thanks for sharing the scary video with us
I'm just wondering how old are you ?
@kahlid-ataya, I don't know how old he is, but when he was talking about all the "vintage" motors, I realized that I must be really old because I can remember when they were new.
THAT BEAR 😂😂 NOW YOU GOT TO WATCH OUT FOR THE BEARS NOW . NICE ONE MR CARLSON. NOW GET YOUR ARSE BACK TO WORK.
This was instantly one of my favorite videos. Some education, a good story, a bear, and hummingbirds. I would love to have you as a neighbor!
So would I, but he probably would not want me as his neighbor ;)
Yes, just make sure he keeps his fans to himself...
You're still here making videos sharing your experiences and making us wiser. Keep em' coming!
I know exactly how you feel Paul. Back when I was a teen, My oldest brother had just gotten out of the service. He did the stupid thing of taking an electric power drill, and attaching a circular saw blade to it. that blade spun to full speed and came out of the drill imbedding itself into the wall right next to me. I was at the other end of the garage, about 25 feet away. It was a moment that terrified me and I will never forget it. you recanting this story to us viewers woke that memory up and it flashed thought my thought like lightning!
That is terrifying but it made me laugh. I was the youngest of three and was often the guinea pig when they had some hairbrained idea to try out. Being shot with bb's and flying off the hood of a car were only two of my experiences.
@@curtisroberts9137 Yes sucks being the youngest sibling
Good God! I want the drill he used! XD
HELLO MR.BEAR :D
We don't get bears much, just coyotes, deer, and the occasional bobcat. And plenty of hummingbirds! I saw one eat a very small spider right off its web a couple of days ago. I was... _not_ expecting that, but there it was and, well, there it went!
I've never seen a motor shaft split with threads. Really odd. A good reminder about safety guards! Liked the wildlife shots!
Antique emerson fans had blades that threaded onto the rotor.
@@mattdavala3790 It was to extend the shaft for different models and a square key was supposed to be installed to keep them from coming apart.
Wow and I love the bear in the tree. It seems very happy munching your foliage. And the humming birds are amazing
You reminded me of when I was 19 (I'm 58 now) and working in a friend's basement with a box cutter on a project. I don't know how it happened because I was sure to cut down and away from myself, and I had no body parts near where I was cutting, but I still managed to slip somehow and slice into my left wrist right behind the joint towards the hand for about 3 inches. I cut through a big vein and several capillaries but luckily missed tendons. Unfortunately I was bleeding in spurts so bad and was in shock so quick I barely got to the top of the steps before I started to pass out. Fortunately my friend's brother and his mom were there and they got me to the hospital fast after some quick first aid. The wound required 14 stitches (4 internal, 10 external) and 1 pint of blood. I now have what looks like a small salamander for a scar on my wrist to remember that things can happen no matter how hard you try to avoid them.
Dang, I won't be using a box cutter in the foreseeable future
@@rogertoaster9385 I use a box cutter up to hundreds of times a day, high speed, for several years and have only dinged a finger tip a few times. I'm not recommending it, but I cut towards myself more than 50% of the time (usually opening small boxes). I hold the knife in a way that my arm or base of my wrist is first to hit my body, and never have my left hand downstream of the cut.
I've heard of a few nasty accidents using them, and I had a close call that left a slice through my jeans thigh area.
It may help that I use a safety box cutter (extra quick to pocket) but the blade is still out until I release the slide.
It's funny, typing about technique for such a basic tool, but with how common and necessary they are, like ladders, they're dangerous.
@@rogertoaster9385 Just be very, very, extra careful with them. I still to this day don't know how my wrist got in the way of that blade.
Being a small child (under 6) i attempted to disassemble a wire steered toy car with scissors. Made a gaping wound between my left hand thumb and index finger. Not much blood, looked white in inside. Decades after, 3cm scar reminds of the blunder.
Holy shit😲
I am a simple man, I saw a fan, I clicked immediately!
I think the short lesson is that the most dangerous risks you take are the risks you aren't even aware you are taking. If you don't fully understand the design theory and physical construction of something being worked on, you could be taking your life into your own hands by tampering with it. Anything involving electricity, chemistry or heavy / fast moving objects is not a suitable domain for real-life field validation of the Dunning-Krueger Effect. The average person understands far LESS about the average topic than they think.
