<DIV>You are absolutely correct Paul. I think maybe I forgot to put my thinking
cap on. But yes, you are correct that I will leave the pin a bit up from the
bottom of the hole. I tend to put my coils pretty close to the plate - closer
than many do - so I guess I don't have much free space at the bottom of the
block.</DIV>

<DIV>This may be based on a dismaying misapprehension of the reality of the
world (much of my life is, after all), but I have always thought that there
has to be room for the pin to be driven further into the block as necessary as
the block ages and pin torque drops. If there is no dimension available at the
bottom of the tuning pin hole for this, the pin is then driven below the level
of the block with all its awful consequences. So I have always just used the
dimension available between the coil and plate as the guide as to how much
room I want at the bottom of the pin hole. If I were to drive the pin down
gradually, I would want to know that, when the coil is approaching the
plate (never less than a string's diameter), the pin is still in
the block and not extending below it. Surely, you don't drive
the pin entirely to the bottom of the hole when you're stringing? I agree
absolutely entirely with your sentiment below about more is better. But this
is one of the small compromises I make to create a practical life to the
pin/pinblock structure. Does this make sense to you?</DIV>

<DIV><FONT size=3>It seems to me that one would always be better off with
more pin in more pinblock - how/why would it be any other way? The more
length of pin in the block will only make the pin more stable - less likely
to enlarge the top of the hole toward the string. The more pin/block
contact, the less friction per contact unit would be needed for any given
pin torque - meaning more stability and longevity. Just seems to me that
more/more could only be win/win.</FONT></DIV>

<DIV><FONT size=3>Paul - what is your reasoning for leaving any empty tuning
pin hole on the underside of the pinblock - and then especially, what is
your reasoning for relating that distance to coil height? How is one
dependant/affecting the other?</FONT></DIV>

<DIV>Correct me if I'm wrong, but I've always aimed for a tuning pin/block
relationship that, irrespective of the actual measures, ends up with the
same dimension between the coil/plate as there is at the bottom
of the pinhole in the block. In other words, 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. The other dimensions then sort themselves out if one
chooses the right pin size and block thickness. Does that make sense? It
almost always works out to approximately what you calculated: between 1"
and 1 1/8" of pin in the hole. </DIV>
