This is the chassis of and old 416 8Z woofer from Altec Lansing . When
taking off the cone use a simple knife and add solvent to the glued
parts . Those parts are very difficult to get rid off, however if you
want a clean job you must take them
away .
If youre using a new recone kit and youre not sure about the spider and
voice coil original configuration , cut the spider around the landing
so you can compare whith the new cone
.
It is a very good idea to replace all screws and to separate the magnet
of the chassis . Metal can get corrosion so screws may be in very bad
shape . !! If this is the case and you cannot unscrew them I use
a simple Dremel tool to make the job .
Once you dissasemble the magnet have
a look betwwen the poles, debris accumulate over the years.
Little pieces of metal can be there , you
must
remove
them
before
installing
the
new voice coil !!!
Just cut a piece of masking tape and bend it the way I did . That way
you will clean both poles , make sure it is pressed until the bottom
.
Lets see what we got here !! Very
dirty poles . Use the tape until it
come out clean .
Ive always like the flavour of the ALNICO
magnets so its a nice idea to make them work again .
After removing all dirt
and sanding the chassis it is ready for paint, black is a good choice .
Ok , now they are ready to be reconed again . Always make sure you
cover the magnets poles while working !!
