<DIV><FONT size=2>Have you had any problems with the Renner hammer (
non-stapled) pulling apart in high humidity regions. In S. Florida I =
have had 5
sets that we installed pulled apart. Obviously the problems were in the =
low
tenor and bass and not the top 1/3 of the piano, which I'm assuming is =
why you
stop where you do. I too have found that the reduction in touch weight =
far
outweighs any concerns for separation in that portion of the instrument. =
But as
a safe-guard for me, wires throughout the rest of the piano are
mandatory.<BR>Tom Servinsky,RPT</FONT></DIV>

<DIV><FONT size=2>According to Wally Brooks, Brooks LTD, the =
staple acts as
a "girdle", helping to keep pressure pushing upwards. His =
source of
information comes straight from Abel.</FONT></DIV>

<DIV dir=ltr><FONT size=2>Is that why the staples in the last set =
of Abel
hammers I used has a noticable gap between the head of the staple and =
the
felt?</FONT></DIV>
<DIV dir=ltr><FONT size=2></FONT> </DIV>
<DIV dir=ltr><FONT size=2>The staple probably had some tonal =
effect back in

been some
time since we've seen much of that in production hammers.</FONT></DIV>

<DIV dir=ltr><FONT size=2>I regularly pull them in the upper third =
