Thanks, Carlos, a person with actual experience!<br>
<br>
I'm only considering restringing because of breakage in the high
treble. No pigeon patina or soundboard damage, block is tight, action
great except it could use new hammers. But I can see that I'll have to
eliminate as much as possible the climatic changes.<br>
<br>
Did you drill the holes deeper for the new pins?<br>

<div><font face="Arial" size="2">I am just finishing a full
restoration on a 1893 Knabe 57" upright. Why the tuning instability?
This model Knabe is VERY suseptible to temp and humidity change. Only
because of personal reasons did I take on this job. In other words
it's a freebe for the steaming historic Liberty museum ship, the S.S.
John W. Brown. Both ship and piano built in Baltimore. The 3/4 plate
flange is tightly wedged beneath the pin block, and is wraped under the
piano bottom and screwed there. I think this plate and S.B.
configuration does not allow for much movement due to climatic change.
I discovered this piano in a wharehouse on a Baltimore dock next to the
ship. It had been there since WW II covered with what pidgens do. The
tuning was still near 435 and the pins were tight. However the SB was
split pulling the ribs loose. One should note that this era Knabe used
#1 by only 2" tuning pins, take care what size you re-install. We have
replaced the sound board and the bass pin block. The bridges were
fine. We had to remove the bass side of the case to get the extremely
tight fitting plate out of the piano.</font></div>
<div><font face="Arial" size="2">The action has a double stack with
rocker capstans and is very hard to find action parts. After stringing
and kept in proper climate conditions the tuning is very stable at A440
with a booming tone some grands would like to have. I've had the piano
in my shop for about 4 years, working between the pay jobs. IMO this
type of job should never be undertaken with profit in mind. Maybe
before I check out, this old veteran ship of WW II will get a nice
piano for her crew and passangers as she visits ports along the
Atlantic coast. Visit it at <a href="http://www.liberty-ship.com">www.liberty-ship.com</a>.
