Restoring BIG Excavator Arm & Bucket! | PART 2 | Making & Installing Thrust Plates
Vložit
- čas přidán 11. 04. 2024
- We’re completing restoring the thrust faces of the big ZX690 Excavator stick and bucket! Part 1 was all about machining down the worn thrust faces with the WS2 Plus, now we’re tackling making and installing new thrust places. We start with flame cutting the high tensile steel to a rough profile, then it’s on to our lathe to machine the plates to exact dimensions. We can't forget about the O-ring, so we'll also machine a recess for it to sit securely. Next up are the replacement bushings for the bucket. We need to machine them to the right size before giving them a special cryogenic treatment - a fancy way of saying a dip in liquid nitrogen to ensure a snug fit when we install them in the bucket. ❄️ Finally, the moment of truth! We'll carefully fit and weld the new thrust plates onto the excavator attachment, giving it a new lease on life. This video showcases the meticulous work that goes into a successful repair. It's all about the details that get these machines back in action!
In this video we are using:
- Hafco TM-1740G Lathe
- Hafco TM-26120G Lathe
- WIA 500i Weldmatic welder

Hand burning, impressive work 👏
My weekly dose of CEE goodness… whoop whoop!! 🥳🥳🥳
Looking forward to more WS2 plus goodness
Turning ugly steel into nice steel.
Perfect work as always ,cant wait till a new larger job comes your way, i guess some people do not do what you do and thus shoot themselves in the foot ,where as you have your clients requirements at 100% and how can they save money and also make things last longer as well. 🦘🦘👌✌👍
Karen has such a brilliant sense of when to use slo-mo, normal, fast, time-lapse, and just skip to the end. These videos never get boring.
Thank you so much! I definitely put a lot of time into the editing to make the process visually engaging so your feedback is greatly appreciated 😄
Seconded. A real talent!
Don't forget brilliant direction. 👏
Karen is a true professional. Without her these videos wouldn’t be watchable.
@@CuttingEdgeEngineering the video quality is stunning along with the lights. Nice job.
“…that way the customer can do fixes themselves without needing me or my expensive kit…” - I paraphrase, but seriously, this is the mark of a great service - not angling for the customer tie-in but doing what is best for the client. So much respect!
Just before you added the coolant, you played some nice Oompah music on that versatile lathe - multi-skilled Kurtis, whistle while you work, etc. 😊
Karen, you make machining look so easy and fluid, great editing!
*- Agreed!*
I was going to say the same thing about Kurtis’ customer oriented approach as he was explaining how he’d make 4 bushes so the customer could do a quick swap when needed. That’s the sort of thing that’ll keep customers coming back.
Look up Wally’s working he also does the same
And that spin on 12:44 shows love of job :)
One of the main reasons he is unlikely to ever go out of business...
His Customers keep coming back and recommending him to their Industry Friends...
Hand cutting the Plates was the bit I respect the most from this shoot. Patience, Precision, Perseverance.
This judges awards 10/10.
Exactly - this is f...reaking impressive
Amazing torch work!
Really liked the pivot, brilliant !
most fabrication shops lilke colin furze, and grindhard plumbing have CNC cutting tables with plasma. I guess Kurtis is old school
Yeah that was really really impressive!
Hi, from Sweden. I worked in a shop with heavy duty machines and spare parts like this, once upon a time. I had two colleagues. One of them a pro-welder and the other one a latheprofessional. I learned a lot from these two guys. I never thought I would see guys like them or anything like this again in my life. Now I see both of them in one man, Kurtis! A true professional who works structured and precise. It's the same with Karen, very nice too see your way of working. Keep up the good work, both of you and say hello to your wonderful safety officer, Homey!
Hey mate thank you for the kind words we really appreciate that! And thanks for watching all the way in Sweden, glad you enjoy the videos 😄👍
32:07 what a stress 🥵!!
🤗 Its ok
I e done some chilled bearing fits. I was definitely not feeling chill when one got stuck. I got it out but the two seconds to find the prybar were like aeons of time.
I must say, it's really nice of all the large machine companies making replacement parts crazy spendy and keeping the independent machine shops in business!
Don't forget the multi-month lead times.
"PUCKER FACTOR" Absolute classic Kurtis.
I was right with you, damn, that was tense!
Do you do that on purpose? 😆
Yup, need a t-shirt or a cap with that. 🤣
11:24 - the machinist's waltz 😀
Seriously, the attention to editing detail (the rhythmic alignment of hitting the puncher), and business acumen towards customer operations and efficiency is what sets apart this channel from many others!
I heard that as well; it's something she obviously likes to do. But did you notice way she edited that final chamfering of the spacers?
