Here's an
interesting shot through the case of the organ. The view is from the
Choir Division, the middle room is the Great Division, and the far room
is the Swell Division. Note the ladder at the end which is needed to
get in the case. |
|
Also from the Choir
Division side from the organ, this shows how the organ case is actually
in a couple sections. To the left are the three chambers (the Choir
Division expression shades are at left), and to the right is the
facade. The pipes in the middle are part of the Great Division. The
black tubes in the foreground are air lines for the pipes in the facade. |

Almost every piece
of wood is stamped with the organ opus number. These floor boards
remind us that we're looking at Austin Opus #2771. |

A pipe organ cannot function without air.
Along the same lines, a pipe organ cannot sound solid without adequate
air supply. This is not a problem with this instrument as no matter how
many ranks are selected the sound is solid. Here we see the blower for
this organ. |
|
The blower is a pretty simple electronic
device. Here we see that this is a 3 HP blower producing 10" of static
pressure. This figure is important in ensuring that the organ has
adequate power regardless of how many pipes are speaking at once. |

This is a regulator chest. It will expand and contract according to the needs of the organ. |
