Hey mate thanks for watching! We didnt say in the video but had to machine off 10mm so about twice as quick to turn it down in the lathe. Was rough cut plate and wanted it true for welding setup as well. Cheers Kurtis 😎👍
I would have left the guard on the grinder, used two welding sleeves/gloves and removed the gas can from the welding table. Hopefully no one gets hurt in your shop
My dad was a tool and die guy machining repair parts for huge presses. Watching this video makes me miss him and respect what he did even more. I know he had to work within tolerances of thousandths of an inch. You all did a great job! Thanks!
My Grandpa was tool and die as well, probably smaller stuff in general. Aircraft parts for Boeing. Next time I visit him I think I'll show him this channel. His GF is savvy enough to use computers haha.
I used to reseal and install bearings into hydraulic cylinders at my old job. I can attest to obsolete parts! I once waited 9 months for a cylinder barrel. Had to ship over from Russia. Wonderful work man.
Worked in petroleum (and related hardware) for years...seen machinist work like this before, and even larger parts. Hard work, even with the right tools...but real craftsmen make it look better than new (and work better, too) when they are done. ALWAYS admiration for 'real skill'. I worked the 'advanced engineering' side of the slide rule, in the day, but if my kids were young now, I'd definitely push hard for them to have taken up trades (like machining) before dreaming of them going to college...trades are where the REAL WORK is done! Excellent video!
Great to see there is still skilled engineering in Australia instead of having the part shipped offshore to Asia for repair. Keep up the good work. I'm now a subscriber from the quality of both skill of the machinist and camera operator.
I have done hundreds of these over 30 + years. In logging these are common repairs. Some operators more than others. I used to keep many of these blanks for stock. I rarely had time to saw the weld taper off. Torch or plasma and get it done as a machine was down. No time for fancy work on the mill either. This blade tilt cyl couldn't care less if it looked good. Sound welds and function were primary. These ends were often sent to the mobile mechanics to install. The bore was done in shop and tuned to fit the pin with flap wheels after welding. No time for fancy when a road building contract was on hold till the problem was solved. 4 other pieces of machinery waited at big bucks as well. Sweet repair though !
Hey mate welcome to the channel! Our channel started 2 months ago but something UA-cam must have liked about it recently and is recommending our video 😅🤷♂️

Watching this artistry in metal is hugely enjoyable. Seeing terribly damaged, unobtainable parts beautifully restored to full working order by expert precision machinists is great, videos like this should be shown in schools to inspire new generations of craftsman and women. Thank you for taking the time to document your skills and sharing your taskings.
I've had one experience working alongside heavy machinery, and that really opened my eyes for the rest of my life. What five people lifting together couldn't even budge after an hour of digging, a loader with one prong of the front scoop hooked under a girder ripped out of the dirt like it was nothing. It's seriously hard to imagine just how powerful hydraulics can be.
@Heads Mess I THINK it's better to use something that's compressible, so if a rock or something gets into the track, rather than something breaking, the piston is able to compress the grease and make room for the rock.

Very nice video...thanks for reducing the boring to a less 'boring' amount! Nice Mill, no big holes drilled in the table....yet.... I worked as 'The Welder' in a machine shop...we had a big heavy equipment rental yard across the street, no shortage of hydraulic cylinder work. We had one guy spent his while day just doing the seals and piston rings. Lots of rod eyes on cylinders and rod ends...some big stuff...some cylinders were 12"...5" rods with big Clevis welded on there...quite a few extension cylinders from Cranes.
@@CuttingEdgeEngineering I just found your channel... I've been 'retired' for 8 years...since I was 65...No one hires guys my (that) age in industrial shops....no matter if you can do the work...even if you're in good health, like me....but I still like watching this sort of stuff....! The Shop I worked at had about 10-12 guys, days...2 at night...I welded all day...about 1/2 the time I was doing exactly what you're showing with hydraulic cylinders/rods...the other 1/2 was various other destroyed equipment...you know...'run it till it breaks, then fix it'.... We did some 'medium sized' stuff.....had a couple big lathes...one was a Nardi, about 108" swing...42 foot bed travel...guy sat on a chair on the carriage and ran it from there.... Other one was around 80" swing but 50 foot or so on the bed... 96" Blanchard Grinder...We could flat grind a 4 X 8 Steel plate... A couple vertical lathes..Bullards...a few mills, Bridgeports, 2 radial-arm drills...Carltons. Biggest problem was everything was hammered...these guys bought every one else used up stuff... Even the 2 big Lincoln welders were barely working...Lucky I'm pretty good elec/electronic guy...and can fix them....and the other stuff...like the 5 and 20 ton overhead bridge cranes that didn't work...
