Replace DAMAGED Circle Segments for CAT 12M Grader | Welding Fabrication
Вставка
- Опубліковано 20 вер 2024
- This video is a job we did to replace the damaged and worn out segments on a circle for a Caterpillar 12M Motor Grader. The grader missed it’s routine maintenance which resulted in quickly worn out circle segments. We need to cut out the worn segments then fit and weld in the new segments. First we mark out and cut out the worn segments using our oxy gas cutting torch. We then carefully measure and fit the new segments and use our 9” inch angle grinder to perfectly align and fit. We then tack weld before fulling welding out both sides of the new segments to the circle. We then grind back the welds using the 9” inch angle grinder before linishing to finish.
In this video we are using:
- Makita 2400W 9” inch Angle Grinder
- WIA Weldmatic 500i Welder

How many hours would this job take me? Give me weeks 🤣
12 hrs seems about right.
16 hrs for just the job, + 4 for video.
just a guess I would say 12 too 14 hrs to do that job ,,me it would take 2 weeks just to think about doing that job ,,i am still trying to think how to get in the center of the ring ,, i like how you had the jig too check your fit of the new segments ,, Homeless toy has held up .. my 2 dogs mix , boxer and husky with a bit of pit .. there brothers from the same litter ,, they destroy there toys ,tug of war with stuffed toys ,, when there done looks like a crime scene toy guts all over ,, thank you for taking the time to put a video out every week , love watching them , 6 days 23 hours till the next video .. ugh good thing i can re watch old videos
Best part of a day at least, guessing 8-10 hours once parts arrived
I never thought I would be able to complete this repair properly, but I would just like to say that after watching this video a few times I finished my first circle today. All measurements were bang on. Thank you CEE!!!
Hey mate just seen this comment, that is awesome glad the video helped 😎👊
yeah i am very impressed how hes got the techniques and knowledge of heavy machinery and always does a perfect job, he is truly dedicated to his craft
I cannot believe that I am actually sitting here for hours on end watching someone repairing heavy equipment, but I am. Excellent vids, keep up the good work.
thanks for watching!
I do the same thing. Just watching this guy gives me some confidence to get into household repairs. Great stuff.
going to just say this i have been cutting steal with fire for 15 years and that is some of the cleanest hand cutting i have seen. 👍
Really cool operation. Thanks for the video. I’m 51 and don’t ever recall getting teary eyed of a coat rack/ key chain holder. So many good people in the world.
Thanks for watching mate, yeah that was such a thoughtful and generous gift
You could give I C Weld a run for his money with the torch, good stuff Kurtis and Mrs. K
Thanks mate I dunno about that Isaac is legendary with his torch work 😎👊💥
#TorchNorris
@@CuttingEdgeEngineering I don't think any decent welder could knock the finish on that gear 👌👍
I've been watching you for over 6 months and have been blown away by how steady you are when you use your torch. I'm a millwright and would love to have someone as smooth as you are on my team.
@@CuttingEdgeEngineering he is, you also, but he is the f...king master with his torch, oh i get my sweater today, great! only i have to pay tax the same, fu..k basterds.
After about 43 years in the sawmill. Millwright and truck shop. It’s so nice just to kick back and watch someone else do the work. I enjoy the videos thanks.
9 thousand views and 225 comments in one hour....fantastic......we love you here in the States...cheers, Paul
Hey Paul! Yeah absolutely crazy we will keep the vids coming for our awesome viewers 😎👊💥
What I like about this guy is he always pays attention to detail and he takes pride in his work 🇬🇧👍👍👍👍
Caterpillar should design the ring as a separate piece that is indexable for maximum life and bolt-on replaceability.
But given its current design, your jig is the perfect solution. And your work is is top notch, no doubt.
No money in that though 😂👍
@@CuttingEdgeEngineering lol! Touché
Cheers
dear CEE, your hubby Curtis, is a DR. SURGEON, PHYSICIST, AND METAL WIZARD. I love your videos I'm always learning something new. I am truly always amazed. It is just me, Martin your big fan, from the USA, thank you very much.
