[pianotech] Guess which pin...

[David Weiss]

I'm curious as to preferred methods  for water/alcohol treatment.  What
ratio of water to alcohol, best method of application, and air drying versus
drying with a heat  source?

I always go for the water/alcohol fix first, as well. A couple of treatments
may work better than one.

Rob,
Many of he Baldwin acros of the 60's -70's have chronic tight centers .
My first test is to depress the left pedal , release quickly and watch
for slow hammer return. Jacks centers can also be tight .I use the age
old alc-water shrink-sizing method and it seems to provide a permanent
fix. Give it overnight and test. Some use a hair dryer to speed things
up but I'd rather see what the center will do on it's own. I then shoot
some protek figuring it can't hurt to slick the center up.
I realize that not every piano will respond ( I.E. center pin plating
problem on the Samicks) but with this Kimball I would give it a try.
It's easy ,cheap and will do no harm AND it might solve the problem.
Just my take,
Best wishes,

 

I agree. Given the quality and worth of the piano, this is a sane approach.
Repinning the action is, I think, abusive to the owner if shrinking will get
you there. And replacing parts (the action) in nominals like this is way way
past cost prohibitive and far beyond sensible for any of my customers. I
must need dumber richer customers. <G>
