THIS operator is the best I've seen on this channel of misfits and questionable machines. He actually knows his stuff and it shows in the little things he does.
Yes indeed. Taught me one thing. Use a packing piece on top of the tool stop the screws digging into the tool.
@@codprawnI noticed that as well. Using a scrap piece on top of the tool shank is what we were taught in tech college many years ago to preserve the tool shank and prevent swaging damage. I still do it that way to this day.
Things I've learned in this video: Cast iron machines as steel, chipbreakers in your lathe tool are evil, stop the lathe chuck by hand when the jaws produte, check first with a micrometer, then attack the part ferociously with a file, clean the milling chips with a finger close to the endmill, never ever attemp to clean a machine: The chips add mass and rigidity, and very important: Machining is a force and speed contest, the fastest and strongest machinist win...be sure to tight everything with all of your force.
20 bucks says you can't even grind a HSS tool bit and wear gloves around rotating machinery.
@@mathewmolk2089 ，，，，
Thats the way they do it. No wonder so many die in workshop accidents.
And yet, it still came out fine ….
Dude, when you don't have a cutter with a replaceable plate and you need to keep a soldered tool, a chip breaker is a real evil. This halves the possibility of a new sharpening, and for a real master this is tangible money. As for cleaning the machine, this turner plows in a day so that the word "meow" is pronounced at the end of the day by letters, and I understand it perfectly, it's not about the CNC sitting on a chair and removing finished parts.
This material is not cast iron, it is steel. Cast iron does not form long, continuous chips.
You are absolutely right. But, having made literally thousands of pounds of steel chips in my 60 year career as a machinist. Even most steels will break chips with the right tool, speeds and feeds. Cast iron isn’t steel. It always breaks. It is inherent in its properties. Steel must be bent to break. This is done with a chip breaker ground into the cutting tool. A thicker chip will break easier than thin chips, making higher feeds more useful when hogging. There are always trade offs, but there is rarely no good excuse for such long and stingy chips.
You stole my words however, the type of steel is unknown. The operator's talent is knowing how to input numeric values on the calculator for the proper change gears to use for the gear pitch and major gear diameter.
You have to factor in that in a culture where people have little,little goes to waste. That long stringy swarf is far easier to collect and sell on too!
@@areyouundoingthatorwhat9181 It's much easier to collect small chips, long stringy chips take up far more space and are more difficult to handle. If you have chips 1/2 to 1 inch long you can fill a 50 gallon drum with far less unused space Vs chips in the 12 inch length range. His access to tooling is less then in western countries where you could just tell you tooling supplier what you want and he'll have to you next day. I'd imagine he has to make comprises with tooling, and likely having a tool that does many jobs is more important then chip uniformity. The fact that you can just walk down a street hand him your old part and he'll make you a new one for I'm sure extremely reasonable price is pretty damn cool.
yep i.ts forged steel thats for sure
You have to give these guys credit for a great job done on some very old machines. The safety matter is another issue.
Life in Pakistan is cheap, if a guy winds up missing a hand he essentially starves and they find a new machinist. Safety guards? Who needs em? When I was there they really didn’t have it together to have clean water and sanitation, much less picking up the he dead.
you can hear it in these old machines how wore out they are
@@Slick1G3 You've obviously never been in a machine shop before, these machines are fine. There is nothing "Genius" happening in this video, they are using the correct tools for the parts they are making , albeit in an incredibly unsafe manner.
Older machines are preferable to modern ones in small shops like this, unless you've got big bucks to spend on state of the art CNC, you simply can't beat the reliabilty and rigidity of old school cast iron. I have a small workshop in my garage, my mill is a Centec 2B date stamped 1958, my lathe is a Longbed Myford Super 7 from around the 60's - 70's. For manual machines they'll outperfrom anything you can currently get brand new and at a fraction of the cost.
Totally not "cast iron" as stated in the title. Thank the gods, steel will be much stronger.
Knew someone would’ve beat me to it. Obv not cast iron!
