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.

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!

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!

Manipulating the grain structure not only improves strength but dramatically improves fatigue resistance and fracture toughness. Nicely done, sir.

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.

*- 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.*

Nicely done sir!

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!

@Skinflaps_Meatslapper

Sometimes that touch mark will create stress risers of its own, so it's understandable why he didn't add it.

I have to say I really like hearing you speak and explain things to us.

Tools made in Sweden are well made. You just proved the point. 👍😊 Great video. Thanks for sharing.

Wow. I learned a lot from this particular video. Metallurgy, machining, production. It has it all. Well done.

seeing you use the tool on the job site was a super cool!

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.

Love the talking and explaining In this video 🙏

Once again you have shown what a highly skilled “metal worker” you are, but your forging skill and knowledge is amazing. Well done!

I really like your vids when you speak and explain your work, your English is great!

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!

I think all of your reasons for forging vs. machining are great, the most important one is the third.

I loved this video. The precise hammer strikes ... I love the look and feel of a forged piece of metal and the process.

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 !!

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.

There was a lot at stake here!

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.

@@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.

Pleasure to watch you work, Thunderbear. I know nothing about shaping metal so the grain lesson was enlightening.

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

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.

I appreciate your explanation at the beginning. Your blacksmithing process is, of course, very interesting but the explanation is equally interesting. Thanks!!

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

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.
