Performance pianos require constant adjustment of the top action with
seasonal changes. If you set<br>
the letoff close in winter, they'll be blocking in summer.
the TLRG from Pianotek is perfect for these<br>
seasonal touch-ups.<br>

You don't mention (modestly) who invented the invaluable Taut Line <br>
Regulation Gauge! Yes, it helps a lot, especially for those moments
<br>
when an action HAS to be finished, PRONTO, and returned for an event.

I concur with the "fastest rise without the bounce". Springs
seem <br>
stronger as centers loosen with wear, but they aren't. In Linfield <br>
College's performance instruments, I've found a lot of what seem <br>
to me overly loose centers, even though there is no side motion. <br>
Controllability suffers, and to avoid the bounce coming out of check,
<br>
springs would have to be too weak for the quickness of jack return <br>
which I would like. I'm gradually trying to break loose some time <br>
to repin all hammers and many wippens and rep levers on these <br>
instruments, with great improvement in feel. Luckily we don't have <br>
the seasonal high humidity to contend with, just lots of use. Given
<br>
the amount of use these pianos get, pinning to six swings seems <br>
not all that economical, since they'll just get too loose again <br>
too soon. I like closer to 4, so long as pianos don't have a weight
<br>
problem, and friction elsewhere (such as keypins) has been minimized.
<br>
Of course, 4 would be ill-advised in winter in places with damp summers.