Thanks hydroman99 ! I don't want to watch the video but wanted to make sure someone pointed out that "Mechanical Skills" is a KZhead "influencer" who is miseducating our youth with his lack of due diligence and self education on his subject matter. I think it is awesome that anyone can make a good living with hard work, by posting on KZhead. I just wish those who choose to do so would have enough self respect to teach the correct science (metallurgy in this case).
My thoughts entirely.
What about the hardening process 🤔
@@kevinsellsit5584 Look up the definition of metallurgy and you’ll see that it has NOTHING to do with this video. I guess you need some more education now…
I see the keyboard master machinists are out in force today.
Indeed they are. Idiots that probably couldn't use a CNC machine, let alone a lathe from the 1940s or 50s or 60s... "Oh noes!! I can't read these confusing knobs!!!!!"
So true Neil ,they make me Piss ,what they are saying !!Thats proper Old School Machining ,been there for many years ,no CNC ,s job on job off ,small Machine Shop ,Clean out at the end of the day ,Gear Cutting Too,Great Job Boys !👍👍👍👍👏👏👏
Indeed so. I bet most of the people leaving comments have never owned a lathe. I have 11 I think now. I am just an amateur. I can do very precise work but I take forever. I could never make a living at it.
The upkeep and cleanliness of the equipment and area is second to none...😳🍻
When I see those flow chips, I get goosebumps all over. When I see him pulling on those with pliers while the machine is still running, it gets even worse. He uses up all his luck all day long.
At least he isn't using his hands. He knows what he is doing trust me.
I use these videos as exercises for new fitter/machinist students to watch and identify dangerous workshop practices that can become dangerous accepted habits - keeping the workplace clean is a very important part of the job - I used to visit many machine shops and could tell the professionalism of the work team by the cleanliness and order of the equipment . when I was pricing a job I would include cleaning the machine and work area as part of the cost of the job - as an apprentice that was the first task to learn - cleanliness and safety of the work area - second lesson was to cultivate a safe attitude and respect for the machine - third lesson was to identify a dangerous situation and be compelled to act to minimise or eliminate the danger -
It’s the 3rd world, living and working in sh1t is second nature!
Because they don't look like you ?
@@juju-rt8ek … don’t look like who? Still nothing wrong with how they look, it’s the way they behave. The fact is some cultures are better than others.
@@andyxox4168 they are genius to accomplish what they do with what they have. They are desperate to make money, poor infrastructure. They are leaders in tech and medicine. They are the major contributors in our big companies in America. Americans made fun of the Japanese, now Chinese manufacturing.
@@andyxox4168 How does culture tie into proper workshop protocol or safety? It seems you just wanted to drop a snarky comment about this culture and took the opportunity. I've seen old Germans in workshops handle bench drills like a toy. Clearly its not a matter of culture here then, but more about a person having enough confidence and experience working with a machine to avoid injury without taking safety precautions.
The material he is cutting is, NOT, cast iron Cast iron does makes powdery, flakey , small chips
Remember those days well, that's how my engineering days started. So 57 years ago. No fancy computer tech. That's a special gear cutting machine designed for the job. Not cast iron, no proper chip break on the tool. Will require surface hardening and tempering for long term use. Pretty basic stuff.
One of my main concerns is the type of chips he makes. When I was a youngster I learned how to grind a chip breaker in high speed steel tools. I did see a coworker get tangled-up in such stringy chips. He nearly lost his arm. BE SAFE.
lol be safe is not an option there they smelt steel and move it around wearing sandals:) but they do a exelent job tho
You're worried about his safety when he doesn't even wear shoes or safety glasses?
He might make rubbish chips but his chicken biryani is top notch!
This "genius" doesn't understand that making continues blue chip is incorrect. He is overloading the motor with too heavy a cut and no lubricant. He'll wear out the tool it and motor. Also those "chips" pose cutting danger to the worker. I'm a metalwork teacher and teach the correct use of lathes. This guy is an amateur at best
@@paulfredriksteiner Singlets and thongs are attire for beach going, not working in a metal workshop. How would you like one of those shafts fall on your toes.You'd be a cripple for life. The whole place is a joke.
