Hi All,  I believe the best book ever written about building any sort
of pneumatic device is Craig Brougher's "The Orchestrion Builder's
Manual and Pneumatics Handbook".  The 3-ring binder version is available
at  https://www.buysecure.com/playercare.reprints.html#craig 

For a complete explanation of the contents of the book, please go to

Musically,
