Rebuilt Action Touch is too light

[Marcel Carey]

Brett,
 
In your case you might have to remove leads from the keys to make the
action a little heavier. Usually keys are weighted in front of the
balance rail. If you want to make it heavier, you might have to remove
some of these. To do this, you will need to put leads on the back of the
balance rail and measure how far from the rail you need to add which
size weight. Then you will have to calculate and remove the equivalent
from the front.

Objet : Rebuilt Action Touch is too light



Thanks Ed for your Questions,

One the Owner/Teacher loves the fast & light action . When I first
assembled it and set it up I felt that it might be to light  as far as
touch .  The other teacher says it's to light . She and some of her
students have trouble with control of sound .

When I first looked at the Hammers from Renner to me they looked smaller
& felt lighter than the originals . The whippens came from Yamaha . So
the only parts that might have made this action lighter would have been
the hammers shanks & knuckles. I used the specs from my action hand book
for regulation . I guess I need to read up on the key weighting and
learn how to finish the job right . I just thought that maybe there was
one of those rules that might apply to this like if light do this and if
heavy do something else as far as regulation . But if it's the lighter
hammer assembles than I guess the right way to correct it is by adding
the weight back . No short cuts .?

Thanks for any ideas , Brett

It is not clear from your post what the complaint is.
Is the "local teacher" satisfied that the action is fast and light?
Is the other teacher complaining it is too heavy?
What kind of "hard time" are the students having? Hard time pressing the
keys or hard time controlling the sound?
What is your impression of the piano?
Have you voiced the hammers?
Have you taken basic down and up weight measurements?
