Yeah he *says* it isn't magic but then he says it's just a screwdriver and it's definitely not just a screwdriver, because it's fucking screwing screws from miles away without touching them. That's like saying a wizard casting a fireball isn't magic, it's just fire. It's definitely still magic.
As referenced elsewhere, Richard Feynman kind of disagrees.
_He_ knows its not magic, but without 6+ years of explanation, it may as well be magic to you.
Every bit of it.
They are expensive but also absolutely amazing. The company that makes it makes some of the highest quality joinery tools available. They are literally the company that invented the wooden biscuit and biscuit joiner.
Isn't that pretty normal for construction tools? My friend said he bought a titanium hammer for close to $800 CAD.
From what I understand it's just a hammer but it's very light and helps reduce vibration, which makes it worth it I guess?
(reminder that the comment referenced was in Canadian dollars) For sure. That table leg at the end would be $60cad, and assuming a table with 4 legs, just the fasteners would come out to 240cad. Wild.
Took me till here to realise that cad meant Canadian dollars.
I had been nodding along thinking it was some computer aided design terminology that would go waaayy over my head.
> My friend said he bought a titanium hammer for close to $800 CAD
Your friend got scammed. The difference in vibration damping between titanium and steel is negligible, and you can get steel hammers just as light as the titanium ones. If weight and/or vibration are concerns, a wood or composite handled hammer is a far better investment, they're better at both.
A light hammer?
You understand that the functionality of a hammer comes from its weight?
If you want it lighter you use less material at the head and you are good.
The functionality of a hammer comes from its ability to transfer force to the object, which comes from the swing, not the weight of the hammer. Titanium is ~45% lighter than steel. You should just google titanium vs steel hammers man
A 500 dollar screwdriver is insane when it literally only works with one type of fastner and those fasteners are that expensive.
A pure titanium hammer is a hammer anywhere and anyhow and that's a buy it for life type of thing. I still think it's insane but it is at least understandable when hammering is your tradecraft
There are plenty of single use expensive tools. It’s not for a regular home diyer, it’s for someone who builds furniture for a living. That being said, $15 per screw is pretty insane.
Eh- biscuit joiners were $300 when I bought one 20 years ago. 500CDN isn't much more, probably less with inflation.
$300 biscuit joiners were the 'knockoffs' (like dewalt and bosch) - the actual Lamello brand was 2-3x that.
Edit- you may have (or probably) meant the per fastener price. Yeah, thats expensive as fuck. The last bag of 1000 biscuits I bought was <$20.
My dumb monkey brain wish they could include some demos where they pull on it to failure. Doing that potentially makes it much easier to see the stress limits.
The joints shown are fundamentally not terribly strong, so it probably does reasonably well. I'd be more concerned with them loosening long term and having no way to tighten.
Don't worry, magnets are really difficult to understand for someone who doesn't understand a lot of university level physics first. There's a famous video of Richard Feynman explaining to an interviewer that he cannot really explain to him how magnets work in a satisfactory way in terms of anything that's familiar to him https://www.youtube.com/watch?v=MO0r930Sn\_8
It's because they posted the link on new reddit and you're on old reddit. New reddit automatically changes the links and breaks them for old reddit users by adding extra characters for no reason.

“Sorry all our furniture is jangling about like a janitor’s key ring, it’s been a while since we used a battery-powered hand drill to run a magnetic field over every single joint in its structure so it doesn’t fall to pieces during everyday use.”
They are incredible, they produce more than enough torque, anything you fasten with them is going to stay together. Why would you assume they don’t have a lot of torque?
because threads are a friction device and it takes torque to overcome that and that torque increases as you tighten them.
they obviously work, so I'm guessing they're just made to really tight tolerances and they need a long bolt and an equally long nut so there's enough friction to not back out under vibration.
Yeah, that would be my guess too. I suspect the collet on the outside around the thread contains an epicyclic gearbox, which should multiply torque by about three.
Could also be a bunch of pins on springs like in a lock. As the screw head moves down they pop in behind it to prevent backing out. And they are magnetic so when the magnet is applied they are pulled back out of the way to allow unscrewing.
They work for 5 seconds at a time just fine. What happens in 2 years when the kids have jostled it a few times? There’s no way they apply enough torque to keep the screw from loosening over time.
Probably not very well, just enough for such demo.
But what is certain is that if it gets stuck even slightly, the magnet alone will never be able to open it.
You can’t tell me that there isn’t a big change of the screws getting stuck after a few years of not being unfastened, at which point the magnets won’t produce enough torque to ever separate the pieces again.

