IMHO, either the pin turns on it's own or it doesn't. How does your experience differ? FWIW, yes, some tuning pins have less torque than I would like, but that doesn't mean that they spin on their own..... Terry Farrell</blockquote> Stop trying to blind me with science Terry.  I meant that generally the pins had less torque than I would like, but I did not measure the torque.  Two or three were loose enough to "instantaneously" move back a substantial amount when I put the lever on them. I hammered them further in and they gripped. With regard to "IMHO, either the pin turns on it's own or it doesn't.".  What timescale and amount of degrees or fractions of a degree are you talking about for the turning (if we are to be in measuring mode)?  Are you talking about a hundredth of a degree in six months, or 30 degrees in a quarter of a second?
