Just FYI, I watched this gentleman use this lathe a number of times about 6 months ago. At the time the lathe appeared to be brand new, but about half of the toolpost bolts were already in the current shape. It seems that since then he has bent and mushroomed all of them. I suspect it is a Chinese lathe, and the metal used for the bolts was the equivalent of rubber. I see other Pakistanis cranking on the bolts on their toolposts the same way, but they haven't destroyed the bolts in the process. He could easily replace those bolts with scrap fine-thread screws that he finds lying around on the ground from disassembled broken parts. I watched a video not long ago by an Indonesian lathe operator that took some old wheel studs and turned them down into new toolpost bolts for his lathe. This guy could do the same. Six months ago he was welding the same way in the chuck; all Pakistani truck repair people do this. Since then he has learned to put a board over the ways to not screw them up too badly. This is the first time I've seen him use a rod to the toolpost for ground. I think he did that because he wasn't getting consistent conduction thru what is left of the headstock bearings. One of his techniques has improved though. I didn't see him open the top of the lathe and reach into the drive belt compartment with the motor running. Six months ago any time he needed to change speeds he would turn on the motor, release the belt tensioner, and then reach into the belt compartment to move the belt from one pully to another. He also seems to now be buttoning his shirt cuffs. When he was adjusting the belt with the motor running he had them flapping loose.
Interesting piece of work for this repair. My only real question is how well will this hold together, sometimes welding is not the best answer. Interesting video. 👍😁🇺🇸
I have been using a lathe for over 40 yrs and I have never seen tool post bolts in that state. It seems that they use an extension bar to tighten everything down. It would appear that if they don't hit something with a hammer then they use an extension bar to tighten. Number 1 tool in Pakistan is a hammer, No. 2 tool is a bigger hammer, No. 3 is an even bigger hammer. No 4 is an `extension bar, No 5 is a bigger extension bar.......................An the tool is more than likely blunt.
I was a machinist for 25 yrs, in some very terrible shops stuffed with a lot of older equipment, the bolts will just start doing that with repeated use, and if they are hard to replace, they just get worse, its not necessarily because of the cheater pipe, (remember these dudes are like 90lbs soaking wet and like 5'2" a little extra leverage is probably needed) As for hammers, seen plenty of "machinists" use hard faced hammers to "adjust" everything from Kurt vices to CNC spindle alignment... if its the tool you have, then use the tool you have (difference is the US "machinists" had the right tools at hand, just too fecking stupid to use them... hence why I'm happier cutting trees down now)
OMG 🤓 Never seen tool abuse taken to this level. Pretty nice lathe, where someone has been completely borking the tool holder. Have those bolts been tightened to the point of turning elephant feet ? I'm sure the truck driver will enjoy every single mile of drive on that forever vibrating drive shaft.
That lathe looks pretty new. And like a pretty nice machine. But it won't be for long. Those screws on that tool post, all mushroomed and bent. And grounding the welder through the bearings. I wonder how long before the bearings start getting crunchy feeling. And how long will they run the lathe with bad bearings. I have watched many of these types of videos out of Pakistan and India and have been amazed by what they make with so little. And amazed at the lack of even rudimentary safety precautions. Like pouring cast iron with bare feet. But these guys really take the cake. Their new and expensive lathe will be junk quite soon. That's too bad.
no not grounding through bearings. they put a rod or pipe between tool post and the pipe when welding. then later use the dead center to center and push the parts . no rolling elements in the dead center
They take care of their stuff. Imagine one of them asked you to use your truck? That's a no. There is many videos of them repairing something critical. Definition of insanity doing same thing and expecting different results. We understand it, they don't.

It looks like at least part of the they’re grounding the welder through rolling elements, a definite no-no. Also, we didn’t see the shaft dynamically balanced. It’s going to beat the u-joints out of it.
Never seen machinists so unskilled before zero knowledge, I’d be surprised if the prop shaft lasts a week. Welding work was a crap as the machining work.
@from the dark side of the moon was told they supposedly have “1095” steel rod. Of course, the person who spoke of the matter might have been an unwitting liar - as in he may have been “sold.” If it was anywhere close to 1095, then forge and machine the blanks to size, then harden them. 1095 can be oil quenched readily - it’s similar to W1. (I’ve done it)
After all that work making a sleeve they just end up butt welding it with no v Groove ? The whole thing was pointless? The only thing holding that tube together is a surface weld ?
Of all the videos I have seen of Pakistani people working wonders with almost nothing, this is the first where I have seen inept cowboys butchering both the work & their equipment. They, in my opinion, are not going to be trading for long.
