This Oman pipe organ, which recently turned one hundred years old,
required a major restoration. Many pipes weren't
speaking, the main reservoir was suffering massive wind leaks,
and the original relay and contact system were failing rapidly
and totally beyond repair.
We were called in to evaluate the instrument and to propose
remedies to the organs problems. Without any doubt, the
best course of action was a total rebuild. It was decided that the
existing pneumatic chest action would not be long term cost
effective to rebuild. Instead, new Great and Swell
windchests were constructed incorporating the existing toe and
rackboards thus preserving much of the original chest woodwork
and keeping the costs lower. Electro-mechanical action
valves were installed replacing the original, leather
intensive pneumatic action. The biggest benefit of this
conversion is the elimination of the re-leathering expense of
the windchests in the future.
Wooden components of the Oman bell crank feeder
reservoir were in such a state of deterioration that the
reservoir was removed and replaced with a new single rise
reservoir as well as all associated ductwork between it and the
windchests. The original Pedalboard and ivory manual
keys were rebuilt and retained with the addition of modern key
contacts. A new solid state switching system and four
level combination action was installed.
The organ had never been modified tonally since being
installed by Oman, with the exception of an Oboe rank
addition by Mr. David Holtje in the 1980's. We
decided that the tonal scheme served the congregation well for many
years and that nothing should be altered from the original
tonal specification. However, to enhance flexibility,
inter and intra manual couplers, including Unison Off were
added.
This Oman pipe organ has reliably served this
congregation for many years past and with this full
restoration, will continue to serve future generations of the
church!