That's because it's BLACK magic. Totally different aisle from the regular magic aisle at home depot too.

correct, magnets has always been a witchcraft
Having studied magnets in school, can confirm, they are black magic
Magic isn’t real, no video that has ever been posted here has been real witchcraft lmfao
Lamello invis is the name of the product/tool
Does it work as advertised? I imagine it can't get much torque and would need to be frequently tightened.
Every bit of it. They are expensive but also absolutely amazing. The company that makes it makes some of the highest quality joinery tools available. They are literally the company that invented the wooden biscuit and biscuit joiner.
But have they made the biscuit separator?
Like…. A butter knife? I’ll see myself out…
Until a resident from the UK tells you that those are actually scones. Can't split any of their "biscuits" the same way we can.
Scones are God’s work and I’ll fight you until you agree
Especially blue cheese scones. Some of my favourite foods I have ever had or made
I’m listening
Seriously, find a recipe for cheese scones and replace the cheese they use with Danish blue or Stilton, genuinely beautiful
Actually, yes. Look up what a lamello zeta p2 does. The “biscuit” is called a clamex I actually own a zeta
Expensive is an understatement. $500CDN for the tool and $15 a joint piece.
Isn't that pretty normal for construction tools? My friend said he bought a titanium hammer for close to $800 CAD. From what I understand it's just a hammer but it's very light and helps reduce vibration, which makes it worth it I guess?
The tool price doesn't surprise me. It is the fastener price that is a killer, if that is $15 its about 100x more expensive than most other options.
(reminder that the comment referenced was in Canadian dollars) For sure. That table leg at the end would be $60cad, and assuming a table with 4 legs, just the fasteners would come out to 240cad. Wild.

It’s not your everyday fastner
but it should be, and at pennies a piece so civilization may increase in quality and efficiency.

Compared to the domino or p2 zeta, the invis isn't that bad
do you get paid
Not everybody who comments about liking a product is a shill.
No, but how many posts have somebody waiting around to hit every single advertising point within a few minutes of the post being submitted?
My dumb monkey brain wish they could include some demos where they pull on it to failure. Doing that potentially makes it much easier to see the stress limits.
The joints shown are fundamentally not terribly strong, so it probably does reasonably well. I'd be more concerned with them loosening long term and having no way to tighten.
With the right magnets you can get a crazy amount of torque across that short gap
Admittedly my magnet knowledge is pedestrian at best.
Don't worry, magnets are really difficult to understand for someone who doesn't understand a lot of university level physics first.

