Bob Hull asked: "2. What are Kawai pinblocks like to duplicate? Any
labor increasing characteristics?  I have read that a
great pinblock to flange fit is not essential since
the bushings and plate bear the pull of the strings."

A Kawai Pinblock is pretty standard and should not be a problem. As to =
the "flang fit", don't fall into this trap! It may be espoused that =
there is not a need for a "pefect fit", and that the plate and bushings =
bear the load. That is pure B.S. IMO. Always attempt to get a good fit =
of a replacement pinblock. This will manifest itself in a quickly Stable =
piano. i.e. you won't have to tune it six gazillion times to get it to =
settle down, after restinging. Careful fitting of the pinblock is a =
must. The plate bushings do nothing! (Unless they are of a different =
construction.<G>) Yes, the plate bears most of the force. It was =
designed to do just that. But, the object is not to bear the force as =
much as to distribute the force and create a stability in the =
instrument.
If the piano you are doing the estimate on, has a lot of falseness in =
the strings, you'd best repin the bridge(s). No need to "put pliers on a =
few pins"! Just listen.<G>
