Vintage Greenback Magnet Cover glueing?

Postby Medronio on Mon Jul 31, 2017 1:15 pm

Because i did not find a forum for vintage greenbacks i post my question here, hope you don`t mind.

I bought 2 vintage Celestion Greenbacks from early 70s and one just lost its plastic magnet cover.
I wonder how to glue it back again. Can i use a typical glue for plastic, paper etc. to do this or will the magnet maybe get very hot and therefore a special glue is needed for this?

I too have a few old speakers in this state and would also be interested in learning what is recommended.

I clean the back and use Evo-stick, a rubbery contact adhesive that fills some gaps and does not work harden and get brittle. No problems so far. It also works for small cone rips and for spiders separating from the frame too.

Im a big fan of this stuff:

Can be used for various speaker repairs and tolexing. Its heat resistant so should be good for glueing a magnet cap. Very similar to evostick but brushes on thinner, and sets very strong. Its the best contact adhesive I have found and I've tried a good few of them.

Will either of the above allow the cap to be removed without destroying the cap in the event the speaker ever needs repairing?

If you wanted to do that, I would say just use a very small blob of glue. The glue I linked to is very strong, so if you lay it all over its going to be very difficult to get the cap off again.

+1 with only laying down few small dots/blobs of glue, that's the way they usually did it at the factory back then also.

I've got some of that too! (I think at BygoneTones recommendation) but I use it for recovering, as it is much thinner on application and gloops less than Evostick on the large flat areas of cabs.

I use hot glue, just like Celestion did originally.

If that's a concern, what about some foam double-sided tape?

Now that you mention it the original adhesive does look and feel like hot glue. Thanks for all the input guy's.
