Anatomy of a WurliTzer Theatre Pipe Organ
Manual Chest.
Brass inserts hold the screws which hold the bottom boards to the
manual chests.
These are a common point of failure as can be seen at the top which
has pulled out of the chest.
To the left of the top insert the end of a small phosphar-bronze pin
can be seen. These pins are inserted into a groove in the side of the
brass insert to prevent the insert from unscrewing when the screw is
removed. This does not always work.
An insert which pulls from the wood or unscrews will cause damage to the
bottom board and probably enable a leak to the adjacent holes.
