Hi everyone!  I am building a set of small scale wood open flue pipes
and I am interested in how to determine the location of "nodal holes"
to make the pipes sound the twelfth (third harmonic), the octave and
other pitches.

I am starting with the Wurlitzer Style 104 Melodie Flagolet shown in
Doyle Lane's book, Band Organ Pipe Scales.  When I complete this rank
I am going to place it in my A. Prinsen book organ.  Any help will be
appreciated.

Thank You