Driveshaft tubing is usually ERW mild steel, sized for the job, and to resist whirling failures. These guys appear to know little about metalurgy and materials, which isn't any surprise. This is common throughout these regions, the basic thing seems to be, if it looks like steel, its OK. Repairs like this would not be carried like in this anywhere here in Australia, the whole tube would have been replaced, its actually illegal to have a weld anywhere on a driveshaft other than at the ends. Welding above the lathe bed, and making the earth circuit through the head bearings, is going to ruin your lathe as well. Speaking of lathes, Ive never seen a lathe that size belt driven, they must be locally made.
@@atlasflame2510 Yes I know that, no doubt its failed due to extreme overload that these people regularly do. It appears they purchase second hand worn out trucks from japan and China, fit an extra axle or two, then fit huge springs (which only serve to support the 200% overload) then drive them on awful roads, QED, failure. Thankfully it appears they rarely go over 30km/h. The original design of the truck was fine for the service it was intended for, but 200% overload will kill anything.

Отдельно лайк за заточку резца.
THEY WELD WITH 7018 RODS. THE ONLY THING THAT BOTHERS ME. IS IF YOU DON'T CLEAN YOUR WORK ,REALLY CLEAN. ANY FLUX LEFT INSIDE. NOW THAT WILL WEAKIN THE WELD. WIRE WHEEL BRUSH , WIRE BRUSH. HAS TO BE CLEANED VERY GOOD, OR IT WILL FAIL.
my question is who funded all this equipment and "training"? that equipment looks pretty new in a pretty old part of the city/town. nothing is for free sooo.....
I never thought I would be suggesting a country needed more lawyers, but certainly they do there. Liability does not seem to be even a remote concept there. The next bus load of nuns that goes over a cliff has no recourse in law there.
On big rigs we'd replace this driveshaft versus repair.. Big rig drive shafts take on a lot of stress especially when approaching 80k pounds or more.. If this was a small car I'd definitely agree with repair
Да не очень. Вроде и правильно, но швы не разделаны, особенно когда крестовину приваривал. хотя фаску делал на станке, мог бы и там точнуть, но шов красивый, снаружи и не понять. Может конечно от души проварил, на то и надежда. Смотрю этих парней - красавцы конечно! Из кизяка и палок всё, конкретно в этом видосе на заточку резцов и расплёсканные болты разцедержки больно смотреть - трубой же затягивает, но делают же работу! Респект!
if that lasts half a year ill be shocked. an axel has as few parts as possible, to reduce possible failure points, these kids just added 3 failure points
Mmm, sketchy stuff.. They don't make a root for welding = hoping for the best. Considering the fact they always overload the trucks, it will be back soon in the shop if it doesn't roll down some cliff.. So, next is the misuse of bolts and tool holder = to cry for.. There is absolutely no need to use that excessive force to bend and mushroom the screws.. Also I'm amazed no one of them gets the sleeves caught in the chuck.. The toolpost also should have a stop-rotate pin that prevents it of free spinning on the central screw... Ya, very sketchy stuff, the worst is when they always use some extensions over extensions... Then the lathe ground when welding.. =( all the lathe will be soon covered in weld splatter... Let's not talk about safety in flip flops.. I can't stand those on in the shop where welding, forging and similar stuff is going on. Does anyone know why they throw anything they disassemble in the sandy dusty soil first?
They actually think that will work??? That is going to break, twist off as soon as any torque is put on it. There is just so much wrong with that drive shaft. I have seen bush fixes better than that. It’s not like they don’t have tools to fix this, it’s the welds and how they attempted to fix it. How old is that kid trying to fix it? 12-13 years old. I bet that drive shaft is older than he is, LOL.

Отдельно лайк за заточку резца.
👍👍👍!!!
👎👎👎👎👎👎👎!!!!!!
THEY WELD WITH 7018 RODS. THE ONLY THING THAT BOTHERS ME. IS IF YOU DON'T CLEAN YOUR WORK ,REALLY CLEAN. ANY FLUX LEFT INSIDE. NOW THAT WILL WEAKIN THE WELD. WIRE WHEEL BRUSH , WIRE BRUSH. HAS TO BE CLEANED VERY GOOD, OR IT WILL FAIL.
my question is who funded all this equipment and "training"? that equipment looks pretty new in a pretty old part of the city/town. nothing is for free sooo.....
They bought from their legal money.
I never thought I would be suggesting a country needed more lawyers, but certainly they do there. Liability does not seem to be even a remote concept there. The next bus load of nuns that goes over a cliff has no recourse in law there.
