Repair Bail Arm BROKEN Into 3 Pieces | Part 2 | CAT 637 Scraper
Вставка
- Опубліковано 6 вер 2024
- This is Part 2 of repairing an earthmoving part that is completely broken into 3 pieces! 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 2 video we complete the repair and show the step by step process of reassembling and welding the hollow bars, sleeves and stop plates to the bail arm. We also use our Sir Meccanica WS2 line boring machine to repair the bushing position. The repair is completed by griding down the welds and painting the entire bail arm with primer and CAT yellow paint.

Wow you know when it gets serious when Kurtis gets the tin of paint out 🤣😂🤣😂🤣😂🤣
Sorry, not up to Cat standards, no fisheyes or runs in the paint, no welds with bumps and ripples, and aligned correctly, so definitely not the standard CAT gets from the OEM shops who make for them.
Was thinking that 8mm drill bit with half metre extension bar would be a shop made tool, seeing as it will be useful for a lot of drilling.
would it not have been better to crack test the eye before doing all the welding? so that your not undoing a day or two of work if is it cracked beyond repair?
curious to understand why?
Excellent repair
Love Friday mornings when we get another video drop. Your video view counts are getting really impressive with 500k-1m views being pretty much the standard. I hope you are working on sponsorship deals. If not you are leaving pretty descent $ or at least product laying in the floor.
It's uncommon to watch UA-cam videos where the content is so professional, the presentation laid back, friendly and honest, and the videography, mixing, editing and overall post production is outstanding. What a team! Greetings from sunny Mornington Peninsula, (at least it was sunny today!)
I bought what I thought was "argon gas" for cheap, but it turned out to be "bargain gas" and it explote 😥
Yep plus Kurtis is so funny.. He has a great ego and approachable.. Very important these days.. Where can anyone find a guy with deep knowledge, does his research and has fun along the way.. oh and the videos are just great too.. thanks mate.. you have no idea what you bring to us.. so rewarding to watch all your video.. You have magic and with that thousand enjoy you much..
Hells yea brother, it’s so satisfying to just watch an extremely skilled individual do this hypnotic and satisfying jobs. They do great work with the tempo of the videos as well… LOVE this channel! But more videos quicker would be nice lol
So cool every boys dream is to play with big toys till we die haha
I first read that as Mornington Crescent 🥸
You make even the most difficult jobs seem simple, and the explanations are always clear, and I say this as a technician who has toured many construction sites both in Italy and in the world. Congratulations from Rome, Italy!
Wow thanks mate appreciate you saying so! Cheers
@@CuttingEdgeEngineering Do people brake many of these when you already have jig for welding it ready?
@@armageddontools i thought it must be a fairly common repair for him to have made a jig up for it. makes it nice and " easy" I bet that first one was a real pain in the butt, lol
I never appreciated how much work goes into this type of thing until I started watching this channel.
@@armageddontools This is the second bail arm he has done on his channel. He used the jig on the first one too. That one was only broken on one side though.
I always tell one of my sons, who tends to hurry, that “good enough” never is. This bail arm repair is proof positive that a well-conceived order of operations and thoughtful approach produces superb results. Brilliant, as always.
Well said!
@@CuttingEdgeEngineering ...but we have to talk about youre red&white penetration test... there where a lot of red dot ... i recoment to do a more "polished" surface and i think a 120 or 240grid wheel.
I even not understand what this sleeve's are fore and also not why you not do "steps" at the faceside of the tubes, like you did it on the cromerod's bevore welding?
In any case, watching you vids makes me tired like i'am working with you 🤣🤣🤣 ... best wishes also from Germany... Ahrvalley ...( floodet in july 21)
I love this. A person who believes in giving their customers superior quality and and elevated level of service. I run a small metal fabrication business here in Georgia and it’s satisfying to know, from the outtakes at least, that a universal language is spoken in our community. After studying your methods, I was emboldened to take on my first excavator bucket repair after 17 years of welding stairs and lighter materials. I did it like I thought you might and it came out beautifully! Thanks for sharing these processes and projects with all of us. And for the outtakes. Don’t edit those. We need that.
He is an education and an inspiration for sure.
