Small Red Siren

Wed Nov 18, 2015 10:04 am

I have this small red siren in a container. Just recently, I decided to try and run it, but I found out that the motor was stiff. It would not turn and only hummed. I don't need any advice on how to fix it, I already know how. I won't be repairing it until we actually need it. Anyway, here are the links to pictures (Pic size is 4608x3456, it will appear extremely oversized in the forums)

Hate these poor quality Chinese sirens, reminds me of the Lion King sirens

I love Yamaha Music Sirens.

Its a cheap siren anyway :P But I don't know what to say.. but hey, "poor quality siren's chopper vanes" well... They are a HECK of a lot better then my home made chopper made from cutting the end off a PVC pipe, and then chopping off 5 ports on bottom, and 6 ports on top. :P But what do you mean by the motor is "stiff"

Also, welcome to the forums, Jake_7367! :innocent:

Thanks for the welcome.

I tried to turn the rotor but it was significantly hard to turn. That's what I mean when I said that the motor is stiff.

I agree that this siren is still better than a home-made siren, but there is a possibility of 3D printing a siren.

People have done that before. While it is possible, it's very difficult. Unless you use 100% fill when it's printed (a huge waste of expensive filament), it'll be almost impossible to balance it properly due to how printers layer and fill an object.
