here after over thirty years working on pipe organs and regular =
maintenance of
blowers and rectifiers. Please Insist that your customer find a =
good pipe
organ technician. I have come upon blowers that were 80-90 years =
old and
not serviced in decades. The motors often need attention. =
You
as a piano tech are not prepared to listen and look at the motor to =
discover that the motor will need replacement or major rebuild. =
Without
correct regular service by someone accustomed to working on old organ =
blowers
and their motors, this motor could literally destroy itself and =
everything in
the room around it. I have seen heavy metal thrown through =
concrete
walls. These motors are often half horse up to 7 or 8 horsepower, =
the size
of Volkswagen, and are running at thousands of RPM. A minor wobble =
from a
worn motor bearing can cause spontaneous explosion of the huge blower =
and motor
as it wobbles itself apart at warp speed.</FONT></SPAN></DIV>

last Christmas they were preparing for the big musical special at a =
Presbyterian
church that had not had a tech for several years. It had =
drastically
lowered in pressure for the whole organ and the blower was making a =
noise.
They somehow got my number for the first time. I got there to find =
the
blower blowing a shower of sparks out into the room and it would not get =
up to
speed. I immediately called my local specialty motor experts who =
rebuild
all my Ampico and Duo Art motors and they came and got it. After a =
thousand dollars it purrs like a kitten. The interior starting =
windings
had been about to burn out since it could no longer click out of start =
mode to
get to full speed and it needed a couple of new bearings made for =
it. Any
longer and it would have destroyed the motor beyond repair. =
Replacement of
this large blower would be about $10,000. but $1,000 got it going for =
another
fifty years.</FONT></SPAN></DIV>

<DIV><SPAN class=750152803-10072004><FONT face=Arial color=#0000ff =

point is find a pipe organ expert to check out the blower on ANY pipe
organ. A pipe organ man must be a acoustical expert, a heating and =
cooling
man, a sheet metal worker, a plumber, a woodworker, an electronics =
engineer, a
motor expert, a refinisher, an expert in antiquated pneumatic systems, =
very
similar to player piano systems, an expert in antique electrical =
systems, and a
tuner.</FONT></SPAN></DIV>

<DIV><FONT size=2>I have a new customer, a church, whose pastor says =
they also
have an organ that needs lubrication. I don't know anything =
about them
(haven't been there yet), and don't want to mess with something I =
don't know,
but they make it sound like a fairly routine operation. Is it =
something
like lubing the blower motor? Is this something I should =
attempt, or (my
preference) leave to the experts? How would I find an organ =
maintenance
person? I'm assuming it's not electronic... </FONT></DIV>
