Repair Bail Arm BROKEN Into 3 Pieces | Part 1 | CAT 637 Scraper
This earthmoving part is completely broken into 3 pieces and we’re going to fix it! This is a Bail Arm off a twin drive push-pull Caterpillar 637 Scraper. The bail arm is used to hook up one scraper to another one in front of it so they can assist each other with taking big cuts. This bail arm has a lot of damage, both ends have broken off and one of the ends is bent. In this Part 1 video we show the step by step process of disassembling all the parts using an air arc gouger and grinding to prep them ready for assembly. We also use our 150 tonne hydraulic press to straighten the bent end before machining new pieces of hollow bar that will replace the broken sections of the bail arm.

In this video we are using:
- Lincoln Electric DC-400 welder
- Hafco HMP-150T Hydraulic press
- Hafco TM-26120G Centre Lathe

Righto so this part is almost FUBAR 😂and definitely one of the worse one's we have seen! P.S. Sorry about the wind & audio when we are outside 😩 *Watch next * Part 2 here: kzhead.info/sun/bNGvp7Wrbqull2g/bejne.html 😎👍 Follow us online here 👇🤳 TikTok: vt.tiktok.com/ZSdax3gNQ/ Instagram: instagram.com/cutting_edge_engineering Facebook: facebook.com/cuttingedgeengineeringaustralia/ Official CEE Merch shop: www.ceeshop.com.au
Kurtis we know what FUBAR means
3 pieces generally indicates FUBAR. 🤣
Why don't you experiment with some voiceover instead of direct narration? It can be interesting and can save you some time on "the train moments" 😁
@@demonknight7965 yes, 3 pieces as well as the trashed prior work evidence. Really adds another level to FUBAR.
R.I.P Workbench
I reckon the guy at the steel supplier has a grand sense of humour, knowing this was for CEE he wrapped the end of the 140x80 hollow bar stock with "Fragile" warning tape LOL
Spotted that too. Must have been to warn anything about to come in contact that it was more fragile than what was coming at them ;-)
@@TheEvertw more like a warning, "don't drop on toes"!.
Nah, he just grabbed the first roll of tape he found laying around. And as there's hardly anything fragile in that supplier's shop the tape is probably some cheap-sourced one from some surplus sale or stock sell-off of some company that went belly up. A tape is a tape, and if it sells for a third of the regular price it could have "biohazard" printed on it and no one would care ;-)
Yeah, I had to laugh when I saw that "Fragile" tape. What could be less fragile than this?
hey, it's hollow-bar, right? That's much more fragile than solid bar, no? ;) Like, it's just a relative thing? :D I dunno, just a guess. It amused me too. :)
My Man cut up his own table in order to get the job DONE on a weekend !!!! This is why I subscribed back when you only had 5K subscribers...............You do what you have to do to get the job done. Keep up the great work.
I don't weld, I don't do machine work, but I find these videos strangely addictive. I appreciate your skill and knowledge. I also love the back story about how you got to where you are.
I’d like to here more too
@@pennyoflaherty1345 If you watch the first Q / A video I think that is where the story is found!
Dude. Same. I can't stop watching.
I love seeing someone who is excellent in their field of expertise! Glad there is a backstory.
It's a real pleasure to watch someone who refuses to cut corners
Another sign of a true quality tradesman someone who can read the signs of the job at hand. I found it was something that most quality tradesmen were able to do and in the process, be able to do repairs or fix the problem with a certain amount of guarantee it won't break again My hat is again off to you my man. I get tingles watching quality being performed in the society of disposable throw away culture. All the best you you, Karen and homey. Cheers Ian
Hey Ian thanks for saying so mate, I agree it's getting harder to find "good work" that people take pride in. Having my name on the line is one good motivator
@@CuttingEdgeEngineering fantastic response and mad props for a ‘Job Well Done!’ Looking forward to your next video!
