The fa็ade pipes. The pipes on the left have
been sandblasted in preparation for
refinishing. The pipes on the right still
have their original gold paint. These pipes
will also be repaired and any dents will
be filled in.
A new chest cable part way through construction. Nylon coated
wire is used to for to keep the cable size small and the make
soldering and assembly much easier. The wire does not need to
be stripped prior to soldering as the nylon coating simply melts off.
A close up view of the nylon coated wire.
Nylon coated wire being soldered onto the connectors for the
solid state driver circuit board.
Interior view of one of the windchests of the organ with the
new chest cable installed. The white devices at the top of the
photo are the electro-magnetic valves which control the flow
of air to the pipes. At the bottom of the picture are four of the
plugs that connect the wiring to the solid state driver circuit board.

helping his dad J
Here is one of the two main windchests in this organ prior to
wiring. The chest shell is new contruction and the boards to
which the electro-magnetic valves are attached are original to
the organ. New chest shells were required for this organ in order
to make room for the new electro-magnetic valves which replace
a deteriorated electro-pneumatic chest action.
This is an ants eye view of one rank or valves looking down
the length of the windchest.
Here is the same windchest after being wired. All the wiring
and the solid state driver circuit boards are contained within the
windchest. This eliminates the need for a bulky cable running
through the organ chamber. The only connection to the windchest
is made with a CAT5 ethernet cable like you might connect to
Here are the solid state driver circuit boards installed in the
windchest. They utilize transistors and other solid state
electronic components to interpret the signals from the organ
console and open the appropriate valves.
Here is the existing console prior to disassembly. The organ was
built in 1924 by the M. P. Moller company of Hagerstown, MD.

Here are the fa็ade pipes in 3 stages of repair. The pipes on the left
have been sandblasted and the dents have been filled. The 3 pipes on
the right have been painted with 2 coats of gold metallic paint and 1 coat
of clear laquer. The three pipes to the left of the 3 completed pipes
have only one coat of gold on them.
Here are some more completed pipes ready to go back in the organ.