Hi Martin thanks for watching we are glad you enjoy it :)
The respect you have for your job shows. No corners cut. Absolutely perfect prep and execution. A real pleasure to watch.
I always like the detailed intro/explanation Kurtis delivers. The introduction allows one to wrap ones head around the project.
I like how you show how the part your fixing is actually used and where on a machine it goes, gives context! Keep up the great videos!
Your freehand cutting is unreal, I've cut with oxy and acetylene torchs and cutting a line with no guides and not missing that line hardly at all is hard as hell. Love this channel.
Curtis, I have determined that you are an old world craftsman. I am continuously impressed by your wide knowledge and your sill. These two things keep me coming back to your channel. The relationship between you and your wife is just adds frosting to the cake. Her skill as a cinematographer and editor is impressive so it is easy to predict a long and prosperous UA-cam career, thank you guys very much!
Enjoying going back watching some of your old video's remembering some of the tips and tricks of machining my father and grandfather taught me.
In the after pan shot around 20:18 I can’t tell where the seams between segments are! Amazing work
Pseudo free-handing the Oxycutting had me all kinds of spooked. I could never have gotten such nice cuts. Experience and a steady hand definitely counts.
hey mate thanks for watching yeah I've had my fair share of practice
I could not possibly have done that that well by hand! Plasma cutter held in a circumscriber or I would have told the kuka robot to do it! Brilliantly steady hand sir!
@@andrewallen9993 I suck at cutting freehand as well, so I built a cnc plasma table. I can rip plywood with a cordless circular saw or cut drywall with a knife freehand down a chalkline and stay +/- 1/16" or a mm or so of the line, but don't ask me to draw or cut a nice line with a single pointed tool.
@@CGT80 I can beat your accuracy with a hand saw but would definitely not Match you with a hand held power tool 🙂
@@andrewallen9993 A hand tool gives you more time to be accurate and it depends on whether you want more accuracy or speed. You probably have a lot of practice with a hand saw just like I have a lot of practice with a cordless saw. My cuts are slow enough to be accurate but still get the job done quickly and when I don't need as much accuracy I will cut faster to get done. Once in a while I will use a straight edge, panel saw, or table saw, but I prefer to use fewer tools and spend less time....taking the easy way out, especially since most of my work is on job sites rather than in a shop.
It never ceases to amaze me. No matter how flogged out and rooted something is when it arrives, it always looks new when it leaves. Top job.
Hi, Mister Curtis! I love, how you Do your Job! Realy very good made! Give these Man a Peace of Metal or Steel and a Welding Maschine or a Boring Maschine or a Lathe or a Hone Maschine or a Grinding Maschine. Than you can see how a "Scrap-Thing" comes to a new live. These Men from downunder dont cry or tell somthing... They make it happens! (Sorry for my bad Bad English, Sir!) All best for you and your Wife, Family, Dog and your Company! The Aussie's can be happy, they have Mr. Curtis and his Craftmanship 😎
As a tradesman myself I appreciate being able to watch another tradesman with similar pride in his work, despite it being a mechanical trade. (Electrical Fitter)
My brother you are a Thanks for the nice work you are doing lm very proud of you l done that work years ago the same what are you doing very good work of you God bless you and your family lovies lots
The little fella really likes that ball, amazed It's still in one piece.
not going to last much longer I'd say
@@CuttingEdgeEngineering Might still be partly there by next Friday. BIL had a similar brindle, he gave him some old fabric belt motorcycle tyres, with the beads cut out, as chew toys. Those lasted around 6 months before he destroyed them.
It didn't come with a handy carrying handle so he made one. Problem solved.
...what a nice guy.I´m a skilled german, with the same tinking,56 years...one word and I´m sitting in the not yet forbidden plane to support...and dogs love me..smile...
