Henry Ford eliminated expensive brass radiators and fittings from his early model T cars, so that later versions of the same model T were about half the cost to the consumer, thus triggering the Automobile Revolution. He sold 15 Million model T's as a result, which was a staggering achievement in the 1920's Nowadays the Chinese are using cheap materials and techniques to make their products so affordable, that the consumer has a terrible dilemma: _"Do I buy a reliable German machine or a cheap Chinese knock-off🤔🤔🤔"_
@@BrassLock please be careful with your suggestions! I'm from Austria, so I know pretty well what it means to buy a good car with qualitative parts build in. Today we are at a point, where not every German car has to be better than a car from somewhere else. Yeah, Chinese cars are complicated.. On one hand, they aren't seen very often here in Europe, because the search for replacements is ridiculously hard and yes, there are that many better cars, but the most Chinese ones.. But on the other hand there aren't many German cars anymore, which are build from nothing but German parts, not even cars that are mostly build from parts made somewhere in Europe.. I think more than 80% of the German cars are mostly build of Chinese crafted parts, what tells us a few things: 1. The Chinese definitely made some of the worst, but also some of the best materials and parts for different products. 2. The fact, that many cars are still put together in Germany or at least Europe, may be a big point in all of this. The controle mechanisms are very thought through and each and every part will be handled and put together with much more care, than it's the case with many other car factories in other countries and they will be combined with parts made in Europe or Germany. To spend more money will set the chances very high, that you will get a very solid German car, but don't let yourself fool by old and glorified names, because many things have changed.

I used to have an old Atlas lathe (before it became Sears Craftsman) that had a back gear pin gear like that one. It also had a series of holes on the flat face of that gear toward the chuck that you could use the headstock as a divider. There was a retractable pin that went in that fixed the position that was accessed outside of the drive housing. Your use of the lathe as a manual shaper is pretty cool. You also did good by putting in those screws in the cast iron before brazing. There is a nickel type welding rod you can use in place of brazing for cast iron. For gears, brazing is so much better. This is a nice post of this sort of metalworking trick. Thank you for posting.
I used to have a Halifax 524 lathe (read Atlas if in US), it is sadly missed, but I chose to keep my children (then aged 9 & 11) & so I lost the lathe.
Very good job. The tapped brass screws provided a good foundation. I've had good luck brazing cast. I like this process better than the preheating and the nie rod.
@@johngilbert6810 I think the brass would be more maluable and less likely to break like brittle cast steel. I could for any method of repairing broken cast, simply because of the process of welding cast. It's a lot of work for it to fail in the end because of a little bit of cool air causing it to crack.
That bull gear looks like it's about done, it looked like it had several other teeth repaired already. One positive thing with the way you did that and having it mesh with the harder gear the softer metal will work its teeth in overtime using the squish Factor. I never thought about using my lathe as a shaper. Thanks, I learned something new. From Virginia USA
You need to have the exact same shape on every teeth, there was too much load on them because the ones that were repaired before got the wrong shape. So now another 3 gonna be broken and again right next to the teeths that was just repaired... and how exatly different metal in something that needs to have every teeth identical is a beneficial factor?!
@Biały if you are wondering I was referring to imperfect duplication of the teeth using brass would allow them to wear into the steel teeth on the other gear. That is what I was referring to.
@@jkucukov well this repair vedio should give you hope on fixing it,, you can mig are Arch weld it also,, l did a smaller gear with one missing tooth with mig and you con concentrate the weld more and not have to use screws just cut groove with cut off wheel for weld and then use a file to shape it.
@Fire Metal, I’m very impressed! Your whole approach to this problem was creative, great use of brazing, and turning your lathe into essentially a shaper with a rotary table is the cleverest thing I’ve seen in a long time. Best of luck on your UA-cam channel. 👍🏼😁
30 Years before I met the same problem in my lathe gear.I have done the same work .but I am using ms welding rod and file it the gear teeth.Still no problem in this gear.
We did this at TAFE (technical college) during my apprenticeship and it's called "pegging". I had to do it in an emergency situation at work once to keep production going. We also made a whole spur gear from scratch at TAFE - turned the blank on the lathe then cut the teeth on the milling machine using the indexing head.
