Sid Stone once held a technical session at his shop in which he applied
heat to each tuning pin via a soldering iron. His theory was to heat the
pin, thereby causing it to expand somewhat and cause the hole to get larger.
I don't remember what his conclusions were (actually don't think there
were definitive results). <br>
<br>
It always seemed to me that it would 1. take forever, and 2. since the
soldering iron would probably take a long time to heat each pin for 230 pins,
it would take forever, and 3. since metal doesn't expand as much as wood, it
would take forever. <br>
<br>
I remember once trying to heat pins wholesale with an iron to achieve the same
ends more quickly, but don't remember any positive results from doing
so.........<br>
<br>
Maybe heat would work? Maybe the piano should be put first in too humid a
condition, causing the wood to swell, then in too dry a condition, causing the
wood to shrink? Actually, you might try some steam in a small section,
then the blow dryer on hot? Also seems like it would take forever.... <br>
<br>
Protek? Please Vince, some advice from experience?<br>

I actually had the music director try to pull a couple "up" a bit,
and he <br>
was quite shocked. I often have customers turn pins, both to try to get<br>
something in tune, and to understand that this is actually an athletic<br>
venture at times.<br>

David Love's idea of putting some current through the pins might work. The
system he's referring to was a large tweezers, seperated at the apex and each
side was insulated from the other with a small piece of fibreboard then
they were bolted together using a nylon bolt and nut. The current was derived
from a DC power converter(doorbell condenser)with the wire with the positive
current to one arm of the tweezers and the wire from the negative to
the other arm. The doorbell condenser is made to be "hardwired" to
household current but an AC plug can be attached and it can be plugged in.
Whenever the tips of the tweezers touched the ends of a center pin,
simultaneously, the circuit was completed, the power flowed and the pin was
heated momentarily. Not impossible in a grand piano pinblock just not
that easy! <g> </span></font></p>
