I wouldn't put 'Wanton Destruction 40' anywhere near the
floppy drive (or
any other aprt of a classic computer). The stuff we get in
the UK
contains some quite long-chain waxy hydrocarbons whcih will
gum things up
after a short while.
I've never worked on a Lisa drive, but I've worked on
plenty of the Sony
full-heigfht 3.5" drives, singel and double head, in HP
units. They are
similar mechancially to the Lisa drive. Some of the odler
eject
mechansims will come totally apart (the levers are held on
with
E-circlips), which makes cleaning a lot easier. The later
ones are
riveted, so you can just rmeove the springs, soak the
assmebly in
solvent, then work the parts back and forth and wipe off
the old grease
as it appears. I find propan-2-ol (isporpanol) woeks
well? for this.
There are some photos in my flickr acocunt (tony_duell I
think, but
searching for HP9820 will find it) which show a Sony
double-head drive
stripdown. Your drive is similar.
