On the other side of a stout masonry
wall, a sleepy town slowly became part of a great Midwestern
city. US 40 –
known as the National Road or the Cumberland Road, became in
this area Washington Street, extending directly from
downtown Indianapolis.
Perhaps the little town was named Cumberland because
it was built on the first major highway constructed entirely
with federal funds, a highway that was begun in 1811 in
Cumberland, Massachusetts.
As this vital thoroughfare widened, it crept closer
and closer to the masonry wall that separated it from the
small organ.
Inside the church, things changed, too.
Young faces appeared, aged over the decades, and
passed from the scene.
The little organ participated in the important events
in their lives – baptisms, communions, confirmations,
weddings, and
funerals. With
martial music, it braced them for the stern duties of a
World War, and then celebrated victory and peace.
It sounded notes of meditation, celebration, and
grief. It
played countless Christmas carols and Easter Processionals.
When the organ was approaching middle
age, the church was given a fresh look inside.
The display pipes and case front were removed and
replaced with a more modern-looking lattice screen.
Its console (for some reason the organ could never
understand) was removed from the front of the church and
reinstalled in the balcony at the extreme back of the
sanctuary, a place from which the pipes were barely audible.
Even the church affiliation changed when
the German Evangelical Church united with other
denominations to form the United Church of Christ.
Still, the church’s German roots remained apparent in
the names of many of its members, the headstones in the
church graveyard, and even the cross-street on which it was
situated – German Church Road.
Inside the dark pipe chamber, the process
of aging took its toll.
Leather membranes deteriorated.
Water leaked in despite efforts to prevent it.
Dust and fallen plaster settled on pipes and
mechanisms.
Still, the old organ soldiered on.
Choked with dust, its already dusky voice grew
thicker and darker, and many of its pipes finally failed to
speak altogether.
But the church is a place of rebirth, and
in 2009, the organ at St. John Cumberland United Church of
Christ began a new life, serving worshippers with new
vitality and panache.
The
original organ at St. John was built in 1936 by the Kilgen
Organ Company of St. Louis.
Kilgen was a major builder of the early twentieth
century, and is perhaps best-known for its splendid organ
built in 1929 for St. Patrick’s Cathedral in New York City,
an instrument that remains a masterpiece of American organ
building.
At Cumberland, the Kilgen organ consisted
of twelve ranks of organ pipes (see original specification),
installed on two levels.
Typical of the work of Kilgen and many other builders
of the day, the organ had an abundance of unison sound, but
almost no ensemble.
The tone was generally dark and heavy, a problem made
worse by the fact that the installation trapped sound in the
chamber rather than projecting it.
Reynolds Associates had serviced this
organ for a number of years, nursing it along until a major
renovation project was possible.
Finally, in 2008, St. John was able to proceed, and a
contract was signed with our firm to renovate the organ.
As organ conservators, we were interested
in preserving significant tonal portions of the old organ.
This process served the needs of the congregation in
several ways.
Virtually every dollar ever spent on the 1936 organ was
preserved in the new instrument through the retention of
several sets of pipes that would have been very costly to
replace. The
history of the old organ – the marriage of sound with people
– was preserved.
And, in a society that has come to value recycling as
the “green” thing to do, preserving worthwhile elements of
an older organ makes sense.
Pipes produced from wood sawn from forests a century
ago, or minerals mined and refined in the days of our
ancestors can continue to speak to generations to come.
From the old Cumberland organ, we were
able to save several fine sets of Kilgen pipes.
These pipes were carefully removed and crated before
the demolition of the old organ.
They were taken to our shop in Marion, IN, where the
process of transformation began.
The first step was to thoroughly clean
away the decades of dirt, dust, and oxidation.
In the case of the wooden pipes this was done by
cleaning away the outer layer of the original lacquer
finish, and then applying a fresh coat to seal and preserve
the wood.
The process of cleaning the metal pipes
is called “chelation” (kē lā’ shun).
The pipes are submerged in a bath of a diluted
chemical similar to the Calgon many people use on washday.
This gently floats away dirt and oxidation from both
the outsides and the insides of the pipes.
After this process the pipes are washed and rinsed,
and then allowed to dry completely.
Following cleaning, the pipes are
burnished to shine like new, and evaluated for repairs.
After this they go
to the voicing studio.
