So, as I understand your reasoning (ddf's) the angle that the string pass
through after leaving the V bar or agraffee determines how much of the
string energy is reflected back in to the standing wave on the speaking
length.  Would you use the same argument for greater side bearing at the
terminating bridge pin?  Why not?

Yes, your interpretation of the picture

is indeed correct.  Since the board was over a hundred I felt that I need to
control the amount of bearing across the back side of the bridge and reduce
it to a bare minimum.  The ability to select the correct diameter and the
lubraciousness of the copper wrapping led me in this direction.   

Originally the Chickering had felt glued to the plate just in front of the
hitch pins.  Would you have left the felt there?  If so why?
