Henry,
My experience in North Texas/Southern Oklahoma indicates that this process
will last for a few years, depending on the degree of verdigris and climate
control the piano has to endure. Unlike the zapper device, you can heat one
side of the pin and heat sink the other though it is still not great for the
birdseye. Unfortunately, the temporary fix sometimes works so well the
client will postpone parts replacement indefintely. I follow a couple of
guys occasionally who did this procedure for years with relatively few
problems over time..Like Ms. Kline, I have found "lubricated" parts to be
more problematic.
Best,
Dale

Had excellent results in freeing up a very sluggish action by heating the
hammer flange pins with a soldering iron. My question to those who have done
this: How long can this freed-up condition be expected to last?
The owner plans to have this 81 year old S&S rebuilt in 3-4 years, so is
hoping to keep it going til then. My inspiration for the heat remedy came
from postings some time ago on this most informative list. Thanks & regards,
Henry Kopek, RPT Chicago Chapter
