Expanding brackets on a Cline

[David Love]

I have changed a number of YC brackets so, yes, I do know where this is
heading (unfortunately).  They said they bought it three years ago but I
have not looked up the serial number-it does seem a bit young for that
problem.  The piano wasn't blocking everywhere but there was enough of it
that it made me think about it.  The customer did say that it had been a
chronic problem.  I didn't realize the pianos were made by YC.

David,

 

The Clines that I am aware of are made by Young Chang.  If you have followed
the recent thread about Young Chang action brackets, then you know where
this is heading.  They have had problems with expanding action brackets
which will cause the kind of blocking you are describing.  A tip from Allan
Gilreath: don't make temporary individual adjustments of the let off rail.
Shim the whole rail down with some balance rail punchings.  That way you
won't have to make so many large adjustments when you put new brackets on.
One thing that does not quite add up though is the age of this Cline.  I
wonder if it wasn't built some years earlier than you think.
