hello,
       I remember a while back a discussion on ivorys.i dont want to
start the ivory frenzie again but i cant seem to figure out were to get
related articles.I need a good solution to getting the yellow out of a
set of ivory keys,i must be careful they are the first set i ever seen
that has not one chip of hairline crack from a knabe grand! i have tryed
wood bleach in the past which helped somewhat.but now im looking for a
perfect job.  =20

Bleach on ivory is nearly useless.  To do the job right, the keys must =
be removed.  Use 220 grit wet dry sandpaper on a perfectly flat surface, =
hold the key and sand the ivories perfectly level.  Use a fore and aft =
motion, not a circular motion.  Then move to 400 grit wet and dry, sand =
level, and then to polishing compound on a felt wheel.  While you have =
the keys out, clean up the sides with steel wool and a single edge =
razor.  If you clean the ivories this way, they will be uniform in =
color, and most of the surface irregularity due to wear can be removed.  =
While you have the keys out, you might as well rebush them, they =
probably need it.  Replace the under-key felts, and level the keys.  =
Lots of work, but the keys will be beautiful.

I just finished a 6'5" Knabe B, and I'm working on another.  They're =
great pianos.