Это хорошо когда такие станки и оборудование есть в наличии.... Многое сделать можно. С таким оборудованием выточеное и приваренное ухо - рядовая работа.
Nice work mate. No chatter from that little boring bar and fitting that part in a 3 jaw chuck was well done. I did my fitting and turning apprenticeship in Melbourne, but left the trade after a couple of years to work with music. Still use the skills all the time (in many ways) and am really glad to have be taught by the old fellas who had so much skill and knowledge. I still have all my tools that I hand made at trade school 40 years later. Thanks for posting some quality Australian content.
Hey mate welcome to the channel thanks for watching and commenting! Always great to have an Aussie supporter. Definitely a handy skillset to have. Cheers, Kurtis 😎👍
Работа красивая. Есть пару нюансов: 1) допускается ли применение сварного соединения в данном узле агрегата?; 2) наличие дефектов сварки, выходящих на поверхность, не снизит надёжность данного изделия?
Exactly! In (marine) crankshafts the lub. oil ports in pins and journals are reamed and polished to avoid failure of the part due to the roughness of the bore after drilling.
I can already tell the sequence of events leading up to the original eye breaking: CAT operator: boss, this part needs to be replaced Boss: whatever, just use it till it breaks -5-10 minutes later- **SNAP**
Most the stuff we repair at work (mainly crushing and mining stuff) gets run till is totalled. Then we get the fun of trying to get it back to factory tolerances. Most cases it’s because it’s not worth the time/money to strip it down for preventative maintenance.
@@Wyllie38 yeah I have run glass recycling plants 150,000 ton per year, same gear as aggregates. Glass just obliterates despite ceramic, ar400, chrome carbide, every time we plan maintenance it's delayed.
Jim Glass yeah. They normally keep spares either from us or elsewhere... run it till it dies. Stick the spares in and then get us to fix the parts that’s been exploded www.reddit.com/r/Skookum/comments/9wy8ki/next_on_the_agenda/? Abit like this
Hey I just went back and watch this this must’ve been one of your first videos that you put out very informative but I love it when Kurtis starts explaining stuff in swears and especially when you start putting Homeless in all the stuff
I cut the eye off a cylinder once because the piston had unscrewed and wouldn't retract all the way so I could remove it from the mount. Just about got fired because of it. I figured someone should be able to weld an eye back on there. Cool vid thanks for posting.
@J.C. Kohle No J.C. It actually, looking back 30 years, was 2 ears with a pin hole through both. I cut it off because the piston had come off the rod. I pushed the rod into the cylinder as far as it would go. As I tried to tip the cylinder out of the mount that was inside a frame member, the ears hit on the top of the frame member that the cylinder was in. I lopped the ears off with a torch and tipped the cylinder out. The next morning the machine was running and warmed up for the operator when he got to the job. I learned about 5 years ago from a fellow mechanic that the boss asked him if he should fire me for it. If I had the steel and a drill that could bore 1" holes and a new piston that wasn't completely buggered up, I could have fixed the cylinder myself if I had the time. No, didn't touch the cylinder or rod, just the little ears off the end of the cylinder. Thanks for commenting.
I breathed a sigh of relief when the first shot is you cutting the damage off. Some of the ways Y'all repair stuff makes me feel dumb and inferior in the welding skill level department. Love the videos.
Great job. Smart to make the piece over size so he could mill to get it all square. I love fixing stuff and making stuff. I’m not that skilled for sure
Why so many dis-likes? Looks like quality work and decent repair to a layman. If the dislikes are simply because it's a weld and not a total replacement - then they are just ignoring the explanation given.
Really cool work on that cylinder. The finished result is good as new. I'm sure you saved the customer a fair bit of cash versus replacing the whole assembly.
