Making a BIG Nut for Hydraulic Cylinder | Machining & Milling
Vložit
- čas přidán 29. 06. 2023
- We're turning a chunk of solid 4140 steel into a big nut for the EX1200 bucket cylinder rod. We are making the new nut to replace the one that was seized and gouged off the cylinder rod! In this video we show the step by step process of making the new cylinder nut. We are starting with a solid piece of 4140 steel bar. First we drill and bore out the centre of the material in the lathe. Then we cut the internal threads before finish turning the outer diameter. Next we use the super indexer in the milling machine for face cutting the nut into a hexagon before drilling and tapping a hole for the grub screw. We finish the job by machining the new threads onto the EX1200 cylinder rod to suit the big nut.
In this video we are using:
- Hafco TM-26120G Centre Lathe
- Hafco BM-63VE Milling machine
Missed the first video where we gouge the seized nut off to save the $20K cylinder rod?

G'day Kurtis, Karen and Homey great video and have a great weekend mates
Ciao non hai pensato di mettere lo stelo bloccato sotto la pressa e svitare il dado ferma pistone scaldandolo? io facevo cosi

@3:02 Mentos ???
Love it! Your customers are lucky to have you.
A video comparison of the drill types would be much appreciated.
awesome thanks for the comment 👍
Haas has a good video on that
@@printgymnast368have a link to it? I'll watch both
@@CuttingEdgeEngineeringno problem, you asked, seemed only polite to give you a definitive response.
It would be really great to have a review of different drill types used for production work
You guys should have a stamp or laser etcher to put your logo/trademark on manufactured parts..the quality of work you both do is a pleasure to see.
yes he should. why not blacksmiths have one.
oh hells yeah. gotta put yr mark on it, repair date and number etc would be helpful Im sure. He might need an apprentice not just a safety officer
Kurtis does have a stamp for the machine work that he does
@@mattymcsplatty5440 Kurtis prefers to work alone, because he has said before that it cuts down on mistakes, etc. and that if any mistakes are made, he is the only one at fault
It's good marketing, and potentially useful for record-tracking when so much work is "one off". But with most of the work then going out to be slathered in yellow (occasionally orange) paint ... anything much more delicate than writing "CEE" and a reference number (YYYY/MM/Invoice# or similar) with the welder is unlikely to be visible through 3 coats of yellow and 2 inches (bananas) of mud ...
Lots of people call themselves a machinist. You, Sir, deserve the title.
I have not seen a couple who compliment each other like you two.You both have exceptional skills,Curtis with his mechanical skill and craftsmanship a cut above.And Karen with I assume office and all that goes with that job and then making your channel every week look as though a professional film and edit company were behind the scene.Not to mention how hard working with your spouse could be.Very cool.So nice to see.
What you do with this steel leftovers
@@mshk999 Scrap buyers all over
Wow that internal shot of the drill breaking through was absolutely stunning. Excellent ❤
Karen's videography is top notch! Came down to the comments to thank for that drill breakthrough.
Yup was gonna say the same.
Trippy
Woah! Spoiler alert
FOr those who don't know: if you are wanting a precise hole position, or if you're drilling a deep hole with a spade drill, it's crucial to provide a close-fitting starting bore deep enough for the guide surfaces at the OD of the insert to be fully supported before the central chisel edge touches the work. For deep drilling, high pressure coolant is advisable, otherwise a drastic reduction in feed rate will be necessary, with multiple withdrawals to clear chips.
Wow! The shot through the headstock bore is FABulous! And this episode has so much going on. Thank you !
Yay glad you are enjoying it 😊
Reminded me of those clips you see of tunnel boring machines breaking through.
I was thinking it looked like some psychedelic '70s sci-fi movie special effect. Lol
@@bumblebeebob "Time Tunnel"!.. If you remember that, odds are you spend as much time as me looking blankly into the fridge.
@@gav2759I completely expected that to be a time splice. 😂😂😂
Visit 2 tonight. It really is a great recovery my friends. You saved the owner thousands of $. It takes me back to younger times before retiring. I would have had a great time working for you folks. Every day you never know what is coming in the door day to day. Take care and see you next post eh !
I am not a machinist and have no desire to become a machinist but I really do love watching the manufacturing process. Great Job Curtis.