I'm so glad that fan missed you. Talk about having a guardian angel.
Awesome as Always...Really enjoy this Thankyou..
That's one hungry black bear good footage yes sir
Ha! I have a friend living in the north Georgia mountains who gets backyard bears all the time! Two rules: leave them ALONE and NEVER feed them. Glad you didn't get brained by that fan, Mr. C. When I was a kid my father and I had unloaded the back of his old Ford pickup and were standing next to the front driver's side. The engine was just idling. Out of the blue something went BANG! and we didn't know what it was. I looked at the hood of the old truck and it had thrown one fan blade up and out completely through the hood not 2 feet from our heads. It left a razor sharp slot 8 inches long in the hood and we NEVER found the it. Lucky us. I think of metal fatigue sometimes while trying to sleep on airplanes...... Great little "slice of life" you shared! Glad you're ok and like I say, PREACH safety...it's a good thing to learn and practice. All the best from the Sweaty South. 73 JEFF
Thanks for sharing your story Jeff!
I’m a big fan of Mr. Carlson. Sometimes I enjoy the videos so much, I can bearly contain myself.
Working on a high powered fan conversion for my car, replacing the mechanical fan and clutch. Your tale is sobering. Ive taken extra care, while this fan is hardened plastic the blades are sickle shaped and sharp, would lop off a finger in an instant. Thanks for the story.
You are still young Mr Carlson and I am a big "Fan" of all your posts !
I love these stories. Keep 'em coming. I have a story for you. In my teens I was a passenger in a car. I was sitting in front passenger seat. No seatbelt. Really dumb. In a left turn we went off a 35 foot drop down towards sea while the car was tumbling around on it's voyage down the 35 foot drop. On it's way the roof on my side was pushed in one feet while in the same time the sentrifugal force of the roll pushed my upper body against the lap of the driver. The hit smashed my shoulder bad , but not critical and we landed on the wheels. If my movement had been restricted of any sort , my neck may have taken the hit with severe injuries. In this case the lack of seatbelts may have saved my life.
My father told me once that his brother had put a grinding stone on a vacuum cleaner motor!
My father did stop it and said to him that when this stone does come off, it flies through the roof! Thanks for your story.
Jeez! That'd be a rocket if it broke off!
Yeesh. Youre supposed to use a washing machine motor (likely only lapidarists will get that)
Yes, but we all did stupid things when were young 😀😀😀
Thank you.
I am 76 and still do idiot things. Less of them now.
I watch how to videos and safety videos. Eliminates much foolishness.
Thanks again.
Another dangerous type of fan is the metal "flex fans" which were used in some cars in the 1970s and 1980s. A mechanic I know is aware of another technician who perished when an engine was being revved by an assistant, and when he was leaning over the front of the car to reach something at the top of the engine, one of the flex fan blades separated from the hub and went through him. I have never leaned in the "path" of a fan blade of a running car engine since I learned of that fatality.
As the saying goes, "Sometimes you get the bear and sometimes the bear gets you"! Here's to guys who occupied our parents basements, our first labs and surviving uneducated mistakes. We would dump all our completed chemical experiments into old two liter bottles (the nice ones with black plastic bottoms) of which one of them my friend and I called the "stink bomb" as it ripened up. Later while I was away at camp it blew and I'm told was quite the scene! Paybacks for sending my befriended stray to a "farm in the country" perhaps... Armed with a copy of Electronics Made Simple and loads of discarded black and whites and AM tube sets, my survival was also a miracle.
Wild story! I would say the most serious close call I had was on the job sometime in the 80's soldering a component in to repair a circuit board. Suddenly I heard this POP! and the same instant, a solder blob appeared in the center of the right lens on my glasses. I can't even imagine the pain if that had hit my eye instead. Needless to say, since then, whether I wear glasses or not, I always wear eye protection when soldering.
Bump for rotation...I'll just show myself out... Really enjoy your videos Mr Carlson, they bring back many great and some rather scary times...I lived and learned.
Oh, I get the picture! Yikes! Thanks for sharing this one.
Your workshop is so spacious and well laid out. I'm very jealous.
Awesome story, I love the wildlife bit at the end.
