John,

Based on what I've seen and tried, I'd say there's a fair amount of gray =20
area in damper timing. =20
=20
I posted here awhile back about changing the damper timing in a grand to =20
decrease "perceived weight."    It worked nicely, with no  noticeable diminu=
tion=20
of ability to play legato. =20
=20
I did it by raising the damper blocks using standard damper reg.  procedure.=
 =20
While the dampers came out lifting pretty evenly, I'll admit  that I'm not a=
s=20
good at that as the Seiler factory techs!  Next time I do  it, I'll try=20
bending the spoons instead, if there are any.

My last two jobs of  the day were on nice, new German-built uprights.  One i=

a Seiler 122,  the other is a Wilh. Steinberg(probably 132 centimeters tall)=

 Both are  really nicely built upright pianos, with very well regulated=20
Renner-built  actions.

I found the touch on  the Seiler to be on the heavy side, and not as=20
controllable as I'd like.   The cause was from the spoons contacting the dam=
per levers=20
very shortly  after the beginning of the keystroke.

At the other end of  the spectrum was the Steinberg.  The hammers were a ful=

2/3 of the way  to the string before the dampers began to lift.  The action=20
felt much  lighter and far easier to control to me.  And legato playing was=20=
no =20
problem.

I thought the  philosophical differences in regulation might be of  interest=
