- Welcome to my impossible screw.
It's a small project you can do in your home shop even if you don't have a milling machine or lathe. A hacksaw and a file will do.
It also makes a nice last minute present.
If you try this I recommend to try it first with a brass screw.
It's very important to deburr it carefully.
Otherwise it will be locked in both directions.
If you give this away I recommend to loctite a small second nut on so that the big nut cannot be moved away from the split point. It will drive anyone nuts who doesn't know the secret. - Věda a technologie
As a German, I find this acceptably hilarious within the standards of German Humour Directive 10794.456.9783. Now that we have all had a good laugh, it is time to return to work.
Yes yes very funny, now to gulag

Yeah and me as a german ...i must mute the Clip to watch it without his nasty accent.....
I tried to make one, but I had trouble threading my carrot.
try freezing it first.
@@saradeanna - screw that.
I didn't understand. I tried it with celery. Didn't work.
silly wabbit you holding it wong
Got my carrot caught in cieling fan
My great great grandfather once told me that he witnessed the titanic. He said that he advised everyone that the ship was going to sink. Everyone looked at him angry and in disbelieve. He continued to warn people in many occasions until they kicked his ass out of the theater.
Lol!!! 😂
Theatre......
Why would they look at him in disbelief? Everyone knew that ship sank in the movie, because it was a real ship that sank. What a terrible joke.
Quinn Wilkinson went hunting in his property one day. shot a buck right on the neck in which the buck kept running and jumped the fence into onto my property. I was sleeping under a tree minding my own business when Quinn got close to the fence and demanded the deer. I saw the deer just relaxing there. I shock my head and explained that the deer was on my property. Quinn got mad demanding the buck. I was like ok. How about a game. Who ever can take a kick to the nuts the best keeps the buck. Since the buck is on my side I go first. Quinn accepted the challenged. “Ok come on” Quinn said. I got ready like a punter for the Dallas cowboys. Kicked him right in the balls in which Quinn screamed in a delightful pain. “Aahhhhhhhhhhjhhhhhhhhhhhhhhhhhhhhhhhhhhh fuck ahhhhhhhhhhhhhhhhhhhhhhhh. When he felt a little better he said . “Ok my turn” in which I replied “ all this shit for a buck, keep it”.

Using the carrot to show how to make this was a perfect teaching method. Thanks for including the explanations.
I hope both of your comments are sarcastic
@@8bas4 My comment was sincere. It made a clear example of how this works.

So dumb I just laughed out loud. First time in a long time - thanks!
@@vinylsp - It's a fine line between dumb and funny sometimes... : D
I looked everywhere, and nobody sells threaded carrots.
Go to the hardware store. Ask for a carrot threader.
However make sure it is a red Handled right handed threader.

Rudolph has them all at this time of year
Just ask AvE how to make one yourself. In this video he's working with a softer material but the principle is the same.

turn it until it is round between centers and then thread
I was afraid you wouldn’t reveal the trick.
Me too!
Scared me too
You know what they say....
Screw till you nut and if you can bolt, you nailed it.
Did you guys noticed "will drive you nuts" like he is talking about screws and stuff
this is *realy clever*
You have a rare disease called "THE BIG GAY"
@@magemagician4757 Yes.You?
@@goblinsaltiness4429 I have a disease called "Small Gay"
@@magemagician4757 also named "autism"
Other than the fact, he's using a bolt, screws don't use nuts. Its very clever
That's deviously simple. Nice!
Please speak on more videos. You have a calming voice. Love your channel.
That's really cool. Also thanks for showing how. I will build one now.
Did you?
Nope I completely forgot.
You have brought back memories of a childhood many decades ago as I had one of those as a kid.
This guy has too much enthusiasm in his voice. (Reminds me of the very stern and stoic Germans I actually know personally.)
Using the carrot to demonstrate has got to be the best thing i've seen on CZcams latley.
Will this work with a Cucumber?
Somewhere in there is a joke about screwing a cucumber...
😂😂😂
Don't be stupid, it would only work with a Zucchini...
Lol
It will also work on the streets
When you presented the vegetable, I could clearly see the answer. Carrots ARE good for your eyes like mumma said!
Ye until kids take it literally and start poking their eyes with it and go blind, pretty ironic...