I love these short shop-talk videos... 👍, I can't wait for the car story you talked about to get posted 🤠👌
simply more evidence that Mr Carlson has a guardian angel.
A fan and a bear! We have a black bear circulating in our neighborhood as well. I have not seen it, but neighbors have and it had made the newspapers and TV news. Good story BTW. Looking forward to the car story.
Really enjoying this little series. This kind of knowledge is invaluable. Of course most lessons are learned firsthand, but it's always good to be reminded of the little things we often overlook. My biggest lesson was a jack failing within a second of getting out from underneath a car and eventually losing a few friends to the same mistake.
Your guardian angel was working overtime.
Who would have expected a two-piece shaft on a motor? But almost everyone who started young and enjoyed constructing neat things has to have some good stories. Here's one of mine:
I built up a H.V plate voltage power supply for some project in senior high physics class (1964) from surplus components. The primary filter cap was one of those old multi-segment electrolytic cans rated at something like 40mfd@450v if I recall correctly. Input was to a C.T transformer into a full wave bridge (5U4). Me and a bunch of guys in the lab were gathered over this thing. It did look good, if I do say so myself. Just before powering it up for the first time, some little voice whispered that I should have everyone to stand away. I am still thankful that I did.
When I hit the power switch that thing hummed for about five seconds while the filaments in the 5U4 reached operating heat at which time the filter cap cannister exploded leaving the chassis at a very high velocity, sounding like somebody fired a short barrel 12 gauge. On the way up, it contacted a fluorescent tube light fixture with its old style metal egg-crate diffuser. Whereupon it neatly embedded itself on the diffuser fins slicing the can about half way thru. We actually spent some time looking all around the lab for the can until someone looked up.
I am quite sure that severe injuries would have resulted if some of us had remained looking down on it when it launched. No caps have been used since without being tested out of circuit and no first power runs are done at full input voltage. But there was that time when I became the unknowing bleeder resistance for a pair of 872s and their oil filled capacitor bank. The experience was electrifying.
Why we are not all dead is a pure act of providence.
Mr. C. Thanks for the story time. I am really enjoying these !.........Canonsburg, PA.
Glad your still with us!
Dang, you get bears in your yard?? I always thought you were in a residential area in BC like Abbotsford or Kelowna... I didn't expect there would be bears there without going into the mountain forests... another hazard for Mr. Carlson - bears!
Great you caught the hummingbird taking a break for a sweet drink.
Great video! Thanks for sharing, especially your backyard footage!! 🙂
I am really appreciating these saftey related stories. Real stories of accidents, near misses and the like really help to drive home the safety aspects that people seem to put off to one side way too often.
Thanks for taking the time to make these videos and share the stories to help us all appreciate the importance of being safe.
Years ago when I was doing a lot of automotive carburetor rebuilding, I used a lot of different chemicals. One night when I was still in my work uniform I stop by my parent's house. My dad sat down next to me and said if you ever get away from those chemicals you will have withdrawals. I never knew just how bad I smelled or how much I was being exposed to those chemicals till that day, but am still alive.
MEK and Benzene are the worst! Be careful!
@@MrCarlsonsLab yes, I have used them all. But most of this was back in the 80s. Five of my fellow technicians are now dead. All died from cancer. The oldest one was 45, am now 62 but still going so far. Still have the Trans Am? I owed and work on lots of these. I also toured the GM plant in Van Nuys, CA back in the 80s when they were building Firebirds and Camaros. Sad that it no longer exists. Yours I believe was built in the Canadian factory. Take care and have fun with your projects, Mike
I appreciate your repair tutorials as well as anecdotes such as this. Please keep it up.
I do have to question how many old Tek scopes any one person needs however... :)
Thanks, like the little change of pace for a kind of break.
Scary fan. Nice nature shot.
Oh man! What a story. I would keep the blade around also just to remind me of how fortunate i am to still be here. Great story and thanks for sharing it with us.
So the Tree Bears of Canada is more than just a legend.
Realy cool how the humingbids move so fast yet can stop with amazing precision, and move again, in the blink of an eye
Glad you're still with us Mr Carlson!! 73
Yikes
I can imagine the shock of that blade flying past your face.
