The 72 open strings of the Bass Canon
sound one octave below the Harmonic/Melodic Canon. Cris Forster
used the String Winder (pictured below) to make the strings for
this instrument because thin and highly flexible wound strings in
this frequency range are not available from commercial manufacturers.

The String Winder (above) was
designed and built to make wound strings for the Bass Canon.
However, the versatility and accuracy of this machine also
enables Cris to make custom wound strings of various lengths
and diameters for other musical instruments such as harps,
guitars, and pianos.
