Old Q2 Rebuilt

This is a Q that has not run in 40+ years. I had the rotor, stator housing and clutch assembly but everything else has been collected over this last year. Here it is in the "nude", without grill and motor cover on its first test run.

[@Henry455]

No, I think the curved blades were an attempt to draw more air thru the siren. Look at the blades on a turbocharger compressor wheel to see what I am saying. The coast time is determined by the condition of the rotor bearing, the balance of the rotor and correct clutch disengagement. If you were to block the airflow to the siren it would coast for a very long time. Look at my "B&M S8B Siren Restoration" video to see what happens when you block the air intake.

[@leemilica]

That's one fast windup.

[@chessbox4776]

high voltage.

[@PapaBearApproved]

what about hurricane 130 mkII? it also has a fast windup.

[@ivansheppard7431]

Not to mention the current draw...

[@davidwhitefancollector3985]

That sounded like a really high pitch STH 10

[@SmoothCanoes]

That motor has some torque!!

[@gunnerjohnson4103]

Looks like a jet turbine

[@ghostamos1201]

Gunner Johnson lol

[@DarkstalkerThePrimagen]

Gunner Johnson off a ge90 cfm leap jet engine without the spinner swirl.

[@kerryalford1492]

True

[@nilo8642]

Plot twist: they removed that from a jt3d lmao

[@IntelligentHorseworldofrandom]

Firetruck siren! 🚒 Thank you for our firefighters!

[@skunko144]

even tho its is so old i would have to say the old sirens kill the new electronic ones and this is really loud

[@CazicTheProtogen]

Agreed

[@ebblue81]

I Picked up 2 Q1 siren's today and I am going to hopefully repair and bring them back to life.

[@dvdmpcd]

The Q is the greatest! Couple that with a an old Detroid Diesel and I can't think of a better sounding combo!

[@frederickglass1583]

So what? Do all firetrucks just have miniature Q2s mounted on them? because this sounds spot on to the sirens found on most hook and ladders

[@tventrca]

Frederick Glass this is the same siren just with the cover off

[@frederickglass1583]

ooooohhh

[@onekingeighteen1k183]

Frederick Glass your right it does sound like one

[@rexius775]

yup kzbin.info/www/bejne/bpTChZmsjraGjrc

[@valhalla7941]

Frederick Glass I’m not sure you’re familiar with how fast those things soin

[@graythewolf6096]

Beautiful spiral in the chopper fan. I call them chopper fans because they are what force the air through the chopper. Idk what they are really called tho.

[@Eights_Coronel-864]

Sorry if I came 4 years later, but what the chopper has around is called "Stator"

[@Henry455]

The M30 has a smaller dia. rotor but Sterling elected to add mass to the aluminum rotor by riveting a steel plate on the face of the rotor and use the term "free rolling" in the Model description.

[@riaanackerman6372]

Your neighbours must love you...

[@philipperiopel1911]

Now that's a real fire truck siren!

[@jaythesprout]

FIDGET SPINNER CONFIRMED

[@ThomasFarquhar2]

Onward oh no you fucking didn’t

[@911caddy]

I enjoyed this one too!! Keep them comin'

[@DarkstalkerThePrimagen]

That rotor looks like a centrifugal pump impeller

[@SecretAgentXD1]

EBugatti13 builders does about the same thing

[@Rtzee]

Very nice!! Love the Q2!! Thanks

[@Siren1000T1]

So that's what the old fire trucks had. I noticed that the holes on the side reminds me of Air Raid Sirens like Castle Castings for example or Carters. I also like how the blade looks too. :)

[@user-xg8yy7yl1d]

reminds me of vintage police siren sound effects in old movies. Like some 50s or 60s movie about 20s mobsters

[@Henry455]

Yes you could. Back in the late 1950's thru 1970's, before the electronic siren became easily available, you could see these Q's and other mechanical sirens used on many type of vehicles including cars. Search on KZbin for "Jeep Q Siren" and you will see it is not a problem.

[@Heyde1979]

winds down nice and slow good job

[@Henry455]

I use the 2 8D batteries because they are available to me, by no means are they required. Most automobile batteries can furnish 600-1000 CCA (cold cranking amps) for short periods of time. In this video it is powered for approx. 5.5 seconds, in my other Q video, 14 seconds, a regular car battery would give many minutes of noise.

[@isaackwon2030]

I also rescued annabella truskowski with this loud fire engine siren in the 1969 tv show sesame street

[@Henry455]

Yes, Q's have been in production for over 60 years with minor changes and new ones are available from Federal.

[@MegaMantim]

When I was a rookie I noticed numbers on the fins of the Q siren...When asked about it the Shift Commander told me the old Guys would play Routlette...Thats when there was EMS and more down time I guess...

[@Henry455]

I have access to a portable arrow board warning sign like you see on highway construction sites. It has 2 8D 12 volt batterys in parallel that I use as a power source, but any 12 volt automobile battery would give several minutes of run time.

[@SamZarifYT]

Sounds like a fire truck siren

[@DDFJ1230]

SamZarifYT because it IS a firetruck siren. Just doesnt have the covers on it in the video

[@SamZarifYT]

Oooh

[@SamZarifYT]

I’m so dumb

[@dylxnchn]

SamZarifYT cause it is

[@Chief176]

The new ones sure dont coast that long, and its really aggravating to me!

[@fcv2169]

Simplemente, espectacular

[@michaelbeiler7164]

Sounds like a emergency vehicle siren

[@chessbox4776]

thats what it is essentially. most fire trucks use these.