... after watching just about all the videos from these two incredibly tuned-in people, I am compelled to make a few comments...
First, it is obvious this company has been set up for the long hall …
... the machinery and the supporting equipment is huge and is not cheep
... it supports mining and earth moving industries ... and challenges
coming from those are here for all to see...
... the confidence in 'attacking' any job by this chap, is commandable ...
... for a young man, the amount of knowledge, experience and "the know how" he has acquired is enormous by the look of things, and it will keep growing ...
... last, but not least, the lady's work with the camera, editing, inclusion of outtakes, makes this canal above the many on tube ...
...and the dog takes the cake ...
... as footnote, it would be a shame that all this experience does not get passed on to an apprentice ...
Cheers from Traralgon in Victoria
i will move to australia and become the apprentice
@@tedroddy ... you may laugh if you wish, but those are my thoughts ...
6:48
That moment that you anticipate Curtis's explanation about why he is going to weld the joints the way he does, BEFORE Curtis explains it.
A safety lesson, physics principle,welding methodology and quality statement in one.
That is the sign of a great teacher, when your students understand just how good you are.
Great work
hey mate appreciate that comment, glad the explanations make sense and are enjoyed 😎👍
@@CuttingEdgeEngineering
Team.... seriously the best 2 parter so far.
You guys just rock, better and better every, single time.
Always impressed to see Kurtis and his tack welds to hold things in place, most of them are stronger then most farm welds all over the world.
I plead guilty, your honour.
_"all over the world"_ you killed my ancestors and others with these.
Stronger than most welds I see in new equipment as well, by his needing to use a BFH to break them, instead of just a pinkie finger.
@Purple Runner what a stupid thing to say ... you clearly haven't been on any farms. Kurtis is great but I am + that he would not agree with you.
Can we get some customer reactions??
As an on toolmaker I want to thank you for your professionalism without all the me me mine mine. Top notch
I had no idea about welding until my grandson told me that he had some free time at uni and he was taking a welding course. Having no knowledge about what he was trying to tell me I discovered your chanell, and now after a few months of watching you I can sit in my wheel chair and feel qualified, maybe in my next life I will take up welding
Honestly the last 5 months I’ve been so bored with my job, January of next year I start taking welding class. Thanks to you for keeping me entertained and excited for a new journey in life!
awesome mate go for it! 😎👊
Same here. I got a job at a machine shop making all kinds of aerospace and medical parts. It's a great place to work but I don't see myself staying there for long. I'm starting welding school this fall and my dream is to start up a welding/machining repair shop
Good luck with your new journey!
@@LukeA_55 thanks! You as well!
I am a still Paramedic and Former Fire Chief and he has done the same for me! Wow! I have litterly watched videos in 3 hours with a small break because you have my attention at every moment! Great job! The honesty, work, doggone, video taking, editing and lovely funny outakes make this way better than ever I can describe!
With all the great work Curtis does, the hilarious outtakes, the great interaction between yourself and Karen while filming, everything is overshadowed by something far more important, Get well Colin in Berlin, best wishes mates
and that fade out at the end? Perfect!
They are a treasure, and I'll add my wishes too. Get well soon.
Wow Kurtis, I would never have imagined the bar could ever look so new again. 😄 incredible work as always 😍❤️😍
Thank you! Cheers!
@@CuttingEdgeEngineering Looks like it just came from the dealer!
CEE is normally the best start to my weekend, this weekend however I got called to work 45hrs of overtime. Amazing work as always and my two dogs always perk up with the random Homeless appearance.
"Now we're weady, for the tight quacks!" 😆🤣😂😈 Everyone's got jokes, until someone's feelings get hurt...... 😂🤣😆😈👍 Love to watch your content. It's very informative and entertaining at the same time. I like how you took time out to let one of your viewers know that things will get better. Thank you for starting this channel. I've been watching for about a year now, and haven't gotten through all the videos yet. Like you, some of us have actual jobs and contribute to society and our own wellbeing.
There's always going to be someone to get their feelings hurt, they need to go back to wearing diapers.
