Regluing a dust cap.

[Vincehoffman]

Hey Lads,

I lurk here and on Thomas' IB Forum on a regular basis and I've a dilemma which the rather knowledgable posters here seem qualified to answer.

I just dug out and fired up a pair of vintage mid-80's Meridian M30 active bookshelf speakers. They've been unused for a few years. Long story short, one of the mid-woofers buzzed on largish excursions. It turns out one of the plastic dust caps has come partially unglued from what appears to be a heavily doped woven cone. Suggestions as to what sort of glue is appropriate for tacking it back on would be highly appreciated.

Happy Trails!

If you can find it, use a glue called ethyl Cyanoacrylate ester, basicly super glue, but thicker, it has a activator that is sprayed on once it is applied and the glue will harden instantly, the place I got mine from was recone.com, but I looked at the site and they do not mention selling the supplies anymore, you may give them a call. They also use to have a black rubberized glue that stays flexible, which is another option for that plastic dust cap.

You can pick up CA type glue at a hobby shop that deals with RC aircraft, the accelerator is available there too. I'd suggest "slow-ZAP CA", used in a room with approx 70 percent RH (CA uses moisture in the air to stabilize it's curing process, IIRC.

Be wary, CA creates fumes when curing - and guess what the C in CA means.
It's actually not dangerous like cyanide is, but it does leave a white fume/powder residue, so be prepared to have a small white powdery substance that may/may not come off vary easy

I used THIS to attach a new dust cap to a 15" woofer. It doesn't look like anything fancy but it dries clear and has held up for a couple years now without a problem.
