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! :)
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!
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!
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.
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 TH-cam) and they are presented in a more logical fashion than they are on the THATLAZYMACHINIST TH-cam page. TH-cam 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.
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
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.
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! 😁
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.
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.
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
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
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
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.
Thank you very much Marc! I am just a hobbyist home machinist and I truly appreciate the wealth of information that you share with us. I have boxes and shelves of small unknown steel pieces that I have collected over the years from my local scrape yard. After this lesson I will now be able to better identify them! I have never seen the glass ball used before, that is an amazing demonstration!
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. 🇦🇺🤜🏼🤛🏼😎🍀☮️☮️☮️☮️
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 :-)
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
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
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
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
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!!!
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.
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.
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.
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.
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.
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.
A multimeter is a useful tool for figuring out what kind of metal you're dealing with. Different metals have different voltage potentials with respect to a reference electrode.
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
Hi Randerz, it would be difficult, as you may know or may have noticed from certain errors I make, I am French Canadian. For some time now I have been making my videos in French and in English. Since my videos are unscripted, I film a scene in one language and then redo the scene in the other before I forget what I said! (I am not getting any younger). French people like many Mediterranean cultureS speak a lot with their hands. I have noticed that when I film the French first, the English version has a lot more (and sometimes very awkward) hand movements. I always film in English first now and it helps a little. Thanks for watching my videos, it's all in good fun! Marc L'Ecuyer THATLAZYMACHINIST.COM
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
No sparks, file cuts well, gummed up grinder, stinks familiarly when ground, bouncing ball stuck; magnet? Extensive visual revealed coarse grain almost resembling hairlike fibers. I marked the unknown sample with my stamping kit (which is missing the letter t) with certainty as ca -shi . It seems to have a shelf life though :(. Great info, thanks Marc!
Hi Costa, the song is one of my brothers funny creations. Here is a link to the full version. th-cam.com/video/cizbhtbmv5I/w-d-xo.htmlIt 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
I must say Marc you are a very knowledgeable person and a very good teacher, but you need to do something about the acoustics in your cinder block shop. Overdub it or something.
Leonard Legg Hi Leonard, I am working on the sound, the recent videos are better? I think? But again after a lifetime in noisy shops my expectations are quite low. Thanks for watching, marc L'Ecuyer
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?
After watching this video I think I finally get it.......MARK MY BLOODY STEEL. Great vid as always
LOLLLLLLLLLLLL😂😂😂😂😅😅😅😅😅😅
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! :)

Marc I am a machinist of over 30 years so you should feel proud with my two thumbs up. Good job
Thanks Tommy, more to come. Marc L'Ecuyer
logically and clearly presented, good teacher
You are an amazing teacher. My mind never wandered off while watching this vid.
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

Excellent information presented by a professional. I'm absorbing like a sponge.
His knowledge is incredible ! Thank You for sharing. Much appreciated...
This channel is pure gold
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! 😁
You teach so well
And have such a depth of knowledge
Thank you for sharing and teaching
One of the most informative channels
I can't believe this video has so few comments.
That was a very informative demonstration. Thank you.
These videos makes all other on the subject superfluous.
Excellent video Marc, thank you for sharing your vast knowledge with us.
Im in a process of being a machinist this helps me a lot thank you sir!
,,even the video is older,it helps a lot to me thank you sir,
Thanks so much, Marc, I learned a lot from this video. Much appreciated.
All your videos are so well explained ..and a wealth of information. It has been a great review from studies way back ..
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.
Thanks Don! Marc.
Systematic info and clear explaination. Thanks!
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.
Thankyou Thankyou Thankyou!!! This clears up so many questions I’ve been curious about being an amateur welder (tig). Great vid!
Thank you so much for teaching this lesson!
Excellant video and methods that I will apply in my work.
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
Marc, I physically shrieked (.with) you at the same time. I can't say enough good about your vids. Extremely well explained.
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
Thank you so much for this informative video.

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

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

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
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.
Old video - but worth a thank you!. the two different file grades is a nice touch, didn't know that!
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
I truly appreciate your video you did a great job.
Thanks Sir
Thanks for that massive info.
Une vidéo de qualité supérieure! Bravo y merci beaucoup...
thank you very much,now i have idea what steel to make a tool holder,thanks again cherssss.
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

Thank you!!!
THIS. WAS. EXCELLENT! Thank you.
Thanks Jeff! It's nice to know that my little retirement project is helping. Marc
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.
very informative!!......thanks.

You can weld aluminum with 4043 or 5356 and you can weld cast iron with expensive specialty nickel electrodes
Thank you I had the Jedi knight knowledge moment I believe.
Extremely helpful!
Thanks this is a test I will be using.
I never get used to that utterly ludicris theme song of yours :D
Good vid, man. Thanks.
Very good video. Thanks for taking the time and making it.. Regards from brazil
thank you very much for this video. Very important for me.
Great teaching! Thanks!
Very informative videos! Well presented. Minus the weird intro and outro :P

Great info - thanks
great explanation ... thanks alot
Hold on, I'm not supposed to go into debt while doing this? Now you tell me.
Jon Miller: NOW they tell me!
I like what this video is aboot.
thank u sir very use full for me
Gran video, lástima que no esté en castellano! 10años ya desde su publicación? Será de mucha utilidad por mucho tiempo!

NOBOX7 Thanks NOBOX7! mARC
Just came across your channel, really good video.
No sparks, file cuts well, gummed up grinder, stinks familiarly when ground, bouncing ball stuck; magnet? Extensive visual revealed coarse grain almost resembling hairlike fibers. I marked the unknown sample with my stamping kit (which is missing the letter t) with certainty as ca -shi . It seems to have a shelf life though :(. Great info, thanks Marc!
Needless to say, how perfectly you teach. But I wonder if the file can withstand a metal-test on cement carbide without getting damaged.
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
Love the song!
Hi Costa, the song is one of my brothers funny creations. Here is a link to the full version. th-cam.com/video/cizbhtbmv5I/w-d-xo.htmlIt 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
Can't wait to use a piece of PVC pipe and marble to check different alloys.
You can harded mild steel some with water. Not as much as tool steel but improve it.
Nice video
thanks for the lesson
I must say Marc you are a very knowledgeable person and a very good teacher, but you need to do something about the acoustics in your cinder block shop. Overdub it or something.
Leonard Legg Hi Leonard, I am working on the sound, the recent videos are better? I think? But again after a lifetime in noisy shops my expectations are quite low. Thanks for watching, marc L'Ecuyer
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?
Sure! It will work just fine with a hardened steel ball! Thanks for watching and for taking the time to write, Marc
Thanks 😎
Some types of stainless steel are magnetic, like the silverware in your kitchen.
"haerd". Have you been to ram ranch also? great vid bud :)
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?
Great n
excusez moi et merci beaucoup et bonne continuation