You guys are top notch. That bail arm was absolutely fucked and now it probably looks better than it did straight from the factory thanks to Kurtis having very good attention to detail. And Karen your cinematography and editing skills seem to get better every single video somehow
Then to top it off by include a stranger in the video to say your well wishes (I hope you get better Connie from Berlin)
True top notch work
Very interesting repair and well documented!
Btw, you can easily calculate the pressure inside the hollow bar after you've sealed it and you heat it up. You can use use the "Ideal gas Law" assuming a constant volume (the volume inside the hollow bar remains the same) : p/T = constant. Here p is the pressure and T the ABSOLUTE temperature in Kelvin (this formula only works if you use absolute temperature!). Assuming (conservatively) that you seal the void at a temperature of 293K (20 degrees Celsius) at 1Bar (14.5psi) pressure and heat it to 1293K (1020 degrees Celcius) you still only increase the pressure inside to 4.4Bar (64psi) which is nothing for a thick walled piece like the hollow bar.
This problem with exploding sealed chambers is only an issue with thin walled vessels like a sheet metal water/fuel tank. Those can, or at least will deform, explode under relatively small pressure like 4 bar.
Has anyone calculated what the burst pressure would be? I feel the non technical answer would be lots!
@@bryanlatimer-davies1222 can confirm. Did the math and the answer was indeed lots.
Or cheap tail shafts
I learned that the hard way 👍😎
100% correct. On larger material the risk is creating a blow out point on a hot weld, or a whole weld seam. Which can create a stream of high pressure gas escaping right where you're welding (with your in close proximity), or dislodging the work piece and have part of it fall (or fly) toward you..
Wouldn't a 1/4🍌hole like where the slip collar end is release the pressure?
Then when you weld the final end, just weld the hole up last
That is what I had to do when welding pontoons that had leaked. The pressure from the stem would blow out my weld so I left the hole let it cool then weld the hole
25:33 This kind of editing adds incredible amount of production value. Nice going camera/editor lady! You guys are killing it!😄
There's so much destruction, crap and misery coming out of Europe these days, it's so good to see a super happy company such as CEE producing fine quality repairs so that other Aussie battlers can continue working. Good Onya Mates!
Destruction? It's not 1890....
Is the piece he repairs from Europe? Or what are you on about
All three of you are just brilliant. Just one suggestion: Karen, it would be great to see and hear you more. Your cheerful good looks would be the icing on the cake...
Awesome work! I would love to see the clients reaction when they pick up the fixed part. Keep up the amazing work
I would love to see customer reactions and feedback. That’d be very cool.
Kudos to Karen she did a great job on those close-ups with the camera
Hey brother, i found your channel by accident and have been amazed by your dedication to your trade craft. i have been a plumber for 35 years and a 3rd generation plumber. i pride myself on quality and tradesmen's like work constantly. i am currently working just near you out the back of Yalata supplying infrastructure to future developments, and it frustrates me to no end how these operators treat these magnificent machines. Not mentioning any names but the way these guys drive em is a disgrace to your craft. ( it keeps you in work i guess ) my passion for plumbing, has aloud me to "never work a day in my life" anywho i have an English staffie as well, her name is Lucy and i call her the stone as she sinks in water like one lol. Hope ya had a great week, and cheers for ya vids
Hi greenmaster from Canada I spent my younger years ,about ten, operating these buggies and cats and I agree with you that some of the operators beat the boy jesus out of them. Some have no respect for the machine or the co. they are collecting a paycheck from. Some of the damage on the hoe buckets Kurtis repairs is in my experience unforgivable. Great job Kurtis and Karen Iknow how much work you put into craft and enjoy every video put out.
I hope you get paid good money sir for the work you do. You take pride in everything you machine. I've watched you do several repairs now on your channel and you never cut corners. It's hard to find anyone nowadays that does good quality work. That's why you're worth good money, appreciation and respect from your customers and I'm sure you get that from the majority of them. I bet they won't find anyone that makes better repairs. Thanks for sharing...👍👍
Couldn't have said it any better !!!
I'm sure he gets paid whatever he needs! Considering the quality of work, this guy would have a reputation that would bring customers from far and wide! He mentioned this rebuild was around $10k. This seems a very fair price for how well that was repaired and will assure him business for as long as he desires!
