I have a customer with an Aeolian spinet player piano and I need to
remove the upper part so I can do some piano action repairs.  I could
not see how to raise the upper part in order to remove the keys to
make the repairs.  The tubing going from the tracker bar to the stacks
doesn't seem long enough to allow raising the tracker bar unit so I can
take the keys off the center (balance) rail.

What am I missing to allow piano action repairs?
