Heavy touch & no dynamic range

[Newton Hunt]

> The only exception is that the action rail bows towards the front 

Without equivocation that _is_ the problem.

What is happening is the leverage of the action is changing because
the wippen is being pushed closer to the pivot point than the end
ones.

THere are two solutions:

straighten the action rail or replace it, hopefully under warranty.

Change the capstan location to conform to the curve of the rail but
that will raise other issues involving key leverages.

So, the only real viable solution is to replace or straighten the
rail.

Look at the possibility of moving the action support bolts inward and
the upper bolts as well.  Take a stretched thread and check their
alignment.  These should have the power and strength to realign the
action rail.

It is very likely that the rail was warped when it was installed in
the factory so you will need to re-regulate the action including the
timing of the dampers.

I would call Steinway about this and ask for their suggestions.  Call
the factory and ask for Michael Mohr, you are more likely to get more
from him than form any administrator.

Lots of luck.
