<DIV><FONT face=Arial>Hello all, <BR><BR>I have recently crossed a customer who
asked me to make some custom changes to his S&S model B. Such as raising the
lyre height alittle (he says he has big feet and its unfomfortable for him to
use the height set), so i found a couple of big guys with hairy palms to lift
the piano, and put some larger casters in, which raised the piano by about
almost an inch, which he said was just right.... That got me thinking... I'm 6ft
tall (unfortunately) and one of the pianos I have, the keybed was so low i
couldnt fit my knees underneath and it was a very... shall we say loosly
uncomfortable experience playing it, as well as the same problem as the
customer, i have biger feet than most and pedal height was unfomfortable, so i
took up larger grand sized casters. </FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial><EM>>A simple solution to a problem we don't often
consider. It's worth carrying some extra caster cups in the car
</EM></FONT></DIV>
<DIV><FONT face=Arial><EM>>in case they might help.</EM></FONT></DIV>

<DIV><FONT face=Arial>The piano im talking about is a 43inch console which
i wrote about before, (the one i fell in love with). But after i carried away on
a spree with customizing it for myself, i changed entire regulation, let off is
not set at about 3mm in bass and 5mm in trebble, basically as close as it will
get without bouncing, put on a very tight set of hammer springs, and made a
drastic change of puting in a set of hammers that normally would go into a 290
Bösey...</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial><EM>>Getting let-off as close as possible is always an
improvement (assuming you'll be there to re-regulate when the >humidity
changes) I don't know why you got it closer in the bass than the
treble.</EM></FONT></DIV>
<DIV><FONT face=Arial><EM>>Adding heavier hammers will probably improve most
verticals. It can also be done by adding weight to the existing >hammers. If
it can be afforded, adding high quality hammers will improve just about any
piano.</EM></FONT></DIV>
<DIV><FONT face=Arial><EM>>Stronger hammer return springs will improve
repetition, and also make the action heavier.</EM></FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial> Adjusting capstains i didnt leave the hammer resting
on the hammer rest rail, instead, i adjusted them so that theyr about 5mm off
the rail, in other words the butt is resting on the jack. (adjusted the action
brakets to make sure hammers keep the same blow distance as if they were rested
on the rail)... Shokingly the action became as heavy as on a new grand piano..
however, it has also became intensely sencitive, and repetition is fast and
clean (atleast as far as i can play).... it almost feels like im playing my old
Bosey 290... </FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial><EM>>This is perhaps more change than necessary to
remove lost motion. It will work if the jack springs are strong >enough and
if your technique has a clean release of the key. Sounds like you
moved the action rails a little bit >away from the string plane. Why not just
lower the hammer rest rail a little?</EM></DIV>
<DIV><BR>While i was as it i lubricated center pins and front rail pins with
some oil for guns... yes for guns :-)... and i was astonished and what a
diference this experiment made....</DIV>
<DIV> </DIV>
<DIV><FONT size=2><FONT size=3><EM>>Friction from keys being pushed to the
side while playing can be severe. Sometimes the keypins need to be >replaced.
Most USA technicians favor teflon or Prolube for key
pins.</EM></FONT></FONT></DIV>
<DIV> </DIV>
<DIV>Now my question is, is making such experiments ok? and if so why dont most
manufacturers today who make good quality uprights dont mess around more with
the actions they make?</DIV>
<DIV> </DIV>
<DIV><EM>>Experiments on your own piano are made at your own risk! The
changes you have made seem to show >considerable insight.</EM></DIV>
<DIV><EM>>Supercharged actions, such as you have made, need frequent
attention to play well. Manufacturers generally aim >for long-term security.
PTG sometimes has classes on "super-charging the vertical action."</EM></DIV>
<DIV><EM>>If you haven't heard of the Fandrich vertical action, do a web
search. It's a wonderful action, more sensitive, I think, >than most
grand actions. I wish it would become commonly accepted. But it costs more than
a standard action, and >requires a somewhat different technique to regulate
and maintain, so it probably won't ever pass the "price point"
>test.</EM></DIV>
<DIV><EM>>I hope you'll visit the 3 piano technology schools while you're in
the USA. You might do extremely well in one of >them.</EM></DIV>
