Long Shot, The back alley bomber.

People everywhere duck and cover at the sound of the air raid siren's scream.

I'm finished!!! Had to work through all day today but I did it! It's done!

I ended up gutting the siren and mounting a electric motor from a model airplane inside. When you pull the hand lever it spins like mad and really sounds like a slightly higher pitched version of an air raid siren. The rechargeable battery is hidden in the tank.

I looked everywhere for rivets, once I found the ones I wanted I tested it on a scrap piece of metal. I'm glad I did. It looked horrible. So I decided not to use them. I'm really glad I waited to test it first. If I hadn't I would have had 100 holes in the tank with nothing to fill em but these hideous rivets.








 
Awesome! Does the siren really work off airflow? I got ones that just run off the wheel. GReat job!!
No it won't work off of just airflow. There is a electric airplane motor inside the siren housing. I gutted the siren, took it to the work (machine shop) and cut off the shaft that runs through the back of the siren to the wheel rubby thingy. Then I threaded the back of the finned siren piece and mounted a small electric airplane motor inside. When I pull the handbrake it turns on, when I pull again it turns off. The propeller is just on a pin so it spin when i ride. It's not connected to the motor or the sirens moving parts.
