Machining a BIG Cylinder Rod for Mining Excavator | Hitachi EX1900 Boom Lift
Вставка
- Опубліковано 15 жов 2024
- We need the BIG Lathe for this machining job! We are making a new cylinder rod for a Hitachi EX1900 Mining Excavator boom lift cylinder. The chrome rod is worn out, it has rust spots and fatigue fractures, so we are going to make a new cylinder rod. This shows the step by step process of removing the eye off the old rod, machining up a new rod and welding the eye onto the rod. First step is machining out the weld joint that holds the eye onto the old rod. Once we remove the eye off the rod we also press out the damaged bushing in our hydraulic press. We then start machining up the new cylinder rod by rough turning before finish machining the end for the piston and nut. We cut a 4mm thread pitch external thread for the nut before flipping the rod to machine the other end. We machine and drill a hole before fitting and stick welding the new rod eye in position. The eye is welded on using metal cored wire before press fitting the new bronze bushing. We finish the job by cleaning, wrapping and strapping the new rod and send it on it’s way to the customer.
In this video we are using:

I like best learning from Kurtis and Karen, each new job, we hear the cuts, we hear the instruction, and Karen brings it all alive.
Have a good weekend Karen and Kurtis
Great work on the work that go's into each video Homeless has gotten better in the video dept he has great views .. neat to see what a dog sees love the slowmo ..
Bloody Brilliant!
was wonderimg, heat effects alot, must have been a long coool time
The best part of this whole channel, aside from Homie and Giggles, is that we're watching a master of their craft who can achieve and expects near perfection from himself - Every. Damn. Time. It's more than a little bit humbling.
wow thanks mate for saying so, i just like to get in and give it a go, I've never been one to half ass something always use full ass 😂👍
@@CuttingEdgeEngineering sounds like another t-shirt "always use full ass"
@@alargecookie never half ass two things when you can whole ass one
"Giggles"....lol
lets not forget George
"It's 3.7m long, or 12 banana leaves" Curtis putting things in an understandable perspective
got to keep things accurate 😂👍
Yes, I liked the banana leaves. It's nice to keep the old units alive. Furlongs, firkins and banana leaves.

Aside from the skilled engineering in these videos can we take a moment to appreciate the level of expertise in the camera work, editing and professional level of presentation shown in every video. This the level ALL UA-camrs should strive to achieve. Thank you for all your efforts. This grumpy old fella appreciates the efforts you put in.
hey mate thanks very much for the great comment we appreciate it!
I liked the clock placement whilst welding!
Yes Steven Booth I do mean you.
Karen truly is quite skilled and has artistic talent with her videography and her editing!
I cannot imagine the capital investment required for this type of business. Can you think of turning away clients because you don't have a machine big enough. So you have to gamble on how much machine you need. That's got give some sleepless nights worrying.
I have never machined anything in my life. I don't even know how I stumbled upon your channel. I am just fascinated by the sheer level mastery over one's craft exhibited in these videos. Your skill and expertise are inspiring to me.
Whe you used to do it, it's like you are doing door hinges. First time it's scary but third time it's routine.
Remember my first time machining drive shaft for ship oil tanker, oh my Good i was scared but when it was finished i was so relieved.
it's my profession, and even in my holidays im watching this stuff lol
Yet this bloke is being displaced in his own homeland by his government with endless migration of scab labour to drive down the living wage so the megacorps continue to get filthy rich and the poor stay poor. From 100% in 1979 to 37% in 2012.
Likewise, it's fascinating. I've been in mining for over 20 years and never knew what was involved in these types of repairs.
Karen, Your camera work is fantastic but the split screen is above and beyond. Thank you for the hours I know this takes! Oh and Kurtis, you're pretty good at what you do too.🙂
The split screen is great.
I wasn't financial free until my 40's and I'm still in my 40's, bought my third house already, earn on a monthly through passive income, and got 4 out of 5 goals, just hope it encourages someone that it doesn't matter if you don't have any of them right now, you can start TODAY regardless your age INVEST and change your future! Investing in the financial market is a grand choice I made. Great video! Thanks for sharing! Very inspiring! love this.
