    8' Hohl Flute Construction

    Hi all,

    I recently bpught a rank of Hohl flutes for my organ build and I noticed that all the pipes between open 4' and around 1' have a wooden dowel placed inside the pipe. You can see in the picture wht I mean.
    I was wondering if these dowels have any purpose for being inside a pipe?

    Victor,

    Does the dowel pierce the sides of the pipe, or are they just glued between the sides? You can also find some information about the construction at: www.organstops.org.

    You may be able to download a copy of Audsley's book Organ Stops and Their Artistic Registration, or his other book on the Organ of the 20th Century.

    I hope these links help.

    P.S. He has also published a 2-book series on The Art of Organ Building, but I don't know where to find those.
    Way too many organs to list, but I do have 4 Allens:
    • MOS-2 Model 505-B / ADC-4300-DK / ADC-5400 / ADC-6000 (Symphony)
    • Lowrey Heritage (DSO-1)
    • 9 Pump Organs, 1 Pipe Organ & 4 Pianos

    I have seen something like that in drawings of pipebuilding. It is then used to keep the sides of the pipe parallel when glueing. But I always assumed they were removed when finished.

    Better builders will spread the interior of the pipe at the center (Metal or wood) slightly during construction. This improves speech and promptness of tone.
    (I believe.)