Yet another great CEE video - Thank you.
Always great to see a truly skilled craftsman at work.
Also - Shout out to Karen - some nice video work & editing.
Thanks again.
Hey mate thanks for watching and supporting we both appreciate it
Your outtakes seem like they take a long time. Obviously it takes multiple times to get the right sentences out about what you will be doing. Thumbs Up for your amazing work and attention to detail. It shows...
Very impressive work my friend. I was especially impressed with the smooth cuts you made with the torch as you began the project. Looked damn near like you cut the teeth out with a band saw. Tremendous job and fascinating to watch. Skilled craftsmen always make even the most difficult projects look easy. Well done Kurtis...well done.
Hey Paul thanks mate glad you enjoyed this one. Cheers, Kurtis
The cutting torch looked small for the thickness of the metal. All in your technique and a very steady hand. Well done!👍
@@edwinhsingmaster9135 ive always preferred the smallest tightest torch flame i can get away with, more control usually
What you are doing here takes skill foresight and concentration, You are Doing well !
I got accepted into welding school recently and watching your videos has me excited to get into the field! Keep up the awesome work!
You will be happier there than you ever would be at college
Stick at it, the world will always need welders.
First thing I noticed was the issues with the tape measure. I'm a retired machinest from Indiana, USA. I've used a carpenters folding ruler for many years. Measuring inside dimensions is easier with one. Tape measures are good most of the time too. Really appreciate your content. Like you're 4 legend friend as well.
George from Indiana USA
Yes , I like a ruler for that type measurement. I work in metric and give the rulers out to people I train as a gift for attending the meeting.
my god this man's talent knows no bounds
watching in the middle of tropical storm elsa right now...pretty fun combination, a storm, good video and whisky
Like my uncle used to say, “look at that, like it was born there!”
Top job.
Even in Italy we say something like that!
"just like a bought one!"
i like the added attention to detail after the welding process, meets my expectations and youra of course
The advantages of a clean and dialed torch. Nice cutting.
Really appreciate the fact that the repairs you do allow for a good deal of craftsmanship to be displayed. This may be a lost skill in the future. Great work, both of you as always and Homeless just seals the deal!
Thanks for the content.
Thanks mate great comment
Most of the participants in the discussion cannot do such a job. Their skill is to give advice and discuss.
You have a firm hand and a lot of experience. You are the Master.
👍⭐⭐⭐⭐⭐👍
That's got to be some exacting work plus nerve racking. Alignment is everything I would guess from watching you set the job up. Thanks for the look.
Bonjour ,nous habitons dans l'Est de la France ,en Moselle exactement ,et nous sommes en admirations devant vos vidéos, vos travaux ,votre ambition ..etc... bravo à vous ,bonne continuation et merci !! 👏
Homeless Big Nutz loves his toys!
Great video as usual.
thank you!
He sure does and so spoilt from all his UA-cam fans!
I'm so addicted to your channel. The business you have built is fucking amazing. Your knowledge and ability to explain what you need to accomplish is dead on. Love the pup. Thanks for what you do.
I need a "don't send me dirty shit" coffee mug or something
Will add that to the merch ideas!
Plus 2 here !
Add me to the list please...
I'd guessing you'd better get your order in week's before Warren@ Western truck and tractor hears of them. Bad fire near him, say a prayer.
I'd order 2 too! In fact I'd order 2 that says "send me all of your dirt shit..... I need loads of dirty shit!"
Congrats on your format . You are original in having your loved dog as the co star . So is the humanizing commentary post vid with your lady as the camera person. Good Aussie with talent .
That seems remarkably straightforward for a repair of this type. Your skill is showing again, you made it look easy!
We do a couple of things hose rings a month at work . We have a gig we hook a track burner up to for making the cuts . Never seen it done by hand before. Thanks for videos !!
Glad I'm not the only one with a December calendar still hanging in my shop....
Well, it IS winter there.
