I literally jumped in my seat when I saw "British Standard Whitworth" on that drawing. In fact, I went back and looked a second time to make sure it wasn't a nightmare. My Jaguar mechanic's hat fell of the shelf. Beautiful machining, nonetheless, Chris. Thanks very much. Have a peaceful Sunday. Liebe Grüße aus Deutschland.
Крис, очень сильно впечатляет Ваше умение измерять резб! У других Ю-тюберов, русских, критерием для качества является то, что "гайка накручивается!". Успеха!
@@frezistta Да, я соглашаю с том. Но не мене, в обычной жизни (и большенстве токарных дел) "если гайка накручается, она накручается - и всё". Тоже, я смотрю некоторые русские токарные каналы (Слава Петров, Дневник Токаря, и другие) и там очень часто они проверают винт накрученем гайки. Гайка и винт "работают" вместе, и оны должны "согласатся" друг с другом, и это самое важне. Дюймы и милиметры - тоже, и если нет гайки это одиный способ проверить винт - но прямо всего гайка и винт должны соответствовать. Тоже, извини мой плохий русски, поздравляю из Польши.

How do you cut tight tolerances on different diameters? When you dial in you finish tool to a certain diameter, it may not be accurate when machining in another place, considering how far away they are in this machine. Do You make test cuts before every diameter or the machine is so accurate, that you offset once and cut it all?
Cześć czy możecie mi wytłumaczyć sposób mierzenia tego gwintu za pomocą tych pałeczek? Mam np. do nagwintowania gwint zewnętrzny na rurze 4" ma ona średnicę , wymyślam 100mm, nacinam gwint G11 np. i w czym mi te pałeczki pomogą, przecież one nie dotrą do końca gwintu?
Do you trust the chuck clamping force to counteract the tailstock pressure or is there some material backing up the shaft on the chuck end? And how do you determine the right tailstock force? Thanks.
@@ChrisMaj Thanks, that clears it up. I realized you have what is known as an 'oil country lathe' - big bore and back chuck. I already mentioned in another video that I am puzzled about using a 4-jaw in conjunction with a center, as the system is over constrained. Why not use a dog? As I understand it, you use the 4-jaw as a dog by setting it to a zero dial indicator reading or, on rough material, by adjusting it to the dimensions noted when spinning it between centers, correct? It looks like you would have to be very careful to not put huge pressure on the center and the workpiece by being even slightly off. Well in fact putting pressure on the center is inevitable because there is no play in the system so essentially you are turning every jaw against a hard stop so to say, I guess you will have to take it slow with minimal adjustment steps. An interesting case was the shaft you did between centers with a center in the back chuck and the front chuck clocked in to the rough material, again I could make the case for using a dog BUT the front chuck works like a steady rest so the overhang is reduced. I found that a very creative use of the machine.
I’m not sure if anyone has asked this on previous videos, but how do you deal with these long components bending and moving after removing the live center? When holding .001 or .002 total tolerance on something that large, is it not influenced by tailstock pressure and the part sagging during turning? Do you deal with any cylindricity requirements?
Hi Chris, I regularly get asked for items like these for a steel mill I do work for. Could I send you the drawings to have a look at as and when please?
How incredibly anal, disiplined, and focused on attention to detail does one have to be to not screw this up? I get nervous just watching this thing cut thinking about all of the ways I could screw this up. Great job mate!
1:00 You've said that they made a revision of the drawing. So you are telling me that there are companies out there, which are still drawing by hand? I didn't expect that. I thought the drawing is ~25 years old and you are doing a retrofit.
Panie Krzysztofie czy na tej maszynie można wpisywać programy w kodzie ISO? lub wygenerowane na komputerze z jakiegoś CAMa? Czy tylko cykle stworzone w Manual Guide? Pytam z ciekawości bo bardzo podoba mi się ta maszyna :)
Gotta love all the bs engineers would put on drawings lol, like no tool marks on a radius😂 which most likely is clearance not touching anything, I run into stuff like that all the time making semiconductor parts, they also will call out + or - .002 thou on counter sink diameter or depth when they are buying hardware that isn’t machined from McMaster carr LOL.

Very uncommon thread! 55 degree thread if I’m mistaken, actually never made that thread myself.
I did the same, I went back and looked another time 😂

_"гайка накручивается"_ - well, if it fits, it fits, right? ;-) Пиндосы всё делает по другому ;-)

good video Chris Maj..thanks for your time
Beautiful job, Chris
Hey Chris,
Approximately how many hours from start to finish for the lathe portion? Beautiful work as always.
Cheers,
Tom
Thanks Chris. Beautiful as always.
Все на рисунке такое красочное, что слепит глаза . Everything in the drawing is so colorful, it dazzles your eyes.
Lovely piece of turning 👌 thanks for sharing👍
Absolutely beautiful work as always mate, Cheers
Nice Work !

Hi, Chris. Great mashining as always. It would be great if you add some cutting speed and feed!
Good job!
Selalu jadi yg terbaik

0:22 There's a center in the chuck. Tailstock force by feel
@@ChrisMaj I caught that but I thought it looked too small for the large bore in the part. Thanks.
@bigbattenberg 0:35 for something like this, I always make plugs for both ends.

I wonder how they get the hole in a piece that large and long. I assume it came with the hole already.
From the drawings I presume that it is a shaft for a turbine kind machine. Am I guessing right?
BTW, greetings from Poland.
It's for the steel mill industry. Pozdrawiam.
@@ChrisMaj I didn't know that such an application might also require internal lubrication. Thanks!
Beautiful piece of work. To bad it gets covered up in a piece of equipment.

Nice job Chris, was it roughed out and ''allowed to move/ settle'' before the finishing ops?
А резьбовой резец, какая марка?

can you maybe do a video one time on how you program parts?
I think, and he programs manually without software
@@speedhuntersrb that still involves programming doesn't it? i mean more like go through step by step start to finish
that and I count that it goes step by step@@ikbendusan
mashine model?
Way cool.
👌👌👌👏👏🤩