A fine job on that repair. I am viewing from Missouri, USA and I have great respect for the work you do! I am guessing that it is cost effective for a repair like this due too several possible reasons? 1) Cost of a replacement part from CAT, or if it is even available any longer? 2) Cost of importation to AU? 3) Down time for the customer to be without his/her machine on the job site? 4) Shipping cost do to weight & size? Thanks for the quality photography, the slow motion is awesome! Cheers
Hey mate thanks very much for watching and taking time to comment. You're spot on as all of the above are contributing factors to why the customer went with us doing this replacement repair. My misses does the editing can you believe it's all recorded on just her Samsung galaxy S8 phone! Cheers, Kurtis 😎👍
It must be a thing, I'm in Mo too and watching. One question, why no coolant on the fly cutter, or the boring cutter? always helped me keep from burning up tools
Super interesting to see the comparison from where you are now to where you were... obviously your work quality hasn't changed, but the addition of commentary etc :D Love the videos, slowly going through all your old stuff too!
Watched a few of your vids now. I don't subscribe easy so that says a lot about you & your gig. Very impressive. Love your precision mind set. Your bully is awesome too. Such a happy dog. Great chanel. Rock on Bro.
The UA-cam algorithm sent me here after binge watching Abom79. WOW! Great to see a Qld company turning chips. I'd like to see if a video on your precision tools used in the workshop - Mitutoyo v Starret etc.
That was worrying me as well. The first face was not crucial as there was plenty needing to be removed, and the bore would be perpendicular to the machined face. But it would be reassuring to see how the machined face was made flat to the table after turning it over. I suspect that you could have easily got within spec using a workshop level rather than indicating. You'd obviously reference the table with the level first. I still think that the only crucial spec would be the bore diameter though.
@@TrevorDennis100 No, the pin bore Dia is critical, but ALSO it being perpendicular to the piston bore, that is very important or the rod end and this pin will not be parallel and you won't get both pins in.
@@integr8er66 Both ends get a spherical bearing When the blade tilts its actually a pretty serious twist put on it In line is ideal for long life of the bearings more than anything but its not uncommon to come across bent rams that are working fine
@@CuttingEdgeEngineering That would be nice to see more of the set-up, but many of us already know how most of that is done...maybe throw a few set-ups in every 3-4 videos? Or hey...just show us a 12 micrometer or 24" caliper....then we know you mean business!!
I really enjoy your channel, it lets me see repairs and procedures that I would never otherwise see. I noticed that your videos have become more polished and professional. However, I have to say I miss your dog and your wife's comments. Please bring back some of those friendly vibes as they are missed.
@@CuttingEdgeEngineering My iPhone music looks like the play list of a psycho! 😂 and I listen as such too. To pass time at an old job, the 10 of us would try to out do each other with a radio station playlist that would be insane, with hilarious outcomes! For instance, “You just heard from Frank Sinatra with “My funny valentine” coming up next, another timeless tune the Prodigy with “Smack my bitch up” 🤣🤣🤣 Needless to say, it was hilarious and made standing out in the snow, freezing for no reason a welcome distraction. If you try it, you’ll laugh till it hurts to hear what comes up.
Hey friend new subscriber from U.S. I'm enjoying your work vids.Learning alot.But I would pay to learn only one of your many welding skills.Peace.Be Safe.
I'm currently in school to become a Millwright (mechanical fitter) I'm finding a lot of useful information just from watching what you do, and I'm able to recognize different things the amount of sparks coming off the steel during grinding, is a high carbon steel. I'm happy I found this channel!
Wow, this is impressive. So great to see it being fixed, and fixed WELL. That is not going to break again in a hurry. Great skills on show here, those interrupted cuts on the lathe are not easy to get right. I kinda wanted to see it in action again though. :-)
I don't know why he used, but I would do the same in my shop because it would be a faster set-up and a cheaper tool to wear out. I in general would prefer Lathe over Mill when removing big amounts of material for those reasons. Also I would feel more at ease to put the late in the auto and go do other things nearby as he did. I wouldn't do the same in the mill (what efectivelly saves time). And as an extra the mill could be occupied at the moment by other operator or other set-up. Being a very time intensive machine the mill is usually being used. I have three in my shop, but the good one is always occupied with someone else set-up.