Are you saying the gear teeth would be formed completely out of stud shafts, no brazing needed to make the tooth shape? I can't picture that, especially with the small amount of material those studs could be seated in. I think the brazing is just as much to reinforce that thin "rim" and the bolt shafts, as it is to provide material for the tooth profile. If the gear was the same thickness from shaft to outside flange, there would be enough meat to support the studs, but I don't see that thin flange surviving the torque on a back gear. Cast iron is too brittle for the small amount of material in that flange to hold up.
I have a Smith and Mills 17" shaper that is probably 100 years old. It has several broken teeth in the crossfeed drive gear that have been repaired, who knows how many years ago, by exactly the method you describe. The studs interlock slightly, they haven't been welded or brazed. It appears that the studs were filed to shape. The gear is pretty fine, the teeth are less than an 1/8" thick. The machine works just fine. I don't subject it to heavy use, but it was worked plenty hard in the past. I have also seen the same repair on several similar sized gear teeth on a 13" Southbend lathe. It probably started out as an emergency repair, but worked well enough that they never bothered to replace the gear. We are so used to the landfill economy and throwing everything away and buying new that people are horrified at thought of the terrible things that might possibly happen as a result of some guy in a third world country making do with what he has and repairing an expensive or hard to find part. I swear, if our knuckleheaded banksters and politicians manage to blow the world up one of these days, it will be the barefoot mechanics of the third world that pick up the pieces and put it back together.
@@haroldmedalen6757 You have no idea how right you are. I have a milling machine of the German company Biernatzki, this year it turned more than 80 years old. And this is quite a working and accurate machine, which I completely disassembled and repaired with my own hands. And this company no longer exists. Such a rarity from the past.
@somebody else Both the gear on my shaper and the one on the lathe are done with the row of studs alone. The studs very nearly overlap and it looks like they were hand filed to the proper profile. The work is very finely done. It is possible that they were both done by the same person, as both machines have been in our somewhat isolated town for many years. I haven't found anyone who knows anything about the history of the repairs. I expect they were done back in the days when we had one steamship a week, not daily air service like today. If a part was damaged or failed and you needed the machine, you would have had to figure out how to fix it and keep it going however you were able. I think this guy's repair brazing over the studs, then cutting the teeth to shape with the tool in the lathe is probably a more durable repair by far than the studs alone, but I know I could run my shaper all day without any problems from the repaired gear. (Knock on wood!)
In my trade we had bronze rod high strength nickel alloy that I use to braze tungsten teeth to 1 metre cutting wheels . These rods are recommended by the manufacturer to repair or replace missing teeth on gears and also for high strength brazing .
It's a very common way to repair cast iron. When is done right it's almost as strong as the original material and the braze is rarely what fails. Keith Rucker does a lot of these repairs on UA-cam and explains a lot of it in detail if you want to look it up
That is just brilliant! Using the saddle of a lathe as a shaper!!!! (It just goes to prove the old adage: necessity is the mother of invention). Good job! 🤗
Absolutely brilliant as a "field repair" which was driven by necessity. Faced with the circumstances of what he had before which was "totally fuck8d-up" he now has something which, with a bit of tweeking with a set of Swiss files and engineer's "marking blue", enables him to use the machine. Is the lathe going to be as good as new, obviously not, but with careful usage he can now do things with it that in it's previous state was impossible. Necessity is always the mother of invention.

Yep, that’s the way the Master Machinist I apprenticed under taught me. Turn the carriage of the lathe onto a shaper with a boring bar and a form tool. Waaay quicker than having a new gear made.
@@lost4468yt I'm not sure what you are trying to say the original comment was just describing the process in the video more or less saying the master machinist he was an apprentice for taught him the same method to save money instead of having to have a whole new gear made
Needing a machine up and running faster than the days to weeks it will take to get a new part in isn't that high pressure. On a decades old machine it might be the only option.
For the shaping of the teeth, it will be very worth your time to deal with the slop in the toolpost, topslide, and however you had the gear fastened to the chuck. The part moved several times, the boring bar was pushed away from the gear way more than it should have been, and the topslide rocking on the carriage made me watch several times because I couldn't believe it was moving that much. The way you're going about that repair is perfectly fine, and a nice job on the brazing. But, you'll get much better results if you can fix the rigidity of the setup.

