You just took me back 30 years to a lesson my grandfather taught me, driving across the desert towards Burns, Oregon. He told me the story of reviewing plans with his boss. The boss asked, why did you put that valve in there? He couldn't remember the reason, and volunteered to work late to redraw the plans without, to save the cost of the "useless" valve. His boss refused the offer, saying "Bill, you're a good engineer, there's a reason for that valve, leave it". A year later, during commissioning, they found that the valve made it possible to replace a pump that died during initial bring up. Trust, verify, and live a culture of respect for both past decisions and future needs.
Yo! I used to live in burns!
The engine compartments of most modern cars could also benefit greatly from some forethought given to maintenance.
Truth!
Like putting a starter under the intake? SMDH
forethought is given to maintenance and repair,
how to make it as hard as possible
Automotive designers especially should be required to spend a few months working as mechanics on these cars poorly designed for future maintenance.
no, we obviously need to cram in more pointless sensors an plastic covers
Stuff like this is why I always recommend that engineers personally build what they design at least a few times. "What idiot designed this puzzle" hits home a lot harder if that idiot was you last month.
Be kind to the next guy, because the next guy could be you.
Engineers are often overruled by architects and are told where shit is going to be. Typical hierarchy in construction of a structure is Architectural, Structural, Mechanical, and lastly Electrical for who gets a say in how shit moves about and where it is placed. Nevermind what the contractors do when they actually build it.
And bean counters who demand a cheaper solution even though it doesn't work in the application. And other bean counters who push off preventative maintenance.
Been an engineer for 40+ years, and my youngest son is as well. I tell him of the cartoon over my workbench when I worked at a TV repair shop to pay for school. The cartoon had a man at a drafting board, and a co-worker looking over his shoulder... "You can't put the fuses there, people gould get to them. It's been my "little voice" for my entire career. Thanks for the profound video, forwarded to my son.
Holy shit dude! As a mechanic with a son who are 8 decided to be an engineer (mechanical) I've drilled into him ease of maintenance!!! Thank you!!
Next time I have to take the seats, center console, entire dashboard and HVAC box out of a Land Rover just to replace the blower motor, I’ll think of this video.
I had to partially disassemble a dash on a 2005 Range Rover Sport. No rhyme or reason to the design. Not to mention that ridiculously over engineered cup holder in the center console.I feel your pain brother!
That disclaimer is a work of art!
Thank you! :) I put an irrational amount of work into what is essentially a giant Easter egg. I'm glad you appreciate it. :)
If you like my writing and sense of humour, you should check out one of my books! Because everyone needs a copy of "Surviving Life With Your Gigantic Penis" on their desk just to make people wonder. amzn.to/32gu4By
This was probably the hydro plant that taught the engineers NOT to hide the bearings in a hell hole. Unfortunately management probably said it was too expensive to fix even though engineering already had the plans drawn up.
Funny thing is, high price to fix, but the amount of money they are paying for each time someone is going down there, that could have been avoided, is probably like 10 times or more than the cost to make modifications
I know I'm hitting this video 2 years late, but just the lost revenue of shutting down that generator every couple of weeks for the better part of a day, would most likely have paid for the fix several times over.
@@RNMSC True, but initial cost, maintenance cost, and operating costs are the very different things, often paid by different people, departments, or budgets. There is a never ending list of examples of “It would have been WAY cheaper in the long run if..” which almost always follow some variation of “We’re already over budget, just get it built as cheaply as possible.”
Every student in America should have to watch this video before they graduate. Wow. Thanks for the excellent field trip!
For anyone starting out, insist to your boss to go onsite or in the shop and make friends with the "doers". Your designs will be much better. Become the "problem solver" designer, it's fun.
And for this design, it seems you could retrofit some sort of die spring setup to keep the pressure on the blocks. At least your rafting expeditions would only be when the blocks are worn out and need replacement.
I have a crippling fear of pool drains, and I'm somehow mesmerized by your little field trip, your descent into madness. This is my new favorite channel.
Have you heard of the horrible accidents in "kiddie pools" where small children sit on an uncovered suction port and literally have a portion of their bowels sucked out thru their anus? Can you imagine the rage of the parents against the crappy maintenance company that did poor upkeep. I believe modern codes require at least two drains in parallel, to limit the strength of the suction.
