--I'm slowly working out the intricacies of tooting whistles. I'vefound that they're easy to toot on just a few psi of air from the ass end ofa vacuum cleaner; i.e. a HVLP source. But if I attach a whistle to amanifold and use a solenoid valve to turn it on and off I need as much as80psi to get the same effect from the whistle. This leads me to believe thateither the narrow passages in the valve is behaving like a flow restrictoror the narrow passage where an air hose is connected to the manifold is theproblem. Can't do anything about the valve but I could add a tee betweenmanifold and valve and add a second or third source of air from thecompressor. --Anywayyyy I'd be interested in hearing from anyone who's beenthere, done that. Suggestions welcome.