Hat off?? More like kissing the ground he walks on whilst throwing flower petals 🤣 I stand (ok....sit) in awe of your skill and professionalism. I will turn up on your doorstep one day to see it all first hand 👌
@@harryhino2267 I don't know if you're being facetious or not. I don't kiss the ground anyone walls on. I Have worked of close to fifty years and brought up and started working in the 70s working with a true work ethic. Not to mention being allowed to put quality above profit. Today it's, get it done as fast as you can and quality be damned. My grandfather always said, if a job is worth doing, it worth doing property. I appreciate the effort other put into there work and Kurtis has shown time and again he respects his reputation.
definately. sadly most diy guys like me dont exist much nowadays. 19k for a replacement. makes no sense
These arms are a real balance act between tough enough to take it, and not tough enough to transfer the damage to the machine. Whomever mathed them out, really knew what they were doing.
As a retired engineer I agree. The hollow tubes are effectively the fuse in the assembly.
I agree completely. I think it also serves another couple of purposes though. It gives it enough flex to not break in normal usage but still bend/break when the guy ballses it up and crashes it in the wrong position. I think it also helps in actually making it. If the loop was solid bar to the pivots it would be a right pain to get set up nicely for welding together. I reckon it's a long learned design rather than someone actually doing stress analysis stuff. Awesome thing😎
Enginerds almost earn their keep sometimes!
Anyone can design a bridge that stands forever. Only an engineer can build a bridge that barely stands.
There was a little bit of mathing it out amd a whole lot of trial and error What cat do well is reaserah their failures they dont just fob off their customers They might charge a fortune but they'll be studying what and how you broke whatever you bring to them
I like the way your forensic post mortem examinations of failed parts. Also you pull no punches calling out shit work. Good stuff. I hope the jackleg who did that work sees this.
Curtis, I’m an electrical engineer who studied at a university (Colorado State, a good one). And it is appropriate for me to say that you have a gift that no degree can offer. You are a natural, and you don’t say NO to the tough jobs. I love to watch you work mate, and wish you all the best. Same to your wife/GF and your terrier.
Yes it's a real fine skill. It's great to know the theory and I went to school for that also. That education prepared me for the 25 year journey that I continue to learn to this very day. Experience and common sense is what makes one highly efficient and not lose quality. There really is no short cuts to get good. Just get up at 4am everyday and work till the sun goes down....... After 25 years anyone will be good if they love what they do.
Well I've said it before and I'll say it again, Kurtis your knowledge and workmanship is off the charts and Karen's video work and editing is i think the best on KZhead. 👌
Thanks very much we both appreciate it!
“…needed some 20 mil plate, and I had a 20 mil workbench…” Gotta do what you gotta do sometimes! 👍
That workbench was a lifesaver 🤣👍
@@CuttingEdgeEngineering LOL..... Yep....It's gone ti it's next life. 😊
I laughed so hard at this line
It is called *"REAPPROPRIATION"* or robbing off Peter to pay Paul.... But I prefer Reappropriation, it sounds more professional! 😂🤣😂
@@joseywales3789 I use "Repurposing"! Looks at broken part. Hmmm. What have I got laying around I can make a new one out of? ;)
The price of the new part doesn’t matter if the part isn’t available for months. I bet there are plenty of jobs where Curtis could charge as much as the new unavailable part and his customers would gladly pay because equipment being down costs a lot of money.
Getting it done 1-2 days versus months. Definitely
This, also taking into account that his repairs usually are OEM or better from a quality standpoint.
@@HJZ75driver ..."TIME IS MONEY-!!!"
Yeah, even of his part lasted for 3 months before you could replace it. It would be cheaper than machine down. However his parts are gonna lasta rather long time.
@@daleburrell6273 Get it back in the dirt because time out of service also costs a lot of money, both for the machine value and the contract time.
Dieser Mann hat keine Probleme,nur Lösungen!!😁👍 Viele Grüße aus Deutschland!
