We Make A Big Helical gear from the High strength parts of old Ships

- Gears can be manufactured by a variety of processes, including casting, forging, extrusion, powder metallurgy, and blanking. As a general rule, however, machining is applied to achieve the final dimensions, shape and surface finish in the gear.#gear a nufacturing#manufacturing #gear #helicalgear #australianmachinist #machineshop #pakistanitruck #oldship #ships
My second machining job, I turned giant castings on a lathe right from the foundry still hot and smoking.
Then by the time you finish turning them hours later, the are barely warm anymore.
Hours and hours of patiently staring at a slowly turning part.
I think we machinists could watch paint dry and be satisfied by the slow inexorable progression unfolding realtime.
In this case I feel a bit sad for the tortured lathe, they are roughing pretty hard early on. Lots of chatter. Then they use a sledge hammer to center the piece in the gear cutter. After this they lift it with a couple of c-claps between the gear teeth. Looking closely, pretty much every tooth has a chunk missing a 3rd of the way down from imperfections in the casting. Then they roll it through the dirt, smack it against a metal table, and finally it's ready for shipping on the back of a motorbike or something :-) Just a little more kindness and attention to detail, these guys would be capable of amazing work. I guess near enough is good enough.
@@nohandleleft To be fair they are doing all of that work with British Raj era machinery.
WOW!!! really WOW SKILLS.....no heads or tail.......just some machining operation on at least a 100 year old machine
Why would anyone want to use a boring bar to turn the OD of a piece? Terrible finishes inside and out.
I'm pretty sure the OD flats of a gear don't need to have a mirror finish.
Because the job is too big for the cross slide to go past it. The poor finish is mostly because they used a sharp pointed tool of the sort normally used to cut threads, and partly because it is poor quality steel.
@@xtnuser5338 : Especially when you roll the finished gear in the dirt covering the concrete floor.
@@keithammleter3824 My point is that it wouldn't make any difference in the gear's performance for the outside flats to be roughed up. They don't touch anything, and for a gear that large, probably turning at a relatively low rpm, any slight imbalance caused by nicks/dings wouldn't be worth worrying about.
@@xtnuser5338 I agree.
ALMOST HURTS TO WATCH THIS.... THE PIECES ARE SO ROUGH
Buen trabajo!
Good job!
Gotta love them safety flip flops LOL
why would they even make this
Because some other big piece of machinery needs it?
It's really sad to see that they do a nice piece of hardware then they just roll out in dirt and mess instead of using something to carry it.
I park my ship for 2 days and some guy comes along and makes machine parts from it. Can't have shit these days...
So they take their precision part that took two full days to make and remove it from the machine with two large C Clamps and run the screw into the fresh gears. That mark is where the wearing will begin. Then they roll it around on their filthy floor. Whatever precision they had was lost as soon as it was removed from the lathe.
That’s what I was thinking to! No heat treatment! Rollin on the filthy floor ! The precision is long gone when it reaches the customer!
Yep, I guess it's made of tissue paper.... Next step is heat treat, right?
and i made a coffee table from a cable spool. just like these dudes i'm pretty proud of myself. well, actually, i just rolled a wooden cable spool into my living room because i needed an end table for my couch

Wouldn't be hard to put some holes in for lifting eyes or similar.
They need to fabricate shovels and brooms to clean the shop.
Cheval Bleu was built in 1995, and already being chopped up?
Yeah, I looked it up, best I can tell is the big oil tankers don't last that long, and she's 28 years old. Some only lasted 10.

А я всегда думал, где они так свободно берут толстый металл и крупные заготовки. Корабли разбирают.
Почитал про разбор кораблей, там целые пляжи используются как свалки. Старый корабль с разгону врезается в берег- кто не убежал, того и проблемы. Ну а после люди с автогенами режут корабли. Это целая индустрия, одни только цветниной занимаются, другие гсм, третьи листовым металлом.
hoisting a 500lb chunk of steel by c clamps while wearing sandals, what could go wrong.......
It's more like 3 tonnes.
Its incredible how they have such large and expensive pieces to work with and yet such crude tools and poor skills.
They have a sizable crawler crane and yet they don't even have a ladder to get inside the ship, it really doesn't make a lot of sense.
They have a big lathe but they apparently cut the wrong angles onto the cutting tool and use no coolant, rather than cutting all that rubbish off with an oxy torch they abuse their tools and time with a long interrupted cut.
I'm no expert machinist but I know enough to know what I'm looking at is really not that great.
Never forget they are illiteral idiots in one of the nastiest 3. world shithole.
No safety shoes were harmed during this process...^^
I was disappointed when I realized that the work piece was nowhere near the size of the click bait thumbnail until it became obvious didn't want to watch any more of them wearing down a piece of old boat .
No not very interesting, they don't use inserts on their cutting tools(what 30 yrs. behind?) why spend all that time machining if it's the WRONG alloy for gears? It is or it isn't forget skill.
Why do workers in India wear slippers or open toe shoes . Protect your feet people
this is pakistan
я не удивился бы , если на заднее сиденье скутера и вперёд на закалку .
21:50 Reminds me of my ex-gf 😁
Судя по прогоревшему костру в самом конце ролика - не иначе как на термическую закалку откатили шестерню )
Grabbing razor sharp chips off a running lathe is a great way to loose fingers
"Lose"
@@stevo184 aw heck! You will likely “lose” a finger when it flys across the room and you can’t find it. Your fingers will be “loose” when they are no longer attached and in the bottom of the chip pan!
@@tomwilhelm67 where you get that emoji

