speaker cone repair , what glue ?
Posted: Tue Oct 14, 2008 10:19 pm
i have several speakers i should be able to repair myself as they just have a little crack (or two) or hole on the cone but i don't really know what glue to use for that.
i contacted Ted Weber for that a few months ago and he didn't tell me what glue to buy nor where to buy some ( just said he couldn't ship adhesive anymore since 9/11) but gave me a few advices to do it although i'm not sure i undestood everything :
" push the tear back into the hole. spread soem white elmers around the hole. Lay down a small patch of tissue paper.Work it into the glue and smooth it out.
More glue
more paper
do that 5 times, smooth it all out, let it sit overnight.
Done.
do you mean i have to spread the glue with some thin cloth (not kleenex i suppose as it will dissolve in the glue ) around and on the tear untill it makes a very thin coat that dry up ?
Spread the glue around the hole with your finger.
Then lay down a patch of tissue and work it into the glue and smooth it out.
More glue, more paper. Do that 4 or 5 times and let it sit overnight.
a guy that repair speakers here told me to use Neopren glue (like bhostik) to repair paper cones, is it the same sort of glue as the white elmers you talk about ?
It must be a butyl or a thin glue. Otherwise, it won't soak into and bond with the paper cone. It will just lay on the cone. Neoprene will work as long as it isn't to viscous (thick) "
what i understood was that i have to use some thin (layered ) patches of tissues ( like kleenex ?) mixed with the glue .
do the layers one by one up to 5 times and let it dry all night .
but i'm surprised he says to mix tissue paper and glue (not just glue !) !
he says the glue has to dissolve partly in the cone but the patches of tissue paper won't dissolve in the cone, just make the cone thicker (especialy with teh glue) !
also, i checked on orange county speaker repair website for the glue to use for that type of cone repair but they seem to say that the white elmer is too hard / brittle whereas their glue (XL49) is pliable :
