numbers or when a part has reached the end of its service life I often need to have an accurate view of what the material is. Thank you very much for your practical wisdom and the amount of time and effort you put into this video it is greatly appreciated and I look forward to exploring your channel further. Thank you again for your time!

[@ciprianokritzinger3636]

Excellent information presented by a professional. I'm absorbing like a sponge.

[@Bayhunter2011]

Excellent video Marc, thank you for sharing your vast knowledge with us.

[@theisgood0]

THANKS SO MUCH I'm 21 and an apprentice machinist so this helped me a lot not many kids in my generation take machining its an important trade to keep around.

[@tommydarchbald4893]

Marc I am a machinist of over 30 years so you should feel proud with my two thumbs up. Good job

[@THATLAZYMACHINIST]

Thanks Tommy, more to come. Marc L'Ecuyer

[@michaeltyler4048]

You teach so well And have such a depth of knowledge Thank you for sharing and teaching One of the most informative channels

[@sandtown2661]

Great person and teacher

[@curbyweaver4606]

Thanks so much, Marc, I learned a lot from this video. Much appreciated.

[@girliedog]

Excellant video and methods that I will apply in my work.

[@zigydk]

These videos makes all other on the subject superfluous.

[@nguyenminhha9821]

Systematic info and clear explaination. Thanks!

[@richardvermeulen3123]

Thank you so much for teaching this lesson!

[@beltfed4624]

A very practical instructor, keeping it old-school. I would have loved to had him as my teacher, so many years ago. I had to learn a lot on my own, the internet was still science fiction, LOL! 😁

[@snap-off5383]

5:33 This was my science project as a junior in high school. Had some 4130 from dad's race chassis mod, awesome sparks.

[@arashkhanegol]

Thank you so much for this informative video.

[@jamesdepaul3410]

Excellent information, thank you

[@markocomen1550]

Thanks for that massive info.

[@ryanads29]

,,even the video is older,it helps a lot to me thank you sir,

[@neo3768]

Thank you very much..I'm so happy finding this

[@das250250]

All your videos are so well explained ..and a wealth of information. It has been a great review from studies way back ..

[@dylangammons6596]

Extremely helpful!

[@MrAllan9]

That was very well done, and so informative. Thank you.

[@passenger6735]

I can't believe this video has so few comments. That was a very informative demonstration. Thank you.

[@ofwdad5893]

Im in a process of being a machinist this helps me a lot thank you sir!

[@BasementShopGuy]

Marc, I physically shrieked (.with) you at the same time. I can't say enough good about your vids. Extremely well explained.

[@THATLAZYMACHINIST]

Thanks Basement (I'm guessing Shop Guy is your family name) for your kind words. The videos are something I do for fun and it is nice to now that they are appreciated. Thanks for taking the time to write. the next video is going to be a real barn burner. Blueprint reading part two! Not exactly exiting, but nice to know. Marc L'Ecuyer

[@dalskiBo]

Great info - thanks

[@MrRatkilr]

I love this dude... no homo.... lol been machining for years never heard of the bounce test with a marble for testing hardness. Pretty slick and easy an cheap. Learn something new everyday.

[@tinylockpicksinc.1758]

When I first started watching these videos that intro music had me thinking oh boy here we go some goofball but I got to say these are some fantastic videos you set up here Very very well done

[@johnforrester2106]

Thankyou Thankyou Thankyou!!! This clears up so many questions I’ve been curious about being an amateur welder (tig). Great vid!

[@emafex]

Nice video

[@donoday8101]

Thank you for taking the time to help us understand the process of testing steels. As a beginner Smith I am still learning about steels. Great video I learned something new today.

[@THATLAZYMACHINIST]

Thanks Don! Marc.

[@jeffchapman8992]

THIS. WAS. EXCELLENT! Thank you.

[@THATLAZYMACHINIST]

Thanks Jeff! It's nice to know that my little retirement project is helping. Marc

[@SandeepSharma-bg6bt]

very informative!!......thanks.

[@THATLAZYMACHINIST]

+Sonu Sharma Thanks for watching Sonu! Marc

[@stevesloan6775]

That’s still a great video, and the song at the end carries so much passion. I learned a lot for your great content and it set me straight whilst welding 4041 chromium, manganese and gallium alloy steel. I really loved the judging steel composition through listen to the sound. Heck I so should fabricate a tool to drop chrome plated ball bearings. Thank heaps from your efforts to teach people. 🇦🇺🤜🏼🤛🏼😎🍀☮️☮️☮️☮️

[@jackdawg4579]

Old video - but worth a thank you!. the two different file grades is a nice touch, didn't know that!

