Line boring & Bore welding CAT 740 Truck A-frame | Sir Meccanica WS2

- เผยแพร่เมื่อ 26 พ.ค. 2022
- In this video we are line boring and bore welding to repair a Front A-frame off a Caterpillar 740 Articulated dump truck. The main pivot position on the A-frame is worn out so we are line boring and bore welding to bring the bore back to size to fit a new spherical bearing. We are using our Sir Meccanica WS2 portable in-line boring and bore welding machine. First is setting up and tack welding on the bearing mounts for positioning the line boring machine. We need to line bore out the material before bore welding to build up new material and then boring out to spec. We also chamfer the bore and drill in the grease port. The job is completed by cryo freeze shrink fitting the new bearing using liquid nitrogen.
In this video we are using:
- Sir Meccanica WS2 Portable line boring machine
- WIA 500i Weldmatic welder

Kurtis, you have become a throwback to why I started watching machinist videos. My favorite machinist have become talkers and not doers. You talk just enough to let us know what’s going on. Your skills are phenomenal.
Hey mate thanks for the feedback, to put it simply, no time to F*ck around here lol talking isn't my strong point 🤣
@@CuttingEdgeEngineering Yeah we see that every week in the bloopers...ROFL
@@CuttingEdgeEngineering No thank you for the content. I also hate videos with kids dogs and cats but your dog cracks me up and makes me smile.
@@CuttingEdgeEngineering talking is overrated. My son and I communicate quite well with grunts and snorts. Love ya work mate.
He's an aussie - no time to fuck spiders.
But yes, I sometimes wonder if Abom lost his machinery :D
What I love about CEE is that you are just running your business and Karen brings us along for the ride. You aren’t doing this for views. This is great. Keep going!!!
Thanks mate we always wanted our channel to be real life in a real workshop 👍
For once an operator that stopped the machine before something was totally destroyed.
Great job :-)
p.s. Ta. That sunset was a real beaut, just what I needed to see on a Friday morning in the UK :-)
Gee, a company that said "Let's get this repaired before it blows up"
Как приятно смотреть на то, как вы своими золотыми руками делаете по-настоящему качественный ремонт,которого так мало в сегодняшнем мире
Уже долго смотрю Ваш канал и постоянно радуюсь за Ваш великолепный труд. Вы очень молоды ,но Вы отличный мастер... специалист своего дела.. Очень рад за Вас. Просьба - информируйте нас и дальше... Собачка - просто прелесть !!! RUS
Hoping everything is going well down there. Take care. Steve
The level of care and quality of work is awesome. It seems some trades are all about the quick, cheap and often wrong way, that just breaks sooner, but CEE is the real deal.
yeah I think it's the combination of our name/reputation and being a 1 man workshop that takes things to that level not many go to these days
Being the boss can really take the care out of the craft.
Love the outtakes. It’s refreshing to see someone confident enough to say FUCK. You crack me up. Thanks for the video’s. Oh ya, Fuckin Awesome machinist. 👍
Kurtis you have a mind boggling depth of knowledge aswell as the best and most patient camera woman on TH-cam. Great video.
thanks mate we both appreciate it
I don't have any fancy lathes or milling equipment but I have watched almost every video. I have learned so many techniques for my fabrication projects and have learned that almost everything can be repaired. truly a gift to watch you work and teach us all. Cant wait for more merch to be back in stock !!!
Hey mate that's great to read glad the vids have helped in some way. 😎👊
If it can be made, it can be repaired.
Fri 3/6/22 My fix, my fix! Where's my fix!!!
Great job, as usual, Kurtis. I've had to repair some bearing holes on large hydraulic cylinders when the owner let it get to the point the bearing broke down, literally in pieces and pounded them into the housing. Needless to say, now the job became a real bastard as hardened bearing chunks were embedded in the housing, couldn't be machined out, couldn't weld over them. Had to cut the part off and make an entirely new end. Entirely needless work. Keep up the good work, love watching a pro work.
It is amazing how smooth the bore weld is with that marvelous machine. A wee bit more and you could skip the boring op. LOL!!
Karen, You just keep popping closeups and other video techniques that keep me coming back to see what new twist you've mastered.

we legit have the best community on youtube!!!
I've said before, and I'll probably say it again, the line borer, welding machine is so versatile, it is amazing. To try and set that A frame on a horizontal borer would be a pain and would take a long time too. I did notice that the line groove was not machined, having it on the hearing makes more sense. Great job and see you next week. Grass looks good after your rain.
hey mate thanks for taking time to watch and share a comment, glad you enjoyed it! Now grass will grow like crazy, still a bit muddy in spots
@@CuttingEdgeEngineering Playing hide and seek with the dog - who by the way was not allowed to open a present today
@@CuttingEdgeEngineering Yeah, too wet to mow here in the Wide Bay and the grass is getting longer every day.
