Thanks so much for the discussion of forging versus directly turning. Very educational.
Thanks!
@@torbjornahman It's very nice to hear you in general
@@torbjornahman any explanations of your work process are much appreciated. 😊
@@torbjornahman And smoothing those sharp corners! If everything is perfect, that's the place where things go wrong first. Very wonderful analogy to the wood. Steel is not that simple as many people thinks :)
Great video! I enjoyed the explanation. Thank you for adding the audio. I hope you can add it in future videos.👍
The flow of the grain to give strength to a bolt head works much then same way. My grandfather (Birger Waldemar "BW" Lindquist) had some patents for the die shapes needed to form the grain properly for cold-heading bolts. He went on to found Ring Screw Works to manufacture bolts and screws using this technique. He began as a blacksmith's apprentice in Sweden in the late 1800s before coming to the US in 1905 at age 20.
Wow, that's a cool story! Yes, much the same principle!
Some specialized bolts in aircraft engines have a more pronounced fillet between the transition from bolt head to shank, and require specific washers with a beveled hole to match the fillet. Use the wrong washer, or the right washer upside down, and you could easily have a failure of the bolt.
Dear Torbjørn - today I did my second ever forging - made a small hole in the garden with fire proof bricks and used coal and charcoal and a DeWalt blower with an old length of tube, bought a length of 16mm plain steel and made a cats foot bench dog! And it worked! Thank you so much!
Perfect! A very good start, and you're over that initial threshold that many struggle with - just do it!
After seeing what the application of the tool you forged was for, it makes perfect sense to go for maximum strength. Tools that last a lifetime are hard to come by, the cheap ones that last a year are just a waste of time and money. Thanks for doing it right all the time, your work never ceases to impress me, have a great day!
May the forge be with you Torbjörn, always.
Yes. It is.
I very much enjoy these last few videos forging tools for workers and artisans. The engineering discussion was wonderful as well!
Cool, thanks
Thunder Bear has done it again. Great job!
I always get such joy whenever I see your videos. I admire your craftsmanship
Thank you very much!
@@torbjornahman craftsmanship and video editing.
that short and simple answer, answered everything. I've thought that for some time 'why not just machine it?' :D now I know. this channel is awesome.
*- Thank you for the metallurgy tutorial, Torbjörn.*
*- I did not know that extruded metal produced grain lines and forging bent those lines to hammered shape...most informative and detailed practicum in inorganic physical chemistry physics.*
Thank you for the lesson! I think you’re a good speaker. Your explanation of why forged parts are stronger is exactly the same way my great uncle (who helped build the Gemini capsule) explained it.
Manipulating the grain structure not only improves strength but dramatically improves fatigue resistance and fracture toughness. Nicely done, sir.
I have to say I really like hearing you speak and explain things to us.
Cool to see surveyors in the vid having been a land surveyor for the past 13 years myself!
Cool!
Fun to see old ways making parts for new tools.
You would be surprised to know how many parts that are still forged today!
@@torbjornahman There are many, but not made by hand like this!
The little hollar when the powerhammer struck the center by accident, i felt that on a personal level 😂
Love the talking and explaining In this video 🙏
Tools made in Sweden are well made. You just proved the point. 👍😊 Great video. Thanks for sharing.
I think all of your reasons for forging vs. machining are great, the most important one is the third.
I can't say that I am surprised the original one broke, given the sharp stress concentrations you pointed out. A long time ago someone asked me to fix a kickstart shaft off a Harley Davidson, it had sheared exactly where you would expect at the sharp edge transition where they had ground a driving square on the shaft. I couldn't fix it of course. More surprising was the bad design, engineers have known about stress concentration for the best part of a hundred years.
I really like your vids when you speak and explain your work, your English is great!
I love his drafting table.
It's a bit low and has a odd shape....
Another smile put on my face by Torbjorn. Yes he is the best !!👍👍👍. JC🌵
I am very impressed by the precision of your forging. Though that piece of metal was beaten into shape by tons of force, it barely needed any shaping on the lathe to reach the final form. The only thing I missed was you adding your touchmark to this piece of industrial art!
Sometimes that touch mark will create stress risers of its own, so it's understandable why he didn't add it.
Nicely done sir!
The concentricity of that forged part is very impressive and testament to your skills!
I use a rod driver often and thought that you made an error removing the hex shaped shaft. Glad I was wrong! Making a tool that gets a lot of use is very rewarding. Great job⚒
It is much more fun to forge is the reason for this channel! Thanks for the explanation!
Once again you have shown what a highly skilled “metal worker” you are, but your forging skill and knowledge is amazing. Well done!
seeing you use the tool on the job site was a super cool!
