- Here i present you my video-documention about a special "mobile air-raid siren" which is already about 30 years old. this is the longest and most informative version of this rare little old military air-raid siren with its details. I hope i can give you a clear picture what are the important parts and how it works!
Have fun to watch this video & enjoy the loud test-phase of it. :-)

It's a baby chrysler air raid siren
Doubles as a leaf blower. - it's like getting two of the most useful household tools in one space saving package!
That is the loudest pressure washer that I have ever seen.
You need to make the engine exhaust quieter, neighbours may complain about noise otherwise ;-)
"Sure"
5:30
Only for the impatient
it was the 1st run of this siren since about 20 years! and it is an 2-stroke-engine, thats normal with the smoke!
That is just awesomely loud!!! Great job :)
interesting-looking lawnmower!
i was more intrested in the motor than the horn, that motor was cool as hell, rare ill bet, ive never saw one like that
sounds like my weed-eater :)
Nette Gerätschaft! Hoffentlich folgt bald ein Video bei maximaler Drehzahl :-)
This video should be even longer!
so, be glad that you've survived the torture!
@robertgift
here in this example the rotor turns in clockwise direction! because if u look from 28-30s, there u can see the inclined positions of the 9 lamellas and they are causing together the best effect for the loudness. because the air will "shoveled" by them through the vents of rotor/stator with the help of the high rotor speed!
almost every siren-rotor is constructed like this one, with the inclined lamellas!
Very nice machine. The air filter & choke resembles a bicycle bell
Awesome video, love the siren great job on the production value of the video.
The engine is an English-made Villiers two-stroke utility engine of 147cc. Villiers made every part which went into these engines with the exception of the carburetor.
Freut mich sehr deinen positiven Kommentar zu lesen. trotz das diese doku auf englischer sprache ist!
also hat sich die mühe diese doku zu erstellen doch gelohnt.
Hi Michel. Congratulations. It is an excellent warning system.
But seeing your master the machines and power tools I ask you:
Why have not you done a clutch system to release the wheel of the engine?
Many electromechanical sirens have this simple system. Also you can do with a rotor that contacts open and centrifugally. So, by not applying force to the wheel, if it is well balanced with its bearings, it will spin for much longer without the motor.
It is a fact that only a few brands have sirens.
The electromechanical Federal Signal siren Q2B we call "Coastal" has it and all fire stations want to have installed on their fire trucks, this siren.
Excellent work.
thats no problem to make that engine electric-startable. (i even have a plan to make this real!) but one the other hand think of the whole weight of this mobile siren: i guess it would be approximately 100 kg! you additionally need a battery (12 V DC) with some amperes!? but it is a great suggestion you did! ;-)
hab da noch einiges vor mit diesem gerät! ich hoffe baldigst dies umsetzen zu können und videos davon zu machen.
This video could easily have been 3 minutes long. Nonetheless, after a lot of scrubbing through the timeline, I was still mildly entertained.
@grandremonef
this special siren was in use as an old military airraid siren some years ago. i only want to show some details of this rare kind. hard to find a functionable one like this.
@silver760
yes, thats right. one piston sealing was broken. and i ordered a new one: it was shipped from there in GB. i was very glad, i´ve found a person who sold such a rare and important part for this villiers-engine! :-)
Very well done!
this mobile siren was basically engineered by a company called DISA. BTW, they even constructed hand sirens & maybe other siren kinds!
a crank siren is just boring. but this rare siren here is a special kind of siren. nobody knows about the existing of it. and besides it is an awesome idea to make such an invention! hats off! and in war situations it is not necessary to ask for waste of time or money!?
u ever noticed how this vid is 9:11 seconds long lol
@e57michel the tube on the petrol cap that you captioned as a dipstick, is for measuring the oil that is added to the fuel for the 2 stroke petroil mix, these Villiers engines were used on all sorts of light agricultural machines and motorbikes too.
i also notice in the note you say it is 30 years old, l think you will find that mid 60's is the youngest it is likely to be and probably 40's-50's
Honestly, I think that the engine is so loud it would make a good siren by itself! :)
That would explain it! Makes sense when you think about it.
