<DIV><FONT face=Arial size=2>After a few attempts, I have worked out =
a
one-swoosh technique for using the Dremel hammer file tool. I start at 8 =
o'clock
and swoosh right around the whole hammer to a good 4 o'clock (basically =
from
staple to staple). Once you get the hang of it you get a real nice =
smooth hammer
surface, good shape, and you go so fast that there is no burning or =
anything
even close to that.</FONT></DIV>

<DIV><FONT face=Arial size=2>Hi Terry,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I tried the router-shaper thing a few =
times on
extremely grooved hammers.</FONT></DIV>
<DIV><FONT face=Arial size=2>I don't like this solution very much =
because I
had the impression the machine is heating the felt very much, =
resulting an
awful tone,real harsh with a lot of voicing work to do after the =
shaping
machine operation.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Of course it is fast, but the other =
problem is
you have to get the habit of using it, because I saw some hammers =
shaped with
this shaper by someone who never did this kind of work before, and it =
was a
total disaster.</FONT></DIV>
<DIV><FONT face=Arial size=2>The hammer set was totally ruined, =
with not
enough felt left, and an awful hammer shape.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>What is your experience with it? =
