@@doggfriendly "master"

Education is the main factor in under developed country if they had opportunity to learn using modern machine tools they can also perform more better... but they learn by practice In this kind of shop .

There are two key pieces of machinery here, the horizontal mill and the dividing head. The 4th axis on the mill is useful, but you can actually bolt the dividing head to the bed to get that angle. This is the heart of a hobbing machine. The cutter can be shop made to the shape of the tooth. But this is just basic hobbing. The real problem here is that they are using aluminum for the gear, that will not wear well and so this is at best a quick fix that will need later replacement.

Rip bro

This is the first time i saw that they use a caliper

"I heard from someone in the old days...." Yeah, that's how a lot of BS starts out. These guys are using some clapped out machines and bowlegged calipers. I'm sure they could build a Space Shuttle in two days. Yep.

@@dcw56 It's sad you take that view. Well, without intending any disrespect to you, I suppose you work or have access to machining centres that cost millions of dollars? But these guys get the job done and manage to repair stuff.. NO BS THERE..

@@camiemengineer Pakistan did manage to build their own nukes (they are a nuclear power) back in the 1970s. Now... I don't think this guy or these machines were used to build them. Well maybe when that mill was new it was used in their arms industry. That said the old bronze worm gear still looks better than that "new" light alloy one he just made.

@@utidjian I am not suggesting that Pakistan does not have state-of-the-art machining centres. But there are many, (or so it seems), family businesses that have to make a living with old equipment, because they cannot afford to replace with new machines.

Its down to economics. The part was made from the money they got and probably thats all a person repairing it could afford.

@@soni204 Sheer stupidity then. Buy a cheap grade of steel like 1018 or 12L14. It's cheap and you can oil quench without spending the money for heat treating. At least then you have a chance with the new part. It will take longer to machine but won't fail right away. There is NO chance with the aluminum and to say "what they can afford" is just ridiculous.

@@sndnmytrnks I am a tool and die maker with My own cnc shop. You cannot check precision bores with an beat up caliper. For all those who think this is great work, Wait till the customer tries to fit it to the the shaft and its just a few thousandths small, then what? and i think thats cast aluminum. You couldnt pick a worse material for longevity

Does anyone else think this guy needs some safety glasses on?

Came here to say the same thing about the aluminum

thats back when things were made to last! not like today... serious skills there to make gears like that at the best of times.

*_As another great example, of which, around the globe, there are many:_* go to Cuba ... where the Great Majority of Autos are from the USA ... generally of vintages starting from the 1940s through the 1960s; where some are a hodge-podge of various hand-made mixed and matched parts but MANY of them look NEAR NEW!

not really its been my experience older machines were designed with service and wear in mind unlike today where things break right after the warentee expires. and at 70 yr old i would hope the machinists knowledge and experience are equal to the task of reproducing a part from a worn example. personally i wonder about the metallurgy and was the gear hardened because no matter how perfect the size and shape is it would be useless if it were not the right rockwell !

I think that comment was over the heads of most ppl....

Ironic that Leicester has more Pakistanis in it now than Islamabad.

No, I'm sorry to sound like a bad person, but these men only know what they have been taught, and their education is severely lacking. Using that aluminum skew gear in place of a bronze gear will result in a VERY premature failure of the part, AND the adjacent running gears. That is not a good repair for the return on the time. IF they know how to do it right in the first place, then why not DO IT RIGHT? If they don't know how to do it right, then why crow about this video? Either way, the part is far sub-standard and it is the weak link in the gear train which can cause total failure of the entire train of gear driven shafts. There is a point where "cheap" no matter how costly a proper part costs, is not cheap at all, but costs multiple values in dollar amounts. Do it right the first time and get the job done properly, even if it costs the equipment owner from putting more dingle balls and fancy painting on their vehicles. (Have you seen the decorations on their hauling and excavation equipment? Save that artwork money and do a proper job of repairs.) I know! That sounds mean. It is economics!