Even after watching 100s of your videos now... I'm still amazed how Kurtis can find perfect centre when lifting any object. That's a superpower in itself!
I was thinking the same thing
I think he marked center from an earlier lift
You could say... its UPLIFTING.... ok I will show myself out...
Karen's camera work is great! The shot of the new drill coming thru the end of the metal looked like a shot off a sci-fi movie!!!
Scorsese himself would’ve been impressed by that shot. One chance only.
@frankblack1481 yeah she kills it!
Great camera and editing to accompany equally great machining. You should suggest the customer use some anti-size paste on the threads to try and avoid another frozen joint.
I started machining, if you could call it that, when my step father bought a primitive lathe, belt driven, without any scales on the cross side, some 65 years ago. It was needed for a home built amusement size railroad that wore out bronze bearings every season. Great fun for a teen age kid.
I second that!
She is the best!
You are a master at your craft. I work in industrial machinery, so I am familiar with the amount of work this involved and the attention to detail. Something like this, I would be holding my breath every second. One miss chuck, one broken bit, one lathe malfunction and you have a heap of expensive iron to deal with. Amazing!
There are so many satisfying moments in this documentary.
From the unboxing of the blank and new upgraded parts to the satisfyingly precise assembly of the drill head and of course the machining itself. Great to see a craftsman at work.
Unreal content Kurtis and Karen, please don't ever stop making these videos!
hey mate thanks for watching & supporting!
When I was a boy, England was full of places doing this kind of engineering. I don't think there is much left now. Good to see these skills are still around elsewhere in the world. Fascinating to watch.
I can assure you theirs plenty of stuff still being made using a lathe in the uk, I test fire alarms and see awesome stuff being made every week.
I know of at least 10 engineering firms in my small town. Not sure where you are but I can assure you the trade is still alive and well.
I live in San Diego, Ca. USA. This kind of stuff is being done all around me. Mostly small stuff inland and large scale stuff typically by the coast with ship building and repairs.
There are still some in UK but most are CNC machinists & couldn't do it manually
At least here in Brazil there's too much CNC manufacturing and jobs. So conventional machinists are quite rare and valuable here.
I was fortunate enough to have done this kind of metal work at school as a profile. And a few years later, Im admiring such profession more than ever. Beautiful work lad.
You are proud of your skills, and the jobs completed. I worked as a engineer, in the UK for 44 years, so I appreciate all this. Thanks for a great engineering video. Peace brother.
Oh yes, a comparison please of drill types. Very interesting!! Thanks guys.
awesome thanks for the comment 👍
Outstanding workmanship. Karen gets extra credit for her superb camera work. Awesome detail of seeing the drill penetrate the stock in the chuck. Thanks as always for bringing us along.
As a first year apprentice, all of this is very important, interesting and good information. Any videos that can expand someone's understanding is always going to be worth it. Especially seeing as how much trades have been dying out over the last decade.
I'm amazed you can do a combined ~12 passes cutting threads on both ends and they end up threading together so smooth! Nice work, man.
Honestly doesn't matter how many thousands of threads I've seen cut, turned, or roll formed using high speed machinery it still looks like witchcraft to me. Doesn't matter what you are doing Kurtis, it's great to see that no matter how simple or complex the job at hand, you still apply the same high standards to it all.
And big props to Karen for her excellent videography and editing. Still finding yet more new ways to both tell the story and bring us along for the journey.
I wish I had seen your comment earlier.
I agree with you, even for something for internal use everything could pass as an artwork. No chatter marks or weld splatter when finished. Nice to see some will still take the time to do something right, and willing to continually reinvested to keep up the standards.
This quality of workmanship and editing is beyond the top of the charts. Absolutely impressive.
Awesome isn't it, mesmerising
Wow great bit of gear there. Very entertaining and educational. Thanks for sharing your work. Following from Sydney Australia.
Excellent job !
I admire your incredible machining work, I'm in the USA and worked as a machinists for years. I give you a ten thumbs up young man. Love your sense of humor and your puppy. Steve in Montana
I like the New internal cutting tool holder for machining the nut & cutting the thread inside & outside on the shaft. Amazing Cooling system going along with the cutting huge drill size. No splashing or missing up water all around, very clean & precise cooling system. High thumb up, for this smooth & accurate job. You have a very nice shop.