As a project engineer for Demmer Corp I was lucky enough to be involved with making up armor for Cat Dozers, the main beam and turntable for the Cat 24M grader and the frame rails for Cat trucks. Your work is at a level with the OEM. They charge top dollar and want to deliver at that level. You meet and exceed requirements.
Good job and half price of new is an industry standard for repairs. Considering they are able to pick it up in the morning shipping isn't an issue. Coming from the factories it becomes a major component of the part cost.
Love the little doggo. Better than most of the safety directors I have had the good fortune to deal with. 😁😎
I watch the whole video simply to watch the outtakes! Lovely message to the fan in Germany too 👍👍👍
I had to go back and watch the other bail arm repair series. Well worth the watch. Your explanation in both series is very easy to follow, and I thoroughly enjoyed every moment.
This series should be called, "What In Blazes Were They Thinking?" You're making this educational, entertaining, and I like it.
haha perfect series title right there 😂👍
That or

I was just about to make a comment on that the ball has to be the longest lasting toy that Hommie has had, then low and behold, he rips the black hand grip off.😂😂😂
Get well our brother in Berlin from your brother in Australia 👍👍👍
As a retired machinist in a shipyard, I have had to make repairs on all types of equipment. I can see that you take pride in everything you do and not cut corners. Enjoy all of your videos.
Тут бы не помешала кран балка,было бы очень удобно.Лайк однозначно.Вы очень умный и грамотный молодой человек,приятно смотреть на вашу работу.Ну и оператор заслуживает отдельной похвалы за технически грамотные ракурсы и не менее сложный и превосходный монтаж.Удачи вам .
A specialist can be recognized by the fact that the work looks easy and pleasant. A person thinks that even a child could take a job... Then you stand like a peg next to the element and look into the empty distance, wondering where to start. Greets :-)
A TRUE DAMN PROFESSIONAL! No short-cuts or half-assing anything. He does it the right way and safest way. Which more people worked like this guy!
Well thats actually.. NOT TRUE! Yes, he did do a GREAT job in general, but... NO shortcuts, mmm i wouldnt go THAT FAR. What about the collar end, that didnt get welded or even bondo'd ? I know its not a structural thing, but.. by sealing it, would have kept water/mud/sand from traveling IN the joint and thus, creating a weak rusty area "internally". Looks nicer also.
@@cumulusvapes7 Yep. That's a "real expert" comment if ever I saw one....
@@horsepants5848 Yep. I have been in the fab game for decades now,cant pull a fast one on me 😏
Hey Kurtis, you must have had a new/good bail arm in order to build that jig. It's amazing to see the rubble you turn into like new equipment, truly amazing!
I don’t know why, but I think this is my favorite video you guys have posted. I think it’s because it looks so OEM after the hard work and the paint job. Looked so good!
dude the fact that you figured out another way to do the job safely is testament to your commitment of excellency, meanwhile here I am can barely strike a match safely and thinking I'm Mr All that 🤓🤣
Really have to salute you for the integrity to show something went wrong instead of just carrying on and editing it out. Well done.
I have said it before, entertaining content from the first second to the last. CEE is an amazing team!
I so understand the time and patience it takes to do this type of work.
And Karen does an awesome job editing.
I was thinking about the patience to do a tedious job when I realized he would need to weld those tubes by hand. Would have been interesting to know how long he spent making those four welds.
Hi Kurtis and Karen, Now that's what I'd call a Top notch job and the fact you finished the job off by painting in CAT Yellow a true professional at work, Not some half assed geezer who threw in a bird that could shit wire 😂😂😂😂 , Stan Edinburgh Scotland .
Very impressive. I don't think many folks understand how difficult this repair is. Getting everything aligned, etc. And I would have never thought of the heated air in the tubing becoming an explosion hazard.
Kurtis and Karen, thank you for being who you are and sharing this with us. They two of you are so so good at what you do and we really appreciate everything that you put into your work and bringing us this kind of remarkable brain food and stimulating content. While it is a good laugh, the outakes show us the additional dedication and effort that you have and make for all of us. It's an absolute pleasure seeing Kurtis work and Karen bringing his work to UA-cam and supporting him in all that he does. You, including the Safety Officer deserve all the success and great things in this world. Thank you so much.
