fallboard vs. keytops

[reggaepass at aol.com]

 Hi Rex,

Thanks for your input.? I had the action in and out and used the una corda pedal, so it doesn't appear to be interference with overly long leg bolts in this particular case (although that's a good one to be on the look-out for).? The fallboard pins COULD be in the wrong place--hope to sort that out with the manufacturer tomorrow.? I'm not sure what you mean by them being "installed upside down," though.? Could you please clarify that?

Thanks,

Alan Eder

Does the action shift correctly? One of
the things I have seen working for a piano store is that the movers sometimes
do not put the leg/lyre bolts in the correct place. Some pianos have shorter bolts
for the front legs. If the long bolts are put in the front, it will cause the
action to be lifted on that end. Usually the complaint is the piano will not
play correctly in the treble, but someone may have lowered the hammer line not
realizing that the end of the keyframe was in the air; resting on the leg bolt
and not the keybed. This could cause the treble keys to be high enough to be depressed
by the fallboard. The quick check for this is to try to shift the action. It
will not shift in this condition. (You will also have to back out the offending
bolt to get the action out.) The solution to this problem is to take out the
offending bolt and remove one bolt at a time from each of the other leg and
lyre positions and compare the length. (If you take a bolt out, check it and
replace if not shorter before you take out the next bolt you will not have to
worry about the piano legs or lyre falling off.)

Course it could be that the pin is in the
wrong place or installed upside-down.

Just a couple of obvious (and not so
obvious) ideas on things to check.
