Hello, does anyone know a source where to get an used aermore whistle in good condition for a reasonable price. I want it complete with the pedal etc.
Thanks for all information
The one I had worked fine with air pressure in the shop but was barely audible installed. Don't know if I would fool with another one.
there are different models of Aermore whistles, and the T needs the smallest model, as there' not enough exhaust pressure to blow the larger ones!
I found this out like John did. . .
My Aermore horn tubes measure 4.75, 6.75, 8 and 10 inches. The sound isn't much as idle but with the engine revved up a little it has a nice, full sound. At full throttle and high revs it sounds like the Wabash Cannonball is coming down the road. It's no wonder they were finally outlawed!
The secret (I think) for a loud exhaust horn is to use an exhaust cutout which really cuts the flow of exhaust out through the tailpipe and muffler. Almost all the exhaust is then forced through the whistle. I have seen some reproduction cutouts which simply open the exhaust pipe towards the whistle, but that isn't enough for a good sound.
I was inspired by Dan K's post of his project and made one myself. It was a fun project and after some adjusting, works well. I did buy a factory made cut out valve instead of making my own (although that would be a fun some day project too). I found the foot pedal used and cleaned it up good as new.
Below is a link to the shop photos that show the whistle project and installation. There are some at the first, than photos of other projects, then the rest of the whistle project further down.
Making one was cheaper than buying, and was a real education as well.
Eric Sole is right. The cut out for the whistle has a tongue that swings into the exhaust pipe closing it off so that all the flow is directed through the whistle. I have a whistle cut out in a box of junk around here If I can find it I will post a picture.
Hey John, I stepped out to walk the dogs and realized I hadn't attached the pictures.
There are two pivot points in the cutout valve, the upper shaft in the picture is the through valve which is normally open and directs the exhaust to the tailpipe/muffler.
The lower pivot point is normally closed and keeps the horn OFF.
So basically, whenever either butterfly valve is OPEN, the other is CLOSED.
Below is the horn OFF position.
Below is the horn ON position. This plate blocks the flow to the muffler and gives a lot more pressure to the exhaust horn.
I have a video of the horn sounding while driving the car -when it used to run , but I will have to figure out how to upload it somewhere you all can access it. I'm only a YouTube viewer...
Eric, please download that video on Youtube. I have whistle installed on my Maxwell but don't have it running yet and people are always asking what it sounds like so I'd like to direct them to a video longer than the very short one on Youtube now.
Ok Howard. The toot isn't really very long, it's just applied at a strategic moment! I'll get on it ASAP.
The size of the horn is what makes it loud., we have 2 of them the small one works get when your driving, not so much at low speed so we put the large one on it works at low and high speed sounds like a steam train
I have three of these things - never used. There is some minor variation in construction and size. They also have different tones when I have applied shop air. How does one know what fits a T ?
i have the big aermore on my 26 with the real valve. highway speed, and better yet down hill, is when it sounds nice. idle to mid throttle just about nothing. trying to tune it with air pressure in the shop is deceiving because it will not sound the same from exhaust pressure. fun toy!
Can you provide measurements for a "big aermore" to help me ID what I have ?
Just ran across this on Google. It has the most information on Aermore's I've seen yet.
1920 Aermore advertisment states 15 inch for cars of 30HP and up. 13 inch for cars of 25HP. 11 inch for Ford and other light cars.
Earlier advertisement listed 15" 12" 10" and 8 inch size for motorcycles.
my "big" aeromore has the longest tube at 8 1/2, the shortest is 4". overall length is 11 1/4". so, i guess i dont have the big one, but its the more common size you see. i have always thought about adding a bell reducer to the input pipe to drop the size down from the 1 1/4 od to smaller, say 3/4 od to see if the same volume of air traveling faster would make it work at lower rpm. a T just does not flow enough to make good tone, and at the slower speeds, you can hear it pulsing with each cylinder breathing. so, another idea i've had but not done , would be to add a small tank, like a propane tank to the line and provide a more steady air output. my friend has the same whistle on a model a, and it is loud! even at low speeds
It will be plenty loud if you have the right kind of valve and a good whistle. I just about got run off a tour several years ago because I was passing cars and giving them a little steam whistle as I went by. (well, not really run off, I'm kidding)
If you do it right you can sound just like a railroad steam engine whistling for a crossing. They are LOUD!!. I've got 4 or 5 of them and they all sound different.
Several years ago I had a neighbor that that several wimeriner (sp?) dogs that barked and howled about 23 hours a day. I ran some air lines out of the shop to two steam whistles and an Aermore mounted to the top of the fence. When the dogs started howling I'd pull the chains and blow the whistles -- they were about ten feet from her bedroom window. The lady got the hint. She moved and took the dogs.
I guess I am a steam buff first, as I don't like the pulsed "puffing" of the exhaust driven whistle. I will work a reservoir tank into the mix somewhere to have a good, solid reserve of air when needed.
Funny, but I have had these things for almost a year now and had no idea what their application was ! A guy rolled into the scrap yard where I was offloading some brass and copper and asked my scale guy if they were brass. When the scrap guy blinked, I asked if he'd sell them (along with several steam whistles) and bought them from him before the scrap dude came back. Only in the past few months have I decided to get serious about T ownership and what a surprise !
Burger, if you put it on an 8 cylinder the pulsing is almost undetectable. I held the whistle on the end of the tailpipe of a V8 and it sounded sweet!
WOW, a guy was scrapping STEAM whistles???? Lucky catch--they are starting to become premium! I have some I obtained before the market changed.
Clayton, the line from the engine to the whistle needs to be as open as possible, you won't gain velocity by reducing it; the whistle is relying on back pressure to sound.
When I had my steamboat, I set up an aermore as a steam whistle on an experimental basis. Used a very small valve (1/4") and a short length of 1" pipe as an expansion chamber between the valve and the whistle. Steam expands when released from the pressure vessel, and it worked, reduced the pressure and provided the volume. Sounded sweet!
Stan, You're the greatest!! What a set up!!
OK Howard, I've uploaded the video to YouTube. I hope it works for you at one of these URLs:
This was just after I imported my 1927 Runabout to Spain. My wife and I were driving down from Tibidabo mountain along the antique Blue Tram Car line. As I was passing the Tram, I thought it would be fun to "salute" and I gave the whistle a pull, unintentionally startling the driver (I saw him jump a little). Even so, he returned the salute with a nice clang, clang of the bell.
I found this video of an Aermore which sounds like mine, but with a fuller sound since it's on a Model A moving a little more exhaust through a dedicated outlet just off the manifold.
Thanks Eric, now I can show the neighbors what they are in store for!
A good number of them show up on ebay. Type in "steam whistle" for your search is one way to find them. (and/or Aermore) Look in the All Category section.
I tried the T sized one, rather lack luster in it's report, so I went to the next size up, much better.
I don't think anyone has mentioned that a reproduction is available from Texas T Parts (18750) however read the discussion on the forum back in 2005. http://www.mtfca.com/discus/messages/29/36788.html?1193159962
Perhaps this product could be adapted:
Of course you would need to add an exhaust cut out, maybe this one from Mr Gasket could work:
I had an exhaust whistle with a good valve just the one in Eric Sole's photo.
When tooling down the road that thing really screamed.......
At low speeds it still got attention.
A very pleasant tone without scaring the crap out of people.
I have the exact same cut out as listed above from Mr Gasket but mine was from a place online via ebay for faaarrrrr less money. I remember about 12 bucks.
