This is to give some background to what we are dealing with here and
support some of Bryan Cather's post.

When I first started doing player work I attended a class by Wurlitzer
where we were told not to play the "William Tell Overture" because it
played so many notes at once that the solenoids would trip the circuit
breaker, and after tripping 3 to 5 times the circuit breaker had to be
replaced.

On another occasion I had a chance in the early 1970s to tour the
Aeolian factory in Memphis, Tennessee.  I saw an assembler put hot
hide glue on the reservoir bellows leaf edges.  When he went to put on
the cloth it slipped and landed so the it was diagonal.  He just pulled
it off the glue and put it back on so the edges lined up.  This left a
glue strip running diagonally across the inside of the cloth.

Another assembler who was completing the wind motor took the bellows
that were glued to the valve board, laid them down on the bench with
the bellows up and proceeded to strike the hinge end of the bellows
leaf with a hammer.  I was told this was to break up the excess glue
in the hinge.

There were other things as well that were not good craftsmanship but
these two occasions stuck in my mind and have helped me explain to
myself what I have seen in these instruments.  I was told the Aeolian
line workers were paid on a piece rate.