I love the fact you stressed on the words grabbing opportunities. But how will one know what to focus on, last year I invested into gold and got nothing meaningful.
0:49 This is one of my favorite things about this channel. The little nuggets of information about just how and WHY these parts are used the way they are are solid gold.
I am more convinced than ever that Kurtis' Superpower is being able to see the centre of gravity of anything he is going to raise off the ground. I was wondering about that tool post, not up to CEE spec. Great work on the filming and editing Giggler. Thank you Kurtis, Giggler, and Homey!
He may be that good, but I think the one with the superpower is Karen with her editing.
Was thinking the same, a remarkable knack of finding the centre of gravity every time, very impressive!
I'm a millwright and move stuff like this all the time, you kinda learn to see the center of gravity, he does this daily im sure he has learned it
Jim Sim... as tradesman joinery cabinet maker old school .. it is a pleasure to watch someone who knows what he is doing using good large equipment with pride in the result you deserve success in your business good video thanks my brother a ships 1st engineer is also impressed
I love the split screen shot of you at the controls and the view of the tool cutting. I really puts into perspective the hand-eye coordination you need to operate.
Fantastic videos as always. Have a great weekend you three!
glad you liked that!
@@CuttingEdgeEngineering Yeah the split screen stuff is really cool! I think people definitely want to see more of that in the future!
Agreed in the split screen, that is great editing and helpful for viewers.
One shot looked like it would have been better with the screens reversed, so the feed directions made more sense.
Agreed. More please.
Definitely more split screen please.
4:56 I was VERY curious about this, so thank you for taking time to explain how sturdy that live center really is! 👍🙂
Glad it was helpful!
@@CuttingEdgeEngineering Oh yes, I had the same Question and now I have the answer!
@@philho122 It just doesn't look right eh? That is a hella lot of force on one small point all stabilized by a bearing. It simply impressive.
@@TheStealthbob Must be one heck of a beefy bearing in that center
I'm a retired heavy-duty / equipment mechanic. I stumbled upon this channel as well and been fascinated! About the quality of his work. The way he takes care of his shop, his equipment, attention to detail and concern with the customer's expense. The fact that he does it all with no other shop Personnel was amazing. He has his safety coordinator, his dog in the shop plus his supervisorial staff, the birds. They do a great job!
I am always amazed at the level of creativity shown in the vodeography and editing, right on par with top studios anywhere. Yeah, Kurtis does the machining, but, the videographer brings it to life. Always perfect lighting, focus and emphasis on the action. Thanks to both.
wow thank you so much!!
@@CuttingEdgeEngineering You're welcome, and all this without a team of writers, directors, lighting techs, audio techs, or editors.
Totally agree but I think the safety officer needs a steady cam many thanks for superb videos
1000 percent agree with this statement!!!
@@johndavies2396 The steady cam was a great innovation, but the video focus & frame stabilizing whatever the real tech name is, all done electronically, is simply amazing & getting a real workout from the dog's collar. Also, the on the job training of the video-ographer has shown excellent results!
As always, your videos are so interesting and informative. You seem to make things with so much ease and accuracy. The camera close up work is amazingly so vivid and clear. Awesome work Karen. Love watching both of you work, time flies by when I watch your videos. Keep up the great work both of you. PS: I love watching Homie run around with the camera mounted on his back harness.
hey mate what a great comment to read, glad you enjoyed it!
It's people like you that keep the world moving! Hard work and the personal satisfaction of a job well done. Fantastic video as usual!
The brass shims/chuck inserts are getting their workout. Fabulous editing and camera work. The story is being told with nary a word yet so riveting and engaging. 🙂
Glad you enjoyed it mate
Yea.got those brass shims done just in time.
Aren't they bronze?
@@jkr3008 Brass is softer, less brittle and cheaper. Check the video before this one.
@@c4t4l4n4 ok, I'll chek it out.
