I'm an old retired mechanic / welder . This guy is the ultimate Cool Hand Luke.

Not really a grate idear if you have powerfull engines with lots of torque changes. I hope this one is for something unimportand. 1. Crankshaft are forged wich means they lose stability if heattreated with a torchflame 2. Crankshaft are balanced on rotation wich is necesary to not brake at 3000 - 5000 rpm. Welding it together will unbalance it. 3. every Crank on the shaft has a precise location. if it out of place the engine piston will not be at the right position when the fuel is ignited wich can cause futher damage to the engine. And will make it run dirty. But I am sure they just cant get or afford a new one, so it is the only way to go.
I am in awe of this guy. His "health and safety" is a bit behind modern practice (wristwatch, ring, no eye protection) but the skill level is something I haven't seen for decades.
WOW, one of the best 47 minutes I have spent recently. What a Guy, did the whole job from start to Finish. Such a constant weld pattern, puts shame to a lot of Industrial welding that come out the factories these days. Well done, excellent job all round.
@@hanspeterraatz4928 If you had watched the WHOLE welding process, you would have seen that the ROOT passes were just as good and had NO inclusions.

Clearly he has done this so many times it is second nature. I have never seen a crankshaft rebuilt this way. We used to rebuild two stroke cranks which were built up type, but these are pressed together. I would not have believed it financially viable to weld up a broken crank, but clearly where he comes from it is. Hats off to you Mr Engineer, you are a hand skills master.
How long will that last? If an original crankshaft brakes, a welded one can't take the strain. I once had my tractors clutch case welded, it did not last long. The weld itself is stronger, but the joining pieces are weak.
@@hanspeterraatz4928 Well it has a spigot and the front section was pressed on - probably strong enough for what it has to do. Must be strong enough otherwise he would have only ever done 1 and no one would bother with it again, unless they like pulling motors apart to regularly change crankshafts.
@@hanspeterraatz4928 I think if this were the first time he's repaired like this you might have a point. Clearly he's done this successfully a hundred etc times and this is repeat business.

Я тоже не знаю будет ли это ходить..... Но нормальный токарь за один проход сантиметр не снимает. Он любит свои резцы и станок. Если он действительно профи.
Before everyone gets the idea that they can do this with what came out of their old Chevy or Dodge, you best consider this: This crank is NOT cast iron. It is in reality forged steel. That little gob of weld on the end of the first piece is their way of checking to see what material it is. If it doesn't take a weld like that they junk it. Once the material is established you can see how it machines. Cast iron does not machine large chips as shown but more like a sand or powder. Forged steel will leave large chips like those shown. Another telltale is at 11:34 with the other end of the crank. You can see how the throw has been cut down with a cutting torch to save on machining. Cast iron will not cut very well if at all with a torch. Also, if you look carefully, from time to time you can see the marks left from where the forging dies join together. You can repair a forged steel crank this way and if you are careful to get the two pieces back into alignment there is no reason why it won't work. I have seen large cranks used in industrial engines that were fabricated from smaller components and welded together much the same way as this.
@@nzsaltflatsracer8054 I believe you are right on that 6012 rod. AC/DC works well for poor fits and deep grooves, low easily removed spatter and good dynamic loading capabilities. It would work well here. It is definitely not 6010.
@@georg1875 They don't seem to bother with preheat. Also there seems a stack of identical cranks waiting for repair so maybe the original isn't strong enough for the job.
I'm a machinist and I just went to school. I followed everything this guy did and he is spot on. The welding and straightening of the crank is at the top of his ranks. I want his autographed picture on a Tshirt..
To all the people saying to just get a new crank: We are so blessed to have that option, a lot of people don't have that option. I am blessed to buy and order new parts for my business, and to drive a new truck. This repair was probably as good as you can make it given the circumstances

Absolutely amazing. True artists indeed. Making whole new crank shafts with a machine is one thing but to repair them by hand using basic tools is another. God level.

