The Lauter Air Motor
By John A. Tuttle

Hi All,

Just a quick word about the Lauter air motor. Although I didn't know
Mr. Lauter personally :-), I know from his pianos that he was a very
meticulous man (unfortunately his son didn't share his enthusiasm for
perfection). I think he would roll in his grave if he could see some
of the techniques that have been used to rebuild his pouch air motor.

Lauter used 'regular' motor cloth on their motors for good reason.
Strength and long life. Using the same technique to rebuild the motor
is not that difficult.  The only real 'problem' is 'setting the pouch'.
This problem can easily be avoided by making a pouch setting tool. Other
than the little hole in the center of the pouch setting tool which allows
for the 'stem', the tool is identical to any pouch setter. The only other
thing that requires attention is the correct replacement of the stems.
They must go back where they came from.  Upon quick inspection, they all
look the same but they are not. The lower 'set' of stems are slightly
taller than the upper set and getting them out of order makes connecting
the lower stems a little more difficult.
