Hi All, As it was related to me by John Omiatek (the head engineer
at Classic Player Pianos and now Storey & Clark Pianos), Classic Player
Pianos stopped using the Perflex pouch material when they went into
production of their player pianos. After much research and product
testing, Classic settled on a material called Tuftane. That is the
pouch material found in all of the Classic players. Also, some time
later, Classic entered into an agreement with Baldwin and Wurlitzer
to make player pianos under those trade names. All of these player
pianos used the same 'aluminum stack' design that is the 'trade mark'
of the 'modern' Universal and American player pianos.
To my knowledge, the only problem that Classic (and later Story and
Clark) ran into with the Tuftane pouches was getting them to stick
to the plastic ring. During the time I was selling and servicing units
with Tuftane pouches, I encountered perhaps two dozen pouch failures
(out of many thousands). I also installed these pouches in numerous
Universal and American players, and have yet to hear about one that
However, it should be stated here that I did rigorous testing of the
pouches before I installed them into a unit. I did this by stressing
them far beyond what they would ever experience under normal usage.
This was accomplished by shooting 90 psi of compressed air at the pouch
at a distance of one foot using a standard air compressor and a jet
sprayer (typically used for cleaning). They were further tested at 60"
of water vacuum once they had been installed, even though the vacuum
pump in the player never operated at over 30".
