I made a steam chime whistle recently to use on our canal cruiser. It is based
on a model steam loco one I was lent, I tripled the scale & works fine,
deafening on 100 psi air, on the boat it is run off an air horn compressor
around 25 psi, just loud enough on a quiate canal. you are welcome to the plans
if you have autocad, or I could convert to a word doc. format or possibly a
jpeg. Whistle stands about 5 inch high - obviously you could scale it.
Mail me if of any interest.
Hi there just4fun, It took some finding, but see if you can get hold
of a copy of the U.K. publication "Model Engineer" Vol. 188 No. 4167,
April/May 2002. Page 234. One day I intend to make one, still trying
to think of an easy way to get 80 to 100 psi in a car. With 2
alternators, aircon., power steering & the radiator fan I've run out
of room up front, thinking of going electric with small
receiver,solenoid valve, presure switch & safety valve. ALL worthwile

Guy Lautard's, "Machinist's Second Bedside Reader" contains plans for a
replica Lunkenheimer Steam Whistle. It works fine on air. I made several
out of polished brass mounted on walnut bases for gifts. Very loud on 100
psi air, but the pitch is high because of the small size. However, it can
be easily be made larger.

Piece of cake! Go to an auto salvage yard and buy an air compressor that GM
cars have that have the ride control system. they can be had for less than
US$20, especially if you remove it yourself, which takes only a few minutes.
Many of the '90's have it, Buick, Oldsmobile, Cadillac, maybe even Chev and
Pontiac. Ford also used something similar. I use one for the air horns in
my 1 ton Dodge truck. You'll find that the GM compressors cut out at
roughly 120 PSI, but by removing the head and fly cutting the surface of the
block by .045" you can effectively raise the output pressure to around 180
PSI, and the compressor doesn't appear to have any trouble with the higher
pressure. I run my air system up to 150 PSI. The pressure switch turns on
at 135. You can buy it at RV supply houses that sell Hadley air horns and
parts. It is threaded 1/8" tapered pipe. For an air tank, go to a semi
salvage yard. You can find them anywhere from a few inches in diameter up
to a foot in diameter, and they're usually quite reasonably priced.
One of Guy Lautard's Bedside Readers has dimensioned plans for one in
it, he also has a little on how to scale it up or down. Don't
remember which of the three has it in, though, although all three
books are well worth having. Enco runs these on sale occasionally,
plus he has a web site you can order them from.
Over here lots of cars used to have "automatic load leveling systems"
which used special rear shock absorbers with air bladders in them which
did the requisite jacking up when you were carrying a couple of dead
bodies or something else heavy in the trunk. (Some cars used greatly
geared down motors to twist the fixed ends of torsion bar rear springs
to achieve the same result.)
I've still got one of the old 12 volt dc single cylinder compressors
from one of those air systems kicking around, you're welcome to it, but
the freight would probably make you moan louder than the whistle you
want to make.
Perhaps you can find something similar at a wreckers?
Even more years ago I had an vacuum powered air compressor kicking
around rescued from some some automotive use It had a vacuum diapram
about 6 inches in diameter which got shuttled back and forth by a
toggling valve. It drove a small bore compressor piston. I can't
remember what system those were used for, anyone recall?
As a kid, I bought a "wolf whistle" for my car. It was a siren like
device which worked on vacuum, not compressed air. You pulled on a cable
fed through a hole in the firewall to operate its valve. It was pretty
darned loud too, and I never figured out why the sound didn't all get
sucked into the engine.
Thanks for the memories,
Yep, I sure do. I used one too, until I bought my '99 Dodge 1 ton with the
Cummins engine. The compressor of which you speak is made, or at least sold
by, Hadley. As far as I know they still offer it. They used to have
an exchange program whereby you'd submit your old one when it finally
decided to quit working, and they'd send another in its place for very
little money. Changes in design and outrages prices on everything these
days made that program short lived. I managed to get in on it once, but
only once. By the way, the pressure side of the compressor is actually
compound. There's a large low pressure cylinder on one side and a small
high pressure cylinder on the other. They're actually a nice little
compressor when they work well. Mine would build over 100 PSI pressure
when new, but it slowly falls off with age until the compressor just quits

Having just looked them up on the Web, it's the Machinist's Second
Bedside Reader which has the steam whistle plans. It's too bad we
can't find used copies of those for $5 like we do the Machinery's
CAUTION: Do not use remaining fingers as pushsticks!
Consider: Put the whistle assembly (two or three tone) in a dragon's
head hood ornament. Power the whistle with propane from one of those
plumber's torch type tanks. Install an electric igniter in the dragon's
mouth. Fire breathing screech! :-)
Only if you consider the loss of fine detail where lines
intersect -- especially at angles -- to be "without problems". Most
systems have available viewers for .gif, .tif, and other lossless image
formats -- including .png.
Hi guy's, thanks for the aircompressor idea's, I'm not sure that
ride levelling is used down here, but will ring car wreckers tomorrow.
I drive a long wheel base F-100, so the flaming dragon sounds great.
Can't imagine the cops would be impressed. BTW for people looking for
something to make, I can recommend the "Turners square/cube" It's in
Guy Lautard's 3rd. reader. Have fun, Ian S. Down Under.
