Hello fellow horn and whistle lovers! I have a problem that I hope some of you could help me solve. I am now the proud owner of an operating Hancock 4700 whistle. I have a Pancake compressor supplying the air pressure and a Graham-White horn valve to operate it. When I blow the whistle, the Hancock starts to emit it's beautiful sound, but only at a very, very low stage. Thinking the Pancake was maybe not providing enough air, a friend stopped by with a larger compressor and we experienced the same results. It sounds to me like there is not enough pressure there to allow the whistle to completely sound. I sure would appreciate any assistance, advice, or suggestions any of you may have. Thanks!

Use a 1/2" line instead of 1/4" and no quick connects.

As stated above, you will need at least a 1/2" ID line with no restrictions to blow the 4700. Also a large tank of at least 60 to 80 gallons, as blowing a compressed air whistle is like opening the tank to the atmosphere. No resistance like encountered when blowing a diaphragm airhorn.

Harv,
The correct name is "Dick in a Dish", using "a" instead of "the". Kinda flows better.

BTW, I prefer my dicks "dishless"...4710←model that is without reflector.

I like dicks only if they're paired with atleast one brass bell on an ALCO S series.