Mines 2017 January
Nice to see you always wear appropriate protective equipment 🤟
Hello K&K, thank you for this awesome video. I’ve never seen this done before and I must say your cutting and welding skills are remarkable. The quality of workmanship you exhibit is outstanding. It’s such a shame more tradesmen apply themselves to their trade like you do. I do building maintenance and most of my jobs involve fixing other people’s stuff ups or rectifying quick cheap jobs that didn’t last. Keep the videos coming. 👍👍😀😀🇦🇺🇦🇺
I bey you adore watching your husband work
Y’all bring me so much joy
Dam..that’s some great torch work there Kurtis.
Thanks mate!
He does his best work in the dark !!
Spot on
Prime example of why it is a brilliant carrier choice.
No university debt.
Own your own business
Work according to your schedule
Interesting work
A craftsman.I bet this guy is happy, minimal debt, high wages.
Well done young man.
I enjoy watching you being thorough and precise with all of your measuring. Good job on explaining that it's an important part of doing the job correctly!
Hi, it's time to give you a big compliment. I look at every video of you with great pleasure. Am a retired engineer. Your work reminds me of my job, which I enjoyed and successfully did for 40 years. Many greetings from Essen, Germany also to the camerawoman.
Cool combination of precision, heavy duty cutting and welding.
Probably one of the most impressive things is the entire operation is just 2 people.
Kurtis should really look at getting an intern or apprentice then. Once one it at Kurtis’ level of experience and skill, they should look at passing it on to another so they don’t have to learn the hard way.
It lives and works in dirt, and you treat it like art. Sheee-it! It's always good to see the 'ripper shank' chomping away.
Awesome job Kurtis! Great camera work Karen, the slow motion and editing are spot on! The condition of your shop and equipment is remarkable, tell Karl he does a good job of tidying up the place!
Hey mate what a great comment we appreciate it!
Karl only shows up if there is beer.
When I was 30 I would have been able to knock that job out in a day. Well, I’m 63 now and if I attempted that now,, well let’s just say, it would be scrap. Great job!
That was some intense grinding. With all the angles you had to consider, not a simple job.
The only bit I didn't like the look of was at 8:02 when it looked like he put the grinder nut on upside down (for a cutting disc), or was it my imagination ?
I can almost smell the welding & the grinder!! Awesome Job Brother 🤟🏻
Incredible workmanship and attention to detail. What a slog to get those segments out. Really accurate oxy acetylene cutting 👍👍
Cheers Doug thanks for watching
Blowin out the flame.. Same thing everywhere 🙈 Greetings from a Glassblower from Germany 🔥
Great video as always. Amazed by all of the strange things people bring in the have repaired. You would think since this is a normal maintenance piece it would be designed with bolts that allow the customer to add and remove worn out pieces. Thanks as always!!!!
Bolts don't mean it can be easily unbolted. Plus, with the stress these things see, bolts are likely to break. (I've had to cut out numerous bolts. and there's several videos of Kurt having to as well.) Welded in is plenty strong, and easy enough to remove... back in the shop. (there are those that would do this out in the field/ditch/pit/whatever, but I wouldn't.)
Smiling my head off watching u enjoying yourself
Amazing job Kurtis. Amazing video Karen 👏👏👏👏
I do think Kurtis needs que cards for the Introduction lol 😆
I just woke up, damn it's gonna be a great day cos CEE uploaded a new video
Bring on the weekend have a good one mate
Another ripper project from this small but great team. Greetings from Tasmania, stay safe all. 👍🇦🇺🦘
I am always impressed with your skills. Goes to show that only hard work leads to mastery of a skill. Great stuff!
Hey mate thank you!
Kurtis, just wanted to say I have watched almost all your videos. Love your work ethic and knowledge.
Pretty kewl, Kurtis! I'd be concerned about making a diameter measurement and being one tooth off. I guess that's why you tack-tack-tack the segments before laying down the mother bead.
