Sitting
in the bottom of the small organ chamber is the main wind chest for the
organ. The wind chest contains a reservoir of air for the pipes and
helps maintain constant air pressure at all times. The black and white
parts of the chest are the liners (the white is actually leather)
which keep it air tight. These
have to be replaced or "releathered" every 30-40 years, depending on
the use of the organ and the environment it resides in. |

Just
above the main wind chest is the wiring board for the organ. Careful
notation of what each wire is connected to helps make maintenance a
little easier. The wiring board lists the four ranks of the organ, much
simpler than the 20 or so tabs on the console. The 16' Bourdon is an
extension of the 8' Gedeckt and not a separate rank of pipes. |

The
entire organ is under expression meaning it sits behind shades which
open and close. The shades for this organ are a little different in
that they do not all open in the same direction. In addition, the
shades open in pairs rather than everything opening at the same time.
So if the organist has the Swell pedal pushed down half way, two of the
shades on each side will be open, and two will be closed. |

The
main wind
chest is surrounded by pipes on three sides, illustrating how the
builder was able to
cram everything in the small room. The pipes on the left are some of
the larger pipes of the 8' Gedeckt rank, extended down to 16' for the
Bourdon stop. On the right are the 8' Viola pipes. The green pipe
is a air supply pipe for the racks of pipes above the chest. The thick
black wire on the left with a red and white wire attached is the wire
from the console. |

Here's
a
closer look at the mouths of some of the bigger pipes. Note the
difference in construction between the Gedeckt pipes on the left, and
the speckled Viola pipes on the right. These Gedeckt pipes are actually
of the 16' Bourdon stop, another illustration of "borrowing". |

Between
the shades we can see some of the smallest pipes of the 8' Gedeckt
rank. Note the interesting texture detail in the metal pipes. |