But I used to deal with bronze bearings so that's why I asked
45:06 Gesundheit! Outstanding work! So impressive how Karen continues to elevate the videography. You have already achieved such excellence, yet you continue to surpass previous masterpieces on a regular basis. Thanks to BOTH of you for sharing your work with us all.
After all…. She is “UA-cam QUALIFIED”… she does great work.
The top quality, and pride you take in every job inspires me to do the same in my career. Most of the crew in my shop couldn’t care less about their work, and management is too afraid to crack down on them due to a number of different reasons. It’s tough to keep my head up some days, but seeing people around the world who care and are a great learning resource helps tremendously.
Good shout mate, go into work and show them how its done!
Nothing better than an big rod in the big lathe! It is probably the most iconic thing about your channel. You must be relieved when this project was done and out of the door. I was also kind off nervous about making a mistake and screwing the material. But you handled it really well as always!
It is all video editing. One rod costs about 2000dollars. He said "about 10000" - so it was 5 attempts to succeed.:) NOT
You guys get better and better at showing us how it's done! I really like the split screen section (superb editing Karen), real time clock that shows Kurtis doing an amazing continuous 2 hour weld, and of course the awesome Homey Cam so we can smile even through the break 👍👍👍
im 53 now and apprentice trained in most machining aspects. (lathe/mill/cnc variants) after spending 20 years in the profession i left to join the Military and after much stress and a good sized nervous breakdown im happy to be back in engineering again. nothing quite this size , but its still brown trousers time when you're working on
supplied billets or customer parts as opposed to stock. thanks for this guys , its refreshing to see large engineering again, ive missed it and appreciate the skill and time involved. also great editing ang camera work too.. everything is spot on.
If ever there was a team, you and Karen are it..! Your skills and experience make what you do look so easy and Karen captures it so well and puts out a superb video for us to marvel at. That big lathe performed beautifully and handled all that mass with no apparent problems. I love watching big machines doing precision work by people who clearly have been there before. Can't wait for next Friday to arrive. 🥰
As I am retired Electrician who loves watching other tradies who use their hand skills well and efficently. I have two lathes, a mill drill and a TIG and Mig welders and enjoy making things in the shed. A few more projects then back on to my hot rod.
It’s a tossup as to what’s the most impressive:
Shop’s strategic growth and financial planning acuity; Kurtis’ engineering, machining, welding skills; Karen’s impeccable production. If there are awards for UA-cam production, Karen should get one. Thanks to you both! I so look forward to Fridays. Michael from Texas, USA.
This
A joy to see the thread cutting and the old school double check on the pitch with a sharpe :-)
What I like about what you show is the added feeling of consequence if you get it wrong, it is more than just content.
From a machinist point of view it is more engaging and relatable.
Informatively presented contend as ever.
great comment thank you!
Man that is one hell of a rod, I see Karen is getting fancy with her editing and Homey is also helping out great work from all of you.
Thanks for explaining the reasons for the cylinders orientation civil/mining!
Ah yes nothing like a BIG ROD first thing in the morning.
🫡
Isn't that what she said? 😁
@@robertwest3093 could be that's what he said🤣
Nothing like watching a big rod being shaped before bed
Really, how old are you...
Спасибо. Как всегда все на высшем уровне, в том числе и работа оператора.
cмотрю его больше года. перень с руками из правильного места
Watching that threading insert go to work is terrific. Amazing to think of a huge piece of metal like that being turned into a big bolt.
Love “Chopper”, it is so cool that every time there is an issue you just seem to make the required tool for the exact situation.
right on!
That`s the benefits of knowing what the hell your doing.
@@CuttingEdgeEngineering I call it 'getting shit done' There are some trades people who can get shit done You are one of those people.
I know that he makes parts and tools all the time but it still amazes me that he can make parts and tools. If I need a new hammer I have to run to the hardware store. 😂
I'll sometimes spend a couple hours making a bespoke box trammel to mark one or two lines, spent a day making a jig for a handful of otherwise tricky cuts more than a few times. Makes the difference between average and excellence.