@@chetmyers7041That and having the drains be gravity fed into a sump, where the pumps would be.
I'd be surprised if anyone with this branch of submechanophobia hadn't heard of that aspect of physics.
Wow, Chris! Just saw your video of 2 years ago. I started my engineering career 60 years ago at a coal fired power plant and can really appreciate the guy who has to go down and tighten those bolts every few months.
Well, till the advent of plastics and self lubricating UHMW nylon, there was no substitute for the Ironwood block, which still is used in a lot of applications. But the next set of bearing blocks likely will be made from something like Vesconite Hilube, machined as a block to replace that ironwood, and placed in the same holder, and will probably still need the same adjustment every so often to compensate for wear.
That disclaimer had me rolling.
I love this. I’m learning to do electrical engineering after 13 years as a commercial / industrial electrician. So true, and I feel like my time in the field gave me a good sense of what good design can look like.
I love that you're making the jump from one team to another. There is no substitute for lived field experience, and it's going to make you one hell of a good engineer! :) I'm proud of you!
@@Physicsduck awww thanks!!
You Sir are a genius! That Disclaimer was unintentionally hilarious.
Amen!
Give the fasteners gear teeth, make a dual rack wrench to turn it remotely with long steel poles on a crane. or similar.
I'm not sure, but I suspect that the various issues with that would reduce, or eliminate the feedback you get from leaving the wrench on top of the dog bones as you're leaving the hell hole... err, the tactile feedback of getting the bolts tightened that you get at the bolt.
Must feel special to be part of such history
Excellent message, very well done!
Thank you :) I'm glad you enjoyed it!
That looks like one of thousands of old “open flume” turbines that were installed back in the late 19th and early 20th Centuries. You give me an appreciation for power plant operators who had to run these primitive plants. Leffel, Newport News, Fitz, and S. Morgan Smith open flume turbines were used in water powered mills, foundries, and power plants.
I also like how the terminology often evolves or is interchangeable. “Log stop” versus “Head gate.” Log stops could also refer to the logs or beams used to raise or lower the mill pond or lake. A certain kind of Log stop was also called “Stanchion Type Flashboards.” These could be used on Spillways. (Barrows; Water Power Engineering; p 535; 1943.
You are teaching me so much about these old low head hydroelectric plants that I can’t get from books!
This is the kind of thing 99% of the people don’t ever think about when they use the outlet to plug in their vacuum cleaner or use the coffee maker.
- That there’s actual people, technology, materials, and a dozen other things behind the scenes bringing what has become not only a necessity, but if one really thinks about it, the luxury of having instantaneous electricity 24x7x365.
- It’s only been about 125 years since electricity has been available, compared to the former 49 previous centuries of the written history of mankind; That means mankind has only had electricity for 2% of the time.
Sometimes the issue is the engineer. Sometimes the issue is the installer. I can't count the number of times I've had a sputtering cussing rage fit because some installer used my design as a helpful suggestion instead of the plan they were to follow. "I had a hell of a time figuring that out" they say. "You didn't have to" I say. "I figured it out before you bought materials." And now I have to look at their ugly, scabbed together work while they're off on another job never having a second thought about the future mystery they caused because it was easier for them to do it wrong and come in under bid.
We live in Michigan also. Near a hydro plant south of Big Rapids. My wife’s parents live in Constantine MI near a hydro plant. We were fishing below the dam when the Hydro horn sounded that the gates were opening. The increase in flow of water pushed us down river for a short time. Winters are cold here in Michigan
Must be em at #3. Love how you don't care about a batter bearing Material that doesn't need adjusting. Just a dry place to do the task. Freaking awesome. Looks like fun, looking for an apprentice🤣
Crazy! Amazing content brother
I know this sounds crazy, but lots of engineers never use the things they design! A lot of times, they simply can't use what they build.
I've been involved with clean sheet designs for complicated systems (aircraft). With a system with a lot of new technology, the engineers can only guess at what maintenance will actually be required when its fielded. I've seen thousands of hours spent on diagnostic procedures for faults on a component that in practice, almost never fails. I've also seen the reverse: a component that fails at 100x the rate the engineers assumed, and no maintenance or diagnostic procedure exists for it. It's usually a procedure like the one in this video that makes up the difference until they figure out how to fix it in the next revision.