These guys are masters of repair. In the West this part would have been replaced most likely with a new one. Labor costs in the West make such a repair unaffordable. This is assuming they can find workers who are skilled in this kind of work.
I performed a repair on a back gear decades ago, I cut grooves such as for a keyway and brazed in steel metal bar the correct dimensions and then filed the profile in, the lathe is probably still in use with the Turkish navy now.

The answer is in the video and it is very visible, next to the broken teath you have teaths that also have bronze in them and on top of that the shape of this teeths are different=the load on teeths is not distributed properly...
Brass is softer than cast iron so in time it will be worn out and starts missing teeth and eventually it will break , but for temporary fix it will do .
@@Lucas_sGarage ER 70 is too brittle and will ruin the very old gear which is probabley cast in some wrought iron. That will break. Better to use a good aluminim bronze bronze or a nickel bronze brazing over the screws. Another possibility (that depends on the material of the gear) is to weld with a machinable stainless steel like the 312, generally that welds very well in most steels and irons and it's very strong. The SS 312 is often used to repair gear boxes and crankshafts.
@@Lucas_sGarage Hard to find aluminium bronze, expensive cupro nickel 20 %, and easy to get SS312 are suitable : not too tough, easy machining, good ductility but hard enough. The real problem It's to get a good anchor of the brazing or welding between a very old gear of unknown alloy, with maybe impurities and probably a lot of carbon with the added metal of the new teeth. It's a tough problem. I've had excellent results with the 312 which gets a good fusion even with hard to weld steel alloys and a lot of irons without heating to much, is pretty ductile so very resilient to vibrations and alternate stresses, and a good surface hardness. It has made to fix blades on turbine engines with hot combustion gases heating it. So on a old gear it's peanuts for the 312.
The gear or the repair? The teeths gonna last because the shape of the new teeths is wrong so the new teeths will be underloaded, the teeths right next to it gonna breake because they gonna be overloaded just like it broke before as you can see previously repaired teeths right next to it.

Great. One interesting thing however is why if a bronze repair is so all fire good why gears are not made of all cast bronze. Does anyone know?
@@evanpenny348 Because the price of lathes would far exceed the wallet of the consumer. Henry Ford eliminated expensive brass radiators and fittings from his early model T cars, so that later versions of the same model T were about half the cost to the consumer, thus triggering the Automobile Revolution. He sold 15 Million model T's as a result, which was a staggering achievement in the 1920's
Nowadays the Chinese are using cheap materials and techniques to make their products so affordable, that the consumer has a terrible dilemma: _"Do I buy a reliable German machine or a cheap Chinese knock-off🤔🤔🤔"_
@@BrassLock Good point
@@BrassLock please be careful with your suggestions!
I'm from Austria, so I know pretty well what it means to buy a good car with qualitative parts build in.
Today we are at a point, where not every German car has to be better than a car from somewhere else.
Yeah, Chinese cars are complicated..
On one hand, they aren't seen very often here in Europe, because the search for replacements is ridiculously hard and yes, there are that many better cars, but the most Chinese ones..
But on the other hand there aren't many German cars anymore, which are build from nothing but German parts, not even cars that are mostly build from parts made somewhere in Europe.. I think more than 80% of the German cars are mostly build of Chinese crafted parts, what tells us a few things:
1. The Chinese definitely made some of the worst, but also some of the best materials and parts for different products.
2. The fact, that many cars are still put together in Germany or at least Europe, may be a big point in all of this. The controle mechanisms are very thought through and each and every part will be handled and put together with much more care, than it's the case with many other car factories in other countries and they will be combined with parts made in Europe or Germany.
To spend more money will set the chances very high, that you will get a very solid German car, but don't let yourself fool by old and glorified names, because many things have changed. Today the German automobilindusrtie isn't the same as 20 ago so please.. always research! Don't buy just because it's German!

Honestly, watching this kind of video puts me in my place. How much I have to learn. Thanks for sharing!
The whole process and techniques are excellent, I learned something new today. Cheers
Very good repair ! - You used your lathe as a shaper ! - Great idea - Well done man 👍👍👍
I've done it for keyways on gears and pulleys; works amazingly well, if a bit tedious.