I couldn’t be further away from this line of work but I’ve learned more about welding and fab work watching these videos than I could imagine I would from a classroom experience.
one tip for the paintjob: hang it with a rod in the bearings on to your forklift. so can paint where needed in one step. i do it as well. i even have a specially made cover for my forklift. it has two holes for the fork and the forks are covered with two "socks", made of the same material the cover is made of. on the fork i attache it with magnets.
Honestly I believe the paint is just superficial and moot. The moment it’s used it’s going to rub the paint right off.
@@Someguy6571 your comment is moot as a toot.
needed CEE approved sticker for your good work placed on all your fixed projects for that seal of approval from CEE 👍
It does my heart so good seeing a real welder running wire vertical up. I watch time and again "fabricators" and "repairman" runnin downhill droopy ass washed out 3/4" wide weave passes, it makes me shiver. They spout off about "AWS says downhill mig is ok"
Bullshit!!! Anything over 1/4" thick needs uphill welds.
Thank you
Thank you
Thank you
For showing the world SOME welders do it right!!! 🥳🥳🥳
What a cracking job!! Your skills are endless Kurtis. Welder, gouger, grinder, lather, miller and spray painter - wow!
cracking is just what you dont want....
@@SupremeRuleroftheWorld ah, but cracking good toast sounds good, after a day of hard work. ;)
I hope he flipped it & painted the stripe from those stands, but looks good either way.
@@davidfloener7539 lol I wondered the same thing. I hope he did too.
your ability to immediately find the center of gravity of oblong shapes when lifting with the forklift never ceases to amaze me. also...yeah...every machining process you do is awesome too.
I dont work in any relatable industry to CEE but for the past few months I've been waiting for Friday so I can watch your new vids. Keep em coming
hey mate glad you enjoy the videos, thanks for watching 😎👊
I’m retired now but I worked as a millwright in the paper mills in the southeast U S and I enjoy watching you work! I love to weld a bit but you take it to a new level for me! Thank you Bro!🤙🏻
I have just started watching your youtube videos about a month ago. I used to work in a fabrication shop. I worked there for 10 years. We built bridge components. You are an absolute master of your craft. I love to watch your videos it brings back alot of memories for me. Now I just estimate bridge components.
Gday Kurtis and Karen, the bail arm looks brand new now, for how much punishment these take they do hold up well, taking the bit extra time to grind back the welds and blend it all into one is time well spent in my opinion, I’ve always wondered who sweeps the floor, well now I know, top job Karen, fantastic job as always mate, have a great weekend, cheers
Ps, all the best to Connie…
I’ve only just found your channel, but it has inspired me to drag my old little centre lathe out of the back of the garage and movi it to my workshop so we can use it. Thank you guys.
Welcome to the channel mate, go for it 😎👍
Neat and tidy as always !! I’m sure there would be a lot out there that still don’t realise how much weld you laid down there brother …
Love your channel
I’m 60 with endstage COPD type 2
Back in the 80’s my first job was at Glenroy Engineering in Bristol UK
Where is was introduced to Precision Engineering working with a load of old boys from Langston Thistle Bristol uk I worked on a lot of different machine tools imported during WW2
Captstan lathes
Centre lathes
Milwalkie horizontal milling
Vertical milling machines
External grinders
One such machine I worked on had a 20ft bed
The company made cutting rollers for the cardboard packaging industry like Cereal packs , cigarette packs and the like the level of engineering required was down to the 10 thousand of an inch so the factory was kept at 20*c 24/7.
I have always been in and interested in engineering ever since you sir are a bloody clever chap, I’m kept happily distracted for hours binge watching your videos thanks Mate from a fan in Blighty. Xx
Watch 19.29 at lowest speed Everyone...
Really cool show.🤩🤘👍
Fantastic video as always Kurtis & Karen. Thanks for mentioning the fan email, that’s what makes you stand out from other content creators. Hope you are doing well yourselves and have a great weekend.
Incredible work! Glad you remembered to put the sleeves on the hollow bar before jigging/welding!
