Hi DIY!
My headphones of many years recently broke. My first response was to attempt to glue them back together with super glue (ethyl 2-cyanoacrylate) however that didn’t seem to hold. Not even a little bit.
I then did a bit of searching and found that Sony often use ABS plastic in headphone manufacture, so presumably these are ABS. I then read super glue should work okay on ABS, however there seemed to be no bonding happening at all.
Do any of you have any tips for the best kind of glue or epoxy to bond these plastic parts back together and get the music flowing again?
I plan on wrapping the joints in thread afterwards, for additional durability. But first I need to get them bonded.
General purpose tip for Gluing:
Isopropyl Alchohol in a spray mister will speed up Superglue bond time from minutes to seconds.
Mixing glues can be very useful. For example, I’ll use Epoxy for the hollow insides but a drop of Superglue where pieces fit together to hold the pieces together while the Epoxy cures overnight. UV glue is fantastic for that because it cures instantly. But a drop of Superglue with a spritz of alcohol works good too.
I didn’t think of mixing glues, nor have I heard of the alcohol spritzer thing - I might give it a go. Thanks!
Cyanoacrylate accelerator is not IPA. It’s a mix of acetone and amines. You are getting a weak effect from the water in the IPA.
I didn’t say it was accelerator but it works like accelerator. This is the solarpunk forum where you are supposed to recommend hacks.
