=2>There is
a Mason & Hamlin upright model 50 (vintage 1975) I service and at the =
last
tuning the owner was complaining about bobbling hammers. The hammer pinnin=
g is
very loose. I played around with the note that was bothering her the most =
and
through a combination of repinning and strengthening the hammer return spr=
ing
was able to all but eliminate the problem. The piano is in good regulation=
.
Here's the issue: The action is really poorly made. 1975 was not exactly t=
he
golden age for these. In repinning the one I did, I could see that the fla=
nge
bushing cloth was poor quality. It would be wonderful to replace the whole=
action, but that's not going to happen. Does anyone know if it's possible =
to
get replacement hammer flanges? These flanges are different from the gener=
ic
ones sold by piano supply houses. If that's not possible, I have to go wit=
h
rebushing what's there. Any recommendations on a good source of flange bus=
hing
cloth? I know M&H are making these again. Anyone know if the action de=
sign
is the same?<BR><BR>thanks,<BR>Aaron<BR><BR></FONT></BLOCKQUOTE></DIV>

<DIV>The problem might not be in the flange pinning. You need to figure out =
why
it is bobbling. It could be that there is not enough key dip. Even taking ou=
t a
.005" punching is sometimes enough to make a difference. Also check the
condition of the catcher. Roughing it up a bit will give the back check
something to grab a hold of. Try pushing the back check forward or back a
little, and see if that will get it to check better. </DIV>
