Ditch the tuning pin bushings

Paul,
Many years ago, Piano Manufacturers actually used a tuning pin like you =
describe. It is called a tapered tuning pin. They had many advantages. =
One of which is, slight tapping of one that is considered loose, fixed =
the problem. These pins were approx. #1 pin size at the bottom and =
approx. 3/0 at the top. (that is not a typo: #1 tuning pin =
dia.=3D.265"). Hope this clarifies for you.

  What about a tuning pin that is oversize from just under the coils =
down and size 1/0 or 2/0 from there up?  That would give added stiffness =
to the pin in the portion that passes through the webbing without =
sacrificing the better torque and smaller string coils that you get with =
standard size pins.  It also allows reuse of the old pin block (if it is =
in good condition) while still retaining the benefits of standard size =
pins.  (David Love and David Ilvedson know that I have a special reason =
for asking this question.)=20

      Another thought though; someone mentioned to me the problem of =
restringing=20
      with oversize pins -- something I'd not really thought about since =
we don't=20
      do this.=20

    Could you make clear what size pin qualifies as "oversized", =
assuming that 2/0 was the original?  Thanks.=20
