“It does suck, because everybody kind of makes fun of the Cybertruck. To the outside person, it’s kind of weird, it’s ugly, whatever. Once you actually get in it, drive it, you realize it’s pretty frickin’ cool,” he says. “It’s kind of been sad, because I’ve been trying to prove to people that it’s a really awesome truck that’s not falling apart, and then mine starts to fall apart, so it’s just… Yeah, it’s kind of unfortunate and sad.”
Adhesives can be incredibly strong.
But never a weld.
MEK welds styrene. Cynocrylate forms a mechanical bond. MEK will be stronger in tension, cyno stronger in shear.
Good ole methyl ethyl ketone.
Dropped a rubber boot in a vat of it once to see what would happen.
No idea why, but it came out much larger/expanded.
Fun fact, you can shrink barbie doll heads in acetone.
I don’t even know the name of the adhesive they used. I do know that it was made by 3M and that it’s orange.
Well, OK. So maybe that adhesive is stronger than a weld on that particular plastic. Of course, if you’re talking about adhering a plastic to a metal you cannot weld it so Elmer’s would be “stronger than a weld”. But whatever’s going on it’s not adequate.
E: and actually welding plastic together typically isn’t that strong, a mechanical bond can easily be stronger than melting the plastic to weld it.
