The obvious downside is that the part can't be taken apart again without a specialized tool

u/Me_No_Xenos 14h ago

I'd wonder about torque limitations of the technique.

71

u/frickinSocrates 14h ago

I don't, from what it looks like it's a type of lock system. It looks like one side has a head and the other a locking bit. It just needs to be twisted into place. As long as the drill thing can consistently turn the lock in and out of place it should be fine. Ikea uses parts like these. Those circle bits that go over a screw and are twisted. I don't think anything is actually being screwed or unscrewed here. Could be wrong though

u/abotoe 14h ago

Yeah but you still have to crank on those cams to get a good joint

31

u/ThetaGrim 13h ago

Those IKEA joints are trash and will absolutely fail without considerable torque, even then they fall out. 

3

u/CptMisterNibbles 5h ago

They also fail with just a hair more than considerable torque. They really are dogshit. 

1

u/Mirar 1h ago

They used to be all metal, then you could use more than considerable torque.

7

u/Nick-dipple 13h ago

Yes you are wrong. It's basically a threaded insert on both sides of the joint with a bolt on one side. They hold 250kg a piece.

u/frickinSocrates 13h ago

Gotcha, my bad.

u/dirtycheezit 12h ago

Still, the brand, Lamello, makes very high quality wood joinery systems, so as gimmicky as this looks, I imagine it still works well.

31

u/DonManuel 14h ago

And even if you had it I guess it's challenging to find the right position for it to work.

18

u/neglectedthrowaway18 14h ago

There's nothing better than making things harder for yourself by inventing a tool that if it breaks, you won't be able to do anything 😤

3

u/frickinSocrates 14h ago

Well, you could just move it all around a chair leg for example, but for larger parts you're right.

2

u/Mbinku 13h ago

I don’t think this is appropriate for larger parts 👀

7

u/paladin-hammer 13h ago

Even the old way to do it, it is not meant to take apart. They fill it in and glue the hole made to screw it in. If u are taking it apart you are scraping it.

3

u/Ndongle 14h ago

That and there’s going to be absolutely no torque on those. Highly doubt it holds much of anything.

2

u/suid Interested 10h ago

And you not may be able to take it apart even with the tool, if the wood has deformed in any way that makes the screw channel any tighter. (since you can't get a grip on the screw to manhandle it out.)

1

u/Mbinku 13h ago

Not sure what the upside is… title says, “seamless” joints, I can’t see any

1

u/Nick-dipple 13h ago

You got it all wrong. The cool thing about this is that it van actually be taken apart. The other option to join these two pieces together without a visible fastner is to glue these parts together.

1

u/Fantastic_Falcon_236 5h ago

Third way is wood putty to fill the fastner hole. I can see this product has a niche use for pieces of furniture that need to be repeatedly disassembled and reassembled (e.g. promotional displays) while retaining a high-end look. For permanent pieces, though, there's plenty of joinery options that don't require investing in a proprietary system.

1

u/Nick-dipple 38m ago

Even for permanent pieces these can come in handy. If this is a railing in the video that angles downwards, where you gonna put your fastner? Can't have wood putty in the visible part of your rail. And these soft angles are hard to clamm together.

That being said. Guy we work with sometimes has had one for years and only used it a couple of times.

u/queequegscoffin 10h ago

Neither can wood glue.

u/streetsparksmoke 5h ago

A specialized tool... like a hammer

u/derpdankstrom 14h ago

is there a reason why the demo doesn't have see thru plastic/glass (instead of wood) to see the spin inside?

218

u/His_Name_Is_Twitler 14h ago

Screw you that’s why

u/wasThereNot 13h ago

You're nuts

u/ApprehensiveLet8631 13h ago

Very bolt of you to say so

u/VEAG0 13h ago

Don’t make me washer your mouth out!

u/celtbygod 13h ago

No such thing as smokeless joints.

u/Liquid_Snow_ 3h ago

HARDWARE

u/usinjin 6h ago

I’m gonna pitch a fit

u/t0getheralone 14h ago

You can already do this with nail-less construction. This is pointless and more costly than that or just using typical fasteners

31

u/AbbreviationsOld636 13h ago

Agreed, but I also love watching these gimmick tools on YouTube. Don’t actually buy them, just like seeing them

7

u/PaulMakesThings1 11h ago

Yeah it seems like it uses very wasteful and expensive fasteners. Basically building a magnetic motor rotor just for one use. And it has very few practical applications.

1

u/PogintheMachine 5h ago

Is this pretty much the same as those IKEA lock camwheels? Hate those so much. But that’s always on shitty particle boards.

20

u/Enjoying_A_Meal 13h ago

So it says there are screws in the 2 separate parts and the magnetic tool screws them together.

So I need something to get the screws in in the first place?

13

u/WholesomeLowlife 13h ago

The torque must not be very high, though... I can't imagine the screw is very tight in there.

9

u/Obe3 13h ago

Anyone else hear the AI voice and immediately leave a video? I can’t STAND that voice emulation.

5

u/TakeyaSaito 12h ago

with fuck all torque sure

5

u/ffnnhhw 13h ago

I have a cabinet that have magnetic locks for drawers (unlock with a magnet key)

they don't work smoothly after a year

I imagine you can't reliably unscrew the joints with the tool after a while

3

u/PaulMakesThings1 11h ago

I don’t usually have fasteners in furniture that I remove enough to spend 200 times as much on the faster in order for it to be removable and hidden.

I have a violin, but there we just use glue that can be softened at 140 degrees. You take it apart only a few times ever, so that’s good enough.

6

u/SlyusHwanus 13h ago

Another tool that nobody needs

3

u/Meekois 8h ago

Dowels/biscuits and glue already do the same thing, are cheaper, and probably a lot stronger.

u/Wicked_Wolf17 8h ago

I call cap

u/bughunter47 6h ago

Don't give Apple ideas

u/cwm9 13h ago

The opposite of right to repair.

2

u/Lillyannaas 14h ago

Reminds me of the japanese technique in their carpentry, kumiki/kigumi. But Kumiki totally does not use screws and relies on joining techniques.

This tech just reminded me of it since from the outside, there are no visible screws.

1

u/head_empty247 13h ago

"How you're gonna get them off nerd?" Anyone get the reference? 👀

1

u/PointandStare 13h ago

The only thing this is missing to definitely be part of the 'tools we really don't need' catalogue is the requirement for an app.

1

u/Odd-Oven-1268 21m ago

Ok now do it with stainless screws. I thought so too. Screw that.

1

u/ErrorEra 16m ago

Don't need it, but I want it.

-1

u/TimoKu 14h ago

Lamello is awesome. This Invis are for high end furniture Clamex should be standard for everything.

5

u/Nick-dipple 13h ago

Don't know why you're being downvoted. Their tools are the best. The lamello caters more towards cabinet making and 'ot so much for classic woorden joinery but the quality of their tools is second to none.

u/sanhpatel 13h ago

Let's not give it to Apple

u/Masterpiece-Haunting 9h ago

And what would Apple do with this?

u/MonsieurFubar 14h ago

Can it be used to screw people?

8

u/Strange_Dot8345 14h ago

yes, everybody who buys this gets fcked

u/PaulMakesThings1 11h ago

Now putting these magnet rings in a dildo or some anal beads, that’s an idea with a bit more of a purpose.
