Counter bearing treatment

* More like x amount from the height of the hammer flange center, defining,
and governed by the hammer length, bore distance, strike distance,
whatever. With a rocker  capstan and sticker action, the distance from the
keybed to the strings can be as long as the legs allow, if you don't mind
sitting on the floor, or in the basement, to play it.

 >Thus to

* Only if you feel that you might want to pull the action at some point.
Then again, I suppose the keybed could be made to drop down for action
access. Possibly a slow fall feature... Oooooo.


>	I have often wondered why in grands the pins are highter than the strings
>or why they could not be the same level as in uprights. 

* They could be if you were willing to tune upside down in the action
cavity. This would have the added benefit of not collecting dust and paper
clips in the tuning pin field. CA'ing the block would be a matter of simply
pouring it in the holes from the top. Tuning pins could be made with an
Allen socket in the bottom (top?) for an alternative Felliniesque sort of
tuning experience. One could submit a synopsis of the process to the List
for the edification of us all... perhaps.

  ---rici wonder

* With whom? Is the recipient of these calls still free to receive
un-monitored phone calls, or is it by appointment now, governed by the
medication schedule?

Hey, it ain't my fault! I just checked my mail, and there it was.