Wow. I learned a lot from this particular video. Metallurgy, machining, production. It has it all. Well done.
I WAS thinking why not just lathe it! thank you for explaining it. very interesting 🙂
Good work 👍 and well done.. greetings from Syria 👋🇸🇾
Really interesting to watch. Couldn't guess what it was till the end. Brilliant
Great skills, reflections explaining and phantastic heatings….best blacksmith in sweden 🇸🇪
well!! if your work stands up to heavy industrial use, that's as good as it gets. Blacksmithing's no dead ancient craft. Success to your trade, mate. John Warner. Aust.
Finally got to hear your voice, should talk more often in your videos.👍
👍
Thanks Torbjo-rn.. just brilliant and inspiring! cheers
Hello Mr Torbjörn. The explanations were very informative for me. Thank
3:35 dang, you are really smooth with that camera trick
I really like your explanation and teaching. Thank you. You contributed to not just visual learning but auditory learning as well.
Very cool! I like the discussion on the crystalline structure of steel. In a future video will you discuss the heat treatment process and discuss the differences in quenching with water or oil and their different applications. Always love watching you work.
Thanks! I have an old video covering some parts here - ua-cam.com/video/Feod_795SOM/v-deo.html
@@torbjornahman thank you! I will watch.
Forging and machining in the same video, awesome episode!
Man i wish i had you as a shop teacher. You are awesome with old to the new .👍
Awesome video! I am a surveyor and have used that tool many times. In fact I have a few of the bits I am saving to forge into hardy hole tools.
Cool!
What a great video, thank you. The explanation of forged V turned opened my eyes, I had never thought of that.
Thankful for the extra explanations and narration in this episode.
Cleanest hands I've ever seen on a "Smithy". I'M first time viewer and could be the after you read my first comment.
Great video. Nice finish with the hammer. I am now a new subscriber. Also known as Ye Ole Caterpillar Cowboy
Sweet, thanks!!
I appreciated this format of video with some instructions on the theory of blacksmithing, why you did something a certain way, and the pros and cons. I'm always fascinated to learn about the grain structure and how the different processes, such as the different temperatures and times used in the normalization, quench and temper affect the properties of different alloys.
Blessings from the great state of Texas! I love your videos and this one was very informative. You should talk more. You know how to cut to the chase.
Thanks!
This is a rare forged tool build; nice work. We shared this video on our homemade tool forum this week 😎
Hah, nice voice you have, I like the info that you can give to us. Keep going!
أنت حرفي ماهر ومبدع، أيضاً فنان في مونتاج الفيديو، وشارح ومبسط أفكار جيد، شكراً لك على هذا العمل الجميل.
تحياتي من ليبيا 🇱🇾.
beautiful work and very useful for the workers who will manage their pain
Greetings to all from Yerevan, Armenia 🇦🇲
"Because it's fun to do" is indeed the main reason. All the other reasons come behind :)
:)
My compliments! You have the 'Knack' of the 'Old Timers' I used to watch on my coffee break. You have knowledge that is rapidly disappearing. This EXCELLENTLY crafted video (and most of your work in video) could serve as a back-up to conserve and protect for future generations of Metal Worker. thanx for sharing, Marcel
Thanks Marcel!
Thank you. That's a Great short and sweet of it. Forged is always better
That was a very simple but effective way to explain why forging the piece was better than just turning it. It was very instructive and interesting, thanks for that !!
Pleasure to watch you work, Thunderbear. I know nothing about shaping metal so the grain lesson was enlightening.
Enjoyed the process for a quality peice, and great video!
The editing just gets better and better!! I love what you do!
Thanks!
Great job and ... learned something again, thanks.
I loved this video. The precise hammer strikes ... I love the look and feel of a forged piece of metal and the process.
Most entertaining, most interesting. Thank you!😀
I really liked this style of video, Torbjörn. Your expertise is very well demonstrated through your videos without dialogue, but you're a great verbal teacher as well. It's nice to see another layer of your personality!
Thank you!
Reflections after many years of watching Your excellent videos. The big machine to the left: "As You decided, Sir." The old machine to the right: "Let`s wait for the result".
But the "old one" really has the charm!
I love the talking style of vido! Please make more!
That looks like a Pionjar rock-breaker jackhammer. I've more time than I care to think about on the dumb end of one of those. They're a beast of a machine, to be sure!
You are awesome, Torbjorn!!! I really liked that you gave an explanation of why forging is better than turning!!! Thank you for adding the new piece being used in the work process to your video!!
There was a lot at stake here!
That is why high performance engines have forged steel crank shafts
Thank you for the video that showed what that tool was for!! Well Done!!
Forging is the best way of conserving material and gaining/keep strength of your parts.
