AMICA Reprint of Standard Pneumatic Manual
By John A. Tuttle

Hi All,  While the AMICA version of the Standard Action Manual was
nicely done, it should be noted that Standard had a number of different
exhauster assemblies and the AMICA reprint version only covers one of
those variations.

With regards to the problem that Charles is having, what would be most
helpful is knowing more about the exhauster assembly in his player
piano.  The inherent problem with connecting the control linkage in any
player piano is that you have to completely understand what is suppose
to happen when the Play/Reroll lever is shifted from Play to Reroll
"before" you can determine how things get connected.

If you're unaware of the fact that the cut-out valve must be fully
closed and the fast reroll port in the tempo control box must be fully
opened when the Play/Reroll lever is in the Reroll position, how can
you make sense of which rods get connected to each other?  And even if
you do luck out and connect the rods correctly, how do you go about
adjusting them so they actually work right?

This is clearly a case where having a picture of how the linkage is
connected in one particular assembly doesn't do much good unless it's
identical to the assembly in question.

My suggestion is that Charles help us to help him by supplying a
picture of his exhauster assembly.  Then we can explain how the linkage
must be connected and adjusted so that it works properly.
