I was impressed at how true the rough casting was even before being machined. I love that lathe. The ratchet feed is classic stuff. The bore must be tapered as the machinist did a fit check with what appeared to be a QD type bushing. It amazes me that they have this machinery but lack precision measuring instruments. I guess you develop skills over time that get you close enough. I was blessed to have worked in the tool and die trade where I had instruments that allowed me to easily worked to tolerances down to .0001". That was many years ago. All in all, the men in this video are very skilled and have my total respect.
Чем вы измеряли допуск .0001?
Meanwhile these guys have made their own tools that get them within .01" all day ;) :)
Gotta love the no dial gauge way of dialing in.
Their precision measuring instruments were probably ruined from lack of care and sufficient abuse long ago.
Very friggin' impressive. Looks like it's been done the same way for a 100 years and it works! Thanks for showing us.
Amazing work man. People say that old tools wear out but they really don't if you keep them oiled and treat them decently. Those tools appear to be from maybe the 1950s or the 1960s and they do a fine job maybe not as fast as the new ones but they're paid for and they work and they work and they work and that's all that matters. My lathe is a South Bend from 1930s and I'm happy with it. I don't use it a lot but when I need it it's there. I like old stuff! It makes me feel comfortable because I'm old stuff too and I don't want to be thrown out as well.
Older tools were built without the idea of "Planned Failure". If maintained properly, they last for a long, long time, with only the occasional sacrificial bushing/bearing needing replacement.
Modern stuff is designed with a much shorter lifespan in mind. Really shitty companies will even engineer failure in--like using a plastic bushing in a sealed unit that will eventually fail, resulting in severe damage to other key pieces and necessitate complete replacement.
I’m actually impressed. Everyone was wearing actual shoes, workers were wearing safety glasses, the machinist was taking care to cover the ways of his machine to protect them from cast iron dust, all the machines were in an actual building. Worlds better than most similar videos I’ve seen.
Not everyone was wearing PPE, there was a worker wearing thongs. The shoes worn by the others were not steel capped safety boots. Those long shirts could easily get caught in rotating machinery and pull the wearer into the machine.
Sarcasm ??
@@frontrunner3052 not at all. Watch some of the other videos like this. Machines in the street, gouges in the ways, everyone wearing loose flappy clothing and sandals. Doesn’t meet a lot of modern safety standards but so much better than the others by comparison.
It's probably Turkey.
Yeah, they had their sleeves rolled up and safety squints, but the lack of steel toes was really unnerving.
It's really sad, these guys are incredibly talented; how many competent machinists get injured/killed every year because of the lack of safety regs? The company owners are raking in money hand over fist, they could easily afford to equip them with basic PPE, but these guys are viewed as expendable, even though their skill and experience are massively valuable. Shortsighted, to say the least.
Have to say the workshop looks like a museum time capsule from the industrial revolution complete with work and safety practices to match. I love the footwear while handling large lumps of cast iron
Is it fool-proof? No. But does it make people think about the consequences of their actions? For sure. When I watch the fail videos of our Western highly regulated plants and workshops I wonder how quickly our morons and distracted slackers would be dead in a factory like this one.
Or how quickly would their brains evolve to think about every move and every step they make...
@@RadekPogoda Yes there is a place for scrapping all safety rules and letting Darwin take his course. In the words of peanut stupid should be painful
What’s wrong with long baggy clothing and flip flops?
@@donniecreasey7722 Nothing at all if you dont mind being rapped around fast moving machinery or losing the odd toe or two
Indeed, those are the best toe-tector flip flops I have ever seen.
Just as a matter of interest, I started work as an apprentice machinist in 1962 in a factory in West Yorkshire, UK, and the lathes, planers, and drills were easily more ancient than these guys are using. And for sizing we only had rulers and spring calipers!
It only takes a day or two to get a feel for making parts fit - not necessarily to what the drawings said the size should be.
The machine shop had line shafting driven by a big single cylinder diesel engine.
When the place shut down it would have made a perfect industrial museum but there were so many similar shutting down in the 7-80s that everything went for scrap.
That those functional lathes got chopped up and melted down in furnaces somewhere is sad in many ways. They could've continued to produce useful repairs on earth-moving and mining equipment with some modern adaptations as demonstrated by Kurtis and Karen in QLD's *Cutting Edge Engineering* Channel.
The Pakistani attitude of _"make do with what's available"_ is admirable in my opinion, and I built my own house 35 years ago with the same approach and eliminated the _Mortgage Millstone_ around my neck 😀
ive been in a tool shop for 8 years now. i got a v block from an retired friend that he gotten from a retired friend. it dated from 66. i really like the thought of it going to someone else after me. and im 40 so ill have it for a while to come.
