Fischer Upright

Hi Stephen,
                  I have done a couple of verticals with this problem.
On most plates you are quite safe in drilling out the plate holes to accept a
plate bushing.  The plate webs carry most of the stress.
Select the correct size of drill, so that the bushing is a snug fit. Hand ream
the pin holes.
This will cut down on any flag pole effect, and improve the tunability of the
piano, depending how thick the plate is in the pinning area.
Don't worry if the pin hole and bushing hole don't quite line up, when you
drive the new pin in it will find it's way home.
Roger
