I know you metric guys have a hard time with inches, so I thought that might help. If you ever have a bigger one in your store, let me know, I'll be the first one to get it 😉
As a young design engineer in the rubber and plastic industry I designed rubber mills for Francis Shaw & Joseph Robinson. This was everyday stuff back then 800hp gear sets, huge bronze water cooled bearings on the journals 90” wide 24” dia rolls some micro finished other’s helical grooved. Loved every minute before I went or king for Loctite. Then of course we in the U.K. began our great decline and deindustrialisation, now there’s no trace of these once colossal companies and all that skill base is almost all dead and buried. Makes me so sad that so few today have work they can take pride in, beats the work in a call centre by some margin and what’s the point of burger flipping by comparison. Nothing like the smell of cutting oil.
Don’t mock the inch, fractions are absolutes, base 12 is a pretty good mathematical system, ask a mathematician. More difficult no doubt than base 10. Engineering wise the very first standards were set by Joseph Whitworth in 1841 and he measured to one millionth of “a banana” and designed the most efficient threads in terms of clamp to applied torque, to that date. His measuring device could show the expansion of a metal bar by the heat from a finger, 140 plus years before everyday accuracy of “a thou”. True engineering genius. Remember too that with base 12 and fractions there’s no rounding errors commonplace in metric, the blight of pcb layouts.
The combination of "oh sh*t thats expensive" and "oh sh*t if i break it it gonna take 3 months to get spare material and we never hear from the customers again" also maybe "oh sh*t if i drop that thing we gonna need a new machine or workshop floor/crane" is quite gnarly yes. Only had 2,75 tons on the machine so far but that thing was stainless so price wise some muscles were clenching indeed :| Excellent job as usual there man!
Hello,my name is Guilherme I really like your videos, I'm Brazilian, I work with cnc and you are an inspiration to me, keep teaching and encouraging us thank you very much. Sorry for my English but I don't know how to speak it. I used a translator to try to get this message across.
Yeah, I've been watching Kurtis probably from the beginning, so I thought I'll use their banana ruler in my video. They gave me a few pointers with all that TH-cam stuff, but I just don't have the time to spend on all the editing.
I'm curios the reason why you finished the center section diameter after the milling work? And on a different machine. Was there something special about that center section that I missed? Was it because the Hankook didn't have enough X travel to reach that section? Love your work. You are certainly making the most out of the Fanuc control. No CAM required! All the best, Tom
@@ChrisMaj Bummer. You had to use the old clunker to finish that nice arbor shaft. That old girl looks like she was rode hard and put away wet. Blue chips and chatter for days. Cheers, Tom
Had to laugh at the beginning Chris. If the crane went haywire and dropped that piece of material it would splintered those 4 x 4's like they were toothpicks. I know , I know , CYA right?
Wow that’s a big lump of steel, Chris am I reading the colour of the steel correctly?? Has it been case hardened? Or is that just the colour of the steel as it came to you? Also a shout out to Kurtis of CEE for sending you a banana ruler love it 😊😊 As always Chris just wonderful work that you do, I never got to play at stuff that big.
I think the forging company did some sort of heat treatment after roughing. Yeah, I bought one for CEE store just for fun. They did send me a few other things.
@@ChrisMaj That is exactly why I don't post videos. I helped my disabled nephew with his cameras and mounts, even built him an editing computer. A professional videographer donated a $5k camera. That's when I learned about left only audio, which opened the audio rabbit hole... So I don't post my work because I have plenty of irons in the fire to keep me busy.
Hi Chris happy Sunday. Thank you for this new video of machining a huge axis of five tons probably intended for the navy or heavy industry? I saw that you put the banana ruler of Kurtis the Australian from the EEC on your piece, it's funny because I follow his videos like yours on You Tube, it's no coincidence. See you soon to see your great videos Chris thank you.
Hey Chris. Have you noticed all of your recent videos have the audio shifted to the left side only? You might be using an editor template so this gets repeated. It has been this way for a couple of months now. Thanks!
How do you go about running such heavy parts? Seems kind of terrifying, what would you set your pressure and is there any tips you can give to roughing heavy materials? Currently at my shop we have a guy that will retire at the end of the year and he roughs huge heavy shafts. I want to learn how to deal with such big parts but they seem intimidating any tips?
The chuck and the tailstock are all manual, so kind of go by feel. Keep your jaws tight, or the piece might spin on you when taking big cuts. Don't drop it on your lathe.
1:57 does that mean, that the center can hold 5 tons or that the part can weigh up to 5 tons when its a straight cylinder? what if one side weighs 4.9 tons and the other 100kg and the 4.9 tonms are on the center side?
Looking at this "11,000/ 5 tonnes" piece, somehow this Russian word for a "finished piece" (or "workpiece") came to my mind - which is "detail", деталь. : )

