The basic mechanical principles are constant. As pinblock grip (tuning pin friction) increases, the more the top end of the pin will have to turn before the bottom end (in thepinblock) finally gets to move. It's a matter of the pin torsion overcoming pinblock grip. The challenge as I see it is not in how to twist the top end enough so that the bottom end will move. Rather it is to guess what turn at the top will turn the bottom an amount equal to what the top end *should* have turned in order to make the required wire change in the speaking length. The variables are string and tuning pin friction, the desireed amount of tension change in the speaking lkength, and (last but not least) our competence.
