roughing in
key height/level (65 mm - spec is 64.5 mm), dip (10.2 mm), blow distance =
(47 mm)
from manufacturers specs. The 10.2 mm dip gives me 1/16" let-off and =
0.025"
after-touch (don't you like how I mix metric, english fractions and =
decimals
together?). So that seems real nice. I also suggests I've got the =

low. I've got the hammer rest rail plastered against the wippen flanges =
and the
shanks just barely clear the rest rail felt. Also, to get the 10.2 =

I have to remove all the punchings under the front rail felt. My guess =

worked. Just seems like something is not quite right, and I'm not =

the original manufacture of this piano (about 1990) too much credit - or =
