<p>Greetings,
<br> Since the spring doesn't lift the hammer in fast
repetion, but rather,
<br>increases the speed of the key return, the effect of stronger springs
has,
<br>imho, little to recommend it for additional speed. As long as
it is strong
<br>enough to slowly lift the hammer from check, I have not found increasing
the
<br>spring to help repetition speed. Personally, I set the springs
to lift the
<br>hammers as fast as possible without feeling them lift through the key.
<br> As mentioned by Stan, the stronger the spring,
the more resistance is
<br>felt on the pianisimmo blow. This is troublesome when setting
up an action
<br>for maximum sensitivity.</blockquote>
<p><br>This is not in my experience Ed. Or perhaps it is just another way
of saying the same thing. Since the spring pushes at both the hammer (upwards)
and the opposite end of the lever system (the key downwards) I suppose
you could view it in this manner. As for the concern on pianisimo blow,
of course there are limits to how strong you can set the spring. I have
seen spring strength recommendations varie a lot. Some say it should be
strong enough to simply hold the hammer at check height, others say a very
slow rise, others say a firm and definant rise. I like your description,
"strong enough to not feel them lift through the key" Tho I would rather
put it .... "Strong enough to <i>just barely</i> feel them lift through
the key".