I think this channel gains by the fact that both of you takes pride in your work.
Also the puppy
You always know a common repair when you have a jig tables already setup for the part, Another great Video.
Your dog is excited 24hrs a day, which shows just how happy he is! Great engineers, great dog owners therefore GREAT PEOPLE!!!
Once again I have to say that I'm impressed with the audio editing. A lot of work going in to having the correct audio even in the sped up video/slowmo. Well done, Karen! Top class! 👌
My thoughts, too!!
Karen is a PRO ! I agree !
There's an art to it that Karen has a handle on for sure.
Great editing--keeps getting better all the time, and Homey's "car ride" to the vet was great👍 Always fascinating to watch how Kurtis works and explains the steps he takes as he goes. 👍 Definitely looking forward to part two. 👍
Glad you enjoyed it
As a course of normal life, I drive by my vet. He only does the freakout once I turn in. Easier on both of us
I know right, just at the point my mind went, ‘why is he striking the end of the tube first’ he then explains why 😂
Between CEE and IC Weld, you both make your jobs look easy. I know it much more complicated than you show, but I feel like I can weld and turn anything after watching you all.
same, with this clear explanation and the description for safe handling. You could really use the vids as educational material
@@kobold2376 Several TAFE Colleges in Australia have approached CEE to be able to do just that. These videos are an excellent means of teaching correct habits and safe work practices in a way in which a person would be trained without realising it.
I knew you were gonna like the shade! It's SO much nicer working in the breeze, than in a shop. "Someone grabbed a bird that shit wire!" Classic! That was a substandard repair that came back to haunt the original "repairman", I'm thinking...
Why have I just spent 3 hours watching your vid's. I have nothing to do with engineering, but your vids are SO interesting they are addictive I can't help but watch more. At the start of each vid' I think "How the heck are you going to fix that". By the end of the vid' it is fixed good as new, all professionally done.
This was a really impressive fix Kurtis, the air arc gouging cut through it like butter! You are precise, efficient and thorough on every job you do and these videos are such a good advertisement for the calibre of work you punch out in your shop! Well done Karen for capturing it and editing it so well, what a team! Ps I am glad Homie is going well!
Glad you enjoyed it mate we appreciate the great comment!
Well, I had to watch this alone this morning as Karin and Halgrim are out and I just couldn't wait. Great diagnosis on the faulty repairs that had been made, followed by excellent corrective surgery. Thanks to you both!
Good morning Bruce you are very early to watch this weeks video! Hope you enjoy the rest of your Friday 😁👍
I watch alot of tradesmen videos of all sorts. I think yours is the only channel that don't have so called experts coming on critiquing your work.
Kurtis, And Your LIL woman appreciate the welding lens over the camera to see in depth how you prep and repair, APPRECIATE IT!!!
“A bird that shits wire” Fantastic and I think we have all seen welding like that in the past 😀😀 Great content again Kurtis and your usual brilliant camera work Karen I’m looking forward to seeing part 2 and the finished product. Homey reminds me so much of my 2 Staffie’s with the same mannerisms etc. My vet is very good with them and they actually like going to see her even when they get there booster injections etc. Your channel is top of my repair and engineering KZhead videos that I watch and it’s a real treat on a Friday morning here in the UK when I get to watch it 👍🏻👍🏻
Kurtis, you are a man for all seasons. The pride of a true engineer who has masterful skills and above. Your customers are very lucky to have your knowledge and expertise.
wow thanks mate
I had never heard of gouging rods before I started watching this channel, but Kurtis makes it look like an absolute art form. The surface it leaves is just beautiful.
Not gunna lie .... I skipped to the "Bloopers" and Homeless.... Then went back and watched the normal stuff. Sadly I have grown accustomed to the phenomenal work ethic, Attention to detail, and Master Level craftsmanship. Hooroo mate! =)
hahaa we love that viewers skip to the good parts 😂
As a comment to your explanation at the start: Excellent diagnosis, you do your job expertly. I trust your diagnosis 100%.
cheers mate!