Really nice work. Could you please let me know how you prevent chuck jaw marks on the final piece because we struggle alot with marks upto. 5 mm deep when we tighten heavy pieces on CNC lathe. Your earliest response is highly appreciated.
0:38 as you can see, I have a center in my chuck, and most of the weight is resting on it. On the finish surface, I'll use brass or aluminum shims to prevent any jaw marks.
Loved the video. Quick question, though. Do you have a 4-way tool post mounted to the existing toolpost without any support? Am I just not seeing that right?
Czemu zasłaniasz niektóre średnice na rysunkach? Jakiś własny patent firmy? Chciałbym zobaczyć jak coś takiego się montuje. Jeśli na czop wału coś jest osadzone ze wciskiem to jak to zrobić?
Bo chciałem tylko pokazać te które w tym czasie obrabiałem. Może uda mi się coś nagrać z montowania reszty rzeczy. Na ten wał nachodzi jeszcze większe koło, będzie nagrzane i później nałożone.
They keep changing the picture of what is mounted in the lathe? One minute it is a machined portion in the chuck and the next instant it is a not machined portion in the chuck. What are they trying to pull?

Good to see you are using accurate measurements there mate, but I think you need a bigger one 🤣👍🍌
Hey... it's that guy! LOL.

Tom: Well, that is what communists do to countries.
Kurtis is going to love that ruler usage
I have to place an order for a bigger one 😉
Im so glad you guys are able to upload that stuff. Really nice to see such huge parts being made!
Good job and keep it up!
I'm trying to show as much as I can. Not always possible, though.
A banana ruler, did Kurtis send you one, they are very accurate, good to see you using it for layout work. 8mm grooving tool working well too!
I bought it from their store, but they did send me some extra goodies.
I still say I want a micrometer that reads out in thousandths of a banana :D

@@johnzenkin1344 Well, cnc won't do anything by itself.
That was one of the most stressful jobs in a long time. I don't know if it was the size or the price tag for the forgings ($70,000 for two pieces)
Yes. Both.
Nice work man. Those forgings are mint. What baffles me is the lack of scaling on the diameter tolerances.
Measure twice cut once, in your case it's magnified!
Nice job, from a non- machinist!!

I like the CEE Banana ruler jaja good one
OH LOOK!!! A banana ruler! AWESOME!
The weight a relatively small center will carry is amazing.
Yeah, it looks a bit scary.
Always awesome to see the turning happening on those huge parts.
Almost as awesome as those blue chips are beautiful.
I love seeing the chips turn blue. Such a pretty and satisfying color.
Giving the live center a workout! Good to see the precision CEE Banana ruler measuring instrument.
Loved seeing the banana rule from CEE Australia. Been watching you for a long time and love what you do and yes I'm from Tasmania Australia.
Yeah, I've been watching Kurtis probably from the beginning, so I thought I'll use their banana ruler in my video. They gave me a few pointers with all that TH-cam stuff, but I just don't have the time to spend on all the editing.
Got a fix8 on order right now... when I saw the gear on floor I thought I was looking at my old workplace :)

Sometimes, I'm looking at it thinking what would happen if it broke.
That second machine made these look like rc car parts!
Yeah, this thing is a beast.
The big lathe makes that thing look like a toy! 😯
I know, right.
Is that a cutting edge engineering banana ruler?
Sure is.
My Wife: Why are you watching work when you're not at work?
Me: I don't know . . .
When you start watching work at home you should seek help 😅
You gotta love that kenametal tool mate 👍 great video and thanks for sharing 👍
Takes a large set to do that work. Amazed a small footprint machine can hold that weight.
oh daaaaamn, using the FIX8... heaaavy cuts incomming !
From the sound of it it needed bigger tool holders and tools but you make do with what you have.
beautiful work!
Id love to see that big lathe in action! things'a beast!
It's not really my department, but I'll try to get more videos from that lathe.

Those are some big bananas!
Great Job !
Ahhh you know you’ve maxed out the travel of the lathe when you’re OD turning with a boring bar!
Yeah, that's why we've moved the rest of it to the Big Lathe. I finished all of the complicated stuff, though.
good job Chris Maj
You really end up going through more material in one part than Ive done in a whole year. that would be way too stressful for me.
This is Very big job ,job is Very beautfull,🇧🇷
Great workdone💯
I love the ruler lol
It's pretty accurate.
Couldn't afford a lathe big enough let alone the lump of steel so I'll just watch 👍
