Using a digital spirit level is an interesting idea. I think a 1:8 reduction gearbox, which larger lathes are usually equipped with, could be conveniently used here. This gear is usually designed so that the gear has a number of teeth divisible by 3 and 4, just so it can be used as a simple dividing device. You simply switch the lever from the intermediate position to the 1:8 position and roughly rotate the chuck by hand. With 1:8 gearing, the motor won't usually turn that easily, and for this purpose it might be enough.
Never ground a welder through a bearing. Asking for trouble. If you must weld on a lathe (not recommended) clamp the ground next to the weld - not through a bearing.
The title doesn't describe the project. It appears to be a chuck back plate. If that's a bearing that I saw you install on the press I'm guessing this chuck is going on the tail-stock? Wakodahatchee Chris

Can you educate me, why is that? It is a conventional lathe, I believe that the electrical motor will not suffer. There is almost zero electrical parts on this particular lathe. Ohh, never mind, saw a comment about arcing in the bearings. Makes sense.
You're degree of accuracy and mine are worlds apart. Also where are your safeguards when welding. Absolutely no one I know would even consider grounding through the head stock of a lathe !!
I wish I had seen this before I tried making the back plate for my 1942 South Bend 10R! So much math... I didn't have another chuck to hold it in (hence the need for a back plate), but I could have used the digital angle gauge... wow, easy! Too late, I'm done, but I'll remember that for next time!
Halo bang, saya baru kelas 11 smk, jurusan mesin Saya salut dengan cara kerja abang, sangat baguss Numpang tanya bang, mini digital level kegunaannya apa ya?
considering it has a chuck and a bearing in it, probably a rotary weld positioner or something. Either that or "high precision chuck backplates" that are on amazon or ebay
Niw spawa się w uchwycie tokarki a jak już to robisz to zakryj uchwyt od oprysku stopionego metalu. Jak widzę to pracujesz jakby to była cudza maszyna i robota.
Jaws, not teeth! Centring a workpiece in a four jaw is a 90 second operation after the first one of a batch, and... a four jaw holds tighter than a three jaw... I've roughed 1.5" off a diameter of a steel billet using a HSS knife and face tool, at low speed, requiring high torque, which I doubt the machine's three jaw could have transmitted... 7.5HP machine... Anyway, centring in a four jaw... The chuck face has reference grooves in it. They're cleverly arranged so you can compare the independent jaws "corners" to the grooves, interpolate the position of the jaws between grooves. So, you adjust the jaws 1,3, and 2,4 so the workpiece centres roughly, but reasonably well, by eye, then...Either use a DTI to check the workpiece centres on axes 1,3, and 2,4, or... spin the chuck reasonably slowly, and, holding a piece of chalk (blackboard or French) in your hand, approach the workpiece with the chalk, until it touches the periphery of the workpiece. It'll leave a witness mark in one spot if the workpiece is running out a great distance, and you do it right... (with bright stock, you have no excuse for being far out...) Anyway, if the mark's at jaw one, relax the tightening screw at jaw three, add pressure at jaw 1, retighten jaw one, repeat the chalk thing. if you're lucky, the chalk mark will be at both jaw 1 and 3, or if not, there'll be a wider mark on jaw 1 side... Then deal with 2, 4 Continue until approaching the billet with chalk, the periphery is marked continuously... If you're turning cast stock, it may not be round, nor will "black bar" then, it's down to experience and judgement... Once you've centred your first component, when you unload it, loosen jaws 1 and 2, remove finished component, mount next, tighten 1 and 2, you'll not be far out, check, adjust, turn. 90 seconds for a component you can mount by hand. Big stuff, handled by hoist or crane... A but longer... I was taught not to hold black bar in a three jaw chuck, and never did... But... Not everyone was taught that... In my last job, I ground my three jaw's chuck jaws in situ far more often than I had previously in my entire working life... "Use the four jaw for turning black bar, you arse!" didn't have the desired effect with fitters... You can regrind four jaw independent chuck jaws more easily than those from a three jaw self centring chuck... (or a four or six jaw self centring chuck) I used to leave a four jaw mounted on my "best" lathe at the end of the day, to deter fitters from using it overnight. They thought they could turn... Most, if not all, were wrong...
Using stick welding while mounted on a machine tool (Lathe) is horrible. Weld splatter everywhere! Using gas shielded MIG or TIG generally produces no weld splatter. While there was an effort to protect the lathe bed from permanent damage, the lathe chuck definitively got lots of abuse here.
This looks like a fibus pin for a fanooten valve. Judging by the strict precision exhibited here this is most likely something for the aerospace industry.
Pamiętaj aby nie puszczać wiórów wstęgowych bo może ci poobcinać palce, rękę lub nawet i kark. Dobry tokarz wie jak pracować aby nie tworzyły mu sie splątane wstążki na nożu bo czasem pęknie Ci nóż.
Да геморой это а не метод , не точный не позволяет сделать муфту без люфта . Отверстия для фланца или такого рода соединения . Если нужно точно ставьте энкодер на 3600 имп на оборот .
Nun, es ging schnell den Winkel zu finden. Hat aber nichts mit Drehtechnik zu tun, allenfalls Messtechnik. Mit einem Zirkel hätte man das ähnlich schnell finden können.

