>...if the coil height is, for example, 3/16", then there should be >approximately >3/16" available between the bottom of the pin and the bottom of the pin >hole/bottom of the pin block I think a more important consideration is the thickness of the plate in determining the length of the tuning pin. The method mentioned above takes into account the thickness of the block which is unimportant unless you are using too long of a pin. It also doesn't account for larger diameter wire creating wider coils. I try to use pins 1/8" longer for the single bass strings. There should be some space between the bottom of the pin and bottom of the block in the event of driving the pin deeper so as not to have the pin protrude the bottom of the block as many Vose & Sons did and some new pianos which I think had Wyman on the fallboard and were displayed in Rochester last year. One application where a long pin is helpful is on some vertical pianos where there is a high counter bearing in the bass. Having the coils higher off the plate would reduce the sharp upwards angle of the string. I think there are 2 5/8" pins for this. And too much pin length in the block can make for difficult pin setting especially if the metal is springy. -- Regards, Jon Page PS Terry, your posts (and many others) require scrolling sideways when viewing the list via the archive.