[@michaelbeiler7164]

revsta I did not know that

[@chessbox4776]

yeah heres a few pics of fire trucks i just saw on google, that had the same siren. imgur.com/a/9cd8YOI

[@FirstNameLastName-bc2eg]

more like f1 engine.

[@heatseekerbus]

What a screamer! 👍

[@aidanhess5864]

I love the q. I think it's the same in fs19 fire trucks besides a little shorter and a little edits to the sound

[@Henry455]

Watch the video of my Sterling M30, it is direct coupled with no clutch, the coast time is considerably shorter than a clutch equipped siren. The motor brushes have high spring pressure because of the large current draw which creates drag.

[@pxthfinder6201]

Oh man; they've kept that design for over 40 years?

[@SirenGarage]

Nice Job Sounds Great Too

[@Henry455]

Momentary surge of 200+ amps, running 100 amps.

[@AbdulGhani-rc8ve]

I love it

[@joyatilano8546]

u could use this for air raid warning/tornado warning/nuclear warning its pretty cool

[@brianalexi]

If I sticked my fingers in that fan part of the Mechanical Siren then my fingers would get Chopped off.

[@shadowfromsparksnv3253]

Hey send some advice to all emergency vehicles to add louder vintage rotor sirens to their vehicles

[@paytonstory6352]

Most fire trucks do have these

[@jessiedotson1557]

years back I was on a volunteer rescue squad it was an old van type ambulance and we had one of those mounted on the roof now we did have a 200w electronic sign but nothing would get the traffic out of the way like that big beast of a siren we also had it on another truck and the knob on a code 3 run fell off the electronic siren so we had to run that big beast we're traffic pulled over for 2 miles in front of us nice straight shot no traffic whatsoever everybody was getting up on the curb

[@robertgift]

These are too heavy and bulky and draw too much electricity at start-up.

[@Rtzee]

Sweet! And nice collection by the way. Thanks for sharing!!

[@GabesElectronics]

why does that chopper spin so fast on the start up?

[@robertgift]

Excellent! I like it better without the cover. Probably a little louder without the grill and stator port ribs. Federal's rotor is a work of art. Should not be hidden. I would paint an inward spiral on the rotor fins. (A paint which could be removed if desired.) Have you tried reversing polarity and spinning it the opposite direction? Nice, sharp, steady video. Thank you.

[@Henry455]

The design of the rotor clutch will not allow reverse rotation. Motor would spin but rotor would not.

[@Henry455]

@cc10266 The Q sirens have 14 ports.

[@PlatinumEagleStudios]

Question. Do the blades inside the rotor have to be curved to help with the long wind down?? I know the clutch in their or disconnects the motor from the motor and the rotor spins freely, but do the curved rotor blades help?? Nice siren by the way.

[@robertgift]

Oh. Forgot about the clutch. Thanks. What if you defeated the clutch? Would the motor slow the rotor noticeably faster? Still, in use, no need to keep the motor spinning directly coupled to the rotor and wearing the motor brushes. Thank you.

[@transporteymadereraelsolit7491]

Que hermosa sirena muy bonito

[@robertgift]

Understood. Always wanted to know. But does the M30 rotor have smaller diameter and less "inertial mass" so that it slows faster, anyway? Though I have replaced starter motors, I don't recall ever trying to turn one to discern the drag. I didn't know there was more pressure on high amperage brushes. Thank you.

[@jamesquickjr4851]

such a beautiful sound.. what model is this unit

[@Henry455]

Federal Q2A, no brake. This is an vintage model using the discontinued ball & ramp clutch.

[@davidwhitefancollector3985]

That sounds way higher than the Federal Signal STH-10

[@Lambolover303]

that looks like a plane engine tbh

[@reaper2857]

1:09 Bro There's a fire Here Come one Quick

[@alanwatts8239]

1:10 when i put it on her other ring

[@brianalexi]

Well, Your right.

[@rykember11]

Don't stick your finger in there..........

[@CazicTheProtogen]

Stick your head in!

[@45llamas]

go back and forth with the arrows in ur keyboard and make ur own melody

[@robertgift]

I would reverse the DC to make the rotor spin in the opposite direction. Would be.tter withalf the ports. Lower frequencies travel further and penetrate vehicles better.

[@Henry455]

Cannot reverse a series wound starter motor without major modifications. Simply swapping pos. and neg. leads will not work. Also the clutch would never engage the rotor but it would be an interesting experiment.

[@twmax4137]

i noticed that the motor shaft doesn't spin unless you give it power but the rotor rotates and no motor is turning

[@Henry455]

Thats the clutch working as it should. The higher end sirens from most companys sold coaster sirens that incorporated a clutch. When power was removed, the rotor continued to coast, producing sound and saving on electrical

[@dcentral]

123 decibels at 10 feet is how many watts of power from this siren?

[@sergiofreitas9368]

Great thing about rotary sirens is they don't waste a lot of power revving up, and no power at all revving down, yet they still make sound when revving down, so it's really a win-win

[@Dutychief]

Where can I get a replacement siren break? The siren I have has a worn shoe I guess? I need to replace it and put it back together.

[@Henry455]

Go to Federal Signal website, look up the Q siren, download exploded parts list for your model siren, select brake parts you need, jot down part number and order thru a Federal Signal distributor.

[@gertjanvanwouw3434]

The bell at firefighter school

[@beasst94]

they draw a lot of power? how much- approx?

[@user-gh5dp6zw3e]

Q cuesta o en donde se lo puede conseguir

[@Henry455]

See my "Rebuilt Q2 with Covers" video to see it wound up.

[@cc10266]

How many ports are there on the siren?

[@typicaloomp3802]

nice

[@LG_19953]