Just the motor idling without the siren itself sounds like a beast
wieder mal echt nice video...wollen mehr davon sehen von dem guten stück!
Whow, that's a GREAT video! But when ya gonna take that siren's engine all the way to the top speed? Whow, now that'll cut some ears!
Oh, also, try to find a way to make that engine electric-startable. That'd be cool, too!
"British Seagull" boat engine springs to mind...
I like the idea!
Looks like one of the large leaf blowers i use for fall clean up, Thumbs up nice video
your neighbors must love you
@pinselplins
no, its not a GDR-engine! it is a 2-stroke engine from "Villiers" with 150 ccm!
nice u should put the throtel all the way so we can see how loud it is just a suggestion
it was only a test of this mobile siren, if everthing is ok with the engine and the other important parts of siren. this old siren was activ some years ago. and so i want to run it slowly in the first time. and soon i will try to run this old siren at full speed as many people want to see this.
Sieht aus wie neu das Gerät :-)
Ich finde es toll wenn so alte Technik ihre Liebhaber hat. Irgendwann werd ich mir auch etwas altes kaufen und es wieder zurechtbasteln.
comming soon the full-load of this little and loud treasure! it is too cold for the moment....
Can it blend a smoothie?
My parents own lawnmowers with electric starting, and one of them is a traditional walk-behind size. They even own a string-trimmer with an even smaller starter motor (about 1-1/2" in diameter)!
So you'd obviously need to get a flywheel with matching-sized starter gear teeth on it, and preferably one with a magnet that passes a charger coil that you'd replace the regular coil with (spark and charger combined), so that the engine could keep your starter battery charged.
(Cont.)
my non-binding opinion:
For the sake of completeness: this muffler is also necessary as an important part for the whole assembly of an internal combustion engine like this in the video.
@gislemark79
the silencer is movable and there is a better controlled discharge of the exhaust gases! and besides it prevents the discharging of some oil of the 2-stroke mix during the siren runs. (that is maybe a good explaining!? otherwise it is left to your free imagination!)
@e57michel The 90-degree adapter imparts some resistance to the gasoline engine.
An electric motor could be mounted in any position.
Have you tried turning the rotor in both directions to compare output?
Amazingly efficient rotor/stator.
i´m very happy about this situation! ;-)
@kieranmullen2
sure. but that was the available technology of that time in the middle of 70´ies. it is an oldtimer of a simple & primitive but functionable mobile air raid siren for the military or as you say: weed wacker! ;-)
I would take the siren mower to stationary engine shows.
The engine sounds like a typical 2-stroke engine, but why it has silencer?
If not for that charger coil that the flywheel magnet rides right under (or some other kind of generator like a small alternator or something like that), then you'd just have to charge the starter battery manually (which you could probably do after you had gotten back into the air-raid shelter, especially with a detachable battery).
there were no people in the near of few kilometers during test-phase of this siren.
and so there were no complaints about an unofficially & private siren-test!
but you dont have to exaggerate such "siren-tests"! ;-)
that is an easy reason:
in case of attack if you lie in the trenches and from there you have a safety position to operate the siren by the longer cable to warn your other companions.
the little crank one sounds better and more like an air raid siren.....the motor one just sounds like a drone
ursprünglich wollte ich diese doku erst auf deutsch schreiben, aber habe mich dann für die englische version entschieden für unsere internationalen sirenenfreunde/interessenten. aber eine deutsche ausgabe dieses videos kommt auch noch, nur geduld! ;-)
is there a video that shows the thing on full power?
your amazing
very nice did you make the siren part?
Is there a mixture control, its sounds like its runnign a bit rich, ie +fuel -oxygen, perhaps there is a needle valve to adjust this?
Sounds very good by the way.
heh kind of like a siren attached to my lawnboy! you can hear a slight waver in the siren from the 2 stroke engine.
