[pianotech] key position at rest

[ricb at pianostemmer.no]

Thanks Jon

Not quite clear on the underlever at ~ 1 1/2 inch.... its higher at
all points then the key end felt... which with a 6 mm rest felt comes
out at 3.5 mm (1 3/8 ")

What exactly are you measuring where when you mean underlever at 1
1/2 inch

Thanks again
RicB

Adding a thicker back rail cloth means more balance rail punchings
to maintain the same height. Try the key elevation at both positions
to see how it affects touchweight. There's that elevation thing again

Since Hume was a copy of S&S, the key end felt height should be
1 3/8" at rest. That places the underlever at ~1 1/2", so start
backwards from there to figure back rail cloth.

The height of the backrail does make a difference in touchweight.

As to the acutely angled capstans, reposition them in line
with a line drawn perpendicular to the cushion at the point
of the Magic Line.