Why all these videos are short of one or two minutes at the end which would show what is the final step and destination of the product we watch for half an hour or so!!

So they can turn a heat exchanger into a solid steel spiral cut gear?
Guys, you can use grinders on a lathe. Grinding discs are cheaper and faster than steel cutting tools. If you're using a lathe, just mount an angle grinder on an arm and spin away. It's helped our shop a lot. Just don't use belts. Very expensive. This isn't for precision work, just roughing out big gouges and uneven surfaces like in the beginning.
I think this film was made 100 years ago

Omg great job been done very impressed with your work team so respect hard working people of pakistan weldone. Love from UK
that steel looks machines like pig iron pure muck steel
It's hilarious how everything in this videos just ends up on the filthy dirt floor
Hours/days of hard work.
Just thrown on the floor.
🫤
It's so another guy/kid can earn something for cleaning it!
So glad I don’t live and work like this. Just screams poverty
Safety condition zero.
Why don’t they just put it in their 15 million dollar CNC machine?
Wonder how much workman comp will pay for a worker that gets hurt on the job there?
Then you roll it around in the dirt ,
banging on with hammer hmmmmmm not good
😘😘👍👍
Great safety footwear, open toed sandles.
Man certainly knows how to grind a HSS tool bit!
Its a miracle that anything in this shop works at all😮
this one is quite well equipped
Looks like everything has " Toothache" aka worn out and loose.
I wonder if that is an old Monarch lathe.
Not knowing too much about lathes, when I read your comment I thought you were referring to it being installed during the British Raj era when the Monarchy ruled India, until I remembered that Monarch is a lathe manufacturer... but now that I think about it even more, we're both probably right.
I know that the conditions and health/safety are severely lacking but as with everything we have to start somewhere. These guys can’t afford the latest, greatest 21st century tools/conditions so they do the best they can with what they have and know. It’s easy for us in the modern world that have grown up using the latest of everything to forget where it all started. I, like us all, am astounded by how these people achieve what they do in the conditions and with the old tools but I am also amazed by their determination.
I think they are afraid to evolve in using better techniques and tools and safety gear
All I can say is toes must be able to regenerate there.
What is the warranty period for this repair?
soon as it hit the dirt
What do you dopes see around 23:11 mins?
Watching this video in 2023; but TIME still stuck back 20th Century; to my astonishment these machines still work with Barefoot and Bare hand gloves with impunity only in Pakistan whose economy reeling through massive debt. It Mircle to see these Machine still work

😃😃😃
I'm curious. how they inspected this to make sure they had the correct pitch diameter.
lol
experience
That poor old hard working hob - did the job!
No quality inspection required 😁👍
Excellent work. Very strange voices.
Would that lathe cutter be something like tungsten carbine because it is stunning what it can deal with.
HSS (High Strength Steel)
tungsten fucking what now?
@@butchhastings2945 HSS is >>>
High Speed Steel. heres a chart. Hss can take abuse. Carbide will chip on interrupted cuts from the constant banging.
www.sandvik.coromant.com/en-gb/knowledge/materials/cutting-tool-materials
@@butchhastings2945 close! High speed steel
yeah, that's most propably HSS. A tungsten carbide bar of that size would be worth as much as that whole lathe lol. Most carbide tools only have the cutting edge either brazed onto a piece of steel or are a holder for carbide inserts.
I love the safety-gear!
Life must be cheap.
One of the most impressive Pakistani videos that I have ever seen 👏👏
Correct me pls, is that lathe spinning at the right rpm?
looks like they are using HSS, so the rpm should be ok. But even with Carbidetooling the rpm would look kinda slow at these bid diameters
@@W4LNUSS thanks mate.
I think they could go faster but considering they don’t have any coolingfluid this will do.
It is speeded up considerably based on the distorted audio.
He’s wrong, no, this is too slow
No coolant/lubricant?
Aluminum part.
See that brown liquid running down over the hob and the gear? That's cutting fluid.
@@pondartinc4002 No, some sort of poor quality steel.
