Hi,  I have made a 20-note street organ similar to the popular John
Smith version.  The organ is completely enclosed in 1/4" Plexiglas
so all the mechanical movements can be observed while it is playing.

A number of people have asked if I had plans so I have now completed
a very in-depth construction manual on how to build this organ.  The
construction manual is available for $9.99 in e-book form only (for
Kindle, iPad, iTouch, etc.) at

http://www.amazon.com/20-NOTE-STREET-ORGAN-ebook/dp/B007AEK0TA/ 

A package of 48 of the most detailed blueprints can be downloaded from
my daughter's web site.  There is a direct hyperlink in my e-book for
access to that site and the site is set up for email and PayPal instant
access to the prints.
