61.jpg (19303 bytes) Here is the working end of an instrument under construction. I seem to recall that the keyboards themselves were purchased from a vendor but I'm not sure, at this late date, that I remember properly. The drawknobs are electric. They are actually switches which also have a solenoid which makes them go in and out depending on the setting of the combination piston.
65.jpg (18932 bytes) Here is the back end of the keyboard. You can see how the action from each key is transferred to an arm above. For short distances like this, aluminum rods are used.
69.jpg (16910 bytes) Here, we see how transmitting the motion over longer distances are implemented with thin wood strips ("trackers").
66.jpg (21543 bytes) These sets of levers are used where the action has to turn a corner to get around within the pipe chambers of large instruments. The yellow bins at the rear hold all the little pieces of hardware which go into the construction.
64.jpg (20285 bytes) A larger view of how the keyboard and pedal board action is translated into the larger scope of the instrument. They keyboards are below the center, straight part at the bottom of the picture. At the top of the picture you can see the first wind chest with some tapered metal pipes already installed.
67.jpg (16120 bytes) The long, thin strips of wood are being cut to the desired length.
68.jpg (19098 bytes) While modern materials like metal screws and plastic washers are used at the ends, the length of the tracker is made of wood. This is done to equalize any change in length that the wood parts of the organ may experience due to environmental changes in temperature and humidity.
