of the air actuator again. I don't recall seeing any such thing =
(I've caught
a few legitimate emails that were filtered out by my spam filter - =
I've even
seen a few of my own get filtered out!). I would sure appreciate any =
such
info. Always looking for a way to minimize damage to a soundboard =

newbie to
the list I haven't thought to keep copies. Basically a firestone =
actuator is a
length of reinforced hose about 3-4 inches wide when flat, 3 foot =
long, with
an NPT thread tap and metal clip bars on each end. Old firehose is =
thought
unsuitable for this pressure BTW.<BR>I block three of these under the =
board at
spine, belly, and back curve and connect them in series to a SENSITIVE =
regulator. The usual air tool reg. is not fine control enough, =
diaphragm
should be 2 inch or more. Once set I air up and start another job, =
jiggering
the air up a slow notch at a time as I pass by the piano. eventually =
the board
pops out. I really like machine/methods that work while I'm doing =
something
else. If you do some cutting on the end clips. the profile is 1-1/14 =
inch and
will slip in the tightest spaces between rib and brace. I'm a longtime =
veteran
of the industrial auction circuit in Michigan, and lots of automotive =
plant
OEM stuff comes my way, whence these actuators. If I was building one =
the hose
would be easy, not so the tap. One of these blowing out or up could be =
VERY
dangerous to piano and technician alike. Hope this helps. BTW =
firestone also
makes an air spring (basically a tire looking like an elephants trunk) =
and I
have seen these incorrectly referred to as actuators. Accept no
substitutes.<BR>Glenn C.</FONT><FONT face=Geneva color=#000000 =
