<DIV><FONT size=2>I don't know when you might receive this as I assume =
it will
take at least a few days to return to Australia from Reno, but I have =
some
questions about your action design. I have copied the pianotech =
list as I
am sure that those who did not have the opportunity to see it will be
interested. I could not attend your class in Reno due to some =
conflicts so forgive me if you covered this material there.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>1. I assume that the layout is designed to put =
all the
friction points on the convergence lines. The most noticeable =
change
therein is the capstan which angles toward the front of the key =
rather than
the back. Is the angle of the capstan set at the tangent =
to the
arc scribed by the movement of the key at that point, or is it a more =
acute
angle? Is the idea that with the wippen heel set at 90 =
degrees to the
capstan that there is no sliding and thus reduced friction? It =
seems that
this would also result in greater wippen speed since there is no lateral =
movement allowing you to use a slightly longer knuckle =
radius.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>2. What is the product of all the distance =
leverages and
does it correlate to a specific key dip/blow distance combination? =
Have
you found generally that there is a specific and absolute
correlation between total distance leverages? For example, =
TSDL = 6.5
correlates to 10mm dip and 45 mm blow, and for any deviation of x a =
corresponding change in dip and blow of y must be =
made.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>3. What is the friction range in the =
action that
you had in Reno.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>4. Your shank uses a 20mm knuckle to center =
pin
radius. Was this done primarily to reduce friction at the
knuckle because of your intention to use such a heavy hammer? =
</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>5. Just for fun. All things being equal, =
what
happens if you reorient a Steinway capstan toward the keyboard by =
8-10
degrees, put it on the line of convergence and spin a slanted heel =
around
backwards to put the two in line?</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>It was a pleasure meeting you. It's a =
beautiful piano
you've produced and I wish you the best of luck with your =
project.</FONT></DIV>