[@THATLAZYMACHINIST]

Thanks Jack, as time goes by I tend to enjoy more and more old things. As an example I can categorically state that I have no interest what so ever in Pokemons, I don't know what they are and I don't care and I am smart enough to know that my phone isn't smart. Thanks for watching and for a great comment, Marc

[@Pro1er]

Thank you, this was an *excellent* presentation! I just wish that the sound was better.

[@heliobnm]

This video was very useful. You are very clear when you teach. In addition, you are amazing for sharing your knowledge in this area. I think we need more people like you. Thank you from Argentina. P / D: Sorry for my English

[@THATLAZYMACHINIST]

Your English is just as good as mine, it is a second language for both of us. Thanks for watching and for taking the time to write, it is nice to know that my videos are useful. Marc

[@johnjude2685]

Thanks this is a test I will be using.

[@Wroom90]

Great teaching! Thanks!

[@mtrltoolman]

Very helpful and informative video, thanks.

Very very helpful !

[@axolpolly3366]

thank you very much,now i have idea what steel to make a tool holder,thanks again cherssss.

[@kevinfaulkner8801]

Thanks for the info that I have not gotten from any other sorce.

[@THATLAZYMACHINIST]

It's all about having fun and keeping things simple. Thanks for taking the time to write and for watching my videos, Marc

[@soldoroja3915]

As a beginner, It would be great, while talking there is a video popping what you mean. And zoom to that steel you are referring.

[@steelddd]

Very informative videos! Well presented. Minus the weird intro and outro :P

[@Ujeb08]

Marc, thanks for the informative video. It was a good refresher for me.I particularly enjoyed the spark testing section. Many years ago I started working for an engineering department where they were performing fatigue testing on specimens. Things were not making any sense to the professors because the specimens were failing at the wrong cycles. I was asked to take a look at the process . I suspected that the vendor was supplying us with faulty samples. so I set out to do some tests. I remembered spark testing was one way to identify carbon content of steel so I set up a grinder and camera. Sure enough the carbon content was much higher than expected. Your explanation was much more in depth - I was looking just at the amount of sprigs or branches in the sparks. Thanks again. Jeff

[@londiniumarmoury7037]

Just came across your channel, really good video.

[@costafortia6854]

Love the song!

[@THATLAZYMACHINIST]

Hi Costa, the song is one of my brothers funny creations. Here is a link to the full version. kzbin.info/www/bejne/mZrdk5uql9Kpa6sIt sounds better if you have a drink first, and yes my brother is a medical doctor. Thanks for watching and be safe!Marc THATLAZYMACHINIST.COM

[@CplNet]

Very good video. Thanks for taking the time and making it.. Regards from brazil

[@bobpowers6111]

[@manoharangss]

thank u sir very use full for me

[@dalemeyer8207]

Thanks 😎

[@JonHeckendorf]

I knew there had to be these kinds of tests to identify various materials without having to own or use expensive test equipment but I could not find this kind of information until Marc Lecuyer explained it. And, he explained it really well. Also, ID (mark) your material all up and down the material. Thank you, Marc.

[@THATLAZYMACHINIST]

Hi Jon! It's all for fun and I am glad that the video helped you on your way. Thanks for watching and for taking the time to write, Marc.

[@mitchdenner9743]

Just mark one end and cut from the other .

[@jensmelbye8781]

thank you very much for this video. Very important for me.

[@patrickroeill8746]

thanks for the lesson

[@DaveEtchells]

Super useful video, thanks! I’ve added it to my metalworking play list so I can refer back to it going forward. (Next step is I need to assemble a set of test samples to compare to each other :-)

[@mrfxm55]

Thank you I had the Jedi knight knowledge moment I believe.

[@kennethperry7160]

I like what this video is aboot.

[@mrbluenun]

Hi, And thank you so much for such a huge wealth of info in this video. I have never heard a lot of the thing you brought up about different steels. Thanks again. Take care mrbluenun

[@bigornafilmes]

Great n

[@ogreunderbridge5204]

I never get used to that utterly ludicris theme song of yours :D Good vid, man. Thanks.

[@pavlesapic3726]

Tnx Marc..this info is gold!

