Jack popped out

[John Fortiner]

Check the jack spring.  I recently had this sort of problem on a Hamilton
243 and discovered that a spinet length jack spring had been installed on
that particular note rather than the longer spring that belongs there.  The
spring was not broken, just way too short.

Greetings, 
 
        I had a customer call about a key that would not play. When I got
there and looked, at it the jack had flipped out from under the butt and was
'stuck' I simply lifted the hammer and pushed the jack back under. Then I
asked if she was doing some loud hefty playing, as in Beethoven when it
happened, and she said "Yes!...That's exactly what I was playing,
Beethoven!".
 
       My question is should this even happen at all? The key was regulated
ok, no excessive space between jack and butt on a normal blow.  I have seen
pianos that were moved and tilted in such a way that the jacks popped
foreward, but very few while playing that this happened. It is a
Baldwin/Hamilton console from the 60's 70's era; a nice work horse of a
piano.
