@@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 :)
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.
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!
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!
*- 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.*
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⚒
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!
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.
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!
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.
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.
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.
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 !!
I appreciate your explanation at the beginning. Your blacksmithing process is, of course, very interesting but the explanation is equally interesting. Thanks!!
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.
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 so much for the information on the grain etc. I was definitely thinking what you thought we were thinking :) I’m no metalworker of any kind let alone a blacksmith, but I always love your content. Thank you.
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!!

Thankyou for the explanation at the start and also later about the steel grain. Did not realise how important that was before, but now have learnt something new so thankyou. I do like your videos, the detail and precision is quite something and they’re always great to watch.
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
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
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 👍
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!
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.
Really enjoyed the combining of forging and milling. You explanation of why the forging was better than all milling was a great help in understanding why you did what you did. Thanks for sharing
Yet another great video. Love watching your entire process and the explanation at the end followed by the demonstration. Cannot thank you enough for these wonderful videos. 🤘🏼🤘🏼
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
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.
Very very nice video. Beautifully put together, informative and fabulous to see the piece being put to good use. A pleasure to watch, as always. Thank you very much.
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. 😊

Wow, that's a cool story! Yes, much the same principle!

I have to say I really like hearing you speak and explain things to us.
I second you explaining your thoughts. Thanks
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!
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
I really like your vids when you speak and explain your work, your English is great!
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.
I love his drafting table.
It's a bit low and has a odd shape....
Hah, nice voice you have, I like the info that you can give to us. Keep going!
It is much more fun to forge is the reason for this channel! Thanks for the explanation!
Thanks for the video.
I always get such joy whenever I see your videos. I admire your craftsmanship
Thank you very much!

Another smile put on my face by Torbjorn. Yes he is the best !!👍👍👍. JC🌵
Manipulating the grain structure not only improves strength but dramatically improves fatigue resistance and fracture toughness. Nicely done, sir.
Nicely done sir!
Cool to see surveyors in the vid having been a land surveyor for the past 13 years myself!
Cool!
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⚒
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!
Enjoyed the process for a quality peice, and great video!
Thunder Bear has done it again. Great job!
Love the talking and explaining In this video 🙏
I think all of your reasons for forging vs. machining are great, the most important one is the third.
Wow. I learned a lot from this particular video. Metallurgy, machining, production. It has it all. Well done.
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 .
Man i wish i had you as a shop teacher. You are awesome with old to the new .👍
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.
Demanding application indeed.
Once again you have shown what a highly skilled “metal worker” you are, but your forging skill and knowledge is amazing. Well done!
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.

I WAS thinking why not just lathe it! thank you for explaining it. very interesting 🙂
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.
The little hollar when the powerhammer struck the center by accident, i felt that on a personal level 😂
Nice to get out of the shop and see your work in action…! Bravo 👏🏼
I loved this video. The precise hammer strikes ... I love the look and feel of a forged piece of metal and the process.
