In this tutorial I show how to make an air raid siren using a standard bench grinder bought from amazon and plywood, its howl is quite loud but not so loud the neighbours complain
Bench grinder used was an Einhell TH-BG 150 and can be found here goo.gl/O9cCiP

Why the dislikes? Give the guy a break, he did a great job. Try doing yours if you think you can do better instead of disliking.

@alexandersalarms5380 5 лет назад

Nice! You managed to make it sound like the original carter siren! Probably cause of the port ratios, awesome!

@Omegadoomship 5 лет назад

Impressive. I would have used a different port size so it would be more high pitched. Either way, using a bench grinder for that is total genius.

@86FxBdyCpe 3 года назад

Agreed, wrong pitch.

@oneofmanyparadoxfans5447 3 года назад

@@86FxBdyCpe It is a little low for a siren, but it does sound like a V-twin revving, which is cool.

@dank980 2 года назад

@@ChrisVTitus it’s spinning 2850, the europe standard so it’s at the right RPM but it needs double the port ratio to sound better. 8/12 instead of 4/6.

@fadedcametowasted9647 4 года назад

No the vibration frequency sounds more like a weedeater the frequency is too low therefor too low pitch so it wouldnt sound sålike an råairraid siren so it wouldnt five them flashbacks

@fadedcametowasted9647 4 года назад

Are you familiar with how noise works (frequency = pitch) (pressure = higher decibal) decibal being “loudness”

I've been looking into some how to make tornado siren videos for a project to do with my little brother. He and i are obsessed with sirens and i made a promise to him once I'd have the money to, we'd make one together. We may start off small because he's very young but so far once he's older to understand measurements I'm more than likely gonna use this tutorial for our bigger siren project

@halpmeamcringe1538 3 года назад

@leksey7870 6 лет назад

@Subgunman 4 года назад

That is an excellent project!!! There is one issue however, its the motor. It does not have enough torque to pull the needed air through the siren. I have basically the same grinder from Lidl and it does to have the power to do grinding. Try covering one side of the air intake and see if the tone on the remaining side increases. If so it shows that the motor lacks the power to pull the air through properly. Think I might do one of these as well. Alway nice to prank someone.

@AintBigAintClever 2 года назад

@@projectmayhemUK or do a Colin Furze and gear it up. A kids' pedal tricycle flipped upside down might give you everything you need if you can replace the pedals with a drive plate attached to the grinder. Another option: out with the bench grinder, in with a pair of angle grinders, but they might be a bit too torquey and just wreck the rotor. You'd definitely want a guard on them :D
