Paul,

what exactly is that cold cracking test and who is supposed to perform it,
the manufacturer or a tech in the field?

I heard a story years ago about a shipment of pianos from Korea.  A whole
container of pianos arrived with cracks all over the finish, and the buyer
refused delivery.  There is a test called a "cold cracking test" which was
apparently not done properly on those pianos.  The mix of polyester has to
be done properly, otherwise that batch of pianos may have finish cracking.
As far as the cracks on the plate and other lacquered areas, it seems that
extreme dryness and temperature shock has caused the problem.  It is
surprising that the moving company would not have had this experience
before, moving a piano during severe February weather.  I'm sure you'll get
a lot of guys on here who live in cold country who can tell you what went
wrong.  Here in San Diego, snow and extreme cold only happen when you want
it to (drive to the mountains).

First, I'd check with the technician that serviced the pianos in Alaska.

I usually just sit back and read everyone’s postings, but now I need your
help.  An insurance company has beckoned me to figure out what has caused
the damage to 2 pianos that were moved from Alaska to Washington in
February.  The owner claims these pianos were in perfect condition before
the move.  They were loaded by actual piano movers onto a moving van.  Both
have Dampp- Chaser units on them.  In my short tenure (8 years) of being
around pianos, I have never run across this situation before and could use
some help in figuring out what might have caused the damage.  Could a
combination of extreme cold and a 5-day move have caused this?

As a side note, the owner also has a Suzuki digital grand (Costco) that
sustained no damage at all on the case (unfortunately).  

Hopefully, the pictures are good enough to see some of the damage. 

Piano #1 -  Young Chang grand, model G-208, serial # G 104337, built in
1996.
The piano had 3 long cracks in the polyester finish on the lid, extending
the entire width of the lid.  The cracks are located on the front, middle
and rear of the lid.  The plate of this piano has hundreds of small cracks
in the finish, located throughout the entire plate.

Piano #2 - K. Kawai grand, model KG-5, serial # 479922, built in 1970 (but
looks newer – and I didn’t think Kawai used poly finishes back then).
The piano had numerous cracks in the finish, of various lengths and
patterns, over the entire lid, going in all directions. The mu sic desk also
had cracks in the finish. The plate had cracks in the finish, as well as the
finish separating from the cast iron.  The entire soundboard showed hundreds
of cracks in it, giving the appearance of "cracked ice".  There was also one
crack in the soundboard that was actually in the wood, extending for about 2
feet.  Also noted were cracks in the wood where the soundboard and the rim
of the piano are connected.    There were 4 keytops that also had cracks in
the plastic.