I am a mechanical engineering student, I really enjoyed and appreciate your videos, they have helped me to learn a little more than what they teach in school, thanks Karen and Kurtis. I live in Mexico so I start my day watching your videos 😀
That why I like the "University of youtube" you learning more ways to do things. when you in a classroom it only one person show you you do not know if the are right or wrong we just do it because the say so. With CZcams you see more ways to do the same thing.
Doing machining is one thing, and then also filming it so nicely with a walkthrough of the process = INSANE hard work 👌
@@notfiveo😂
His wife is a great videographer. I appreciated the shot from the end of the lather seeing the bit punch through!
Watching you and the machines work makes my mind happy. Not much does these days, Thank you.
@@hickfarm Yeah if you ask me that was one of the coolest shots!
TOOL PORN! Watching you unbox and assemble that bit and all the components was pure unadulterated smut of the very best kind!!!!
MORE, MORE!!
I have no idea why this is so endlessly fascinating but myself and 67, 000 other viewers agree.
You should re-name your channel XXX Engineering 😂😂😂😂
My favorite part of the porno was the big nut at the end
Big nuts seems to be a recurring theme on his channel! Great machining and video work - as always.
Homeless features in that regard as well. Deez nuts.
nuts take a lot of abuse and are high wear, the massive surface area of the threads make them a hotbed for wear and tear and galling as well as corrosion, a weird shock can strip threads and cause other issues too... its not too surprising nuts and broken threads make up such a huge portion of the work done as they are typically the weakest point
Homeless is very modest, he wouldn't want to be grabbing the highlights. (despite his doo dahs).
@@Simon-ho6ly Ahhemm ...It was a joke around the historical and humorous references to Homie's spectacularly 'big nuts/nutz' and other equipment.
@@Simon-ho6lywoooooooooshhhhhh/
Karen, your cinematography, camera angles and editing skills improve every week!
Very impressive and always interesting.
As always.
Massive Respect from Aotearoa, New Zealand

PS..... GO THE BLACK FERNS!
Fifty years ago I worked as an Estimator for an engineering and iron founding company in Alexandria in Sydney where we made all the valves for the MWSDB.
The foundry was in Alexandria and the major machining was in Smithfield and I loved watching the machinists turn great pieces of cast iron into precise components, my job was estimating the costs based on weight of iron and machining times. I totally enjoyed watching your work, seems like all the skills haven't been lost, well done.
Wat i love the most about this video is that we get to see every little detail thanks to the lady working the video,this type of thing is not always seen in many videos,the nut is outstanding,I can't wait to see what's next
It's very apparent watching you that you're the shop owner, you are paying for parts and machinery. You are very careful and deliberate in your movements, locking in bits, etc. Fascinating stuff!
why pay for roll over protection, on a forklift, if you aren't going to wear a seatbelt? That is a waste of money.
@@wadestanton BS, Its for overhead protection Falling articles when loading or unloading Gets yourself on a forklift course

We had a 55 year machinist at a bottling plant. Everything is stainless. Guy was a maestro. Rip Alex
Beautiful, simply beautiful! I have done a lot of different things in my life, and now I am a self-employed, largely self-taught carpenter/handyman, but if I had my time over again, I think I would like to train as a machinist. My eyes are not good enough anymore, and at 60 it is a bit late to retrain, but I always loved this stuff, and it is a joy to see a skilled man at work.
I'm a finish carpenter, not a machinist... but I found this video fascinating! I admire your proficiency in your trade. Excellent workmanship.
Firstly Karen needs a little praise here her camera skills are in epic proportion, and Kurtis as always first class thanks guy's :)
Using an adjustable boring bar as a fly cutter, I've never thought of that one! And yes, a drill comparison would be great please.😁
I could watch this all day. Machining is SO BEAUTIFUL!!
And the excitement I felt when you opened the new toys?!?! Wow, TOTAL beauties!😃😃😃
I love your videos. The camera work and editing is excellent. The panning starting at 9:35 - where the drill exits the work - is one the best takes I've seen in any workshop videos.
