Repaired the damaged thread of the lathe machine's Four 4 Jaw Chuck which is difficult

[@un-factory]

The ability to repair lathe chucks is really great. We support your long-standing know-how.

قمة في الحرفية و الإبداع. ارفع لكم القبعة. تحياتي الاخوية من المملكة المغربية. ❤❤❤

[@jarikjakov5108]

Кулачки сделаны из инструментальной лигированной стали и еще закалены. Что вы там навариваете, оно отвалится или обломится.

[@srinivasansanthanam749]

Really good job done. regular oiling will give more life for this chick parts.

[@lawrencedennerle5303]

You fellows sure do a good job taking care of the shop machinery..🎉

[@horstmuller7512]

Good job! Now all tolerances are guaranteed less than 2 fingers.

[@wazzazone]

Well what do you expect will happen when you use a six foot tube to tighten the bloody thing.

[@adinis3202]

Perfecto 💯, buen trabajo en cuba también lo hacemos 👌

[@bernardbush4199]

I want to know what they were chucking on in the first place to tear the acme threads out of the chuck jaws . They must have had a 10 ft. cheater pipe and four guys hanging on it...

[@davidhamm5626]

At the very least....

[@delcat8168]

Yeah, but you can break whatever you like as long as you can mend it.

[@first_namelast_name4923]

They clamped something very large to the chuck, so the jaw was only engaged on the last thread and they broke that one thread of. So now they had a jaw with 1 thread groove damaged. Rinse and repeat, every time breaking off one thread groove, or perhaps only a part of grove. After repeating 15 times you have to damage like in this video. No need to break all the length at a single time.

[@bernardbush4199]

Thats very true but after the first few pieces where broken off inside the chuck you would think they would notice that the jaws were a little hard to adjust. That damage is quite extensive.

[@mckutzy]

I forever see them using a damn bar on the chuck key... It really doesn't need it on this size of lathe... Turing a +12" propeller shaft... well.... that's different entirely..

[@franciscoassis2862]

Parabéns pelo trabalho desses caras

[@giovannifinievoli8825]

excellent work!

[@tottietortelini777]

Great Work 👍

[@CNCMaster00]

Thanks

[@shadrin499]

Очень хорошая идея. Молодцы. Спасибо.

[@АндрейНикитенко-ф4с]

Your ingenuity is admirable. I have my doubts about the accuracy and durability, but I hope this lathe chuck will be usable for at least some types of work.

[@jamesdrake2378]

I get your point but with a four jaw it is not as critical than with a scroll chuck. The four jaw is adjusted by each jaw. Durability is as you wrote another issue.

[@bernardbush4199]

And then there's the matter of the metallurgy. All that welding on the jaw has got to change the hardness. They don't show any heat treating afterwards so the next time they chuck on something that large I wouldn't want to be anywhere near that lathe...

В реальной жизни, токаря очень часто переваривают, ростачивают, фрезеруют кулачки (например под определенную операцию)

[@stephenaquilina6628]

I've worked for 25 years as a machinist,how did you manage to break a chucks thread?and these parts are not to be repaired they have to be changed.😮

[@vikassm]

Don't even go there 😂😂 Probably re-repaired, worn out jaws. Happens all the time when repairing cast iron parts with 6013 rods 🤣🤣 Which is a total disaster in itself, but who cares about safety in that part of the world!!

[@davidlbrown309]

Yep just the right comment

[@milliondollarbaby1911]

😂😂😂 that's just for video purpose dude ... That time and effort will never match with the cost of that jaw part..we all know that 😅

[@RobertLBarnard]

​​@@vikassm No one would make chuck jaws out of cast iron, right? I worked in a pattern shop, most of the time we'd duplicate (wood or CAD patterns) into iron (once we did Ford engine block cope & drags in stainless 🥵). But every once in a while a mistake or ECO required a patch and change. If it was small we could heli-ark and recut. But that little bit of tungsten in the weld.... Most of the time we'd pocket the area, drop in & pin a new piece of iron, then recut. Cutting iron is just like cutting butter.

[@vikassm]

​RobertLBarnard The ones in this video are cast iron for sure. Probably from a local foundry which makes cast iron replica machinery from melted engine blocks and the like. Usually also containing tons of impurities which make the cast iron come apart in layers when stressed. It's a miracle any of this works at all 😮 I'm not making this up, Seen more than one setup just like this up close. Nearly convinced myself to work in one a few decades ago, now extremely happy that I didn't 😂

[@Eduard8139]

Они умеют оживлять все что давно мертво! Только как это все в дальнейшем живет?

[@RobertLBarnard]

I wonder what killed it originally? The threads look to have been broken off; as through the chuck was over tightened (as opposed to wearing off from use). Perhaps they need a larger lathe?😅

[@lewjones7272]

Downright crafty!!!!

[@djalmabatista5286]

Muito bom 👍 parabéns 🎉🥳 Trabalho show de bola 👍 vocês são top 10 👋👍

[@amjadmohmood6391]

Probably got some dirt or metal shavings in the threads and kept cranking despite the increased resistance

[@HappySingh-bx2jh]

Great ingenuity to save a $2000 chuck from the scrap bin.

En lo personal.es muchisimo mejor Hacer la Garra nueva ya Hecho 2 Garras y 3 Tornillos.mil veces mejor.pero Buen Trabajo

[@piperdoug428]

man i had my doubts but they got it "good enough"

[@davidangus7559]

Brilliant!!!!

[@therealspixycat]

The claw should be aligned with the grove and not to the hand grounded plane before cutting the thread?

[@peterhalstead7281]

You blokes that are finding fault just remember where they are and what they have to work with before you get on your high horse

[@hamadmengal6716]

I think anyone roughly used the 4jaw chuck

[@MsBrugos]

The worst thing of this mess up is that the chuck is a Chinese K72 SanOu, readily available even as spares.

[@rajanraja8366]

Didn't even preheat the part first😂

Although safety doesn't seem to be a concern since they wear no safety equipment what-so-ever anyway. No safety glasses, sandals, loose baggy clothing around moving equipment, poor house keeping, etc.

[@MrMidiman33]

Safetygear are Sandalettes and Kaftan

[@bernardbush4199]

Guess they don't have an OSHA organization either.. worker's comp? What's that.?

[@MrJitendra007]

Woah..for every special material welding rod is the material...😂😂😂😂..So material science is not required at all..😂😂This is what happens when you are not educated or you havent tried to educate yourself...

Other than the obviously FUBAR threads the chuck looks ok.

😂😂otra mentira!!! Que animales ,por lo menos me divierten . Quizá alguien piensa que las reparaciones son verdaderas😂😂😂😂😂😂😂.desde su poca preparación y su ignorancia sobre mecanizado se las ingenian para hacer creer que es verdad . Son un desastre !!!!!