Nice split-screen shots and great super-slo-mo work, Karen! Homey's GoPro works well, as long as he remembers to duck going under things. Nice to see a thread cut the proper way, as I was taught 64 years ago.👍👍👍
I used the compound at 60 & a thread chaser. I believe his compound is set for stability, only using the cross-feed for depth. Also, reversing all the way back, not disengaging half-nuts, to make the next cut, was that because of no thread chaser or not trusting the ;new' machine?
I’m surprised discovery channel hasn’t approached you yet pal for your own show, I’ve never watched something so much. It’s really good watching someone who is so professional and dedicated to excellence. Good job man.
I've watched a lot of your videos and believe this one has the best camera work and editing of all of them. Congrats!
Kurtis, I know you prefer to work alone (and I am continuously amazed that you can handle such large work by yourself) but please think about the fact that your fabulous knowledge and experience really needs to be passed on. None of us are promised tomorrow. There has to be someone who would share your work ethic and determination that you could bring into your shop.
Wow thanks for saying so, glad you enjoyed it! Kurtis likes to think he's passing that knowledge on to many thousands of people around the world
@@CuttingEdgeEngineering And he's not wrong in that opinion. But having a trusted assistant would allow Kurtis to delegate the 'grunt' work and focus on the stuff that he does best. For example, his talents and time are wasted sweeping the floor. Just my opinion.
@@gregorywells7905 I would love sweeping the floor in this facility lol
Greetings! I will not be surprise if your videos are used as repair guides or something! Yes, tools and materials, preferable by specialists may be different, but style, approach and support (Karen and Homie, this is for you!) - that's the stuff! Keep it up!
P.S. Sorry for bad grammar, not my strong side)))
hey mate we have had people in all different fields tell us they use the videos for training
you know the production value is excellent because you don't even think about it when watching. just enough time to focus on what's being done but not choppy, just enough sped up video to get the job done but not a bit more. Great angles and then just a perfect amount of normal, 'looking over your shoulder' camera angles/footage. Seamless. Kudos
Really love this content! For me does CEE Fridays highlight how amazing engineering is, and how much more these jobs should be appreciated... Yes university is great, but jobs like this should get more respect for practical solution thinking! Keep up the good work!
Couldn't agree more!
Another CEE Friday, always love the hard work you both put in and the wealth of information you give us.
Glad you enjoy it!
i have seen only a couple of your videos . with many years building/repairing machinery,tooling,equipment and working with hundreds of men in doing so. a handfull of which i would trust to have the nessacary disipline , skill , patients , and attitude or spirit of service to not only do well but enjoy and then share with others . Rendering humble service with grattitude .qualitys needed to be sucessfull at any endevor i think . a lastly having a wife support you in your effort tops it!!
i loved the explanation of the hydraulic cyl orientation, only one minute in and started learning.
awesome glad to hear that!
If you ever take on a worker these videos will be an absolute asset. Such a good resource so they learn your work flow and thought process
I want to congratulate your camera operator/producer/video editor/production supervisor/animal wrangler for the new shots/editing on this one...also I chuckled at the reaction to the bearing insert dropping during the press.
As a long time fabricator and sometimes machinist, I've always been impresse with Kurtis' ability to do it all. Of course , Karen's expertise with videography makes it possible for me to see it. The Homie cam is a great addition!
yea feel like well made famly entertaiment my kids and me love them
Hello from England, just subbed, great work. I'm a 77 yr old mechanical fitter. At one time I was air arcing stainless steel brewing vessels. I ran a small engineering service business.
I found myself thinking a few times “I wonder if he misses that quick change tool post yet?” and then I watched the outtakes. You guys once again are nothing less than impressive.
watching those huge threads get cut is mesmerizing. incredible work, as always.
These are my favorite, used to do the exact same work. Miss it. I’m all CNC now. I especially loved replacing bushings and putting in grease grooves., also, thank you for the “thread pen” idea for checking the pitch without a scratch pass! I never thought of that. Would have saved me at least once on a critical part.
always the scariest part of any job...threads !!! or knurling. both were/are so temperemental. knurling does me every time... theres just no consistency.
