size=3>I've only had to use vellum once on one of these, and I fudged =

the <BR>top 1/2" of a dress kid glove my customer supplied, but I have =
needed to
do <BR>some other repairs. The jack springs are held by thread loops (at =
least
on <BR>the squares I tangled with) and though most are amazingly intact, =
now and
<BR>then one has broken. Not hard to replace (I used silk cord) except =
that
<BR>getting access to the part is hard. I did replace a hammer shank on =
a
<BR>square once, for a lady who was retiring and wanted to play. She had =
a
<BR>photo from 100 years before, of some fairly rough-looking male =
relatives
<BR>standing in front of her piano, from the 1880's. I needed a 3/16" =
shank,
<BR>but longer than a spinet shank. I had to get a 3/16" dowel from the
<BR>hardware store."</FONT></FONT></DIV>

<DIV><FONT face=Arial size=2><FONT face="Times New Roman" =
size=3>1. Vellum is
redily available from Fletcher Newman, U.K.</FONT></FONT></DIV>
<DIV><FONT face=Arial size=2><FONT face="Times New Roman" =
size=3>2. Use fly
casting "backing" line or woven casting line. Available from your local =
sporting
goods store. Access to the spring, etc. is accomplished by removing the =
key,
(which can be done w/o removing the stack, BTW!). Remove the rocker =
capstan.
drill out the "plug", that holds the string in the jack. Insert the =
casting line
into the spring loop, double over and insert into the hole in the jack. =
Use a
round wooden toothpick and a dab of cold hide glue. This will be a =
"force fit".
The trick is to get the spring to START to engage, when the jack is a a =
45
degree angle to the key top/rocker capstan top surface. If it engages =
earlier,
the spring tension will be too strong and repetition, (such as it is), =
will be
greatly compromised. If it engages "late", the jack will not have =
sufficient
"force" to seat under the butt and the darned thing will "cheat"! Also, =
when
re-installing the key adjust the lost motion as it would be in a spinet. =
Lost
Motion is needed! (Just a "wink" is sufficient.)</FONT></FONT></DIV>
<DIV><FONT face=Arial size=2><FONT face="Times New Roman" =
size=3>3. Square
grand, 3/16" hammer shanks are redily available from Schaff! However, =
they are
labled "Reed Organ Pallet Rods"! These are longer than spinet shanks, =
but of the
same stock. Warning: There will be loads of "rejects" so order at least =
100, if
you are doing misc. replacements......1000 if you are =
re-hammering/shanking an
entire action!!!</FONT></FONT></DIV>
