I'd wager the only parts original in those machines would be the chassis. Everything else was probably replaced piecemeal over the course of the 70 years they've been in that shop.
Now I'm not a metal lathe worker. and only know what I saw on RU-vid of a lathe. But let me put it this way: I'm not really impressed. in fact I am thoroughly unimpressed.
Lost my comments. I was saying I learned on machinery of that era and eventually advanced to NC tape controlled K&T tool changers before I got fed up with the Union and left for the military. I can see many things that would make their jobs much easier and their tools last much longer but that is just me. I must say however these men do a great job working with what they have.
Those are some massive deep cuts for one pass and the swarf build-up around each machine is horrendous, but fair play they are giving a few more years life to whatever that pinion is out of.
Un professionnel de haut niveau, beaucoup d'expérience concernant ses travaux de tournage, d'alésage et j'en passe, mes respects Monsieur j'espère qu'on vous rémunère à la hauteur de votre travail je lève mes 2 pouces, encore merci pour votre vidéo ,vous êtes un exemple pour les jeunes tourneurs ; Mes respects Monsieur
I’m self employed semi-retired precision engineer and have used manual machinery for years. Because I was near to retiring it wasn’t worth me buying CNC machinery. It nice to see that some people are still doing things the way I’ve always done them. I’m appalled at their lack of safety equipment though. No safety shoes or eye protection is madness. One other point; the title says 100 years old technology. The principles might be old but the actual machines are at most 60 or 70 years old.
OSHA nightmare. Open toed shoes, no eye protection, loose clothing around machines and so on. Hence the older guy operating the shaper with half a thumb.
Craftsmen... turning out work much more accurate than the machines they are using. Health and Safety people would have a fit, but hey they get 'er done. The heat treat furnace is a doozy... and they seem to use the Mk1 eyeball for hardening temperature... oh... no... he has a remote pyrometer, and a hardness tester... cool... 🙂 I note in all of these videos that their tooling is shop made with brazed carbide tips, which would certainly save a lot of expense for folk who's currency is probably not that buoyant. Well done guys... great job.... even though it would give the average machinist in the West the willies, it works.
The machinists could not work around that problem. It was the piece that was cast and its circumference at the splash was less than the diameter that was per specifications. You can only take off material and not add it. Unless you weld extra at the splash to build it up. Evidently, at that splash, it did not interfere with the connecting pieces. I see some comments are critical but to me, these guys show years of experienced craftsmanship working in a country that does not have immense resources. I love to watch these clips showing different cultures.
These guys are doing amazing work despite the appalling work conditions. There is obvious pride in their work. Those without any knowledge ( YT seems to find them all) may view it as slapdash. That absence of younger workers is a worry. Every country that considers itself advanced in it''s manufacturing methods worked exactly like this only a few generations ago.
This kind of stuff is great for new metalworkers to see the basics of machining applied and in action at a very slow pace; its often difficult to see and understand whatva CNC macine is doing because if the speed. I love watching these people in poorer countries use creative ways and their ingenuity to make things like this.
lol if they go blind they end up jobless on the street which I would assume is only marginally worse than working under these conditions living in a mud hut.
I was taught many decades ago that really skilled people can make almost anything with basic tools, and I have found that to be true. I once made a complete telescopic sight base and rings for a rifle with just a hacksaw, pliers and files. I didn't have a vice, or even a pair of vice grips at the time, but I did have a small propane torch for the brazing. It turned out OK and worked well on a P14 303 rifle that I had at the time. That would have been in 1962 or so when I was living in a bed-sit in Auckland, NZ, so no workshop facilities at all. I was 20 then... It's amazing what you can do if you try. Happily, these days I have a decent lathe, mill, forge/anvil, welders, vices, measuring equipment etc. etc. ..... Sures does save time and it's so much easier to be really accurate... :-)
Exactly... machines make things, with the aid of craftsmen, more accurate than themselves, including other machines. The first lathes were crude 'dead centre' setups and were used to make the spindles for better ones, which were used to make accurate slides that led to mills and shapers..... Soft steel was case hardened for wear and hand fitted, enabling the machining of later alloy steels with high speed and latterly carbide tool bits. It's all a progression. The old cam operated automatic lathes have now given way to CNC with all of its speed and versatility......... But there's still room for the jobbing engineer that can make one of something to OEM specs when factory parts are not available. How many young folk today know how to forge and temper a leaf spring for an old gun? Not many I'd say from the people that come to me with long faces and broken old firearms... 🙂
And to think, this is the tooling, men and metals that built the industrialized world. Technology has been updated about 50 years . I wouldreally like to work in this shop for a year or so. With a pair of Red Wings on though. And a welding helmet.