And in addition to all that there is the fact that it is easier to fix the part by its sides (chuck jaws) in the lathe than in the mill. So you can align the facing operation almost perpendicular to the walls of the part. In the mil you usually have a cut parallel to the oposite side (in a standard clamping the part on the table set-up), maybe the operator in the video didn't trusted the oposite face to be perpendicular to the walls. And as he didn't want to machine the lateral walls (other than the weld chanfer), maybe this is one reason too. And if you want to face the whole part you will either fix it by its sides or you will need to fix one side, then face mill, then loose the fixation aparatus and fix it in the other side of the part to face mill the rest of the part (Always avoid that if possible as it can move the part, specially when the oposite side is not machined yet).
A very interesting video, thank you! I have, as usual, some questions :) 1. On the interrupted cut, your depth of cut is quite significant, I was wondering if that is actually better than a shallow cut in terms of lifetime on the insert, especially the tip? 2. What are the advantages of turning the faces down to size instead of using a milling machine? A big thank you for your ever insightful replies, it is great to learn more!
I was wondering the same thing about facing the new eye. I have no experience machining but I imagine that turning process eats a few bits up fairly quick as opposed to milling flat. Hope he answers!

А, разве, не остались в зоне сварных швов огромные нескомпенсированные напряжения после последовательного заполнения швов без прогрева противоположной стороны? Может, правильнее было бы попеременно заполнять швы?

Good Ole dual shield. I've always said I've never seen better penetration than 45 wire dual shield. Worked at a beam making shop and we used that and we were throwing half inchers on 4 inch plates and flanges.
An old timer once told me; “always buy a used caterpillar. Then most of the problems will be fixed. Buy a new one and you’ll spend all your time fixing it”
@@biggestbruh3780 when you fix the part your fixing the initial problem that made it fail in the first place. You’re making it better so to speak. That’s what he was talking about. All the fixes on the used machines are made better than the original if done correct. The repair in this video is a great example of that.

Very nice video...thanks for reducing the boring to a less 'boring' amount! Nice Mill, no big holes drilled in the table....yet....
I worked as 'The Welder' in a machine shop...we had a big heavy equipment rental yard across the street, no shortage of hydraulic cylinder work. We had one guy spent his while day just doing the seals and piston rings.
Lots of rod eyes on cylinders and rod ends...some big stuff...some cylinders were 12"...5" rods with big Clevis welded on there...quite a few extension cylinders from Cranes.
Hey mate welcome to the channel thanks for watching and commenting. Very nice that would've kept you busy for sure 😎👌
@@CuttingEdgeEngineering I just found your channel... I've been 'retired' for 8 years...since I was 65...No one hires guys my (that) age in industrial shops....no matter if you can do the work...even if you're in good health, like me....but I still like watching this sort of stuff....!
The Shop I worked at had about 10-12 guys, days...2 at night...I welded all day...about 1/2 the time I was doing exactly what you're showing with hydraulic cylinders/rods...the other 1/2 was various other destroyed equipment...you know...'run it till it breaks, then fix it'....
We did some 'medium sized' stuff.....had a couple big lathes...one was a Nardi, about 108" swing...42 foot bed travel...guy sat on a chair on the carriage and ran it from there....
Other one was around 80" swing but 50 foot or so on the bed...
96" Blanchard Grinder...We could flat grind a 4 X 8 Steel plate...
A couple vertical lathes..Bullards...a few mills, Bridgeports, 2 radial-arm drills...Carltons.
Biggest problem was everything was hammered...these guys bought every one else used up stuff...
Even the 2 big Lincoln welders were barely working...Lucky I'm pretty good elec/electronic guy...and can fix them....and the other stuff...like the 5 and 20 ton overhead bridge cranes that didn't work...
3rd time watching this and I'm still in awe the amount of time and skill that this takes
Это хорошо когда такие станки и оборудование есть в наличии.... Многое сделать можно. С таким оборудованием выточеное и приваренное ухо - рядовая работа.