A cliffhanger, how brutal! Liked the extra technical explanations in this one.
I don’t know anything about this line of work, none the less I love these videos
That gouging technique is amazing. Never heard of it before. As always, I learn something each time I watch your channel. I don't even work with metal outside of minor hobby stuff, but I find how it applies to what I am doing. I wish I had gone into working with metal instead of computers. My uncle was an artist at metal working, but he used his skills to make motorcycles, trucks, and of course worked full-time as a welder most of his life. I find I feel working with metal to be very calming and natural.
I've known of this most of my life, but never done it, been working on motorcycles and trucks, cars fifty years, just now getting to know what this actually looks like in action. Watching this is like finishing my degree in metalwork at retirement age. Your comment struck home for me too.
I couldn’t workout how you were going to get the measurements right …until I saw the jig ….guess you’ve done this many times before 👏🏻👏🏻
It was good that when I was ready to ask a question you gave the explanation before I had to ask. Striking the arc on the bare metal. And don't complain about the weather too much, it was 113F here today, you can put on more clothes but I'm too old and fat to take any more off! Great video, cool shots, and lots of information. Thanks, jack, in The Valley of the Sun, Arizona, USA
Hey mate yeah we have bloody nice weather here, 6°C is about as cold as it gets and summer isn't usually too hot just really humid
Your encyclopaedic knowledge can surely only mean you had one hell of a teacher.
You would think so, but he's actually self taught. I think he has a Q&A video that mentions it
wow@@laughkick
It is crazy how specialized you are. I have never ever seen this vehicle in my life, but you have special rig to repair one special part of these vehicles.
Another great lesson Kurtis, really enjoy how you analyze a piece's prior history of repairs👍
Another great video by CEE and Homie. He is always a treat. Thanks, Karen, for taking us along to the vet with you and Homie.
Dude you are a machinist-dentist! Killer stuff man!
My favorite part of the end of my week is the Friday video from CEE. Love watching you work. Thanks also to your wife for all the work with videography and editing. The bloopers always make my day.
Some damn good control with that Air-Arc cutting things down, can tell you've taken it around the block a few times.
yeah once or twice 😂👍
I dunno mate; I think you should try a classical violin; you'd probably embarrass a load of violin players. You're a master with that thing!
@@michaelrice500 Don't think a classical violin is much cop for removing metal mate🤣
@@luviskol Get it hot enough and blow O2 through it . . .
Excellent work, you can see that a real professional is working on it. The camera work is also excellent. Thank you for these impressive pictures. Many greetings from Germany.
I spit out my coffee when you rolled up with the work bench 🤣🤣 I recognized EXACTLY what had happened (for some reason)
I just want to say thanks for your videos. I’ve heard you say that you hate making them but I appreciate watching someone who obviously knows what they’re doing.
thanks for watching mate, it's great to know the videos are enjoyed
Just like a brand new part. You are wonderfully accomplished and brilliant. In so many different mediums. My Dad was a Tool and Die Maker who never had to farm out anything. He was 19 when WW ll broke out and he gained a lot of his confidence and skills during that tumultuous time. You are extremely Blessed and Gifted! I savor your TUBES. Like hanging out with my Dad in his tool room.
Cutting out the piece from table is the manliest thing I've heard of lately 😀
Always so fascinated by your approach to the diagnosis, repair process, and how you strive to to achieve or exceed OEM quality. Another great one!
Love the break down of why the component failed and previous repair inferior. The customer will be very happy with your expert repair and happy with the savings in the hip pocket $ Cheers
Awesome workbench! I truly did laugh out loud as it was flapping away on the forkie.
LOL one of a kind that
@@CuttingEdgeEngineering stage 1 weight reduction on the bench?!
