my wife says you talk weird
Oddly, she and I never have much time for talking.
Buuuurrrrrrnnn!!!!
The esoteric jargon is the primary reason I have a lifetime prescription to this channel! The articulation ffs! This man deserves an Oscar!
@ Jim I'm glad I'm not the only one who watches these vidjeos in bed, i thought i was getting odd. Last night, she wanted to know does uncle bumblefuck actually know what he's talking about.
She thought your little chainsaw was cute anyway AvE...

Look at the nameplate? Dangerously close to reading the instructions. It's a slippery slope, my friend!
Nononono, nook at the lameplate!!!!
Following instructions is a severely underrated super power. You'd be amazed how many times i did something in a single go by simply following instructions.
Marcel LeMay its a joke
RUclips User, Yeah, i know it is. 😊
I once watched several of my friends bumble around for 10 or so minutes trying to figure out how to route a dryer's drum belt. Then instead of showing them how to do it (since I'd done it recently myself) I asked them, "why don't you pop open the control panel on top and look at the instructions?" They thought I was genius when they found said instructions were there and included a belt diagram. They got to do the dirty work and I still got to look smart. :)
The best thing about standardisation is there are so many to choose from.
All these standards are confusing. We should make another standard to improve on the other standards.
Uncle Bumblefuck, as a software engineer, that much-maligned sentiment has bankrolled my livelihood for entire years of my career at a time. #theprocessbepraised
too many standars: clipboard warriors measuring they dicks
I like a proper standard!
Greeting from Germany
no standard is perfect, until I make my own, which is never finished, because it's not yet perfect.
Speaking as an electrical engineer, you have provided a major public service here, unlike any in my memory, and I am 70.
Kudos and thank you.
never again will I underestimate the hydraulic power of bread.
Indeed!
James Wade Cant wait to try this Monday on pixie converter at work!
Ciabattas are good for unsiezing italian starter motors.
I thought he'd pull out the ol' greasy rag hack again. This fucking guy keeps throwing me these curveballs.
You damned experienced these sort of things. Very knowledgeable.
My electrician friend accidentally blew the power to the ice making factory.
Now they've gone into liquidation.
Did the administrator freeze the assets? :-D
My brother in law was working as a security guard at the ice factory. I asked him what the hell he was guarding there at 3am. He said he was protecting the recipe for ice. I'm almost certain he was joking, but he's from Alabama.
@Robert Slackware it does if the ice is resting on land. They also think water expands when it heats.
@Robert Slackware not ice, but snow on land, that's what causing sea level rise
Dewclaw!!!!!
Tuned in for the 3 phase and stayed for the Norse mythology
"you can piss more current than that" - AvE best sentence ever XD
People are really shocked when I tell ‘em I’m an amateur electrician.
The immense amount of dad in this joke almost makes me feel like I didn't have a fatherless childhood...
Dad joke of the year
Thats elechicken
I’m a degreed and licensed engineer and have been practicing for over 35 years and your practical approach and clear presentation of engineering principles is amazing. You should teach!!
Looks like your daughter went wild with the stickers
been shaving his knuckles
felixar90 hilarious
Palms, too.
i was looking for hello.kitty stickers
Those are good daddy stickers.
Bad daddys dont get those.
The breadth of knowledge this man holds in his head is absolutely astonishing to me. I want to find something he doesn't know more about than I do so I can get a little bit of my ego back. Love these videos!!
You just removed a bearing with bread. I've seen you do some amazing shit, but this takes the cake. Hundreds of hours of watching your videos justified.
I had to go out and do it as well! Priceless...
I swear I absorb more information from these videos than I do from any of my University mechanical/electrical engineering classes.
Which is probably a good thing since I swapped my major to engineering management
t17389z this video is telling me it was just uploaded and you made this comment a week ago. RUclips is confusing me
patreon first. there was a vij-ay-o a few weeks ago to explain it
Wade Fahnestock patreon gets a one week sneak peak.
I too was a mechanical engineering major, considering sports management lol. They say do what you love and you'll love what you do. If that involves other people, fuck that, people make you hate what you do.