erg0centric clicked on this to give the same info. Very good my friend
Jonny hooks yeah me too I wasn't going to post a link but tell about false meaning
Quite to the contrary, rabbits eat plenty of carrots and they probably have one of the worst eye sights.They excel at seeing in the dark, but during the day time they are almost blind as they can assumably only see shadows. I found this out when we had a rabbit population explosion in my neighbourhood. The rabbits would be calm as anything during the day as long as they "Knew" you were touching them, but would jolt if you made sudden movements with your arm or body. At night however, if I approached them from any angle, or made any sudden movements, they were calm and peaceful. Just thought I would share that due to it being a bad myth
I knew the screw had to be in two pieces but imagined some additional locking mechanism in the middle between the two ends, never thought it was a simple grind & cut away, very clever, I wonder if there can be some application for it in the industry or maybe children toys or something.
Excellent, just excellent. Thanks for the share!
Is anyone else going to appreciate the double-pun in the title?
@Ed Jack will "drive" . Another term for screwing. You "nuts". its nuts. What do u not get
Nah just you smartypants
Simple and brilliant, thanks for sharing. Cheers Peter
Ingenious, now for more! John
I can actually use this in a few ideas I have, awesome, thanks.
The girl at the coffee stand is also an impossible screw. Now I know how she does it.
That’s a pretty neat trick man!! Good work!!
That was brilliant!
Thank you, that was intetesting and I will try to make one myself
Simply creative
Thanks for make me smile when u show the secret of this screw
I am impressed!
Really neat idea ! thanks
Absolutely brilliant.
You made my head spin (in a CW, not CCW) with this one! Thanks for sharing. Now to fine some nuts and bolts to make it!
I'm sorry your head is stuck to the right! I hope you didn't go all the way! Lol
This is very cool! I’m gonna make one tomorrow for my kid. He does magic performances and he would get a kick out of this prop. Thanks!! Very well-presented, by the way.
Well done, very educational video!
Pretty sneaky! I like it. :)
Awesome job
Excellent video. Ill make one thanks.
Awesome......have to do this!!!!
That Is Genius...! Thank You For Sharing...! Keep up the great work. Kind Regards Nicholas🧔🏽.
Oh, hours of fun messing with my friends and family now, thanks.
not bad.
good trick for holidays i think.
Your voice is soothing.
Very interesting, good work.
brilliant sir well done!!!!!!!!!
Genius dude!
*The wordplay in the title deserves an applaud..!!*
👏👏👏👏👏👏
Very clever!
Thanks. I made this, this weekend using a larger brass bolt and nut it's a lot of fun. To keep people from finding out the secret of how it works I put a drop of super glue on the bolt above and below the nut preventing the nut from being removed
I bet people will be thinking glue some how was magicked in there because of the bit of evidence! Lol
Awesome man i loved the outro with al the stirling engines +1 sub
excellent trick!
your not too stupid. you just have not learned how yet. Great trick and video. keep it up.
He was being humbled, letting you figure out the rest yourself.
Fascinating.
tht's great , very useful .. thanks
Beautiful simply beautiful
Love it!
Fantastic.
clever! Thanks!
Very cool.
The use of the carrot to demonstrate was very creative.
I made several of the last night to give as gifts, I did drill and tap a 4-40 hole and put a stop screw on both ends to prevent the nut from being unscrewed thus revealing how it works
Ok.....that was kinda cool.
...das muss ich nachbauen und ausprobieren - Danke für den Trick - . I have to rebuild and try - thanks for the trick -
Si
Next video : cut threads on a carrot with a lathe
Its possible. I did it and im just in high school. :P
Quite clever
I thought I was going to go nuts at first.
I said screw it & ate a carrot.
👍👍Good video, thanks for sharing.
Would this work without a thread, for a drum brake for example?
Seeing the knife's blade, I would say, that it got its unique appearance and sharpness, when you used it to make cuts to that impossible screw too. :)
