Hmm.  My delete button must be on automatic.  You're right and thanks for
putting everything in perspective.

Maybe you are hitting the delete button too fast? It seems to me the
following responses directly address the gap in the pinblock/flange fit. No=
?

Terry Farrell

Is it safe to assume the piano has been strung for a while and has
stabilized somewhere near standard pitch? I would recommend tapping some
hardwood shims into the gaps between the plate flange and pinblock and see
if that helps - if suddenly it becomes stable, then I guess the answer is
obvious. At least it won't hurt anything.

I agree, and the one thing you DON"T want to do is sell him an
expensive wedge and shim job, saying that will fix it, until
you try this.

Ted, from my brief experiences with unstable pianos due to what appears
to be a poor-fitting block-to-plate, it's very important. 1/8" is quite
a bit of play, IMHO.

Hardwood shims..re-tune - evaluate.

Since the customer is confused by previous advice and research, if the
flange fit IS a problem but the pins are tight and I think I'd flip it over
and use wood and epoxy to fill the gaps rather than try to sell a bigger
job. Don't forget the drop cloth!

I guess I didn=B9t explain myself too well in my previous post on pinblock
fitting.  The answers I received so far ignored the fact that the pinblock
to plate flange fit had gaps in it and implied that frequent tunings is the
only solution.  What I need to know is if there is a situation where the
pinblock to plate fit doesn=B9t matter.  This is contrary to all I=B9ve been
told and all I=B9ve read about over the years.  All replies will be
appreciated.

What=B9s the latest on whether or not a pinblock should butt against the plat=
e
flange?  I have a customer who has a rebuilt piano that won=B9t hold tune for
even a day and when I removed the action and checked the pinblock-to-plate
fit I found gaps throughout, some as much as 1/8 inch.  Two weeks after I
tuned it I found it over 20 cents flat and had to give it a pitch raise.  A
few weeks later it was overly flat again and in need of a pitch raise.  I
explained to the customer about the pinblock to plate flange fit but he sai=
d
that he was told by the rebuilder that such a thing was not important.  To
top it off he did some research and got conflicting comments.  Some said th=
e
piano is OK as is while others held to the conviction that the gaps in the
pinblock are the problem with his piano.  I need some backup in my
assessment, either pro or con.