Also, it would be interesting to do a test piece some time with some similar hollow bar and put a threaded port with a pressure gauge on it. Do a bunch of welding on it and see what kinds of pressure you get in there at what temperatures.
very good idea
Me personally would have forgotten
A shout out to my neighbor in Berlin, wish you full and speedy recovery as well. Greetings from Denmark
There's welders and then there are welders . you did a fantastic job Well done to you and your misses and your dog .
Great job Kurtis in repairing that bail arm. You're truly a master at your profession. I think this has been raised before but do consider to hire some young people or interns to help you out at your workshop.
That said, consider rigging up a local exhaust ventilation (LEV) SYSTEMS with positionable transparent hood to exhaust the harmful welding fumes. As you weld, the fumes would get extracted out through the ducting and into the fan and out through a chimney well above the roof.
Long term exposure (despite the help of a ventilator) to welding fumes can slowly and gradually seriously affect your health, and may cause cancer.
The LEV system can also be used to exhaust out fine dust during grinding operations. With a proper LEV setup, you may not even need a ventilator to supply fresh air to you.
I say this as an engineer and industrial hygienist with 27 years of experience.
Best regards from Malaysia.
Hey mate there is 4 of us on the CEE team!
You are an awesome fella .
Love to see that you have genuine interest in those who watch your videos
Always enjoy watching craftsman's at work and share their love and passion/,care for others
Karen I know a lot of people comment about your excellent production skills, but I just want you to know I particularly enjoy when you timelapse the video footage and keep the audio sounding the same so it looks like Kurtis is working superspeed 😂
I dunno how you do it but it's a really nice touch!
Ohhh the amount of patience and hard work you did in the video and behind the scenes just to get everything lined up and straight is just amazing
I was thinking about the weight if you used a soild bar, but making it the weakest link makes a ton of sense that I didn't think of.
Learn something new every day!
The really expensive parts ot this part are the ears and that forged arc that really takes the beating. That hollow tube is expensive enough but better to fail there. Just can't imagine how much stress is smashed through there.
You were very kind explaining why the replacement tube has a hole thru it rather than solid.
Your execution on bringing these big chunk of metals back to its original form is spot on. The repairs are as always top notch 👌💯. Thankyou CEE team for another very informative and great content. 👍 💯
I wish we could see the customer's reaction! Looks like a brand new part. Great job as always.
Haha, I feel the same way. I always wonder what the customers think when they get this stuff back. I'm regularly astounded by the quality of the repairs.
The customer is to busy to do reaction videos. He has 100s of machines and this is just another day for him. The real world is not like hot rod shows on TV, it's get it back together and working because we are losing money talking about it.
I actually learned a valuable lesson on this one. I am by no means a welder (metal sticker together guy) Never did I think about the pipe bomb affect when welding tubing. I will remember this forever now. Thank you
By using just ideal gas equation pV=nRT pressure over 5 atmospheres might build up there, if we start from 1 atmosphere, volume of gas in the pipe will be unchanged, as well as number of moles (n), R is gas constant....therefore pressure p is cca proportional to temperature....if we start lets say from 20°C and heat the gas to 100°C = 5x temperature would mean 5x pressure (in reality it is probably less)
and that hollow bar is like 1 1/2 inch ( 40 mm) thick or more. if you started at 20 C and the bar got to 300c that would be 15 times so 15 bar pressure . that tube would take 500 bar easy . so i think it exploding is a myth like the oxygen cylinder that broke a valve and flew a kilometer.
letting it cool down a bit is just more comfortable for welding
air pressure is directly proportional to temp. so 15 times the starting temp = 15 x pressure
@@ronblack7870 try looking up Lussacs Law and remember all pressures and temperatures are absolute, you might be surprised at the different answer you get

You are a very young person and my dad and I congratulate you for your work, you are a very thorough and capable person... greetings from Mexico in the state of Puebla
Kurtis, I've seen this several times and just now noticed the care with which you wiped the paint off the spherical bearing. Kudos for such instinctive attention to detail! Also, don't ever think you explain too much or go into too much detail; you explain exactly the peculiarities of the industry as they are presented to you in real life.
Another week has come and gone. My weekly dose of CEE is refreshing.
