pinblock drills and drift

[John Ross]

Hi Roger,
What I forgot to say was that, the piano started with the pins and strings
removed, and the plate in place, but unscrewed.
The plate was lifted off, dowells drilled out, and pinblock removed, in the
three hours. All done by one man. The only time any help was given, was to
flip the plate.