@@chrisruiz1065 I know the feeling....my dear friend JJ just passed away, he gave or sold several of his tools I really treasure them bc they were his.
I still use a large lathe once used in WW1 manufacturing. It makes me happy using such an old thing.
Don't worry a lot of the old British machines ended up in India and Pakistan. They l9ve the old British machines. Will last 100 years not like the Chinese stuff. My old Colchester was built in 1964 and can still hold a micron on a good day.
Молодец!!! А баня, да ещё и своими руками сделанная вообще круто!!!
Fine machining and filming and editing job! Thanks for sharing!
Неплохо, весьма неплохо! Молодцы ребята! Учитывая то, что вы работаете на оборудовании сто летней давности, так вообще шикарно!
25:44 - бедная фреза "насухо" грызет (пусть чугуний, но ну и что?) и уже почти половины зубьев унее нет.
@@ajdarseidzade688 Как и точение на обратном ходу в начале видео . Того и гляди резцедержатель отлетит нах .
@@НашСемейников Точно. Даже не обратил внимания на это. И это все не "придирки" тут.
Интересно как они отцентровать смогли эту деталь , ощущение что она овальная как яйцо 🥚 а не круглая ⭕️
У нас и такого оборудования нет, всё вывезено металлоломом в Китай.
As India's Health and Safety Officer, I do approve of the safety sandals and clothing. Why can't Britain be like this? If the UK paid half of these men's wages, we could undercut them and make Britain great again.
Keeps his machine and tools clean, wiping down before setup and after machining.
keeping them in rust and torturing them without proper maintance.
With the amount of sand still attached to the casting, it is either constant cleaning and rags to cover the slideways or have silica sand get embedded in the guides scoring everything up.
I wouldn't let a casting near a machine of mine without at least getting shot blasted. I'm sure they don't ceramic coat their sand moulds either to stop sand fusing into the metal.
Special training really shines through on specific disciplines in this video.
For example:
Precision tolerance training at 16:20
Safety First (jump training) at 18:57
Understand the effect of harmonic loading and machine flex at 25:00
In appreciation of fine machine work from Germany, Pakistan has incorporated their own standard ... "goot-e-nuff".
Thanks Kevin sellsit
those machines are from ages when maria terezia was young. the difference is that they are now powered with electromotors and not steam :D
В этом видео действительно просвечивает специальная подготовка по конкретным дисциплинам.
Например:
Тренировка точной толерантности в 16:20
Безопасность прежде всего (тренировка прыжков) в 18:57
Понять эффект гармонической нагрузки и изгиба машины в 25:00.
В знак признательности за прекрасную машинную работу из Германии Пакистан ввел свой собственный стандарт ... «гут-э-нафф».
I'm honestly impressed that there were as many people were wearing safety glasses as there were. I'm noticing that it's mostly the older guys. I wonder if there's a correlation, there...
@@AnatolZelenkoff Thank you for the translation.
No lubricant and no keyway? Good video
Hello P T people. Always hard at work, good business you have there. Ok, what the heck was the guy on the phone while operating the overhead crane? This while the old machinist was fighting the two ton bull wheel into place. Phone guy would be gone from any other shop. Loved the set up on the huge vertical lathe. Seemed plenty solid enough. Your spacers on the flat gear cutting phase might be an issue, the work tries to walk away from the cutter if you don’t use a one piece spacer. Looks like the 400 ft lbs on the big hold down nut was sufficient to fix that. Nice job! Be nice to see the gear tooth hardening steps. Good luck from Canada.
انتم في بلاد الغرب تحبون العمل ..
أعتقدت انكم ستسخرون من عملهم هذا و تصفونه بالبدائي ..!
Owner's Son, pesume finger on the cutting was this, nice manicured nail!
In so many ways I find these videos fascinating. Usable products are made by machines that are a hundred years old.
I can only imagine and hope that Pakistan start to require schooling for all children and invest in technology that that is newer and up to world engineering standards.
Unfortunately with the current leadership Tribal System this will not happen for many years. Your nation is technology frozen in the past.
Aap zabardast engineer hain hamain aap pe fakhar hay
Shukria sir
I'm impressed, that lathe is amazing as well :) I've cut some gears before but that cutter is suffering a bit more than it should.
Great video.I really enjoyed watching it.
I like !
would be cool to see these big wheels being cast
As a degreed manufacturing engineer I find this an excellent illustration of fundamental engineering principles, datum, concentricity, etc. The best educational material I have seen is the Springfield Armory in Massachusetts. Firearm manufacturing is the birthplace of modern machining includig what you see here.
