Please do a video on the physics of that j arm that connects the opener rail to the door.. The shape of it and how it provides a bit of lift instead of just pulling straight back is all very interesting.
super video. Very dangerous, I like doing DIY, but not with that much force!! I'm glad you demoed this, and happy a professional is booked to replace my spring. Too bad they don't last more than 6-7 years. :(
"This video is sponsored by any hardware store except the one where I told the guy 'yeah I already measured it I know which one I need.'" I laughed. I'm sorry.
Would have liked to have seen the bar/spring turning, it's not obvious what causes the bar to turn. BTW, Is it safe to say that if you disengage the trolly, and you can't easily open the door manually, then you should check to see if the torsion-spring is broken?
thanks for your video. Clear explanation and just what I needed to understand how they work. Too advanced and risky for me to try myself though. I just needed the segment to 4:27. And your music is fine to me.
Hi Sir, thank you for explaining how the spring worked. I have a question: since the tension force of the spring is at its lowest level when the door is lifted, it would be safer and easier to move the spring out when the door is lifted. Is that correct theoretically? Thanks!
If i understand your question correctly, you are asserting the torsion spring should be easier and safer to remove and replace when the door is in the up position, while the spring is nearly unwound. Yes absolutely safer. Only problem is the spring is not accessible with the door open.
Good thing you noticed the spring had broken. We didn't and it wore out the bearing where the garage door motor bore against its housing. I was lucky to find the replacement parts I needed. Looking forward to more Cavendish videos. Good luck!
Thanks, Michael! The weather has been really inconsistent here lately, so I'm stuck waiting for the time being. Hopefully we'll get some nice, cool fall weather soon and I can get it done then ... my wife is not keen on leaving her car in the driveway once it starts snowing!
I never thought garage doors could be so interesting. I work in a lot of warehouses. Some of the door there are 20- 30 foot high. Those torsion springs must be incredibly strong.
@@mikem5475 I suppose that would depend on a lot of things. But there's a lot of weight there. I wouldn't be surprised if people have been killed. And a strangely large amount of potential energy stored there. Who knows what kind of chaos a broken one could do? I'm actually a trucker. Similarly, I remember hearing how no one should never try to open up the spring brake chamber that stops trucks and trailers. The air brakes on a truck are actually powered by springs. They're in this roughly cylindrical chamber that's maybe 10 inches long 8 inches wide. Something like that. But, you never know what kind of mechanic you end up with. You might end up with some old timer who just fixes stuff like he always has since the 30's or whatever. So we have to learn the things they can't do and opening one of them things up is a really big no no. So much so that they make a particular fuss about it and every trucker knows that you don't open a brake chamber and if you do it could very easily kill you.
@@PaulTheSkeptic trailer mechanic, they told us about the doors and the brake cans as soon as we started. Supposedly a guy got killed by the dropping door at my shop. You definitely can open and replace the diaphragm inside the cans, we had them, dusty on the shelf, so we never did it in my time. It takes common sense, something most people don't have nowadays. Think about struts on a car (spring outside of a shock absorber). Same deal. Needs a tool containing it, like a press, and keeping far away from the trajectory if things go wrong. With the workers comp and liability, I guess it makes more sense to replace the $100 brake can vs the $5 diaphragm
Excellent video. You spoke very well. There was not the slightest ambiguity. The caution at end was perfectly placed. I would have used a full face shield.
You cant change spring potential energy in to gravitational potential energy. You can, however, change spring potential energy in to gravitational motion.
Hello there, u have done a good job! But when one spring brakes, its better to change them both.. They have the same age, and u must loosen them anyway.. Just a tip!
I heard that advice at the time as well, and figured I knew better. I got about another 6 months out of the other spring before it snapped. Live and learn, I guess. At least I was better at it the second time!
But that’s actually safer. You leave the good, ie, the dangerous one alone. Just work on the broken one. Work twice, but each time it is safer. Does it make sense?
@@mrweisu You have to loosen both regardless. So no, it's not "Work twice but each time is safer" it's "work twice and each time it's just as dangerous"

Oh dude
... this is Gold! Hire a professional.
I'm not being hard on you...but I am that professional.... for your safety... hire a professional.
thats the fashon famous backround music :>

Great vid, cool dude. Thanks.
Perfect!
Where to buy the big spring? Home Depot only sells extension springs. Are they the same thing?
its eerie how perfect this video is for my situation right now. thank you. thank you thank you
How did u know it was the spring that was broken
very nice. Thank you In future videos is it possible to eliminate or sig. reduce background music(noice) please. regards
How many time turn new spring install?

I heard if those springs break, the door completely destroys itself falling down and kills anyone underneath

i li ke the music
i hear the music more then the u talking lol
I didn't know Steve buscemi's son was so smart!!!
im 5
Without music. Your video will be better.
