keybed not level

[Roger Jolly]

Hi Joe,
        There is usually one or two lugs protruding from the plate to
support the keybedWith shims to correct for bowing.  The keybed is srewed
through a hole in the lugs.  Check this first.  You will probably find the
shims are missing. Cut a piece of maple to fit, and jack the keybed back
up. Drill a hole through the shim, and rescrew it to the plate.  A belt
sander it handy to trim the shim to the right thickness. 
 I have managed to stabilize and straighten a few keybeds by screwing 1
1/2" angle iron (steel) to the rear of the keybed.

The fast fix, just shim the rails.

This gives you some choices.

Regards Roger

This is one of those pianos: A "Grand"  console. It appears that the keybed
has sagged. Can any of you suggest an in home repair for the situation? I
know, most of you will say this is a POS or something like that, but it's
the only piano the poor child will have for a few years at this point. I
suppose I could just shim up the balance rail, but the original problem
will still be there. Any suggestions?
