Thank you to the many people who have sent me sound advice on how best
to move an upright piano. You folks are really great. I now plan to
spend a day unscrewing, bagging and marking parts, and photographing
the entire process. I'll also tape over moldings to keep them attached
during transport.
This Apollo is in remarkably good condition for having sat in two
inches water for three days. New veneer damage, for the most part,
was due to glued joints separating (there was a fair amount of old
veneer damage). All but a few of the detached decorative appliques
and molding are present and accounted for.
The worse water damage was, ironically, to the expanse of veneer on the
top: It appears water dripped there and seriously distorted the wood.
I'll can either salvage the top veneer to do the remaining repairs, or
find some miracle technique to restore this large, blonde figured maple
sheet.
The piano has a patent tag listing Sept 1919. The serial number is
9548, as I recall. Its mechanics were restored at some point: even
though the vacuum pipes on the tracker bar are metal (lead, yes?), the
remaining vacuum piping is clear polyvinyl. What is the earliest
likely date that clear poly would have been used?
The larger tubing was routed and supported by strips of white linen.
The bellows works under pedal, but leak. The air motor works fine, and
the roller mechanism is limber. Bass and treble soft mechanisms work.
I didn't have a roll handy, so the remainder of the mechanism is
untested. One key sticks, the notes are individually out of tune and
generally get sharp as one plays from bass to treble.
Once correspondent reported trouble with my email address. It's
entirely likely: the ISP that hosts the wiseworks.com domain uses
domain-based and IP-based spam-prevention techniques, and that broad
brush frequently paints the innocent.