Karen has to be one of the best videographers on UA-cam. Her sense of timing for when to cut to close ups or slow motion and back is just superb. Really love watching your videos for both the content and to see how Karen is going to film it. Also i take it that it is easier to get new chrome rods than it is to get old rods re-chromed? Will you be sending the old rod out for re-chroming?
And add to that time lapses that don't sound like mice squeaking, that's so nice to watch
He mentioned unreasonable delays in getting rods re-chromed during the intro.
@@russelldold4827 I just wondered if the re-chroming was also done by the same companies that would chrome the rods the first time.
@@jenksify I don't know the answer to your question. In this instance the original rod that was being replaced was a Hitachi product, and I suspect they are big enough to have an in-house division who make all their components, and I would guess they also offer a remanufacturing service (at a price, of course). The reason the customer brought this job to this shop was primarily based on turnaround time - re-chroming services would take too long and the risk of downtime from failure while waiting was high enough to justify the spare.
@@russelldold4827 Agreed. Just was curious about the routine. I have noticed that Kurtis doesn't seem to have as much problems with his distributor for his material.
Given the significant material cost and the fact that you now have time on your side, is it worth sending the old rod away for rechroming and putting it in the inventory for a future repair? I guess that probably depends on how many of those EX 1900 rods you are likely to do.
The world will stop without machinists, respect to all of you out there.
Another big project! I really like the split screen, multi angle shots. I'm sure they are a lot more work, so I just wanted to mention it.
Oh and of course the new Homey-cam is brilliant!
Thanks as always for sharing your adventures. 🙂
$10,000 worth of material lol. I was crapping myself machining up a £50 rod blank for one of my projects earlier this week. 😂😄🤣
Great content as always Kurtis, love the videography Karen, Homeycam is brilliant. I can’t wait for the next one.
Chump change. I have machined lumps of metal worth over 250K +
@@harezy Yea right.
Its certainly makes you pay attention and not frackup
@@chattonlad9382 Yes right. It was an oil exploration drilling head/assemby for one of the worlds largest oil exploration companies. Trust me even that's still cheap!. Aerospace/motorsports/oil expiration have some VERY expensive parts.
@@harezy yeah mess that up and u be gone that's for sure
I have to say this is one of my favorite channels after a long day of work. Your expertise as a team, between the machining and the filming and editing side, shows a true workmanship that is a dying trait in todays society. I can honestly say i look forward to every video you release and on many occasions go back and watch previous videos multiple times. The humor in your videos as well as the outtakes crack me up and just lets everyone know your real people. Homeless is another reason to come back every time a video drops. But, i have to say the biggest thing i appreciate about you and your channel is your ability to keep your private life and business life separate. i think to many people put to much of themselves out there on the web just to gain a few more subs, likes and views but is it worth it. I like the fact that you two keep your personal life off the camera and leave people guessing. Dont ever let anyone take that from you or convince you otherwise unless its your choice.
Mrs CEE’s editing skills are superb. She always does an incredible job of laying out a story with her videos. She has the vision of a documentary filmmaker.
Wow, thank you! Really appreciate such a great comment 🥰
@@CuttingEdgeEngineering glad that you saw my comment! I’m serious…yes, you work your ass off to put out these vids, but you definitely have a creative gift!
Friday Night, Dinner, Beer and CEE Video. Awesome :)
I'm not a machinist, but I really like watching how things are made. I enjoy seeing all the different tools, but I'm truly amazed by all amount of all the different materials, various liquids, sprays, straps, lubricants, welding materials, etc, that go into making things.
I like the editing on these too. They remind me of a film maker who said, "I cut out the boring parts." So things move forward at a good clip. Watching Homeless run around makes for a nice break every now and again. I wonder what your shooting ratio is.
But what does happen if you make a mistake on a piece of hardened material like that? Can you build it back up and use it for something less stressful? Or is it for the recycle bin at that point?
Also, to whoever sent in the cam harness for Homey: A heartfelt Thankyouthankyouthankyou from all of us!
