<DIV><FONT face=Arial>Hi,</FONT></DIV>
<DIV><FONT face=Arial>My understanding of the crown, is that the =
centre is the
most played on, and this is where the felts would be compressed the =
most. So to
beat that problem, a crown is put in the centre, and with playing it =
settles,
straight.</FONT></DIV>
<DIV><FONT face=Arial>I just accepted that as fact, it may or not be
correct.</FONT></DIV>

<BR><BR>Steinway recommends a 1/32" crown. I have a key level stick =
that has
two sides, a straight side and on with a 1/32" crown. Some pianos have =
the
crown. Others don't. I don't know if it makes all that much of a =
difference,
but if there is a crown, keep it. If not, don't put one in. =