I don't know what is going on with You Tube as I went to put a thumbs up like I usually do I noticed the thumbs down was already done so I changed it, thing is this is the first time I have watched this video, so who put the thumbs down, I love watching Curtis doing his professional best on every job I have watched, I wonder if You Tube has done this on any other of the videos I haven't even watched yet, something to be aware of guys I will be counting how many time this happens when i watch the older videos I come across, this is number 1, I have my safety officer on duty sticker and I love it.
I like to guess how he’s going to accomplish the job before hand. Usually I am wrong and he always does it a better way.
Curtis is BOSS! At his trade I love watching 🤟🏻
I always have to comment about the video and editing you and your lovely lady produce for us. Just like the work that comes out of CEE, everything is TOP NOTCH ! Oh how I miss the smell of burning oils, grease and metals of the shop. They should can that and make it into aerosol spray for us old retired farts eh, LOL. Thanks for the memories my friends. Take care eh.
hey mate always great to read your uplifting comments, maybe that's an idea for our merch store "machine shop man spray" 😂👍
@@CuttingEdgeEngineering A nose spray or drops eh, LOL. There are worse things out there to poison ourselves with. After 50 years+ of welding and smoking small cigars my Dr. put me on a puffer. For the first month, every time I blew my nose there would be black flakes with shiny spots as large as a fingernail (the spots not the whole flake) I took them up to the university in the city. Turns out the little shiny things were carbide and fiberglass from our grinding stones and disks. The damage has been done and no reversal but at least it isn't asthma so really all I need the puffer for is before bed so I don't get wakened up in the middle of the night. Take care eh !
this man puts it right back in a circle
Niiice! I really was looking forward to this one! Coffee: check, CEE: check! Have a nice Weekend everybody!!
Always good to show something different we think. Enjoy mate ☕
Your torching skills are on point. Very impressive.
Loving your videos guys!! Always learn a ton of good information. The outtakes get me rollin every time!! Cheers 🍻
Great comment to read we'll keep the vids going with support like this 😎👍
Your welds are works of art. And the explanation of the job is the best I've heard in a while.
Give Homeless a "Good Dog," from Sneeker and me. Y'all are a great team. I truly enjoy the experience every week. Thank you 😊.
I was self employed for most of my working career, and I would always tell my customers how important routine maintenance was on their equipment. You can pay me a little to maintain it today, or a LOT later to fix or replace your equipment. Either way, you’re going to pay.
Right on mate!
That explains how I can use cars a half century old or more as daily drivers for forty years!
I enjoy to watch your videos your neat and precise work and the fact that you don’t take shortcuts to get the end result
Now I know what I'm watching while I "work" 😉
👏 working hard haha
@@CuttingEdgeEngineering I love hard work, I could watch it all day.
G’day Kurtis and Mrs K. One thing with earthmoving equipment everything is big including the welding jobs, well explained and first class. I enjoy your videos.
Cheers
Peter
Another great video guys I'm surprised how Karen manages to hold it together and not just burst out in hysterical laughter when you really do balls up on the bloopers .. and that train has got you quite a few times now lol ..
I guess as long as Caterpillar keep designing wearable parts you will always be on the receiving end for some good repairs and great videos . Cheers guys great end to me week .
Hey mate I think she is so used to my balls ups now it's usually she starts laughing before cause she knows it's coming haha. Yeah certain times of the day we get a train going passed every 15 minutes 😂
Best part of a California Friday morning is a new CEE video! Awesome work, Kurtis!
*I don't have as much confidence, making toast, as he does doing this.* I see so many parts of this rebuild that I could screw up, too much pressure.
Perfect job mate, lot of welding going on there.
Good dog training advice for the lady of the house:
Offer Homeless a treat in exchange for whatever he has in his mouth, comment with a light voice "good dog", it works almost every time. Treats are the way to a dogs attention, much easier to get in contact with him when he knows you have treats. Treats are better than his normal food, old dried meat in small pieces 1 cm cubes maximum.
