Hello fellow technicians.
Thank you to Jack Reeves and BYU for hosting us and this forum. I don't
understand how it works but I appreciate it. It is very informative and a
wonderful aid in keeping us abreast of current thought.  I can see as we
approach the long awaited relief from the Christmas onslaught our
responsibilities are lessening and the E-mail board is heating up.
The discussion regarding touch weights and action response has raised a
related question I have always had regarding the role of the damper
underlever lead weights.  How much lead is correct? Manufacturers seem to
load up this area with plenty, to the point of over kill.  Is there anything
wrong with regulating this area, by removing extra lead weights or even all
weights if possible , leaving in place simply enough weight to accomplish
sufficient dampening? Is the purpose of this weight simply to pull the damper
down, and of course to keep it down against the rebound of the string, or is
there something else negatively affected here if there isn't an "overkill
sufficiency" of down weight?  If the string can be perfectly dampened without
that weight,  with no bleeding or lingering of sound, that would seem
advantageous to me. I know on uprights we get excessive weight from heavy
damper return springs.  The same must be so for these heavy weights in
grands?  Any thoughts?  This mass must have a negative affect on
responsiveness. Just thought I'd ask.

In recovery now & looking forward to Christmas