Another great video on repairing big equipment. Nice to see this one followed on nicely from the brass jaws fix for this lathe in the last video. The split screen is a nice touch as well Karen, well done guys :)
being in the manual trades such as i am, (38 years trade experience) i just love to way you go about each job and the confidence you have in doing them......i sometimes need to remind myself that most of your jobs involve weights above 500kgs.....and after watching you rebuild/recreate i always look forward to the outtakes.....some absolute pearlers i might add......keep up the awesome machining mate
Funny how I hit rewind and pause when you showed the supporting end. I said to myself, that is an awful lot of weight on that little point as I was looking at that saying WOW! 😂 Then I hit play and you jumped right in with an explanation of how your machine can handle that. Good job Curtis 👍
hahaa yeah the good things about taking time to read & reply to comments, we get to know what viewers might be going to ask about 😂👍
The rod would've been ground using that centre, it's more than big enough.
I used to turn the steady bands on 5t billets with a No.4 centre, the old guy that run the machine before me used a centre punch divet, I was never that brave. The worst part of the job was shoveling 1.5t of swarf after making a 3.5t shaft from the 5t billet.
@@CuttingEdgeEngineering Been a faithful follower for a year and a half now. From San Diego Ca. USA.
The best start to a Friday morning in California is a new CEE video! Love your work, professionalism and attention to detail, Kurtis. Ditto, Karen's camera and editing work. You two are a GREAT team!
what part of California do you live in that 11:40 PM is morning time lol
You beat me to the punch over here in the French Riviera ... always great to have a new CEE vid to go with my Coffee ... any day of the week !!!
It's 3:17 pm in Chiang Mai right now, and I just enjoyed a delicious afternoon coffee, a scone and CEE's marvellous video 😁
It's so beautiful to see real master doing staff and make it look so easy while you have problem screwing shelf to the wall.
Every new video is better than the previous one!
For me in particular, it's like seeing my father back to life working in his old workshop. thank you very much and greetings from Brazil!
bloody love watching you make things like this, especially like the way you blend explaining what is actually going on followed with the speeded up bits that make it seem almost magical as all the machining appears with the level of accuracy you operate to, nothing better to watch while im eating breakfast!. Happy friday have a good weekend!
I do my single point screw cutting exactly the same way only as the screw threads are maybe 1" dia. I don't need to stand on the Lathe bed to try the nut! That was impressive!
Wonder if it is possible to "patch hard chrome plate" as in just replate those areas where it has come off? No good if it is cracked or starting to blister all over. Saves the cost of buying a new hard chrome plated rod and having to remove and reweld the eye end.
Other thing is maybe set up your own stripping and hard chrome plating line. Would need a BIG grinder to grind the hard chrome back to size and needless to say the chrome plating line would need a good effluent treatment system. Last one I had done yielded typically 0.5 ppm dissolved metals, about ten times better than the required standard. Dipped my finger in the effluent discharge to see if I could taste anything, but I couldn't. Plating shop guys thought I was nuts. Rod material I'd guess was SAE 4140, the classic "shafting" steel.
I am continually impressed by both the size and the quality of your work! Your channel is the most interesting of all the "restoration" channels on UA-cam! When it comes to My Mechanic's "I make a new one", you exceed even the Master!
Thank you! Cheers!
The blue tape to avoid the chips going in between the steady bearings and the shaft was brilliant, It`s awesome to see how other machinists go about doing things
ONE OF THE 1ST JOBS I HAD AFTER GRADUATING HIGH SCHOOL...WAS HOLTZ RUBBER COMPANY IN LODI CALIFORNIA...THE MADE SOLID RUBBER TIRES FOR FORK LIFTS & LINED BIG TANKS WITH RUBBER.. ALSO GASKETS AND O RINGS...I MET MR. HOLTZ...A WIREY GUY THAT MUST HAVE BEEN SOLID GERMAN...HE WAS KEWL!!!
I’ll bet the people who send these to you to repair think there’s a whole crew working on this to complete the job while it’s just you! One incredibly talented individual.
One thing that can’t be shown on the video is the pressure to not make a mistake cause if you get it wrong that $10k is on you not the customer.😱 Karen, your filming just keeps getting better, I like the angles you’re getting and the split view. Cheers, Stuart, Canberra.