@@dcw56 Agree 💯 that part will break... No other way around it... Cheap material

@@dcw56 Surely the intention here is to make a mould? I mean that would make a lot more sense that people who are much more experienced and knowledgeable than [a commenter on KZfaq who pumps up their own ego by pretending to be a lot more of an expert in something that they know nothing about, i.e. you] would know more than you. Even the most basic engineer would understand that an aluminium part would fail almost immediately. On the other hand, trying to directly machine brass would probably be quite difficult. So I imagine, Mr. Expert, that the intention here is to use the aluminium part to create a mould or former into which they will cast a bronze part. And although I am not a mechanical engineer or a machinist, I have sufficient education to draw this conclusion. Which suggests that it is you, personally, who is lacking the required education to be an effective participant in this technology driven world. So go boil an egg.

@@DinoDiniProductions You need to return to school yourself.. learn how to make a proper part...

In the country Chile did that to, is called 'alive human treasure'

And guess what: Don't even think about retiring in the US. - I never worked so hard since I retired. The wokies convinced the kids they had to go to collage for 10 years and get advanced degrees in tings like urban studies and diversity. They ridiculed anybody who wanted to get into the skilled trades - Now there is nobody to replace us (And trust me, CNC is NOT the answer to everything, ) Now us old timers keep getting offers we can[t refuse to come in and do a job or repair a machine because we are the onoy ones that can get the jon done,,,,,but we are dying off ann when we are gone, the skills will be gone with us.

@@mathewmolk2089 I'm a US citizen and retired. I was a fine art photography and art teacher in a public school. I worked for 21 years in NY, which provided a pension of about $2200 a month That, together with our Social Security checks, and sales of a few pictures gives us about $5000 a month, which is enough to pay the mortgage on our new house, which we put 50% toward. Anyway, we have fully paid health insurance courtesy of the school district too, no debt, and are getting by. The pension was a life saver. At the end of my career, I told every kid who would listen, to go for a job with a pension. Most didn't listen and wanted to get rich. They will do what they do. As far as skills being lost. That is a major problem. Someday, many will wake up and think, I'm going back to school to be a machinist, a welder, an electrician, a cabinetmaker, or some other trade that pays very good money because no one is left. That is when there will be a rebirth of trades, but I think it is still far off. Now, they want to be Taylor Swift or some other musical star. She is going to make $600 million just from her concert tour next year. She will become a billionaire. Can you blame them? It won't work out for 99.999% though. then they will have to do something that pays the bills, like me. I was fortunate to have a teaching certificate in addition to my major in art. All the best to you. I do not know what we would do if we only had Social Security. I know it would be a miserable life.

I’m in the same boat. Older machinist looking to retire. I’m not sure my employer will be able to find a replacement for me. I feel guilty. There just aren’t any skilled machinists. I don’t think "woke" had anything to do with it. The unions got busted in the 80’s, all the apprenticeships went with them, and they started sending all the jobs to China. It was all the baby boomers that wanted their kids to go to college. I do prototyping for a company and the young engineers I see now who grew up with 3d printers and went to STEM and STEAM programs are going to do great things. They don’t know shit about machining, but I’ve worked with a lot of engineers that didn’t . I’ve seen kids do projects by themselves that a whole team would be lucky to pull off 20 years ago.

@@mathewmolk2089 It was not the wokies. After WWII, the government made the GI Bill and a college education was within the reach of every person who served. From then on, everyone promoted a college education. Not that it was wrong. Solid statistics showed that a person with a college education earned significantly more than one who did not have one. It is true.And, most parents wanted their kids to go to college. Additionally, many people came here with only a suitcase or the clothes on their back. They worked hard, then sent their kids to college. Some of these kids have become famous, rich, or both. Others have become important writers, composers, musicians, actors, directors, doctors, businessmen, and politicians. Without a college education, and usually more than one degree, you are at a disadvantage in this country. You earned a good living as a machinist, but I bet the guy who was your supervisor and had a degree in mechanical engineering earned a lot more. Never criticize those who have a college education. You only make yourself look dumb. By the way, today it is even nececessary for the local cop to have a degree in criminal justice from the local community college.

