Windchests -- Organ pipes require accurately engineered wind systems to provide air for optimum musical results. The pipes are arranged on windchests, which have an intricate system of channels and valves that direct the proper amount of air into each pipe at just the right time, ultimately controlled by the organist at the console. The air supply is directed through a series of wind lines to bellows-like reservoirs that regulate pressure before reaching the windchests. Reuter uses both electro-pneumatic and slider chests in its organ designs. John Leach has worked at Reuter for 23 years and is in charge of the department that makes these components.  The chest department also produces the hand-made leather pouches and valves that are an integral part of the playing mechanism, as well as Reuter’s unique aluminum-clad ball-bearing swell shades.
