tuning pin bushing geometry

IMO It may be intentional but not  nesessary.  I cap my Bolduc blocks with 6 
mm cap of very dense delignit  bridge cap material to resist flag poling.  It 
is a wonderful feel &  tunes very well.  Leaning against the plate would just 
screw that up.   Know what I mean?

Dittos. Good suggestion.  I do this to many  plates.
Especially Steinway to prevent the pins from possibly
leaning  into the plate hole itself.

A good case  can be made that this was intentional. I
wrote a blurb on this for the  Journal several years
back. Complete with the  geometry.