Here, they are placed on a special windchest where their
sound can be adjusted for the new organ.
The process of voicing involves techniques that are
hundreds of years old.
The art of revoicing older work is perhaps more
difficult than voicing new pipes because it requires
understanding both the original sound of the pipes, and the
sound that is intended in the new organ.
While this process was underway,
additional new pipes for the organ were being constructed by
our pipemaker in the Czech Republic.
These new pipes are not generic.
Every aspect of their construction was planned with
the final sound of the new organ in mind, as well as
consideration of how they would blend with the revoiced
older pipes.
The final voicing of these new pipes also takes place in the
voicing studio at our shop in Marion.
Meanwhile, new windchests have been under
construction.
These chests, which hold the pipes and control the air flow
to each note, are custom designed for each organ using
computer aided design (CAD).
Our final plan drawings are then separated, and the
parts are made using the computer controlled cutting system
(CNC)in our shop.
Like
all our instruments, the major components of the Cumberland
organ, including windchests, reservoirs, expression system,
and structural parts, were made of Finland birch plywood.
Unlike the usual construction-grade plywoods found at
Lowes, Finland birch is made completely of thin, voidless
birch plys.
Birch is an abundant and continuously-renewable hardwood resource
that is prized for its consistency.
Its fine, dense grain makes it the material of choice for much of the
furniture that comes from the north countries of Scandinavia
and Russia.
Using this material allows us to control costs by doing most
of our cutting on the CNC system.
Because of the dimensional stability and great
strength of this material, our windchests are not subject to
many of the weather issues that can be a problem in other
kinds of chests.
The windchest has a tonal impact on the
pipes themselves, and here the CNC cutting system
and the birch plywood material offer a major advantage.
The table-top of the windchest is made up of the
toeboards, and it is upon these that the pipes stand.
Our toeboards are 2 1/2” thick.
Each pipe is isolated from its valve by a special
baffle channel.
This channel allows us to combine the speed, dependability,
and ease of service of electromagnetic valves with the easy,
unforced speech of pipes on a channeled chest.
The channels, valve holes, and toe holes are
custom-cut in each layer of a
toeboard.
The layers are then assembled and glued in our large
vacuum laminating press, which was designed and built by
David Reynolds for our shop.
This press can deliver a theoretical pressure of
2,000 pounds per square foot – 64,000 pounds over a 4’ x 8’
sheet of materal!
During this time, the congregation of St.
John was not idle.
The old organ chamber was completely remodeled.
Damaged plaster was removed and replaced with wood
walls protected from the elements by a vapor barrier.
The open arch through which the new organ would speak was
also remodeled, both for appearance, and to eliminate the
sound trap that had so restricted the sound of the old
organ.
Workers painted the chamber, improved the access
hatch, and provided new electrical outlets.
Early in the project, we discussed
replacing the dated-looking lattice in front of the organ
chamber with exposed pipes.
Actually, exposing some of the largest functioning
pipes made the chamber interior less cramped.
To contain costs, we were able to refinish some of
the large zinc pipes from the Kilgen organ, and to create a
layout that is visually harmonious with the church interior.
An interesting feature of the organ’s
visual appearance is the leaf lattice in the upper arch.
This lattice was designed in our shop and cut with
our CNC router system.
Each of the four panels required 7,788 inches of
linear cutting to complete the pattern!
Assembly in the church, which required
several weeks, was finally completed in the early summer of
2009. With the
final voicing and regulation of the organ – done in place at
the church – the new St. John Cumberland instrument is a
versatile and seamless blend of old and new, ready to
continue serving worshippers for many decades to come.

Here are some
interesting facts about the St. John Cumberland organ.
There are now sixteen ranks of
pipes in the new organ – 25% more than in the old.
Seven sets of pipes are new.
Nine of the original twelve
Kilgen ranks remain.
The new organ contains an even
1,000 organ pipes, compared with 786 in the old organ.
For space reasons, 24 bass
notes of the 16’ Gemshorn and the
bottom 12 notes of the 16’ Trumpet are produced using
special electronic tone generators.
The organ is controlled from a
two-manual console by means of a state-of-the-art system
that manages all the relay functions and can remember
hundreds of stop combinations.
The organ can play MIDI instruments,
can change keys at the press of a button, and can
even play back selections that the organist records
into the organ’s on-board memory. |