I would love to know how close their apex measurement is on that double helical, because I have manufactured similar shafts like that (turn, hob, grind) with far more sophisticated machinery and I know that I had to have that apex measurement within a couple thousandths of an inch. I can't believe they can get that same kind of accuracy with the machinery they are using.
Se fabricam e pq funciona...eu tbm trabalho com usinagem e com máquinas modernas.....mas não duvido da qualidade do serviço deles por mais rústico q seja
O trabalho desses profissionais é brilhante e merecem todo nosso respeito. O que entristece é ver as condições insalubres nas quais trabalham. EPI' são perfeitamente dispensáveis. Níveis de ruídos baixíssimos, nada pode cair na cabeça e muito menos nos olhos deles, botas e luvas pra quê tbm não é verdade? Mangas compridas próximas de maquinas rotativas tbm não são problema. O trabalho final mereceu nota 1000.
E o tratamento térmico fake no final ? aquilo não foi uma cementação e nem mesmo uma têmpera, foi apenas para escurecer a superfície da peça e dara a impressão de que ela foi tratada corretamente.
Truly amazing skill and workmanship. Appalling safety standards! Baggy clothing, open shoes, no eye protection, no hearing protection, open moving machinery and belts ........
Vielen Dank für Ihren Respekt und Ihre Grüße aus Deutschland! Wir schätzen Ihre Unterstützung sehr. Greetings zurück an Sie und alle unsere Freunde in Deutschland! 🇩🇪👷♂️🛠️
Compared to this shop the few commercial American machine shops I ever set foot in were compulsively obsessed with cleanliness (chip removal) and unnecessarily high flows of coolant/cutting fluid. That the gear hobbing machine had a functional cutting fluid system surprised me. I expected an old man or a boy with a coke bottle. Where are the apprentices? I was under the impression that chip removal and dribbling cutting fluid was a prime purpose of machine shop apprentices.
believe it or not, some of these places are run by wealthy people ... they purchase all this old equipment for a cheap price and they hire these workers for a very low wage and have stuff made for them ... often the parts are then shipped over seas to suppliers. Just look at the lathes they are using, these workers right there have at least $50,000 dollars in equipment ... there is no way they would be able to afford that kind of money.
the work these blokes do would be absolute unacceptable on modern equipment. you see a bunch of hard working old men and think that just because they are hard working that they are skillful. no sir. i dont even operate gear cutters or lathes and i can point out tons of things that i would not allow to happen on my job.
OSHA would have a field day with all the violations in that factory, open toe shoes, loose fitting clothing, no eye protection, trip hazards everywhere, etc. However, they do some pretty damn good work in spite of all the hazards.
*Horror! The technology is like 80-100 years ago. The accuracy and purity of the processing remain a big question. There is no safety precautions at all stages of work.*
2:12 100 yo tech. except what really counts. Probably the only main difference between these machines and a modern one, is that new ones are digital, and have electric/hydraulic movement. This is all manual. 🤷♂
It is stunning that there are still workers being treated this poorly. PPE is not all that expensive. It is corporate abuse, plain and simple. The owners have no humanity. It is helpful that this channel demonstrates how cruel the world still is. American industry would be doing the same thing if they could. UNIONS stopped them!
You've raised an important point. Safety and fair treatment of workers should always be a priority. While our machinists might not have all the resources they deserve, they demonstrate resilience and skill in their craft. 🛠️💼 Let's continue advocating for better conditions for all workers! 💪🌟
@@user-mm1jh3bq6uStimmt, ich schaue mir immer diese Videos mit einem leichten Gruseln an. Wenn ich mir diese herunter gekommenen Werkstätten, den Umgang mit den Werkzeugmaschinen und Werkstücken weiß ich warum Pakistan zur dritten Welt zählt. Es nichts mit Geld, Technik oder Religion zu tun. Es es liegt an dem mangelnden Wille etwas „gut“ oder „besser“ zu machen. Alle sind zufrieden wenn es gerade so eben funktioniert. Weit kommt man so aber nicht und das erkennt man deutlich
checking the keyslot width with a caliper? this is critical. if too wide, the key will rock, and ruin the shaft. shoulld be a light press fit. i didnt see a dial indicator once in this vide ( although i fast forwarded and am open to be corrected). quality job 3 safety job 5.
I saw a similar lathe in Manila where it had been taken apart and had the carrier bearing hub bored out and replaced with the size they use on Mercedes Benz Heavy Trucks so they could pirate bearings out of the junkyard. and they made beautiful things.
Приходили боги и приносили новые станки и инструменты. Делали приспособления. Научили работать с клиентами и зарабатывать деньги. А потом умерли. Бедные остались одни. Деградировали и приспосабливались как могли. И не было ни сил, ни желания уйти в сторону, откуда приходили учителя! Но жизнь текла, железный дом давал пищу, а развитие только могло отнимать спокойствие. Так они и жили и было им хорошо.
