[PSUBS-MAILIST] gamma's arm

Vance,
I removed the arm from gamma along with the valve and supporting stuff.  Turns out that package is chunky, 108 lbs.  Mystery solved!  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.
Dan Lance gave me a video to watch called The dry divers, it shows the Q Ball arm in action.  That little arm is quite impressive.  I would like to see the plans for it.  I did not realize it actually used an actual Q ball.