Funny coincidence I also collected and tinkered with what are now antique fractional horsepower induction motors.
I had Westinghouse Canada, Tamper (which I still have), Leland Electric and CGE and others up to 5 hp.
I inherited one complete exhaust fan belonging to my great grandfather circa WWII which I ran with only the front exposed. Kept a long cord so going near it wasn't necessary.
I currently have one from England I plan to build a portable room exhaust out of (and it won't be finger accessible and its not open either).
I was warned by my dad about running open fans beyond little desk fans.
Glad you escaped!
Kept your guardian angel busy😊
Haven't been that close to a bear in many years.
Looking forward to the next episode!
Great story and happy to see that you are fully intact.
Really glad that fan episode didn't go anywhere near as badly as it could have. Reminded me of something that happened a long time ago. I was at my local pub late in the morning and the place had some fans mounted on the ceiling. They had blades about two to three feet long and about six inches wide attached to central hubs hanging from the ceiling. There were only three or four people in the place and one of the owners behind the bar. I was sitting at a window table not far from below one of them. The screws holding the blades on the hub must have shaken loose and one of the blades detached from the hub and flew within a foot of my head and hit the next table with quite a bit of damage to both the blade and the table. The look on the owner's face was priceless realizing how close that was to a catastrophic event. I got very lucky.
Really enjoy your 'crazy' experience stories!
I'm sure most of us here were doing crazy / risky experiments years ago (in the 1980s and 1990s for me), so we can relate!
Thinking back on changing out a condenser fan motor on my air conditioner, I now see how important it was to put the grille on to test the fan. I didn’t but from now on I will. Thanks for sharing your narrow misses!
Again, I love this segment and format because it teaches us who never experienced this, not to be daring. I recall working with my grandad on the antennas. He had a pivot system, and I was I charge of lowering the antennas,he was on the opposite side to give me an indication of how far we were from touch down. I learned so much from him re safety, and when I got my digit stuck in a moving chain and sprocket,I realized how stupid and neglectful I have become. Please keep the format,we can learn so much from you and others,not to repeat simple mistakes
Looking back, it's a miracle any of us survived the foolishments and derring-do of our adolescent years.
Geeze that was a close one Paul. Glad you're still here
Stuff like that happens with RC plane combustion engines, too. In most cases the prop is just fastened with a single nut on the threaded crankshaft .. if they aren't tuned correctly and backfire, this may be enough too loosen that nut and make them throw the prop off.
Happened to me once in my garden (I think I even have the video up of this) and while I found the prop, the (spinner) nut was nowhere to be found. Newer four stroke engines (and larger displacement two strokes) usually had a special counter nut, which has a slotted cone at the back which then clamps on the crankshaft, to prevent that.
With two-strokes there is another thing that can happen (didn't happen to me, but witnessed it once) .. they have an rotary intake valve which is integrated into the crankshaft, by the crankshaft being hollow and having a cutout in it. This means the crankshaft is only an open "C" shape there and therefore quite weak, it can (and does!) break there .. and then it comes out of the engine, ripping the front bearing out, too.
There is a reason why you are always supposed to stand behind the engine when tuning it ..
Also just remembers, many years ago some an guy told me about the motorcycle he owned in the 1950s, which at some point just randomly locked up. He suspected a seized up engine, but it wasn't that .. the end of the crankshaft, which has the generator and ignition system on it, was screwed into the main crankshaft. This wasn't documented, if you bought a new crankshaft you got it already assembled, it wasn't mentioned in the explosion drawings in the parts list and so one.
What happened was, it loosened up, screwed itself out a bit and then got stuck because the crankshaft suddenly became wider .. He, being a toolmaker by trade, either got a new crankshaft or reassembled and straightened the old one (it was bent after this), drilled a hole near the end through both parts, pushed a (hardened) pin in and ground it down to fit. Never again any problems with it.
This type of experiences are what took us to where we are today. We all need to experiment, at least in our youths, but hopefully for our entire lives. The ones who survived and told the stories scare the young ones into a little bit of sanity, yet then they tend to still add chapters to “the book of close calls”.
Paul kinda liked the 'close' haircut the fan blade gave him, and has stuck with that style to this day :) Thanks for sharing Paul. It was an unexpected pleasure to see the local wildlife at the end. Made for a very relaxing conclusion to the video.
