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.
Nothing that interesting, just enough to gain a reputation as somebody who can do solid in-the-field temporary fixes when a real specialist isn’t available. One that comes to mind is a portable toilet that was delivered (clean and empty, thankfully) with a split in the side of the tank. Guessing they got a little too close to the trees on the way in and the driver wasn’t paid enough to care. There was another one in good condition so this wasn’t a critical issue but still an inconvenience.
Wasn’t too bad, I could just about span the full length from pinkie to thumb tip and there wasn’t any missing material. More than I’d trust glue or tape alone to hold for long though. Drilled a series of holes in parallel lines on either side of the split and stitched it shut with paracord before painting over it with a 2-part epoxy as a strong liquid barrier. Don’t remember what kind it was but it remained somewhat pliable when cured so I figured it wouldn’t turn brittle and crack. It held for the duration of the job and didn’t leak as far as anyone could tell (and if it had, the terrain would have made that obvious).
Not the most exciting story of heroism under pressure but I went from learning about a problem to finishing the fix in about 45 minutes with fading daylight.
