Backchecking Height and an incredible help<BR><BR></FONT></DIV>
<DIV><FONT face="MS Sans Serif" size=2>My guess is that if =
the hammer is
checking so high that the tail rubs on the backcheck on the way =
up (just
slightly) it will diminish hammer speed and the volume will be thus =
diminished
making it seem like it is the close checking that is the =
cause.
Otherwise, I put this in Carl Sagan's "Demon Haunted =
World".</FONT></DIV>
