Finaly did some DIYing again

Posted 10th January 2010 at 09:26 AM by wintermute

With the Silly season and general busier than normal work shedule (working a lot of weekend) I haven't made any progress on anything much at all lately.

Last week my Mother In Law put my 2 YO daughter in the bathroom basin. It was only attached with what looked like tile grout. It didn't hold... Today My Father in law assisted to glue it back in with some marine polyurethane adhesive/sealant . Hopefully it holds! This stuff was similar to the glue I had bought a while back to seal my 3 ways (see the leaks are stealing my bass blog entry) but hadn't got around to using yet. It seems perfect, it remains flexible, seals, sticks incredibly well apparently, and even claims to dampen sound and vibrations . As the tube was open, I pulled one of the Three ways out and basically sealed every interior joint. I then put a slight 45 degree chamfer on the back of the woofer cutout and glued in the front baffle (it has always only been screwed and didn't even have a gasket). Tomorrow I'll put the drivers back in, I'm hoping for an improvement! The Other thing I need to do with these is put in some bracing of some sort (would have been easier without gluing in the baffles but I decided I wanted to get the gluing job done).. They don't have any and really do need it. I'll probably get some 25mm dowel and put in a few in strategic places. I figure I might as well experiment with these as they are the same volume as the boxes I eventually want to build as replacements so I might as well get some idea as to how they can truly perform, rather than the rather less than optimal way they have been for the last 10 years or so!

    Heh...shouldn't lavatories be fastened to wall studs with lag screws or something? Seems like that would be required by building code.

    Oh well, Gorilla Glue to the rescue! I overhauled a pair of Acoustic Research AR-11s and I don't think the woofer seals were in the best of condition; I've got to find better sealing material, but I suspect polyurethane adhesive may be too permanent...

    Yes I was rather surprised that there weren't fastening screws. Just a plate with a screw would have been easy enough for them to have implemented.

    Yes I'd have to agree that polyurathane for sealing the woofers into the cabinet may be a bit too permanent I've got some sort of nasty sticky putty stuff that is a bit like blue tack. this ---> Speaker Sealant - 2mt Roll - Jaycar Electronics It's hard to work with though, in that it is hard to get a consistent thickness as it is quite thick and difficult to spread.
