[pianotech] Loose Let-off Buttons

[David Love]

Yes, I didn't pay attention to that fact.  That is very likely the source of
the problem.

The problem on this piano is probably not the loose let off buttons,but
expanding action brackets. Weber grands were made by Young Chang. The action
brackets on YC's for many years, for some strange reason, actually expanded,
which threw off regulation. 

 

 YC used to give you four new brackets, but I don't know if they still do
that, so give Young Chang a call, and ask if they still give them out.
You'll need a serial number of the piano. The customer will have to pay to
have new action brackets installed.

 

The latest information I have for Young Chang is:

But I heard that John is no longer there.

There is a possibility that this 1989 Weber Grand's let-off buttons are
slipping, since 1) they are very loose, and 2) supposedly the hammers began
blocking more than once not long after regulations. This is the first time
I've seen the piano, so I put a pencil mark in the center of the let-off
buttons to check their possible movement when i return in 3 months. 
If they do move, is there a way to tighten them up, like Loctite or
something? Otherwise they will have to be replaced. At least the buttons
themselves, if not the metal thread.
