<DIV><FONT face=Arial size=2>Jon,</FONT></DIV>
<DIV><FONT face=Arial size=2>I have several sized jigs for cutting =
the cove(s).
I've never been happy with the cove choice of most hammer manufacturers =
and
prefer to do my own. It takes about a half hour to do this, so no biggie =
there.<G> On some of the weird stuff I work on the hammer =
length/moulding
size, etc. is not completely available. On really olde Steinway =
Uprights, they
actually coved the underside of the upper treble hammers to reduce mass =
and get
a more ringing tone. I've experiment, in this instance, and have found =
that this
is the true issue they were addressing.</FONT></DIV>
<DIV><FONT face=Arial size=2>I'd say, if the piano sounds fine, =
especially in
the upper treble and the touch is within acceptable limits, I wouldn't =
worry
about it. Because I bore all my hammers, myself, coving has just become =
part of
my procedure of prepping the hammers for installation. Mileage may
vary.<G></FONT></DIV>
<DIV><FONT face=Arial size=2>BTW, the Jigs are easy to make and use. =
The trick
is to use a Forstner Bit, (the real one(s), not the Chinese =
knock-offs!)! Of
course, this means you have to learn how to sharpen them puppies, (which =
ain't
fun!), to get a consistant cut. Another one of them "woodworking" =
thingees that
are basically therapeutic.<G></FONT></DIV>