Given that the machinery he is using is not exactly state of the art he is without doubt a very skilful engineer, probably self taught, and commands great respect. Whether the crank will last is a matter of how it will be used...but he will always be there to repair it again. Brilliant amazing person...top marks
@@mick1gallagher That's one thing I noticed on all these videos. People who have no clue about machining and other trades praising this reckless and dangerous behavior like it's something to aspire to. Literally everybody that has worked on a lathe for a couple of years can do what this guy did. We know nothing about how well this thing actually turned out, the result could be horrendously bad, you can't tell from just looking at it.
No machinist that have any idea will make a loose ignorant statement like this. IF you are a machinist you will know exactly why we don’t do ridiculous repairs like that.
looking at the failure it looks like a failure caused by vibration ( that's why engines have harmonic balancers ) if I'm right and they manage to weld it accurately and balance it, it's going to probably be as good as a brand new crankshaft it could even be better, it just depends on the care taken by the original manufacturer,
I have watched this and it’s truly outstanding. I have been building and modifying engines for 40 years but this is on another level. If this chap had all the equipment available in our country what he could accomplish would be unbelievable. On a humorous note I couldn’t help notice the safety gear he had when welding the crankshaft to save weld splatter burning his toes in his sandals. Namely what appeared to be a piece of cardboard or something from a welding rod box? First class you are in a league of your own👍👍
machinists are not concerned of wearing minor safety gears in these coubmntries. .never heard anyone dies of accident by not wearing one. .what attracts is his smoking. .he could die of lung cancer in an age where he was supposed to be retiring ang relaxing. .

I'm a 37y/o woman who's only mechanical experience is changing the motor oil on a car I had once like 12y ago... but I can't stop watching your videos. It's so satisfying to see such skilled laborers like clockwork! Keep it up!
Out of all the things iv seen fixed. This guy is about the best even looks after his machines the place is clean and tidy first time if seen a clock being used as well. Even his welding shoe was a step above the rest. Granted one day that lathe is going to bite him.
It only twisted off the one end..😄 That's why he's got that pile of repaired shafts behind him because they come with a warranty: "Buy one and if it breaks where I repaired it we'll give you another one." 😄😄
@@user-br3ou2cs9o I don't understand your point. regardless of where it twisted you still wouldn't be able to use it, and no matter how skilled you are, you will never be able to restore the strength of crankshaft anywhere close to what it was from the factory.. Look I'm not saying you can't throw that crank back into an engine and not get any use out of it. but I will say that after 25 years of building/rebuilding engines, diesels and hi-po applications alike, I and most mechanics/machinists would never think of putting faith into a crankshaft that was twisted in half then welded back together, into any of my engines. It's just way to risky and the damage it would cause would most likely destroy the engine it's in. The cons severely outweigh the pros.
Very Good work. Did anyone else notice that he didn't quite line up both parts of the crankshaft at 24:39 ?... but he did correct this at 25:19 when he put the whole crankshaft back on the lathe and hammered it downwards to rotate the broken end of the crankshaft so that it is aligned perfectly...
My high school machine shop instructor, Phil Meyers, taught us to tighten from all three of the drill chuck key points. Just like this guy did. Mr Meyers was a hell of a teacher.
I liked how fast he lined up the short end in the 4-jaw chuck but when I saw him sand the journal, it brought back horrible memories. My toolmaker made a mistake sanding and lost his Entire Right Hand. The sandpaper bit-in and he couldn't let go. I don't mean mangled but ripped Off @ the wrist. He's getting Way Too Careless!
Impressive! Very impressive! I never knew anyone repaired crankshafts. With the amount of work that went into that repair I would have thought that it would be cheaper to just go out and buy a new one. That was neat to watch just the same. Well done!

Thats far far away from amazing skills, there are so much failures that even to lazy to describe all. For example there was no pre-heat before welding, no balance, it spins in waves, ect, ect. Was fun to look, but I don’t even think attempt to use it myself or suggest for someone. It’s price is same as was before repair - scrap-metal. Normal crank is way much precise thing.
@@antanaslomsargis8952 I hear what you are saying, but looking at all the crank shafts sitting for repair he must have a good trade, remember parts are not available in a lot of countries particularly the poorer ones, also they are when available prohibitively expensive. I found his checks although not as precise as in a factory setting, he was very particular about alignment of the journals so I cannot fault him for doing the best with what he has available to him.
The skill level of this guy is amazing and I'm sure if you check this Crank professionally the results will be great. This guy has engineering in his blood and does not need university degrees
I'm sure he lives a full rich and happy life and is well respected. I imagine it gives him great satisfaction to keep another vehicle on the road that would be non viable at replacement factory spare parts prices.
Fascinating! Regardless of whatever "best practices" are and or if it will last , its amazing that this could be attempted at all, and with such precision with manual tools and his god given 5 senses (mostly his eye and hands). I was brought here by youtube's algorithm, and been binge watching various other craftspeople/machinist/fabricator/engineers or what ever you may choose to refer to them. It would appear to me that not one shop will fix all...I think you have places that specializes in various disciplines like in this case he obviously a master of repairing cams and other may say be for axles, engine blocks etc. The guy may not have a degree in engineering (I assume) but my goodness amongst the lot Ive seen so far, this one seems to be one of the best, and you get a sense of confidence in his work. Of course there are the opposites as well, just got reminded of outliers as with life in general..... Really inspires me to not take things for granted and consider what can be done if you put your mind to it......
1- If they break the second they start the engine what are all those cranks doing there? Nobody can be that stupid to keep doing something that just doesn't work. 2- Check the South Bend Lathe Book "How to run a lathe" - YOu will find that the way he works is the exact same way we have been running lathes in machine shops all ove rthe world for well over 100 years.
As amazing as it is, what amazes me more is that he still has a full set of fingers on each hand. That's not being critical, just an observation from how many times he turns his head away whilst machining. Anyway, well done to that man.
You guys are wonderful. Here in Germany, you only hear "broken, buy new". This is terrible for sustainability in our planet just to throw everything away. You guys are heroes!
All that calibration done by eye with such minute measurements is impressive. I don't know how confident I would feel installing that crankshaft into an engine I intended to use though with regard to the tolerances and stresses etc. Lol. The part at the end (44:00) watching his hand acting like the piston made me LOL!!!
Damn, wow. To the comments about this being a bad idea - yeah, if you can get/afford replacement parts. But in the end it's your local economics and circumstances that make the call. If his customers find value in his work and he's making a living, then 👍
@@billmiller7138 Most likely the engine will be re-task with something that puts far less stress on it than what broke it in the first place, like running a sawmill or a generator instead of being in a delivery truck or whatever it was that broke this in the first place. If they try to use it for the same application it'll break in a fraction of the time it originally did and I have the feeling these guy's know that.

