Electric Motor Shaft Repair | With Lathe, Welding Machine and CNC-Mill

[@Beyondthepress]

And yes my t-shirt is backwards :D And if you like this and haven't seen my "Repairing bearing housing" video here is link kzbin.info/www/bejne/r3u6ZYaKfraJZq8 Since you can do this process also to bearing surfaces on rotor this is bit like part 2 of that video and with these you can repair all bearing surfaces on electric motor.

[@c2h3cl82]

Beyond the press Relatable :D

[@Beyondthepress]

but it's my fault doing this video with out Anni :D She would correct my t-shirt for sure :D

[@c2h3cl82]

Beyond the press Lol

[@danny3man]

hey man, i really like your channels, but can you please enable the subtitles? the auto-generated ones? it would help us those with bad "microphones".

[@johndowe7003]

its ok, i wear my shirt inside and out and backwards too lol

[@sloth0jr]

The real work you do in the machine shop is often a lot more interesting than the simple "press 'n' explode" stuff you started with. I think you do a pretty good job of narrating what you're doing.

[@ckbooks]

This is such skilled work. It's always fascinating to watch a professional craftsperson doing their job.

[@panza.]

"craftsperson" :/

[@markstrickland438]

Great video, Lauri! Please post more like this one!

[@MickyFoley]

Ok. 3rd time I try to write, because KZbin tends to load another video in the background. Crazy. Anyways: I learned to do this many years ago and know, how frustrating it can be to get the correct diameters by hand. No digital tool - just measuring by hand. I repaired motors, generators and transformers for a living (yes, also did the winding). Great video and I'd really love to see more of them. Sure, exploding stuff is fun, but for us mechanical people, such videos from you are highly welcomed! Thanks for it and greetings from Austria.

[@VIPER410]

It is crazy how much goes into a repair you don't think much about it till you see it. Thanks for sharing Lauri

[@teunje]

Great video! I'm a mechanical engineering student, sadly we mostly do theoretical learning. So it's very cool to see these videos in a shop, since we don't get to do a lot of that.

[@jasonswift7098]

Lauri is a machinist not a mechanical engineer.

[@teunje]

Jason Moyle I know. But both have a great overlap.

[@kdawg3484]

As an engineer by trade that works in a place with an actual shop that builds complicated things, I can tell you with 100% confidence that you will learn more as an engineer by watching and learning from welders, machinists, pipefitters, rotating equipment technicians, electricians, and the like than else than anything you'll learn in school. Learn what they do by reading and watching. Learn to draft, and learn to communicate well through your drawings. After all, these guys and gals are the ones that build what you design. If you don't take into account HOW what you design is going to built, then quite frankly, you'll be a shitty engineer. And there are lots of shitty engineers that don't have a clue about this. I'd say most, in fact, are like that, and a lot of that is because they've never seen anything actually get built, so they have no clue. That's no excuse, though. You seem to already be on top of understanding this, though. That's a HUGE step up on all your peers that you already have. If you know how things are built and how much they cost, your designs will be so much better than anybody else's. I mean, that's what engineering actually is: optimization of design, implementation, and cost. You'll be an excellent engineer if you realize there's so much you DON'T know and so much you need to learn. And stuff like what Lauri's doing in this video is a great example of stuff they'll never teach you in a formal curriculum. Knowing that is a huge advantage to you and will make a great engineer. Good luck.

[@HydraulicPressChannel]

Jason Moyle I have just couple math courses and masters work left of my master of science degree left some I am kind of mechanical engineer also ;)

[@teunje]

Awesome advice man! Thanks!

[@Maxbroforce]

It says a lot about that you care enough to make even a regular repair job perfect and do a beautiful job on the machining! Thanks so much for sharing some 'regular work' videos and giving us a chance to see your top notch skills in action. It's always great to see a professional do their work and make it look 'easy' even when it's really complex!

[@CampyCamper]

really interesting video, you explain everything really well

[@JimN5QL]

I enjoy this kind of stuff just as much as the goofy stuff! It is so fascinating! Thanks for sharing.

[@TheSourKraut]

Precision machine work and repairs are THE most relaxing thing. If you watch someone else do it. Thanks for the video!

[@gmcman355crazy]

For being Finnish you speak English good enough for this American. Good work !!!

[@marcmckenzie5110]

I enjoy watching a variety of people solve machining challenges - I learn new things all the time! Nice job.

[@youpattube1]

You are very nice people, and it is a pleasure to watch and listen to you. I went to college in the upper peninsula of Michigan and got to know many Finnish people who live there, and who's parents and grandparents came to America at the end of the 1800's.