Probably a good thing if you're not actually that keen doing actual engineering and don't want to hit a glass ceiling and never get a payrise
The ladies they thought it was dead
He said he could fix it with bread
With a hammer and punch
a creak and a crunch
Now it runs like a crack head
THIS DOES NOT MEET THE RHYME SCHEME OF THE LYMERIC AND THAT MAKES ME MAD.
How about “Now it runs like it were painted red,” what to fit the rhyme scheme and all?
Now it runs and they all went to bed..
I thought the same thing and it twood be better if he'd said, "Now it runs like a naked crack head" which doesn't change the meaning, meets the definition of crack head, and also meets the limerick syncope qualificationamathingy.
The analogy my prof. gave for power factor was helpful. Pour a beer, the reactive power is the foam, real power is the actual liquid, and both together is the apparent power. And as for removing bearings, bar soap works well if you don't have grease or bread.
AvE: Once in a while you no so smart. Raiding your wife's battery stash could have serious consequences. Next time you're on a road trip don't be surprised if she borrows the neighbor's organic choocher .
AvE has quality taste in comments.
Just get a concrete vibe no batteries need but I didn’t have to get the wife new fillings
On the other hand she may just take the Mastercard and go to the Harley store to purchase a Milwaukee vibrator. A kick start model for the hardcore aficionado.
need some paint mixed?
Zac Macpherson yo, nice car lol
Every time I see that work bench I have flashbacks to my tours of an old motor service shop I used to be a customer of. Only thing missing are cigarette burns on the edges,( from forgotten smokes- old school rules applied), and a thousand coffee cup rings. Oh, and that unique smell- burnt windings, tobacco, and the tears of a thousand patrons who learned the bitter truth about their motors....
Those were the days....
Good times. I relished the "we used to have ten guys working here, now it's just me and Cletus" *fires stringer of tobacco juice* chat...
Boy, the way Glen Miller Played
Songs that made the Hit Parade!
Guys like us, we had it made
Those were the days.
verdatum and you knew who you were then!
AvE, The motor shop I help manage has 9 mechanics, 3 motor winders, a fully equipped machine shop with 2 machinists. The shop has been in business since 1935 and still the same smell of burnt windings and cigarettes throughout the shop.
Austin Schwebel Hell, give me a name and location and I know where my next vacation is going to be near!!! They just don't operate shops with nudie calenders and a beer fridge anymore...
As a 51 year old child, I love that I learn something new every time I watch your vids. Thanks for all your consistency!
I remember me sitting in the electrical machinery course I - motors....he went on and on about motors...and i didn´t undersand a single thing...instead i went to a local used parts shop and got me a 100W induction motor and opened it and test the thing troughout...it helped me a lot about how these things works...about the same as you done here....experiments are fun.
Thanx for this one :)
🖐️ I'm the guy you were talking about that rebuilds and rewinds electric motors for a living.
I would like to know more about your work.
can someone build a winding out of silver wire for more power?
Post some instructions on brushless DC motors.
New vs old motors ? I wind motors also, not many new ones as they go straight in the scrap bin
i could not find 1 moteor guy in all of town for my vintage fan, and s&h is more dolls than its chooch worth
I've worked around/with induction motors most of my life. This has been a great learning vid. Companies always just replaced these things at first sign of wear, and never cared if dragged them home. I never knew enough to bother stockpiling them, as I was told they are not rebuildable.
...
Today is a new fooking day my friend.
Bring em fuckers home
"The mass of the ass depends on the angle of the dangle"
why couldn't you be any of my engineering teachers?
Colleges/Universities do not like simple/truth speak. If you were to teach them everything they need to know in one year the university couldn't get another 1-10 years more tuition out of the student.
There is tons of learning to get this dangerfield's 1word punches. Or an isp va dicevice
"I've never met a strong person with an easy past"
life before AvE: It's broken, throw it in the bin.
life after AvE: Garage full of tools and machines and i am building my own 20ton hydraulic press. just saying.
I have an enormous (like, 100kg+) Siemens 3 phase industrial motor (still with the plastic caps on the terminals) sitting in my garage and I have no idea what I'm going to do with it, but it only cost me $50.
