Does anyone know where I can get my hands on a drawing/design for a "soft pop" safety valve? I'd like to make some for my Simplex as I'm fedup of having valves that leak till they're tapped with the coal shovel.

Thanks

Del

Hi Derek,

You want the series of articles by Gordon Smith that were published in EIM January, February, March, and April 2001. Polly Models sell the springs for Gordon's design or Lee Springs.
