use of SAT's and Whippen flange springs

[Larry Fisher]

RE: Use of SAT's on pianners

I used on once to prop up the instrument so that I could get a clamp under
the filler block betwixt the back posts.  It worked most goodestly and I
dint even have to plug it in.  I did turn it on however to give the clamping
job that 90's effect with spinning lights and stuff.  Real yuppie looking.

RE: Whippen flange springs

I have had, on more than one occasion, found the action on some Asian made
pianos to be heavy.  Measuring the down weight I found a smatteriing of
almost always more than 60 grams.  Regulating, easing the keys, repinning
hammer flanges, whippen flanges, tefloning knuckles and regulating buttons,
and polishing the capstans and lubing the whippen cushions all had very
little effect on reaching the goal of 52 grams down weight.  Not wanting to
reweight the keys or in other ways re-engineer the keyboard, I had to come
up with a solution that was cost effective and quick. (customer's #1 and #2
requests)  The whippen flanges had small springs on them hooked through a
loop.  Unhooking the springs and tipping up reveals the short piece of
spring opposite the hooked end.  Using a screw driver or some other
appropriate tool, hold this short piece firmly down to restrict it's
movement, then pull up on the hooked end of the spring increasing the
spring's strength on the whippen flange.  I did this on an entire set moving
the gram weight along as I went and was able to get a really nice feel to
the keyboard when I was through.