Я уже начал переживать, что не бросит готовое изделие на земли. Но все обошлось, бросил. Интересно, они вообще закалку и отпуск шестеренок делают.
it's not genius, it's common way of making gears
He is genius because still using a 100 years old machine.
@@raufjaleel8317 Probably easier to use that a modern one with electronics and computers all over the show.
Yes we can all criticise but the job got done with the resources available. Another machine kept working & a can do attitude. Well done! These are the sort of positive people the world needs more of, getting the job done without a hundred excuses!
well said Gary, , I do not think it was cast iron bar though......amazing what some are capable of with so little equipment.....
@@ypaulbrown They guy shooting the video has no clue what material is being used, it's obviously some grade of steel. I hope he's sharing any profits from You Tube/Google although I doubt it In the USA that would probably be a $2000.00 machine job and take 3 months (unless it was a defense contractor, then it would over un by 6 months and cost $20,000)
Why bother getting the job done if the components produced are rubbish and will fail.
@@adybarker4733 Hey yeah you're right. Why bother trying to do anything!
Yes, they got it done. They could lose a limb or even die because of their carefree attitude
Meu amigo você é um verdadeiro torneiro mecânico nota 10000000000000000 parabéns Deus abençoe sempre sua vida e sua família também.
When roughing a part like this you need to slow the rpms and increase the feed rate. This also helps break chips instead of the dangerous razor sharp strands. It's also faster and puts the heat into the chips and off of the part. Genius? Not quite.
Man, grind a chip breaker in that cutter. Those long razor sharp ribbons make my skin crawl.
It is truly amazing that this can be done with the tools available. It is a triumph of expertise over coming limited equipment. Thanks. Cheers.
Hardly limited equipment, they have a gear hobbing machine to cut the gears, if they were doing it with a milling machine and dividing head driven on the end of the bed, then I'd be rather more impressed, however the lack of even the most basic safety and cleanliness is just dreadful, I hate to think of the number of those maimed and worse in these workshops.
No way that’s cast iron….that is steel for sure…those stringy chips are killers!
Ha! I came here to say this. I was suspicious but as soon as I saw the chips I knew. Iron smh
Yeah buddy, get the apprentice to clear those finger removers out.
Nice work
I was surprised that he didn't use some cutting fluid, I actually felt sorry for the cutting tool that was taking such deep cuts.
@@potrzebieneuman4702 it was invisible cutting fluid I saw it lol
nice to see he has a clock to true the shaft up. usually they use a bit of bent wire in a scribing block.

I wish I would have been able to learn a craft like this. This is fantastic.
you'll learn that in a week if you were there
@@eitantal726 working on a manual lathe is a skilled job, takes a considerably longer time, these guys learn from a very young age under a mentor
That is the first time I have seen one of these Pakistani machinists use a dial indicator instead of a bent wire. Good job fellas
Never understood why the last stage is always just chuck it on the floor and roll it around in the dirt
thank you

These guys are amazing as far as I'm concerned. Side by side comparisons be damned, job gets done. Fast as hell, no premadonna crap going on either.
Yeah, right? What is a lost finger, right? We've got the other nine...
And no safety glasses to boot!

Incredible work you make my friend perfect and nice job. Congrats you and the others tech team, THANKS for sharing your experience with us. God blessed.

I've had to operate my own Machine Shop to First World standards for 50 years and I probably should be angry at myself for not moving to one of these countries where I could have taken so many short cuts if I wanted to take advantage of really cheap labour, non existent health and safety laws and customers' lack of interest in demanding high standards from their suppliers. No wonder manufacturing industries in the West are dying - how can we possibly compete?
A masterpiece, perfect work and that with such old machines.
not so perfect when he has to run a file on it but the easiest thing to do to compensate for the sloppiness of the machine i guess
Thats steel. Nice work!
Bravo Bravo perfeito o trabalho show parabéns pelo seu trabalho 👏👏🤝👍🇧🇷🇧🇷🇧🇷🇧🇷🇨🇮
Al fin encuentro alguna persona que le canto la justa pura verdad . Turning cast iron the chips allway break , plus turning high seep the tool get doll fast ,only it the way to used carbide tool. Thank you , Gracias desde ONTARIO CANADA.