Love to time taken to make sure all is in alinement. Bit like measure twice, cut once.
cheers
Ian
Hey mate, definitely good to measure twice, or three times with jobs like these 😂👍
Amazing work Kurtis! True craftsmanship on display.
Well done Kurt... another fantasic job carried out to the highest level. The paint job really sets it off. 🏴🇬🇧
We had a great welder at work “Bongi” when we needed to drill deep holes for grease points in JCB arms etc. he would weld a rod to a standard drill and taking it slow and easy drill the hole with removal frequently for clearing swarf. Love the show excellent quality of work.
Very nice work. My late father made his summer job money running Cat Bulldozers in AZ/NM while studying Mechanical Engineering. He would have loved your videos.
Been waiting for this! Been watching too many - had questions about what was about to happen.... answered before I had to think more. Well explained.
That is an incredible workshop you have for a one man operation i always look forward to seeing the really good quality product you turn out see you next week
Stunning job, guys. Beautiful work, beautifully shot. What a team. You do a great job of demystifying your craft, Curtis, and I am, weekly without fail, in awe of your skills. With such a superb finished product it would be a treat to see some customer reaction when they picked it up. Any chance?
Im in the UK, just had a knee replacement and came across your feed. Wow! Have you kept this bodging wood butcher entertained! Your setup, knowledge and techniques are breathtaking. Love the videography, production and the lack of inappropriate music! The silent bridges with the most lovable woofer finding his chicken are inspired. I'm posting links i know folk who will love these as much as i do.
I believe one of the most dangerous pieces of equipment you work with in my opinion is that hydraulic press especially with a long drive driving pin pin with no safety barrier between you and the work I had my heart in my throat whilst you were pressing your one of the best techs I’ve seen only stating for your continued safety god bless
Great video and excellent job Kurtis. Nothing wrong with taking your time. Don't need it to blow up and get hurt or worse. Don't know why but about everytime get through painting something some kind of a bug get's on it. Saying a prayer for Connie. Y'all take care and I'll see you on your next video.
If you preheat the hollow bars to the temp that they would get to at completion of welding before sealing 100% with the tack welds, that could alleviate the risk of explosion due to temperature rise. Just thinking out loud for safety. :)
The calculation for temperature vs pressure rise for air (nitrogen) basically says as the temperature doubles, so does the pressure. Start at a higher temperature and the risk is greatly reduced. I would think the occasions where explosions occurred there was likely water involved. The change of state holds a great deal of energy.
Yes, from memory steam has seven times more energy than water.
That would take a lot of heat and time.
Temperature is in Kelvin. Doubling the temperature would be taking it up to about 300C. And that would make the pressure inside 15psig. Nothing to worry about.
You would need a metric shiton of pressure to burst that pipe ! That thing is thick as cannon and its not made out of weak mild steel. Ends would probably fail before pipe bursts. So no hiroshima.
Most likely the half-finished weld would be the failure point... best case it just blows out the last little bit when you're completing the first pass so it won't seal (preheating prevents this), worst case the pressure causes a weld to fail in tension whilst you're working on it. That's the dangerous scenario here. It's very unlikely that the tube would fail.
As satisfying as part 1 & 2 was to watch for me, I bet it was more so for you to craft this long and complicated repair and to see it come out as it did.
I know nothing about the video process, but I'm paying attention to it as much as the shop work. Re-watched a few of the older vids and the sophistication and expertise shows. Must see weekend viewing
I am a still Paramedic and Former Fire Chief and he and you has really got me really interested in this feild of metal working. Wow! I have litterly watched videos in 3 hours with a small break because you have my attention at every moment! Great job! The honesty, work, doggone, video taking, editing and lovely funny outakes make this way better than ever I can describe!
These have to be the best instructional videos I've seen. Clear, well explained and demonstrated with excellent video. Thanks.
When you paint, use a strip of 2" (51mm) masking
tape to make a sharp edge to pour over.
Put the masking tape about half over the top.
When you open a can of paint, use a very sharp,
straight slot screwdriver to poke a slot every 1-2"
in the lowest part of the sealing slot in the can.
These slots will allow paint todrain back to the can.
AND seal the can without extra paint gumming up
the sealing surfaces.
I have used this trick for over 40+ years as an automotive car painter.
