Rotatiller siren

[thunderbeam63]

Would it be possible to take a rotatiller and take the rotor out, then make two stators and two rotors, kick it up to 15000 RPM and get a sound?

just thought I'd ask.

[CABLEVision]

It would be kind hard due to the way the tiller tranny is geared although you could get a slow sound out of it. Not to mention how the splines are mounted.

[JasonC]

Maybe, but it would be extremely inefficient.

[Thunderbolt 612]

Not only inefficient, but also dangerous at 15,000 RPM!

You would be better off trying that idea on a old bench grinder.

I say, you should get a motor. make a stator. and then get a circular (it HAS to be circular. i think) piece of metal,cut 5 holes (if wanted single tone) or 5 holes on top and 4 holes on bottom (if wanted dual tone) and make holes (the same way) on a smaller peice of metal and stick it inside.
(attached to the motor, of course) Turn the motor on and see what happens. If you wanna make a better one then I probably desrcibed. go to civildefencemuseum.com and see Eric's "Mini Thunderbolt Project"

I don't know of a soul on this board that doesn't know of the Mini-T. It's one of the finest bits of engineering I've ever seen. (Or heard in person!)
