Anatomy of a WurliTzer Theatre Pipe Organ
MANUAL CHEST - PRIMARY PNEUMATICS
The leather puched out ot the gasket for the bottom of the bottom
board, which is covered by the valve cover board, is the right
size to cut out the gaskets for the primary pneumatics!
The valve board gasket was punched with 7/8" holes, which leaves
a minimal amount of leather between the holes at 1" spacing, and
then the concentric punches at 3/4" and 1/4" cut out the
pneumatic gaskets from the first waste.
Have not found a use for the 1/4" waste punchings yet!
