<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I'm presently working on a 1909 S&S K52. =
It was
professionally refinished. I've so far replaced the =
keytops, rescaled
with PSCALE, and restrung using wound strings on the first 5 notes above =
the
bass break. </FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Prior to stringing I lowered the plate w/o removing =
it by
using a saber saw to take the thickness or height of the dowels down by =
one saw
kerf. As the screws rose toward the treble side I used progressively =
thinner
blades (some by hand for accessability). Along the bottom I used =
more than
one kerf as required to get the downbearing I wanted. I found =
I had
to remove most of the screws completely and lube with bees wax in order =
to pull
them down. Rust and corrosion made them just too tight to =
move. This
worked rather well. I cleaned the bridge by clamping a brass brush =
to the
blade of an electric carving knife. The brass brush was about the size =
of a
toothbrush. Then by sections I warmed the bridge with a hair drier =
and
applied Epotec 301 epoxy to all the pins. I then rewarmed with the =
hair
drier to help penetration of the epoxy. Since that is slow setting =
stuff,
I waited awhile and then removed the excess by brushing the whole bridge =
with a
dry paint brush, wiping the brush often. I ended up with a nice =
looking
bridge with a coating of epoxy on it. Might not look good enough =
for a
grand, but looks okay. After overnight cure, The surface seemed a =
bit
tacky, so I sprinkled talc on it and brushed it in and then blew =
off the
excess with my air hose. That worked pretty good considering it =
didn't
take long at all except for the cure time.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>So now, I'm starting to regulate and replace the
dampers. Hammers are decent but not original.</FONT></DIV>
<DIV><FONT size=2>I now have several questions, since I'm not one who =
(only
works on Steinways), actually seldom do.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>In the piano action handbook it calls for .4 inches =
dip.
I see specs that vary for dip and I've thought that since the dip =
is the
first interface between the performer and the instrument it would seem =
that
uniform dip from piano to piano would be desirable. In most cases =
regulation can
compensate for different dips, so a uniform dip could be =
used. I'm
not a player so perhaps I don't have a feel for this. Anybody have any =
strong
opinions on this? How sacred is following the manufacturing specs
regarding dip?</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I found that repetition was poor in the high =
treble. I
found action centers were a bit tight especially the jack. After =
water and
alky, protec and the zapper, it repeats better, but key 88 has a chunk =
of lead
in it and the dowel capstan pushes up about14 grams. Now the =
weight of the
whippen is not much more than that, so if there is some lost motion then =
the
whippen may not even push the key down beyond the lost motion =
and that will
produce a key leveling problem.</FONT></DIV>
<DIV><FONT size=2>Question: What is the criteria for jack
tightness?</FONT></DIV>
<DIV><FONT size=2>A gram gauge at the end of the jack should read no =
more that
what?</FONT></DIV>
<DIV><FONT size=2>Question: Should I remove lead to get better =
repetion
and have better up weight and down weight? Or am I missing
something?</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Last question: The dampers of S&S uprights =
as well
as Mason and Hamlin are very different than most uprights. The =
felt
between the block and the popsicle stick is much thicker than standard =
supply
house dampers. They have the popsicle sticks in the center section as
well. What do you do to replace those? Steinway has a set of =
dampers
in their price list for 121 dollars, and I don't even know what they =
consist
of. Anybody use them, or do you just adapt standard =
dampers?</FONT></DIV>