That is the first engine lathe that I have ever seen with a ratchet dog feed on the cross slide and carriage. It may have come from Britain to be run on a steam powered line shaft. The VTL “ attachment hanging from the wall was likely engineered from a local shop.
No, boys and girls, this is not the typical machine shop that your folks worry about.
I took notice of that as well. When I was a machinist back in the late 1970's I occasionally ran a shaper that had a similar ratchet feed mechanism. I loved running that machine because it was so mechanical.
I was thinking all the while what is that thing going up and down.
It is possible to manufacture parts with unlimited precision with "simple" tools, a brain and hands. Here we have roughing, at the other end scratching. Thank you so much for this empowering video. No limit.
AMAZING WORKMANSHIP THANKS FROM THE USA🇺🇸
Brilliant to see those old British machines still doing great work. Pleasure watching this.
now this is the difference between a machinist and a cnc operator
RESPECT, FOR MY BROTHER MACHINISTS FROM USA!!
A GOOD DAY OF WORK!!
👍👍
OMG They "Indicate" center using a Bent Surface Gauge with a Pointer !! Love It !!
Nice anchors for small ships.
Nice video. Very safe work. 19:20 the man phoning during the manipulation. Very safe. Final accuracy of product less than +/- 10 mills. Excellent.
Thanks
10mils? More like an inch. Everything is off
Thats great work. What does the gear go on ?
Well done! Best of luck!
I used to work at a company that produced gears for the printing industry. Among things that we did was repair of what were called "bull gears" with broken or worn out teeth. These gears were the main gear that drove the plate cylinders on multi-color presses. We took the old gear, turned the teeth off of it and then machined a steel ring that was heated and shrunk onto the existing hub and further pinned into place then machined to final dimensions. Some of these rings a 6 foot tall person could easily stand up inside of. All machining was done on manual vertical turret lathes and new teeth were cut on vertical hobbing machines. All this produced gears with a tolerance of less than .002 inches of run out and diameter. Nothing new in this video to me. LOL.
Sounds like a railroad steel tire.
Twenty-five years ago, I was buying custom gears of similar sizes from United Engineering and Foundry in Ohio, for use on the chain-driven asphalt plant elevators we built. UEF poured the sand cast rough blanks, then machined the teeth and hubs to accommodate TL or QD bushings as required. UEF also supplied large multi-groove sheaves in the 24" to 36" OD range - larger than the stuff we could order from Dodge/Motion Industries. UEF's plant was only a little more "modern" than what we see in this video.
NICE. VERY NICE. ANALOGIC METHOD. OLD SCHOOL!!!!
Very interesting how old machinery has outlasted a couple of generations of operators and still turning out good work.
congratulations! it's amazing to see them work with old machine
Absolutely amazed watching 👀 !
I love the shop. These guys are 1st class. The camera work was outstanding!
Now THAT'S a lathe!!
Some good filming skills going on here. Well done.
Thanks
This type of work builds the country
How many days were spent making the one large gear? Thanks for sharing.
Every time I see a huge metal part I say to myself "certainly there can't be a machine big enough on that scale to machine it".
Well, I'll be dang! There is huge machining equipment out there!
Wow, imagine how big the wrist watch must be! 😲🤓
G’day and greetings from Tasmania Australia 🇦🇺 I’ve been watching how they machined this large wheel they have it down pat and with not much gear, their tooling is a cutting piece brazed on a bit of round steel. Thanks John
Практически "на коленках". Молодцы.
Incredible work, amazing.
Их измерительные инструменты-это просто отпад с истерикой.
это называется "на глаз" или "по месту".
Особенно если измерять ширину зуба пальцем .
Good machine operators. I wonder they never used a sleeve to squarely locate the hub onto the mandrel?
Thanks for this. 👍

amazing video skilled judgment for sizes
استاذ ومهندس بمعنى الكلمه اسال الله له التوفيق
شکراً
Safety shoes - safety glass, butb outstanding job for what you started with. No union ship, I guess.
Fascinating to watch. India, Pakistan???
Pakistan
was he squirting water on it for lube? is that orange stuff just rust? no lube on the gear cutter either?
Interesting video, though they are using very old technique, not efficient in modern days.
got to hand it to these guys nothing they cant do i started my engineering apprentiship in 1959 it takes me back By the way is that Jack from the Rovers Return
Awesome Raheem Gull Sahib
Love those sandal style safety shoes!
I am impressed that with an extremely rough casting and worn tooling, lack of precision instruments and minimal energy expended that this part came out as well as it did. The machinery this part is used in must be quite "loose" and require prodigious amounts of lubrication to survive. That being said, if it works, it works. The cost of this part and further replacements as it and associated parts wear out is most likely less than a "proper" commercially produced part.