[@stacyreid5077]

Great to see you at work. I had an idea of machinists work but didn't know that you could re straighten a key way like that. Thank you

[@Danofcanada]

Lauri is so bad ass he's going to have a terminator 2 funeral. "you must lower me into the steel"

[@3k31000]

haha!

[@DoktorStrangelove]

🔥👍🔥

[@aaronsmith8073]

👍

[@heathersanborn4914]

That's some cool shit , my grandfather is a machinist has three old Bridgeports and a multi tool newer like from the early 90's new milling machine and he has been doing it for some 50 years , I help with deburring and do small welding and fabrication jobs for him that's what I went to school for and auto mechanics

[@hilltopmachineworks2131]

That's neat.

[@perniss4145]

Love all of your videos. I work in a workshop aswell and your workshopvideos inspire me alot. and the big plus is that you can easy click your way to the crushing vidoes. Love it.

[@milksheihk]

It's amazing seeing that work done, at my job they'd scrap a motor armature thad had damage like that to the shaft.

[@Beyondthepress]

These are so cheap now days that quite few companies get these fixed anymore. Usually it's when motor has some special dimensions and delivery time is really long so it's much faster to repair old one. But motors 2-3 this size are still much cheaper to repair than buy new one.

[@Your_username_]

Or if the new motor is very expensive. Big electric motors tend to cost tens of thousands of € or $ so its more cost effective to repair the old rotor than just buy a new one.

[@rickb9238]

This kind of work is a very skilled trade and hopefully the kids today will continue to go into these trades. Skilled trades are needed and always have been. I think the fact that you are showing this kind of repair is a learning lesson for some young adults that may want go into a trade like yours.👍👍

[@biometrix1000]

Absolute Artist in your work...a pleasure to watch Lauri. .thanks for sharing your talent..

[@claw-machinesNL]

Reminds me of when i used to repair things like this, nicely done and a lot of information. I like to watch things like this.

[@thomaslohr2864]

I enjoy crushing frozen lake videos a lot but this is also pretty good too. I really like this type of content!

[@TheNARF86]

More of this , i find it relaxing in some way ...

[@alexwitteried3893]

It wasn't until he kept calling dial gauges "clock thingy" that I even remembered english wasn't a natural language for him. This content he awesome.

[@budburr66]

Metal spray is magic!

[@kirkh4205]

It's really interesting watching these types of videos because I used to work in a machine shop. I started by just operating/reloading then moved to setting up the auto-saws for chopping bar-stock into thousands of pieces. Eventually I got good at setting up and working the Bridgeport hand Mills. We also had a hand Lathe on which I would turn things I think they called it Zooble. Most of the machines were my age or older than me (i was born in 83). We had a lot of Mazak and Funuc machines but the most impressive machines were the two late model HAAS (obviously). I cant remember their model numbers but we had a small one that was the size of a honda cr-v, and a large one that could almost fit a honda cr-v inside it. Lol if the table were not inside, the car would fit. I understand the X,Y,Z axis and how to Indicate the work piece to the turret but I never learned how to program/edit the g-code, I went on to continue my automotive tech career. Lol I notice that when he can't think of a word in English he just calls it a "thing" which works fine. I can't speak any Scandinavian language but I'm only the 3rd generation born in the US, before that my Grandpa's parents came off the boat from Sweden. Anyway, I think the "clock thing" is called a Dial Indicator. Really interesting shit.

[@dougdegraff5892]

Your “Clock Thing” in English is a Dial Indicator.. great work.

[@peacefulsurfer]

Was just doing the same a couple hrs ago with a centrifugal's shaft, though went through Tig welding to build the bearing surface. Something relaxing about the process.

[@kirkkohnen5050]

Lauri, that is truly a work of art!

[@PurityVendetta]

We're just about to start repairing damaged shafts. We call that method of welding flame spraying here in the UK. I really liked the tip using soft copper strip to true the work in 3 jaw chuck.

[@mrracer98]

Enjoyed this a lot! More welding, machining and let's see your welding table please.

[@wazhoola14]

Loved that, fascinating. Would've been nice to have seen a before and after shot alongside each other but that's just me being picky, keep these coming, love it.

[@ReneChaddock]

This is more interesting than most of your stuff. Please consider doing more. Thanks.

[@thebeststooge]

Thank you for doing a serious, and professional, video finally.

[@medtechfire22]

Honestly have always wondered how this work is done. Looks really satisfying. Keep up the great work!