Karen is the Brains. I wanna see flowers, flowers and more flowers.
she is in charge of the books so will give herself another pay rise 😂
This past Friday I was looking forward to the next video after work, but no video, the weekend is about over and still no video.
I hope y’all are ok because you normally post each Friday!!
Anyway looking forward to your next post!!
Ron
Stayed up till 3am to see this
bloody hell mate you made it to the #CEEAddicts club 😂👍
Same. 2:11 here. Perks of being self employed.
I'm just amazed at how good this channel is. I can't see a single thing I'd change. The only thing better than watching your videos is watching your sub numbers go up. Can't wait for 1M!
Kurtis deserves 2 million. :)
Thanks very much mate we really appreciate it 😎👊
Always love to watch when you are line boring and then building it back up. Retired welder.
I know we all come to this site to enjoy the Skill of the Guy doing these jobs, and to see how he tackles the various jobs, but this is a shout out to the great camera work. Very professional job. 👌
I enjoy the linebore/borewelding videos probably the most, because its so far removed from small part machining :D
Thanks for sharing!
For someone from a non engineering perspective i have learned so much from you in the last 12 months. I love your work, so interesting. 🙂🚜🐻 Bear Queensland Oztralia
awesome mate thanks for watching
It's the little things, like noting that you're spraying oil onto the warming bearing to keep ice from forming and causing rust, that are so valuable for youngsters just starting out to know. Love watching you work!
Man, the liquid nitrogen gets me every time, it astounds me how much something like a metal can shrink or expand depending on the temperature. It's so cool.
As always another great video guys, Kurtis you really are top tier in you craft, and love how you share your tips and tricks, if you ever decide to go that way you would make a great teacher.
I’ve said it before and I’ll say it again the CEE team really do create content that is second to none👍🏻well done! 👏🏻
It really amazes me how you know that equipment so well that you can set up the speed, feed, volts, amps and anything else that needs setting, and complete a perfect bead in one pass.
Great job.
Once you have done a job a few times it becomes second nature with feeds, speeds, amps etc. But, I have to admit Kurtis does appear to be silky smooth with his set-ups.
I'm glad man law from the US is compatible with man law in Australia.... It's illegal to put a ratchet strap on something and walk away without twanging the tightened strap whilst saying some variant of "that's not going anywhere."
Another solid video Kurtis and Mrs. Kurtis. The work is great but I'm also loving that the video production (shots, post fx, editing, etc) get incrementally better each video. Great way to start my Friday
I feel the urge to smash a like button every time Kurtis answers my silent question, like it was with the oil groove :) Tons of respect for the quality of your work. It's very inspirational!
Every time you introduce one of these projects I ask myself: would it not be easier to use a mill and then I'm reminded how quickly you're able to setup the line bore tool and how you can use it as double duty for weld buildup. Always very cool to watch, thanks for sharing.
I absolutely love his boring bar setup. I wish that I had had one back in the day. What a time saver.
Love the pro & con discussions! Like, what does the Argon do and what you don't like about the borer.
And am amazed by the amount of knowledge that is stored in your head, such as "0.2mm undersize will get the bearing about as tight as you'd want it to be". Those are things you either get right or wrong, and no retries. Only experience can teach that.
The bearing fit is determined by the diameter of the bearing. Roughly .001" per 1" of diameter. Also the type of fit required. How tight it has to be retained and the bearing clearance has a determining factor. If you have to much interference on the fit ( the bearing being bigger to much bigger than the bore it goes in ), you may be able to shrink the bearing into place , but the bearing won't rotate.
This is better than "Thunderbirds Are Go"! God bless all three of you.
Anything can happen in the next half hour!!!
Kurtis,you could have been a professor. I find myself intently following your video lessons as though I were preparing for an exam. You are logical and thorough. Your style makes me want to learn.
I am not a machinist and, at age 75, I never will be. But,if I were back in high school, I think you would have been my best teacher.
Snap !!
I don't know about being too old. We could probably get a couple of good years out of you yet. Not in industry but definitely as a hobby machinist.

Miss your weekly video Kurtis, do hope your both okay.
Read the channel's Community Post from 4 days ago. Their taking a small break. Peace and chicken grease!
