Attaching metal to metal

[CrazeUK]

Hey Guys
Not really a home DIY, but it is a DIY fix non the least.

I purchased some Jabra Bluetooth headphones for the stepdaughter.
Somehow one of the headphones came off the headband. Either they are not well built, or they got stood on.

Anyway.
I am wanting to fix them as the everything else is fine on them.
I believe they are made from an Aluminum or Zinc alloy.

I already tried to use Apoxy resin, although i am not sure i got the mixture exactly 50/50.

Does anyone know of a sure fire way of fixing them - Ideally without damaging the paint (via welding) etc.

This is what the other side join looks like:

I'd try again with the epoxy resin, the surface area is slight so a good glue overlap is needed.
Give the resin loads of time to cure! The mix isn't crucial but the setting time will be affected so best get it right.

Hey John.
Thanks for the response.
Do i need to squeeze the bits together, or just let them rest with each other?
Also is there anything i can do to prepare the surfaces?

My original plan was to drill a tiny hole through and put a small screw in.

The surfaces must be completely clean and grease free, and if you can clamp the join up so much the better. A rough surface is best.
I think you'd be going some to get a screw or peg in there!

Or some "sticks like 5hit" or grip fill (though this could be messy). I my experience, Epoxy resin is too solid, and therefore brittle and won't have any 'give'. the size of the speaker in relation to the size of the surface you are trying to bond means there is plenty of leverage available to break whatever bond you're trying to form.

Think you'll struggle with that, not enough area for a good bond as said above.

Can't get a mechanical fixing in either by the look of it?.

Take them back and say it fell off.

Or if you're any good with marking up, and have a pillar drill and tap set then you could drill and tap and insert a small grub screw with thread lock. You'd need to be able to withdraw that cable first of all though

Clean the glue off before returning them.

Hey All.
Thanks for the responses.

So Jabra decided to replace them.
I just feel it is such a shame to just chuck the old set. I would rather repair them (i hate the throw away generation weve become).


So i am still planning on the repair job. My only thing is how lol

 

[mattylad]

Drill and tap them as above.