[@gmcman355crazy]

Love this video . I'm a machinist and love seeing others daily projects at work

[@McFingal]

gun-nut257 why no 4jaw chuck? The cringe factor was very high.

[@gmcman355crazy]

M/V WRETCHED BEAST I didn't say no 4 Jaw lol I use one abour every day

[@FrontSideBus]

I must say that I'm enjoying these workshop vids. Wouldn't mind seeing more "real work" videos...

[@jonsey3645]

This was awsome to watch! The fact that I was able to show my beautiful wife that you weren't just an explosives nut was priceless. Thanks for a great channel.

[@BlackEpyon]

This is Abom79 stuff here. I'd love to see more "Workshop Thursdays."

[@themadhillbillycustoms5013]

I really like these workshop videos! Keep up the good work.

[@jackedup8790]

I think this is one of my favorite videos. Thanks

[@stridermt2k]

Beautiful work! The company I work for does similar work in our motor shop. I stand in awe.

[@craighudson1827]

Really cool video! I use a wood lathe, so I was familiar with a lot of what you said, and a lot was new. Very different than wood turning! I liked your water hose

[@mdrew44628]

It will be good for another 50 years.....great video....

[@danielesantoru2591]

THAT'S MAGIC. PERIOD. PLEASE SENPAI TEACH ME.

[@JackdeDuCoeur]

Very nice work! So cool to see how it's done.

[@445cat]

Great Vid! Love these behind the scenes type. Honest and great work.

[@blindbrick]

We had an damaged shaft with deep groves where the bearing should be. So we send it to a shop with the comment, "we want a new shaft with dimensions like the old one". two days later we got the "new" shaft with exactly the same damage like the old one.

[@mikakorhonen5715]

blindbrick blindbrick Damage is new normal.

[@saiprasadrm97]

LOL!!!

[@ilmarinen79]

On kyllä tosi hyviä nää työskentelyvideot!

[@mejulesyap]

After a long day, this was quite therapeutic to watch :)

[@brianhilligoss]

There is a couple of reasons for the coolant to change color. It’s either the ways oil mixing with it or water evaporation from the coolant tank. We use to check the coolant daily with a hydrometer and used multiple oil skimmers in the coolant tanks. I worked on 3 TOS Varnsdorf mills and 2 TOS Hulin Vtls.

[@panza.]

Mielenkiintosta settiä!

[@numbr6]

Excellent craftsmanship. Thank you for sharing!

[@dylantrerise3844]

Lauri is god damn man he’s massive and works in a machine shop you’d fit right in here in America

[@Avitaser]

Machine some Lauri-designed shotgun slugs and have Taofledermaus shoot them on his channel as a collaboration video...that should be impressive!

[@Puzzleguy]

Love real work videos, but my 5 years old son likes when you crush something.

[@HammyTechnoid]

Super Precision is always best.... then you know it's right and not screwed up... *GREAT DEMO*

[@AnianBrosig-yv3jn]

every time I watch one of these Videos I want to become a machinest myself as well :)

[@lomparti]

Very very interesting. Thank you for the upload

[@djviper79]

I really enjoyed that, thanks Lauri

[@ProfRonconi]

Excellent work. I want more videos showing your actual, day-to-day work. Of course, I also enjoy the zanier stuff, but real work is always more interesting.

[@Cleand-ruggies]

Great workshop video, im thinking I should try machining.

[@carlmayne3519]

That was real interesting ... I do love watching videos on how things are made and repaired ... :D

[@OldmanXan]

I love this type of video, Keep up the good work and make more of these types of videos.

[@billbussler3332]

I think it's ok to just call the "clock thing" an indicator. Or even dial might be better than clock thing lol. Great vid!

[@duffysgunsmithing2585]

i liked clock thing but indicator is correct. sometimes finnish doesnt translate smoothly to english.the word for it in finnish is probably 37 letters long.

[@WoodworkerDon]

Dial Indicator or Run-Out Gauge are both common.

[@nikolaiownz]

It's a heimer 3d taster aka 3D edge finder 😆

[@mbsnyderc]

Micrometer Dial indicator.

[@jinksonyou]

And again, awesome job! If I watched every video (working on that) I could open my own shop! Hahaha

[@kramsniggah4333]

Great work Lauri

[@planetrob555]

Wonderful! Keep making these!!!

[@EmptyPocketProductions]

"shit load of error" lmao, you are awesome! Great work, thanks!

[@lvmybears]

12 years working in tool and die.The following day after september 9/11 i was laid off along with half of my coworkers.Decided to never go back to working in a machine shop. afterwards.It was the right decision.

