Aftertouch

[Farrell]

Some would say 0.025" is a nice aftertouch. One-eight-inch aftertouch would be on the order of  0.125" - that's huge!

  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 (http://www.pianofortesupply.com/) and see if that helps.

  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".

    Hi Folks, 


    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...????? 


    Any ideas?