If I only had an emoji of a bus load of nuns going off a cliff! 🤣😂
I give that poor shaft about 20 feet before it snaps again… but praise to allllaahhhh
Good
Thanks
Muy bueno👏👏👏👏
Tornear um peça cortante e manusear sem as luva sem os óculos tudo errado.
I think the guy down the street made the tool holder bolts in his back yard using scrap...
On big rigs we'd replace this driveshaft versus repair.. Big rig drive shafts take on a lot of stress especially when approaching 80k pounds or more.. If this was a small car I'd definitely agree with repair
Its truck drive shaft
@@wonderingskills1 I know, reread my post... I can already tell you don't understand what I was saying
Лайк. Молодцы!
ماشاء الله مهارات عالية
Jazak Allah
Очень хорошо! 👍🙂
Да не очень. Вроде и правильно, но швы не разделаны, особенно когда крестовину приваривал. хотя фаску делал на станке, мог бы и там точнуть, но шов красивый, снаружи и не понять. Может конечно от души проварил, на то и надежда. Смотрю этих парней - красавцы конечно! Из кизяка и палок всё, конкретно в этом видосе на заточку резцов и расплёсканные болты разцедержки больно смотреть - трубой же затягивает, но делают же работу! Респект!
@@ЕвгенийАверин-з5з вот есть токарный станок, ну освежи болты в резцедержку или сделай новые. Но нет, что-то им мешает
@@МаксимКороль-э3е Они специально расклёпаны, чтобы не потерять 😁
Ох, уж эти ребята))
Ммм как же балансировка? Грузики на кардане знаете ли не просто так
el ayudante se cubre de las chispas con la mano desnuda XD
У одного "мастера" не получилось, "другого" позвали.
Thank goodness we have duck tape.
My legs are hurting just thinking of spending that much time crouched like that.
if that lasts half a year ill be shocked. an axel has as few parts as possible, to reduce possible failure points, these kids just added 3 failure points
Как можно было угандошить так резцедержатель!???
اللہ آپ کی مدد
Глаза-аааа😵
tay nghề rất cao
Бедность это не порок !
Is it just me or does it look like this guy has no idea how to do a quality job
Mmm, sketchy stuff.. They don't make a root for welding = hoping for the best. Considering the fact they always overload the trucks, it will be back soon in the shop if it doesn't roll down some cliff.. So, next is the misuse of bolts and tool holder = to cry for.. There is absolutely no need to use that excessive force to bend and mushroom the screws.. Also I'm amazed no one of them gets the sleeves caught in the chuck.. The toolpost also should have a stop-rotate pin that prevents it of free spinning on the central screw... Ya, very sketchy stuff, the worst is when they always use some extensions over extensions... Then the lathe ground when welding.. =( all the lathe will be soon covered in weld splatter... Let's not talk about safety in flip flops.. I can't stand those on in the shop where welding, forging and similar stuff is going on. Does anyone know why they throw anything they disassemble in the sandy dusty soil first?
👏Good repair
Thanks
Horrible
Destroying the tool post and the set screws by MASSIVE overtightening. STOP THAT.
Ma grand mère soude mieux que ça !!!
Excelent
💔
Molana good welder

They actually think that will work??? That is going to break, twist off as soon as any torque is put on it. There is just so much wrong with that drive shaft. I have seen bush fixes better than that. It’s not like they don’t have tools to fix this, it’s the welds and how they attempted to fix it. How old is that kid trying to fix it? 12-13 years old. I bet that drive shaft is older than he is, LOL.
Да-молодцы мужики.в таких условиях исполняют "чудеса".в нашей банановой державе, родине слонов и прочего-просрали все.и остается только смотреть и завидовать как они там работают на таких древних станках.у нас нормальные современные станки спецом в чермет гонят только что бы людям не достались.
Это вы про украину?
@@user-folk1987 а что в Украине тоже как и расии все просрали и попилили?
Это не "чудеса", а криворукое лепилово, с попутным убиванием станка.
@@1971Fin Ты меньше смотри укро тв, а лучше приедь в Россию. Ты удивишься, но там не так как показывают у вас по тв ))
@@Leonid_01 да ну хули мне в нее ехать?я живу в росии 50 лет и вижу все своими глазами.и да-укротв у нас не показывает к вашему сведению а только триколор где все прекрасно.только не в телевизоре совсем другая картинка.
Вот резцедержатель ушатан вхлам
Yo manejo un camion en USA, y no creo que esa reparacion a 65 o 70 millas x hora no produzca vibraciones, ,Yo no me arriesgaria,,,los respeto mucho,,,pero creo que en USA ,,MUY POCOS SE ATREVERIAN A HACER ESO
Not good. the splice has less crossectional area then the tub itself.
