Wood Joining Magnet Driven Connectors

That's pretty cool. I guess it would work in aluminum too, if you went slowly.

What percentage do you really think will undo years later? It does seem unrealistic.

"OOOoh! Gosh! Wow!" Translation: Idiot expensive way of fastening. Wood dowels do the same at slightly lower cost...

Wood dowels doesn't do the same, they don't pull the pieces together

I don't think slowly works, it needs the hammering to transfer any torque

Okay, so fastener design is another area where your knowledge is lacking...

which is often of course.

At least with screws (with nice plugs), etc you have a pretty good chance of taking the wooden thingy apart - who is going to know how to take apart stuff made with those magnet driven screws twenty years from now when they want to repair a stair riser?

I see crowbars in their future...

Yes. With most fixings what they are can be seen, and a pile of extra force can be applied. I can't help thinking these ones are a product to sell to folk not particularly practical.

NT

"Will", as in able or "will" as in attempted?

I can imagine that any contamination in the joint could gum up the works. There can't be a lot of force there.

No, they don't do the same. Dowels make for pretty poor joinery, in fact.

able

If my experience is anything to go by a good 50% of goods made with them will never be able to get all those fixings undone, making them a bit useless. I'd expect to see them on some tv shopping channel.

That was my first worry. I've seen several types of mechanical gizmos for holding wooden bits together and letting go. Futons and such. Mostly I use screws.

These look pretty nice but expensive. The mortising tool needed to install them is $1400.

yeah, it depends how much the screw head is slowed down by the surrounding aluminium, no only does the aluminium slow the diffusion of the magnetic fields from the driver to he screw head, it also acts as a brake on the screw-head during the "hammer stroke".

Then it's for manufacturing, and disassemblability won't be a priority.