What i always find amazing is the amount of work you put into making these parts and it's still cheaper for the customer than buying OM parts. Great vid, have a great weekend guys o/
Because OEM suppliers are greedy funkers..
Just look at Lambos that are using VW parts, which are a bit cheaper, but the moment it is for a lambo the price tag tripples all because of name..
One would call it, name greed..
@@Cent51The irony of that being Lambo was formed because Ferrucio clocked that Enzo was charging a fortune for tractor clutches because they said Ferrari on them 😂
@@Cent51ts because its a single point of communication, problem solving, quality control, sourcing material/ parts.. For OEM, you start with the ordering process, you have a person go onto a system to order a part, that order is then passed onto a picker to then pull off the shelf, package it up and then send to the distributor for your location. They then have a person enter it into their system then contact the customer saying they have the part and they are sending it to them..
Its an absolute cluster fuck. There is more to it but thats the basic structure.
Time is money. Leave an EX1200 stopped for a few days, and you might also need to stop a few trucks, all in all, you can lose upwards of 50K pretty quickly, just at the mining site. So paying the OEM rates becomes a smaller loss.
When the mining companies have access to enough spares, it's a different story, then machinists have the time to replicate a part and avoid the convenience fee.
Most OEM's don't see machining specialists as competition as strange as it might seem, often times they have to work hand-in-hand as the OEM 's will hire machinists to refurbish older units taken in trade.
@@Cent51mat armstrong had a belter find when rebuilding his murcielago, lambo wanted 180 quid for 1 side light repeater, but they are ripped straight from a ford focus and ford sell them pack of 2 for like 6 quid. Its absolutely mental how greedy they can be!
A comparison of different drill types would be interesting and since you’re one of a small handful of people who can make that comparison we’re hoping you’re up to it. Thanks for all the wonderful work you do.
Just found this channel and as a young machinist apprentice you are a book of knowledge my friend,thank you for the videos,your time, and your wisdom.i like your big boy machines a lot.very cool.
That Sir is a threading job well done and done right ! My Dad (if he were here to see it) would say “that’s really nicely done” He had an old South Bend 13 out back the barn where I grew up, taught me to how to turn and center a rod, and cut a 3/4 11 thread on it. I got tired and wanted to see the U.S.A. , so I drove truck here outta S Tx. for 28 yrs. He passed 32 yrs. Ago, now I’m retired and working on old Lathe , maybe I can pick up where I left off. Nice camera work; steady, sharp & clear and get right in there and show us how it’s done 👍.
It's 1am in the UK and I've been glued to this demonstration of engineering skills. Absolute perfection......and a lot of talent.
Same here... but it's 2am in France! Mesmerizing work! :D
@@dollyvintage8558rip to you
1:15 in Canada, i told myself I’d only watch the vid of him taking off the nut but here I am.
So shiny and precise. Craftsmen like you guys are what keeps the world’s industries producing. Thank you.
I really don't like the chatter that the drill was showing ,hard on the equipment.
This whole rod/nut process was a pleasure to watch and looked liked pure pleasure to work on.
You must have a small fortune wrapped up in your equipment. Really amazing and such an art. Thank you for the stimulating video.
Hi Kurtis,
Love your videos. I like how you explain things in great detail! I would love to see a comparison video about drill bits.
thanks for the feedback 👍
That's a lot of material hanging out of the tail stock! I see a lot of flexing in the shaft for such a heavy extension/holder. I didn't think you liked that on previous videos I've watched. It'll be interesting to hear your comments!
Great job Kurtis, really methodical. We used to dislike not being able to get hollow bar for jobs, we called it "Manufacturing Swarf", especially on large jobs. The 90mm spade drill done a stirling job on the boring. Thanks for posting, and great cinematography by Karen, stay well be safe 👍
The quality and value of your productions are outstanding! The shot at 9:30 was top-notch and I love the quiet inputs from the camera person.
Thank you 😊
I am not a machinist. But this was fascinating to watch. I'm impressed!!!
The CEE video production quality just keeps getting better. The new tool unboxing makes a great mini-feature in itself.
Wow, thanks! Glad you enjoyed it
Great comment and I for one totally agree!