This trick WILL seal the can air tight!
Your Pal, Gary
Good to know 👍
A good tip with masking tape to pour the paint. I used to make holes too and it helps when closing the paint tin but I found out one has to use the paint quickly as it somehow leaks air and after a year the paint was useless.
A friend of mine even used masking tape to seal the cap and he said it worked.
These are good tips for painting, but mostly wasted on Kurtis. He has the aversion to painting that is common to good machinists!
Karen, your editing skills are absolutely smashing. You make the video as much fun to watch as Hagerty’s Redline Rebuilds. Keep up the good work, and never stop improving!☺️
I am not an engineer nor do I operate or repair any kind of heavy machinery. But I enjoyed hearing from Kurtis about two things I would not have thought about:
1. The danger of the increased heat inside the cylinders (resulting from the welding) and the reason for not drilling an escape hole to relive the pressure (a hole produces a weak point).
2. The design considered the yoke as sacrificial; it is allowed to distort and break, saving a more expensive part of the machinery.
I appreciate all of Kurtis's comments about the how's and why's of his work. It is interesting even though I am not involved in heavy machinery. I can only imagine how valuable these videos are to those who use and maintain machinery.
Bonne soirée, Pour aujourd'hui, j'ai regardé 3 vidéos et ça va aller... J'ai l'impression d'avoir avalé beaucoup de poussière et de fumée de soudure pour terminer avec cette odeur de peinture. On a vraiment l'impression d'y être, quand on connait le métier... 😁😀👍
Great set of videos! My back and knees would be absolutely shot from all the up/down welding that thing.
Lovely job as always! If you haven’t seen it, have a look at the 3M PPS cups for paint guns, it’s so much easier and cleaner to work with, and doesn’t really cost any more money, just the time saved in my home shop was worth it.
Thank you so much Kurtis and Karen! You made my Friday, having to stay in bed sick during a vacation.
You made a beauty out of that wrecked bail arm! Gotta love your welding 🤩
Absolutely love watching these videos, let's the general public see that there is far more to welding/fabrication than most would first believe. 👏🏽👏🏽
Good job on the repair mate!
Quick little memo: I'm a bladesmith from Germany. If you preheat something to press back into shape make sure to get the part thoroughly red hot at the minimum if you can. Steel will behave differently depending on temperature and composition. But generally at temperatures around 300°C it effectively becomes more brittle compared to leaving it cold. We call that Blaubrüchigkeit.
I noticed you only had it red hot in the upper, outer area.
Now for transparency, I have never handled dimensions this size or at least of this size and material. The higher "quality" the toolsteel the more danger you face from "Blaubrüchigkeit".
Now of course I don't know the alloy composition of the the parts you handle. Maybe they can take it. IF you never had one crack before, I reckon chances are good.
But there might still be a risk of developing cracks within the material that never make it to the red hot outer surface because it can take more punishment during the pressing, that however contribute to a failure later on.
I thought I'd share that, maybe its nothing. We had some pretty unfortunate losses of parts and cutlery sometimes along the making of a knife or else even though one thought to have been careful enough.
Anyway, keep up the great work. I follow for some time now and the quality of the videos has made some great progress! Tip of the ol' hat to Karen! And to you of course on another job well done.
Party on :)
You two are just awesome. Not sure who comes up with the script, but its just so thorough and fluid. I really appreciate you taking the time and patience with all of us. I have learned a lot about this small section of industry by watching.
Such great engineering mate, you need an apprentice to carry on the CEE legacy! Fantastic job well done👏👏
Fantastic to watch as always Kurtis. Your skill in setting things up is as fascinating as the actual work itself. I now get two morning Australian engineering fixes, yours and the Australian Armour Museum!
awesome mate, we watch their channel and hoping to go visit the armour museum sometime!
@@CuttingEdgeEngineering Thanks, another channel subscribed to.....
Kurtis, Karen, & Homeless, That was/is great you give that fan in Germany a shout out, I’m sure it made his day! It made mine!
What I find absolutely amazing is the human ingenuity in making tools and manufacturing processes to built all the things we need and consume from light bulbs to spaceships. The utter cleverness of many of these machines and tools is stunning. Another great video.