[@EnriqueZar16]

Excelent

[@NOBOX7]

amazing video , very informative, i will click your adds to help you generate revenue for your hard work, i know how much work goes on behind the scenes to make something like this come together

[@THATLAZYMACHINIST]

NOBOX7 Thanks NOBOX7! mARC

[@johnmisavich9680]

Excellent video it answered all my questions and a whole lot more. I am interested in not only machining as well as blacksmith work and i have most of the tools. the lathe i have is a Whacheon 21" x 80" D1-6 Lathe 12" 4-jaw Chuck, Steady rest, Coolant but am self taught having no prior training and have made some costly mistakes alot of broken cutters. But alot of fun learning and am now a subscribers thanks again.

[@RelentlessHomesteading]

Kinda puts it all together - thanks. I'd never seen the simple scleroscope, I like that, would be great for comparing two similar looking articles. Usually i've been just using visual, magnet, and file, and usually gets me all I need. Think I'll start a sample box with marked loose ends. I'm getting more into metalworking, looking to build a decent lathe and get my shop upgraded. Always lots of projects to be done here on RelentlessHomesteading, and I've got some interesting builds coming up so lots to learn. Appreciate the video. I subscribed and will be checking out more of your vids.

[@THATLAZYMACHINIST]

Thanks! Marc THATLAZYMACHINIST.COM

[@thebaron222]

For a newbie who walks into the offcuts section of the metal store looking for small pieces an incredibly informative video. Thanks very muchly! :)

[@davidbottomley8086]

good stuff !

[@THATLAZYMACHINIST]

Hi David! Maybe this video could help. I produced it some years ago. if it does not answer your questions, get back to me. Marc kzbin.info/www/bejne/sHS4oIR_pKimmrM

[@horkinyorkin]

thank you I learned some on this video. Can a ball bearing be used instead of a glass bead (marble?) to make the schlerescope tester?

[@THATLAZYMACHINIST]

Sure! It will work just fine with a hardened steel ball! Thanks for watching and for taking the time to write, Marc

[@TheMrFrugal]

Thank you for making this video. I wish I had taken machine shop in high school. (That was back in the Olde Days, when such practical courses were offered. I also wish I'd taken Business Typing - Who knew that computers were going to be rampant in the 21st century?). I instead opted for Drafting and Electrical, the latter which has served me quite well over the years. Drafting? The only thing I can say is that I learned isometric drawing. (And always have a decent eraser with you). My father, despite being illiterate, taught me automotive skills and "very" basic metallurgy, if you will, in his garage. Although, a couple of his pointers were wrong; "You can't weld cast iron or aluminum." You can, just not easily with a stick welder and the wrong welding rods.

[@RelentlessHomesteading]

Hi Frugal -- Wow sounds like my experience --- too busy with math/science classes to take shop. But took drafting, and to this day, yes it still helps in whipping out a drawing or iso. And went electrical eng. as you said. Similarly learned alot from my Dad whose father was a blacksmith, ...but some things to unlearn. I've kinda gone full circle. Was able to do all the analog, digital, and operating system designs I wanted, and now getting more into metal working; but I'm kinda into learning how to do everything project related -- such is the nature of Homesteading here at RelentlessHomesteading, I gotta shoot more of the metal work projects around here.

[@joshp6061]

You can weld aluminum with 4043 or 5356 and you can weld cast iron with expensive specialty nickel electrodes

[@abelferquiza1627]

Gran video, lástima que no esté en castellano! 10años ya desde su publicación? Será de mucha utilidad por mucho tiempo!

[@Pigi_102]

Hi, I've a question for you: you say , in video ( at 17.10 ) , that the structural iron is mild steel, and then you show ( at 18:20 ) a different look material that you call again mild steel. What's the difference ? Thanks Pierluigi ( and thanks for your videos )

[@THATLAZYMACHINIST]

Pierluigi Frullani Hi Pigi, mild steel is steel that contains low amounts of carbon that cannot be hardened by quenching. These steels come in many forms: #1: structural steel (I beams, angle iron, C channel) that is hot rolled (crusty exterior) #2: Bar stock, plate, sheet (either hot rolled or cold rolled) #3: and all of the above as alloy mild steels ( steels that contain other elements than Iron and carbon)(often acid washed so not scaly but with mat finish). So as you can see, there are a lot of different low carbon steels. I hope this helps, thanks for watching and for commenting, Marc L'Ecuyer

[@Pigi_102]

It helps a lot!!!! Thank you !

[@ravanarbabi140]

Needless to say, how perfectly you teach. But I wonder if the file can withstand a metal-test on cement carbide without getting damaged.

