<font size=3>The easiest way to increase touchweight on an upright is to
install Jiffy Leads.<br>
The benefit of these is that they are equally easy to remove or alter
their position.<br>
<br>
Make sure the action is properly regulated so as to be certain that
weight is<br>
actually all that is desired. I think it was mentioned that having the
dampers lift<br>
a little sooner will add their resistance sooner in the keystroke thus
raise th<br>
touchweight, check the damper spring tension as well as well
as the jack spring<br>
and hammer return springs.<br>

touchweight. On Baldwins and other brands where the action sits on
thinner<br>
posts, you can actually bend the post front to back changing the
leverage.<br>
We're talking slight. This works. However, on the Yamaha's this
is<br>
impossible (short thick stubby screw on a wooden base) without removing
the<br>
post and the wooden base it sits on (filling screw holes and redrilling)
and<br>
repositioning the base itself in new screw location. This process
makes it<br>
hard to experiment with different positions. Again, it works.
By tilting<br>
the botton of the action away from the key the action is
heavier..like<br>
pushing someone further out on a seesaw. But we're not talking
much, keep<br>
an eye on whippen felt to capstan contact through the stroke and
consider<br>
wear, etc. I do not believe this affects repetition. The
solder idea has<br>
worked well, too. Have fun, but be cautious!<br>

What about this,<br>
<br>
for increasing leverage on the *whippen*, manipulate the capstan wire
(if<br>
present) in such a way that the capstan touches the whippen closer to
you<br>
than it did before.<br>
Would you think this to be a bad idea?<br>
It wouldn´t have to be really tipped or anything but I wonder if this
would<br>
increase the wear and tear on the overlying felt.<br>
<br>
<br>
