Unfortunately, that doesn't make a lot of sense either. Lots of years back, someone on list pointed out that tapping a pin less than a millimeter deeper into the block often makes way more torque difference than is reasonable for the "fresh wood" presumption. I think it was a good observation. > Also, one thing I missed was that our eval was turning the pin just to > break the initial friction similar to tuning.

(sorry) Another thing: I've noticed that pin torques two or three days after stringing feel higher than when you're installing them. This may be a body calibration illusion relative to the different levels of violence imparted whether stringing or tuning, and I've never taken actual measurements, but it's worth a look. How do those test piece torques match up today? Ron N
