The central nervous
system of many styles of pipe organs is comprised of miles of wiring
plus hundreds or even thousands of small leather membranes roughly the
size of a silver dollar. These
membranes are responsible for making electrical contact, moving stop
knobs or tabs, and opening the valves under each pipe. This leather is paper-thin and, when new, is very strong and
flexible. As this leather ages, it becomes weak and brittle and develops holes or tears. When
this happens that membrane is rendered inoperable, resulting in dead notes, stuck notes, dead stops, and other problems. These membranes can be replaced with new electro-mechanical valves and stop actions. These new devices can be expected to work, trouble-free, for much longer than the original leather.
is also employed in the wind system of your instrument. It is much thicker and stronger than the thin membranes
described, but is still susceptible to the same problems. When the leather on the bellows and other areas of the wind
system gives way, the results can be much more noticeable. You may hear loud wind leaks, the organ's pitch and volume may
drop drastically, or the instrument may stop responding altogether. These problems are quick and affordable to repair. In
most cases, this leather also lasts about 50 years.
Moe Pipe Organ
Company can provide an individual quotation for the re-actioning or re-leathering of
your instrument. Upon
completion of this process, the instrument will perform like new without
all the dead notes, stuck notes, leaks, and other problems you may be
experiencing. Moe Pipe Organ Company offers a 10-year guarantee on this service although
an organ that has been re-actioned or re-leathered is expected to perform without trouble for many
years to come. Please contact us for more information regarding re-leathering.