Relaxing!!?? Those hummingbirds are reeeal dangerous 😅
Love these stories, keep em coming!!!
It's also a miracle that I'm still alive. When I was a toddler, some teenagers in our neighborhood kidnapped me and put me into a well at a building site not far from our home. They put the steel lid on it and (what I've heard many years later) put some sand and other stuff over it to cover it up. One of the older kids from our street was following that guys, watched them and went to his mom immediately to tell her what he just witnessed. If that boy wasn't there at that time, I was dead by the age of 3 after a couple of hours due to oxygen deficiency. Sad and unfair about this is that that older boy died at the age of 16 due to drugs and I'm almost 40 years now and I'm still around. After that, I've had many bad shocks that I did survived. In my late teens I fell asleep with a burning cigarette on my couch, it catches fire. Cycling on my bike to work during a storm and a big piece of a branch of wood broke of a tree and flew past my face and it slammed a dent into a steel fence. After all, I believe in guardian angels and destiny.
Thanks for sharing your story!
Ahh ... stories from Mr. C's past! more more!
Back in 1977 I did the same thing using a 1hp 3600 rpm motor. Thankfully it did not have a threaded extension on the shaft but my god did it move air! Fear of parts flying made me shut it down before anything left the chat lol. My dad yelled down the stairs (my shop was in one corner of the basement) what was that noise and vibration he felt shaking the house!
‼️ Wait, bear in the tree in your backyard!! Is that normal? Can’t be normal! Mind blowing. Thanks for the stories of you “exciting” youth. I think it must be the “right of passage” into adulthood. If you make, you earned it. 😊
No wonder you got so many FANS!!!
Maybe we need Mr Carlson’s other lab for Paul’s other interests :)
having single mother made for a very boring childhood as a boy... so many things i could've learned from a father, oh well. i suppose better now than never. cool bear!
Glad you're here with us! My most dangerous situations were unknown dangers created by others. You really gotta be overly cautious.
Working on machines of others, I've come across so many dangerous modifications. External power sources, modification of cams, contactors, and even ladder logic from sub par repairs. Half the time it was the customer themselves, but they'll send you in without telling you the stuff they "thought might help".
Anyway, I mostly stick to the software world nowadays, but your videos really take me back to working on CNC and industrial machines.
Isn't it always concerning we you hear a CNC owner talk about modifying the parameters or the ladder?! It's bad enough to see their wonderful wiring updates...
Great video. It would be interesting to see some photos of a younger Mr Carlson
Great collection Mr Carlson sir and nice video 😊
That's a classic story, I can't say I've ever done something like that. But I can say I've been involved in other wild disasters.
That's the longest I've ever seen a hummingbird at a feeder.
This should remind all of us how very fortunate we lived to see adulthood! I wouldn't dare relate any of my close calls as I get the shivers just thinking about some of them..
Great story and cautionary tale. You must be out west with that species of Hummer.
Good morning Paul! Really enjoying these stories that you're sharing with us. I'm finding we have more in common than I thought. First engine I started playing with was when I was 9 years old, was a three horsepower Tecumseh engine on my go-kart. It was after a 4-H course put on by my neighbor who owned and operated a small service station next door. Go-karts dirt bikes, you name it. I really think it's a great idea that you focus in on safety in each case and provide some insight. Great video!
Hey, Paul, thanks for sharing the scary stories! I know a lot of us were thinking you are either perfect or edit out the bloopers, 😄. You are correct - nothing is more important than safety. I'm surprised I still have all my digits looking back on some of my capers. As a friend of mine says, adrenalin is funny stuff. keep up the great videos & stay safe! Don't go poking the bear....🤭
I had a shop teacher tell a story about how when he was younger he tried building an airboat and was trying to use a metal 3 blade ceiling fan and attached it to an engine. While testing the setup (with no guard) revving the engine up and down, the fan flew apart and one of the pieces hit him and cut him open (luckily it missed any major arteries or veins).
That was his way of teaching safety in the shop.
My wood shop teacher kept a finger in a jar.
I can only imagine feeling the ice form in your veins as that sucker flew by. So fast that you're barely forming the "What the----" and it's already gone. Glad to see you're still around though ;-D
That bear is awesome!