[@joshp6061]

It’ll completely dull the file, an easier test for carbide is density, it’ll be twice as heavy as a similar sized piece of steel

[@johnkiljan7441]

Impressive. Thanks for sharing. I've found about half of the stainless steel in my kitchen is attracted to a magnet. I've also wondered if random bits of metal I've come across were actually wrought iron or even cast iron.

[@gamasax]

Sorry about this joke Marc, but i feel you you will find it pretty good. "ODOR"! Thank you very much for sharing your experience with the world! Personally i learn a lot! Thank you!!!

[@pequodexpress]

I ordered some leatherworking knives from a knife maker. Two knives were supposed to be made of M2 steel and one was supposed to be made of M42 steel. I think the knife maker may have used different steels. I was expecting the M2 steel to be darker and heavier. Are there certain liquid chemicals I can use to determine which steels have been used?

[@husinbawafi8340]

thanks

[@mikerope5785]

"haerd". Have you been to ram ranch also? great vid bud :)

[@bigornafilmes]

Gerar 👌🏻

[@diamonddog257]

Great Upload : ....Is there any tuffer make of machines than GENERAL ?.......I'm Albertan, and our cabinet saws lasted Decades of shop classes...Scary.....the Americans like their Oliver and Monarch...but I think we have them beat.... What is your pick for Lathe ?......A gunsmith lathe is more precise..etc...plse rspd. thx: DS

[@THATLAZYMACHINIST]

Hi Diamonddog, I had the pleasure of spending a couple of weeks in Alberta two summers ago! Edmonton, jasper, Calgary and everything in between. What a beautiful place! I have never met a machine tool that I didn't like, but I do like general quite a lot. Sturdy, tough and long lasting but at the risk of starting a debate, if I could get my dream machines (the ones I could never afford) I would choose a Hardinge lathe, a Deckle mill, a DoAll bansaw and a General drill press and pedestal grinder. Thanks for watching, Marc L'Ecuyer

[@diamonddog257]

THATLAZYMACHINIST ...Thanks L-M.....I've been snooping out the makes you listed....Deckle, Hardinge, Monarch.....etc. have gone to industrial production formats.....and hate to admit it, but Grizzly makes a good Gunsmith Lathe...a bit more precision and versatility...but how do you get it into this country??....DS

[@intjonmiller]

Hold on, I'm not supposed to go into debt while doing this? Now you tell me.

[@markproulx1472]

Jon Miller: NOW they tell me!

[@NOBOX7]

this song rocks

[@ironmaidyn]

Hi, I have a beer barrel and what to determine if it is stainless steel or aluminum, what is the best method? Thanks

[@joshp6061]

Steel will be far heavier and will likely be slightly attract a magnet. The aluminum will also be much softer

[@brentchalmers1436]

Marc, is there a home test to differentiate 304 and 316 stainless?

[@gilbertbrewer269]

brent chalmers I think the higher the number is better stainless some of the low number a magnet will stick to slightly. 316 is a food grade

[@joshp6061]

Those alloys are not very easy to differentiate. The only difference is 316 has slightly more nickel and molybdenum. It’ll be more corrosion resistant and tougher. Without pricey equipment there’s no good test for it

[@richardsager842]

No way, your'e not reading off of cue cards. That's so much information to just be able to pull out of your back pocket. If you're not cueing it up, I'm that much more impressed.

[@ironDsteele]

What would happen if you tried to harden carbide? Can you anneal it?

[@THATLAZYMACHINIST]

+Universal Steele Hi Universal! Carbide is a ceramic material and is naturally hard, and it can't be made harder or annealed. I hope this helps, Marc

[@ironDsteele]

It does, Thank you!

[@GoldenSim27]

Super le truc de la bille de verre , moi mon meilleur truc a la maison c'est avec un grinder et cutting wheel , plus c'est dur a couper plus c'est haut en carbon , si ca ''colle'' sur le disc , c'est du stainless ou un aliage mou . un peut comme le truc de la lime

[@idacow8237]

Hi Mark, I'm Mike, I'm Mike, and I'm currently enrolled in the provincial instructor's diploma program in Vancouver and I was wondering if I may use your videos as a teaching tool for my practicum? I find them very informative and relevant to my endevour in becoming a welding instructor

[@THATLAZYMACHINIST]

Ida cow No problem Ida, it's all about sharing and getting people interested in the trade. So I say to you and to everyone, use my videos as needed or as you see fit, as long as it is not for profit (no one has to pay to watch) ((I know the teacher is getting paid and that's OK)). Thanks for watching, Marc L'Ecuyer

[@idacow8237]

I'm just getting my PID now, this is just for a practice course.. thanks
