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.
@@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.
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.
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.
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.
@@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.
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.
Thanks hydroman99 ! I don't want to watch the video but wanted to make sure someone pointed out that "Mechanical Skills" is a RU-vid "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 RU-vid. I just wish those who choose to do so would have enough self respect to teach the correct science (metallurgy in this case).
@@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 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 -
@@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.
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.
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.
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.
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!
@@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)
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.
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.
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.
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.
Да ну ты это, не напрягай, у этих уже индикатор есть, ваще модные черти, другие вон по проволочке биение заготовки выставляют. А дальше глядишь и до закалки дойдут.))))
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.
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
Jaki z niego geniusz jak nie potrafi naostrzyć noża żeby łamał wióry.Sam kiedyś zginie od wstążkowego wióra.Pół wieku temu w Rosji była stosowana w obróbce tokarskiej metoda szybkościowej obróbki zwana metodą Stachanowa , ale skończyła się kilkoma trupami i rozwaleniem tokarek. Myślałem , że to już się skonczyło , ale widzę , że jeszcze niedouczeni tokarze to próbują i walczą z wiórami. Do tego materiał jest z zupełnie innej bajki.Kawałek złomu z niskiej jakości stali.
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.
Am not a machinest.....just observing how man can come up with methods to mold the surroudnings. I wish I would have access to such tools & equipment. Looks beautiful like a piece of art.
неплохо,а у меня ума не хватает косозубку рассчитать в уме. гитара дифференциала сложновато считается,зато сыну объяснил зачем синусы учить надо и дроби 😊
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. :)
@@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 🤠
This guys got some very creative way of thinking but man does his house keeping skills leave one to question weather his laziness is not worth the talent !
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
