[PSUBS-MAILIST] gamma's arm

Alan,
I agree, except you would not have the full range of a true Q ball arm.  You would have total range from side to side but not up and down.  I was genuinely amazed at how well the operator worked that thing.  They were picking up items on the fly!

 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.

 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.

 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.