It is so, because it's usually cheaper to buy a new part than pay a skilled machinist. In a case, that the component isn't available (mainly for vintage stuff), the repair is done in similar fashion.
I've never seen this kind of repair. Much respect for your abilities. But I'm curious if the crank shaft would need to be re-balanced since the counterweight was slightly faced?
Did you see that small cross-drilled hole? It was used to align the 2 parts. I don't think they showed how that hole was drilled - my guess is they had some kind of drill plate that would accurately align that drill.
@@blankeomwenteling8135 First of all, any engine rebuilding in this country would never dream of a repair like this. And engine rebuilder would not have the welding expertise to ultimately analyze this repair - only master welders would. i didn't see any observations that this break was after the 1st cylinder. Neglecting supercharger loads, that is the main bearing journal that has to transmit only 1 cylinder of torque - 1/4th the torque produced at the aft end of the crank. So that front journal is very oversized. The loss of load carrying section due to the pilot shaft feature is at most 1/2 so based on area resulting on 2x the load, but that journal only sees 1/4th the load. So the weldment sees about 1/2 the load. The key to life is crack initiation. The highest torque shear is on the surface and that looks like a good weld. The lowest is at the root. The issue with the root is the termination of the weld at the pinion feature. This should be a pretty high Kt no matter how proper the weld is. But again, it all depends on the reduced load of a front journal. Then there is what amount of annealing occurred after all that weld was laid. There was a lot of weld and so a lot of heat, perhaps enough to stress relieve areas. Because the ring of weld is hotter, it grows relative to the pilot feature. This will cause tensile yielding as it tries to pull away radially. Upon cooling, residual compression will exist (!) - and this is exactly where the root weld is. There are many factors that determine how much life this repair will have and part of that is how the engine is used. Light Duty vs Extreme Duty? What are the snout loads? Supercharger? Bottom line is in his market, business appears to be thriving so it looks like he has a lot of happy customers. A USA guy would never attempt what this guy mastered and turned into a business.

Amazing work in a relatively primative shop - very impressed!!! I am a bit confused, however. It seemed like he was using the two pieces from the same broken crank, but with the machining he was doing that couldn't be the case as the journal's width would be narrowed. So he was using a piece from another crank - right? Or was there something I missed??? Please advise. Anyway, keep up the videos, I enjoy watching how the other parts of the world get things done!

Before everyone gets the idea that they can do this with what came out of their old Chevy or Dodge, you best consider this: This crank is NOT cast iron. It is in reality forged steel. That little gob of weld on the end of the first piece is their way of checking to see what material it is. If it doesn't take a weld like that they junk it. Once the material is established you can see how it machines. Cast iron does not machine large chips as shown but more like a sand or powder. Forged steel will leave large chips like those shown. Another telltale is at 11:34 with the other end of the crank. You can see how the throw has been cut down with a cutting torch to save on machining. Cast iron will not cut very well if at all with a torch. Also, if you look carefully, from time to time you can see the marks left from where the forging dies join together. You can repair a forged steel crank this way and if you are careful to get the two pieces back into alignment there is no reason why it won't work. I have seen large cranks used in industrial engines that were fabricated from smaller components and welded together much the same way as this.
hahah i agree. i see the electrode 7018 or 6010 hard steel he was welding so it is not cast iron.
@@wendelllovatti The color of the weld & slag isn't right for a 7018 or a 6010, looks more like a 6012 to me.
@@nzsaltflatsracer8054 I believe you are right on that 6012 rod. AC/DC works well for poor fits and deep grooves, low easily removed spatter and good dynamic loading capabilities. It would work well here. It is definitely not 6010.
@@oh8wingman what are your thoughts on preheating that crankshaft before welding it?
@@georg1875 They don't seem to bother with preheat.
Also there seems a stack of identical cranks waiting for repair so maybe the original isn't strong enough for the job.