Great and Brilliant job ...!!! regards from kuala lumpur ...!
I used to work in a machine shop a nice clean area always had a clean workstation I don't see how they can work in filth and when you're doing your calipers you don't throw your calipers down on the machine you don't hit them on things micrometers you don't tighten up on the micrometers when you're measuring something you use your finger to turn it and lay it really soft on the thing that you're cutting you don't tighten up on the micrometers
Very Informative. What about the urger. How do you make it
moi j'aurais dégrossi toute la pièce a 1 mm de la cote finale ensuite j'aurais vidé mon bac a copeaux pour être en sécurité pour pas que les copeaux s'enroulent autour du mandrin et les gorges de circlips je les auraient fait a la fin en mettant le modèle sur la machine a chaque fois pour faciliter le travail conseil dun tourneur et fraiseur depuis 41 ans , bon courage a vous
Dude is nuts grabbing at nesting chips like that. He must be extremely lucky.
Very impressive and Sign of Hardworking with very technical minute Calculations and skills ..... Thumbs up bro

*Machinist hate him for this easy trick.*
Awesome, analogue, skill !.
There should be a society set up to prevent cruelty to lathes.
I should show this to my friends and family who gasp when I use a saw or a grinder without safety glasses lol
He was holding his finger worryingly close to that hob while it was running.
I understand that there are many cost prohibitive constraints and some cultural differences when it comes to the prioritization of safety. But guys, you've got to include a chip breaker on that tooling (it only requires more labor, which if I understand correctly is not the limitation there). You can't be running a lathe if you don't have any fingers.
thank you
Excelente trabajo impresionante nivel experto mis respetos maestro
I love the vernier with the grads worn off!
cheap chinese calipers. the lines are laser etched really shallow. Not like good ones that are engraved and painted in. $10 for crap $200 for quality verniers.
Fascinating, thanks
Amigos, Ver esse vídeo é muito bom, vocês conseguem ensinar as pessoas varias técnicas de manutenção. parabéns!
kzhead.info/sun/ZM16ls6vb2RvZ2g/bejne.htmlsi=ytiSuvgL2Qj5bCmb
for the record this is made out of steel and not cast iron. first turning the shaft then hobbing the gear on a gear hobbing machine with a hob. by the looks of it the material is probably some quenched tempered AISI4142, tho it would really need that tooth hardening and grinding to work long lasting
Great skill,perfect machinist. You did the job very nicely. But safety of your body is first. Be careful to remove chips by hand.
Genius! That’s laying it on a bit thick mate, time to recalibrate your understanding of genius dude!
Lubricating oil at the end just come out of a Hino with its 20k mile oil change.
For the amount of expertise on behalf of the workers, I wonder what the U.S. Dollar equivalent would be so far as what was charged for this piece to be made? VERY nice job! Highly under appreciated in my opinion here in the United States with our throwaway society.
The average Pakistani Skilled machinist makes about $200 USD per YEAR! I don’t think you’d be willing to be poor just to say that you don’t live in a throwaway society. Besides, this extreme is unnecessary in a modern state where parts are in ready supply…
@@yamahajapan5351 I guess I did not clarify but the newer generation and other generations just buy new here in the U.S.A. as sometimes what needs to be fixed is just a small modification that costs ~$150 verses paying $1,200 for a new part. I am speaking in general terms not necessarily the part that was made in this video. Plus sometimes the parts are already obsolete due to limited shelf space.
@@jtg2737 well put point. I own an old truck. I've had to make many parts , cause parts are harder to find. So.....l fabricate whatever l need. The thing that bothers me is whenever l go to buy some part for my old truck(69) salesforce look at me like " there's no way bud too too old" , some mechanics won't even look at it. It's because there is more money to be made in all what's readily available. Very sad, sometimes even upsetting.
