to give you more work so close to the holidays, but the

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?</FONT></DIV>