Да, потратив много денег на оборудование и инструменты, я согласен, что значительно облегчает работу

Nice work mate. No chatter from that little boring bar and fitting that part in a 3 jaw chuck was well done. I did my fitting and turning apprenticeship in Melbourne, but left the trade after a couple of years to work with music. Still use the skills all the time (in many ways) and am really glad to have be taught by the old fellas who had so much skill and knowledge. I still have all my tools that I hand made at trade school 40 years later. Thanks for posting some quality Australian content.
Hey mate welcome to the channel thanks for watching and commenting! Always great to have an Aussie supporter. Definitely a handy skillset to have. Cheers, Kurtis 😎👍
Работа красивая.
Есть пару нюансов:
1) допускается ли применение сварного соединения в данном узле агрегата?;
2) наличие дефектов сварки, выходящих на поверхность, не снизит надёжность данного изделия?
The grease port that extends life was the same port that ended it.
Exactly! In (marine) crankshafts the lub. oil ports in pins and journals are reamed and polished to avoid failure of the part due to the roughness of the bore after drilling.
yes, mostly eye fracture start from grease port
And from lack of use for its intended purpose.
I can already tell the sequence of events leading up to the original eye breaking:
CAT operator: boss, this part needs to be replaced
Boss: whatever, just use it till it breaks
-5-10 minutes later-
**SNAP**
it took weeks and multiple requests :D
Have worked in multinational companies that actually demand run to fail.
Most the stuff we repair at work (mainly crushing and mining stuff) gets run till is totalled. Then we get the fun of trying to get it back to factory tolerances. Most cases it’s because it’s not worth the time/money to strip it down for preventative maintenance.
@@Wyllie38 yeah I have run glass recycling plants 150,000 ton per year, same gear as aggregates. Glass just obliterates despite ceramic, ar400, chrome carbide, every time we plan maintenance it's delayed.
Jim Glass yeah. They normally keep spares either from us or elsewhere... run it till it dies. Stick the spares in and then get us to fix the parts that’s been exploded

great satisfaction for the owner of this machine shop.
Hey I just went back and watch this this must’ve been one of your first videos that you put out very informative but I love it when Kurtis starts explaining stuff in swears and especially when you start putting Homeless in all the stuff
I cut the eye off a cylinder once because the piston had unscrewed and wouldn't retract all the way so I could remove it from the mount. Just about got fired because of it. I figured someone should be able to weld an eye back on there. Cool vid thanks for posting.
HAHA that's bloody brilliant
@@CuttingEdgeEngineering I had thought about cutting the rod off. I wonder how the boss would have liked that.
@@ralphwatten2426 you should have said. lol "well boss it was eather the eye or the rod so i chose the cheaper of the only two options"
@J.C. Kohle No J.C. It actually, looking back 30 years, was 2 ears with a pin hole through both. I cut it off because the piston had come off the rod. I pushed the rod into the cylinder as far as it would go. As I tried to tip the cylinder out of the mount that was inside a frame member, the ears hit on the top of the frame member that the cylinder was in. I lopped the ears off with a torch and tipped the cylinder out. The next morning the machine was running and warmed up for the operator when he got to the job. I learned about 5 years ago from a fellow mechanic that the boss asked him if he should fire me for it. If I had the steel and a drill that could bore 1" holes and a new piston that wasn't completely buggered up, I could have fixed the cylinder myself if I had the time. No, didn't touch the cylinder or rod, just the little ears off the end of the cylinder. Thanks for commenting.
I breathed a sigh of relief when the first shot is you cutting the damage off. Some of the ways Y'all repair stuff makes me feel dumb and inferior in the welding skill level department. Love the videos.
Great job. Smart to make the piece over size so he could mill to get it all square. I love fixing stuff and making stuff. I’m not that skilled for sure
Hey mate thanks for watching!
geez, i can watch theese repair videos all day lon,,pure magic
with that material thickness...its mandatory to do pre heat before weld, post heat after weld and NDT examination (x ray or MT)
And if I’m not mistaken he used FCAW which he shouldn’t be pushing the weld pool he should be pulling it
Why so many dis-likes? Looks like quality work and decent repair to a layman. If the dislikes are simply because it's a weld and not a total replacement - then they are just ignoring the explanation given.
