Pyrotechnics ... Was Ivory Keytops

[Isaac OLEG]

A hot  iron and a wet rag, or even a hot gun may work without too much
danger I guess.

But too much hotness and celluloid goes on fire for sure (that is an
element of Nobel power or dynamite if I recall correctly).

Once thought it was a good idea to use a sanding wheel on a Dremmel to
"waterfall" a set of really badly chipped keytops on an old Acrosonic.

Didn't actually set fire to the piano, but there was smoke and flame!

Odd that this should be mentioned in a post today as I am about to do
the
same thing today on an old Gulbransen. But this time I will take my
time and
use a hand-held file.

Boy Scout should carry old piano keys and a Dremmel in their
backpacks.

David Nereson said: "Some attempts were made in the past to simulate
an
ivory grain in plastic.  The most common was probably "Ivorine," which
has
striations (faint bluish lines, spaced about a millimeter apart)
running the
long way through the keytops -- it's kinda hokey and looks not at all
like
ivory..."

David, et al,
That is/was not "Ivorine"! That be Celluloid! The flammable, stinky
stuff,
used in the first part of the 20th Century. Ivorine is the good
plastic that
many of use replace keytops with. The name "Ivorine" was the trade
name used
by Tuners Supply and is essentially "Pyralin", which is an Industry
name for
a specific type of plastic. It is sold by Schaff. Many pianos, even
pre-1900
had Celluloid fronts with Ivory tops. The better quality stuff lasts
forever, and is the precursor of the Pyralin. K? Best Regards, Joe

Sorry.  I assumed that because I ordered "Ivorine" keytops once from
Tuners
Supply and got the ones with the blue lines.  Still have 'em in the
original
wrapper.  --D.N. Squares R I