Standards are awesome! That's why everyone has their own!
pushing that bearing out hydraulically using bread was new to me. Thanks for something useful.
Whenever I watch your videos and you become philosophical, and I see the little hints that you'd just spent time playing with your daughter, it reminds me of the stories I heard of my tool and die maker great-grandfather. Died far too early, with lungs full of cadmium and a heart full of cast iron and love.
When I am on my deathbed one of my wishes is this man sitting by me while I take my last breath. I can listen to this voice all day long. It is hard to explain. it is like It puts me in life and time blown by the wind.
Thank you for being who you are.
Man, I love the way you think. It's always interesting to hear how you see things and the way you connect different bits of information to each other.
I love the tidbits you share... Ya spend 40 years wrenchin' on BMWs and ya start to think you've got an encyclopedia between the ears. But no! There's always an addendum to write in the margins.
Thanks AvE!
My mother's philosophy was 180 degrees from "I'll always protect you."
Hers was "That hurt like hell, didn't it? Don't do that no more."
you rock dude!
I'm Canadian (55 years young) and you make me twist a nut in laughter sometimes.
100% better than a tv series, I can so relate!
Licensed (retired) Toyota technician, I think we might be related
Apprentice millwright in a food plant, really wish BCIT covered a bit more about the one industrial part we're all expected to rebuild with our eyes closed. Really enjoyed the electrical troubleshooting and bearing failure analysis.
Your explanation of power factor was excellent. Pixies have always confused the F out of me, but I've learned so much from you. Any chance you can do an explainer on multimeters for dummies? I'm sure there are plenty of boring RTR shill style vids on RUclips about it, but I need one in Uncle Bumblefuck style.
Jeff Calander I second that! Multimeters for dummies 101
I'm totally with you man. Notice me senpai, notice meet... Lol
That would be fucking awesome
Yes please.
I would love this too
Great explanation of Power Factor and 3 phase. Way better than the lessons I had 40 years ago in college.
Keep up the great work.
Easily one of the most educational videos AvE has ever produced. And that's saying a lot!
That moment AvE starts talking about Baldur. The guy who killed him was Höður.
A Dyson digital motor vacuum ad before my viewing? Spooky.
I haven’t read all of the comments in the “dooblidy doo” but all I can say is.... THANK YOU FOR YOUR CHANNELS! I GREATLY appreciate your teaching, but stick around for your comedic wit. Fantastic job sir!
Better explanation of PF than I got from my EE profs 40 years ago, but I could be forgetting something. Great video. Thanks
Excellent explanation. Some textbook authors might get mad, people will actually understand the material instead of reading 15 paragraphs on something that takes two sentences to explain.
If you cant explain a subject to a 10 year old and have them understand it you dont know the subject well enough.
Power factors and phase angles angry pixies all on at Saturday mornin with coffee this is life
You are the best distributor of laymen's terms ever. I watch a video of yours and understand shit I learned in school/on the job a millions times more clearly then I ever did before. Now that the sunshine has been clearly blown up your tail pipe... Thanks man great Video!
ANYONE who deals with indutrial machinery should watch this!! Beautifying work!
DP= drip proof sometimes manufacturers use ODP open drip proof. You'll also see TEFC = totally enclosed fan cooled. There's also a jp frame which is similar to a c face, but intended for pumps with a longer shaft to make room for a bronze sleeve and a mech seal. Other than that man, you pretty much covered the basics.
I like the little Chickadee stickers.
Over the last few vidjeos I could swear you time your videos with my Physics 2 class this semester. Keep it up!
You should do this more often love this type of video. Getting old junk and fixing it up.
2:13 - "she won't let you fly, but she might let you sing" eh?
M'lud I never wanted him to get in any trouble
Why'd he ever have to leave me?
Worm, your honor, let me take him home...
Crazy! toys in the attic, he is crazy.
Ave is wrong. Obviously there are some cool kids here. Good day fellow floyd fans.
So if you install american motor in european equipment, do you need to install pound-foot to newton-meter torque converter???