A hass 6 axis would have this done in minutes

@@UNcommonSenseAUS I wonder how much it would cost for that Hass machine plus operator for those few minutes, versus these guys for presumably a whole day. I bet its close, but maybe there's a question about availability of such machines wherever this is (Pakistan, at a guess).

@@fartingfury about £40-60 a hour but you have setup time aswell to account for, it will certainly take a good few hours for a modern machine shop to machine this component especially since they have no drawings to work back from.

Mating worm if it’s a multi start it will have a large jump and fixed center distance it will bind up.Bronze is the material that must be used aluminum will wear out in a instant.

Yes because that break easy it's not harden

It wouldn't work as a patern because it's not oversized to allow for shrinkage, on top of that the shape of the gear teeth would be impossible to remove from the sand.. my guess is it's just a temporary part to keep a factory running until propper material can be sourced

That is what i was thinking when i watched this for a while lol makes sense to me for sure

That gear would be as useful as a chocolate tea pot

@@deeferdownunder Aluminum - I was thinking the same thing.

@@deeferdownunder Aluminum can be hard anodized, and with proper lubrication and light service it might last longer than you would think. No where near bronze, but maybe they could not get the bronze material for an extended time.

What kind of equipment do you think builds new equipment. That said the machines you saw in this video is still used daily in machine shops in every country on this planet and still available for purchase new. My point is a very large portion of machine work done in the world today especially 1 off work is done with manual equipment

@@gullreefclub The gear in the video wasn't the crap we see being made today.... no computers... and other technology. Just solid old school machines that last.

A manual lathe is not primitive. It's old but it's not even antique.

Hello Kevin; Everything here seems like I am arguing about this vid, but what is thought of as "primitive technology" as you put it is what was used in WW ONE to make parts for machines back then. Those machines still work perfectly if taken care of. The FACT the the guy had to jam a screwdriver into the over arm on that horizontal mill shows they can't even be bothered to make something as simple as a gib. Something I was taught to do with a file back in the 70s when I was still in high school. There is no mystery or craftsmanship here. This is a video of how to do things all wrong and in a slip shod way. He knows what someone long ago showed him, but if he had a new horizontal milling machine, I imagine he would wonder where to jam the screwdriver in to take up the slack in the gibs. (Start by adjusting the gibs in the firs place, IOW..)

@@dcw56 primitive technology was the wrong terminology that I used. Basically saying these guys sit on the floor hold parts with their toes and still manage to get the job done. I don't think that crankshaft is going to last forever but they make do with what they've got. I think that's my real point. And it does look pretty primitive but they do get the job done even if it's only a temporary fix.

Wtf the cluelessnes in this comment is amazing

If you think this is primitive technology then maybe look up what sort of machines Rolls Royce uses in their factories.. Rolls Royce is still using the same machines they used back in the 50s and before

Yes I thought the wedge "screwdriver" was a humorous touch. 😄👍

@donalfinn Thank you! Being a German Geologist, I've spend decades in ""under developed"" countries. Our western arrogance towards those people never ceases to amaze me! Countless times we needed spare parts, to be ship in and worth thousands of dollars. And then, bingo....a local mechanical , or electrical workshop produced a replica, even better than the original. For a handful of dollars....and a pad on the shoulder....how patronizing and unfair? Just because people are poor, and so are their countries....does not mean they are dumb and stupid!!! I have seen cars and trucks rebuilt....very, very few western workshops would be capable of doing that. As for the screwdriver....that is the essence....improvising.....and it works! Cheers

You could also add some nikasil coating on the aluminium as we do it for aluminium motorcycle cylinder blocks, but i don't know if they have access to that technology

