aftertouch

[tompiano at bellsouth.net]

With the measurements you have provided, my guess is that you are trying to keep key dip at 3/8" and you are beginning to realized  this is too shallow for this instrument. Correcto! . Experiment with a few keys and see how increasing your key dip affects the playability of the instrument.

> I'm working on a Baldwin console.  The plate has 40 stamped on it.  It's a pretty good piano and is about to go back to its home.  The action is a little on the small side .The regulation is pretty good but I am needing more aftertouch.

> Key height is 2 1/2" above the keybed.
> Hammer Blow distance is 1 3/4" to strings.
> Letoff is about 1/8" in the treble and 1/4" in the bass.
> The bass and midrange white keys are pretty good with correct aftertouch.  Some of the whites in the higher treble have shallow aftertouch.  
> Sharps have little aftertouch and are terrible.  They sit 13mm above the whites.
> There is nothing obviously wrong such as too many punchings under the keys. This piano does not appear to have been tinkered on by an unqualified toooooner.

> My choices are:
>   1.. Raise keys.  
>   2.. Decrease hammer blow distance.  
>   3.. Increase letoff.
>   4.. Increase dip.
> With choice 1, I'm hesitant to do this as the keys are right up against the rail.  With choices 2 & 3, I feel like I'm losing power.  With choice 4, I feel like I'm chasing symptoms and not the real problem.

> It may be that the action is compact enough that I just need to squeeze what little I can from all 4 choices.
