Michelle, <br><br>
About 35 yrs. ago when I was first learning, Aubrey Willis (probably
unknown to you) told me something that helped me many times: "Always
remember that when you can't figure out what a given problem is on a
note, that you have 87 other notes to compare it to and see what's
different about that one"! <br><br>

Check for tightness in any parts, not just flanges. It could be in
the sticker guide rail bushings as well. Or, as John Ross
suggested, there may be hammer return springs broken. They come off
when we pull dropped mutes out of the action. When that
happens, most of us put them back in the slot most of the time....<br>
<br>
I doubt if keys are tight on a piano that's that old, but it's worth a
look. <br>
<br>
Isolate the different functions to check for sluggishness. AFter
awhile you'll be able to diagnose things fairly quickly.<br>

Thanks for all of the great information. <br>
(I also found some stuff in the Technical Exam Source Book.)<br>

I assume she is talking about one of those....... Brooks action is it? I
think the name is something like that.<br>

Drops. I tend to be pretty liberal with my drops - just want to be sure
to get the bushings good and soaked. Just make sure you don't soak the
butt leather off (DAMHIK! - although I wonder, was that worse than the
time I filled all the key pin mortices on a set of keys with water to
soak the bushings out? Wanna know how to plump-up a set of keys?).
Actually, what I do is get my aim calibrated, set the action to where I
have access, and squeeze my squirt bottle (fine tip) and just run a
stream of it right up the whole action in one direction on the butt
centers. Then I squeeze again and run it right across all the butt/flange
centers the other way. I might repeat that. Then I'll target another
action center if needed - check them all - jacks, dampers, etc.<br>

there any other causes I should look for before I try soaking?"<br>

Well, you need to do the standard checks. Isolate the keys from the
action - which one is slow? Remove a couple butts and check flange
friction. Just isolate all the moving parts and you should be able to
identify with confidence exactly where the problem is (or where the
problems are).<br>
<br>
I'll put a fan on when I let them dry overnight - put the fan on low and
not even point it directly at the action. I've had real good luck with
it. Often one application makes the magic work completely. Sometimes it
will only get 80% of the centers and you need to do it again. Even then
sometimes I'll have to Protek a few centers to get them all working.<br>