OK It's loud but how well does it cut the lawn?
tolles video! Bisschen lang, aber man schaut's irgendwie doch gerne bis zum Ende an^^
aber sag mir bitteeee, dass du Gehörschutz getragen hast! :D
bis zu 129dB sind ja kein Zuckerschlecken, insbesondere aus nächster Nähe.
.. is the muffler on the engine really that necessary?
@SeafireTWA
someone asked the same question yesterday:
this song was created by myself one year ago and the song´s name is: "The Rising Moon, by E57Michel". :-)
Can i buy this standing think????
Is this british made with a villiers engine? Also did you know the cup on the bottom of the fuel cap is for measuring the two stroke oil when filling the tank,it should say how many cup fulls to the gallon/tank on it.
Hello e57michel my name is Tobias Rabelink 22 years i have a question
Can you take a look at this video from brining it to the net because i want to know
What kind of siren is this And Can you give me Some information
About it
Starts up great! Was it a cold start?
sounds like a mad pencel sharpener
@Psychlas
die ist aus den 70´iger jahren vermutlich. aber funktioniert wie am ersten tag, hat mich sehr viel zeit und mühe gekostet das baby soweit wieder von häßlicher tarnfarbe alá millitär in ein schönes ansehnliches feuerwehr-rot auf vordermann zu bringen. :-)
aber manche raffen es net, dass es sich hierbei um ein verdammt seltenes, noch funktionierendes schätzchen handelt. hat schon einen gewissen sammler-wert.
good job
only visible for short time, but it is the same siren-construction. nice....
epic
@cameraguy38
This was my own composition of this awful music. And so i´m a little bit proud of the whole own-made video. And that´s my aim to make such videos with the same style for the future. I can´t hit everybodys taste for "good" music! (Sorry for this!) But i´ ve to accept your opinion. I can live with it. :-)
@6V92TA
i made the whole video inclusiv the background music. i don´t know any other American porta-sirens, sorry.
The engine makes the siren chatter
It has such a huge muffler for something that is intended to make a ton of noise anyways.
autumn is already over!
sicherlich wäre ein motorradgas-griff ergonomischer, aber dieser "plumpe" gashebel tuts auch! ;-)
cool
@e57michel can't wait : )
yeah! :-)
it cut off just as he began to crank the engine... or ignite it? i dont know the technical term. where is the rest?
thx
@e57michel sure will. but then again, will you let me know if you have 1? please..
This looks to have a throttle cable that is much longer than it should be, why is that?
@SeafireTWA
hab noch vor ne längere version davon zu komponieren. aber es fehlt an zeit dafür.
You built it by scratch or did you take apart some other airraid siren and built this one?
kannst du den song evtl mal in youtube hochladen oder so ?? der is der hammer !!!
@orthografe
i think, this siren won´t getting louder, if i use it over 50%!
unfortunately, the sound level measurement only goes to maximum of 130 dB and not more! :-/
where can i get one of those hand crank sirens at 5:33???????
@robertgift
you can run the rotor/stator-unit seperately: in horizontal position with an electro-engine of a washing-machine. i only need an adapter for the power transmission from engine to rotor! but thats no problem. (thats an old idea of me) ;-)
hast du die auch restauriert? wenn ja, wie lang hats gedauert und wie sah die vorher aus?
@princenoah21
very good explanation for the 62 poor ratings! ;-)
Was ist das für eine Sirene am Motor? Nach e57 sieht die ja nicht aus. Wo macht ihr eigentlich solche Testläufe? Da muss man ja irgendwo auf einem acker stehen- weit weg von dem nächsten dorf. Also ich bin begeistert. Die will ich haben.
@MishuTaste
This siren is (was) intended only for the military sector!
what is the fascination by loud noise
@OperativePlum
diesen satz kenne ich irgendwo her!
@RundownJet
if you are lucky, then try it on a flea market to get one for yourself!
Just stick a large waveguide onto the exhaust of that engine lol ;p
