When you say spongy, I'm led to think that the front rail punchings are
what you're talking about. Try a set of Wurzen felt punchings
(<a class="moz-txt-link-freetext" href="http://www.pianofortesupply.com/">http://www.pianofortesupply.com/</a>) and see if that helps.<br>
<br>
Key dip is typically 10 mm, a bit more than 3/8". Aftertouch might be a
little less than 1/8" (of key dip); check for the jacks clearing the
knuckles by a 1/32". <br>

<div> Hi Folks, </div>
<div> </div>
<div> </div>
<div> Here is a question regarding regulation of aftertouch when
depressing keys. When regulation actions, I like to break key movement
into eighths. I figure that most normal key depths are 3/8 inches.
Thus, the first 2/8 of movement is smooth..then there is that last 1/8
if aftertouch. I like to feel the slight hesistion (clicking feel).
However, there are times when that aftertouch feels too spongy
regardless of what I do....jack regulations, drop, let off, etc....
About the only thing that seems to help is a slight increase of
depth....but why would most keys have the "normal" feel of aftertouch,
while a few are unresponsive...????? </div>

<div> Any ideas? </div>