@@timothyball3144 Very much so 🙂
Kurtis, I sincerely appreciate your effort to explain things, despite not liking it haha. That was some awesome torch skills - and of course the editing is always top notch!
*- Your customer gets a Huge Value for money spent, Kurtis!*
*- I would expect you will be flooded with more work in this direction.*
*- Great business plan, that is for sure.*
well just the fact the customer can see the workmanship he puts in ahead of time here goes a long way, just be honest and do good for your client, and you'll be beating them away and not spending a cent on advertising!
How did you make your sentences so small? Was it the - test test test
- test
-test
- seriously very curious
- test
- not working
Watching you mark amd measure that plate reminds me again of my father. He was a master of those operations, even with odd-shaped work.
The initial cut of the disks left liquid on the plate. Was that water from the combustion or a liquid petroleum residue?
You call that a washer? THIS is a washer!
Everything is bigger in Queensland!
Hahahaha nice
I can see at about the 10:00 mark when you mounted that first plate in the lathe using the hole that you just cut with a torch and when it spun up it looked almost perfectly round. Truly some skill on display there as usual!
Yup, I couldn’t believe how balls on he got those.
Man, I have to add "make a circle attachment for my torch kit" to my list of shop projects now. Always learning new stuff on your channel!
Yeah man, pretty cool & uncomplicated.
I agree. I've learned a lot from this channel, some I can use, some probably not. But, I am definitely gonna use the torch circle jig idea.
Those circles you cut by hand with the torch are super impressive!
He encompasses all skills.
czcams.com/video/tbcT02uVaGE/video.html Isaac from IC Weld cutting out a name. But he ain't no machinist
@@Gecko88I’ve cut a lot of stuff with Oxy in my day and even with an attachment I’ve never been able to cut 4 circles as clean and nice as that. Just about everything he does impresses me but since I’ve actually cut with oxy before this was cool to see, so laugh all you want.
@@Gecko88 I’m telling you! Dude barely had to turn them down!
what was also impressive was remembering to move the plate ( not that i've ever oxy-cut a fork lift fork .. honest boss )
Making big washers from scratch? Cutting bushes in half? Cleaning faces of big lumps of metal? No problem!
Taking the backing off of sticky tape? F*ck, f*ckety, f*ck-f*ck!
I have days like that too! :D
😂😂😂
Peeling the backing tape of that type of aluminium tape is a nightmare...
retired after 25 years as a Maint Tech at Snapper mower factory (McDonough GA, USA) i understand WELL the "pucker factor". GREAT job as always!!!!!!
One-man-two-hands CNC machine 😨The skill and precision with which Curtis cuts by blowtorch is unimaginable
super impressive how clean you cut with the gas axe
Impressive skills
Comments from all over the world are so fun to read. Excellent! 😊
What a cool but simple radius guide for the gas axe! - I bet every home workshop of every budding engineer all around the world will be making one - I know I will be!! Another top video in both content and delivery from K&K!!
Glad you liked it!
I'm amazed that with a hand cut piece the lathe tool made almost complete contact when touching off.
I had to hold my breath when you put the sleeves in and they sized, no pressure ehh! Brilliant looking job with plenty of explanation as to the logic of the repair and future maintenance, should make the customer very happy. Have a good weekend
Those freehand OXY skills are second to no one.
IC Weld can free hand like a boss!
@@CuttingEdgeEngineeringHe's scary good. Also the way he adjusts the mixture in a second. No black Acetylene soot flying in the air
Just Practice
Nothing was "Free Handed " he used a fixed pivot to turn a circle. Basically drawing a circle with a compass. Pretty standard procedure with a properly set up torch.🍻
@@Spitter-ud8jd Except it's not really fixed it just sits in the punchmark. Plenty of opportunity to fuck up that cut still.
In the UK in years gone bye we had a bloke called Fred Dibnah , absolute legend when it comes to old heavy engineering , he’d tackle pretty much anything in his back yard workshop . I think Fred would have been blown away by the range of skills Kurtis has , the documentaries on Fred were put together by professional production teams from the BBC , so kudos to Karen for doing such great work!
The complete Artistry of this channel is magnificent.
The filming
The editing
The freehand cutting
The musical lathe playing
The welding
The machining
The words of wisdom ie "pucker factor"
The forethought for clients
etc, etc, etc
Well done Kurtis, lovely Karen and of course, Homeless. Bravo.
Torch had a circle cutter on it but yes it was good
Thank you Karen for editing down the boring parts.
Saul Goodman:- "What boring parts?"