I have been watching your videos for a while now and have never lost interest in any of them. Your filming and how your better half captures all the things you do and say is excellent. I don't really know jack about your business but find your expertise and work quality all top-of-the-line. Also, love your dog and am happy to see all the love the three of you share. Please continue with what you are doing and don't change a thing. 👍👍👍
Wow, thank you! It's feedback and positive comments like yours that help us stay motivated to keep up with the videos 😊👍
The machine operators and mining companies are fortunate to have such a bright engineer in thier area , you know your craft !! ,great camera work by your wife , great safety work from your cool dog , a real dream team.regards from south wales (uk)
After 35 years in Ship Repair and Engineering (UK), I have seen alot of Machine Shop work, including multi tonne Shafts. I must admit, that was, done perfectly. You are are a highly skilled Craftsmen, no doubt about it. Well done.
I'm not even remotely capable of doing this kind of work but I am uber grateful for guys like Curtis taking the time to educate the many people that want to follow in his foot steps.
he is doing all jobs half a prise!
Truth ....15-20 years ago you couldn't pay to watch over the shoulders of masters like this . Now I can do it with a cup of coffee on the tolet. Thank you for letting use watch you be a master of your craft.
Kurtis your skill with a lathe and all your other equipment always amazes me and Karen always does a great job with the video
Brilliant piece of work. Always a pleasure to watch a skilled machinist at work.
Crazy to see how good you are with less than optimal conditions. You turned out some solid work.
I'm just totally blown away at your knowledge and abilities commanding the use of such large and complicated machining equipment. I'm sure you have way more work than you can keep up with. You don't seem old enough to me to possess the techniques and prowess that you display, you are a very smart young man. It is very satisfying to watch you work on the projects in front of you along with the fine videos that your wife create for you. You are very fortunate young fella. Kudos aplenty my man. 👍👍👍
"Powers and abilities far beyond those of mortal men!"
@@billsinkins361Ha ha nailed it!
You see the end result but you never know what it takes to make these specialized part’s. The patience it takes to achieve the final project and to exact specs gets has my respect! Having it condensed into a video with the high quality filming only proves the attention to detail you both have! Like they say it’s the tool that makes the money!
It would be fun watching a video of what you sent in to be fixed fixed. I would find that super interesting. Machining and tooling is an art form.
Love the machining and welding. Love your puppy. And love your sense of humor. ❤️
Absolutely one of the very best regular CZcams productions, period. I love watching each new video. What a team! And, i'm not in the metal trade.
Show of hands for people that want Kurtis to say 'That's not a drill........THAT'S a drill' on a video.
😂😂😂😂
Resting the nut on the tailstock. Little move that demonstrates your high level of your experience. Great stuff!
I'm am mechanical engineer. I worked at a tool and die shop designing solutions to throughly buggered tooling as an internship, and then designing machine tools just out of college and its fun to watch a experienced machinist solve problems. I just found your channel and subscribed.
Again the quality of the workmanship and Karen's videoing is way beyond compare. Thank you both, I would not miss any of your uploads.
Of all the things you do, cutting threads is the most intimidating for a non machinist like me. Would be shitting bricks every time I set us the lathe and started to cut threads on that giant piece of steel. Thanks for sharing and another great video. And the drill type comparisons would be very interesting.
This was a thing of beauty. I just bought a small lathe. Can’t wait to try making some of my own stuff!
You really do awesome work. I’m impressed. Keep up the good job. Your show is very very educational. I can’t tell you how much I learned by watching you. Thanks again.
I would love to see a comparison video on the different drill types would be neat to watch. Beautiful job you too keep it up.👍☕
Kurtis - You are amazing !!!! My jaw just drops to the floor in awe at the craftsman ship you possess and astonishing work you do. !!! The making of the nut from a round block of metal was mesmerizing to see !!! And then it spun on the rods threads as easy as eggs in a pan of butter !!! Watching you and Abom79 do machining has me glued to the screen every time !!! A handshake and then my hat is off to you for such superb quality work !!!!!!!! 🙂💯👍👍👍🏅
At the 8:05 mark and onward, I held my breath when the tool started jumping around. I thought it was going to grab the work piece and fling it on the shop floor!! I feel better now!!
From the United States, love your videos.