@@Mekzuc91 not can’t , but will not , that’s why it broke after the previous repair. If you are a tradesman in this field you will understand.
looking at the failure it looks like a failure caused by vibration ( that's why engines have harmonic balancers ) if I'm right and they manage to weld it accurately and balance it, it's going to probably be as good as a brand new crankshaft it could even be better, it just depends on the care taken by the original manufacturer,
I have watched this and it’s truly outstanding. I have been building and modifying engines for 40 years but this is on another level. If this chap had all the equipment available in our country what he could accomplish would be unbelievable. On a humorous note I couldn’t help notice the safety gear he had when welding the crankshaft to save weld splatter burning his toes in his sandals. Namely what appeared to be a piece of cardboard or something from a welding rod box? First class you are in a league of your own👍👍

@@user-br3ou2cs9o I don't understand your point. regardless of where it twisted you still wouldn't be able to use it, and no matter how skilled you are, you will never be able to restore the strength of crankshaft anywhere close to what it was from the factory..
Look I'm not saying you can't throw that crank back into an engine and not get any use out of it.
but I will say that after 25 years of building/rebuilding engines, diesels and hi-po applications alike, I and most mechanics/machinists would never think of putting faith into a crankshaft that was twisted in half then welded back together, into any of my engines.
It's just way to risky and the damage it would cause would most likely destroy the engine it's in. The cons severely outweigh the pros.
Very Good work.
Did anyone else notice that he didn't quite line up both parts of the crankshaft at 24:39 ?... but he did correct this at 25:19 when he put the whole crankshaft back on the lathe and hammered it downwards to rotate the broken end of the crankshaft so that it is aligned perfectly...
My high school machine shop instructor, Phil Meyers, taught us to tighten from all three of the drill chuck key points. Just like this guy did. Mr Meyers was a hell of a teacher.
It’s a 4 jaw
Would love to see this guy in a modern machine shop ....after a year or so of learning how they work he would be capable of ANYTHING!
I liked how fast he lined up the short end in the 4-jaw chuck but when I saw him sand the journal, it brought back horrible memories. My toolmaker made a mistake sanding and lost his Entire Right Hand. The sandpaper bit-in and he couldn't let go. I don't mean mangled but ripped Off @ the wrist.
He's getting Way Too Careless!
There are very few people who know how to make these repairs, this works, you are a good turner and a very good welder. A great job !!!

Thats far far away from amazing skills, there are so much failures that even to lazy to describe all. For example there was no pre-heat before welding, no balance, it spins in waves, ect, ect.

Fascinating! Regardless of whatever "best practices" are and or if it will last , its amazing that this could be attempted at all, and with such precision with manual tools and his god given 5 senses (mostly his eye and hands). I was brought here by youtube's algorithm, and been binge watching various other craftspeople/machinist/fabricator/engineers or what ever you may choose to refer to them. It would appear to me that not one shop will fix all...I think you have places that specializes in various disciplines like in this case he obviously a master of repairing cams and other may say be for axles, engine blocks etc. The guy may not have a degree in engineering (I assume) but my goodness amongst the lot Ive seen so far, this one seems to be one of the best, and you get a sense of confidence in his work. Of course there are the opposites as well, just got reminded of outliers as with life in general..... Really inspires me to not take things for granted and consider what can be done if you put your mind to it......