@@DogSerious Some of us don't need to see each degree of a fastener being turned, times 30 fasteners, in real time. As an example. Karen has a real knack for editing.
The boring was all done in the last video
@@chevbob 😂 👍
All I can say is thank goodness Karen's editing skills are exemplary , well done you two, another TRIUMPH 😊
😆 🤣 😂 was funny hearing the "bleep, bleep ..... BLEEP!!" for a change and I was a bit surprised but then thought 'yeah, guess that's a bit of abone shot deal so no cuts or second goes' but less in the way of bloopers lol
Thought you were going to have to bust out the ceramics on that corroded millscale there, only reason I know that is because of Keth Ruckers channel with him working on freshly casted cast iron parts and fresh steel materials etc.
Homie drives my beagle crazy! He hears him squeaking toys and then watches him play and goes nuts! 😂
Kurtis, your accuracy of the final clearance in such bulky components is outstanding for a manual machinist. There’s some good juju in that gold coast water. Oh, and by the way, where are all the flies - it’s Australia? Haven’t seen a fly in your workshop, ever 🧐
The birds keep them down, plus he is far away from a garbage dump and keeps the bins clean, so no flies. Bet there are a few red top fly catchers far downwind though, just for the stragglers.
I bet Curtis wishes his cutting torch had a turbo mode like it does in the videos in real life!
Karen the editing is super. Curtis the amount of attention you give to detail is awesome.
Lovely meticulous work. Love the outtakes.
I had a pucker with the bushes as well. 😮
That magpie has some serious speed on foot! He took that food and ran for it! 😂😂😂 Love the content!
His little run was too funny 😂 he's gotta be fast to get treats before George the greedy butcherbird! lol
I’m running out of superlatives! That was such an interesting project, and while Karen edited it beautifully, Kurtis looked beat from it. Be well and stay safe!
I always enjoy the little noises Karen makes. "oo!" "nice" "ahh".
Makes my chuckle, every time.
Kurtis just showed you why you don't needs a $100,000 CNC Machine when you can make cuts with a torch and some patience! Of course, it would be a nice to have! 😁😁
Again, just brilliant to see craftsmanship demonstrated, along with variety such as yoga and acrobatics required to cut the wear plates out, followed by magpie cardio… you want to shout you got wings, sport, you can fly… and they run like their knicker elastic is broken! Fantastic!
Well, just found one bright side to getting woken up at 2am (US Eastern time) by my blue heeler
Even your pooch wanted to see the latest video? Now that’s commitment, or maybe it’s just Sir Homeless.
Kurtis, I’ve watched way too many fabrication and machining videos in my life, and I’ve never seen a pivot point on a torch head before. You guys have all the cool toys 😉👍🏼🫡
Please give the safety officer an extra pig ear from his loyal fan base.
Karen, great videography as always, dear.
Cheers 🍻, from Ohio, USA 🇺🇸 🍌😜
That pivot looked shop made. Simple to use and easy to make.
as a "Semi beginner" machinist it makes me both proud and happy to see certain actions or quirks Kurtis has, such as slightly rotating the plate when its on the lathe chuck to make sure its flush against the chuck i do as well.
another one would be to use calipers to measure a turned part in multiple locations even though it should theoretically be the same for all measurements
You're getting quite good at this welding and machining malarkey, maybe you should consider taking it up as a trade. Thank you Karen and Kurtis, have a great weekend guys. WOOF! To Homie.
Kurtis. Your knowledge and ability astounds me. Anyone would think that you have been doing this job for a very long time. Stay safe folks, especially Homey.
CCE > Titans of CNC video content 😎
Wow, the circle cutting with the gas axe. When they got on the lathe, it was like they'd already been machined. One of the most impressive things I've ever seen you do, Kurtis. Thanks for another super entertaining project.
Somewhat funny how the cutting of those thrust wear rings gave me a slight feeling of cutting the branch you're sitting on, 😅 but also almost making a smiley emoticon halfway through cutting the inner diameter. 😄
That first facing sounded exactly like turning a brake rotor without the mass damper. Giving me flashbacks!
The damper is not just for noise, the vibrations get imprinted on the disc surface
@@erik_dk842 Didn't say it was, but noise is certainly the most _noticeable_ effect.
@@Azlehria Understandably. I would also hate to hear that noise day in and day out.
i wouldn’t be surprised if Kurtis could machine the brake rotors for the business truck if he had to
Kurtis, that plate cutting with the gas axe was magic, and you are the most skilled guy I have ever seen!
