<DIV><FONT face=Arial>Interesting question about what I see as an =
imperfect
science, at best. I'm wondering if just testing the hammer for =
side-to-side
motion while holding the butt (upright) or flange (grand) would be =
accurate
enough to indicate wobble problems.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Here's a weird idea: Has anyone tried a drop of =
"pinblock
restorer" in a worn birdseye to tighten it's grip on the pin? The most =
horribly
wobbling hammers obviously occur when the pin has slipped out of one =
side of the
flange, which surely indicates a worn birdseye, rather than redoing =
the
bushings and repinning, I wonder if "dope" would work.</FONT></DIV>

FAMILY="SANSSERIF">We all know that a hammer is supposed to swing 4 =
- 8 times.
If it is less than 4, then the bushing is too tight. If it's more than =
8,
supposedly the bushing is not tight around the pin, and that might =
cause the
hammer to wobble up to the string, which will eventually lead to =
uneven wear
on the hammer, whcih creates tone problems, ya da, ya da. =
<BR><BR>So
here is the problem. I've got this hammer with only 3 swings. So that =
mean the
bushing is too tight. Before I take the pin out, ream the bushing, and =
put in
the same size pin, I put a little Protec on the bushing. But now, all =
of a
sudden, I've got 10 - 12 swings. According to the above presumption, =
the
bushing is now not tight around the pin any more. <BR><BR>Or is it? =
Has the
introduction of Protec shrunk the bushing to the point I need to ream =
and
repin with a larger pin? Or do I leave the original pin in there, and =
allow
the 10- 12 swings? <BR><BR>Wim =