[@a.s.vanhoose1545]

We love Finland here in America

[@SmallMartingale]

Love the machining videos!

[@jix177]

Great job, very well explained. Thanks!

[@AMBowers29]

I run the tool crib now. This is how I get my fix. I miss getting my hands dirty.

[@00BillieTurf00]

I like this sort of video that shows your skill, thx

[@lorchid23]

I love hearing you speak 😍

[@tinldw]

So that's the one I forgot to watch. Good video, actually.

[@enviromentalny]

Different metals or otter shit... those pesky otters!

[@insfazegunni8656]

I´d like to give a lil tip. The 3-D Taster is not for rubbing against metal i would recomend a fine pointer to do that leveling part. Since the rubbing part is wearing that pointer and the whole tool is getting inaccurate.

[@Beyondthepress]

I have so many "ups" moments with the thing that I snap the rubbing ball thing always before it get's any wear :D

[@insfazegunni8656]

Know that feeling =D pain in the ass to get it workin again

[@Beyondthepress]

My tool changer is also so violent that the longer tasting heads just snap with in some amount of tool changes :D Probably 6 months of use and it will just fly away on tool change :D

[@Cornelious.P.Drabnar.Esqire]

I wish i was not too old to learn this kind of work

[@powderdtoast69]

just started a machining job myself!

[@karlomoharic3992]

Have you ever tried TIG welding ? It's great for this type of stuff because you can really control the puddle and the amount of material deposited.

[@karlomoharic3992]

Also no spatter with TIG

[@mogwix]

Is the new filler material softer than the original shaft material? will the key way wear out sooner after it has been repaired?

[@simonedmunds8732]

Very interesting and informative. Thanks

[@waynep343]

i am thinking that cutting a second keyway 180 degrees out would give the tech a second spot to wear out a keyway before sending the motor in for a repair.. or use 2 keyways by broaching the pulley or coupling a second time. i wonder about drilling the coupling at an angle to put some dog point allen sets screws in to preload the keyway at an angle. in stop and start motor installations.. .

[@custos3249]

Interesting. Like watching the Nordic version of Abom

[@TDG2654]

Really cool video, very interesting to see

[@BentTreeFarmPa]

After you found the warp, you used a steady rest, did you true up the taper on the center while it was in the steady rest before you put it back on the live center? I am in the process of buy my first lathe, and trying to learn all I can. Thanks, I love this stuff, and your channel is so much fun, this makes it even better!!!

[@Beyondthepress]

Yep that was the idea on that step. If it's just bearing surface that has been repaired it doesn't usually bend much and you can but those really thin 0.02 mm etc. steel parts on between the live center and the piece to center it with out doing this step but 0.5mm is way too much for that

[@Shermingtan]

Doy you clean your coolant tank every year? Those tanks can culture bacteria really well and they get really nasty quickly. Great job and thanks for sharing your work and experience!

[@Beyondthepress]

It depends bit on the machine and how bad the thing smells :D we used to clean all machines about once a year but now days coolants are much better and you can go multiple years with out cleaning on some machines.

[@davidchristensen2970]

Well done.

[@t837qvhsdKJ]

love this even better than the pres videos :)

[@MarkTillotson]

Great repair work - did you need to rebalance that rotor after the repair work or is it good enough once machined to match the original bearing srufaces?

[@HydraulicPressChannel]

Mark Tillotson usually we dont balanve them and they run really smooth. Sometimes they dont run smoohtly and then we balance them but it's some thing like one out of 50

[@MarkTillotson]

You must be doing it right 98% of the time then! Nice :)

[@AlexKall]

So nice hearing about mm and not 15/54 inches!

[@williamsshane21]

Nice work

[@awesomefirebird69]

I mean, sure it's just a one part job so the speeds doesn't really matter. But with a HM endmill of the same size you could probably go for Vc=250 n=4900 ap=full depth ae=1mm fz=0.1 F=1960 Helix down and then program an easy dynamic mill cycle with Q-programming right at the machine.

[@skuula]

I love when stuff is repaired instead of tossed out .. but Im curious, why did the customer have it repaired, not replaced? As far as I know, induction motors are cheap and it's easy to find a replacement for almost every one..

[@cornfritterjones5349]

I really like these

[@63256325N]

Thanks for the video. Do you miss working at the shop in that way?

[@blackbeardcb4007]

I’m a machining apprentice and I program heidenhain Bridgeport’s with different controls but i have never seen anyone have that many tool calls at the beginning of a program, is there reason for this or is it just left over from old programs you haven’t deleted?