Cheers

Machinist and fitter of the mercy of God :)
Great vid as always! Man you did a nice job with cutting away those teeth, super smooth!
Hey Paul cheers mate
Great work as always. Always great to see the star of the show the PUPPY hard at work. Take care
Fuck yeah. Sitting at home isolating awaiting a covid test. This is just what I need. Beer in hand. Thanks 👍
Damn that sucks yes Friday new video's make everything better 🤣
COVID? What county are you in?
Being OCD is horrible, can't see anything here to point at. I worked in a fabrication shop for a while, was the person our boss would call in to go over a job to find "things". Our specialty was stainless steel fume hoods which we shipped all over the world. They had to be as perfect as humanly possible with no indications of seam welding.
You sir would fit in very well, one of the fabricators I would pass without even looking.
Thanks Karen for your uplifting laugh,
Hey Donnie thanks for taking time to watch it mate glad you enjoyed it and appreciate the comment 😎👍
I’d guess that job takes you two work days, 3 with filming. Hours wise, that’s difficult to say. I see your videos with both you there early and really late, so I ain’t touching an hours guess. Still love the bloopers at the end 🤣
27 hours..... Nice repair as usual.... Great photography !!!!!
Outakes are so good at the end lol
Nice to see something besides the lathe work. Kurtis makes cutting with the torch look easy.
yeah good to have the variety
Possible dumb question:
Why is the ring gear not designed to be rotated and set back in place once one third of the gears are worn?
Any chance there are idler gears meshing at say 120 and 240 degrees to the driving gear? Just a guess.
good question and you'll have to ask the Caterpillar design team that one mate haha
@tacfoley Yes, to make the ring a separate part would involve each half of the section having to be as strong as the full ring, and you would need multiple clamping points to ensure that the inner ring is not going to distort. Would add easily an extra half ton of steel to the grader section, and would require the rest of the frame to b stronger, the attachments to be bigger, the frame sections there to be thicker, and the cylinders to be a size or so bigger. All in all would be probably an extra 2 tons mass, and you then run into constraints on wheel loading, and driver training and working ability.
Easier for CAT to simply laser cut the ring as a single unit, then weld the outer brace on to it, and then have the side sections welded on, making a much stronger unit that is relatively light in mass. There is a laser cutting operation near me that makes those parts for CAT amongst others, and they will try to minimise waste in the sheet, so there is going to be a few other parts, that need that thick steel, cut out of the inner section before the ring is cut. All about maximising the usage of each sheet, to cut input cost.
I thought that too. It would be a major job to disassemble the unit though and you probably only get 3 rotations before the whole ring would need to be replaced. So it would be cheaper (but not necessarily quicker) in the short term but more expensive in the long term since it cost time and labour to disassemble rotate and then reassemble each time.
Because that would mean less parts CAT would be able to sell.
That was a very big job and delicate to stick to the right specifications
Great tooth job! We will have to call him the Dentist!
🤣👍I'm a man of many trades haha
Another master class of a video. I stumbled on your channel by accident. Now I’m addicted👍👍👍👍
Welding upside-down is a trick and only professionals can make it look great
But as you see here it wasnt so great result and he turned whole piece around.
Other than the awkwardness (sometimes), it's actually a lot easier than vertical and a little easier than horizontal. This guy is definitely a professional though.
@@JJ79_ we didn't actually get a great look at the first pass on the bottom but it looked fine to me. And why shouldn't he flip it over? Only a fool would do something the hard way for no reason. Plus, it saves his back.
@@Lucas12v If you are really professional welder there is no need to turn anything. And sure the bottom look was good enough to see that welding wasnt so good.
@@JJ79_ so you would have hunched over and welded the bottom then spent an hour or more with a grinder right by your face while uncomfortable rather than flip the piece with the crane that you already have handy? You may or may not be a good welder but you're definitely not very practical.
