Real whistles aren’t made by just cutting a curved notch in a round object though… Borrowed this picture from Jose on the hornwhistleboard just for illustration… http://www.hornwhistleboard.com/download.php?id=2346&f=3
You could cut out metal sheet with a hole in it, weld it in your flowmasters pipe and kablam you’ve got your self some whistle tips. Whoo Whooooooo
I found train whistles @ a local truck stop or at least a knock off. They look to be quality made and are very heavy, chrome or copper color. Will post a pic when I get it.
you can live in a town with a 200 IQ and the news will find that one guy passing by with a IQ of 25
