<DIV>Whenever there are more than three leads in the front of the keys, a red
flag should go up. And do not neglect to check the centerpin to knuckle
distance; if it is 15mm it could benifit by replacing with new shanks with a
distance of 17mm. An excellent resource is the Renner parts kit, which enables
one to try different combinations of repetitions and hammershanks. The kit is
free with the purchase of a set of replacement parts. Also, look up the
Pianotek catalog, which carries a wide range of parts in actual size, and
with the dimnesions marked.</DIV>
<DIV>Moving the capstans is a big decision, as not only the weght is changed,
but the ratio of keydip to hammer blow distance. If nothing else works, consider
the Renner repetitions (wippens) with the 'Turbo ' springs.</DIV>

face="Times New Roman" color=#004080 size=3>I’m certainly not an action guru
but last year I did move a capstan line 6 - 7 mm forward on a Baldwin SF-10.
It made a very nice difference. The DW had been in the high 60s
and it came down to the low 50s and felt much better. Fortunately with
that move the capstan was still in a good area of the wippen heel so I
didn’t have to cut the heels off and move them.</FONT> <BR><FONT

working on a 70's Sty B with a horrible action geometry problem. All the
students and the professor hate playing it and I don't blame them! The line
from key balance hole to wip has the capstan way too low making the DW close
to 70g throughout. It has a renner action and hammers. the wips
and capstans are such that I could relocate the capstans back by about 3-4mm.
Would that make a big enough difference in the DW? It won't affect the
line. I looked at raising the stack, but there isn't enough room to
raise it more than 1-2mm. Should I try both?</FONT><FONT
face="Times New Roman" size=3> <BR></FONT><FONT face=Arial size=2><BR>Also, is
the measurement in Steinways made from center of balance rail hole on the top
of the key, or from the back of the key? This is a new endeavor for me
and I don't want to make things worse.</FONT><FONT face="Times New Roman"