I second you explaining your thoughts. Thanks
Nice to get out of the shop and see your work in action…! Bravo 👏🏼
Excellent explanation, worthy of a great teacher, great work and beautiful video as always, I send you greetings from southern Argentina.
Heres a quick thing i seen you do that i really appreciate , when you quenched you did not just plunge it in and let it set.. you moved back and forth very rapidly.
Brother Torbjörn, what a wonderful class on forging and finish machining! Your use of tools and gentle touch under the hammer is perfect. You will chuckle at that statement. To doubt makes wisdom. The forged part ran very true on the lathe. Once again? A very impressive process. Well planed. Well done. I’m damn glad you left your prior profession! You are one of the best teachers we have.
What can I say? Thank you!!
I appreciate your explanation at the beginning. Your blacksmithing process is, of course, very interesting but the explanation is equally interesting. Thanks!!
I love the sound of the Beche air hammer, remembers me of my apprenticeship in 1970 on a shipard where I also learned fire welding. The original piece seems to have also been a forged piece out of a mass production. With the proven design flaws.
I enjoy every of your videos.
Greetz from Germany
Glad you showed your miss hit and how you overcame it. I watched it and cringed , if you have been there you know the feeling. Great content.
Thanks for the explanation; at first I thought while watching the process that forging the metal before working it with the lathe makes you waste less material than just using the lathe; although it is true that you save material, the approach to retain the grain material of the steel is well explained, thanks again
Very nice talking in videos and of course your style is unique. Interesting video!
I appreciate the time you took to explain why you hust didn't turn it on your lathe in the first place.
Another enjoyable one, love the explanations.. Your talking is right not overdone and filled with nonsense like so others
Thunder Bear, the control that you get with your power hammer is amazing #welldone and greetings from Australia 🇦🇺 Also a great explanation of the grain structure difference between a part machined from stock, as opposed to one machined after being forged to close to the finished size. Worlds apart in terms of strength, due to totally different granular structure.
Beautiful! Thank you
The problem with the old part was not design alone, somebody made a notch in it, you can see it where the crack startet. Seeing this often with chisels, when they got stuck they smack another chisel beside it to get it free and make a small nick or notch in it and thats the point where it will break after some time. The Sharp edges are doing the rest.
I was wondering how one even develops a fracture to break in the first place. Cold steel doesn't really just, er, snap. I couldn't imagine the scenario in which they broke it. You are probably right.
@@UnitSe7eneven smooth looking surfaces have microfractures. Add poor quality steel and poor/no heat treat and a stress concentration and heavy loading (especially shear) and a microfracture quickly becomes a crack
@@jackthompson6296 No.
@@UnitSe7enyes.
@@DH-xw6jp Not that anything he said was particularly _incorrect._ I know what a stress fracture is, and in that vibratory application it's clear that any weakness will quickly develop into full failure. But the question about how a fracture first developed is already best answered by the OP. Jack's reply actually answered nothing and included uncontextual information such as shear stress which this part does not experience, just as one example of the several. That's why OP's comment is good, and Jack's was just masturbatory, existing only to show everyone how much he thinks he knows.
3:33 Strong the force is with this one.
Dear Mr Ahman, I always enjoy your videos and the nice explanations you give. Already learned a lot from it!! I am very jealous of the beautiful workshop you have. Warm greetings from a metal teacher from the Netherlands
Many thanks
another lesson from a craftsman! tanx TA, good job! i started curing my sweet potatoes today.
Cool! Curing? I'm not familiar with the procedures associated with sweet potatoes.
curing makes them taste sweeter, and makes them keep till next season. keep in warm moist place for aproximately 2 weeks. then use .
I had an idea that I think would make a great video series, build a fly press, they are quite don't need electricity and are super useful. Hope you consider building one. Cheers.
I would need more tools for that... like a milling machine and probably a larger lathe... BUT it's a cool idea!
dein Projekt wird ewig halten! 🎉
Thanks for the video.
My two loves, forging and machining
Definitely the original concentrated the stress's into the point of transition for no apparent purpose
Great video and explanation 👍
Very happy to see somebody use forging for practical applications, and not just decorative pieces and trinkets, sadly very rare today.
Since you also have a lathe, have your ever thought about making a forged spade bit drilling metal ?
Can't say I have thought about that... spade drill for metal... interesting.
You had become my favorite forging channel
its like killing several birds with one ore
Im learning swedish
Im watching the beautiful sweden
and Im really interesting in forging and on top of that Im a CNC technician, its like one big soup of everything
so WIN WIN
greetings from Mexico
Ha ha, great to hear!!!
Very cool video. I really enjoyed your explanations in this one.
Well done. Thanks for the lesson. Take care.