You could sell this one on your website, it would be a metal stick, with lb-ft input and Nm output.
I always play these videos on my TV, my mom was here once and said she didn't know what you were talking about but you had her cracking up anyway.
Very informative, AvE! Love the bread trick. Filed away for future application.
Huh! 20 years a heavy equipment mechanic, and I have never seen that bread trick.
The grease works, but very messy!
24:30
Its not the motor per se, that is inherrently Y or Delta.
It's how you hook it up- it's what confuckeration you put the leads in.
I loved your digression! Pixies to the people! I don't know where you went to school brother but you seem to have more intelligence than lots of engineers!/ trades combined. Keep up the good work
I love watching your videos, and have for years now. But I will say this was one of your better videos in a while. Funny, clear, informative, and touched on a lot of points without getting to rambling (don't get me wrong, I enjoy your rambling more than most). But this one hit home about why I started watching your channel in the first place. We need more wrench ready kids in the world, and you are just the yoda they need to make wrenching seem fun enough to forgo a 100k student loan in underwater basket weaving and make money making things work. Keep it up.
Using white bread as hydraulic fluid. My sides.
BuffaloWarrior7
Wish I would’ve known that tip before when messing around with those motors.
Play-Doh works wonders as well!
Dude, I wish I had heard this one sooner. Awesome tip.
Silly Putty works. ATF works. Crisco works. Flour probably works. Campbell's Chicken & Noodle soup works. Brute force always works... until it breaks....
I tell my better half that I listen to your shows so I know how to talk if we ever move to KAMSACK SASKATCHEWAN.
Thank you very much. Nice job introducing PF. Simply put but all the right points.
Such good stuff. I know this is a little drier than most of RUclips wants, but this is really awesome stuff. I love that you explain some of the math too. The lost me in physics class by using super abstract problem sets you couldn't imagine in real-life. THIS is where I needed to start.
7:07 Ahhh the mark of the all mighty Chickadee!!!
I wonder how many of your peeps understood the reference to trail cables on mining equipment like shovels and draglines. Nothing like a 25kV extension cord feeding a couple of thousand horsepower walking dragline to separate the the men from the millenials is there? Skooken great vidjeo.
"It's always generally" one of my favorite expressions.
So much love for this channel!
Thanks for showing this video! I've saved and restored many old motors. The Baldor are pretty well made, in my opinion. Even their small cheapie ones like you show here seem to last quite a while.
Here's an interesting motor you might like to see. It is made for a cotton gin, where there is a lot of flyings and lint in the air. Instead of keeping the lint OUT, they made the motor with all open, smooth air paths so that the lint will blow through it. The winding is encased in solid fiberglass resin so as to eliminate lint getting stuck in the end turns and creating problems. It almost looks like a wet-winding for a submersible motor, but not as thickly encased. This motor was made in the 1930's and was in a scrap pile. With one bearing replaced and one repacked - it is back in action. ruclips.net/video/grjomtYnzNA/видео.html
The best explanation of PF ever!!
Just started looking at induction and synchronous motors in my electronics module (automotive engineering 2nd year student). It was great to revise it and learn it visually with you. Thank you!
That's the second time in as many days I've seen that trick with the bread. Finnegan on the most recent episode of Roadkill did the same, but with a bar of soap.
Good morning friends, Who is ready to watch uncle bumblefuck poke the pixies?
As an electric motor reminder I have to say this was very fun to watch great info thanks
Thank you AVE! I've had one of these industrial 3 phase jobbies in my shed for years, and I've been too scared to lookup how to get it running. You just gave me a starting point to get into it.
Has the long-suffering cutting mat gone to live on a farm where it can play with all the other retired cutting mats?
Weird, I just watched a vid where Finnegan [ Motor Trend 'Roadkill' ] used soap to drive out a bronze bushing on the end of a gearbox lay shaft stuck in the end of the crank!!
Philip Rowney the power of hydraulics knows no limits when applied with no rules in a parking lot or northern B.C.
Philip Rowney that wouldn't happen with dove!
andrew kennedy Yeah Dove's no good as hydraulic fluid, too much air in it. On a side note, that's also why it floats.