I'm getting anxious watching this
Awesome informational educational video experience Y'alls
very clever
Impressive
very nice trick
You can drive your friends crazy with this
that would make a good prank / puzzle gift lock piece
I think the angle is less important than the offset. The offset required is determined by the gap between the bolt and the nut. The offset must be able to force the two parts apart by slightly more than the gap. The angle needs to be just big enough to allow the required rotation to accomplish that. So there is a minimum offset and corresponding minimum angle, determined by the diameters and the gap.
I think it would be possible to do it with ramps on each half. Turning one way, the ramp vertical faces push each other. Turing the other, the ramps force the halves apart, causing the threads to jam inside the bolt. But this would be much harder to make. That's what I thought was happening. Imagine a cut along a helical plate passing out from the center axis through a thread, making one revolution. Where the two ends of the cut overlap, another cut is made on a plane parallel with the axis from one thread to the other. The two pieces would separate cleanly. The amount of rotation to jam would depend on the tolerance of the threads and the pitch.
Clever. Cheers
excellent
I like the SCREWED over pun there lmaoooo
that is really cool, do you know if it is used on anything, seems like it should have lots of uses
very nice liked it
im wondering how much pressure it can take with 2 wrenches
Awesome. Subbed!
Clever!
Awesome
Gotta love a pun in the title.
Nuts... And bolts. See?
Genius!
Nice you have a great ability to share this we enjoyed this as our visit visit to your channel.
That title is brilliant
Thumbs up for the excellent pun in the title.
Brilliant
I instantly figured how it must work.
Someone walks in the room and 1:46 is just sitting on the screen.
nice
I don't thing the angle is the critical figure. I think the proximity to the center is what determines the clamping force, so you want to be as close to the center as you can be without actually having the cut go through dead center. At least, that's what makes sense in my head.
You got it 👏🏻👍
I think the angle is critical as the thread height is related to angle. Turns per inch. So n degrees = n/360 * thread pitch. You need to ensure that you raise the height of the screw enough to cause it to jam against the thread play (whatever that is). It’s probably a small angle but I’m sure it’s relevant.
@@userwl2850 i dunno what you guys are on about, but it simply misaligns the threads between the two halves of the bolt. Essentially the same concept as a jam-nut - taking two nuts and trying to screw them against each other.
I believe you are wrong. Think about if it was cut dead center. The screw would rotate about the natural center line of the fastener and not provide any outward force... just an axial offset since everything would remain concentric. Still, a very similar story if you are as close to center as possible. If the angle is off center significantly, then pivoting about that point will result in a non-concentric path taken by the screw threads and result in binding. Long story short, eccentricity is what is causing this to work, so cutting on center, or as you state, "as close to center as you can be" without cutting through dead center does not cause any eccentricity. Or at least not a noteworthy amount to make this work.
This is correct. Not an opinion either. To the non-believers: when you remove the 45 deg. slice, that removes 1/8 of the thread lead. It jams because after a 45 deg. turn, you are forcing a misligned thread. If anyone is familiar with how screws operate, they create mechanical advantages. I'll skip the details and say it would take much more friction to jam it concentrially than it would axially for that reason.
I was expecting a screw joining the two halves that has a higher pitch, therefore jams the threads lenght-wise
Nice trick :)
Merry Christmas
My wife... Now that's an impossible screw
I havent had carrots in a while and they sound good
That is too complicated for me to comprehend but the 🥕 helped a little .. Honestly!
IMHO this is pretty smart and certainly not stupid at all.
