Test Air raid siren



After testing the air raid siren in the workshop I wanted to try it outside.  With a speed of  over  7000 rpm it is very loud. This is a project  I would like to keep and since I  have so many wood projects on my shelf  thought I would  paint this one.   


                 

What better colour than red for a siren. I took it off the grinder and spray painted the whole siren. I gave it a few light coats, and after each coat was dry I had to turn the rotor slightly to make sure everything got covered with paint. 


The siren is so easy to put together and take apart. It is all put together with the bolt and locking nut. To see how it was made check out the last article  the  siren build.








I showed it to a few neighbors and they did not mind the sound but for a better test I will go to the country which is about ten minutes from my house.  Where I live there are many places to try it and I don't have to drive far.  


     

                   





Here we are in the country on a beautiful day. Shannon is going to try the siren while Mackayla is busy on her phone probably trying to get wifi.


We tested a few different spots and  were amazed at the sound. One spot we tried was 1/2 a kilometer away and  it worked fine.  We all had fun and am sure we will find many new ways to test it.

This turned out to be a great project, it worked out so well and was so easy to make.  I am sure I will use it for halloween.
