[PSUBS-MAILIST] gamma's arm

[Alan via Personal_Submersibles]

Hank,
I investigated the idea of modifying a large ball valve
to make a Q ball manipulator. It seemed doable with the
right type of valve.

I have to admit, it was a bad idea to mount the valve inside the ballast tank area.  A single drop of oil that leaks ends up fogging the windows.  As part of my renovation, I am mounting the arm and valve to a drop mechanism under the front ballast tank along with a thruster package.  The entire assembly including thrusters will be jettisoning.