Once again the camera and editing skills are up there with the Engineering Skills, 10/10 to both of you
Poor Homeless, nobody likes sitting in the Dr's office waiting! My wife and I think he is the best dog! The quality of work that is done at CEE far surpasses anything I can find in Michigan. Absolutely amazing!!
Have you watched Davin Haggety Redline Rebuilds channel in Travers City, MI.? He and his camera man produce some amazing engine rebuilding projects.
Loved the fragile tape on the stock. Looking forward to bringing my bits in soon for you to fix. Mckinnon Builders, Uki.
Same though with the fragile tape😅
It could make your flesh fragile 😂😂
The Fragile word is a reminder for the handler's toes.
Hey, couriers will bend it in half anyway, sticker or not. Though I would probably have put a "fork lift only" sticker and a pallet with it tied to it, else they will use it, as it looks like, as a roller.
nicely done Kurtis.... it must be very satisfying to clean up after that "bird that shits wire"... (that was hilarious) looking forward to part 2! And karen..... your editing skills are getting amazing! well done!!
10/10 operation on the hydraulic press by operator Giggles. Saved the bearing. 👍🏻...
Ich schaue aus Deutschland zu und bin begeistert von deiner Arbeit. Ein paar Sachen kann man sich abschauen für sich selbst. Mache weiter so.
What a great way to start the morning, a new CEE video. Fantastic work Kurtis. All the best from here in Belfast, N.Ireland mid summer.... well we only know it's summer because the rain is warm !
morning to you mate, awesome to know we have viewers all the way over there!
That's the beauty of fixing these things. Send it back to the owner, " You haven't broke what I can't fix"
That would make a great saying on a T-shirt! Something to think about! :)
Nice to see you"re wearing your cap in proper IC Weld fashion
Nice filter work on the camera so we can see that cut 4:58👍🏻 Our canine friend has loyalty born of love😊 Brilliant use of that table for position🥇loving the reverse auto traverse let off for marking high spots👌🏻
Wow, another Friday at trade school! Even though I'm retired and will never need what you teach us in reality, It neat to know how you do what you do. Thanks for the patience and education! I'm glad Homie is good to go! And, last but not least, thanks Karen for making Curtis look good and keep him on his marks :)
I love that you already had the welding jig for these bail arms. I wonder how many of these you rebuilt before building that jig
Beauty. Everyone clears the shop when air gouging.
Two parts ..ow my your learning lol 😆 😂 just no need mate .. could watch you all day bud ... Peace n love from Cumbria UK 🇬🇧 ❤️
Gday Kurtis and Karen, the previous repair certainly didn’t do the job but it’ll leave this workshop done properly, the cost of components and availability isn’t going to get better anytime soon, good to see Homey got a clear bill of health, awesome job as always, have a great weekend, cheers
yeah that previous repair was like a gift that kept on giving 😅 about to watch your new video mate! 😎👍
That was interesting. Not sure about the fragile bar, nor the special workbench, but the rest was pretty cool. I love how you have the jigs for all these weird jobs. Every Friday night I nearly forget. I turn off the work stuff, flip on the PC and OH! That's right - it's Friday! Karen's new video! yay! :-) Thanks heaps.
Which one of you knew that people would be so interested in watching you work all day on KZhead? They were correct.
I love that you cut your table up to get a job done ! You do what you gotta do. Love it !
Their are not words to properly describe your talent knowledge and workmanship! I'm always amazed how you take on these large projects!
I like the editing dept. As always nice work keeping things in order and moving along with well timed cuts! Thanks for all the work in that area that often, and by design, goes un noticed. Love the channel!
Quick suggestion for the editing department. If his voice distorts from a bad recording, just go with it. dub over Darth Vaders voice. 😆 🤣 😂
Homey is EXACTLY like every little kid ever! "ByeBye in da CarCar? Heck YEAH!" I love that dude!
I love the explanations, way more interesting than just a generic repair video with a 15 second audio looping over and over for 30 minutes 👍
Quite a noticeable difference in wall thickness between the scrap tubes and the proper repair. Always worth doing it properly!