Man! We are all so daring when we are young. The best thing to come out of your scary experience is that you LEARNED from it and from then on became much more aware of safety. That experience could have actually saved your life- in later years- from another lethal mistake that might have happened otherwise. So I guess, be thankful for it.
"Daring" .... 😂
Naive is the better word I think
I'd say stupid rather than daring and it certainly seems to be more of a young male thing.
When switching up fan blades and motors a very important spec to pay attention to is the rpm rating of the blade. After spending 50 years in the HVAC trade I have seen a lot of wrecks with fans. I have seen home owners install 800 rpm rated blades on 3600 rpm motors. Each blade will break off the hub and create three or four projectiles traveling at an extremely high rate of speed.
Yay, 20.25 times the rated tension on the blade base, on top of the higher bending forces due to torque loads sounds like fun!
Dang man, Glad you are still around to tell the story. Keep these stories coming cause they are awesome
If you're ever working on that fork truck: Do not raise the rack, stick your head under the rack - to loosen a hydraulic hose fitting for the hose that's holding the rack up...this happened to a tech from Yale Equipment Services. One of the best, comfortable, let slip his tired bravado.Popped like a cantaloupe.
I'm glad your still around to tell the story! Thank you for sharing more of your life.
I love stories from back before safety was invented.
Besides, those tidbits from your life are very much appreciated.
When the SHOP hits the FAN ??? Glad you still have all your original parts Paul. A somewhat similar event almost cost me some skin. I used to own a 66 Chevy "mid-engine " van which had a removable engine cover between the front seats. One time when my sister was riding with me, she sometimes would sit on the engine cover if I had another passenger in the right seat. On one drive, a blade from the motor cooling fan sheared off the shaft and sliced through the side of the metal engine cover, cutting some of the wiring harness and stalling the motor. Since the van came to a halt, I found the broken blade under my driver seat, leaving an eight inch long tear that could have easily caused severe bodily damage . Talk about a butt puckering close call. We try to be safe, but sometimes the FAN has other plans.
I love these safety talks with so many close calls in my own life.
Talking of spring lost a valve spring from a cylinder head of a car which went a couple of houses away past my head.
Very happy bear, hummingbird full of sugar water, what's not to like. And Mr. Carlson is still a head in life!
Spinning fans indoors and black bears outdoors, Mr C living on the edge🤣🤣🤣🤣
Electronics and Nature.... nothing better 😊
I can't wait for the next shop talk, thanks for your hard work Mr. Carlson 👍
Those moments when you check yourself for blood in case you haven't felt the injury yet.
Gives a whole new meaning to the term ‘Fan Club’ 😂😂
That's the wrong way to get a haircut! Thanks, Paul.
My great grandmother had an ancient desk fan (30's/40's) that had a metal blade and very open safety shroud. Was always told not to get my fingers anywhere near the blades while it was on. Many years later, got buzzed by a radio transformer on the HV side (120 V input / 12 V output) while holding the prongs and tapping a fresh 9 V battery to them. Learned not to do that again! Until high school at least... when I managed to get some study hall mates to hold the HV end (again 10X transformer) while tapping the LV side with a 9 V battery (~90 V output, moderate amperage) and them holding hands. Was an entertaining experience for all of us.
My mom got a temporary eye injury many years ago when she was around a table top fan. It was a three blade open fan, blades were of a soft plastic and one tore off unprovoked.
My uncle told a story about a thick grinding stone falling apart in 3 pieces and flying past him left and right.
I have stories myself! LOL! I too was VERY daring back in my young 'stupid' years! 🤣
excellent, more of 'Mr.Carlson Recollects'
"Paul, how's your dinner, dear?"
"I'm sorry hun did you say massive fan blade almost cut my head in half?"
My goodness what a great story. That could happen to just about anyone... And not much room for grace embedded within that type of error. 😬Mr. Carlson recieved such grace that day for sure.
When I was in my mid teens I had two kitchen exhaust fans. I decided to make a double window fan. I mounted them on a wood box, and tried to hook them up, and ended up with a good shock, because nothing was grounded. I’m fortunate that I didn’t seriously hurt myself. And yes, it was bare blades.