love the heath and safety, welding with bare feet exposed priceless, but nice work.
Albo żartujesz albo nie znasz się na pracy w tej branży. Przecież odpryski poparzą Ci stopy. Oszalałerś?
Hi Yanto. Best regards from a german saturday afternoon.
🙋♂️🇩🇪
Hy to brother Frank.. in Indonesia Saturday afternoon to 😁♥️
Vamos arriba hermano Messin excelente, un Abrazo para ti y todos los hermanos Indoneses ❤❤
Bravo !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
How often do you replace spindle bearings on the lathe? Arcing in the bearings will destroy them. Good luck. You are going to need it.
Łożyska wrzeciona wymienia się tylko podczas remontu. Chyba, że tokarz źle pracuje na tokarce.
We probably don't have the same notion of precision work on a lathe
Teknik yg sulit untuk ditiru 🤍👍
Stupenda idea!!!👍 a me spesso occorre montare un mandrino uguale al tuo...Bravo!!!

Arc welding a part on a lathe, may be a technique that you would not do tomorrow in the same shop.

Where would you place the ground clamp?
Dobrze mówisz. Pozdrawiam.
Saya suka teknik nya🤩👍
Tez coś. Co to za technika? Niedouczonego ucznia.
Очень красивая работа, когда все получается!
Смотрю тебя, и сам хочу быть токарем. Очень интересная работа
Купи станок и точи на здоровье.
@@fainderskurs-koi8767 уже едет станок
В трехкулачковом патроне было-бы удобнее.
Тебя не смутило, что сварочный ток проходил через подшипники патрона и убил их?
Bueeens profe mesing, sigue apoyándonos con tus grandes lecciones, desde Perú 😊😊
Haha dobra odpowiedź. ,,Nauczycielu bałaganie".
좋은 영상 감사합니다. 응원합니다!😊😊😊😊😊
awsome work,sir.very nice
I'm sure you're lathe is not happy about all the welding spatter in/around the chuck and on the ways.
Can an anti-spatter spray be used?
@@laszloiszlai yes, please do.

Brilliant Hard working 👍👌
Yanto, thanks for another enjoyable video but I'm curios. What was the purpose of slotting those 3 back plate holes?

Я чувствую, что в токарном мастерсте Я БОГ.
В 4 -х кулачковом патроне так точить может только не получив нормального образования по токарному делу.
This is going to make me wonder what your making for a week. 🤣

@@gorak9000 next vid shows it's a combination chuck and live center.
A very good example to see exactly how NOT to do mechanical work. Unbelievable stupidity in all aspects.
excelente trabajo
Gracias brother ❣️❣️😘
Cool work thanks 👍
good job 👍👍
Hi guy very good work very dish TV multimeter how much guy please reply thank you😊
What is the incisor in the video? что за резец на видео ?
2:40 Honestly, after watching welding on the lathe, I gave up watching the rest of the video.
Types of turning blades?
Лайк. Молодцы. Отлично!👍👍👍
Сынок тебе станок не жалко .после сварки в станке ты выбросил все подшипники в переднеи бабке .очень скоро .
Es lo ke le dije yo pero no entiende ke se dañan los rodamientos o baleros
А еще этот умелец не умеет затачивать резцы, стружка должна закручиваться, а она лентой сползает.
Amazing ❤

Жёсткий тип,сварка в шлепанцах,да он посуровее челябинских мужиков будет)

Szép munka mester
А как вам удаётся так быстро центровать деталь на четырёх кулачковом патроне?
Да так, стук бряк и готово!
практика. чем больше тем быстрее
Bom dia! Muito bom.

how do you centre things with four independendt teeth ?

so with the four tooth ones, you do not have the swirly synchronisation plate on the back? you just individually adjust?@@robertlawson8572
It makes it much easier if you use coolant

Excelente, Son unos magos con los metales
Used to do that sort of thing in a 3 jaw chuck lot less faffing about.
Too much runout, you have a lathe and you don't have a dial indicator.
In drei oder vier Jahren hat er die beste Drehbank der Welt .🥰
Hey mr big game 😆.
I did more than 20 years ago! It's not new.
Everything was ok until you butchered the part with that angle grinder.
There's far easier ways of doing this.