Isn't it strange that we watch each other work in our spare time? I change big rig truck tires and fluid filled farm tires. I enjoy watching about the drills and tools used to work in mammoth cylinders. This is my second video watching and I am hooked already!
At 33:49 Kurtis gives an excellent explanation of why he does not re thread the old nut. Thanks Kurtis, you leave no doubt as to your thought on this.
Because he arc gouged it into pieces maybe
Greetings from Ohio once again. I’ve been waiting for this one to be posted. I’m intrigued by the new tools and the whole concept of spade bits for metal. Also always impressed by machined threads that don’t gall up. Good job my friend.
I’m stuck at home unwell. This was the best medicine ever. Superb skills, I’m in awe of what you achieved. Thanks.
WOW. That is some serious machining right there. Thank you for showing us.
Well the engineering is as good as we've come to expect, but the videography is next level. Thanks for posting.
The new tooling is giving me drill envy.
how awesome is it!
@@CuttingEdgeEngineering about 2 bananas ?? 🤣
Wow, just Wow! Thats not just a Nut, it is a thing of beauty, a peice of art...you are a true engineer.
The headstock camera view was awesome. Watching the drill break through was so satisfying.
It's cool to see a hunk of steel turn into a working piece of equipment. Love watching this channel and watching the master at work. The videos are top quality when it comes to how they are put together and edited too. Cheer from Florida!
Love the fact that you do everything you can to save your customers money, when I was in college my teachers always used to say to take as long as possible on jobs and charge according to the time scale which I always disagreed with. Another fantastic job done by yourself kurtis you're a top bloke fair play to you 🤙
You definitely undercharged the customer. That's an amazing amount of work, tools, and expertise. Nice! Also, that dog was my favorite part of the video. Cute dog!
Look at those awesome chips. I worked in a Tool and Die shop straight out of high school. I can still smell the coolant and hot metal. Love that.
Quality work, as we’ve come to know expect Curtis. Would love to see a comparison of the drill types. This sort of educational content is hard to come by for those of us not in the trade.
Hello Kurt and Karen, I hope all is well in Australia. The teaching video was awesome. The videography is so good I am incredibly amaze how good this video is thanks to both of you and homie. Take care, thanks 😊
I didn't wake up this morning thinking I'd sit through 4 5 minutes of lathe and milling wizardry, yet here I am. Brilliant video. I feel like I'd really like to pop by and watch this in person. Nice one.
I know nothing about engineering or machining. I watch Titan vids. But this guy is brilliant. I'm just binge watching his stuff. Great skills. Thanks. Much love from the UK ❤️
Wow Kurtis that turned out to be a great end product. That’s amazing how that new drill works. Certainly going to be a time saver. Good job Karen for showing us all the different angles and I just love your giggles.
Brilliant!... I am a software engineer working in the security domain. I so appreciate watching and listening to an expert perform and explain his craft. Kurt's is top drawer!... I so look forward each Friday to viewing your methodical work. It is so satisfying watching a master ply his craft!
Great production value mate. I was captivated! You are the Mozart of machinists.
Definitely worth making a second cup of coffee to see this done. Truly amazing! I wonder how many people in the world could do a job like this? Never seen the likes of doing something like this or realized it could even be done...BRAVO!!
Never saw one of those mega-drills before, but I like the modular construction and the swappable inserts.
I just binged your channel and I cannot tell you how impressive your attention to detail is. You are amazing at what you do and a pleasure to watch. Looking forward to whatever comes next.
That was a cool shot looking in from the drive end of the lathe when machining the inside of the nut, love the creativity!
Love your confidence about the grub screw stopping the glan nut from loosening itself. I just had a cut and shut done on my bucket cylinder for my SK70SR Kobelco because despite the grub screw being pined twice to stop it undoing - the frigging thing all let go and she unwound until the glan nut was hammering the end of the cylinder and she gouged out the cylinder wall to the point hydraulic fluid was bypassing. She's only a 7 Ton machine and it cost me $3,300-00 for the repair. No replacements available in Australia and getting one new from Japan was $6K plus shipping from Japan. I am in Newcastle NSW so she was a bit far to get you to do it up there in Queensland - ah well boys toys are expensive to play with.
But I Luv your work and your channel - keep up the good work!!!!!!