@@kukipett An interesting idea, we have hard anodising which prevents wear for a little while but it wears through creating an abrasive paste when the remains of the anodised layer mixes with the lubricant and greatly increases wear. My suggestion is always to use the right material for the job along with the correct heat treatment before and after machining, finish grinding and then lapping and polishing as required. I don't know if the pattern gear in this video is brass or bronze but I will say that brass is a useless material to make a gear of this type where there is a sliding action between the gears, with a rolling action and low torque brass may not be too bad but the correct grade of hard bronze is the vastly better material

That's what I was thinking also, I wasn't sure if it was Alu what they were using as a replacement because it seemed like a massive downgrade from the original. BUT it's probably what they have to work with because they also used a cutting tool with a broken tooth. So it might be like sitting on a remote island, having to build a two story house with only a kitchen knife😉

Working around that type of equipment it's best not to use gloves or wear loose fitting clothes. Which both applies to these artists. I worked in a boilermaker shop for years and saw the result of a fellow getting a glove caught while use a large drill press.

You, sir, seem to understand. What that guy did is not magic. It is not hard to do. It is not even high school shop class quality on any kind of manual machine.

The man knows how to do what he was taught, but it is still hack work, and the video description makes it out to be some kind of miracle. It is common work in most other countries.

A Lathe and Horizontal mill are NOT primitive tools. In a tool and die type shop a customer can bring in a one off job and a tool maker will be in the office typing the invoice before you can be done writing the program and loading the tool changer. CNC is not the answer to everything. In fact there are jobs (like welding up a gear with a couple missing teeth in a bevel gear and machinating them) that are totally impossible on a CNC machine. The Lathe and Bridgport can still get the job done. The only place the cost of a CNC machine can be justified is when you are turning out multiple parts. On onsie-Twosies CNC will never pay for itself,,,,and most of the time is actually slower then manual machines when they are in the hands of a skilled machine hand. ,,,,,, Hell 90 percent of CNC operators cannot even re-grind a drill bit.

The original gear-wheel is made from bronze to be able to withstand loads and wear & tear. It is usually driven by a hardened steel 'worm-gear'. I am familiar with these types of bronze gears. They are designed for lots of abuse. The aluminum replication will not hold up very long under load.

Man, the chatter marks in the gear gullets are off more than a thou. Didja see that gear cutter bouncing up and down?

Your right, but as a qualified technician in mechanical engineering I will say that both aluminium and brass are both highly unsuitable materials to make this gear from, the material should be either C90700 (SAE65) bronze or S45C carbon steel which will need to be heat treated, checked for dimensions, possible finish ground then lapped to the correct surface finish/texture on the gear teeth before use. With all these videos that demonstrate 'amazing skills' it's not enough just to be able to manufacture the item, the product also needs to be made of the right material in the right machinable condition in the first instance, then heat treated and ground as required then polished and/or lapped before it will be suitable for reliable use. This is why OE gears and parts in general are expensive and why these well meaning and skilled artisans working in sheds with dirt floors are cheap.

@@rotax636nut5 As a machinist at the trade for decades, I do not think these guys are either "clever" nor (at all) artisans. I do not mean to demean them. They are doing what they have been taught, and seemingly have not progressed for three to four generations. Still doing the same ol' thing to make something work for a little while longer. That is NOT what a real machinist does. We make parts that are at least as good as the original spec, and yes, sometimes that means sending it out for heat treating. Skipping steps because of ignorance or price does not make one an artisan, (I am not an artisan. I'm a machinist, manual machines only) nor does it make you a machinist, or even clever. I understand that these guys may be just working to make enough to eat, but that does not make them an artisan any more than a guy who grows corn or a man who catches fish for market. Using clapped out machines and getting things "good enough" by eyeball does not a machinist make. Fixing the old machine would be a good first step in becoming a machinist. I do understand he needs to eat, though, but that lathe in the shop is only about 10 years old... The money for it came from somewhere. It is not an old machine. The old Adcock, Now that is an old machine. Fix it!
