<DIV><FONT face=Arial size=2>Ah. When I started at IWU, I =
followed a
technician who was hard of hearing--so he couldn't hear the Teflon =
clicking the
faculty complained of. His solution was to pin everything fairly
tight. <wince> Anyway, I repinned the worst of =
them, but
they were still on the heavy side. There was no rebuilding budget =
at the
time (and David Stanwood was just coming out with his touchweight stuff =
when I
moved away). I simply said that I had done what I could until the =
action
could be replaced.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>So, if there isn't a =
touchweight issue with a
Teflon repetition and a felt hammer flange, the bulk of the problem must =
be in
the hammer shank/flange. Did the knuckle mounting distance change =
from
Teflon to felt or was it just the nature of the Teflon? Or, did =
the
knuckle size change (or whatever)?</FONT></DIV>

<DIV><FONT face=Arial size=2>PS Following someone who cannot =
hear and
won't admit it, is rough. He also over-tightened screws--again to
compensate for not being able to hear such clicking. Dealing with =
broken
damper wire set screws was my least favorite job.</FONT></DIV>

<DIV>Hi Barbara,</DIV>
<DIV> I have a hybrid D from 1981. No touchweight =
problems.
The bulk of our B's, from 1965 or so (teflon I) are all teflon (other =
than the
few I have replaced), and tend to have flange friction issues - and =
perhaps
geometry in some cases - leading to touchweight problems (I =
investigate, see
that the real answer is parts replacement, and put it off till later. =
No sense
doing a bunch of work that I'll just redo or throw away later with new =
parts).</DIV>