Ok...this comment goes to Karen specifically...seriously woman you are getting really good at this video thing! The split screen and pic in pic...awesome, you're learning and taking your craft to the next level! I wish you nothing but continued success cause you got a talent here!
I love that this happens often enough that you have a jig for it!
15:34 that split screens hot was really awesome!! Keep up the great work mate:)))
Gooood morning from central Florida! Hope everyone has a great day!
hey mate what time is it there? Must be real early or late.
@@CuttingEdgeEngineering It is 3:10am EST
Really impressed with the way you use your equipment. I worked with light steel in mid sixties and don’t remember when cutting disks and pads came in. Guess the old guys did a lot of filing..... modern layered pad disks and cutting disks are incredible when seeing what you do with them...Thankyou for bringing us along with you.....Capalaba
that jig you used is awsome! obviously this aint the first time you’ve repaired one of these monsters.
And congratulations Kurtis, Karen, and Homey on cracking past 400,000 subscribers!
Those things take the entire mass of the vehicle and its energy of momentum . It's no wonder it broke with such thinner and cheaper material . But as always you repaired it masterfully. And cannibalizing the workbench was genius and hilarious at the same time! 😍😜
Its Friday evening, finished for the week and my favourite show is on...
sounds good mate, enjoy the weekend 😎👍
I always liked to Arc Gouge. Very calming and therapeutic. Love the videos keep up the good work !! And hello from the west coast USA.
I enjoy gouging, not so fun in summer but should be good with the container shelter setup now
@@CuttingEdgeEngineering It will be interesting seeing the next workshop update and seeing how you did all that.
Safety man is looking in great shape. Love them vets
The definition of..."Dirty hands, Clean money" / Blue collar bastard...I am addicted!
I can picture the engineer that designed that part of the machine thinking "I going to make it unbreakable" and the operator thinking"hold my beer while I fix that"🤭🤣😂
Things will always find a way to break . The best thing is to give it place to break that is not hidden and easy to get at. Production quotas are always set at +20% of machines capacity and then if a mechanic sees the breakage starting and reports it the usual response is "Do you know how much it's gonna cost to fix that?"
Air arc was my go to for weld removal too Kurtis. I also had so much more control and I think it's a lot cleaner. Another great video.
Right on mate 😎👊
13:50 SPARKNADO!! LOL So awesome to see you work your magic with the knowledge that you have to manage and treat those huge chucks of steel. Kay; back to the vid!
Thank you Kurtis Giggler and Homeless. I wish there were more men in the world that would sacrifice their work bench to get the job done. Wow.
With the quality of work put out u have to be the go to man in Australia another fantastic repair
The forensics of the damage is fascinating.
Loved the vet visit. Homeless is such a good safety dog!
What am I supposed to comment on anymore? The 2 things I was going to ask about Kurtis cleared up immediately. Well as always amazing work by both of you
Absolutely love the quality of work you do! It amazes me the skills and work ethics that you possess. As always great video and cannot wait for part 2 ……
The intro segments just keep getting better! You are the setting the bar high on machining video production!
24:00 That bit of Homey backing up from the door cracked me up, clearly he has prior experience at the Vets.... 😂
I'm 63 and I've been building and fabricating things all of my life. I'm currently a process engineer in the battery department for an EV manufacturing company. LOVE your channel ! ! ! !
Better than factory. Thanks for sharing . I’ve had to repair a few of those back in the day but the were 657E MODELS . Nice jig to work off . We didn’t get that luxury out in the field . Lol
Nice work guys - Karen - you are really nailing it with the camera work - excellent - makes it so much easier to watch/enjoy! (Hardly noticed the FUBAR)
Thanks so much!
Kurtis-The depth of your knowledge is absolutely stunning! I doubt there is anything you don't know or can't fix in the world of heavy metal and manual machining.
