November 2008 - The new pipe organ is installed
During the month of November, installation work continued on our new pipe organ at the Church on the Green. The electronics and wind supply system were installed and tested, and work began on tuning and voicing the pipes. Click on any image to view the slide show with descriptions of each image. For more photos of the organ installation process, click on the "Photo Albums" link above. To return to the Bloomfield Presbyterian Church on the Green homepage, use the "BPCOG Home" link.

The facade, almost complete. As impressive as it is, the facade with its exposed pipes represents less than ten percent of the organ. The rest, including most of the complicated parts, is behind the facade in three separate chambers, accessible through the door on the right. The new organ console with some of the electronics exposed. When a key or pedal is pressed, or a stop knob selected on the console, the action is translated into an electronic signal that is then sent via cable to the central chamber behind the exposed pipework of the facade. The main electronics panel in the central chamber, behind the facade. From here, signals go out to all the other parts of the organ. In addition to a control signal, each of the 2,869 pipes in our organ needs a supply of air in order to produce a sound. Shown here is the source of that air, the blower, with the front of the enclosing cabinet removed. The blower, with the cabinet front in place. From the blower, air is piped to boxes called reservoirs, which maintain a constant air pressure. From the reservoirs the air is piped to the windchests, long flat wooden boxes with holes in which the pipes rest. In the two side chambers the wind chests take up most of the space, so the reservoirs are located in the cramped space underneath. Another view of air pipes and a reservoir under the windchest. Yet another view of a reservoir and air pipes. Still another view. To facilitate getting around in the cramped chambers, a series of ladders and walkboards have been erected. The upper part of the same ladder shown in the previous slide. Note that the wind chest in the foreground does not yet have its pipes installed. A view of the other side chamber, showing air pipes, reservoir, and ladder to a walkboard between two windchests. Some of the larger pipes have been installed, but most holes remain empty. Note the control cables entering the wind chests. A view out into the sanctuary from behind the facade in the central chamber. The brackets in the frame will eventually hold pipes. The air supply for some of the exposed pipes in the central chamber (also known as the More reservoirs, windchests, and pipe racks. A view of the interior of the central chamber. Pipes in the central chamber. More pipes. After the wind and control systems are in place, each of the 2,869 pipes has to be individually tuned and More pipes.
