My hand-cranked 20er (20 notes on the paper roll) organ is based on the John Smith "Senior 20" design.
It is built from scratch, mostly from wood. It has bellows to supply the air.
It is "keyless," and uses paper rolls to generate the music.
Discussions of the John
and building suggestions can be found on Mel
pages at www.buskerorgan.com
Mel Wright also runs a discussion group on
small organs which has even more organ building information. See
the Busker Organ
Forum This is the place to discuss anything about
Hand-Turned Organs, Busker Organs (Monkey Organs) and their
music. Other types of Mechanical Organ are also included.
The plans themselves may be ordered from the John Smith website.