Hi Karen and Kurtis - thanks for the video; must say that was some awesome engineering and congratulations on the machining so that you had the required clearances at the end - truly amazing. Seeing you cutting out the thrust plates took me right back to the early 1960s when, as an apprentice, I used to get sent out into the yard with an oxy acetyline cutting torch to cut out plates of various diameters and out of steel sheets of varying thicknesses. The steel sheets used to be off loaded from the delivery lorry onto the ground so to separate them and get clearance for cutting was a tough job - no forklift or crane - just a crow bar and bricks!!! The plates were then machined to make moulds for producing rubber and silicone components for all sorts of engineering applications.
I have watched this channel for like 3-4 years now and learn something new every episode and for the first time ever I can offer you a tip haha! When machining the discs you can buy like clip on weight belt that you run on the outside edge of the rotor to stop the vibration or also get like these little tongs with brake pad material on them which are spring loaded and dampen the metal to reduce the chatter
It’s a common brake disc machining technique (that concludes my machining knowledge) absolutely love the channel tho keep up the great work
Weekend is here
Yay
TGIF Too bad I have my last shift of the week too night ahead of me.. Not an interesting role but our customers keep coming back.
Always fires me up for the last work day of he week!! :) thank you CEE Engineering!!
Love watching the machining work in things like this, so satisfying! On an editorial note, I'd just like to say that I appreciate how with repetitive sequences like this, Karen shows the first one at pretty much true speed and then a second one full through with the speed increased. I've found several times that I'll notice something at the end of the first pass that I want to see again, and about the time I think that, there it is without having to jump back in the video! Great anticipation and a sense for at least this audience member's interest. Thank you!
All that machining and exactly .5 mm clearance, astonishing! Such a pleasure to watch. 😲👍
Good morning Cutting Edge Engeneering Australia, greetings from Germany 🇩🇪.
Cant believe what a difference little changes make on the lathe
Adding selective out takes and the animal clips makes these videos enjoyable on so many levels. Thank you as always.
It is really satisfying when you run into a hiccup, and I think to myself what would I do in this situation, and then you do exactly what I came up with!
Great job, those thrust faces were a neat solution. The swarf wand is brilliant I bought one myself after seeing you use it previously, it beats the hell out of an old speaker magnet in a plastic bag for cleaning up!
How utterly enjoyable to watch the process ... good call on the thrust washer material !!! AND YOU EVEN PAINTED THE DIPPER ARM !!! Love it ~ if it "looks nice", an easier receiving inspection ... not kidding.
Super close ups and slow motion... another candidate for best video of the week, and I watch a big variety... Great work, and good to see the job out the door... including a spares kit!
From Encinitas CA 😎
The slow-mo at 24:30. Such a great shot. Great edit Karen 👌🏼
I'm here my Allen brother and sister (soon I hope). Hope you are both doing well. Great following this portion of your life. Hopefully one day we will be able to have a pint or a few together. Cheers to you both!
Thanks! We're doing great - glad you're enjoying the journey. 👍
I've never worked with high tensile plate, but we used high tensile bar stock for gearbox shafts. Surface finish used to be a challenge, but similar to you playing with speeds, feeds and tips sorted it out. Seeing Homey rip his Rubik cube up, our 165lb Pyrenean mountain dog has a little teddy bear around 75mm / 3" high. She takes it to bed with her and is, so far, unchewed. Great post, thanks. Keep safe and well 👍
Every Friday morning here in east Tennessee, I tune in to CEE with the expectation of being amazed. You NEVER disappoint. Incredible work made available to the rest of us with Karen's incredible videography and editing. Enjoy your weekend. You've both earned it..!!
My daughter just landed in Sydney and I think she plans on snapping a photo at your shop as a surprise gift to me. Love your content, thank you!
Good morning from Germany!
I'm always amazed by people who can cut with a torch like it is a fine scalpel. Eric O. from South Main Auto is another one like that. Cutting nuts off without damaging the threads from the bolt.
Go to IC Weld for unreal free hand cutting, but he's no machinist, save an occasional line boring using an old machine.
The Pakistan YT guys have great skill doing almost everything freehand, cleaner then I can do with a guide.
Can't believe Gorge ran all that way insted of flying 😄😄😄
Birds are intelligent enough to run if it wastes less energy than flying.
It's not George, he's a pied butcherbird and that was a magpie. Butcherbirds hop as in previous episodes.
One of the, if not the best fabricator/ machinist on CZcams. Thanks for the content. Always great.
Wow, thanks mate appreciate it!
No, thank you.@@CuttingEdgeEngineering
Amazed by the tight tolerances you have been able to work with…1mmm over more than half a meter (or 1/16” over 20 bananas…). You are a master!
Hey hey hey and welcome to the weekend!