Hey mate yeah all good we're just taking a break from TH-cam this week so we can catch up on work
@@CuttingEdgeEngineering Thanks for the udate - I did'nt catch the notice you made regarding your being off air. You deserve a WEB. Enjoy
You handel that Liquid intergenerational with ease it gives ME THE WILLYS 🤯 KUHL JOB .
I was relieved to see you load test that ratchet strap!
Good video. It's amazing in a short period of time your videos have gotten so good. The filming is excellent and the explanations are spot on, thanks for teaching us so much and the entertainment. The one legged chicken was fun
Awesome, thank you!
I love the confidence you have to showcase your work on TH-cam. Always good work, good explanations, and walk-throughs. Good work!
When you stood the A-frame upright, I thought "He's gonna wanna support that!" See. I'm learning😁👍🏻
Karen sure makes you look slick with the editing on your intros then you're slick on the tool's, nice work by you both.
One man show but a two person team 😆
My youngest is a heavy equipment mechanic , he just started back with Finning Caterpillar at the oil sands in Ft McMurray . Seeing the component parts of these machines in for repair gives me some idea of the size and complexity of what he is working on .
Kurtis, another fantastic job with Karen's' expert filming & Homey providing security.
Hey mate! Have a good weekend
@@CuttingEdgeEngineering You too
Who doesn't like a frozen bearing install on a Friday night. Mind you just send the bugga down here next week top temp 8c. As always thanks for a great video Kurtis, Karen and Homie. 👍🍻
shit mate that's fresh!
@@CuttingEdgeEngineering spanner weather mate. Tightens the nuts. 👍👍
Have you ever thought about licensing your videos out as a teaching aid?? Your explanations are instructive, clear and concise.
Don't forget to include the out takes in the curriculum! 🤣It would keep those wannabes coming back to class!
Kurtis has mentioned previously that some teaching staff are using his videos with permission. Mind you permission and licensing are two different things and a lot of teaching institutions are always short of money, so I don't know what the answer should be. Perhaps if they buy some merchandise from CEE then things will be sweet.
aye love the videos. I watch every single one but the NEW video editing techniques are absolutely spot on. keep doing amazing 😊
THANK YOU!!!
Once again, a TRAIN stuffs up your video, I can just imagine how many times people waiting at level crossings have said that to me whilst I was driving my train pass them😆😆😆
Beautiful sunset, you arranged that sunset well KAREN 👍👍👍
I just love watching other people work, ha ha. Kurtis and Karen, thanks for sharing.
Your like a one man army version of Pakistani truck channel 🤣🤣🤣
with bonus steel cap boots!
@@CuttingEdgeEngineering 🤣🤣🤣
And power tools.....
Karen, I really appreciate the videography and editing -- you're great at telling Kurtis' story cleanly and succinctly, without "boring" us non-professionals. When you use longer timelapses, would it be possible to overlay a time counter in the corner (or elapsed time at return to "normal" speed) to give us an idea how long some of the operations take? (Putting a clock in-shot would be just too much faffing about.) Thanks!
Hey Mike thanks for sharing feedback and the suggestion will see what we can do 😁👍
There was one video that Kurtis machined the outside of a long tube because he didn't like how it looked when he machined in the places for clamps. During that long machining process you showed the lathe doing its thing while also showing Kurtis doing other jobs around the shop. THAT was a great illustration of just how long some jobs take and that more than one job can be worked on at the same time.
Maybe a shop wide view while a job is being done showing what else is happening around the shop would be interesting. And if it's speed up, more entertaining. Nothing like watching people walking around super fast.
You know one thing is homeless his lines are always flawless
By the way I love watching your shows thank you
That's why he's the star of the show 🤣🐾
I learn alot from the videos, but I stay for the out takes!!!!
Nice tip on not placing the split on the load points.
Glad to help
I co:e here to learn and be entertained. And I’m never let down. Kurtis, your work, as usual is absolutely amazing. Karen, I’m not sure what new techniques you’re using, but the videos literally just keep getting better and better! Thank you and have a wonderful weekend! Cheers!
Thanks mate good to see your comment here 😁👍
Everything I wanted to say has been said below. I'm just commenting to bless the YT algorithm. Excellent video (as always)!
Nice to have a part come in at least intact. Great work, love the line bore and weld. Another great video of real craftsmanship Kurtis. But the real credit is to Karen for her great camera operation and editing. Can't forget Homeless, he makes the show. 😊
Have a great weekend. 👍👍👍
Of all the types of repairs you do, I find line boring to be the most interesting and fun to watch.
awesome glad you enjoy it mate
Great profissional job Kurtis 👏👏👏 Greetings from Portugal
AS a fellow Portuguese I have to say I love his videos despite not understanding a thing about machining, milling and boring
Awesome video as always. During the out takes I was stunned by that beautiful Australian sunset. Holy hell we don't get many like that here in South Carolina.
