Anatomy of a WurliTzer Theatre Pipe Organ
Manual Chest.
The joints of the chest side walls to the end of a manual chest
are a potential problem source for leaks between adjoining ranks.
These joins are not always perfect so gaps may be present.
While the chest was the other side up as the inside of the chest was
being shellaced extra shellac was
run into these joins. In some cases the shellac ran out the other
side. Repeated coats caused the leaks to stop. The gaps were not large
enough to allow glue to be forced around all the corners. The shellac is liquid
enough to wick its way around the corners and will fill all the small
gaps. It will shrink as it dries but the next coat will have a smaller
gap to fill until it forms a complete seal.
The timber adjacent to the corners was left un-shellaced to enable a strip
of leather to be glued along the join.