This is why I have an engineering degree, and I am just a “lowly” electrician. Work on the stuff in the field, then I can really engineer some shit that’s worth it. Every engineer should be required to work in their respective field for 10 years before they’re allowed to engineer
The EULA alone warrants my subscription.
I'm glad you enjoyed it. ;) Welcome to the weird!
I’ve been a designer in this kind of industry for over 20 years. And I wish I saw this video a long time ago. Sadly too late for me but very very good advice.
I'm thankful you got to finally see it, and I'm glad you appreciate the sentiment. :) Thank you for being here!
I hate to break it to you. An engineer is generally clueless when it comes to maintaining something. This is especially true for the fresh ones who have something to prove. I suppose one can only hope for some forethought.
Yeah, I'm not going down there. Hell, I'm afraid of pool drains...this would have my anxiety up so high that I'd probably pass out.
Well said Sir.
The problem with a click of a mouse. Or an engineered design. You or we make equipment that does not require service for 40 or 100 years. But when it does you must tuck your panties in to your blouse. Just get the ful down there. Get it fixed. And make it work again. Not just for the next week but the next 100 years!
I've seen the young engineers. Not only will it be harder to maintain, but it will need a lot more maintenance.
... "And to shut it down, you first click on the button marked START"
Can confirm, nobody in 2024 is designing for test or maintenance, especially car manufacturers or mass spectrometer control units
WELL SAID, CHRIS! :-)
Legend
I agree with @JeffRAllenCH about the grandfatherly lesson. My own grandfather (not just a jack of all trades but a master of most of 'em in my book) drilled the idea of "make it easier for the next guy" into my head all the years that I was growing up. It is a good credo to follow and the probability is pretty good that the proverbial next guy will be you.
Which power plants do you work at? We have 5 channel dam, and loud dam just up the road. Definitely amazing structures from a time when men were men.
Is that a maintenance access hatch on the backside of penstock can ? You can see it at the 3 min mark, you might be skinny enough to fit through it ! We have some long abandoned new American vertical turbines in metal penstocks. Access hatches not designed for 6'2 250 lb person.
Love it!
Seems like that horrible little boat is the worst part of this job along with the lack of a proper drysuit to wear.
Wish my previous boss would listen to that wisdom.
No I think we can just glue stuff together and throw it out when we're done.
Disclaimer is tl;dr. You should capitalize the word Internet when you are referring to Senator Steven’s’ network of tubes. Other internetworks are not worthy of capitalization lexically and sometimes financially.
Oh my God that's terrifying
someone said the people who design car seats should have to sit in them at work
I think that works right up until you tell them they have to sit in the baby seat that's designed for that car. Then they just act like babies....
Greaaaaatttt... I'll be a theoretical physicist
"casual sex implies the existence of ranked competitive sex".... ok then lmao
I dislike our engineers. I swear they design our aircraft’s equipment for access by children. “Hey, there’s 120 F hardline connectors on this box. Let’s put the connectors and cables on the back against the bulkhead just for laughs. We done have to ever maintain it.” The jerks! 😡
Excuse me, sir, but your disclaimers notice contains a number of errors, and you KNOW there are consequences for being wrong on the internet. Some phrases such as "For Office use only" are repeated, while others such as "Close cover before striking" seem to be missing entirely. Worst of all, there's a missing right-parenthesis in the section listing types of projectiles, which means all of us are STILL TRAPPED INSIDE THAT SENTENCE let us out it's hard to breathe in here.
Disclaimer so long I forgot what the video is about :D
But who is actually maintaining that? (The person in the video), is that an engineer too, or someone with another profession? Im generally interested in becoming an engineer, but also ocassionally tightening these bolts or such things seems fun too.
If you want to be the guy tightening the bolts, look at becoming a Millwright.
in first
this is a cool
Not It!
No audio?
Sorry but im a computer scientist
Having received a CompSci degree over 30 years ago, I'm reminded that the difference between calling oneself a computer programmer, and a software engineer, is that the latter is expected to prove the correctness of their software, while the latter is expected to put bugs into software. Personally I went into Networking, where being able to read what the sniffer collected was of more value than writing the software that put that garbage onto the network. I write software for my own use, and don't have to prove anything, just fix what I find isn't working as I expect.
despite the great length if the disclamer i read it all it was hilarious that is the 3 time i have been entertaned by the comedic prowes of some poor spitefull and bitter smuck who had to write one of those.
