More pictures will be added as work progresses.  Be sure to check back often.


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 “ant’s 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.

the harness connects to the combination action circuit board and

operates the stops tabs and thumb pistons.

on the lower right is for controlling the various features of the new

electrical system.

at the bottom of the picture are awaiting an outlet to be plugged into.


This is the area directly behind the new stop tabs.

The new stop actions to which the tabs are

attached are in a line on the left.


View behind the control panel.  The square circuit board at top center

is the back of the control panel.  The large circuit board at bottom center

is the new combination memory system.


Re-installation is begun!

The casework is back, now for the fa็ade pipes.

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.