It’s just another shitty day in paradise mate.
Hi Kurtis, Karen & Homie, another great video & fantastic editing, seamless.
Inspiring workmanship.
Would be great to see how some of your projects are progressing, guess you are flat out with work.
i grabbed some mech for me & the wife.
A fellow fitter that is a little rusty ...
Cheers
Not enough words to describe how amazing your work is Kurtis, and the filming + editing from Karen is spot on, love you guys - Again cant wait for next one ❤️
my daughter is just getting her own youtube channel started about her and her 1984 harley davidson bobber. she was just recently approved for monetization. i use you folks as a constant reference on what it takes to put together a well done and thoroughly informative video. the outtakes really show the quality of editing and commitment to perfection that go's into your channel. thanks for all the effort you folks put in.
that's awesome congrats to her for achieving monetization for her hard work! Appreciate your support mate
Do you have a link or the channels name?????
@@AlessioSangalli here is the link to her videos , thanks for the interest and enjoy th-cam.com/users/RedRiderCanadaBCvideos
She may be ever present eye, always watching, and lovingly judging, but the editing and camera work also seems godly. Great work woman, man and dog
The hours you put in are incredible. Do you ever get to go home in the daylight?
They split those bearings with hydraulics, using a mandrel with a wedge forced into it to split the bearing at a score mark with a sharp edge, machined into the surface. For the single side ones you just have the single score mark, and a cage to hold it when it cracks, and then you use the elastic range of the hard tool steel to pop the cryofrozen ball in, there is just enough elastic range to get it in. If it breaks it was going to fail NDT anyway, as there was an inclusion in there somewhere
WOW this was GREAT info!!
The little clip of split screen was cool you should do that more to show us how stuff is being done on the lathe that would be really cool :)
will see what I can do! Thanks so much for the feedback 😁 Karen
I love that you started to do the extra effort and show us where the machine the parts you're working on are attached to and also explain what the part does and what forces it has to handle.
Kurtis thanks for explaining things too us.I enjoy your videos. Thankyou.
Karen Fantastic job of filming the videos. Thanyou also.
Now Homey you done well catching the runaway chicken. Good job.
GO TEAM AND. 😀😃🙂
The editing and production quality on this one are awesome- the welding sequence especially.
It always a great day when the plan works out exactly how you plan it.
Thanks for showing quality line bore but going the extra step of showing when and how that large part is.
Kurtis standard = something heavy enough you must use a crane.
Homeless is the star. He never f**k a line ;)
That's why Homeless gets all the fans and gifts 😂 thanks for watching each week mate
No matter how many times I see it, that machine still amazes me. You have a lot of expensive quality machinery for a fella so young. And you certainly know how to use it. I am continually impressed. And all of your work looks like industrial jewelry. Big slap on the back from an old man in Ohio (retired machinist welder fabricator).
I really like all the videos because there are videos behind the scenes ..
The video is late today... hope all is well down under......
Hey mate all good we're just taking a break from TH-cam this week so we can catch up on work
@@CuttingEdgeEngineering Glad all is well and looking forward to your next post.
Gynecologists must be great lineborers - they are used to work in confined places ;)
Guess I'd be quite scared if he moves to welding the bearings to your thighs *eegk*
Did l tell you . I'm a self taught gynecologist. I don't know much about it. But I'll look into it for you..... Sorry Karen... I know. It's a family show.
I've helped many friends do many bearings on their vehicles, and many of my own where I've put the new bearing in the freezer before we started working on the car... then, when ready, heated the knuckle / housing with a propane torch before massaging the bearing in.
Watching you literally DROP that liquid nitrogen-cooled bearing in place makes me question my worthiness! 😆
Karen, a very nice video! And a split screen! Cool.
Thanks Kurtis, Karen and Homeless,
Kurtis have you ever experimented with using shoulder bolts and jam nuts to mount your linear borer to use a longer reach without as much deflection with the increase in shoulder diameter? Just had a pain of a brain fart... oh what a relief it is...
Nice RC Copter in the backyard
Another excellent video. The use of split screen in editing is a nice touch, good work!
Glad you liked it!
Hello Kurtis,
SORRY I have been on the missing list... back in action now, As always thanks for an entertaining video and have a great weekend...
Take care.