Oh for sure hes on it and ripping it up. Ha ha, my shop teacher would of freaked on this guy. No safety glasses, long sleeves, loose wristwatch, that long night shirt. He sets the chuck key on top of the lathe and everytime he reaches for it, or he brings the emery cloth around, his sleeve looks like its grazing the workpiece. Remember those films and pictures they showed us in shop class, of guys wrapped around shafts and chucks or their arms ripped off. He's rolling the dice 🎲 🎲
This is how the bulk of the work was done that industrialized the west....it's fun to be able to watch in real time a nation going through it
@@meyou245 Its India. They dont worry about safety gear and health.
@@nelsnelstone3488 safety this... safety that... yawn
Master craftsman's at work. Love the work you people do. Cheers from Australia 🇦🇺
Phenomenal work! I have to admit I would not have expected such work from your shop.
Absolutamente espetacular ; parabéns , você é o cara .
Outstanding work I know this is the way things are done there, but the world could learn a lot from them. This is true recycling and the skill of this man is amazing. Today the world is a throw away society which is a true shame. The other shame is this man probably just got paid a pittance for his work.
It is so, because it's usually cheaper to buy a new part than pay a skilled machinist.
In a case, that the component isn't available (mainly for vintage stuff), the repair is done in similar fashion.
If he was paid more, then they would just throw away and buy a new one. It's a double edged sword.
Cost of living is a pittance too. And he can probably still afford to buy a house
Your grand grand father probably used the same method to fix crankshafts.
انت فنان... اتحدى احد ان يتقن مثل عملك 💪💪💪
I try to be a good mechanic, i rarely make comments on youtube. but i had to watch the whole video with great respect. thank you.
I've never seen this kind of repair. Much respect for your abilities. But I'm curious if the crank shaft would need to be re-balanced since the counterweight was slightly faced?
Most of the work was done on a main journal. So, probably the balance is just fine.
Yes right. I think you need to rebalance but i amaze the abilities of this man.
What about the hardness?
The kind of welding used ?
Did you see that small cross-drilled hole? It was used to align the 2 parts. I don't think they showed how that hole was drilled - my guess is they had some kind of drill plate that would accurately align that drill.
@@blankeomwenteling8135 First of all, any engine rebuilding in this country would never dream of a repair like this. And engine rebuilder would not have the welding expertise to ultimately analyze this repair - only master welders would.
i didn't see any observations that this break was after the 1st cylinder. Neglecting supercharger loads, that is the main bearing journal that has to transmit only 1 cylinder of torque - 1/4th the torque produced at the aft end of the crank. So that front journal is very oversized.
The loss of load carrying section due to the pilot shaft feature is at most 1/2 so based on area resulting on 2x the load, but that journal only sees 1/4th the load. So the weldment sees about 1/2 the load.
The key to life is crack initiation. The highest torque shear is on the surface and that looks like a good weld. The lowest is at the root. The issue with the root is the termination of the weld at the pinion feature. This should be a pretty high Kt no matter how proper the weld is. But again, it all depends on the reduced load of a front journal.
Then there is what amount of annealing occurred after all that weld was laid. There was a lot of weld and so a lot of heat, perhaps enough to stress relieve areas.
Because the ring of weld is hotter, it grows relative to the pilot feature. This will cause tensile yielding as it tries to pull away radially. Upon cooling, residual compression will exist (!) - and this is exactly where the root weld is.
There are many factors that determine how much life this repair will have and part of that is how the engine is used. Light Duty vs Extreme Duty? What are the snout loads? Supercharger?
Bottom line is in his market, business appears to be thriving so it looks like he has a lot of happy customers. A USA guy would never attempt what this guy mastered and turned into a business.
Skvelá práca a neuveriteľná zručnosť. Od vás sa môžu učiť konštruktéri zo svetových strojárskych firiem.
Souhlas
@@Killeroz Zaujímavé sledovať majstrov z týchto krajín ako dokážu zrecyklovať a opraviť pre nás neopraviteľné veci. Autobatérie a kľukové hriadele ma ale nazaj dostali. Aj tá zváračka z asfaltu je zaujímavá🤣🤣🤣.
I like this guy! Repairing such a monster piece of metal is as simple as drinking a cup of tea!
I feel so privileged to have watched such a craftsman at work.............................. thank you so much.
i want this guy to do all my machining. That was awesome and amazing!
Amazing work in a relatively primative shop - very impressed!!! I am a bit confused, however. It seemed like he was using the two pieces from the same broken crank, but with the machining he was doing that couldn't be the case as the journal's width would be narrowed. So he was using a piece from another crank - right? Or was there something I missed??? Please advise. Anyway, keep up the videos, I enjoy watching how the other parts of the world get things done!
It is two salvaged cranks
I noticed that too. So the title of the movie is wrong. It's not "a" broken shaft, its two. Anyway, excellent movie and work. Many thanks for uploading.
Yes....he had to use two cranks to make one.
I thought exactly the same thing
@@MrDehicka Thanks - that's what I thought, butthe title was somewhat misleading!
Amazing work and all his fingers and thumbs seem fully operational . Very impressive!!
Bravo to this man !! Doing that every day, for hours !!! It's so physical !!
Highly professional work, we had wheel sets restored in the locomotive depot, my respects to the master!
