Making a BIG Nut for Hydraulic Cylinder | Machining & Milling
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
😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😅😅😅😅😅 27:28
@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 ...
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 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
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. 😂😂😂
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!
Lots of people call themselves a machinist. You, Sir, deserve the title.
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 👍.
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
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.
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.
Ill bet you have customers that are very happy with your fabulous work. Sadly, here where I live(which was a renounced area in USA for generations of great machinists) mfg deserted these great minds and moved overseas. This, of course broke a chain of great mechanical minds. Keep up the great videos, Bill
Unreal content Kurtis and Karen, please don't ever stop making these videos!
hey mate thanks for watching & supporting!
Show of hands for people that want Kurtis to say 'That's not a drill........THAT'S a drill' on a video.
😂😂😂😂
despite watching your video after nine months I was amazed by your work, congratulations Kurt, a great job🇧🇷
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.
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.
Oh yes, a comparison please of drill types. Very interesting!! Thanks guys.
awesome thanks for the comment 👍
I actually never thought I would be watching 45 minutes of lathe video. Really nice video with details.
Yes I agree, my wife thinks my brain is addled whne I watch this, but never making it as a machinist and tool maker, I can see that I should have taken it up. Boy you have a nice collection of useful tools. Ex WW2 some?
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!
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/
Firstly Karen needs a little praise here her camera skills are in epic proportion, and Kurtis as always first class thanks guy's :)
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
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 KZhead you see more ways to do the same thing.
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!
two much talent for one man
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.
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.😁
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'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.
I'm always amazed at how small the actual cutter is on a metal lathe. (Not that it's not sensible; I understand why that is.) Your new drill's insert is an exception.
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.
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.
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.
Lovely shhavings from the drill. The view from the back of the headstock was impressive. Great. craftsmanship all around. Fun to watch you and your machines work!
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 😊👍
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 👍
I am not a machinist. But this was fascinating to watch. I'm impressed!!!
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.
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!
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
@@leehotspur9679 liar
Coming from me this will probably mean absolutely nothing to you but you my friend are a master at your craft. These projects are hard enough by themselves let alone while taking the time to place cameras, manage shots and edit for an audience. It’s a pleasure to watch someone who has completely mastered the tools he has at his disposal. My hat goes off to you sir.
... and madam. (since you are speaking of the camera work)
@@workingguy6666 and madam. I apologize for that oversight : )
@@budzillasohoski9858 : )
The bloopers at the end are the best!!
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!
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.
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.
Impressive super quality workmanship. You do quality work, be rightly proud of your professionalism.
Kurtis your skill with a lathe and all your other equipment always amazes me and Karen always does a great job with the 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!
This is impressive. Could watch for hours and I've never stepped foot in a machine shop. Thanks!
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.
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!
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.
I love how effortlessly this guy moves around these pieces of steel. He doesn't look like the strongest guy in the world. But he certainly works like it 😄
There's something very satisfying about a perfectly machined piece of metal
The new tooling is giving me drill envy.
how awesome is it!
@@CuttingEdgeEngineering about 2 bananas ?? 🤣
We had a 55 year machinist at a bottling plant. Everything is stainless. Guy was a maestro. Rip Alex
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.
Crazy to see how good you are with less than optimal conditions. You turned out some solid work.
Absolutely one of the very best regular KZhead productions, period. I love watching each new video. What a team! And, i'm not in the metal trade.
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!
Fun as always here with CEE! The attention to detail and pride in your work is always amazing. Great editing, great Homie, great outtakes, GREAT vids!
You must have a small fortune wrapped up in your equipment. Really amazing and such an art. Thank you for the stimulating video.
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!
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.👍☕
I'm amazed at your craftsmanship my old man was a fitter and turner by trade. Love your work. I'm a heavy diesel mechanic break down mechanic and I have used you every time Love you 😍
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 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.
Well the engineering is as good as we've come to expect, but the videography is next level. Thanks for posting.
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!!
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.
OK, saw the uncut Patreon version yesterday, but you can't get enough CEE vids 👍 You can tell it is a big drill when Kurtis puts his hand in the hole it has just drilled 🕳 😂 No pilot hole - that must save some time. All the best, Paul
Hey mate! You must be up there for #1CEE supporter we reckon 😏 Definitely saves time not having to pilot drill, really happy with the new bit of tooling! Have a good one Paul
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.
Came here for the machining, stayed for the bloopers.
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.
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.
I know what kind of work conventional mechanics is, respect for your work, this is art.
As a tool-oriented guy, watching a skilled, specialized tecnician work the heavy duty tools is delightful!
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.
The shot through the headstock was perfect. Reminded me of a tunnel boring video I watched once. Great idea and great filming!
Wow, just Wow! Thats not just a Nut, it is a thing of beauty, a peice of art...you are a true engineer.
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.
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.
Never saw one of those mega-drills before, but I like the modular construction and the swappable inserts.
Love the machining and welding. Love your puppy. And love your sense of humor. ❤️
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)
Got my beer, just finished a night-shift, great time for a Pommie, thanks Kurtis, longtime subscriber , Hope you lose the Cricket 😄I doubt that though.I spent a good few years working at the paper mill at Petrie in the early 2000's, stopped in Boondall, loved the place. All the best to you, Karen and Homie.
hey mate thanks for your continued support of the channel!
haha tough to lose to bazball, at least it's exciting and unpredictable.
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!
Brilliant piece of work. Always a pleasure to watch a skilled machinist at work.
I used to love machining 4140, always comes up looking a treat
Happy Friday to all from California!! Thank you, CEE for another FANTASTIC video!
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.
This was a thing of beauty. I just bought a small lathe. Can’t wait to try making some of my own stuff!
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!
Watching you guys from CEE has become a ritual each Friday morning here in Greenville, SC! Love your work. Methodical, precise, entertaining. Thanks very much.
Don’t forget Joe Pie who also has videos out on Friday. Kurtis works on the very large components and Joe machines the very small. Both exhibit exceptional skills!
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 😊
The headstock camera view was awesome. Watching the drill break through was so satisfying.
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.
Suggestion: instead of air disconnects, use hydraulic quick disconnects; such as you’d find on a tractor. The ISO 5675 ones aren’t too expensive and can be connected to the same coiled air line that you are using; however I would suggest getting the poppet-style ones as they flow better at lower pressures.