My thoughts exactly.
That thing is so big it's going to grow .001" for each 1.5C rise in temperature. The guy truing it on the gear hob should be easily able to see much less then that with the rig he's got. You'd be surprised how accurate you can be by eye, given the right conditions.
Was that gear blank pulled from the bottom of the ocean?
These are the best type of jobs, you start with nothing and you end up with a finish product that creates a profit. I s called, PRODUCTION.
I know nothing about lathe machines, but why don't they have to cool the tool with oil or something?
Это всё здорово, интересно какие у них допуски +_ 1 мм?
tolerances? fine thanks...
Good working
Wow, this is going to be a big clock ! ⚙🕰😁
Impressionner la fraise mère, il lui manque la moitié de ses dents, faudrait que je partage ça avec mes collègues, ils seraient scotché.
Respect pour ces usineurs qui travaillent avec des antiquités de musé.
safety glasses? i'm impressed! and i threw out my dial indicator and made a wire indicator like these guys use. hey, we aren't sending this gear to the moon.
Real hard work. Much appreciated.
Hard - for sure. But smart and with huge experience visible in every move.
Fantastic!
Thank you
Great use of limited technology
Best Wishes Always from Delhi India
💐💐👍👍👌👌🇮🇳 🇮🇳💐💐
Thanks ❤️
Are you working with cast iron or a steel alloy ?
SO...!! Who made the first machines to made the second machines..??
What's the gear for???
For a man of his age he copes quite well with the heavy hard graft in machining these large very rough castings. If those making the castings took a littl more care his job would be just that more comfortable for him.
Man of his age? He's probably in his 30's.
True skill, craftsmanship, Even using old clapped out gear, a true artist can turn out a "masterpiece" Well done sir!
Not to nitpick but some of the casting flashing could be removed from the spokes.
I would assume that the spokes will be cleaned up at a later stage of the fabrication process - no end customer would accept the product with the spokes looking that scruffy. It makes sense to do most of the machining first, then final finishing of the spokes and other non-machined surfaces later: that way, if a serious flaw, to big to be repaired, is found in the casting while machining the gear teeth, the effort, time, and cost that would have been spent on cleaning off the flashing wasn't wasted.
Such a great energy to get this job done....but safety should be taken seriously
Great video reminds me of my work at the Machine Works in PR for sugar mill parts back in 1960!
I'm wondering why the cast is so scary. Could save so much machining with nicer casts. Love these vids.
Love and support from virginia d bqutista
I LIKED THE WORK. YOU WORK WELL WITH THE EQUIPMENT YOU HAVE , THOUGH A BIT DATED, KEEP UP THE GOOD WORK. I WONDER WHAT THE PRICE OF THE GEARS COST, NO DOUBT MUCH MORE IF MADE IN AMERICA.
Don't think made in Any Western country!
Weldon Ustad gee
I would order mine with polished spokes!!
An original Wilkerson lathe?
make a tripod for your camera
Great working,and accomplishment. 'yet that buildings walls look like 1 brick thick' yikes'
"Amazing". That's one word for it.
MAASALLAH MAASALLAH SÜPHANALLAH ALLAHUEKBER ❤❤❤
Love pakistan 💝💋💞💓💗
Thanks
I served my time as a gear cutter, All I can say is there's a reason why English gears are the best in the world , that said it seems I wasted loads of time being trained in metallurgy ,quality control and machining ,when all along I could of winged it like this lot , looks like they're using English machines though ,your welcome.
I wish i could "wing it" any way near as these guys!
Mesmerizing!
Maaşallah, maaşallah.👏👏👏
never seen an auto feed mechanism like that,very cool
جيد جدا تحيه من العراق 👌
Um grande abraço da qui Brasil
If you can make those cog wheels then you can rebuild that machinery, so as long as there is a demand this workshop is pretty much a permanancy!
Can't believe how this turns out and likely very useable for low speed application. But that casting was so rough that the machinist sure had a challenge to get it in finished form. We have a antique machine that needs a large gear made as the original has been taken and we have to come up with a replacement. The Dia is 44.5 in and 5.75 wide at the face. 66 tooth, about twice the pitch in the video. And lastly not priced for sale to the Rockefellers! any ideas?
Contact David Brown Gears, Huddersfield, UK.
If you are located in USA contact Spencer-Pettus Machine in Gastonia, NC. That size is a piece of cake for them.
Good job👍🏻👍🏻💪🏻
Looks like something out a Dickens novel. At least they have safety glasses.