Really cool work on that cylinder. The finished result is good as new. I'm sure you saved the customer a fair bit of cash versus replacing the whole assembly.
Hey mate thanks for watching and commenting 😎👍
In a thousand years these videos will still be high-tech and high-skill
A fine job on that repair. I am viewing from Missouri, USA and I have great respect for the work you do!
I am guessing that it is cost effective for a repair like this due too several possible reasons?
1) Cost of a replacement part from CAT, or if it is even available any longer?
2) Cost of importation to AU?
3) Down time for the customer to be without his/her machine on the job site?
4) Shipping cost do to weight & size?
Thanks for the quality photography, the slow motion is awesome!
Cheers
Hey mate thanks very much for watching and taking time to comment. You're spot on as all of the above are contributing factors to why the customer went with us doing this replacement repair. My misses does the editing can you believe it's all recorded on just her Samsung galaxy S8 phone! Cheers, Kurtis 😎👍
@@CuttingEdgeEngineering The occasional slo-mo is great - especially on the interrupted parts.
Hey mate You're going to like the next videos coming up then! Some slow mo interrupted cuts in action 😎👍
@@CuttingEdgeEngineering can we also see the face mill in slow mo? thanks!
It must be a thing, I'm in Mo too and watching. One question, why no coolant on the fly cutter, or the boring cutter? always helped me keep from burning up tools
Super interesting to see the comparison from where you are now to where you were... obviously your work quality hasn't changed, but the addition of commentary etc :D Love the videos, slowly going through all your old stuff too!
Seeing the "I Love Dad" picture in your work area was the best part of the video. You must be a great dad and role model to your youngster. Kudos 👍👍

Watched a few of your vids now. I don't subscribe easy so that says a lot about you & your gig. Very impressive. Love your precision mind set. Your bully is awesome too. Such a happy dog. Great chanel. Rock on Bro.
hey mate thanks for subscribing we appreciate it!
The UA-cam algorithm sent me here after binge watching Abom79. WOW! Great to see a Qld company turning chips. I'd like to see if a video on your precision tools used in the workshop - Mitutoyo v Starret etc.
Hey mate welcome to the channel! Appreciate you watching and commenting. Will put that down for a future video idea thanks! Cheer,s Kurtis 😎👍
I used to break things like that on the farm. "Hey Dad, it's okay, just a little 'damage'." LOL
🤣👌
It was still in one piece, not totally broken.
that repair is like 100x stronger than original part 😁 good job 👍
Another Awsome job mate I don’t really think most of us don’t understand the Amount of work goes into fixing these Pieces 🥰👍👍🦴🦴🦴
I wonder if you could show some of the set up, like the indicating and locating? Very interesting. Thanks
Cheers buddy will keep that in mind for future videos!
That was worrying me as well. The first face was not crucial as there was plenty needing to be removed, and the bore would be perpendicular to the machined face. But it would be reassuring to see how the machined face was made flat to the table after turning it over. I suspect that you could have easily got within spec using a workshop level rather than indicating. You'd obviously reference the table with the level first. I still think that the only crucial spec would be the bore diameter though.
@@TrevorDennis100 No, the pin bore Dia is critical, but ALSO it being perpendicular to the piston bore, that is very important or the rod end and this pin will not be parallel and you won't get both pins in.
@@integr8er66
Both ends get a spherical bearing
When the blade tilts its actually a pretty serious twist put on it
In line is ideal for long life of the bearings more than anything but its not uncommon to come across bent rams that are working fine
@@CuttingEdgeEngineering That would be nice to see more of the set-up, but many of us already know how most of that is done...maybe throw a few set-ups in every 3-4 videos? Or hey...just show us a 12 micrometer or 24" caliper....then we know you mean business!!
I like the fact that your newer videos don't have the music tracks.
Pakistany truck guys would fix that in 10 minutes with a stick welder and a grinder.
Hahaa no doubt 😂👌
And it would last 10 seconds!
Yeah. And phuk up in 10s
And sandals
And break it again after 1 hour. Lol

Hey mate welcome to the channel! 😎👍
I'm really glad I found this channel !!!
Enjoyed watching that job over my coffee break ... nice work team.