Hey hey, it's Saturday?
What ever happened to Daryll and Ozzie?
Kurtis, after being used to you measuring with a micrometer, watching you marking with a chalk and cutting with a blowtorch _(exactly_ as the idiom says) is hilarious. I'm saying that as a compliment, because you KNOW when to use each of those things!
I was like „wonder how he‘ll cut circles with that torch? .. ohh, wow that’s clever 🙈“
Always admired hand to eye skills, top level on hand burning Kurtis, excellent repair with built in low cost option for customer.
Have a great weekend both
Cheers mate! Hope your weekend is a good one too 👍
Another masterpiece from down under, a great watch as always
Glad you enjoyed it!
Your skill level is phenomenal and your commitment to providing value for money for your clients is admirable. Clearly the two of you are a great team with a vision for the future. Your interaction with the local wildlife also reflects well on you both. Thank you both for sharing.
Just wanted to thank you guys for your amazing videos! My four year old woke up this morning in a night terror, and I couldn’t get him to calm down at all, so I pulled up your video and started watching. After about a minute of watching it over my should, he snuggled right up and asked me why you were making wheels 😂 we then watched for a good 15 minutes before he was calm enough to come out of his room with me and start the day much better. love the videos and love the quality of work. Keep it up!
Having operated a pattern cutting torch machine myself back in the day, after having watched you cut these washers out with a simple shopmade tool WOW!!!
Yes, definitely one for the "must remember that trick" file.
Aww, how good. Friday is just not the same without another CEE video episode and a look into the high quality work going on at your facility.
The endless techniques utilized are fascinating.
I'm kinda proud of myself. Because as soon as Kurtis measured from the torch tip to that pointy attachment it clicked in my brain and I went like "Damn, that is BRILLIANT!". I just had realized that Kurtis was about to cut circles with that torch. That's a pretty nifty trick! 😎🤟
Good morning from Texas Hill Country,. Back in the day ( I am 81 yrs.) I wish I had someone like you and your shop to do my repairs. Have a good day mate.
3am curtis is always the way to end my day
Quick tip on removing the backing on the aluminum tape. Bend a few millimeters of the end of the aluminum tape back over itself with the paper layer attached. The aluminum will stay bent, and the paper will try to straighten itself out, thus releasing the edge.
Loving the difference in language between injury (fiddlesticks 🥺) and messing up your lines (FFS!!! 🤬) 😂😂😂
Another Great CEE video. Always great to see Curtis making hard work look easy
Nothing like a smooth Bush !!
That circle cutting attachment is genius!
Pucker factor...shoud be entered into DIN/ANSI/BS/etc standards as a valid engineering term if not measure....ya gotta love it!
I could have sworn Kurtis was turning out plate steel smiling emojis
Having a machine shop myself, Kurtis makes these look too easy. I think people need to understand how much practice and experience it takes to oxy-cut a round shape like that with no automated machine! Great video, content, and editing as usual you guys!
Amazing how much heat that torch puts out to cut that metal like butter !
Open video, see Homeless having fun, click like
It has become a tradition to start my Friday mornings with coffee and CEE. Cheers from Austin, TX
2 huge, separate components machined to within 1mm of each other, kudos to Kurt's, as usual.
Its awesome how you don't just do the repair to be functional but instead go above and beyond to take the chance for an actual upgrade. I hope your customers watch your videos and appreciate all your effort to actually save them hazzle and money!
I'm always impressed anyway how you work on parts big enough to climb on and still do that crazy amount of precision at the same time.
Kurtis ,my name is Gerald Lewis. I live in Southwest Missouri in the U.S. I love watching your videos. I am a retired heavy equipment operator. I just wanted to say that when you sand the rust off of those big plates please wear a dust mask to help keep from breathing the dust into your lungs. I worked for years without breathing protection and now I have pulmonary phybrosis in my lungs. There is no cure for it and I have to have oxygen now twenty four seven.I am disabled because of it. So Senbe careful.
😳
Surprised at how much water the steel can hold😮
There is a bit of moisture in it but also Kurtis is using LPG (propane) combined with oxygen which produces water vapor
@CuttingEdgeEngineering I didn't know that thanks it's good to learn something new everyday
The clue is in the term Hydrocarbon!
@@CuttingEdgeEngineering thank you for explanation.
Always amazing to see precisely machined surfaces on a big old, clunky casting...
that torch circle maker is the bees knees when it comes to that! nice!
I was worried it was Thursday but then this arrived.. 😅 been that kinda week
I heard Benny Hill!!
Also I looked directly into the welding light, know what?
Keep the videos coming, I love them! Looks like you do top notch work!