@@UncleKennysPlace but rewarding in the end once you've got your key way done ! :o)
Very cool process, the happy music at the end was a loud surprise lol
Thanks for sharing ...This is something I will try out
I used to have an old Atlas lathe (before it became Sears Craftsman) that had a back gear pin gear like that one. It also had a series of holes on the flat face of that gear toward the chuck that you could use the headstock as a divider. There was a retractable pin that went in that fixed the position that was accessed outside of the drive housing. Your use of the lathe as a manual shaper is pretty cool. You also did good by putting in those screws in the cast iron before brazing. There is a nickel type welding rod you can use in place of brazing for cast iron. For gears, brazing is so much better.
This is a nice post of this sort of metalworking trick. Thank you for posting.
I used to have a Halifax 524 lathe (read Atlas if in US), it is sadly missed, but I chose to keep my children (then aged 9 & 11) & so I lost the lathe.
@@pinohaxk628 Who asked you to reply so rudely?
this is the best "thinking outside the box!" example i have seen in a long time!
Very good job. The tapped brass screws provided a good foundation. I've had good luck brazing cast. I like this process better than the preheating and the nie rod.
The screws were steel, adds more strength too.
If the steel teeth broke the brass teeth will break even sooner. Nothing to be learned here unless you have dirt floors and no shoes
@@johngilbert6810 I think the brass would be more maluable and less likely to break like brittle cast steel. I could for any method of repairing broken cast, simply because of the process of welding cast. It's a lot of work for it to fail in the end because of a little bit of cool air causing it to crack.
Nice work!👌🏻
The braze would be quite soft compared to the rest of the gear, but if it work, fantastic! 👍
That bull gear looks like it's about done, it looked like it had several other teeth repaired already. One positive thing with the way you did that and having it mesh with the harder gear the softer metal will work its teeth in overtime using the squish Factor. I never thought about using my lathe as a shaper. Thanks, I learned something new. From Virginia USA
You need to have the exact same shape on every teeth, there was too much load on them because the ones that were repaired before got the wrong shape. So now another 3 gonna be broken and again right next to the teeths that was just repaired... and how exatly different metal in something that needs to have every teeth identical is a beneficial factor?!
@Biały if you are wondering I was referring to imperfect duplication of the teeth using brass would allow them to wear into the steel teeth on the other gear. That is what I was referring to.
That's impressive,, l buy and restore vintage lathes,, I'll never be worried about broken gear teeth again thanks for the lesson.
I got a 1911 Von Wyck lathe with a broken gear like this.
@@jkucukov well this repair vedio should give you hope on fixing it,, you can mig are Arch weld it also,, l did a smaller gear with one missing tooth with mig and you con concentrate the weld more and not have to use screws just cut groove with cut off wheel for weld and then use a file to shape it.
Finalmente alguém que sabe fazer o reparo da forma correta.
@Fire Metal, I’m very impressed! Your whole approach to this problem was creative, great use of brazing, and turning your lathe into essentially a shaper with a rotary table is the cleverest thing I’ve seen in a long time. Best of luck on your UA-cam channel. 👍🏼😁
Thank You | Marc McKenzie
That's exactly what *I* was thinking too. This was brilliant in every way.
30 Years before I met the same problem in my lathe gear.I have done the same work .but I am using ms welding rod and file it the gear teeth.Still no problem in this gear.
My boss did that to the back gear on his small Sheldon lathe many years ago. They are still using it. It's probably lasted 30 years or more.
ভাই আপনাকে অনেক ধন্যবাদ সুন্দর একটি কাজের মডিপাই দেখলাম।
We did this at TAFE (technical college) during my apprenticeship and it's called "pegging".
I had to do it in an emergency situation at work once to keep production going.
We also made a whole spur gear from scratch at TAFE - turned the blank on the lathe then cut the teeth on the milling machine using the indexing head.
Congratulations for that job,I remmenber when I was the techinical school,I wached the instructor, maked a job liked this.Greeting from Uruguay 🇺🇾🇺🇾
I remember learning this technique as an apprentice, it works better with thicker studs which slightly interlock , you dont need to braze then
Are you saying the gear teeth would be formed completely out of stud shafts, no brazing needed to make the tooth shape? I can't picture that, especially with the small amount of material those studs could be seated in. I think the brazing is just as much to reinforce that thin "rim" and the bolt shafts, as it is to provide material for the tooth profile.