@@olblu8746 I'm willing to bet the majority of current crop mechanics wouldn't know how to adjust carbs, and set points, and do old school timing. Take it to a boat mechanic. I'd bet they'd have a look.
Yeah we throw it all away. Including this lathe he is working with. But we replace it with programmable machines that would do this part in about 20 minutes. Complete. Of course our throwing away as you call it, is melting it down to make 1000% better machines. Funny how media portrays north America to the world. But I give the guy credit, it looks like he is in a poor area and is working with what he has. Since India has a large and growing technical machining field, it's odd this man is not working at a shop with much more advanced machines. I am thankful for my early years on manual machines. But it is hard to compete against machines you can literally make dance.set up programming and tweaking a program to its optimal performance is pretty cool.
excellent helical gear making. I want to learn it
Getting it done, pretty cool really.
Great machining my only thing is the equipment being dirty and covered in metal shavings the machines should be cleaned of metal shavings and old cutting oils to keep them operating as efficient as possible but none the less great work
Some good skills there.

I learnt that an expert with a worn out lathe is better than a novice with a brand new one!
Nice work. Great team work. Thank you for sharing.
So rebar is now cast iron? Even though rebar is actually steel.
You spin one side perfectly smooth then you put that into the bit clutch and the entire process will have higher tolerances of accuracy...you must prep first befor you lathe...the end he put in the chuck bit was not perfectly even...always prep befor fastening in headstock chuck...
Thank God for British and American made machinery.

That’s a steel bar. Cast iron would produce powdery black chips.
😍😍👍👍
From the thumbnail and description it looked like the guy was going to do it all on the lathe.
The tooth profiles do not look anything alike. The teeth are going to grind and slide and heat up and wear out quite quickly. That is, even if the part is heat treated, which is unlikely.
It's useless if not heat treated, so why not just anneal & weld up the old one? Gotta be quicker & better then a probably unknown steel and you've got the old tooth profile to follow.
10 seconds in I can see what a genius he is facing a part 10 feet out of the chuck without a rest or center
as a machinist ive have never seen the last operation pretty sweet
thank you
You mean throwing it in the dirt?
I assume the next step is to get the new gears ground and hardened before it's put into service.
No way. Its used as is.

Excelente trabajo mis hermanos excelente video saludos cordiales desde Monterrey NL México 🇲🇽 y le mando su merecido like 👍👍
The first video where work was done with the correct tools...and then they dump the finished part in the dirt.
This is not Geniuses it’s a trade. It’s called Fitter and Turner or Fitter Machinist. Would you call a plumber or mechanic a genius if you had never seen one at work? Watching these guys work is quite scary. They put their fingers where they should never be put and they don’t wear safety glasses. By the way that is not cast iron. :)
You're very salty for no reason
@@Usmanthemecano I stand by my comment. It’s not genius and if my boss had of seen me put my fingers where those guys did he would have kicked me in the arse and said don’t come back. Other people should not watch this and think that clearing the swarf out of a keyway with your bare fingers while the machine is still running is a safe thing to do. Most people who do that are nick named Stumpy.
Thank you Davo, All this ingeniousness and expertise in trades is mostly rubbish because it all generally happens unseen and people with non type background have not a clue. Its why trades have 5 year apprenticeships and a certain level of education. Its what we are trained to do. There are many trades and skills that I admire their level of skill and expertise , but in the end its whats involved and expected in various trades. And as far as safety goes "whats that ?? " Unfortunately life is cheap in those countries and profits are marginal at best, so safety gear and training come down on the list of priorities. Sad but true
@@ScatManAust I’m an old Machinist and I still have 10 fingers but I know one false move and I could have them off. Safty boils down to not being lazy or not being trained. One skill i have learned over the years if you ever hear the little voice in your head say “I should be careful doing this” stop right there! You are about to stab your self with a screwdriver (for example) Maybe I should look up the definition on Genius 🤠
Incredible skills
Ok, but where is second part of production process? I mean thermal treatment like hardening, tempering...? What kind of steel was used?
Wow I am impressed. So many negative comments probably from people who have never owned a lathe never mind a gear hobber/shaper.
