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). 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. 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......... 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.... Protek? Please Vince, some advice from experience?

I often have customers turn pins, both to try to get something in tune, and to understand that this is actually an athletic venture at times. les bartlett Diane Hofstetter
