I wonder: 1. How many lathes, tool bits and drills they go through? 2. How much time is spent sharpening them? 3. How can you not protect the lathes ways from the weld splatter as you weld directly above them? 4. How do you clean off that splatter after it ends up sticking to them? 5. Why don't you use a coolant spray when cutting, drilling and threading? 6. Why should I even be asking these questions?
I always used coolant except for a few materials where air or some other method would be used, that was using high speed steel of course. Nowadays with carbide tools being so common they don’t seem to use coolants although I would have expected it to help the finish if nothing else.
The nearest he would get to my lathe would be to drag out the swarf. Shocking machine work and method. Towing a decent load over a few pot holes and making a couple of sharp turns and you're back to square one!
No good machinist would weld on his lathe without at least covering the ways. These guys really abuse the machine. BTY the lathe in the beginning of this video is red and at the end it is gray. ??? Hmmm
Not My idea of a professional, looks more like a beginner hack than anything. The initial pin had a crack all the way through, this fix removes half the strength of the pin and replaces it with nothing more than threads. Once the weld cracks due to the flex of the weakened steel, (Threads will flex where the weld wont) those threads wont hold anything. This fix is a failure waiting to happen.
@@Ultimateprocess7Ребята, здравствуйте! Я согласен с предыдущим автором. Эта деталь будет работать сначала. А долго она отработает? Эта тяга или палец, от серьёзной, тяжёлой техники. И нагрузки там не маленькие. Очень интересно, как эта деталь будет работать? Мужики, с уважением из России, токарь, фрезеровщик.
If whatever torque was able to break that off to start with, I just don't see how this repair is going to last very long. Obviously the repair will always be weaker than the original solid part that broke... JMHO!
would like to hear from commentors how they would repair this (purchasing a new one is not an option). I am not an engineer and am curious to the responses.
The initial break occurred where there is a stress concentration where the pin joins the eyelet. This repair does nothing to address that as the lathe tool made a sharp joint again, with no radius between the broken sections. Basic metallurgy. Threads are NOT a 100% fit and they will flex once the stress cracks the weld. Might work for a while under light loads, but not under the loads this pin is apparently put under. Witness the original break!
@markseibert6369 I totally agree about the stress concentrating at the 90 degree corner and needing a curve there to spread the stress. (Called a fillet - had to look that up.) I once watched a woman stop a crack in my windshield by drilling a hole at the tip of the crack. I think the threads are irrelevant, because he appeared to weld deep enough to join all three pieces, the crack will go through the welded area or beside it IMHO. This is probably staged anyway.
Finally, a simple repair that will hold even if done wrong. He pretends to take a critical measurement. The nut will take up any slack if off a little either way.
These men use a stronger technique to reassemble steel pieces. They strengthen the connection with bars of steel threaded into each part, then weld them together. To me, it is brilliant.
@@stephenmeeks684 This part broke under load. He repaired is and now it is much much weaker. This was probably a forging that snapped. It has nowhere near the strength of a solid unit What is Your credentials to say this will work? ( and will be safe)

this answer will apply to all questions You are asking
They dont care.
If they would read the comments, they could improve. The will not improve

Appreciate you sharing your thoughts and expertise. We're always open to feedback!

Как я понял, им документацию от этой детали не дают. Поэтому делают как могут. Ну поработает немного.... 😊
It would be alright if they put some JB Weld on it.

This video should be titled. " How not to make this repair."
whats all the welding for the holes ok it was just snapped rewld
Good work ❤
You wouldn't know good work if it poked you in the eye. This is appalling workmanship.
Nooooooooo!
Passing welding current through lathe bearings is huge NO NO
Thar explains the finish. Never pass welding current through head-stock bearings.
That’s very good advice. Thank you.
Glad you found it helpful.
When the threaded insert was placed it is only 1 1/2 turns not much holding it in
sharp toolsmake less noise

A lo Picapiedra y ordinarios sin protección
Super jest to zrobione i bardzo jest to super fachowo zrobione pozdrawiam serdecznie.👍👍👍👍👍👍👍👍
🤣🤣🤣🤡
A master machinist
Parabéns pelo o trabalho de vcs.
Obrigado! 😊
Dear God do not not let this man ever work on safety critical equipment. He's a hack.
I hope it work for a week😁
this connection method is very good but this person's work is sloppy and careless.
What, no JB weld in their country?
The piece he used to join them was too large, this made the welded portion much smaller and thereby weaker. It may look good but I wouldn’t use it.
they dont care

6013?
the thread is too loose
El mejor trabajo que es visto mi felicitaciones sonmejores que los polacos ❤😅❤
Wasting time. Making a new pin will be quicker and stronger.
No, no, you misunderstood, this is a mess that is happening strongly.
No, no, you misunderstood, this is a mess that is happening strongly.
Correct. There can be metal fatigue and possible hairline cracks. A new pin is the only way to go because they take a beating.
Yay such may kamiyab hotay hai ya vidio Tak ?😮😮😮😮😮😮😮😮
This work is successful.
It is now walkable.❤
Don't clean surfaces before weld it's not good for welding

Penso sia difficile fare un lavoro più merdoso di questo.
It's just "stupid" to weld on an unprotected lathe! These videos only serve one purpose, Humor!
Horrible finish on the lathe. Like it was cut with a cold chisel. Hack job.
❤❤❤❤❤🎉🎉🎉
Professional Mechanic??? this is a work for beginners. no need any special work, just welding
serviço muito mal feito. O eixo rosqueado ficou solto e uma casquinha de soda por cima.
Na pecionata...
It still not a perfect circle
never push a stick weld
Very poor welding
Ha erőhatásnak van kitéve csak egy anyagból gyártható le....
Maaaaa... veramente qualcuo paga per un lavoro pessimo come questo? 😂😂😂

@ I apologize for making this judgement as I thought it was a different repair I made the comment about. I was wrong, sorry.
notthe best at cutting thread
What a massive hackjob with those INCORRECTLY GROUND cutting tools! So bad i gave up watching the stupid video.