Hey Bob thanks for watching glad you enjoyed! Cheers 😎👍
I really enjoy your channel, it lets me see repairs and procedures that I would never otherwise see. I noticed that your videos have become more polished and professional. However, I have to say I miss your dog and your wife's comments. Please bring back some of those friendly vibes as they are missed.
Jewel - “Who will save your soul”
Not my first guess on what metal worker’s listen to at work. 🤣🤣🤣
You should see my Spotify playlist 🤣
@@CuttingEdgeEngineering My iPhone music looks like the play list of a psycho! 😂 and I listen as such too. To pass time at an old job, the 10 of us would try to out do each other with a radio station playlist that would be insane, with hilarious outcomes! For instance, “You just heard from Frank Sinatra with “My funny valentine” coming up next, another timeless tune the Prodigy with “Smack my bitch up” 🤣🤣🤣
Needless to say, it was hilarious and made standing out in the snow, freezing for no reason a welcome distraction. If you try it, you’ll laugh till it hurts to hear what comes up.
Yes I couldn't be sure I'd heard it right. Good machinist and good musical taste. Perfect.
Hey friend new subscriber from U.S. I'm enjoying your work vids.Learning alot.But I would pay to learn only one of your many welding skills.Peace.Be Safe.
Dont be trashing jewel!
Truly amazing how much force it took to break that piece! And now we're going to have fun making it look like factory.
That is one sweet mill you get to run, nice work!
I'm currently in school to become a Millwright (mechanical fitter) I'm finding a lot of useful information just from watching what you do, and I'm able to recognize different things the amount of sparks coming off the steel during grinding, is a high carbon steel.
I'm happy I found this channel!
Wow, this is impressive. So great to see it being fixed, and fixed WELL. That is not going to break again in a hurry. Great skills on show here, those interrupted cuts on the lathe are not easy to get right.
I kinda wanted to see it in action again though. :-)
Профессионально сработано ,Браво!
I have a question, why did you use the lathe for the initial face milling of the plate instead of the mill?
I don't know why he used, but I would do the same in my shop because it would be a faster set-up and a cheaper tool to wear out. I in general would prefer Lathe over Mill when removing big amounts of material for those reasons.
Also I would feel more at ease to put the late in the auto and go do other things nearby as he did. I wouldn't do the same in the mill (what efectivelly saves time). And as an extra the mill could be occupied at the moment by other operator or other set-up. Being a very time intensive machine the mill is usually being used. I have three in my shop, but the good one is always occupied with someone else set-up.
And in addition to all that there is the fact that it is easier to fix the part by its sides (chuck jaws) in the lathe than in the mill. So you can align the facing operation almost perpendicular to the walls of the part. In the mil you usually have a cut parallel to the oposite side (in a standard clamping the part on the table set-up), maybe the operator in the video didn't trusted the oposite face to be perpendicular to the walls. And as he didn't want to machine the lateral walls (other than the weld chanfer), maybe this is one reason too.
And if you want to face the whole part you will either fix it by its sides or you will need to fix one side, then face mill, then loose the fixation aparatus and fix it in the other side of the part to face mill the rest of the part (Always avoid that if possible as it can move the part, specially when the oposite side is not machined yet).
Brilliant work right there !
Your customers are lucky a guy like you carries out their repairs.
A very interesting video, thank you!
I have, as usual, some questions :)
1. On the interrupted cut, your depth of cut is quite significant, I was wondering if that is actually better than a shallow cut in terms of lifetime on the insert, especially the tip?
2. What are the advantages of turning the faces down to size instead of using a milling machine?
A big thank you for your ever insightful replies, it is great to learn more!
I was wondering the same thing about facing the new eye. I have no experience machining but I imagine that turning process eats a few bits up fairly quick as opposed to milling flat. Hope he answers!
Nice to see a workshop video where PPE is taken seriously.

@@CuttingEdgeEngineering Amen
A fixed part with 1 brand new part versus everything brand new. Yea dunno that old timers pretty delusional
@@biggestbruh3780 when you fix the part your fixing the initial problem that made it fail in the first place. You’re making it better so to speak. That’s what he was talking about. All the fixes on the used machines are made better than the original if done correct. The repair in this video is a great example of that.