If the gear was the same thickness from shaft to outside flange, there would be enough meat to support the studs, but I don't see that thin flange surviving the torque on a back gear. Cast iron is too brittle for the small amount of material in that flange to hold up.
I have a Smith and Mills 17" shaper that is probably 100 years old. It has several broken teeth in the crossfeed drive gear that have been repaired, who knows how many years ago, by exactly the method you describe. The studs interlock slightly, they haven't been welded or brazed. It appears that the studs were filed to shape. The gear is pretty fine, the teeth are less than an 1/8" thick. The machine works just fine. I don't subject it to heavy use, but it was worked plenty hard in the past.
I have also seen the same repair on several similar sized gear teeth on a 13" Southbend lathe. It probably started out as an emergency repair, but worked well enough that they never bothered to replace the gear.
We are so used to the landfill economy and throwing everything away and buying new that people are horrified at thought of the terrible things that might possibly happen as a result of some guy in a third world country making do with what he has and repairing an expensive or hard to find part. I swear, if our knuckleheaded banksters and politicians manage to blow the world up one of these days, it will be the barefoot mechanics of the third world that pick up the pieces and put it back together.
@@haroldmedalen6757 You have no idea how right you are. I have a milling machine of the German company Biernatzki, this year it turned more than 80 years old. And this is quite a working and accurate machine, which I completely disassembled and repaired with my own hands. And this company no longer exists. Such a rarity from the past.
@somebody else Both the gear on my shaper and the one on the lathe are done with the row of studs alone. The studs very nearly overlap and it looks like they were hand filed to the proper profile. The work is very finely done. It is possible that they were both done by the same person, as both machines have been in our somewhat isolated town for many years. I haven't found anyone who knows anything about the history of the repairs. I expect they were done back in the days when we had one steamship a week, not daily air service like today. If a part was damaged or failed and you needed the machine, you would have had to figure out how to fix it and keep it going however you were able. I think this guy's repair brazing over the studs, then cutting the teeth to shape with the tool in the lathe is probably a more durable repair by far than the studs alone, but I know I could run my shaper all day without any problems from the repaired gear. (Knock on wood!)
In my trade we had bronze rod high strength nickel alloy that I use to braze tungsten teeth to 1 metre cutting wheels . These rods are recommended by the manufacturer to repair or replace missing teeth on gears and also for high strength brazing .
Smart man, nailed that repair!
how does the soft braze last compared to the original cast iron? i. sure it’s very low torque and rpm.. or else that would fail fast
It's a very common way to repair cast iron. When is done right it's almost as strong as the original material and the braze is rarely what fails. Keith Rucker does a lot of these repairs on UA-cam and explains a lot of it in detail if you want to look it up
That is just brilliant! Using the saddle of a lathe as a shaper!!!! (It just goes to prove the old adage: necessity is the mother of invention). Good job! 🤗
Absolutely brilliant as a "field repair" which was driven by necessity. Faced with the circumstances of what he had before which was "totally fuck8d-up" he now has something which, with a bit of tweeking with a set of Swiss files and engineer's "marking blue", enables him to use the machine. Is the lathe going to be as good as new, obviously not, but with careful usage he can now do things with it that in it's previous state was impossible. Necessity is always the mother of invention. Greetings from the UK !.
Not a bad temporary fix. I'll last long enough for you to replace the whole gear. Nicely done.
This is economically advantageous in countries where the work of a locksmith costs $ 10 for a 12-hour working day, and CNC machines have not even been seen in pictures.

Для тех,кто не понял зачем это всё,должен помнить,что обломанные зубья шестерни из литья (чугуна),гараздо слабее чем болты из сырца и наплавленной бронзы....
Да ты гонишь, так это времянка, пока новую не сделали 😂
In a throw away world, absolutely beautiful to watch
Интересный способ, как я понял - шестерня из чугуна и поэтому не наплавлял элекстродами, глядя на "износ" зубьев можно сказать что это не нагруженная(об этом говорит и то из чего она сделана) шестерня а сломались из за чп какого-нить. Бронза/латунь канешь не настолько прочна и поэтому вставлены болты для усиления, зато она лучше скользит в отличии от сыромятины металлической. Думаю шанс что она походит есть, способу быть.