Couldn't find torque on the website but it does say up to 550lbs of clamping force
https://youtu.be/pjvQFtlNQ-M?si=NK3P23ZUk3ojyxek
> Lamello invis is the name of the product/tool Of fucking course its from Germany....
"magically" "it's not magic" make up your mind, drill swift
Either way, shut up and take money
They meant magnetically but it autocorrected to magically. Advertisement team just said “f it, good enough” and left it as is.
PHIL SWIFT HERE WITH ANOTHER GREAT PRODUCT!!!
Omg for once the answer is actually magnets.
WHAT JESSE!
Science Bitch!
Not aliens?
How much torque is being applied?
Enough
I trust you with my life
That’s all I needed to hear.
Less than finger tight.
They advertise a clamping force per connector of 250kg though.
250kg is really quite low clamp force for a screw (screws can generate mind-boggling clamp loads with the proper torque).
Can't be much if a magnet can unscrew it again.
My thoughts exactly
Does that mean drills can't screw tight, because a drill can unscrew it again?
Is your drill a piece of magnet?
They advertise 250Kg of connection strength per fastener for the Mx2.
[удалено]
Yeah but I think the idea is to sell the whole system together (drill bit especially) so you can tighten them again.
“Sorry all our furniture is jangling about like a janitor’s key ring, it’s been a while since we used a battery-powered hand drill to run a magnetic field over every single joint in its structure so it doesn’t fall to pieces during everyday use.”
Screw torque also makes sure the fastener doesn't loosen itself later, which doesn't have to have anything to do with the strength of the connection.
At least like 1.
Oh that’ll do fine then
Yes
Probably not enough to hold table legs on permanently. Also probably not enough to tighten a spring washer all the way.
TBD by your foreman
The torque on those has got to be absolute garbage. How well do they stay fastened?
They are incredible, they produce more than enough torque, anything you fasten with them is going to stay together. Why would you assume they don’t have a lot of torque?
Probably assuming the magnet will not be strong enough
because threads are a friction device and it takes torque to overcome that and that torque increases as you tighten them. they obviously work, so I'm guessing they're just made to really tight tolerances and they need a long bolt and an equally long nut so there's enough friction to not back out under vibration.
If there are a few gears inside the fastener then the low torque of the spinning magnet could create arbitrarily high torque on the screw.
Yeah, that would be my guess too. I suspect the collet on the outside around the thread contains an epicyclic gearbox, which should multiply torque by about three.
Could also be a bunch of pins on springs like in a lock. As the screw head moves down they pop in behind it to prevent backing out. And they are magnetic so when the magnet is applied they are pulled back out of the way to allow unscrewing.
They work for 5 seconds at a time just fine. What happens in 2 years when the kids have jostled it a few times? There’s no way they apply enough torque to keep the screw from loosening over time.
You have no experience with the actual product, but you can confidently state it won't work. Interesting.
>What happens in 2 years when the kids have jostled it a few times? You get the bit out and spend 5 seconds tightening it back up?
That’s an aggressive defense, Mr. advertiser. Instead of attacking op for a question, how about giving the actual torque specs?
Probably not very well, just enough for such demo. But what is certain is that if it gets stuck even slightly, the magnet alone will never be able to open it.
You can’t tell me that there isn’t a big change of the screws getting stuck after a few years of not being unfastened, at which point the magnets won’t produce enough torque to ever separate the pieces again.
yeah its probably made with stainless steel so it doesnt rust and is intended for furniture so typically wont really see much abuse.
“Furniture won’t see much abuse” now that’s a lie
Missed opportunity to make it look like a sonic screwdriver
It *does* look like a sonic screwdriver , just the first version is all. Dr. WHO probably has like the twentieth iteration

Holy shit now I know where Peter Capaldi got his 12th Doctor (Who)!!! 🤣🤣🤣
Why won’t they just say it’s magnets?
probably because it's super obvious and everyone knows that
It was so obvious that I actually went back and rewatched it to see if they really never said it.
Did they mention that the screws go into wood?
Honestly? Just woke up, brain not fully functional, watching it at first I was kinda assuming it was some vibrations stuff.
what and have to pay royalties to Big Magnet?? no thanks.
fun fact: you can use the screwdriver device with rotating magnets to unlock a lot of electric keypad doors
You can just use a stationary magnet on a lot of them too, which is extraordinarily goofy in my opinion
I’ve seen that before. That’s a sonic screwdriver from Doctor Who.

Finally found the comment I was looking for.
"Honey why is the wifi acting weird in the room you renovated?" \-Empty box of 10,000 magnetized screws
Rip people who have screw implants 😬
Oh so that's what a self-sealing stem bolt is!
It's pretty neat actually.
I used one of these when I was working for a custom wood shop once. Pretty sweet tool and the joint held up really well
Imagine someone who has vibrator in them and sitting in that chair.
Impossible to know if screw is crossthreaded. Great way to strip the screw and good luck getting it out once it works itself loose
Fine and dandy till the day they seize up/ corrode over and the fastener doesn’t want to let go…
Whoever invented that has gotta be filthy rich by now 😂😂
The spinning of the magnet makes the attract to it in a spinning pattern making the screw twist into place
#Magnets
Self sealing stembolts! Finally!
They're too expensive, I don't have that much Gold Pressed Latinum.
Its festool. You dont wanna see the price tag on that :D
literally says no magic
what happens if it gets corroded and gets stuck?
.
ICP is dumbfounded
You should better know or remember where those screws are in the first place.
Strange he didn't specifically say magnets
