Vance,
You're welcome to speak, but a white paper (with diagrams and illustrations) or photo journal would work best for getting the info out to the masses. Using your camera to document each step in construction would be best.
Is your design similar to automotive engine valves where they seal at the top? Or is the seal on the internal side of the MBT? It seems like the spring compression value for keeping the valve closed will be important. Am I correct that generally, you'd want a standing spring force equal to or exceeding the psi at maximum depth reached? How did you calculate the strength of the spring you need for the valve?