I’m going to watch the rest of your videos... 😂😂😂😂 I need to learn about this stuff for a job. Thank you for making it interesting and funny. And the bread trick... amazing! 👏🏼👏🏼👏🏼
Between you and ElectroBOOM, I honestly learn so much. And have a good laugh while learnin' my noodle real good like.
Did you say anything important towards the end of the video? I passed out when you said interracial balls pressed up against the backside
Hey Mr. AvE, just a little note. When you calculated the apparent power you missed the square root of 3. So it's 480V*1A*square root of 3 = 831VA. Greetings from the standardised Germany :P
Actually 796 @ 460. Name plate states 460 not 480. Ifn you wantn to be splittn airs
Dan House :D I guess you are right. I stopped the video a couple of times to take a look at the name plate. Thought that a simple "the square root of 3 is missing" isn't that helpful.
Would that be because the windings are in delta configuration? (phase to phase rather than phase to ground such as wye?)
no its a wye motor, the formula he is talking about is P (Total Apparent Power)=I (Line) * V (Line) * 1.732 (root 3) (P=V*I*1.732)
which is (for low voltage) 208*2.1*1.732=756.5376 VA to be more precise.
the reason for root 3, is the line voltage (wye) or line current (delta) is root 3 higher than the phase value, and for phase power P=V*I, so you need to correct for the higher line value to find the total apparent power.
Tyler Dickson: In a wye (star, Y) configuration, the star (center) point is *not* connected to the grid (neutral/ground).
This classifies as an incredibly satisfying vijeo.
"we are using white bread as hydraulic fluid"
That's why I'm subscribed, quality and original content!
But you missed the discussion on using imaginary (aka complex) numbers used in calculating power factors! We need some complex differential equations to fully understand how these motors actually work! /s
Michael Steeves No we don't. aVe will clobber us with another future vijeo illustrating how to avoid being electrocuted.
stop talking...my professor had scared the sh*t out of me when he uses all these maxwell stuff, for explaining motors...
"I will always protect you but you can never grow up."
Love your vids buddy! Thx for all u do!
That bearing removal trick is profoundly brilliant.
20:48 that made me wince just a bit...
27:30 what are the odds...the guys on Motortrends Roadkill show just used that little technique except they used a bar of soap...
This method can bust the casting that supports the rear bearing, caution is the name of the game here.
just a bit? I was yelling at the screen like a damn fool.
The hammer is softer than the shaft so no mushroom. I learned that the hard way with a threaded shaft (pump impeller) and a steel hammer. A piece of wood works in pinch.
It's not so much mushrooming the end, It's driving the shaft through the back cover. Don't ask how I know that.
he instantly says dp, no idea what it means, but we all know he knows what it means.
bob rosco in the electric motor world DP stands for Drip Proof motor housing. This means the motor is resistance to water being dropped on it etc.. where as a TEFC motor is usually completely water tight and capable of being hosed without giving up the smoke..
Great bit of information. Also I work on the powerlines and would like to say I appreciate your accurate powerfoctor summary. Hard to do that.
Informative and entertaining. I like the bread trick. I've always used grease and a 5/8" shaft I modified with an O-ring groove (with o-ring installed).
Could you start off each video by letting us know what the source of discoloration is on your fingers or under your nails? Sort of a ‘todays color brought to you by ....transformer oil and graphite dust’
I was hoping for some AvECAD.

I gotta say, I love the stickers on your ✋. Your the best Dad.
Sometime in the past, some engineer had the idea to try and do this. Those insights are what makes life grand.
My megger has a hand crank.
If Rick from 'Rick and Morty' was a real person, he would be AvE.
I just learned more from this video than from 4 years of electrical engineering education. Thank you.
Thanks for your videos. Great info, fun to watch.
Whew! Dodged that one. I am only 29.
27 here. Only 3 more years till I have to go fend for myself! I'm scared...
The Vile Bargain is college loans.
Great stuff... as usual and even got a laugh or two out of it.
Here's a guy that knows his Norse mythology. Never cease to impress sir.
