Damp Chasers and the like.....

[Tom Robinson]

I've noticed that most old uprights abound with cracks and crevices
which surely promote air circulation through the case.  Player pianos
offer even more opportunity for air infiltration.  Merely adding a stick
heater probably increases the air flow due to the creation of a draft
(the chimney effect).  Is it possible, that sealing those cracks, and
even placing felt at contact points between removeable parts, if done
sensibly, could allow better humidity control, especially during times
of wild swings in room RH?  What are your thoughts on this?
