The basic idea behind [Matthias]’ air raid siren is to make two impellers that force air through two stators along the perimeter of the rotor. He has a lathe; if you watch his shop tour video he mentions that its not used very much, and acts as storage for other under-utilized equipment. I’m thinking one that was powered by a drill motor, or if you wanna go crazy, a motorbike engine. Many of the old municipal air-raid sirens were powered by industrial Chrysler Hemi V8 engines. A modern 4-cylinder engine is probably reasonably comparable power, actually; might be a little lower.
I have said for more than 30 years about electric cars how fun it would be to have the Hemi^R sound for Drivetones^R! What I am assuming is that output power is linear with input power, which may not be a correct assumption. I once saw a video where some kids had a motor scooter tipped on it’s side, wheel against the MGR, spinning it crazy fast. I once disassembled a vacuum cleaner and it had the same style and almost size rotor in it, just made from aluminium instead of wood. Anyway if you got an old vacuum cleaner you could make a siren too I guess, all you need is a motor and rim with holes.
In fact if you strategically made holes in the housing of a working one… instant siren. If you want to make a siren out of a vac just hook up swimming pool drain hose instead of the regular hose.


Small puffs of air would come out of the much larger hose from the reed, making a untuned reed organ pipe. In the 70-80’s they had a toy on TV adverts, a piece of corrugated hose of thin wall molded plastic.
Early 60’s Atlas series NASA found out the hard way (boom) that main fuel flex hoses with wavy insides produced anything but smooth flow.
This Woodsmith Plan is a downloadable PDF file that you save to your computer after you complete your order. This panel only works for cuts when the blade is 90° to the saw table — which accounts for most of the cuts that I make. There’s another large opening found on contractor and benchtop table saws I haven’t mentioned, up until now.
Being the master woodsmith he is, he decided to build a dust collection system out of wood. As the siren spins, the air coming from the impellers is either blocked or passes through the stators, creating an alternating high and low pressure; to be more accurate, it creates a ton of noise. There are a few useful tricks to be picked up from his tutorial, though: balancing everything on a marble really seemed to help with the build. Fingers tend to bounce off a table saw whereas a band will chew right through before you realize. He also mentions that the setup is the most dangerous thing he has done with his table saw.
I have seen it happen to many people, in all sorts of semi-dangerous professions(carpentry, forklift drivers, crane operators).


My father was a carpenter for 15 years and looked away while cutting – bam, lost a finger.
Or even a 4-cylinder car engine, though you’d need a hell of a long wire to the ignition switch.
In the case of the rippled surface hose above the whole mass of air is modulated to move at higher and higher harmonic series, gushing out (or in the vac in) in a much louder manner. Everything worked out in the end, but in creating wooden impellers and blowers, he discovered his creations made a lot of noise. Stack two of these impellers together and you’ve got a two-tone air raid siren made out of wood. I stepped on the switch and almost lost my balance trying to turn it off again, as the harmonic wailing went on.
These handy tips can quickly improve the dust-collection capabilities of your table saw without spending a lot of money. For this project, instead of trying to quiet his blower, he decided to make one as loud as possible in the form of an air raid siren. You can buy an inexpensive plastic hood that rests inside the saw cabinet (Ours came from Rockler).

    Lumber, as the parts will resist dimension and fasten are strong enough to deal with heavier.
