[PSUBS-MAILIST] q ball arm

[Brian Cox via Personal_Submersibles]

Hank,
        Do you have the original cue ball / arm that was made for Gamma a long time ago?

Alan,
Thanks'
So far this morning I have pressure tested the valve with the cue ball in it and it was fine.  I went to 500 psi, that is all the air I had on hand.  I have one end of the valve machined so it can bolt onto the original cover plate.  I should be working on my cart but this is more fun.  The cart is driving under its own power now.

 made a big discovery. A cue ball arm can be made very easily
 with a 1 1/4 ss ball valve and a 1 1/8 dia cue ball.  I
 removed the ss ball from the valve, just to check it out and
 found the ball is .004 in smaller than the cue ball.  I am
 going to assemble the valve with the cue ball in it and
 pressure test it.  If it works, I will machine the valve
 ends so the cue ball arm has maximum range of motion.

 Gamma has requires some extremely technical machining. 
 When I removed the insert that carries the cue ball, from
 the hull, I found it wondewas damaged and causes the cue
 ball to drag causing damage to the ball.  Since I do not
 have the skills and equipment to machine that part with the
 radius in it, I will try the valve idea.
