I've seen an OLD picture of what I think you're talking about before, it's somewhere on this board. It's of some guy and a teenage guy who are putting a cover over the motor. The chopper and stator look just like a short cone pointing up. It looks as if it's designed to try and direct the sound output down instead of straight out, I have no idea what it's called.dilloncarpenter wrote:Soccerdude, have you ever considered a variant of the old sirens with the motor on top, and a cone shaped rotor/stator? That's the best match I can think of.