Cheers mate!!
That crane is such a life savor, trying to leave room for the lift and jossling cr@p around would be horrible.
Having said that you could get a hydraulic cart and put a lift kit on it so you could make the height to the press or table for these smaller items as opposed to using the forklift.
Mr Curtis you are a such a great machinist your attention to the details are so much needed ever one needs to take pride in there jobs there name is everything. Great work. Congratulations to your wife her details are amazing with camera skills. She could get a job anywhere with here eyes for catching the right angle.
You and your Wife work so amazing together. Keep up the great work. Real Talk 101 !!!!!! Truth be told 100 !!!!!
Wow, thanks for the great comment mate!
How critical are concintricity tolerances on rods like these? I'm sure the material is round, but wouldn't the best 3-jaw still have some runout that far from the chuck? And when flipped the soft jaws might also cause some runout? Great work, way larger than anything I have turned
Always nice to get the notification on Friday morning. Have a good weekend guys!
Big thumbs up to Karen! I hope I have her name right. I am a video editor and I get that the work to do all those cuts is enormous. To get that done in a week is hard yakka. We'll done you!
Yes that's my name! And thank you so much for the compliment I appreciate it 😁
All that weight on that center is INCREDIBLY IMPRESSIVE!!!! Quality 💯
Fantastic photography Karen! The close ups. The split screens. The editing. You are getting soooo good at this! And of course Kurtis, your work is so fascinating to watch. Just a job for you. Entertainment for us! Thanks for sharing your lives with us folks stuck in the snow way up north (central Oregon, US).
Impressive as always. Curtis makes it seem so easy. I like the slow-mo with the sound the chips make as they fly off. I also like the long strands of cuttings. Fabulous editing, Karen. And, Homie-cam is awesome. I'm surprised by the steadiness of the video. Love your channel.
Two things that impress the hell out of me (besides the stellar machining skills):
1. Mad forklift skills - with the forklift at full throttle and a 1 ton chunk of iron on the forks, you barely clear the door by a banana... In reverse... Every time...
2. Mad balancing skills - It seems you get that sling at exactly the center of gravity first time every time, of every piece you pick up with the crane... HOW??? Or is it just the magic of cinematography?
One of my favorite UA-cam channels - Keep up the fair work, botayuz! 😍
Excellent machining Curtis! You guys are so good at what you do. It looks like you both really enjoy each other and your work. It doesn’t get much better than that!
Amazing work as usual. I hope at some point you take on apprentices to pass on the skills to the next generation of Aussie machinists. Thanks for sharing ♥️
uauu......parabens...que trabalho de classe.....pergunta ..A bucha de bronze vc que fez tambem ??
I am a surveyor that has set thousands of pipe. I worked in Canada and set cut off on vertical pipe (over 10,000 pipe) with 1mm of tolerance. I am truly impressed with your skills. So how long did it take you to go from Machinist helper to master machinist? You are the only you tube that I watch from begin g to end.
I love Karen's reaction to the press!
Every time! Keep it up guys, great job.
Excellent work. Love the clock in the background. Am always wondering how long various steps take. I can only imagine what that shaft cost. Always amazed when you cut the end off and stop exactly where its need to simply separate it gently with a bar. Tons of material and yet super fine precision on the lathe. Two hours of welding to re-attach the eye - wow.
The new rod was worth about AU$ 10,000 as he said in the end. Gives a little idea of how much the whole excavator costs !!!
Fascinating. The video work is bang on as is the explanation of proceess in machining. This young people is why you learn math, stay in school, learn a trade. It's folks like this that truly make a base line of modern life possible for the masses. They literally make the world go round.
I loved the "Homie Cam"! I was amazed at how steady the picture was even when Homeless was running. Is it stabilized?
gopro hero 10, has a great stabilization and it was on activity mode so stabilizer working overtime
@@CuttingEdgeEngineering I really like how you take the time to respond to comments. I love you guys, and your content never fails to keep me interested!