Paul,,
I like the way you guys treat every job , do the job until it's done ( hence the total darkness when you took it outside) rather then the 5 o'clock finish most service industries work too, I have worked to both rules and much prefer your kind, awesome job as always, keep it up, and we will always be back for the next one....Hans
oH YES, Fridays repair vid. awesome.
😎👊
Yay, been looking forward to this all day. Gidday Kurtis, Karen and Homeless from Auckland :)
Hey mate! hope your week was a good one
Bom dia no Brasil boa noite pra vocês, seus serviços são excelentes Kurtis, gosto muito e aprendo muito também.
KAAAHHHLLLL, at 4:00, when you ask about the single-split-race spherical bearing assembly: 20+ years ago (taking machine night classes) I had the opportunity to take a graveyard-shift tour of a bearing factory near Trenton, NJ (in the USA), they manufactured spherical bearings of all sizes up to around 16". The answer to your question is that they use a hydraulic press to push the inner race into the outer, the whole thing was surrounded by a steel cage/box, and sounds like a bomb going off when the outer race snaps back. The operators got a KICK out of seeing all of us young guys jump! I believe it was an 8" or so bearing. Keep up the good work👍-Andy
I think you need a big CNC boring mill. Yes, it would mean a huge concrete footing, shop modifications, a ton of expensive tooling and fixtures but...now hear me out...it would be really cool. 😁
Excellent work as always! Good to see that "goin nowhere" test. The safety officer would certainly approve.
So far away from anything I might ever get involved with, may as well be a NASA job. Wonderful to watch
thanks for watching and enjoying!
Hell yeah waited 7 days for this vid 🤙🏼🤙🏼🤙🏼
Hey mate thanks for waiting and watching
@@CuttingEdgeEngineering always watching, I’m a bricklayer and have almost a full machine shop setup as I thoroughly enjoy machining, hoping to switch trades 1 day in the future
The muddy ground, and the sky at end looks like down here in Lake Macquarie today. I hope things dry out now. Feels like we didn't have a summer. Thanks for putting up another video. Great job, as usual. 👍
Going through withdrawal here, I’ve watched this 3 times now.
Nicely done. As they say. The quality of the job is always in the set up or prep... Do a good job there and the outcome will be 110 %. Great content as per x
Well said!
Great stuff as always, good way to round out the week.
Glad you enjoyed it
@Mason De Galle • 🤣🤣🤣
I see what you did there :-
_"round out the week"_
Goes exactly to plan. The immense skill and knowledge Kurtis has makes it so. Great video and editing again by Karen. A very talented, wonderful couple. Thanks to you guys and pats for Homeless.
And a lovely sunset to close. Thanks, Karen.
Gday Kurtis and Karen, it’s been a while since I seen dry concrete up there, It would be interesting to know how the single split is put into the bearing, don’t think I’d would have liked to been there when the line boring machine got destroyed, beautiful sunset at the end Karen, have a great weekend mate, Cheers
Hey Matty yeah mate was good to get some blue sky finally! The humidity and moisture in the workshop has been shithouse. Yeah felt bad for the guy, was a rookie error that cost him a fair few dollars. Chat soon mate, cheers
right n time as usual.......cheers from the other Sunshine State, Florida,.......wishing you all the best......Paul
Hey Paul thanks mate for always being one of the first to watch
@@CuttingEdgeEngineering it is my passion......thanks for sharing your skills with the rest of the world.......best wishes, Paul
Karen, you've gotten very good at capturing this type of industrial video. Between videography and editing it's clear what the process is and the actual work of it.
Thank you very much
"Rather than just wack a new bearing in there and send it on its way, we're going to repair this thing correctly!" - Wise words that could've saved many an expensive piece of equipment! Greetings from the UK!
G'day Kurtis, Karen and Homey great video and Karen love the time laps of the welding. Looking forward to see the shop finished
Karen also likes the time lapse welding shots, kind of hypnotic. Hoping to get our container shelter (igloo) up soon, had to wait for all the rain to fuck off! Then we'll get the shop update video uploaded
@@CuttingEdgeEngineering Yes the fucking rain I have had it. Here we are ankle deep water or mud for two month strait now
👌👍 Great !. Camara Lady you must have a lot of patience! 😁🤣😂😅
Yes I do! 🤣
It is always a pleasure when you get that line bar out. Thanks again Kurtis.
Top shelf work as always !! Your customer saved a ton of money with this line bore job as opposed to buying a new part !! Fantastic work as alway's !! Love Homies one legged chicken also !! 😂😂👍👍