Временное решение для того чтобы оборудование не простаивало пока придет нормальная деталь.

Yep, that’s the way the Master Machinist I apprenticed under taught me. Turn the carriage of the lathe onto a shaper with a boring bar and a form tool. Waaay quicker than having a new gear made.
Did you know that not every place on the planet is under the same economic pressures as conditions as you?
@@lost4468yt I'm not sure what you are trying to say the original comment was just describing the process in the video more or less saying the master machinist he was an apprentice for taught him the same method to save money instead of having to have a whole new gear made
Needing a machine up and running faster than the days to weeks it will take to get a new part in isn't that high pressure. On a decades old machine it might be the only option.
@@6181green I thought they were being sarcastic.
Gracias amigazo saludos desde Colombia.
For the shaping of the teeth, it will be very worth your time to deal with the slop in the toolpost, topslide, and however you had the gear fastened to the chuck. The part moved several times, the boring bar was pushed away from the gear way more than it should have been, and the topslide rocking on the carriage made me watch several times because I couldn't believe it was moving that much.
The way you're going about that repair is perfectly fine, and a nice job on the brazing. But, you'll get much better results if you can fix the rigidity of the setup.

this begs the question: why did the gear break in the first place? If the cast iron gear broke, then how long will braze last?
The answer is in the video and it is very visible, next to the broken teath you have teaths that also have bronze in them and on top of that the shape of this teeths are different=the load on teeths is not distributed properly...
maybe it was allready repaired
with brass solder
you just have to put on a new layer after every couple of turns ;)
very creative and genius, very useful, my friend..
Muito bom.
Excelente serviço.
Awesome , very smart repair , 💪👏
weld it up with cast rods steel and cast don,t mix that well !And if you brase it you should heat the whole piece up and keep it heated .
Its a lathe part, so a slow speed and low torque application. I think it will hold well.
There are the bolts that hold the teeth very well. Its an excellent fix ,these teeth are now stonger than the others.
Brate svaka ti čast!!! Odgledao sam sve od početka do kraja! Ja bi otišao na otpad da nadjem drugi deo
Brass is softer than cast iron so in time it will be worn out and starts missing teeth and eventually it will break , but for temporary fix it will do .
bronze*
probably you could weld it like with er70 or so
@@Lucas_sGarage ER 70 is too brittle and will ruin the very old gear which is probabley cast in some wrought iron. That will break. Better to use a good aluminim bronze bronze or a nickel bronze brazing over the screws. Another possibility (that depends on the material of the gear) is to weld with a machinable stainless steel like the 312, generally that welds very well in most steels and irons and it's very strong. The SS 312 is often used to repair gear boxes and crankshafts.
@@pabloricardodetarragon2649 is about finding a sweet spot between hardness and toughness
@@Lucas_sGarage Hard to find aluminium bronze, expensive cupro nickel 20 %, and easy to get SS312 are suitable : not too tough, easy machining, good ductility but hard enough.
The real problem It's to get a good anchor of the brazing or welding between a very old gear of unknown alloy, with maybe impurities and probably a lot of carbon with the added metal of the new teeth. It's a tough problem.
I've had excellent results with the 312 which gets a good fusion even with hard to weld steel alloys and a lot of irons without heating to much, is pretty ductile so very resilient to vibrations and alternate stresses, and a good surface hardness.
It has made to fix blades on turbine engines with hot combustion gases heating it. So on a old gear it's peanuts for the 312.
These guys can live on planet mars, with little resource left. Still able to survive.
Pretty impressive, how long it lasts remains to be seen.
The gear or the repair? The teeths gonna last because the shape of the new teeths is wrong so the new teeths will be underloaded, the teeths right next to it gonna breake because they gonna be overloaded just like it broke before as you can see previously repaired teeths right next to it.
Next time something breaks on my car, I'm going to India to get it fixed. Fantastic workmanship and will probably work out cheaper.
Necessity is the Mother of Invention.
This is really great. Some times you just can't get a replacement gear.