Yaaaah! Homey cam!!!! Love it, love watching Kurtiss do it to it...Mozart Machinist Extraordinaire for real, nothin' stops him!!! 💪😎 Cool vid watchin' that metal come off in slow mo, thanks Karen!
thanks for the great comment David we appreciate it
@@CuttingEdgeEngineering Just love you guys!!!!🥰
This brings back memories since I was a cnc lathe machinist making hydraulics components.Watching people turn metal on a manual lathe is alot more time consuming but still gets the job done.
Great start, and I loved the early mid week video.
Was that a 36.5mm spanner you used on the steady? I'm surprised you didn't break out in a rash.
Brilliant audio on the chips Karen.
Glad you enjoyed it!
Very cool, thank you for showing your skills once again. Always fascinating to see pieces this big handled. I appreciate you telling us the weight of the rod, it puts it into perspective. If you mentioned the size and weight of the jobs more often, I wouldn't complain. Cheers.
hey mate thanks for watching and sharing that feedback!
I enjoy watching the skill, accuracy, and patience you exhibit in these videos.
I know it takes much longer than the video shows.
As for me, I don't possess the patience for machining.
Good on ya mate!
I don’t think there’s any other UA-cam channel that gets this much (well deserved) love in the comments section. This channel is epic, I watch every vid. A true master of his craft and the cam/edit work is also great! Well done guys!! Keep it up. Hello from the UK 👍
Liking the blue duct tape 👍Was it chosen for price/performance reasons, or because it looks great on video?
Homey Cam footage was brilliant (GoPro should use it to demo the image stabilisation qualities of their cameras). Homey even gave us some outtakes 😂
Just wondering what the highest pucker factor moment was when machining a $10,000 length of chrome bar?
All the best,
Paul
there was no grey tape left 😂 The GoPro is on activity mode so stabilization is working overtime but it definitely works well! It's all pretty straight forward the highest pucker factor is the steady rollers...worrying about them either locking up or metal chip getting caught in there and damaging the material. At one point when I was rough machining Karen noticed part of the tape had melted away and I was quick enough to cover it up but that could have ended really badly 😅 Great question mate, have a good weekend
@@CuttingEdgeEngineering Here is an idea from an "armchair expert" 😂 - What about fitting air knives before each steady roller? They would blow any chips/debris away from the rollers before they could end up under the rollers. Does that make sense? (probably plenty of reasons that it does not 🤔 ).
Kurtis is definitely on my top 10 UA-camr go-team for the apocalypse.
Can we take a moment to applaud that this channel got over 250,000 people to take almost an hour out of their day to watch your video within 22 hrs of being posted ! Amazing haha great video 👍
Seriously awesome, we are very grateful for all the support of our viewers!
I would absolutely love to see the analytics of a video like this.
You've done a lot of great videos you two, but this is just about perfect!
Wow, thank you! 🥰
@@CuttingEdgeEngineering Really - everything flowed just right!
Love the dog. Such unbridled enthusiasm makes me feel good. Good luck on your endeavors!
Hey Kurtis, have you ever considered doing any type of teaching of some sort? You're very good at explaining what each piece does, what you're doing and why you're doing it, and you have a genuine talent and massive knowledge base, I wish my teachers in trade school were half as good as you are at what you do!
thanks for saying so mate, it takes a few goes for me to get the words right most of the time and haven't considered teaching I actually hated school myself 😂 hopefully the videos can help others learn or inspire to go out there and give something a go
@@CuttingEdgeEngineering You're probably right, I can't picture you in a classroom setting... Well, you could always take on an orphaned street urnchin as an apprentice. You did well teaching Homey, why not try training up a human?😉 Ok, kidding aside, what you COULD do is do some more tutorial-style educational videos. You'd have all the time in the world to get it right _and_ you would reach more people than in a classroom setting anyways.
karens videos help a lot too, she films exactly where we want to see
They say in Music and tech, those who can DO, those who can't TEACH. Kurtis is Doing.
Profissional valoroso.
Filmagem e edição muito bem feita. O vídeo não é cansativo.
Parabéns aos dois e ao dog também.😃
